Association of depressive symptoms and physical functioning within employment grade before and after adjustment for baseline risk factors* and baseline health status†

	Odds ratios for high depression score by poor physical functioning (95% CI)					Residual correlations between depression and physical functioning‡
Employment grade	age	age, grade	age, risk factors	age, baseline health	age, risk factors baseline health	age	age, risk factors baseline health
*Baseline risk factors: health behaviours (smoking, alcohol consumption, physical activity), work (decision latitude, job demands, work social supports, effort-reward imbalance), marital status, social support (confiding/emotional, practical, negative aspects, network size), housing tenure, material problems, life events in preceding 12 months. †Baseline health (physical illness, health problems in past year, longstanding illness, depression score, total GHQ score, body mass index, blood pressure). ‡Residual correlations from multivariate analysis of log transformed depression and physical functioning scores.
