目的：通过评估1964年至1994年间丹麦男性和女性肥胖患病率和中位体重指数的长期变化，通过评估出生队列和年龄在多大程度上检验肥胖流行在成人中的普遍现象。设计：多项横断面人口调查。背景：丹麦大哥本哈根地区。研究对象：17065名男性(30336名观察)和13417名女性(24065名观察)，主要观察指标：根据测量的身高和体重在10岁年龄组中估计的BMI中位数和肥胖率的趋势。结果：肥胖率总体上呈上升趋势，尽管不规律：在20世纪70年代和90年代的两个阶段中，男性肥胖率上升，而女性肥胖率仅在90年代上升。在出生队列和年龄组之间观察到了很大的异质性。除了55岁的，几乎没有迹象表明女性肥胖率有上升的趋势。在男性中，除最年轻的年龄组外，所有年龄段的肥胖率都在增加，而且只有35-74岁的男性肥胖率在统计上有显著意义。除50岁及以上男性BMI呈上升趋势外，其余各年龄组的BMI中位数均无显著线性变化。结论：虽然丹麦肥胖患病率总体趋势与世界范围内的趋势相似，但呈显著上升趋势，且呈异质性，总体上既不一致，也不显著正相关；这种变化是不规则的，男女不同，不同年龄和出生年龄段的变化也不同。某些出生群体的中老年男性的肥胖问题构成了一个具体的公共卫生挑战。未来对肥胖症流行发展中异质性背后的决定因素的研究可能会为其原因提供线索。
Objective: To examine to what extent the obesity epidemic is a general phenomenon in adults by assessing the secular change, by birth cohort and age, in the prevalence of obesity and median body mass index (BMI) in Danish men and women measured between 1964 and 1994.Design: Multiple cross-sectional population surveys.Setting: The greater Copenhagen area of Denmark.Subjects: The study included 17 065 men (30 336 observations) and 13 417 women (24065 observations), aged 20-84 years.Main outcome measures: Trends in median BMI and prevalence of obesity estimated from measured height and weight in 10-year age groups.Results: In general the prevalence of obesity was increasing, although in an irregular way: among men in two phases, during the 1970s and 1990s and among women only during the 1990s. Great heterogeneity was observed between birth cohorts and age groups. There was only little indication of an increasing trend in obesity prevalence for women, except for the 55-64-year-olds. In men, the prevalence of obesity was increasing in all age groups except in the youngest ones, and it was statistically significant only for men aged 35-74 years. There was no significant linear change in median BMI in any group, except for an increasing trend among men aged 50 years and above.Conclusion: Although the overall Danish trend for obesity prevalence, similar to trends world-wide, showed a marked increase, the trend was very heterogeneous and generally neither uniform nor significantly positive; the changes were irregular, different among men and women, and different in the different age and birth cohorts. The obesity problem in middle-aged and older men of certain birth cohorts poses a specific public health challenge. Future studies of determinants behind the heterogeneity in the development of the obesity epidemic may provide clues to its causes.
