Prevalence of Excess Sodium Intake and Their Corresponding Food Sources in Adults from the 2017-2018 Brazilian National Dietary Survey.

Excessive sodium intake has been related to high blood pressure, a central risk factor for cardiovascular disease. In the present work, updated estimates of sodium intake, the main food sources, and the prevalence of excessive intakes in a nationwide multi-ethnic sample of Brazilian adults (2017-2018 Brazilian National Dietary Survey) were presented. Based on two 24-h recalls adjusted for the within-person variation, the overall median of sodium intake was 2432 mg.

A chrononutrition perspective of diet quality and eating behaviors of Brazilian adolescents in associated with sleep duration.

It is well recognized that sleep and food intake exhibit 24-h patterns and disturbances of these patterns can lead to health problems. Cross-sectional and prospective studies suggest that diet quality and eating behaviors are negatively affected by short sleep duration. Adolescence is a particularly vulnerable period for the emergence of inadequate sleep and diet patterns.

Nutritional breakfast quality and cardiometabolic risk factors: Health Survey of São Paulo, a population-based study.

Objective: To evaluate the association between nutritional quality of breakfast and cardiometabolic risk factors.

Design: Cross-sectional study, 2015 Health Survey of São Paulo (2015 ISA-Capital) with Focus on Nutrition Study (2015 ISA-Nutrition).

Settings: Population-based study, with a representative sample of adults and elderlies living in São Paulo, Brazil.

Comparing Methods from the National Cancer Institute vs Multiple Source Method for Estimating Usual Intake of Nutrients in the Hispanic Community Health Study/Study of Latino Youth.

Background: The Multiple Source Method (MSM) and the National Cancer Institute (NCI) method estimate usual dietary intake from short-term dietary assessment instruments, such as 24-hour recalls. Their performance varies according to sample size and nutrients distribution. A comparison of these methods among a multiethnic youth population, for which nutrient composition and dietary variability may differ from adults, is a gap in the literature.

Healthful grain foods consumption by São Paulo residents: a 12-year analysis and future trends.

Objective: Understanding trends in grain consumption is essential to tackle the low consumption of healthful grain foods. This study aimed to evaluate trends and determinants of grain foods meeting the ≤10:1 carbohydrate:fibre ratio (≤10:1 ratio) in Brazil and to estimate this intake for the next years.

Design: Three editions of the cross-sectional, population-based study Health Survey of São Paulo (2003, 2008 and 2015).

Prevalence of consumption and nutritional content of breakfast meal among adolescents from the Brazilian National Dietary Survey.

Objective: To estimate the prevalence of breakfast consumption and describe the foods and nutrients consumed at this meal and throughout the day by Brazilian adolescents.

Method: A total of 7276 adolescents aged 10-19 years were evaluated in the Brazilian National Dietary Survey 2008-9, a population-based cross-sectional study. Individuals' information was collected at home.

Probability and amounts of yogurt intake are differently affected by sociodemographic, economic, and lifestyle factors in adults and the elderly-results from a population-based study.

The aim of this population-based cross-sectional health survey (N = 532) was to investigate the factors associated with the probability and amounts of yogurt intake in Brazilian adults and the elderly. A structured questionnaire was used to obtain data on demographics, socioeconomic information, presence of morbidities and lifestyle and anthropometric characteristics. Food intake was evaluated using two nonconsecutive 24-hour dietary recalls and a Food Frequency Questionnaire.

Sex differences in serum leptin and its relation to markers of cardiometabolic risk in middle-aged adults: evidence from a population-based study.

Objective: At elevated concentrations, circulating leptin has been associated with metabolic disturbances, namely insulin resistance, elevated blood pressure, inflammation, and endothelial dysfunction. Because women have higher leptin concentrations than men, it is possible that the effects of leptin on the metabolic profile are different between the sexes. The aim of this study was to investigate whether leptin is one of the key hormones to sex affect differences in the pathophysiology of cardiometabolic risk.

Children's nutrient intake variability is affected by age and body weight status according to results from a Brazilian multicenter study.

A major challenge in nutritional studies focusing on children is estimating "true" intake because the type and amount of foods eaten change throughout growth and development, thereby affecting the variability of intake. The present study investigated the hypothesis that age and body weight status affect the ratio of the within- and between-subject variation of intakes (VR) as well as the number of days of dietary assessment (D) of energy and nutrients. A total of 2,981 Brazilian preschoolers aged 1-6 years were evaluated in a cross-sectional study.

Are plasma homocysteine concentrations in Brazilian adolescents influenced by the intake of the main food sources of natural folate?

Background: Folate, a B vitamin, has been associated with a reduced concentration of plasma homocysteine (phcy), a marker of cardiovascular disease. The contribution of fruits and vegetables (FV) and other natural folate-rich foods to folate intake and folate status in Brazilian adolescents has hardly been determined.

Objectives: To investigate the intake of FV and beans and its association with the concentration of phcy in adolescents.
