Abstract

Background

The relationship between depression and sexual behaviour among men who have sex with men (MSM) is poorly understood.

Aims

To investigate prevalence and correlates of depressive symptoms (Patient Health Questionnaire-9 score ≥10) and the relationship between depressive symptoms and sexual behaviour among MSM reporting recent sex.

Method

The Attitudes to and Understanding of Risk of Acquisition of HIV (AURAH) is a cross-sectional study of UK genitourinary medicine clinic attendees without diagnosed HIV (2013–2014).

Results

Among 1340 MSM, depressive symptoms (12.4%) were strongly associated with socioeconomic disadvantage and lower supportive network. Adjusted for key sociodemographic factors, depressive symptoms were associated with measures of condomless sex partners in the past 3 months (≥2 (prevalence ratio (PR) 1.42, 95% CI 1.17–1.74; P=0.001), unknown or HIV-positive status (PR 1.43, 95% CI 1.20–1.71; P<0.001)), sexually transmitted infection (STI) diagnosis (PR 1.46, 95% CI 1.19–1.79; P<0.001) and post-exposure prophylaxis use in the past year (PR 1.83, 95% CI 1.33–2.50; P<0.001).

Conclusions

Management of mental health may play a role in HIV and STI prevention.

HIV transmission is ongoing among gay, bisexual and other men who have sex with men (MSM) in the UK, with 3320 new diagnoses in 2015. Reference Chau, Kirwan, Brown, Gill and Delpech1 Although HIV prevention has been a public health priority among MSM in the UK and Europe, mental health has not generally been a focus of European studies of HIV and sexually transmitted infection (STI) risk and prevention among MSM. The potential role of depression in sexual health and transmission of HIV is not well understood.

Quantitative link in epidemiological literature

Assessment of the association between depression and condomless sex (CLS) in epidemiological studies may be problematic, because individuals with depressive symptoms may be more likely to engage in CLS or, on the other hand, more likely to have lowered libido and less interest in sex. The direction in which the association operates may be a function of a number of factors including the severity of the symptoms or the type of coping mechanism employed by the individual. Reference Crepaz and Marks2 Such opposing trends could result in an observed overall lack of association. The only meta-analysis that has examined this association among MSM included studies conducted up to 1999. Reference Crepaz and Marks2 Findings across studies were inconsistent. In combined estimates, there was no significant relationship between depression and measures of CLS. Stratifying by sample population (MSM, substance users or other) and HIV status did not significantly moderate the association. A number of studies of MSM and HIV-negative MSM published since 1999 have reported a significant relationship between depressive symptoms and CLS in unadjusted analysis Reference Beck, McNally and Petrak3Reference De Santis, Colin, Provencio Vasquez and McCain6 and after adjusting for sociodemographic, lifestyle, psychosocial and/or sexual behaviour measures. Reference Alvy, McKirnan, Mansergh, Koblin, Colfax and Flores7Reference Reisner, Mimiaga, Skeer and Mayer14 However, some studies have failed to find a relationship in unadjusted analysis Reference Stall, Mills, Williamson, Hart, Greenwood and Paul15Reference Nelson, Simoni, Pearson and Walters20 or after adjusting for sociodemographic, lifestyle and psychosocial measures. Reference Parsons, Grov and Golub21 The association and magnitude of effect may vary according to the setting and specific sample of MSM under study. The vast majority of studies have been conducted in the USA. To date, only two relatively small European studies have investigated the relationship between depression and CLS among MSM, both finding that depressive symptoms were associated with CLS measures. Reference Beck, McNally and Petrak3,Reference Vanden Berghe, Nostlinger and Laga5

Theoretical link in self-regulation and coping literature

It has been suggested that some individuals may engage in CLS, not because they lack information or intentions to be safe, but because sexuality is a non-rational emotionally charged area. A number of factors may have an impact on non-rationality of sexual risk behaviour, such as psychological symptoms (e.g. depression may distort perceptions of personal vulnerability) and recreational drug use (which may lead to increased sexual arousal and disinhibition). However, it is also possible that any such associations are bi-directional; experiences of sexual risk may increase vulnerability to symptoms of depression and drug use. Reference McKirnan, Ostrow and Hope22

