In addition, maternal education ≥ seven years was also positively associated with their children’s overweight (PR 1.45; p < 0.01). Children born

weighing ≥ 3.9 kg showed a 14.2% prevalence of overweight at the time of the survey, representing a frequency of overweight 64% higher than those children whose birth weight was < 3.9 kg (p < 0.01). Similar prevalence and PR were observed among children who consumed soft drinks or artificial juices or fried foods on at least four days per week. However, when considering Selleck PD-332991 the preschoolers who consumed soft drinks or sugary drinks and fried foods on four or more days per week, a synergistic association was identified with the increased prevalence and strength of association with overweight, which, however, was not maintained in the multivariate analysis. Being an only child or having only one sibling, when compared to those children with two or more siblings, showed a PR of 1.77 (p = 0.000). The number of TV sets in the home was also associated with higher prevalence of overweight, identifying as a risk group the homes where there were two or more TV sets (PR 1.44, p < 0.05). When comparing children who received EBF for a period < 150 versus ≥ 150 days, the former had a 30% higher PR (p < 0.10). In the analysis according to the hierarchical

level between risk factor and overweight (Table 3), it was observed that http://www.selleckchem.com/products/JNJ-26481585.html the following remained in the macro-environmental multivariable model (model 1): socioeconomic class C (PR 1.42 [95% CI: 1.08 to 1.86]) and regions S and SE (PR 1.63 [95% CI: 1.25 to 2.12]); regarding model 2, maternal education ≥ seven years (PR 1.50 [95% CI: 1.15 to 1.97]) and obesity (PR 1.87 [95%CI: 1.39 to 2.52]). Among the seven individual variables chosen for model 3, three remained in the multivariate model of individual factors: birth weight ≥ 3.9 kg (PR 1.91 [95% CI: 1.35 to 2.72]), being an only child or to having

for only one sibling (PR 1.85 [95% CI: 1.35 to 2.55]), and consumption of soft drinks or artificial juices four or more times a week (PR 1.36 [95% CI: 1.03 to 1.79]). When the three previous models were grouped (model 4), maternal education and the consumption of soft drinks or artificial juices did not maintain the association. However, macro-regions S and SE, economic class C, maternal obesity, birth weight > 3.9 kg, and number of siblings ≤ one were independently associated with overweight in Brazilian preschoolers in PNDS 2006/07. A previous publication showed that the increased prevalence of overweight among children younger than five years of age that occurred between 1989 and 2006 was due to overweight increase among preschoolers, as the prevalence among infants decreased.
