Table 1Comparison of BMI, total body fat mass in the android region and waist circumference according to different practices of exclusive breastfeeding and consumption of other foods in the first 6 months of life of children from 4 to 7 years, Vi?osa, …In the bivariate meantime analyses between the variables of infant feeding and categorized parameters of nutritional status, total body fat percentage, fat percentage in the android region, and waist circumference, there were not significant associations (Table 2). There was one linear association between the EBF and the percentage of total body fat, with increase of the practice tending to increase of this percentage (Table 2).

Table 2Prevalence of BMI/A changes, percentage of total body fat, android region and waist circumference, and Crude odds ratio (confidence interval of 95%) according to different practices of exclusive breastfeeding and consumption of other foods in the first …In Tables Tables3,3, ,4,4, and and55 are the results of the association between the confounding factors and the outcomes of interest. Among the potential confounding factors considered in relation to the nutritional status of the children, an association statistically significant was shown in the bivariate analyses in the maternal prepregnancy BMI, gestational weight gain, and sex (Table 3). Further predominance of changes in BMI/A was observed in children whose mother had prepregnancy BMI 25kg/m2 (OR: 2,89; IC 95%: 1.18 to 7.09, P = 0.016) and had an excessive gestational weight gain (OR: 3,15; IC 95%: 1.41 to 7.06; P = 0.004).

Female children presented lower predominance of changes of nutritional status and less change to present these changes (OR: 0,33; IC 95%: 0.15 to 0.73, P = 0.005) (Table 3). In addition to these variables, there were variables: included in the multivariate analyses (P < 0,20) birth weight (P = 0,136), age (P = 0,088) (Table 3), mother's age (P = 0,197), income per capita (P = 0,147), and hours in school (P = 0,097) (Table 4).Table 3Prevalence of BMI/A Drug_discovery changes, percentage of total body fat, from android region and waist circumference, and Crude odds ratio (confidence interval of 95%) according to maternal, pregnancy and birth variables, sex, age, and occurrence of hospitalizations …
