Objectives: This study examines weight loss strategies (eating, physical activity (PA), or both) adopted by overweight or obese (OWOB) parents and children in relation to age, income, gender, education, and race/ethnicity in a predominantly low-income and high minority sample. We also examine if OWOB parent-child dyads employed the same strategies to lose weight, and how these strategies vary by demographic variables.

Methods: Data was compiled from the New Jersey Childhood Obesity Study (NJCOB). A random digit dial household phone survey was used to select 1,708 households with at least one child aged 3-18 years from five cities in New Jersey. There were 231 OWOB parent-child dyads in this sample. Bivariate and multivariate analyses were performed to determine the demographic variables significantly associated with the type of weight loss strategy chosen.

Results: Males had higher odds of using PA and both eating and PA when compared to females. Higher income adults had higher odds of using all types of weight loss strategies compared to lower income adults. Adults with college education had higher odds of using eating and both eating and PA when compared to those with high school education. Older children (6-11 and 12-19 years) had higher odds of using PA when compared to younger children (2-5 years). Children of foreign-born parents (> 10 years in the US) had higher odds of using eating to lose weight compared to the children of US born parents. Children overall had higher odds of adopting a weight loss strategy if it was also adopted by the parent. In subgroup analysis, parent-child dyads had higher odds of adopting similar strategies among older children (12-19) and among girls, but this association did not hold true for younger children (2-11 years) and among boys for PA.

Conclusion: Older OWOB children (12-19) and female children had higher odds of adopting their parents’ weight loss strategies. Younger children did not follow the same pattern as their parents and among boys concordance was observed only for eating strategies. Results from the study may inform future family-based weight management interventions.
