Review Meta AnalysisEffectiveness of universal multiple-risk lifestyle interventions in reducing depressive symptoms: Systematic review and meta-analysis.
Though many studies have explored the association between single-risk lifestyle interventions and depression, unhealthy lifestyle factors often co-occur, with adults engaging in two or more risk behaviours. To date, little is known about the effectiveness of universal multiple-risk lifestyle interventions to reduce depressive symptoms. We conducted a SR/MA to assess the effectiveness of universal multiple-risk lifestyle interventions (by promoting a healthy diet, physical activity and/or smoking cessation) to reduce depressive symptoms in adults. ⋯ The quality of evidence according GRADE was low. Although a small preventive effect was found, the substantial heterogeneity and RCTs with lower risk of bias suggested no effectiveness of universal multiple-risk lifestyle interventions in reducing depressive symptoms in a varied adult population. Further evidence is required.

Multicenter StudyPhysical activity rather than sedentary behaviour is socially determined in French adolescents with overweight and obesity.
Social differences in prevalence of overweight and obesity among adolescents, known as the weight social gradient, could be explained by differences in behaviours between social classes. This study examined the respective association of physical activity (PA), sedentary behaviour (SB) and weight status with adolescents' socioeconomic status. We used cross-sectional data for 1935 adolescents (13-18 years old) with overweight or obesity who participated in the PRALIMAP-INÉS (PRomotion de l'ALImentation et de l'Activité Physique - INÉgalités de Santé) trial conducted in northeastern France between 2012 and 2015. ⋯ PA was found an important factor of weight social gradient in adolescence. Actions aimed at preventing weight social inequalities among adolescents could include PA promotion as lever. CLINICAL TRIALS REGISTRY AND NUMBER: ClinicalTrials.gov (NCT01688453).

Adverse childhood experiences (ACEs) on mental disorders in young adulthood: Latent classes and community violence exposure.
Adverse childhood experiences (ACEs) have significant impacts on mental health outcomes. There is a growing interest in expanding the scope of ACEs beyond household environments. To date, few studies examine multidimensional ACEs with community violence. ⋯ However, the "household dysfunction" class was not significantly different in all three mental disorders from the "low adversity" class. Findings supported the differences in mental disorders in young adulthood by types of exposures to ACEs. The study highlights the importance of considering types of ACEs exposure for promoting mental health of young adults.

ReviewColorectal cancer screening using faecal occult blood tests for Indigenous adults: A systematic literature review of barriers, enablers and implemented strategies.
Colorectal cancer (CRC) screening using a Faecal Occult Blood Test (FOBT) is a well-established population intervention to reduce mortality and morbidity of CRC. As Indigenous people are not fully benefiting from the screening programs, a greater understanding of barriers and enablers affecting participation is needed. ⋯ The review identified barriers and possible enablers for Indigenous participation in the CRC screening program, some which appear to be unique to Indigenous people. Further intervention studies conducted in partnership with Indigenous communities are needed to improve participation.

Secondhand smoke exposure and higher blood pressure in children and adolescents participating in NHANES.
We assessed the relationship between acute and intermittent secondhand tobacco smoke (SHS) exposure with child and adolescent blood pressure (BP). We analyzed cross-sectional data from 3579 children and adolescents aged 8-17 years participating in the National Health and Nutrition Examination Survey (NHANES) collected between 2007 and 2012, with SHS exposure assessed via serum cotinine (a biomarker for acute exposures) and urine NNAL (4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol, a biomarker for intermittent exposures). BP percentiles and z-scores were calculated according to the 2017 guidelines established by the American Academy of Pediatrics. ⋯ For serum cotinine, an IQR increase was associated with 0.097 (95% CI: 0.020, 0.17) higher DBP z-scores, but was not significantly associated with SBP z-scores. The associations of cotinine and NNAL with BP also differed by sex. Our findings provide the first characterization of the relationship between a major tobacco-specific metabolite, NNAL, and BP z-scores in a nationally representative population of US children.
