Objective: To investigate whether breastfeeding in early life affects blood pressure of preschoolers., Methods: Cross-sectional study nested in a cohort from a municipality in the state of Minas Gerais, Brazil. All children in the cohort were invited for this study. Thus, between 2009 and 2010, blood pressure of 230 preschool children and their mothers, in addition to anthropometric variables, previous history, and socioeconomic status were evaluated. Blood pressure measurement was assessed in the morning, using automatic Omron ® HEM-714INT and HEM-781INT devices to measure the blood pressure of preschool children and their mothers, respectively. Logistic regression was used to study the association between breastfeeding and blood pressure. The significance level was set at 5%., Results: This study identified 19 (8.26%) preschool children with high blood pressure (values above the 90th percentile). High systolic blood pressure was associated with low birth weight (OR=5.41; 95% CI=1.45-20.23) and total breastfeeding duration of less than six months (OR=4.14; 95% CI=1.40-11.95). High diastolic blood pressure was not associated with any variable, whereas high systolic blood pressure/diastolic blood pressure ratio was associated with breastfeeding duration of less than six months (OR=3.48; 95% CI=1.34-9.1)., Conclusion: The results of this study indicate that preschoolers breastfed for a period of less than six months were more likely to have high blood pressure when compared to those breastfed for a longer period, suggesting a protective effect of breastfeeding against high blood pressure in this population., (Copyright © 2016 Sociedade Brasileira de Pediatria.

Objective: To investigate the determinants of dyslipidemia in preschoolers., Methods: A total of 227 preschoolers residing in an urban area of the city of Diamantina, Minas Gerais, Brazil were evaluated at age 5 years, using a cross-sectional design. Dietary intake from a food frequency questionnaire, anthropometric/biochemical parameters, and socioeconomic/behavioral information from a questionnaire were evaluated. 'Mixed diet', 'snack', and 'unhealthy' dietary patterns were identified using principal component analysis. The determinants of dyslipidemia were examined using Poisson regression analysis., Results: The prevalence of dyslipidemia in this study was 65.19%. Preschoolers who less frequently consumed foods in the 'mixed diet' dietary pattern had a higher risk of high concentrations of low-density lipoprotein cholesterol (PR=2.30; p=0.004) when compared with those with more frequent consumption of the 'mixed diet' dietary pattern. Preschoolers whose mothers had lower levels of education presented a lower risk of high concentrations of low-density lipoprotein cholesterol (PR=0.43; p=0.003), and preschoolers who were overweight/obese presented with greater risk of high concentrations of low-density lipoprotein cholesterol (PR=2.23; p=0.003)., Conclusion: The determinants of dyslipidemia identified in this study were less frequent consumption of foods in the 'mixed diet' dietary pattern, higher body mass index, and lower level of maternal education. This study shows that despite the young age of the group under study, they already present a high prevalence of dyslipidemia, which is an important risk factor for cardiovascular disease., (Copyright © 2013 Sociedade Brasileira de Pediatria.

Objectives: To identify dietary patterns in pre-school children and to investigate its determinants., Methods: Cross-sectional study nested in a cohort born between 2004 and 2005 in the municipality of Diamantina, state of Minas Gerais, Brazil. The instrument used to explore the dietary patterns was a frequency questionnaire for food consumption. Factor analysis was used for the identification of the dietary patterns. The study also assessed personal and socioeconomic data and anthropometric measurements of 232 preschoolers in the period between July 2009 and July 2010. The determinants of food patterns were identified by logistic regression., Results: Three patterns were obtained, which were called: "mixed diet," "snack," and "unhealthy." The children of mothers with low education are more likely (odds ratio - OR = 3.80; confidence interval 95% - 95%CI = 1.90-7.60) to consume food from the "mixed diet" pattern, and less likely (OR = 0.31; 95%CI = 0.15-0.61) to consume food from the "snack" pattern, while those with higher per capita income are more likely to consume food from the "unhealthy" pattern (OR = 2.43; 95%CI = 1.13-5.24)., Conclusion: Three dietary patterns were identified in the studied population, which were determined by the level of maternal education and per capita income.
