The prevalence of obesity is increasing.
Cardiovascular screening among persons 40-42 years has been carried out since 1985 in all but one of the 19 Norwegian counties. In eight counties, screening was carried out both in 1994-96 and 1997-99.
The prevalence of obesity (body mass index > or = 30 kg/m2) in the eight counties increased from 9.6% in men and 8.8% in women in 1994-96 to 14.0% and 11.6% in 1997-99. The relative increase was on the whole the same in all subgroups of the study population. There were strong cross-sectional relationships between lifestyle factors, general health, length of education and obesity. Changes in the distribution of these factors between the two periods did not at all explain the increased prevalence of obesity.
The prevalence of obesity is increasing in practically all segments of the population.
肥胖症的患病率正在上升。
自1985年起，挪威19个郡中除一个郡外，都对40至42岁的人群进行了心血管筛查。在八个郡，分别于1994 - 1996年和1997 - 1999年进行了筛查。
这八个郡中，肥胖症（体重指数≥30千克/平方米）的患病率从1994 - 1996年男性的9.6%和女性的8.8%，上升至1997 - 1999年的14.0%和11.6%。总体而言，研究人群的所有亚组中相对增幅相同。生活方式因素、总体健康状况、受教育年限与肥胖症之间存在密切的横断面关系。这两个时期这些因素分布的变化根本无法解释肥胖症患病率的上升。
几乎所有人群中的肥胖症患病率都在上升。
