Investigations into childhood obesity found that parental overweight, high birth weight, low social class, and low physical activity were the main risk factors. Using a composite score can help identify children at risk of overweight/obesity.
Background Investigations into the main drivers of childhood obesity are vital to implement effective interventions to halt the global rise in levels. The use of a composite score may help to identify children most at risk of overweight/obesity. Objectives To investigate the cumulative impact of factors associated with overweight/obesity risk in children. Methods Data were analysed from the Irish National Children's Food Survey II which included 600 children, aged 5-12-years. The risk factors examined included social class, parental, early life, lifestyle, and dietary components. A composite score was calculated which ranged from 0 (no risk factors for overweight/obesity) to 4 (4 risk factors for overweight/obesity). Results In model 1 (%BF) the four factors associated with overweight/obesity risk were having a parent with overweight/obesity (odds ratio 3.1; 95% confidence interval 1.9-4.8), having a high birth weight of >= 4 kg (2.5; 1.6-3.9), being from a low social class (2.3; 1.4-3.8) and low physical activity (1.9; 1.2-2.8). Children who scored 3-4 points on the composite score had a 10-fold (10.0; 4.2-23.9) increased risk of overweight/obesity compared to those with 0 points, a sevenfold (7.2; 3.9-13.5) increased risk compared to those with 1 point and a threefold (2.6; 1.4-4.8) increased risk compared to those with 2 points, with similar results observed in model 2 (BMI). Conclusion The use of a composite score is a beneficial means of identifying children at risk of overweight/obesity and may prove useful in the development of effective interventions to tackle childhood obesity.
