Results from logistic regression between green areas (1 km and 5 km buffers) and outcome variables (overweight and obesity) based on the Norwegian Youth Study, 2001–2004 (n = 10,527).

In the “unadjusted” model, we adjusted for age, gender, and ethnicity. In the adjusted model, we also adjusted for physical activity, transportation mode, use of nature, social support from friends and family, family situation, diet, smoking habits, county, moving history, and climatic variables (precipitation, altitude, and temperature).
