Aggregation of behavioral risk factors to noncommunicable chronic diseases: A national school-based study with Brazilian adolescents.

There is an increasing interest in the study of the aggregation of risk factors for noncommunicable chronic diseases. However, there are no studies among adolescents stratified by alcohol use. This study investigated the aggregation of cardiovascular risk factors in adolescents considering the use or not of alcohol.

Lower inter-partum interval and unhealthy life-style factors are inversely associated with n-3 essential fatty acids changes during pregnancy: a prospective cohort with Brazilian women.

Objective: To analyze serum fatty acids concentrations during healthy pregnancy and evaluate whether socioeconomic, demographic, obstetric, nutritional, anthropometric and lifestyle factors are associated with their longitudinal changes.

Study Design: A prospective cohort of 225 pregnant women was followed in the 5th-13th, 20th-26th and 30th-36th weeks of gestation. Serum samples were collected in each trimester of pregnancy and analyzed to determine the fatty acids composition using a high-throughput robotic direct methylation method coupled with fast gas-liquid chromatography.

C-reactive protein and later preeclampsia: systematic review and meta-analysis taking into account the weight status.

Objectives: This study aims to determine whether high C-reactive protein (CRP) concentration during pregnancy is associated with later preeclampsia and whether weight status (BMI) is a potential modifier of the relation between CRP and preeclampsia.

Methods: Twenty-three studies were included in a systematic literature review and a subset of 18 in a meta-analysis. Weighted mean difference (WMD) [with their 95% confidence intervals (CI)] of CRP in preeclampsia and control groups was the estimator.
