Self-reported drug utilization, health, and lifestyle factors among 70-74 year old community dwelling individuals in Western Norway. The Hordaland Health Study (HUSK)

Background: To examine the level and patterns of self-reported medication use ( prescription and non-prescription drugs) among 70 - 74 year old individuals living in the community, and to explore self-reported indications for use, and factors possibly predictive of drug use. Methods: A health survey carried out in 1997 - 99 in the county of Hordaland ( Western Norway) in the setting of a population study. A self-administered questionnaire was mailed to 4338 persons born in 1925 - 27, and a health check-up was offered. Drug use the previous day was reported ( point prevalence). 3341 (77.0%) persons who responded, comprise the material for the analyses. Results: Between one third ( males) and one quarter ( females) did not take any drug the previous day. Mean number of drugs among users was 2.8 ( men and women). 32% used three or more drugs and 11.5% five or more. Hypertension and other cardiovascular problems were by far the most common reasons for drug use, followed by respiratory, musculoskeletal and mental health problems. Self-reported poor health, a high Body Mass Index (BMI), and being an ex-smoker ( but not currently a smoker) correlated with increasing number of drugs taken. Conclusion: Among 70-74-year old individuals living in the community no use of medication was more common than major polypharmacy (5+ drugs). Persons who had fallen ill and were put on regular medication, probably tended to quit smoking, while those who remained healthy, continued to smoke.