Cognitive escape is a theoretical process whereby individuals turn their attention away from threatening cues, completely or partially escaping from personal self-awareness. There are two potential pathways through which cognitive escape might lead to CLS. The first is fatalistic beliefs about HIV, the notion that acquiring HIV is inevitable. The second is ‘determination’ to perceive oneself to be at low risk, despite evidence to the contrary. Reference Krohne and Krohne23 Individuals with depression have an increased propensity to engage in escapism, characterised by fatalistic beliefs, as a coping strategy. Reference Alvy, McKirnan, Mansergh, Koblin, Colfax and Flores7, Reference McKirnan, Ostrow and Hope22 The association between depression and CLS may also be due to the tendency of individuals with depressive symptoms to experience low self-efficacy. The principle of self-efficacy, as conceptualised in social cognitive theory, is that regardless of one's attitude, action (e.g. ensuring condom use during sex) requires additional confidence in one's ability to produce a certain outcome (e.g. sexual safety). Reference Bandura24 Conceptually, cognitive escape and self-efficacy are linked. Low self-efficacy is thought to make escape tendencies more likely. It is possible that depression may lower one's perceived ability to exercise self-protective control in sexual situations where this is desired (lowered self-efficacy for sexual safety) and lead to cognitive escape. Reference Alvy, McKirnan, Mansergh, Koblin, Colfax and Flores7 Recreational drug use may also play a role in these relationships. In addition to any direct effect on autonomic or central nervous system mechanisms, substances may be used strategically to induce a state of cognitive release in sexual settings. Men with depressive symptoms may be more likely to engage in recreational drug use, perhaps as a form of self-medication. Reference McKirnan, Ostrow and Hope22

Study objectives

This study uses data from the Attitudes to and Understanding of Risk of Acquisition of HIV (AURAH) Study of individuals attending genitourinary medicine (GUM) clinics across the UK. It investigates, among HIV-negative or unknown status MSM who reported recent sex: (1) the prevalence of depressive symptoms and the association with sociodemographic and lifestyle factors; (2) the relationship of depressive symptoms with CLS and other sexual behaviour measures, and the potential confounding effect of recreational drug use; (3) the association between depressive symptoms and measures of self-efficacy for sexual safety; and (4) the prevalence of treatment for depression, and association of treated depression with sexual behaviour.

Men who did not report any sex in the past 3 months were excluded from this analysis, because depression may also be linked to a lack of sexual activity, Reference Crepaz and Marks2 and it was of particular interest to compare those having condom-protected sex with those having CLS.

Method

AURAH Study is a cross-sectional, self-administered questionnaire study in individuals attending 20 GUM clinics across the UK from June 2013 to November 2014. Reference Sewell, Speakman, Phillips, Lampe, Miltz and Gilson25 Individuals aged 18 years or over without diagnosed HIV were eligible for inclusion. A total of 4380 eligible participants were approached over the study period, of whom 2630 completed the questionnaire (response rate: 60%). The confidential, self-administered questionnaire included questions on sociodemographics, health, lifestyle and sexual behaviour.

Men were classified as MSM if they met at least one of the following criteria: (1) reported being gay or bisexual (including other plurisexual identity labels: pansexual, omnisexual, open or queer, i.e. identities that are not explicitly based on attractions to one sex or gender Reference Galupo, Lomash and Mitchell26 ), (2) reported anal sex with a man in the past 3 months or (3) reported having disclosed to their family, friends or workmates as being gay, bisexual and/or attracted to men.

Clinically significant depressive symptoms

The Patient Health Questionnaire-9 (PHQ-9) was used to measure the prevalence of depressive symptoms. Reference Kroenke, Spitzer and Williams27 A score of ≥10 was considered to indicate clinically significant depressive symptoms; details given in Box 1. The score was further classified in terms of severity of depressive symptoms: moderate (10–14), moderately severe (15–19) and severe (20–27). In addition, participants were asked whether they were receiving medical treatment or therapy for depression.

