| Male (N=308) | Female (N=299) | p | Total (N=607) | |
|---|---|---|---|---|
| Weight class | % (CI 95) | % (CI 95) | % (CI 95) | |
| Thinness grade 1–3 | 2.3 (0.6–3.9) | 3.3 (1.3–5.4) | 0.424 | 2.8 (1.5–4.1) |
| Normal weight | 79.2 (74.7–83.8) | 69.9 (64.7–75.1) | 0.008 | 74.6 (71.2–78.1) |
| Overweight | 12.7 (8.9–16.4) | 19.1 (14.6–23.5) | 0.031 | 15.8 (12.9–18.7) |
| Obesity | 5.8 (3.2–8.5) | 7.7 (4.7–10.7) | 0.36 | 6.8 (4.8–8.8) |
Proportions compared using Chi square test. P-value below 0.05 was used as significance level. Significant values are presented in bold. Thinness grade III corresponds to BMI below 16 kg/m2, thinness grade II to BMI below 17 kg/m2 and thinness grade I to BMI below 18.5 kg/m2 at age 18 years while overweight BMI corresponds to BMI above 25 kg/m2 and obesity BMI to BMI above 30 kg/m2 at age 18 years. CI 95: 95% confidence intervals.
