Aim: To explore associations between baseline factors and weight-related outcomes among participants enrolled in a paediatric obesity trial.
Methods: We included children aged 6-12 years participating in a 2-year multidisciplinary family programme who attended a postintervention follow-up 36 months from baseline (n = 62). Outcome measures were change in body mass index standard deviation score (BMI SDS), reduction in BMI SDS ≥0.25 and change in waist circumference (WC). Independent variables included in linear and logistic regression models were age, sex, household income, parents' education, sleep duration, screen time and physical activity.
Results: Altogether, 26 children (42%) attained a reduction of BMI SDS ≥0.25. Higher family income and longer sleep duration were associated with greater change in BMI SDS (-0.05 per 100.000 NOK, p = 0.02, and -0.24 per hour, p = 0.02, respectively). Higher age was associated with greater change in WC (-2.1 cm per year, p = 0.01) but lower odds of attaining a reduction in BMI SDS ≥0.25 (OR per year 0.70, p = 0.04). There was a borderline statistically significant trend towards greater increase in WC with longer daily screen time (p = 0.05).
Conclusion: Age, family income and sleep duration at baseline were associated with weight-related outcomes 1-year postintervention.
