Table 1 Association between strong (score 0 or 1) versus weak (score 2–6) sense of coherence (SOC, hazard ratios (HR) and 95% confidence intervals (CI)) and all-cause mortality, and the attenuation in this association, with progressive adjustments for measures of socioeconomic status and lifestyle choice

	HR (95% CI)	Log HR	% Attenuation in log HR*
Baseline†	0.77 (0.69 to 0.85)	−0.262	–
Adjusted for:
Measures of socioeconomic status‡
Social class	0.79 (0.71 to 0.88)	−0.233	11.7
Education	0.79 (0.71 to 0.87)	−0.238	9.1
Both	0.80 (0.72 to 0.89)	−0.224	15.3
Measures of lifestyle choice§
Cigarette smoking	0.79 (0.71 to 0.87)	−0.240	7.7
Physical activity	0.79 (0.71 to 0.87)	−0.242	7.7
Dietary intake of fruit and vegetables	0.78 (0.69 to 0.87)	−0.253	5.7
Dietary intake of fibre	0.78 (0.70 to 0.87)	−0.250	4.1
All	0.80 (0.72 to 0.90)	−0.219	14.4
Socioeconomic status and lifestyle choice	0.82 (0.73 to 0.92)	−0.197	23.2

*Based on a comparison of the log hazard ratios for SOC with and without adjustment for each (set of) measure(s) (after exclusion of participants with missing data on any of the measures considered, and with additional adjustment for age and sex).
†Adjusted for age, sex and age–sex interaction.
‡Social class – I, II, III non-manual, III manual, IV, V. Education – no qualifications, to age 16, to age 18, degree level.
§Cigarette smoking – current, former, never. Physical activity – physically inactive, moderately inactive, moderately active, active. Dietary intake of fruit and vegetables and of fibre – both included as a categorical variable in quintiles.
