Occupation- and age-related differences in work absence due to frequent cardiovascular diseases using essential hypertension and acute myocardial infarction as examples

Cardiovascular diseases (CVD) are responsible for a major part of morbidity and mortality. Based on two selected diagnoses (ICD-10) "essential hypertension" (I10) and "acute myocardial infarction" (AMI, I21) the occupational- and age-dependent increases in sick leave are described. The secondary data analysis is based on gender-stratified, pooled data (26.2 million legally insured) on sick leave of the German social security workforce in 2008. The number of sick leave cases stratified by sex and age were calculated. Indirectly standardized morbidity ratios (SMR) for the occurrence of sick leave cases stratified by age and occupational groups (according to Blossfeld) with 99.99% confidence intervals are estimated. Age had an influence on the professional group-dependent sick leave. In the youngest age group, a similar risk existed for hypertension and AMI in all occupational groups. In the middle and older age groups, low-skilled service workers and manual occupations had increased risks for both men and women as compared to the occupational group of qualified sales and administrative occupations. Because the workforce is expected to continue to age in the future, primary and secondary prevention of CVD in all age groups is strongly recommended.