Box 1 The Patient Health Questionnaire 9-item scale (PHQ-9) Reference Kroenke, Spitzer and Williams27 for depressive symptoms

‘Over the past 2 weeks, how often have you been bothered by any of the following problems?’
  1. 1 Little interest or pleasure in doing things.

  2. Feeling down, depressed or hopeless.

  3. Trouble falling or staying asleep, or sleeping too much.

  4. Feeling tired or having little energy.

  5. Poor appetite or overeating.

  6. Feeling bad about yourself – or that you are a failure or have let yourself or your family down.

  7. Trouble concentrating on things, such as reading the newspaper or watching television.

  8. Moving or speaking so slowly that other people could have noticed/being so restless that it is hard to sit still.

  9. Thoughts that you would be better off dead or of hurting yourself in some way.

k Having a supportive network of individuals in one's life was assessed by a modified version of the Duke-UNC Functional Social Support Questionnaire using five questions that asked about the amount of support Reference Broadhead, Gehlbach, de Gruy and Kaplan31 (with the following response options: (1) much less than I would like; (2) less than I would like; (3) some, would like more; (4) almost as much as I would like; (5) as much as I would like). The total score across the five questions for each participant was generated and categorised as follows: 5–10 (lower levels of a supportive network), 11–24 (medium levels of a supportive network; further categorised into scores of 11–15, labeled 4, 16–20, labeled 3, and 21–24, labeled 2) and 25 (higher levels of a supportive network).

l Men were asked whether they ‘smoke cigarettes regularly (at least one per day)’.

m Higher-risk drinking is based on the first two questions of the WHO AUDIT-C questionnaire. Higher risk drinking is indicated by a score of ≥6 and lower risk drinking or no alcohol consumption by a score of <6. Reference Babor, Higgins-Biddle, Saunders and Monteiro32

n Wald test using modified Poisson regression.

Sexual behaviour measures

The questionnaire included questions about anal sex with men, and vaginal or anal sex with women in the past 3 months, and sex without a condom. Four measures of CLS (anal or vaginal) were defined: (1) CLS with one or more partners, (2) CLS with two or more partners, (3) CLS with unknown and/or HIV-positive status partner(s) (men who reported no CLS partners of unknown HIV status, and only one HIV positive CLS partner who was a long-term partner and with whom they ‘thought the risks of catching HIV were low because their partner was taking ART’ were not counted) and (4) receptive CLS with unknown HIV-status partner(s). All reports of CLS were included regardless of the partner's gender. Participants were asked whether they had been diagnosed with an STI in the past year. STI diagnosis was defined as report of one of four bacterial infections: gonorrhoea, chlamydia, syphilis or lymphogranuloma venereum (LGV). Furthermore, participants were asked whether they had taken antiretroviral drugs after CLS to reduce the risk of becoming infected with HIV, post-exposure prophylaxis (PEP), in the past year. The final two measures considered concerned partner numbers: reporting 11 or more new sexual partners in the past year and reporting group sex (sex with more than one other person on the same occasion) in the past 3 months.

Measures of self-efficacy for sexual safety

The questionnaire included a number of statements on attitudes towards condom use, with response options: strongly agree, tend to agree, undecided or no opinion or not relevant to me, tend to disagree, strongly disagree. The following statement was used to measure self-efficacy: ‘I feel confident that, if I want to, I can make sure a condom is used during sex with any partner, in any situation’. Strong agreement with this statement was considered to indicate high self-efficacy for sexual safety. Agreement (‘strong’ or ‘tend to’) with the following statement was considered to indicate difficulty in negotiating condom use: ‘I find it difficult to discuss condom use with any new sexual partner’.

Men were also asked reasons for non-condom use in the past 3 months, for which one or more of the following options could be chosen: ‘Didn't think about using a condom or did not have a condom’, ‘Don't like using condoms or it's more enjoyable/close without a condom’, ‘My partner didn't want to use a condom’, ‘Felt unable to discuss condom use’, ‘Got carried away or was under the influence of alcohol or drugs’ and ‘Difficult for me/partner to keep erection or ejaculate when using a condom’.

