Population reductions in sodium intake could prevent hypertension, and current guidelines recommend that clinicians advise patients to reduce intake. This study aimed to estimate the prevalence of taking action and receiving advice from a health professional to reduce sodium intake in 10 US jurisdictions, including the first-ever data in New York state and Guam.

weighted prevalence and 95% confidence intervals (CI) overall and by location, demographic group, health status, and receipt of provider advice using self-reported data from the 2017 Behavioral Risk Factor Surveillance System optional sodium module

seven states, the District of Columbia, Puerto Rico, and Guam

adults aged ≥18 years

Overall, 53.6% (CI: 52.7, 54.5) of adults reported taking action to reduce sodium intake, including 54.8% (CI: 52.8, 56.7) in New York and 61.2% (CI: 57.6, 64.7) in Guam. Prevalence varied by demographic and health characteristics and was higher among adults who reported having hypertension (72.5%; CI: 71.2, 73.7) vs. those who did not report having hypertension (43.9%; CI: 42.7, 45.0). Among those who reported receiving sodium reduction advice from a health professional, 82.6% (CI: 81.3, 83.9) reported action vs. 44.4% (CI: 43.4, 45.5) among those who did not receive advice. However, only 24.0% (CI: 23.3, 24.7) of adults reported receiving advice from a health professional to reduce sodium intake.

The majority of adults report taking action to reduce sodium intake. Results highlight an opportunity to increase sodium reduction advice from health professionals during clinical visits to better align with existing guidelines.

To evaluate the association of Composite Dietary Antioxidant Index (CDAI) and Dietary Inflammatory Index (DII) with the prevalence of high-grade cervical intraepithelial neoplasia (CIN).

A cross-sectional study was conducted on women with abnormal Papanicolaou test, who underwent high-risk HPV screening and histological test through colposcopy. Dietary data were collected using a Food Frequency Questionnaire and used to assess both CDAI and DII.

Women were recruited from 2012 to 2015 at the Cervical Cancer Screening Unit of the “Azienda Sanitaria Provinciale” of Catania (Italy).

The study included 539 women with a mean age of 40.2 years, who were classified as cases (n=127 with CIN2 or more severe lesions) and controls (n= 412 with normal cervical epithelium or CIN1).

Although we observed a lower proportion of HPV-positive women among those with higher CDAI (p<0.001), the index was not associated with the diagnosis of CIN2 or more severe lesions. By contrast, women with medium or high DII showed higher odds to be diagnosed with CIN2 or more severe lesions than those with low DII (OR=2.15; 95%CI=1.11–4.17; p=0.024 and OR=3.14; 95%CI=1.50–6.56; p=0.002, respectively), after adjusting for age, HPV status, educational level, body mass index, smoking status, parity, use of oral contraceptives and supplements.

Our findings suggested that a pro-inflammatory diet might be associated with an increased risk of CIN2 and more severe lesions. However, further prospective studies should be encouraged to support this evidence.

To examine awareness and recall of healthy eating public education campaigns in five countries.

Data were cross-sectional and collected as part of the 2018 International Food Policy Study. Respondents were asked whether they had seen government healthy eating campaigns in the past year; if yes (awareness), they were asked to describe the campaign. Open-ended descriptions were coded to indicate recall of specific campaigns. Logistic models regressed awareness of healthy eating campaigns on participant country, age, sex, ethnicity, education, income adequacy and BMI. Analyses were also stratified by country.

Online surveys.

Participants were Nielsen panelists aged ≥18 years in Australia, Canada, Mexico, UK and US (n=22,463).

Odds of campaign awareness were higher in Mexico (50.9%) than UK (18.2%), Australia (17.9%), US (13.0%) and Canada (10.2%) (P<0.001). Awareness was also higher in UK and Australia versus Canada and US, and US versus Canada (P<0.001). Overall, awareness was higher among males versus females and respondents with medium or high versus low education (P<0.001 for all). Similar results were found in stratified models, although no sex difference was observed in Australia or UK (P>0.05), and age was associated with campaign awareness in UK (P<0.001). Common key words in all countries included sugar/sugary drinks, fruits and vegetables, and physical activity. The top five campaigns recalled were Chécate, mídete, muévete (Mexico), PrevenIMSS (Mexico), Change4Life (UK), LiveLighter® (Australia), and Actívate, Vive Mejor (Mexico).

In Mexico, UK and Australia, comprehensive campaigns to promote healthy lifestyles appear to have achieved broad, population-level reach.

Dietary interventions did not prevent depression onset nor reduced depressive symptoms in a large multi-center randomized controlled depression prevention study (MooDFOOD) involving overweight adults with subsyndromal depressive symptoms. We conducted follow-up analyses to investigate whether dietary interventions differ in their effects on depressive symptom profiles (mood/cognition; somatic; atypical, energy-related).

