^a Adjusted for age at TP2 and sex. ^b Adjusted for age at TP2, sex, baseline manual social class, baseline lower education level, current cigarette smoker at TP2, body mass index > 30 kg/m² at TP2. Multiple imputation was used for 1733 missing BMI at TP2 calculated using baseline BMI and other covariates for participants who completed questionnaires but did not attend a health examination
