1 Pearson’s Chi-squared test, 2 Linear Model ANOVA, 3 Lung function not captured for those < 6 years of age, 4 Adult individuals (≥ 18 years) were classified into BMI categories based on World Health Organization guidelines as underweight (< 18.5 kg/m2), adequate weight (18.5–24.9 kg/m2), or overweight (≥ 25.0 kg/m2). Children were classified as underweight (< 10th percentile), adequate weight (10–85th percentile), or overweight (> 85th percentile).
