In this study, the EBF time and the consumption of other foods in the first six months of life did not configure as factors associated to these parameters, with no differences in the values of android fat mass and waist circumference between the groups and with no significant statistical selleck Sorafenib association with previous and subsequent changes to the control by the confounding factors. As demonstrated in this study, other researchers observed no significant association between breastfeeding and nutritional status and body composition. Huus et al. [23] evaluated children aged 5 years and observed that the practice of EBF held for a period less than 4 months was associated with obesity; however, in multivariate data analysis this association was not significant (OR = 1,22; IC 95%: 0,81-1,83; P = 0,341).

Novaes et al. [24], in the municipality of Vi?osa, MG Brazil, among children from 6 to 10 years of age, it was found that the duration of EBF was not associated with obesity (P = 0.713), defined as z-score >+2, and classified by WHO [35] after the adjustment by confounding factors related to the child and mother’s characteristics. Novotny et al. [50], evaluating 420 American children between 6 months and 10 years of age, despite finding a significant inverse association (P = 0.043) between total breastfeeding and BMI of children in the analyses adjusted for confounders (birth weight, age, sex, and mother’s education), report not having found association between the practice of exclusive breastfeeding and its duration with the BMI values, results are not presented in the study.

Toschke et al. [51], assessing body composition in children 9-10 years old by DEXA, observed that the longer duration of breastfeeding was associated significantly with reduced total fat mass (P < 0.001), which was attenuated in 59% after adjustment by confounding factors that were socioeconomic, gestational, birth, lifestyle, and feeding. There was an inverse association between duration of breastfeeding with BMI in the bivariate analysis (P < 0.001) but in the adjusted model this association was not maintained (P = 0.238). Burdette et al. [52] compared children who were 5 years of age breastfed or not and found no difference in the percentage of total body fat measured by DEXA (P = 0.170). Breastfeeding for a time above 12 months without the use of formula did not show association with lower GSK-3 overweight taxes (P = 0.
