In contrast, AAT, AP, and ASD were positively associated with the prevalence of abdominal obesity in all regions, with regression coefficients ranging from 0.088 to 1.410 for AAT and showing a spatial pattern of decreasing from north-east to south-west, and 0.122 to 0.172 for ASD, and a spatial pattern of decreasing from north to south. This evidence concerns the gene SERPINA1 and Abdominal obesity.
