Aim: To update a previous systematic review and meta-analyses about the effect of breastfeeding promotion interventions on child growth.
Methods: Studies evaluating the effect of any type of breastfeeding promotion intervention on child weight, length (or height) and weight/height (or BMI) were screened. Papers published between 2006 and 2014 were checked using the following databases: PubMed/MEDLINE, Embase, Cochrane Database of Systematic Reviews, Lilacs and SciELO.
Objective: To evaluate the association of birthweight and weight gain during different periods in childhood with the prevalence of hypertriglyceridemic waist phenotype (HWP).
Methods: In 1982, all hospitals births in Pelotas, South Brazil, were identified, and the 5914 liveborn were examined and their mothers interviewed. This population has been followed for several times.
Background & Aims: Lean mass (LM) is an important parameter in clinical outcomes, which highlights the necessity of reliable tools for its estimation. The adductor pollicis muscle thickness (APMT) is easily accessible and suffers minimal interference from the adjacent subcutaneous fat tissue.
Objective: To assess the relationship between the APMT and LM in a sample of Southern Brazilian adults.
Aim: This study was aimed at systematically reviewing evidence of the association between breastfeeding and performance in intelligence tests.
Methods: Two independent searches were carried out using Medline, LILACS, SCIELO and Web of Science. Studies restricted to infants and those where estimates were not adjusted for stimulation or interaction at home were excluded.

Brazil is one of the countries with the lowest intergenerational income mobility. This article aimed to analyze intergenerational income mobility in the 1982 Birth Cohort in Pelotas, Rio Grande do Sul State. Two methods were used, intergenerational income elasticity and quantile regressions, in order to measure heterogeneity in income mobility as a function of different levels of parents' past income.

Methods: Two independent literature searches were carried out using the MEDLINE, LILACS, SCIELO and Web of Science databases. Studies restricted to infants and those without an internal comparison group were excluded.
Objective: To systematically review the literature in order to identify an association between income and tooth loss in adults.
Methods: An electronic search was conducted on PubMed, Scopus, Embase, Web of Knowledge, Scielo and LILACS. Studies were included if they reported the relationship between socioeconomic status (assessed by income) and tooth loss (clinical examination or self-reported) among adults aged from 18 to 60-years-old.
While South Americans are underrepresented in human genomic diversity studies, Brazil has been a classical model for population genetics studies on admixture. We present the results of the EPIGEN Brazil Initiative, the most comprehensive up-to-date genomic analysis of any Latin-American population. A population-based genome-wide analysis of 6,487 individuals was performed in the context of worldwide genomic diversity to elucidate how ancestry, kinship, and inbreeding interact in three populations with different histories from the Northeast (African ancestry: 50%), Southeast, and South (both with European ancestry >70%) of Brazil.

The aim of this study is to compare the effects of droperidol and ondansetron on subarachnoid morphine-induced pruritus.
Methods: 180 ASA I or II patients scheduled to undergo cesarean sections under subarachnoid anesthesia combined with morphine 0.
Background: We examined the associations between socioeconomic trajectories from birth to adulthood and gestational age and birth size in the next generation, using linked data from two population-based birth cohorts carried out in a Brazilian city. By comparing socioeconomic trajectories of mothers and fathers, we attempted to identify-specific effects of maternal and paternal socioeconomic trajectory on offspring birth weight, birth length, head circumference and gestational age at birth.
Methods: 2 population-based birth cohort studies were carried out in 1982 and 2004 in Pelotas (Brazil); 156 mothers and 110 fathers from the earlier cohort had children in 2004.
OBJECTIVE To analyze physical activity during adolescence in participants of the 1993 Pelotas Birth Cohort Study, Brazil. METHODS Data on leisure time physical activity at 11, 15, and 18 years of age were analyzed. At each visit, a cut-off point of 300 min/week was used to classify adolescents as active or inactive.

METHODS In 2004-2005, the individuals belonging to the Pelotas birth cohort of 1982 were identified for a home interview. A total of 4,297 individuals were interviewed and 4,202 individuals were included in the study (follow-up rate of 77.

There is evidence that childhood obesity predisposes adult obesity and, thus, that obesity should be prevented as early as possible. Some studies have shown that breastfeeding is a protective factor against overweight and obesity while other studies have not found this association.

Few prospective studies are available, particularly from low and middle-income countries. This study was aimed at assessing the cross-sectional and prospective associations between physical activity and C-reactive protein (CRP) levels in males belonging to the 1982 Pelotas (Brazil) Birth Cohort Study.

Thus, the composition of the Brazilian population is mixed, and its ethnoracial classification is complex. Previous studies showed conflicting results on the correlation between genome ancestry and ethnoracial classification in Brazilians.

Methods: Sociodemographic, clinical and reported data on child respiratory health from the First National Survey of Indigenous People's Health and Nutrition in Brazil were collected for 6128 children. Prevalence of pneumonia was calculated for independent variables and hierarchical multivariate analyses were performed to assess associations.
Background: Globally, diarrhea is the second leading cause of death among children under five. In Brazil, mortality due to diarrhea underwent a significant reduction in recent decades principally due to expansion of the primary healthcare network, use of oral rehydration therapy, reduced child undernutrition, and improved access to safe drinking water. The First National Survey of Indigenous People's Health and Nutrition in Brazil, conducted in 2008-2009, was the first survey based on a nationwide representative sample to study the prevalence of diarrhea and associated factors among Indigenous children in the country.

Objective: To evaluate the effect of total breastfeeding, breastfeeding duration and type of breastfeeding at 3 months of age on bone mass at 18 and 30 years.
Study Design: A prospective, longitudinal study was conducted with two birth cohorts (1982 and 1993) in Pelotas, Southern Brazil. Measurements of bone mineral content (BMC) and bone mineral density (BMD) at 18 and 30 years of age were obtained by dual-energy X-ray absorptiometry (DXA).
Background: The goal of this study was to identify the effect of the change in body mass index (BMI) from childhood to adulthood on body image satisfaction at 23 years of age in members of the 1982 Pelotas Birth Cohort in Pelotas, RS, Brazil.
Methods: The study used data from the 1986 and 2004-5 follow-up studies. Body shape satisfaction was evaluated using the Stunkard scale.
Background: Breastfeeding has clear short-term benefits, but its long-term consequences on human capital are yet to be established. We aimed to assess whether breastfeeding duration was associated with intelligence quotient (IQ), years of schooling, and income at the age of 30 years, in a setting where no strong social patterning of breastfeeding exists.
Methods: A prospective, population-based birth cohort study of neonates was launched in 1982 in Pelotas, Brazil.

Methods And Results: In 1982, all births in the city of Pelotas, southern Brazil, were identified and those children (n = 5,914) whose families lived in the urban area of the city have been followed and evaluated at several time points. The cohort participants were evaluated in 2012-13, and IMT was measured at the posterior wall of the right and left common carotid arteries in longitudinal planes using ultrasound imaging.
