The aim of this study was to explore and identify why young adults aged between 18 and 30 years in the UK and France do or do not consume dairy products. Several studies have associated dairy products with a healthy diet, and the production of soft dairy, i.e. milk, yoghurt, and soft cheese, as more environmentally friendly than some other animal-based products. Yet recent reports highlight that dairy intake is lower than recommended for health, especially among young adults. Using a qualitative methodology, forty-five participants aged 18–30 years (UK: n = 22; France: n = 23) were asked about their reasons for (non)consumption of a wide range of dairy products. Audio-recorded focus groups and individual interviews were conducted in English in the UK and in French in France, transcribed and coded. A thematic analysis found four themes and sixteen sub-themes (theme product-related: sub-themes sensory, non-sensory, composition; theme individual-related: sub-themes mode of consumption, preferences, personal reasons, knowledge, attitudes and concerns, needs or cravings; theme cultural aspects: sub-themes product categorization, social norms, use; theme market offering: sub-themes alternative, packaging, value for money, availability) to influence participants’ dairy (non)consumption in both countries. A seventeenth sub-theme (theme cultural aspects: sub-theme structure of the meal) was found to influence dairy consumption only in France. Further studies are needed to investigate these themes within larger samples, but these findings contribute to understanding dairy (non)consumption in young adults in the UK and France and may aid the development of strategies to improve young adults’ diets.

Timing of food intake is an emerging aspect of nutrition; however, there is a lack of research accurately assessing food timing in the context of the circadian system. The study aimed to investigate the relation between food timing relative to clock time and endogenous circadian timing with adiposity and further explore sex differences in these associations among 151 young adults aged 18–25 years. Participants wore wrist actigraphy and documented sleep and food schedules in real time for 7 consecutive days. Circadian timing was determined by dim-light melatonin onset (DLMO). The duration between last eating occasion and DLMO (last EO-DLMO) was used to calculate the circadian timing of food intake. Adiposity was assessed using bioelectrical impedance analysis. Of the 151 participants, 133 were included in the statistical analysis finally. The results demonstrated that associations of adiposity with food timing relative to circadian timing rather than clock time among young adults living in real-world settings. Sex-stratified analyses revealed that associations between last EO-DLMO and adiposity were significant in females but not males. For females, each hour increase in last EO-DLMO was associated with higher BMI by 0·51 kg/m2 (P = 0·01), higher percent body fat by 1·05 % (P = 0·007), higher fat mass by 0·99 kg (P = 0·01) and higher visceral fat area by 4·75 cm2 (P = 0·02), whereas non-significant associations were present among males. The findings highlight the importance of considering the timing of food intake relative to endogenous circadian timing instead of only as clock time.

When young people leave the musical world of their school environment, a lack of clear routes into adult musical engagement brings a risk of wasted ability, motivation and enjoyment, which arguably undermines the value of music education. This study explored the factors that influence continued musical participation among young British adults who had been actively engaged in school music. Musical participation is defined in this research as group music-making in either a formal or informal setting. Participants (n = 102) completed an online questionnaire or were interviewed (n = 6) about their past and present musical experiences along with future expectations for music-making. The stark headline finding was that while 87% of participants had intended to continue with music-making beyond school, only 48% had found groups to join. Nonetheless, 78% expected to continue with music-making in the future. Our research therefore suggests that any break from musical participation need not be permanent for individuals who have established strong musical identities through their early experiences. To conclude, we present a model of lifelong musical participation that illustrates the influences, motivations and choices that contribute to sustained musical engagement.

Financial literacy is today globally recognized as an essential life skill. However, many young adults have large debts due to consumption loans, and the situation in Sweden is escalating. Previous research has indicated a low financial literacy, and that the prevalence of mental illness is high within the group. In this report, we studied financial literacy, personal financial situation, and self-reported mental illness in a Swedish sample, comprising 2 057 respondents between 18 and 29 years. Our main findings indicate that financial literacy is lower than has previously been described, especially concerning knowledge about inflation. One in four reported they had consumption loans, one in three had loans to relatives, almost half of the respondents had perceived financial difficulties during the past year, and one out of ten had turned to the budget and debt advisor to receive help. Women showed lower financial literacy compared to men, indicating an important gender aspect. Our findings per se are sounding the alarm for policymakers to immediately pay attention in order to prevent the risk of becoming overindebted early in life. The present study highlights the urgent need to further study the complex relationship between financial literacy, personal financial situation, and mental illness among young adults.

Alcohol is the number one substance used by young people and people of college age. Binge drinking (BD) in this age group is considered one of the most important global health issues, as much harm accrues from it and even lives are lost. This study aimed to review the interventions to curb BD or encourage responsible drinking among college students and young adults. MEDLINE (PubMed), ERIC and APA PsycINFO were searched. The selected articles were published in English and had to evaluate a BD reduction program through a randomized control trial (RCT) among college students or young adults between the ages of 17–24 years. The exclusion criteria included research not published in English, systematic review articles, qualitative studies, designs other than RCTs and discussion articles on college students drinking with no findings. The three reviewers independently screened and extracted the data using the PRISMA guidelines. The overall quality of the studies was assessed. Then, 10 of the 12 interventions studied were found to be successful in reducing BD among college students, though the effect sizes were small to medium. A minority of the studies used behavior change theories. Effective interventions for reducing BD among college students and young adults should include robust behavior change theories, longer follow-up time and the operationalization of multiple outcomes. Process evaluation is needed to be conducted in these studies.

