) and overweight (BMI ≥ 25 kg/m
) according to residence distance and population density. Body mass index (BMI; kg/m2) and percentage of overweight (BMI ≥ 25 kg/m2) in relation to individual’s road distance (km) to the resident commune’s densest grid, and on population density of the resident grid (inhabitants/km2). Continuous line indicates the regression-based estimate for BMI and the prevalence of overweight, smoothed by a cubic spline with 4 degrees of freedom (95% confidence bands shown by dashed lines). Residential area types are marked by Arabic numerals: 1 scattered settlements; 2 rural areas proper; 3 transition zones; 4 built-up areas & suburbs; 5 high-rise centres. Upper row: crude BMI and prevalence of overweight. Lower row: regression-based gradients compared with the baseline, adjusted for sex, marital status, occupational class, education, leisure-time and occupational physical activity, alcohol consumption and smoking.
