The aim was to map evidence on the quality of records in the Mortality Information System (SIM) through a national scoping review of articles published up to April 2023 across five databases (PubMed, Embase, Scopus, LILACS, and SciELO). Studies focused on specific causes of death were excluded. Dimensions evaluated included accessibility, methodological clarity, coverage, completeness, reliability, consistency, non-duplication, timeliness, validity, and studies on ill-defined causes/garbage codes.

This investigation programme aims to: (1) describe maternal weight trajectories throughout the life course; (2) describe child weight, height and body mass index (BMI) trajectories; (3) create and validate models to predict childhood obesity at 5 years of age; (4) estimate the effects of prepregnancy BMI, gestational weight gain (GWG) and maternal weight trajectories on adverse maternal and neonatal outcomes and child growth trajectories; (5) estimate the effects of prepregnancy BMI, GWG, maternal weight and interpregnancy BMI changes on maternal and child outcomes in the subsequent pregnancy; and (6) estimate the effects of maternal food consumption and infant feeding practices on child nutritional status and growth trajectories.
Methods And Analysis: Linked data from four different Brazilian databases will be used: the 100 Million Brazilian Cohort, the Live Births Information System, the Mortality Information System and the Food and Nutrition Surveillance System.
Introduction: Cardiovascular disease is the main cause of general and premature death of adults aged 30-69 years in Brazil and around the world. Unhealthy food environments have been implicated as one of the factors associated with cardiovascular disease morbimortality because they affect people's health conditions and nutrition. This study aims to explore the association between unhealthy food environments (deserts/swamps) and premature cardiovascular disease mortality in the Brazilian population.

This review aimed to systematically assess the effects of computer-based interventions for the promotion of healthy eating on anthropometric indicators and food consumption of adolescents at school. Relevant scientific articles were searched in MEDLINE/PubMed, Embase, Scopus, Lilacs, PsycINFO and Cochrane Library/CENTRAL following the recommendations by PRISMA guide in August 2021. The quality and risk of bias in the studies were assessed by two reviewers independently.

The scope of this study was to analyze the temporal variation in the incidence of overweight and abdominal obesity among adolescents from public schools in a capital in northeastern Brazil. It is a study including information from three cross-sectional surveys carried out in 2001, 2009 and 2017, with 2,496 students aged 10 to 18 years of both sexes living in the city of Salvador, Bahia. Overweight was assessed using the Body Mass Index for Age (BMI/A) and abdominal obesity was assessed using waist circumference and waist-to-height ratio.

We estimated the prevalence of phenotypes combining these three markers and quantified the mortality risk associated with them.
Methods: Population-based cohort study using routine register-based linked data on all births and deaths in Brazil from January 1, 2011, to December 31, 2018.

Changes in food consumption, physical inactivity, and other lifestyle habits are potential causes of the obesity epidemic. Paradoxically, the media promotes idealization of a leaner body appearance. Under these circumstances, self-perception of weight by adolescents may be affected.

Objective: To estimate new case detection rates of leprosy among household contacts of patients with previously diagnosed leprosy and to investigate its associated risk factors.
Design, Setting, And Participants: This population-based cohort study included families registered in the 100 Million Brazilian Cohort linked with nationwide registries of leprosy; data were collected from January 1, 2007, through December 31, 2014.
There is a significant increase in overweight and obesity in adolescents worldwide. Here, we performed a cross-sectional study to examine the potential association between food consumption profiles and overweight in a large number of adolescents from Brazil. Sampling by clusters and conglomerates was carried out in students of public schools in Salvador, Brazil, between June and December 2009 and 1496 adolescents were evaluated.

Methods: Cross-sectional study with the participation of 1,176 students between the ages of 11 and 17 years old, in Salvador, Bahia, Brazil. The asthma symptoms were identified by using the standardized questionnaire from The International Study of Asthma and Allergies in Childhood Program (ISAAC), phase III.
Objective: To estimate factors associated with double burden of nutritional outcomes in the mother-child dyad at the household level (child stunting and/or maternal overweight).
Design: Cross-sectional study using the Brazilian Demographic and Health Survey. Nutritional outcomes were: mother with normal weight and child with normal height; overweight mother and child with normal height; mother with normal weight and short-stature child; and overweight mother and child with short stature (double burden).

Objective: This study identifies the risk factors for extreme weight-control behaviors among adolescents in public school in Salvador, northeastern Brazil.
Methods: A case-control study nested to a cross-sectional study, including 252 adolescents of both sexes, age between 11 to 17 years, with 84 cases and 168 age-matched controls was conducted.
