目的评估1992年至2014年美国老年人和主要人群亚组疼痛患病率的趋势，并检验这种趋势是否可以用人口构成的变化来解释。方法健康与退休研究资料包括任何疼痛、疼痛强度和因疼痛导致的日常活动限制的信息。患病率的平均年变化百分比是计算任何和2个级别的疼痛（轻度/中度和非限制性以及严重和/或限制性），跨越人口统计学和社会经济特征，以及患有和不患有特定慢性疾病的人。广义线性潜模型和混合模型检验调整协变量的趋势。结果总体人群和亚组中疼痛患病率呈线性和广泛增加。根据年龄和性别的不同，年平均增长率在2%-3%之间。增加在亚组中是一致的，随着时间的推移而持续，而不是由于人口组成的变化。如果教育程度没有随着时间的推移而增加，疼痛患病率的增长将会更高。美国老年人疼痛患病率的增加令人担忧，并可能达到流行病的程度。人口健康研究必须监测和了解这些令人担忧的趋势。
Objectives Assess trends in pain prevalence from 1992 to 2014 among older U.S. adults and by major population subgroups, and test whether the trends can be explained by changes in population composition.Methods Health and Retirement Study data include information on any pain, pain intensity, and limitations in usual activities due to pain. Average annual percent change in prevalence is calculated for any and for 2 levels of pain-mild/moderate and nonlimiting and severe and/or limiting-across demographic and socioeconomic characteristics, and for those with and without specific chronic conditions. Generalized linear latent and mixed models examine trends adjusting for covariates.Results Linear and extensive increases in pain prevalence occurred across the total population and subgroups. The average annual percent increase was in the 2%-3% range depending upon age and sex. Increases were consistent across subgroups, persistent over time, and not due to changes in population composition. Without increases in educational attainment over time, pain prevalence increases would be even higher.Discussion The increases in pain prevalence among older Americans are alarming and potentially of epidemic proportions. Population-health research must monitor and understand these worrisome trends.
