title: Association between socioeconomic vulnerability and height with obesity in low-income Chilean children in the transition from preschool to first grade.
abstract: This study determined the percentage of obesity among lower-income Chilean children 4-6 years of age, by socioeconomic vulnerability (family score assessing the children's risk of becoming poor) and height. The sample included 17,080 children with anthropometry at 4, 5, and 6 years of age, and three categories of socioeconomic vulnerability. Body mass index Z-score (BMI Z), % obesity, height/age Z-score (HAZ) by socioeconomic vulnerability/sex, the effect of socioeconomic vulnerability on BMI Z and HAZ by age/sex, and BMI Z and % obesity at 4-6 years, according to initial height, were determined. Between 4-6 years, % obesity is very high, especially among the less-vulnerable and taller children. Preventive measures should prioritize this group.
