We evaluated their independent and combined effects on cardiometabolic outcomes. This prespecified secondary analysis of a 2 × 2 factorial randomised controlled trial assigned 131 women with overweight or obesity (median BMI 30·7 kg/m2; age 18-45 years) to TRE, HIIT, TRE + HIIT or control for 7 weeks. TRE limited daily intake to a ≤10-hour eating window; HIIT comprised three supervised treadmill sessions weekly. The primary analysis followed the intention-to-treat principle after multiple imputation; linear mixed-effects models estimated TRE and HIIT main effects and their interaction, with Holm-Bonferroni-adjusted interaction p-values; per-protocol sensitivity analyses excluded dropouts. No significant TRE × HIIT interaction was detected. In intention-to-treat main-effect analyses, TRE reduced body weight (-3·36 kg, p = 0·008), fat mass (-1·53 kg, p = 0·025) and visceral fat area (-12·82 cm2, p < 0·001), but also reduced muscle mass (-0·80 kg, p = 0·020) and modestly lowered HDL-C. HIIT main effects were minimal in the intention-to-treat analysis, while per-protocol sensitivity analyses suggested reductions in BMI, fat mass, total cholesterol, LDL-C and HbA1c, although these findings are more susceptible to attrition bias. Within the constraints of limited power and short duration, no interaction between TRE and HIIT was detected. TRE-related adiposity benefits should therefore be weighed against concurrent reductions in muscle mass and changes in lipid profiles. Larger, adequately powered, longer-term trials are needed to confirm these findings and clarify their clinical relevance.Trial registration: NCT04019860.","PeriodicalId":9257,"journal":{"name":"British Journal of Nutrition","volume":" ","pages":"1-10"},"PeriodicalIF":3.1,"publicationDate":"2026-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149036574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants with the Patient Health Questionnaire (PHQ-9) scores ≥5 were defined as having depressive symptoms. Total Ca intake was defined as the sum of dietary Ca and Ca supplements, estimated through the first 24-h dietary recall, and was grouped into four ranges [Q1 (≤606·5 mg/day), Q2 (606·5-962·5 mg/day), Q3 (962·5-1476·0 mg/day) and Q4 (>1476·0 mg/day)] according to quartiles.

In this study, 25·6 % of participants showed depressive symptoms, with moderate to severe depressive symptoms accounting for 9·7 % among all participants. After adjusting for all relevant confounding variables, compared with Q1, the odds of depressive symptoms in Q3 and Q4 were 40 % lower (OR:0·60, 95 % CI: 0·40,0·89) and 44 % lower (OR: 0·56, 95 % CI: 0·35,0·89), respectively (Pfor trend = 0·003). RCS further depicted the negative association between total Ca intake and depressive symptoms. Higher estimated total Ca intake was associated with lower odds of depressive symptoms among US adult cancer survivors.

Household food insecurity was assessed using the Household Food Insecurity Access Scale (HFIAS), dietary intake via the Semi-quantitative Food Frequency Questionnaire (SQ-FFQ) and anaemia defined as Hb <10·5 g/dL.

