Association between obesity and body mass index (BMI) and the rs7559479 polymorphism, adjusted by age and sex in both samples (values for BMI are the mean ±SE; “% Non-obese” indicates the % of non-obese subjects carrying AA or AG-GG genotypes, “% Obese” indicates the % of obese subjects carrying AA or AG-GG genotypes; bold indicates significance)
| Genotype | N | BMI | % Non-obese | % Obese | Obesity, OR (95% CI) |
| AA | 1062 | 26.41 (0.13) | 877 (59.6%) | 185 (50.7%) | 1.00 |
| AG-GG | 774 | 26.96 (0.16) | 594 (40.4%) | 180 (49.3%) | 1.44 (1.14 to 1.82) |
| P value | 0.008 | 0.0024 |
