Comparison of Tucson and Cracow Longitudinal Studies: Results (Part 1)

Characteristics of the Analyzed Groups
The Tucson and Cracow analyzed groups differed markedly with respect to age and smoking habits (Table 1). The Tucson sample was stratified according to age, while the age structure of the Cracow sample was representative for the Cracow population. As a result, the proportion of subjects aged 51 to 70 years was much greater in Tucson (31.7 percent of men analyzed here and 50.2 percent women) than in the Cracow group (21.0 percent and 21.8 percent, respectively). The proportion of men smoking at the time of the initial survey was much greater in Cracow than in the Tucson study group, but the proportion of former smokers was twice as large in Tucson; the proportion of ever-smoking men was greater in Cracow. Among women, smoking was more prevalent among Tucson subjects, with the greatest difference between cities in the proportions of exsmokers. For both sexes, the intensity of smoking was much greater in Tucson than in Cracow (38 percent of men who continued smoking during the follow-up smoked more than 25 cigarettes daily in Tucson and 20 percent in Cracow; 30 percent vs 6 percent in women). The initial mean percent predicted FEV! level was lower in the Tucson group, and this was associated with a higher proportion of subjects with FEVi below 75 percent of the predicted level in Tucson. buy diabetes drugs
