Abstract Background and aims While excess energy intake and physical inactivity constitute the obvious causes of body fat accumulation, persistent organic pollutants (POPs) are novel factors that have been linked to cardiometabolic disorders. Major sources of POPs are animal fats including fatty fish. Given the putative protective effects of fish on cardiovascular disease, we explored whether high consumption of fatty fish increased serum concentrations of POPs. Methods and results Men and women...

Objectives To identify if maternal educational attainment is a prognostic factor for gestational weight gain (GWG), and to determine the differential effects of lifestyle interventions (diet based, physical activity based or mixed approach) on GWG, stratified by educational attainment. Design Individual participant data meta-analysis using the previously established International Weight Management in Pregnancy (i-WIP) Collaborative Group database (https://iwipgroup.wixsite.com/collaboration). Pr...

Weight loss diets affect food choices and control of eating. We evaluated the effects of intermittent energy restriction (IER) vs. continuous energy restriction (CER) on nutritional composition and eating behavior. Individuals with BMI 30–45 kg/m2, abdominal obesity and ≥1 additional metabolic syndrome component were randomized to IER vs. CER with similar energy restriction. Of 112 participants, 98 completed weighed dietary records and the Three Factor Eating Questionnaire at baseline and three ...

Background: High dietary intake or blood concentrations (as biomarkers of dietary intake) of vitamin C, carotenoids and vitamin E have been associated with reduced risk of cardiovascular disease, cancer and mortality, but these associations have not been systematically assessed. Objective: We conducted a systematic review and meta-analysis of prospective studies of dietary intake and blood concentrations of vitamin C, carotenoids, and vitamin E in relation to these outcomes. Design: We searched ...

Abstract Background and aims Persons with “metabolically healthy” obesity may develop cardiometabolic complications at a lower rate than equally obese persons with evident metabolic syndrome. Even morbidly obese individuals vary in risk profile. Persistent organic pollutants (POPs) are widespread environmental chemicals that impair metabolic homeostasis. We explored whether prevalence of metabolic syndrome in morbidly obese individuals is associated with serum concentrations of POPs. Methods and...

Abstract Background & aims Long-term adherence to conventional weight-loss diets is limited while intermittent fasting has risen in popularity. We compared the effects of intermittent versus continuous energy restriction on weight loss, maintenance and cardiometabolic risk factors in adults with abdominal obesity and ≥1 additional component of metabolic syndrome. Methods & results In total 112 participants (men [50%] and women [50%]) aged 21–70 years with BMI 30–45 kg/m2 (mean 35.2 [SD 3.7]) wer...

Importance Quitting smoking is enhanced by the use of pharmacotherapies, but concerns have been raised regarding the cardiovascular safety of such medications. Objective To compare the relative cardiovascular safety risk of smoking cessation treatments. Design, Setting, and Participants A double-blind, randomized, triple-dummy, placebo- and active-controlled trial (Evaluating Adverse Events in a Global Smoking Cessation Study [EAGLES]) and its nontreatment extension trial was conducted at 140 mu...
