Furthermore, the possible effect of dietary changes on the observed trend in obesity prevalence was evaluated. Material and methods: Participants came from stages III-V in the Reykjavik Health Study and the Reykjavik part of the MONICA studies from the period 1975-1994. The age groups 45-54 years and 55-64 years were examined. Only the information from the first visit of each person was included. The body mass index (BMI) for the participants was calculated and the percentage of those subjects considered overweight and obese according to WHO standards evaluated, using 25BMI<30 kg/m(2) as the cut-off point for overweight and BMI30 kg/m(2) as the cut-off point for obesity. Also, the observed trend in obesity prevalence is compared to changes in diet that have occurred in the same period. Results: The results show that the mean weight and height of both men and women have been increasing during the study period. However, weight has increased more than can be accounted for by increased height, resulting in increased BMI. At the same time, the prevalence of overweight and obesity have increased, the relative increase in obesity far exceeding the relative increase in overweight. The prevalence of obesity more than doubled in both age groups of women during the study period, according to trend analyses. At the end of the period, almost 15% (95% confidence interval (CI), 9-22%) in the younger group of women and 25% (95% CI, 17-34%) in the older group were classified as obese. In the younger group of men, the prevalence of obesity almost doubled, while the observed increase in the older group was not statistically significant, according to trend analyses. The prevalence of obesity in the final period was about 19% (95% CI, 13-27%) and 17% (95% CI, 11-25%) in the younger and older ...
