Odds ratios (ORs) and 95% confidence intervals obtained using the survey command for logistic regression. Cut-points for worries, tension, lack of joy and demands were ≥9, ≥11, ≥11, ≥12 for men; and ≥10, ≥12, ≥12, ≥13 for women, respectively. Analyses were unadjusted and multivariable adjusted for age, sex, BMI [body mass index], energy intake, relationship status, physical activity, level of education, SEIFA [Socio-economical index for areas], smoking status, diabetes and prior of cardiovascular disease).
Indicates a statistically significant difference (p < 0.05) from Q1;
indicates a statistically significant difference (p < 0.013) from Q1 based on Bonferroni-corrections.
