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: 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.
