Table 2 Anthropometric variables, biochemical data, and poverty index by the age group in males. Values are presented as the mean ± SE or median (1st quartile–3rd quartile). Data were analyzed by ANOVA or the Kruskal-Wallis test to compare variables among the three age groups. The D score was considered poor at ≥ 33.3%
