Sickness absence diagnoses among abstainers, low‐risk drinkers and at‐risk drinkers: consideration of the U‐shaped association between alcohol use and sickness absence in four cohort studies

Table S1 Observed diagnosis‐specific sickness absence days by alcohol use in each cohort. The highest mean on each row is shown in bold type. Table S2 Adjusted* rate ratios (95% confidence intervals) for the association between alcohol use and diagnosis of sickness absence. Pooled data (n = 47 520). Table S3 Adjusted* rate ratios (95% confidence intervals) for the association between alcohol use and diagnosis of sickness absence. Pooled data (n = 47 520). Figure S1 Rate ratios (95% confidence intervals) for the association between alcohol use and sickness absence due to mental disorders in each study cohort (n = 47 520). Abstainers, former, persistent and new at‐risk drinkers are compared to low‐risk drinkers. Adjusted for age, socio‐economic status, smoking and body mass index. I–V = fixed‐effects model; D + L = random‐effects model. Figure S2 Rate ratios (95% confidence intervals) for the association between alcohol use and sickness absence due to musculoskeletal disorders in each study cohort (n = 47 520). Abstainers, former, persistent and new at‐risk drinkers are compared to low‐risk drinkers. Adjusted for age, socio‐economic status, smoking and body mass index. I–V = fixed‐effects model; D + L = random‐effects model. Figure S3 Rate ratios (95% confidence intervals) for the association between alcohol use and sickness absence due to diseases of the circulatory system in each study cohort (n = 47 520). Abstainers, former, persistent and new at‐risk drinkers are compared to low‐risk drinkers. Adjusted for age, socio‐economic status, smoking and body mass index. I–V = fixed‐effects model; D + L = random‐effects model. Figure S4 Rate ratios (95% confidence intervals) for the association between alcohol use and sickness absence due to diseases of the digestive system in each study cohort (n = 47 520). Abstainers, former, persistent and new at‐risk drinkers are compared to low‐risk drinkers. Adjusted for age, socio‐economic status, smoking, and body mass index. I–V = fixed‐effects model; D + L = random‐effects model. Figure S5 Rate ratios (95% confidence intervals) for the association between alcohol use and sickness absence due to diseases of the respiratory system in each study cohort (n = 47 520). Abstainers, former, persistent and new at‐risk drinkers are compared to low‐risk drinkers. Adjusted for age, socio‐economic status, smoking and body mass index. I–V = fixed‐effects model; D + L = random‐effects model. Figure S6 Rate ratios (95% confidence intervals) the association between alcohol use and sickness absence due to injury/poisoning in each study cohort (n = 47 520). Abstainers, former, persistent and new at‐risk drinkers are compared to low‐risk drinkers. Adjusted for age, socio‐economic status, smoking and body mass index. I–V = fixed‐effects model; D + L = random‐effects model.