Statistical analysis

Associations were assessed by χ 2 tests, χ 2 tests for trend and Fisher's exact test (when expected numbers were small) for univariable analysis, and modified Poisson regression with a robust variance estimator to produce adjusted prevalence ratios (PRs) for multivariable analysis. Reference Zou28 PRs were chosen for their ease of interpretation. It should be noted that, where the prevalence of the different outcome measures differ, it is not appropriate to compare the magnitude of PRs for depression across these different outcome measures.

For assessment of the relationship of sociodemographic and lifestyle factors with depressive symptoms, associations are presented unadjusted, and adjusted for the following socio-demographic factors: age group (<25, 25–29, 30–39 or ≥40 years), country of birth (UK born or non-UK born/missing), self-reported sexual identity (gay or bisexual/straight), university education (yes or no/missing), ongoing relationship (yes or no/missing) and study region (London, South or other – see Table 1 footnote for definition).

For assessment of the relationship of depressive symptoms with sexual behaviour measures, associations are presented unadjusted, adjusted for the above sociodemographic factors and finally adjusted for the above sociodemographic factors plus current smoking (yes or no/missing), higher risk alcohol consumption (yes or no/missing; see Table 1 for definition) and number of recreational drugs used in the past 3 months (none, 1, 2–4 or ≥5), to assess the extent to which the associations were attenuated when accounting for smoking, drug and alcohol use.

Measures of self-efficacy for sexual safety were hypothesised a priori to be on the casual pathway between depressive symptoms and sexual risk behaviour. The association of depressive symptoms with self-efficacy measures and the association of self-efficacy measures with sexual behaviour measures were investigated.

Finally, the prevalence of treatment for depression was assessed, and the associations with sexual behaviour measures were assessed according to the presence or absence of depressive symptoms and treatment for depression.

The proportion of missing values was <5% for all variables used in analyses; missing values were incorporated into specific categories for some variables (see Table 1). All analyses were performed by STATA statistical software 29 and reported according to the STROBE guidelines. 30 Several sensitivity analyses were undertaken: (1) adjusting for age grouped into six categories (<25, 25–29, 30–34, 35–39, 40–44 or ≥45 years), (2) adjusting for age as a continuous variable, (3) excluding missing values when defining each variable and (4) assessing the association between depressive symptoms and sexual behaviour measures only among men who reported anal sex with a man in the past 3 months. In each case, the findings were very similar to the main analysis (results not shown).

Ethical approval

The research protocol and all versions of the study documents were approved by the designated research ethics committee (NRES committee London-Hampstead, ref: 13/LO/0246).

Results

In total, 2630 individuals participated in the AURAH Study, of whom 1484 were defined as MSM. The current analysis is based on 1340 MSM who reported anal or vaginal sex in the past 3 months. Of these, 1238 (92.4%) reported anal sex with men only, 66 (4.9%) reported sex with both men and women and 36 (2.7%) reported sex with women only in the past 3 months. Eighty-nine per cent of the 1340 men identified as gay, 9.5% as bisexual or another plurisexual identity label and 1.4% as straight. Eighty-two per cent of men were of White ethnicity; median age was 31 years. Overall, 57% were born in the UK, 67% had a university degree and 76% were attending a clinic in London (Table 1).

Depressive symptoms

The prevalence of depressive symptoms (PHQ-9 score ≥10) was 12.4% (166 of 1340). Of these 166 men, 55% had moderate depressive symptom severity, 30.1% had moderately severe symptoms and 15.1% had severe symptoms of depression.

Correlates of depressive symptoms

In unadjusted analysis, depressive symptoms were strongly associated with indicators of lower socioeconomic status (financial hardship, non-employment, rented or unstable housing and non-university education), and there was an exceptionally strong association with lower reported levels of a supportive network. Depressive symptoms were also associated with younger age, bisexual (or other plurisexual) identity, Midlands or Yorkshire or Humber region of recruitment, disclosing being MSM to few or no work colleagues, smoking, higher-risk drinking and greater number of recreational drugs used (Table 1). After adjusting for key sociodemographic factors, these associations remained, with some attenuation in the magnitude of effect, with the exception of study region and smoking, which were no longer significantly associated with depressive symptoms (Table 1).

