a
Belstress, FPS, HeSSup and Whitehall II. Median follow-up 4 years.
b
Participants who were of normal weight or overweight at baseline.
c
Odds ratios are adjusted for age, sex, socio-economic status (SES).
d
The corresponding age- and sex-adjusted odds ratios were 1.16 (95% CI 0.89–1.53) in the low-SES group (n = 7923), 1.18 (95% CI 0.97–1.43) in the intermediate-SES group (n = 23 151) and 1.25 (95% CI 0.86–1.83) in the high-SES group (n = 11 148).
