Follow-up refers to ages 36 to 60–64 years in 1946-NSHD and 33–50 years in 1958-NCDS; obesity trajectories are as defined in Table 3 footnotes.
Model 1: adjusted for gender, social class in early-life and adulthood; early adult BMI; mental health; smoking; physical activity (1958-NCDS only); highest educational qualification and illnesses: arthritis/rheumatism; diabetes; heart trouble; high blood pressure; and asthma; see Supplementary Table S1, available as Supplementary data at IJE online, for further details.
Model 2 adjusted for Model 1 factors and obesity/inactivity at the same age (as appropriate).
1946-NSHD only.
Model A: adjusted for gender.
Model B: additionally adjusted for social class in early-life and adulthood; early adult BMI; mental health; smoking; physical activity (1958-NCDS only); highest educational qualification and illnesses: arthritis/rheumatism; diabetes; heart trouble; high blood pressure; and asthma; see Supplementary Table S1, available as Supplementary data at IJE online for further details.