Sexual behaviour measures

Overall, 63.7% (n=853) of men reported CLS in the past 3 months. Of these, 91.7% (n=782) had CLS with men only, 3.9% (n=33) had CLS with both men and women and 4.5% (n=38) had CLS with women only. The prevalence of CLS and other sexual behaviour measures is presented in Table 2. The prevalence of high self-efficacy was 67.2% (n=900) and 10.6% (n=142) for difficulty negotiating condom use. Among the 853 men who reported CLS, the reasons indicated for non-condom use (788 total responses) were as follows: got carried away or under the influence of alcohol or drugs (n=369; 43.3%), don't like or more enjoyable without (n=353; 41.4%), their or their partner's difficulty in keeping an erection or ejaculating (n=205; 24.0%), partner not wanting to (n=147; 17.2%), didn't think about it or didn't have (n=131; 15.4%), and felt unable to discuss (n=37; 4.3%).

a Men who reported no CLS partners of unknown HIV status, and only one HIV positive CLS partner who was a long-term partner and with whom they ‘thought the risks of catching HIV were low because their partner was taking ART’ were not counted as positive for this measure.

b Includes men who reported always being the receptive partner and those who reported being sometimes the receptive and sometimes insertive partner. Only men who reported that they did not know the HIV status of any of their partners could be included, as for those who reported knowing some or all of their partners’ HIV status, it was not possible to distinguish whether this was the HIV-positive partner with whom the participant had insertive or receptive CLS.

Relationship between depressive symptoms and sexual behaviour

Men with depressive symptoms (n=166) were more likely than those without (n=1174) to report measures of CLS partners in the past 3 months: ≥1 (74.7% v. 62.1%), ≥2 (44.6% v. 30.4%), unknown and/or HIV-positive status (50.6% v. 33.2%), receptive unknown status (22.9% v. 12.7%). They were also more likely to report diagnosed bacterial STI (42.2% v. 30.1%) and PEP use (23.5% v. 14.3%) in the past year (P<0.01 for all, χ 2 tests). The prevalence of CLS with one or more partners was 70.3% among men with moderate depressive symptom severity, 78.0% among men with moderately severe symptoms and 84.0% among men with severe symptoms of depression.

After adjusting for key sociodemographic factors, depressive symptoms were associated with all measures of CLS partners (≥1 (PR 1.18, 95% CI 1.06−1.30; P=0.002), ≥2 (PR 1.42, 95% CI 1.17–1.74; P=0.001), unknown and/or HIV-positive status (PR 1.43, 95% CI 1.20–1.71; P<0.001), receptive unknown status (PR 1.60, 95% CI 1.14–2.24; P=0.006)) and with bacterial STI diagnosis (PR 1.46, 95% CI 1.19–1.79; P<0.001) and PEP use (PR 1.83, 95% CI 1.33–2.50; P<0.001) (Fig. 1). After adjusting additionally for smoking, alcohol and recreational drug use, most of these associations were attenuated to some extent, but they remained significant (Fig. 1). Associations were also apparent among men who had not taken recreational drugs in the past 3 months (data not shown).

Depressive symptoms were not associated with having 11 or more new sexual partners in the past year or with group sex in the past 3 months, in unadjusted or adjusted analyses (Fig. 1).

Self-efficacy for sexual safety: relationship with depressive symptoms and sexual behaviour

Men with depressive symptoms were less likely to report high self-efficacy for sexual safety (56.6% v. 68.7%; P=0.002) and more likely to report difficulty negotiating condom use (18.7% v. 9.5%; P<0.001) than men without. Adjusted for key sociodemographic factors, depressive symptoms were inversely associated with self-efficacy (PR 0.82, 95% CI 0.71–0.94; P=0.006) and were associated with difficulty negotiating condom use (PR 1.77, 95% CI 1.18–2.63; P=0.005). These associations remained with some attenuation, after additional adjustment for smoking, alcohol and recreational drug use (data not shown).

