Pediatric overweight prevention through a parent training program for 2-4 year old Latino children.
BACKGROUND
Latino preschool children in the United States are at high risk for obesity. The objective of this study was to measure over a one-year period whether a parent training based on social learning theory combined with evidence-based interventions to promote optimal nutrition and physical activity will reduce the upward trend of BMI z-scores in groups of 2–4 year old Latino children living in low-income households.


METHODS
Seven weekly classes with 2 booster classes were delivered to low-income Latino parents with 2–4 year old children. A randomized controlled pilot study evaluated the effectiveness of the intervention that contrasts 61 children whose parents were randomized to receive Parent Training (PT) with 60 Wait-list (WL) subjects. Forty subjects did not attend the one-year follow up assessment, resulting in 81 subjects who have measurements for both baseline and one-year follow up assessments. To adjust for differential dropout rates and missing observations, imputation of missing data was done using a carefully constructed model that included relevant independent variables.


RESULTS
There were no significant subject differences between groups at baseline for family characteristics and BMI categories for child and parent. Children in the intervention group decreased their BMI z-scores significantly on average by .20 (SE= .08) compared to children in the control group who increased z scores on average by .04 (SE=.09) at one year (P<.05).


CONCLUSIONS
Parent training is effective to reduce the risk of overweight in preschool Latino children living in low-income households. The findings need to be examined in a larger sample of children.
