  1. BMI, body mass index; CI, confidence interval; PA, physical activity
  2. Model 1: adjusted for weight, PA or sedentary behaviours at baseline
  3. Model 2: Model 1 + baseline age, sex, education, follow-up length and parenting transitions
  4. β (95% CI) in bold means statistically significant difference compared to the reference group (became partnered vs. stayed not partnered, became separated/divorced/widowed vs. stayed partnered both times)
