THE TROMSO STUDY - FREQUENCY AND PREDICTING FACTORS OF ANALGESIC DRUG-USE IN A FREE-LIVING POPULATION (12-56 YEARS)

In a cross-sectional survey carried out in Tromso in 1986-7, 19,137 men and women aged 12-56 years from the general population were asked about their use of drugs during the preceding 14 days. Use of analgesics was very common. On average 28% of the women and 13% of the men had used analgesics. Drug use due to menstruation discomfort contributed only partly to the gender difference. Drug use was independent of age from 20 years of age. Factors having an impact on analgesic drug use were analyzed by logistic regression. The most significant predictors of analgesic use were suffering from headache ((OR = 14.2(women) OR = 24.4(men)) and infections ((OR = 2.0(women) OR = 2.4(men)). Drug users also tended to suffer from symptoms of depression (women) and sleeplessness (men). Lifestyle and sociodemographic factors were also significant predictors, but were of marginal importance (OR < 1.5) compared with occurrance of pain and infections.