Men with high self-efficacy were less likely than those without to report CLS partners: ≥1 (55.7% v. 80.0%), ≥2 (24.3% v. 48.0%), unknown and/or HIV-positive status (26.9% v. 52.7%), receptive unknown status (10.3% v. 21.4%) and STI diagnosis (29.2% v. 36.4%), and PEP use (13.6% v. 19.3%); P≤0.01 for all. Men who reported difficulty negotiating condom use were more likely than those who did not to report CLS partners: ≥1 (80.3% v. 61.7%), ≥2 (45.8% v. 30.5%), unknown and/or HIV-positive status (55.6% v. 33.0%) and receptive unknown status (23.2% v. 12.9%); P≤0.001 for all. Adjusted for key sociodemographics (and additionally adjusted for lifestyle factors), high self-efficacy was associated with lower prevalence of CLS partners, STI diagnosis and PEP use, but not high partner numbers or group sex (Fig. 2). Similar, albeit weaker, associations were found when investigating difficulty negotiating condom use (Fig. 3).

Among men who reported CLS, men with depressive symptoms were more likely than those without to report having gotten carried away or been under the influence of alcohol or drugs (54.8% v. 41.3%; P=0.005), their or their partner's difficulty in keeping an erection or ejaculating with a condom (32.3% v. 22.6%; P=0.020) and their partner not wanting to use a condom (23.4% v. 16.2%; P=0.050).

Receiving medical treatment or therapy for depression

Overall, the proportion of men who reported receiving treatment (medicine or therapy) for depression was 9.2% (123 of 1340). Treatment for depression was reported by 28.9% (n=48) of the 166 men with depressive symptoms and 6.4% (n=75) of the 1174 men without. To more accurately present the prevalence of men with depression who were receiving treatment, men with either depressive symptoms (PHQ-9 ≥10) or who reported receiving treatment for depression were considered to account for all men with any evidence of current depression. Among these 241 men, 51.0% (n=123) were receiving treatment for depression.

The prevalence of CLS partner measures, STI diagnosis and PEP use according to evidence of depression (symptoms and/or treatment) is presented in Table 3. Men with any evidence of current depression tended to be more likely to report measures of sexual risk than those without evidence of depression. Adjusted PRs of CLS with one or more partners, STI diagnosis and PEP use were higher for men who reported depressive symptoms (with or without treatment) than for those who reported treatment but no current symptoms. For the other measures of CLS, prevalence was elevated for all three depression groups, compared with no depression.

Discussion

AURAH is the largest questionnaire study of sexual behaviour undertaken among individuals attending GUM clinics in the UK and one of the first UK studies to assess the association of depressive symptoms with CLS. Depressive symptoms were associated with all measures of CLS, including bacterial STI diagnosis and PEP use, independently of sociodemographic and lifestyle factors. However, depressive symptoms were not associated with having a higher number of new sexual partners or group sex.

