¹n: number of subjects in the sample; N: estimated number of subjects in the Swiss population; BMI: body mass index kg/m²; CI: confidence intervals. All BMI figures are population corrected (weighted) and are based on arithmetic means within age and gender groups. SHS BMI was calculated using self-reported height and weight, asterisks denote significant group differences between average SHS BMIs and their corresponding NBPW BMIs (see Table 4).* p < 0.05; ** p < 0.01; *** p < 0.001.
