Abstract
Background: Parental weight status is a key predictor of childhood obesity. However, limited evidence exists on how longitudinal changes in parental BMI influence children's weight trajectories, particularly in families at elevated risk for type 2 diabetes. Objectives: To investigate children's body mass index-for-age z-score (BMIz) changes over a 2-year period, associated with independent and cumulative changes in parents' BMI. Methods: In the Feel4Diabetes study, data from 12 280 children (age: 8.2 ± 1.0 years) and their parents were analysed to assess changes in child BMI-for-age z-scores over 2 years in relation to parental BMI changes. Analyses were adjusted for study design and baseline socio-demographic factors and were conducted in both the total sample (all-families) and high-risk for type 2 diabetes families (HR-families). Results: In the all-families dataset, a 1 kg/m2 independent decrease in maternal and paternal BMI was associated with a −0.037 (−0.041, −0.033) and −0.027 (−0.031, −0.023) change in child's BMIz [mean (95% CI)]. The joint parental effect was stronger [−0.32 (−0.36, −0.28)], particularly in HR-families [−0.34 (−0.42, −0.26)]. Conclusions: Parental BMI reductions, especially when both parents are involved, contribute to favourable BMI changes in children. The changes were more pronounced in HR-families, underscoring the need for interventions targeting the whole family in populations at elevated risk for type 2 diabetes.
