Abstract

Objective

To study the relationship between cesarean Delivery (CD) and overweight in preschool children, considering the presence of birth aspects and demographic characteristics that have been associated with the risk of excess weight.

Methods

This retrospective cross-sectional analysis used representative data of children from 2 to 6 years of age at municipal daycare centers in Taubaté, São Paulo, Brazil. The sample included 752 preschoolers. Weight and height were collected in daycare centers, and the nutritional status classification was performed using z scores of Body Mass Index (zBMI). Data analysis was performed in the bivariate and multivariate manner, the latter with the inclusion of another possible risk factor. Adjustments were made for daycare centers time, sex, birth length and weight and maternal schooling.

Results

The mean age of preschool children was 4.7 years, and 53.8% were boys. The prevalence of overweight children was 21.7%. The median zBMI of the children born by CD was higher than that of vaginal Delivery (p = 0.0194). The prevalence of overweight showed association with CD (p = 0.0196; PR = 1.397 with 95% CI of 1065–1831). Logistic binary multivariate regression analysis confirmed the association, even in the presence of other possible risk factors (CR: 1.580, 95% CI: 1.072–2.330).

Conclusion for Practice

Birth by CD is one of the factors that are associated with the early development of overweight in preschoolers.
