Early Determinants of Overweight and Obesity in Children Aged Under 2 Years in Mexico
Authors' conclusion
This study is one of the first in Mexico to analyse multiple risk factors simultaneously at the national level, as it had a representative sample of children under 2 years old. The findings underscore the importance of early intervention and a comprehensive approach considering family and socioeconomic factors in childhood obesity prevention.
