Material: This cross‐sectional study included 1273 children, from Chile (n = 496), Colombia (n = 340), and Spain (n = 437). The sociodemographic information together with the lifestyle and health markers of the children were measured. There was an inverse association between a low or medium‐low socioeconomic level for the parents of Chilean children and handgrip strength (β −0.61, p < 0.001); meanwhile, for Spanish children, an inverse association between a low or medium‐low socioeconomic level and PA after school (β −0.58, p = 0.016), lifestyle (β −0.74, p = 0.015), and with MD adherence (β −0.86, p = 0.004) was found. The risk (i.e., by odd ratios (OR)) of being divorced/separated parents marital status showed an inverse association with abdominal obesity (OR 0.21, p = 0.045) in Spanish children; however, the parent’s marital status and a low educational level were risk factors for the suffering of a low nutritional level in Colombian children (OR 2.02, p = 0.048; OR 2.49, p < 0.001, respectively). On the other hand, a low educational level for parents reported for Chilean children had a positive association with ST of ≥4 h per day (OR 1.82, p = 0.020). In conclusion, in Spanish‐speaking children, the lifestyle and health markers of the children are affected by the sociodemographic background of their parents; however, these effects could be moderated by the socio‐cultural and economic status of their countries as members of the OCDE; therefore, it is essential to develop policies that decrease these gaps, so that children who are under‐resourced can reach their full potential.