Burden of depressive symptoms among MSM and associated factors

Minority stress theory and masculine socialisation stress theory stipulate that gay (and bisexual) men may experience high levels of psychological distress as a result of conflict produced between mainstream social norms and minority values. Social pressure to conform to traditional gender-normative behaviour may increase shaming and victimisation of men in sexual minority groups, and risk of internalised homophobia, adverse mental health outcomes, violence-prone partnerships and/or substance use for these men. Reference Stall, Friedman, Catania, Wolitski, Stall and Valdiserri33,Reference Meyer34 A recent systematic review of mainly US or Canadian studies reported elevated levels of depression among sexual minorities compared with heterosexual individuals, Reference Ploderl and Tremblay35 but there is less evidence from the UK. In this study, the prevalence of depressive symptoms among MSM in 2013–2014 was 12%. A general population-based survey in England in 2007–2008 found the prevalence of depressive symptoms to be 7% by the same definition (PHQ-9 ≥10) and this figure included women, among whom rates of depression are often higher. This suggests prevalence may be somewhat higher among MSM compared with other men, but other sociodemographic factors may confound this comparison. Reference Paranjothy, Gallacher, Amlot, Rubin, Page and Baxter36 There are a number of other probability-based sample and general population-based survey studies that have collected information on depression among individuals in the UK; however, none have incorporated the PHQ-9. Reference Stewart, Prince, Harwood, Whitley and Mann37Reference Bebbington, Brugha, Coid, Crawford, Deverill and D'Souza42 In the most recent (2010–2012) British National Survey of Sexual Attitudes and Lifestyles (NATSAL), a shortened version of the PHQ-9 was used (PHQ-2, which includes only the first two questions): 8.9% (95% CI 5.5–14.3, n/N=17/190) of all MSM, 6.4% (95% CI 3.5–11.7, n/N=7/107) of gay-identified MSM and 8.9% (95% CI 8.1–9.8, n/N=451/5069) of men who reported sex exclusively with women screened positive for depression. Reference Mercer, Prah, Field, Tanton, Macdowall and Clifton43 By the same definition (PHQ-2 ≥3), the prevalence of depression in MSM included in this AURAH analysis was 9.3%; among all MSM in AURAH the comparable prevalence was 9.5%.

Studies from the UK, USA and Australia have found that among MSM, markers of lower socioeconomic status and lower levels of a supportive network are consistently strongly associated with symptoms of depression. Reference Mao, Kidd, Rogers, Andrews, Newman and Booth44Reference Hickson, Davey, Reid, Weatherburn and Bourne46 Similarly, in this study these factors were among the strongest correlates of depressive symptoms, suggesting a critical role of socioeconomic hardship in poor mental health among UK MSM, as has been found in the general population. Reference Bebbington, Brugha, Coid, Crawford, Deverill and D'Souza42,Reference Fone, Dunstan, Williams, Lloyd and Palmer47,Reference Stafford and Marmot48

Younger age and recreational drug use were associated with depressive symptoms among MSM in AURAH, as has been found in other studies. Reference Mao, Kidd, Rogers, Andrews, Newman and Booth44,Reference Hickson, Davey, Reid, Weatherburn and Bourne46 The prevalence of depressive symptoms was twice as high in men reporting a bisexual (or other plurisexual) identity compared with a gay sexual identity (22.1% v. 11.4%, respectively), a finding that has also been reported in other studies. Reference Hickson, Davey, Reid, Weatherburn and Bourne46,Reference Marshal, Dietz, Friedman, Stall, Smith and McGinley49 This may reflect higher levels of social support available in a more established and potentially more cohesive community, such as the gay community. Bisexual men may be even more vulnerable to isolation as a sexual minority. Low levels of disclosure of sexual orientation to work colleagues, smoking and higher risk alcohol use were also associated with depressive symptoms.

Depressive symptoms and sexual behaviour

To date, two European studies have investigated the relationship between symptoms of depression and sexual behaviour among MSM. In a UK GUM clinic sample of 123 MSM in 1999, a higher prevalence of depressive symptoms (Hospital Anxiety and Depression Score (HADS) ≥11) was observed among men who reported CLS with an HIV-positive or unknown status partner v. other men (χ 2 test 13.6% v. 2.7%, based on eight cases of depression only). Reference Beck, McNally and Petrak3 In a Belgian volunteer and online sample of 591 HIV-negative MSM who reported anal sex with a casual partner (2008), depressive symptoms (CES-D >21) were associated with CLS (odds ratio (OR) 1.66, 95% CI 1.16–2.37; P=0.006) in unadjusted analysis. Reference Vanden Berghe, Nostlinger and Laga5 In US studies, the association between depressive symptoms and sexual risk among MSM has been more consistently demonstrated among samples where the vast majority of men reported recent sex and recreational drug use (Project MIX and Frontiers in Prevention Reference Alvy, McKirnan, Mansergh, Koblin, Colfax and Flores7,Reference Houston, Sandfort, Dolezal and Carballo-Dieguez9 ), compared with samples which included a higher proportion of men who did not report recent sex (Urban Men's Health Study and Sex and Love Study Reference Stall, Mills, Williamson, Hart, Greenwood and Paul15,Reference Parsons, Grov and Golub21 ). It has been suggested that in the former samples, men may have been more likely to have an externalised response to depressive symptoms (such as cognitive escape) rather than an internalised response such as withdrawal. Reference Alvy, McKirnan, Mansergh, Koblin, Colfax and Flores7 This may in part explain why a strong relationship was observed in this study among a sexually active GUM clinic sample.