Baseline, 3-, 6-, and 12-month follow-up data from MooDFOOD were used (n = 933). Participants received (1) placebo supplements, (2) food-related behavioral activation (F-BA) therapy with placebo supplements, (3) multi-nutrient supplements (omega-3 fatty acids and a multi-vitamin), or (4) F-BA therapy with multi-nutrient supplements. Depressive symptom profiles were based on the Inventory of Depressive Symptomatology.

F-BA therapy was significantly associated with decreased severity of the somatic (B = −0.03, p = 0.014, d = −0.10) and energy-related (B = −0.08, p = 0.001, d = −0.13), but not with the mood/cognition symptom profile, whereas multi-nutrient supplementation was significantly associated with increased severity of the mood/cognition (B = 0.05, p = 0.022, d = 0.09) and the energy-related (B = 0.07, p = 0.002, d = 0.12) but not with the somatic symptom profile.

Differentiating depressive symptom profiles indicated that food-related behavioral interventions are most beneficial to alleviate somatic symptoms and symptoms of the atypical, energy-related profile linked to an immuno-metabolic form of depression, although effect sizes were small. Multi-nutrient supplements are not indicated to reduce depressive symptom profiles. These findings show that attention to clinical heterogeneity in depression is of importance when studying dietary interventions.

To explore the effect of maternal BMI class pre-pregnancy (overweight/obese versus healthy weight/underweight) on childhood diet quality and on childhood overweight/obesity risk.

Dietary data were collected using 3-day parental-completed food records for their children at ages 18 and 43 months. An index of diet quality was derived by classification of food items into core and non-core foods. Adjusted multiple linear regression analyses were used to explore the effect of maternal BMI class on diet quality in their children.

Avon, UK.

A 10% subsample of the Avon Longitudinal Study of Parents and Children. 908 children provided complete dietary data at 18 months and 769 at 43 months.

Children with overweight/obese mothers consumed greater amounts of energy from non-core foods than children with healthy weight/underweight mothers (0.20 MJ [48 kcal]/day more at 18 months (p<0.001); 0.19 MJ [45 kcal]/day more at 43 months (p=0.008)) in adjusted models. Diet quality deteriorated between 18 and 43 months (children reduced their dietary energy intake from core foods (p<0.001) and increased intake from non-core foods (p<0.001)). However, this change was not associated with maternal BMI class in adjusted models. Having an overweight/obese mother was associated with an increased odds of the child being overweight/obese at 43 months (OR 1.74 (1.17, 2.58)).

Children aged 18 and 43 months with overweight/obese mothers are likely to have a poorer quality diet than those with healthy-/underweight mothers. Parents should be supported in discouraging the consumption of non-core foods in children at these ages.

To study the association between organic food consumption and lifestyle, socio-demographics, and dietary habits.

Cohort participants completed detailed questionnaires about organic food consumption, diet, and lifestyle between 1999 and 2002. Polytomous logistic regression models were used to estimate the association between organic food consumption, and lifestyle, socio-demographics, and dietary habits.

This cross-sectional study uses data from the Danish Diet, Cancer and Health cohort.

A total of 43,209 men and women aged between 54 and 73 years were included in the study.

Overall, 15% reported never consuming organic food, 39% had low organic food consumption, 37% had medium organic food consumption and 10% had high organic food consumption. The relative risk of consuming organic food versus never consuming organic food was highest among women, persons with body mass index <25 kg/m2, persons with low alcohol intake, persons participating in sports, persons who did not smoke or were former smokers, and among persons who adhered to the Danish national dietary guidelines. Associations were more distinct with higher levels of organic food consumption.

Based on a historical cohort of Danish adults, organic food consumption was associated with a generally healthy lifestyle, more favorable socio-demographics, and dietary habits. These findings have to be considered in the adjustment strategy for future studies linking organic food consumption with health outcomes.

We investigated the association of dietary Mg intake with insulin resistance and markers of endothelial function among Iranian women.

A cross-sectional study.

Usual dietary intakes were assessed using a validated FFQ. Dietary Mg intake was calculated by summing up the amount of Mg in all foods. A fasting blood sample was taken to measure serum concentrations of glycemic indices (fasting plasma glucose and insulin) and endothelial function markers (E-selectin, soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1). Insulin resistance and sensitivity were estimated using the Homeostasis Model Assessment-Insulin Resistance (HOMA-IR), Homeostasis Model Assessment β-cell function (HOMA-β) and quantitative insulin sensitivity check index (QUICKI).

Iranian female nurses (n 345) selected by a multistage cluster random sampling method.

The Mg intake across energy-adjusted quartiles was 205 (se 7), 221·4 (se 8), 254·3 (se 7) and 355·2 (se 9) mg/d, respectively. After adjustments for potential confounders, QUICKI level was significantly different across quartiles of Mg intake (Q1: 0·34 (se 0·02), Q2: 0·36 (se 0·01), Q3: 0·40 (se 0·01), and Q4: 0·39 (se 0·02), P = 0·02); however, this association disappeared after considering markers of endothelial function, indicating that this relation might be mediated through endothelial dysfunction. After controlling for all potential confounders, Mg intake was inversely, but not significantly, associated with serum concentrations of sICAM (Q1: 239 (se 17), Q2: 214 (se 12), Q3: 196 (se 12), and Q4: 195 (se 17), P = 0·29). There was no other significant association between dietary Mg intake and other indicators of glucose homoeostasis or endothelial markers.

