Insulin resistance (IR) is defined as the subnormal response to insulin action on its target tissues. Studies suggest that IR may increase the risk of hypertension, but the results are inconsistent and it is not known whether such an effect is independent of overweight/obesity. We aimed to evaluate the association between IR and the incidence of prehypertension and hypertension in the Brazilian population and whether this association is independent of overweight/obesity.

We investigated whether racial discrimination accelerates the weight and Body Mass Index (BMI) gain in Blacks and Browns participants of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) in four years of follow-up. We compared body weight and BMI between the 1st (2008-2010) and 2nd visit (2012-2014) of 5,983 Blacks and Browns participants. Exposure to racial discrimination and covariates (age, sex, education, and research center) were obtained at the 1st visit.

We evaluated data from 14,156 baseline participants of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) collected from 2008 to 2010, to analyze the effect modification of occupational social class on the association between sex and prevalence of type 2 diabetes. The crude and age-adjusted prevalence, according to sex and occupational social class, were estimated using generalized linear models with binomial distribution and logarithmic link function. This model was also used to estimate prevalence ratios (PR), adjusting for age group, race/skin color, and maternal education.

Background: It seems that the worst response to some classes of antihypertensive drugs, especially angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, on the part of the Black population, would at least partially explain the worse control of hypertension among these individuals. However, most of the evidence comes from American studies.

Objectives: This study aims to investigate the association between self-reported race/skin color and BP control in participants of the Longitudinal Study of Adult Health (ELSA-Brasil), using different classes of antihypertensive drugs in monotherapy.

Background: Job strain has been reported as a trigger for binge eating, yet the underlying mechanisms have been unclear. The aim of this study was to evaluate whether work-family conflict is a pathway in the association between job strain and binge eating, considering the possible effect-modifying influence of body mass index (BMI).

Methods: This cross-sectional analysis included 12,084 active civil servants from the multicenter Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

Blacks and Browns have major health disadvantages, are less likely to rise in the social hierarchy throughout the course of life, and pertain to lower socioeconomic levels than Whites as a result of structural racism. However, little is known about the mediating role of intergenerational mobility in the association between race/skin color and health. The aim of the present study was to investigate the association between racism and self-rated health and to verify to what extent intergenerational social mobility mediates this association.

Background: Life course epidemiology is a powerful framework to unravel the role of socioeconomic position (SEP) disparities in hypertension (HTN). This study investigated whether life course SEP is associated with HTN incidence. Specifically, to test whether cumulative low SEP throughout life and unfavorable intergenerational social mobility increased HTN incidence.

Article Synopsis
  • The study investigates glycemic regression among adults with newly diagnosed diabetes and intermediate hyperglycemia, finding that while regression is common, it often appears more favorable than it is when adjusting for regression to the mean (RTM).
  • Out of those with newly diagnosed diabetes, 49.4% showed partial or complete regression, but this dropped to 20.2% after accounting for RTM; similar reductions were noted for intermediate hyperglycemia, depending on the definition used.
  • Weight loss of at least 2.6% significantly improved chances of regression for both diabetes and intermediate hyperglycemia, highlighting the role of lifestyle changes in managing these conditions over time.

Background: This study investigated whether self-reported race/skin colour and perceived racial discrimination predict higher obesity incidence after approximately 4-year follow-up of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). We also investigated whether these associations are modified by educational level.

Methods: Following exclusion of individuals defined as obese (body mass index ≥30 kg/m) at baseline, associations between race/skin colour and obesity incidence between the first (2008-2010) and second (2012-2014) visits were investigated in 10 130 participants.