The objective of this research was to investigate the relationship between dietary flavanones and the prevalence of kidney stones among adults in the USA. Flavanones, including eriodictyol, hesperetin and naringenin, were sourced from the National Health and Nutrition Examination Survey (NHANES) conducted between 2007-2010 and 2017-2018, utilising two 24-h dietary recall interviews. The definition of kidney stones was established through a self-administered questionnaire. To evaluate the relationships between dietary flavanones and kidney stones, a variety of statistical methods were utilised, such as multivariable regression analysis, restricted cubic splines (RCS) and subgroup analysis. Data from 9790 participants were included in this analysis, with 9·67 % of them indicating that they had experienced kidney stones. After adjusting for potential confounding factors, it was found that kidney stones exhibited a negative correlation with total flavanones and naringenin, with OR of 0·96 (95 % CI 0·93, 1·00) and 0·89 (95 % CI 0·80, 0·99) for the highest intake group compared with the lowest intake group. The RCS plot revealed a notable negative linear association between the consumption levels of total dietary flavanones and the risk of kidney stones, including naringenin. The results of the subgroup analysis indicated that no significant interactions were observed in each subgroup. Our research indicated that a higher intake of flavanones correlates with a lowered prevalence of kidney stones in adults.","PeriodicalId":9257,"journal":{"name":"British Journal of Nutrition","volume":" ","pages":"613-623"},"PeriodicalIF":3.1,"publicationDate":"2026-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147811424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to investigate the association between serum ketone levels and MetS and to examine how genetic and lifestyle factors influence this relationship. We conducted a cross-sectional observational study using data from the UK Biobank, comprising 269 178 participants. Participants were categorised into low and high serum ketone groups based on β-hydroxybutyrate levels (cut-off: 0·12 mM). Dietary patterns were assessed using validated questionnaires, and a polygenic risk score (PRS) was generated to examine genetic influences on ketone metabolism. Individuals with higher ketone levels showed significantly lower MetS prevalence, with reduced BMI, waist circumference, TAG and glucose levels, alongside higher HDL-cholesterol. These individuals also exhibited distinct dietary patterns, characterised by lower carbohydrate (CHO) and higher fat intake, as well as increased physical activity. The PRS was inversely associated with MetS risk, particularly for abdominal obesity, TAG and HDL-cholesterol components. Notably, PRS modified the relationship between plant-based diet and ketone levels, with stronger positive associations observed in individuals with higher PRS. However, a high CHO diet showed weaker associations with PRS. In conclusion, genetic predisposition influenced ketone metabolism and its protective association with MetS risk. The interaction between genetic predisposition and lifestyle factors has crucial clinical implications for developing personalised dietary and lifestyle interventions. This research provides evidence for individualised approaches to optimise metabolic health through targeted ketone metabolism modulation, which could inform precision medicine strategies for MetS prevention and management.","PeriodicalId":9257,"journal":{"name":"British Journal of Nutrition","volume":" ","pages":"592-606"},"PeriodicalIF":3.1,"publicationDate":"2026-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147763236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: To determine the prevalence of overweight and obesity among university students in Vietnam and identify associated socio-demographic and behavioural factors. Methods: A cross-sectional study was conducted among 2000 students from ten universities across Northern, Central and Southern Vietnam. Anthropometric measurements were collected using standardised procedures. Overweight and obesity were diagnosed according to the WHO recommendations for Asian populations, with a cut-off of BMI ≥ 23 kg/m2. Multivariable logistic regression was performed to examine factors independently associated with overweight and obesity. Results: Among 2000 students, 25·5 % were overweight or obese (12·3 % overweight and 13·2 % obese), with prevalence significantly higher in males than females (35·1 % v. 17·5 %, P < 0·001). Regional differences were observed, with underweight more common in Central Vietnam and overweight and obesity most prevalent in the South, P < 0·05. Multivariable analysis showed significant associations between overweight or obesity and male sex (OR = 2·8), ethnic minority status (OR = 1·7), Southern residence (OR = 1·9), high waist:hip ratio (OR = 4·2) and being married (OR = 3·2).

Given the lack of prospective epidemiological cohort studies exploring the relationship between maternal 25(OH)D and fetal growth and adiposity, the aim of this study was to evaluate the association of maternal 25(OH)D concentrations with fetal biometry and adiposity at three periods of pregnancy. This prospective study included 330 women participating in the Araraquara Cohort Study, Brazil, who were evaluated at gestational ages ≤19, 20-28 and ≥30 weeks. 25(OH)D concentrations were measured by chemiluminescence. The following fetal outcomes were assessed by ultrasound: biometric (estimated fetal weight, femur length, abdominal circumference, head circumference and biparietal diameter) and adiposity parameters (subcutaneous tissue of the abdomen and subcutaneous areas of the thigh and arm). Generalised estimating equation models adjusted for maternal sociodemographic, lifestyle, nutritional, clinical and biochemical factors were used. In the unadjusted analysis, 25(OH)D ≥ 75 nmol/l was associated with higher fetal biometry and adiposity measures. After adjusting for potential confounders, for each increase of 10 nmol/l in 25(OH)D, there was a 0·0046 cm increase in fetal head circumference (β = 0·0046 [95 % CI 0·0003, 0·0089]; p = 0·04).

Thus, this study examines the distribution of energy and nutrient intakes across meals and snacks among primary schoolchildren aged 6·0-12·9 years in Peninsular Malaysia and the implications of meal skipping on their nutritional status. Data from 1102 children in Peninsular Malaysia from the South East Asian Nutrition Surveys (SEANUTS) II were analysed. Children's height, weight and waist circumference were measured. Questionnaires captured sociodemographic information and meal consumption patterns. Nutrient distribution across meals and snacks was assessed through a 1-d 24-h dietary recall approach. Logistic regression analysed the association between meal skipping and nutritional status. Breakfast contributed significantly to essential micronutrients but provided the least energy and macronutrients compared with lunch and dinner. Approximately one-third of daily nutrient intake came from snacking, with contributions ranging from 25 % for cobalamin to 36 % for both Ca and thiamine. Children who skipped main meals had higher odds of being overweight/obese (skipped one type of meal at least once weekly (1·59; 95 % CI (1·08, 2·33)); skipped > 1 type of meal (1·77; 95 % CI (1·12, 2·79)) and abdominal obese (skipped > 1 type of meal (1·91; 95 % CI (1·17, 3·12))). In conclusion, primary schoolchildren in Peninsular Malaysia tended to have higher micronutrient intakes at breakfast and higher energy and macronutrients in subsequent main meals. Meal skipping was linked to elevated body fat. This study underscores the need to prioritise continued education on the importance of healthy dietary habits among children.","PeriodicalId":9257,"journal":{"name":"British Journal of Nutrition","volume":" ","pages":"632-639"},"PeriodicalIF":3.1,"publicationDate":"2026-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147763152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
