Factors associated with dropout in a lifestyle modification program for weight management in children and adolescents

Abstract

BackgroundSignificant dropout rates remain a serious concern in pediatric weight control program, but few studies have identified predictors of dropout. AimsThe objective of the study is to identify factors associated with dropout from a pediatric lifestyle modification weight control program at different phases. MethodsData on overweight and obese participants (n = 242) aged 11–18 years in the Intervention for Childhood and Adolescent Obesity via Activity and Nutrition (ICAAN) study were collected at baseline, 6-months, and 24-months through self-report and a laboratory test. Logistic regression analysis was performed for those who dropped out during the first 6-months, and multivariate generalized estimating equation analysis identified longitudinal factors associated with those who dropped out after 24 months. ResultsLower family functioning (OR = 2.30, 95% CI [1.18−4.46]), exercise group (OR = 0.36, 95% CI [0.15−0.86]), lower initial attendance rate (OR = 6.09, 95% CI [2.94−12.6]), and non-self -referral pathways (OR = 2.35, 95% CI [1.05−5.27]) were significantly associated with 6-month dropouts. For late dropout, lower family functioning (OR = 1.71, 95% CI [1.06−2.77]) and lower initial attendance rates (OR = 2.06, 95% CI [1.12−3.81]) remained significant. ConclusionFamily function and initial attendance rate were associated with lower dropout rates. Developing a supportive family environment and focusing on the early-stage factors at the intervention’s outset may reduce overall dropout rates in obesity prevention intervention.
