Child body mass index, genotype and parenting in the prediction of restrictive feeding.

摘要: SummaryBackground Restrictive feeding is implicated in pediatric obesity, and caregivers increase controlling practices on the basis of higher child weight status. However, few studies have examined how genetic parenting characteristics together impact restrictive feeding. Objectives We whether body mass index (BMI) status predicts caregiver use if this association moderated by (i) strategies to manage their children's distress (ii) variations catechol-O-methyltransferase (COMT) gene (Val158Met, rs4680). Methods Participants included 126 Caucasian children (50% girls) who were participating a larger study USA. Caregivers reported responses when 2.5–3.5 years age. Child anthropometric measurements also obtained. Restrictive was assessed again 1–1.5 years later. Genomic DNA obtained from saliva samples, COMT-rs4680 genotyped using TaqMan® methodology. Results Child BMI percentile predicted subsequent for Met/Met had reporting negative distress. For Val carriers, below mean these responses. Conclusions Caregivers are at risk percentiles, increases more ineffective stress regulation homozygous Met allele. Prevention programmes might focus behaviours that foster emotion consider variation parenting.
