Secondary analysis showing estimates of the FFV policy effect excluding NFFV schools that took part in the parental paid subscription program on BMI_SDS, OW/OB, WC, and WtHR at 8.5 years.

(a) BMI_SDS; (b) OW/OB; (c) WC; (d) WtHR. Results are presented by sex and cohort (including pooled) and for each model. Expressed as the difference in outcome or OR versus the counterfactual (as estimated using the NFFV schools) with 95% CI. Analysis of BMI_SDS and OW/OB: Pooled models include terms for cohort (intercept and slope). Adjusted models include region, population density, and highest parental education (all intercept and slope). +Pre-intervention adjusted models additionally include adjustment for BMI_SDS prior to the intervention. Note: Pre-intervention slopes were constrained to be the same in each group for all models except for BMI_SDS in 2015 cohort girls. Analysis of WC and WtHR: Outcomes are from grade 3 only. Pooled models include a term for cohort. Adjusted models include region, population density, and highest parental education. BMI_SDS, body mass index standard deviation score; FFV, free fruit and vegetable; NFFV, no free fruit and vegetable; OR, odds ratio; OW/OB, overweight and obesity; WC, waist circumference; WtHR, waist to height ratio.
