目的：描述70-89岁人群腰围和腹部肥胖的模式和趋势，对比标准和新的年龄相关切点，并探讨其随时间、年龄和教育水平的变化。方法：研究对象为1993-2010年参加英国健康调查的7129名男性和9244名年龄在70-89岁之间的女性。结果测量为腰围百分位数和以腰围为基础的腹部肥胖标准指标和新指标。采用二项回归和分位数回归研究与关键解释变量的关系。结果：自1993年以来，英格兰社区老年人的腰围分布呈上升趋势（男性中位腰围增加4.5 cm，女性中位腰围增加5.1 cm）。腹部肥胖的患病率有所上升，而低风险组的患病率有所下降。与80-89岁的人相比，70-79岁的人腹部肥胖的比例更高，而且离开教育的年龄也更早。腹部肥胖的流行程度在新的和标准的分界点上有很大的不同，这使得在包括整个成年年龄段的人群中使用新的分界点是不切实际的。结论：肥胖在老年人中呈上升趋势，但需要更多的工作来设计基于腰围的适合年龄的高风险指标。
Objectives: To describe the patterns and trends in waist circumference and abdominal obesity for those aged 70-89 contrasting the standard and new age-related cut-points, and to investigate how they vary with time, age and educational level.Methods: The subjects were 7129 men and 9244 women aged 70-89 years who participated in the Health Survey for England during 1993-2010. The outcome measures were the percentiles of waist circumference and standard and new indicators of abdominal obesity based on waist circumference. Binomial and quantile regression were used to investigate the relationship with key explanatory variables.Results: The distribution of waist circumference among community-dwelling older adults in England has shifted upwards since 1993 (an increase in median of 4.5 cm in men and 5.1 cm in women). The prevalence of abdominal obesity has increased, while those in the low-risk group have decreased. Abdominal obesity was higher in those aged 70-79 compared to 80-89, and in those who left education earlier. The prevalence of abdominal obesity varies considerably with new and standard cut-points, which makes it impractical to use the new ones on a population that includes subjects across the adult age range.Conclusions: Obesity is increasing among the elderly, but more work is needed on devising age-appropriate indicators of high risk based on waist circumference.
