我们研究了儿童社会经济地位和成年身高与老年功能限制之间的关系。数据来自日本老年学评估研究2010年的基线调查，该研究是一个基于人口的队列，年龄为千分之一日元65岁，来自日本27个市（N = 15，499）。65-69岁、70-74岁、75-79岁和千分之一80岁的人分别在0-4岁、5-9岁、10-14岁和千分之一15岁时经历了第二次世界大战的结束。2010年通过问卷自报获得儿童时期的主观社会经济状况和当前身高。使用经验证的问卷量表评估更高级别的功能能力。Poisson回归和稳健方差估计被用来确定儿童主观社会经济地位、身高和功能限制之间的关系，儿童主观社会经济地位越低，高水平功能能力限制的患病率越高，无论年龄组如何。身高仅在70-74岁年龄组中与功能限制相关：（男性为千分之一日元170厘米，女性为千分之一日元160厘米）与身高较短的人相比，（男性< 155 cm，女性< 145 cm）完全调整模型中的个体（患病率比：0.84，95%可信区间：0.74-0.96）。无论年龄组如何，儿童期主观社会经济地位低与功能受限有强相关性。此外，那些在进入青春期之前经历过第二次世界大战并获得较低身高的人更有可能在老年时报告功能限制。
We examined the associations between childhood socioeconomic status and adulthood height with functional limitations in old age.Data were obtained from the baseline survey of the Japan Gerontological Evaluation Study 2010, a population-based cohort of people aged a parts per thousand yen65 years enrolled from 27 municipalities across Japan (N = 15,499). People aged 65-69, 70-74, 75-79, and a parts per thousand yen80 years experienced the end of World War II when they were aged 0-4, 5-9, 10-14, and a parts per thousand yen15 years, respectively. Subjective socioeconomic status during childhood and current height were obtained by self-report through questionnaire in 2010. Higher-level functional capacity was assessed using a validated questionnaire scale. Poisson regression with robust variance estimator was employed to determine the association between childhood subjective socioeconomic status, height, and functional limitations.Lower childhood subjective socioeconomic status was consistently associated with higher prevalence rate ratio of limitations in higher-level functional capacity, regardless of age cohort. Height was associated with functional limitation only among the group aged 70-74 years: taller (a parts per thousand yen170cm for men and a parts per thousand yen160cm for women) people were 16% less likely to report functional limitation in comparison with shorter (< 155 cm for men and < 145 cm for women) individuals in the fully adjusted model (prevalence rate ratio: 0.84, 95% confidence interval: 0.74-0.96).Low childhood subjective socioeconomic status had a robust association with functional limitation regardless of age cohort. In addition, those who lived through World War II before they reached puberty and attained shorter height were more likely to report functional limitations in old age.
