All predictors were adjusted with each other in multilevel modeling. Underweight, normal, overweight, and obesity are defined by BMI < 18.5 kg/m2, 18.5–24.9 kg/m2, 25–29.9 kg/m2, and ≥30 kg/m2, respectively. Period 1: 2002–2004; period 2: 2008–2010. PSE index: physical and social environmental index (towards worse). Quarter 1: PSE index, 0.50–<0.62.