The Developmental Origins of Health and Disease (DOHaD) approach supports that nutritional exposures in early life affect an individual’s later health and risk of disease. Dietary exposure during the preconception period may also influence individual, and inter- and transgenerational health and disease risk, in both men and women. This study aimed to describe knowledge of the DOHaD approach (DOHaDKNOWLEDGE) and diet quality in preconception young adults in Norway, to assess associations between DOHaDKNOWLEDGE and a Diet Quality Score (DQS), and to assess gender differences in those above. Data from 1362 preconception young adults was obtained from the PREPARED study baseline dataset. The sample had 88% women participants, a mean age of 27 years, 36% had overweight or obesity, and 77% had higher level of education. DOHaDKNOWLEDGE was assessed by the participants’ agreement to five statements using a Likert scale. Diet quality was assessed using aspects of diet quality and a DQS derived from a dietary screener. We found moderate level of both DOHaDKNOWLEDGE (12/20 points) and diet quality (DQS: 60/100 points), indicating potential for improvements. Specifically, the greatest potential for diet quality improvements were observed for sugary foods, red and processed meats, legumes, and unsalted nuts and seeds. Gender differences were observed for both DOHaDKNOWLEDGE and diet quality. DOHaDKNOWLEDGE was positively associated with DQS, adjusted for sociodemographic factors, with little evidence of an interaction effect by gender. This study indicates that knowledge of the DOHaD approach is positively associated with diet quality in preconception young men and women. Future studies should consider incorporating pregnancy intentions, relationship status, and health literacy.

Emerging evidence suggests that diet therapy (nutrients, foods and dietary patterns) could be effective as a potential adjunctive treatment option for major depressive disorder. Numerous mechanisms have been proposed, including the role inflammation, oxidative stress, brain-derived neurotrophic factor, the gastrointestinal tract microbiome and tryptophan/serotonin metabolism. Despite known differences in depression characteristics and treatment responses between males and females, there are limited sex-specific studies examining the role of diet in young men specifically. This is important as young men are often reluctant to seek mental health support, so finding treatment strategies which appeal to this demographic is crucial. This brief report provides an overview of the most recent advances in the use of diet for preventing and treating depression in young men, highlighting existing challenges and opportunities for future research. We recommend that clinicians discuss the role of diet with depressed young men, so that diet may be used alongside current treatment options.

Studies show associations between prenatal maternal stress (PNMS) and child autism, with little attention paid to PNMS and autism in young adulthood. The broad autism phenotype (BAP), encompassing sub-clinical levels of autism, includes aloof personality, pragmatic language impairment and rigid personality. It remains unclear whether different aspects of PNMS explain variance in different BAP domains in young adult offspring. We recruited women who were pregnant during, or within 3 months of, the 1998 Quebec ice storm crisis, and assessed three aspects of their stress (i.e., objective hardship, subjective distress and cognitive appraisal). At age 19, the young adult offspring (n = 33, 22F / 11M) completed a BAP self-report. Linear and logistic regressions were implemented to examine associations between PNMS and BAP traits. Up to 21.4% of the variance in BAP total score and in BAP three domains tended to be explained by at least one aspect of maternal stress, For example, 16.8% of the variance in aloof personality tended to be explained by maternal objective hardship; 15.1% of the variance in pragmatic language impairment tended to be explained by maternal subjective distress; 20.0% of the variance in rigid personality tended to be explained by maternal objective hardship and 14.3% by maternal cognitive appraisal. Given the small sample size, the results should be interpreted with caution. In conclusion, this small prospective study suggests that different aspects of maternal stress could have differential effects on different components of BAP traits in young adults.

Emerging adulthood is an important developmental period, associated to mental health risk. Resilience research points to both social and personal protective factors against development of psychopathology, but there is paucity with their comprehensive study in young adults. This study provides and initial integrative approach to model multiple dimensions of perceived social support (i.e., from family, friends, significant others) and personal factor of trait resilience (i.e., coping and persistence during stress, tolerance to negative affect, positive appraisals, trust) and their hypothesized contributions to reducing depression and anxiety rates. The study was conducted with a sample of 500 Spanish emerging adults (18 to 29 years old). Regression analyses and multiple mediation models were performed to test our hypotheses. Results showed that social support from family was the dimension with the highest strength relating individual differences in resilience. Furthermore, analyses supported a differential mediating role of specific resilience factors (coping and persistence during stress, tolerance to negative affect, positive appraisals, trust) in partially accounting for the association between higher social support from family and lower depression and anxiety levels in young adults. These results may inform new programs of mental health during emerging adulthood via the promotion of different sources of social support and their related resilience pathways contributing to low emotional symptomatology at this stage of development.

Prior research has shown that racial minority groups are more likely than Whites to hold negative views of Jews. We discuss several theories that may explain this phenomenon, including group competition, anti-White attitudes manifesting as antisemitism, spillover from anti-Israel attitudes, and more. Some theories, especially those developed in the mid-20th century, may be less applicable today, particularly to young adults. Through an original survey of 3,500 Americans, including an oversample of 18–30 year olds, we discover that antisemitic views remain far more common among minorities than Whites, especially among young people. However, the racial differences do not seem to be explained by common theories cited and explored in prior literature. But with Black and Hispanic Americans agreeing with antisemitic statements at similar levels as White alt-right identifiers in our sample, our findings call for renewed interest in the topic of race and antisemitism.
