XbaI polymorphism in the APOB gene and its association with increased cholesterol in children and adolescents: Ouro Preto study.

Atherosclerotic vascular changes can begin during childhood, providing risk for cardiovascular disease (CVD) in adulthood. Identifiable risk factors such as dyslipidemia accelerate this process for some children. The apolipoprotein B (APOB) gene could help explain the inter-individual variability in lipid levels among young individuals and identify groups that require greater attention to prevent CVD.

Rotating shift work time is directly associated with excess body adiposity.

Objective: To analyze the association between changes in body adiposity and length of service on a schedule of rotating shifts.

Methods: The study was a cross-sectional investigation conducted during the years 2012, 2015, and 2018, involving individuals engaged in rotating shifts at a company involved in iron ore extraction situated within the Iron Quadrangle region of Minas Gerais and the southeastern region of Pará, Brazil. Sociodemographic and behavioral data were collected along with anthropometric parameters in order to calculate body mass index (BMI) and the waist-to-height ratio (WHtR).