Depression, alcohol and drug use and sexual behaviour

Our findings suggest that the link between depression and CLS may in part be confounded by higher levels of drug or alcohol use among those with depression, but drug and alcohol use are unlikely to solely explain this relationship. It has been further stipulated in syndemic theory that it is the synergistic interactions of two or more co-occurring psychosocial health problems, such as depression, drug use, childhood sexual abuse and intimate partner violence, that compound the risk of HIV infection among MSM. Reference Parsons, Grov and Golub21 Measurement of these factors together with markers of certain personality traits (sensation seeking and sexual compulsivity) would be useful in further studies.

Self-efficacy for sexual safety

Our findings suggest that low self-efficacy for sexual safety and difficulty negotiating condom use may be potential mechanisms through which depression leads to CLS, which may explain why a relationship was observed with CLS measures but not higher partner numbers. The fact that men who reported depressive symptoms were more likely to report PEP use suggests that although depression may impair discussion or negotiation of safe sex practices, there is still an overarching desire to be safe and protect oneself after this interaction is over.

Symptoms and treatment for depression in relation to sexual risk

In this study, there was limited evidence to imply that sucessful treatment of depression (reporting treatment, but negative for depressive symptoms according to PHQ-9) may reduce sexual risk. However, the extent to which this question can be addressed given the cross-sectional design of the study is limited, and inference may be complicated by a number of factors including severity of symptoms before treatment, type, duration and frequency of treatment, timing of treatment in relation to symptoms, the presence of other psychological conditions and sensitivity of the PHQ-9 in capturing all cases of depressive symptoms. There does appear to be some evidence of potential undertreatment of possible clinically significant depressive conditions.

Strengths and limitations

Strengths of this study include the large sample size and the fact that only men who reported sex in the past 3 months were included in analysis. This is important, as in some men depression may result in lowered libido and lack of sexual activity. In terms of limitations, the prevalence of depression and associations with sexual behaviour may have differed among the 40% of individuals approached who did not complete the questionnaire. Furthermore, the cross-sectional methodology used in this study prohibits us from making inferences about causality. In particular, the PHQ-9 inquires about symptoms during the previous 2 weeks, whereas the recall periods for sexual behaviour were longer (past 3 months or past year). Because depression questionnaires aim to provide a diagnostic measure of a chronic mental health condition, it is not unreasonable to assume that in many participants depression may have preceded the recent sexual behaviour reported. The strong adjusted associations found between depressive symptoms and CLS, and the evidence for low self-efficacy as a mechanism for these relationships, provide some support in favour of a causal association. Furthermore, there appeared to be some evidence of a gradient in CLS prevalence with more severe depressive symptoms. On the other hand, the elevated prevalence of some CLS measures among men who reported treatment for depression but were not PHQ-9 positive (i.e. apparently successful treatment) could be regarded as evidence that causality, at least to some extent, may operate in the other direction. Finally, our study is important in the context of GUM services but it does not necessarily allow us to generalise to all MSM in the UK.

Implications

Our findings suggest the need for an integrated sexual health approach. Screening for depressive symptoms using brief instruments in sexual health services may be useful in identifying individuals who could be offered referral for potential interventions. Socioeconomic advantage and supportive networks may be critical factors for mental health. Care should be taken to include men with plurisexual identities in efforts to promote supportive networks and manage symptoms of depression. In parallel, integration of (or good linkage to) substance use services could also play a role in management of depression and reduction of sexual risk.
