What Factors Influence Uptake into Family-Based Obesity Treatment after Weight Screening?

ObjectivesTo determine what factors drive participation in a family-based weight management program for 4- to 8-year-old children following screening for overweight or obesity.Study designChildren (n = 1093) attended a comprehensive screening appointment where parents completed questionnaires on demographics, motivation for healthy lifestyles, feeding practices, and beliefs about child size, prior to feedback about the child's weight. Parents of overweight or obese children (body mass index ≥85th percentile) attended a follow-up interview to assess reactions to feedback and willingness to participate in a 2-year intervention.ResultsA total of 271 (24.8%) children were overweight or obese with 197 (72.7%) agreeing to the intervention. Socioeconomic status differed in intervention participants (n = 197) compared with non-participants (n = 74), whereas no differences were observed in parental feeding practices, ineffective parenting practices, or self-determined forms of motivation. However, fewer non-participating parents believed their child to be overweight (23% vs 49%, P < .001) or were concerned about it (16% vs 43%, P < .001), despite children having an average body mass index approximating the 95th percentile. Non-participating parents did not expect their child to be overweight (P = .002) and rated receiving this information as less useful (P = .008) than participating parents.ConclusionPreconceptions about child weight and reactions to feedback determined intervention uptake more than parenting or motivation for health. Many parents agreed to participate in the intervention despite not viewing their child as overweight.
