The quantitative sociodemographic variables are presented as means (standard deviations) when they followed a parametric distribution and as medians (25th, 75th percentiles) when they followed a nonparametric distribution. The ranges are displayed after the semicolons. The qualitative variables are expressed as the absolute and relative frequencies (%). 1 Taking as reference the Olsen intrauterine growth curves [48]. 2 Taking as reference the World Health Organization (WHO)’s child growth standards [49].
