To identify the dietary patterns of children aged 4–7 years and verify their association with sociodemographic characteristics, lifestyle habits and exclusive breast-feeding (EBF).
A cross-sectional study nested within a cohort, performed with Brazilian children aged 4–7 years. The children were re-evaluated at age 4 to 7 years and food patterns were identified a posteriori through principal component analysis. The predictive variables were related to socio-economic characteristics, lifestyle habits and duration of EBF.
Viçosa, Minas Gerais, Brazil.
Representative sample of 403 children followed up by the Lactation Support Program from the Extension Program of the Universidade Federal de Viçosa during the first 6 months of life.
Five dietary patterns were identified: ‘Traditional’, ‘Unhealthy’, ‘Milk and chocolate’, ‘Snack’ and ‘Healthy’. Children who did not receive EBF until they were at least 4 months old had a higher adherence to the ‘Unhealthy’ and ‘Snack’ patterns, and older children also consumed more ‘Unhealthy’ foods. The highest income was associated with the highest consumption of foods of the patterns ‘Unhealthy’, ‘Milk and chocolate’ and ‘Healthy’.
In view of the results, we emphasize the importance of providing support and encouragement towards EBF in the first months of life, as it can positively influence lifelong eating habits.
To evaluate the ability of anthropometric measurements to identify excess android fat and to propose cut-off points for excess central adiposity in children, according to age and sex.
A cross-sectional study with children from a municipality of Minas Gerais, Brazil. Receiver-operating characteristic curve analyses were performed to evaluate waist circumference (WC), waist-to-height ratio (WHtR) and conicity index (C-index) in estimating excess android fat by dual energy X-ray absorptiometry (DXA).
Viçosa, Minas Gerais, Brazil.
Children aged 4–9 years (n 788).
Overweight prevalence was 29·1 % and android fat percentage was higher among girls. All central fat measurements were able to discriminate excess android fat in the age groups evaluated, especially WC and WHtR, with cut-off points showing good sensitivity and specificity overall.
Because these methods are easy to obtain and inexpensive, it is possible to use WC, WHtR and C-index in population surveys to evaluate central obesity. The proposed cut-off points showed satisfactory values of sensitivity and specificity and can be used in epidemiological studies.