Higher dietary Mg intake was associated with better insulin sensitivity in Iranian females. This linkage was mediated through reduced endothelial dysfunction.

This study examined Na intake and identified the major food sources of Na in healthy Chinese adults aged ≥50 years in Hong Kong.

Participants who completed a baseline assessment of a randomised controlled trial assessing the effectiveness of exercise and nutrition supplementation on improving physical and cognitive functions were included. A single 24-h urine sample and a 3-d diet record were used to measure urinary Na excretion and dietary intake, respectively. The compliances to the WHO (<5 g/d) and China Nutrition Society (<6 g/d) recommendations for salt intake were assessed based on the urinary Na excretion. The relative contribution of sixteen food groups to the dietary Na intake was expressed as percentages. Associations between food groups and urinary Na excretion were analysed using multiple linear regression.

Community facilities.

Totally, 114 healthy Chinese adults (mean age 60·6 years, 55 % women).

The mean urinary Na excretion over 24-h was 2876·6 ± 1249·4 mg/d (7·3 ± 3·2 g salt/d). Overall, 22·8 % of participants met the WHO recommendation and 34·2 % met the Chinese Nutrition Society recommendation for salt intake. The major food sources of dietary Na intake were condiments (42·4 %), cereals and their products (16·8 %) and soups (13·5 %). Higher intakes of seafood and nuts were associated with lower urinary Na excretion.

Public health strategies should target healthy Chinese adults in Hong Kong to modify the current patterns of Na intake. Targeting condiments, cereals and their products and soups will be an important strategy to reduce their Na intake.

To present an overview of how artificial intelligence (AI) could be used to regulate eating and dietary behaviours, exercise behaviours and weight loss.

A scoping review of global literature published from inception to 15 December 2020 was conducted according to Arksey and O’Malley’s five-step framework. Eight databases (CINAHL, Cochrane–Central, Embase, IEEE Xplore, PsycINFO, PubMed, Scopus and Web of Science) were searched. Included studies were independently screened for eligibility by two reviewers with good interrater reliability (k = 0·96).

Sixty-six out of 5573 potential studies were included, representing more than 2031 participants. Three tenets of self-regulation were identified – self-monitoring (n 66, 100 %), optimisation of goal setting (n 10, 15·2 %) and self-control (n 10, 15·2 %). Articles were also categorised into three AI applications, namely machine perception (n 50), predictive analytics only (n 6) and real-time analytics with personalised micro-interventions (n 10). Machine perception focused on recognising food items, eating behaviours, physical activities and estimating energy balance. Predictive analytics focused on predicting weight loss, intervention adherence, dietary lapses and emotional eating. Studies on the last theme focused on evaluating AI-assisted weight management interventions that instantaneously collected behavioural data, optimised prediction models for behavioural lapse events and enhance behavioural self-control through adaptive and personalised nudges/prompts. Only six studies reported average weight losses (2·4–4·7 %) of which two were statistically significant.

The use of AI for weight loss is still undeveloped. Based on the current study findings, we proposed a framework on the applicability of AI for weight loss but cautioned its contingency upon engagement and contextualisation.

To examine associations between diet and risk of developing gastro-oesophageal reflux disease (GERD).

Prospective cohort with a median follow-up of 15·8 years. Baseline diet was measured using a FFQ. GERD was defined as self-reported current or history of daily heartburn or acid regurgitation beginning at least 2 years after baseline. Sex-specific logistic regressions were performed to estimate OR for GERD associated with diet quality scores and intakes of nutrients, food groups and individual foods and beverages. The effect of substituting saturated fat for monounsaturated or polyunsaturated fat on GERD risk was examined.

Melbourne, Australia.

A cohort of 20 926 participants (62 % women) aged 40–59 years at recruitment between 1990 and 1994.

For men, total fat intake was associated with increased risk of GERD (OR 1·05 per 5 g/d; 95 % CI 1·01, 1·09; P = 0·016), whereas total carbohydrate (OR 0·89 per 30 g/d; 95 % CI 0·82, 0·98; P = 0·010) and starch intakes (OR 0·84 per 30 g/d; 95 % CI 0·75, 0·94; P = 0·005) were associated with reduced risk. Nutrients were not associated with risk for women. For both sexes, substituting saturated fat for polyunsaturated or monounsaturated fat did not change risk. For both sexes, fish, chicken, cruciferous vegetables and carbonated beverages were associated with increased risk, whereas total fruit and citrus were associated with reduced risk. No association was observed with diet quality scores.

Diet is a possible risk factor for GERD, but food considered as triggers of GERD symptoms might not necessarily contribute to disease development. Potential differential associations for men and women warrant further investigation.
