Cohort of Swedish Men
The general aim of the study is to assess a wide range of modifiable lifestyle factors (diet, dietary supplements, physical activity, smoking, alcohol, body weight and other anthropometric measures, etc.) and genetic factors in a large population-based longitudinal cohort of Swedish middle-aged and elderly men.
- Extensive questionnaire-based data on diet and other lifestyle factors enables studies of relevance for primary and secondary prevention of cancer (common and rare types), cardiovascular diseases, type 2 diabetes, osteoporosis, neurodegenerative diseases, age-related cataract, rheumatoid arthritis, lower urinary tract symptoms, chronic obstructive pulmonary disease, obesity etc.
- Extensive register-based information on health status facilitates studies of multimorbidity, polypharmacy, ageing, and overall and cause-specific mortality.
- Biorepository with a broad spectrum of samples (saliva, blood, urine, adipose tissue, faeces), complemented with clinical data, enables studies of genetic factors and other factors of relevance for detection of biomarkers for early diagnosis and progression.
