OBJECTIVE: The purpose of this study is to investigate the possible link between standing height and physical disability among U.S. adults aged 60 years and older.
METHODS: The cross-sectional data were obtained from the US National Health and Nutrition Examination Survey (NHANES) 2015-2018. Physical disability was assessed by six questions: \"Have serious difficulty hearing (SDH)?\", \"Have serious difficulty seeing (SDS)?\", \"Have serious difficulty concentrating (SDC)?\", \"Have serious difficulty walking (SDW)?\", \"Have difficulty dressing or bathing (DDB)?\" and \"Have difficulty doing errands alone (DDEA)?\". Responses to these questions were \"yes\" or \"no\". Answer yes to one of the above six questions was identified as physical disability. Standing height (cm) was measured with an altimeter. Multivariate logistic regression was performed to examine the possible link between standing height and physical disability after adjustment for all covariates.
RESULTS: A total of 2624 participants aged ≥ 60 years were included in our study, including 1279 (48.7%) females and 1345 (51.3%) males. The mean age of participants was 69.41 ± 6.82 years. After adjusting for all potential confounders, the inverse relationship between standing height and all physical disability (APD) was statistically significant (OR = 0.976, 95%CI:0.957-0.995). In addition, among six types of physical disability (SDH, SDS, SDC, SDW, DDB, DDEA), standing height was also a protective factor for SDW (OR = 0.961, 95%CI:0.939-0.983) and DDEA (OR = 0.944, 95%CI:0.915-0.975) in the full-adjusted model.
CONCLUSIONS: The cross-sectional population based study demonstrates that standing height is a protective factor for physical disability among U.S. adults aged 60 years and older.
目的:这项研究的目的是调查美国60岁及以上成年人站立身高与身体残疾之间的可能联系。
方法:横断面数据来自2015-2018年美国国家健康与营养调查(NHANES)。身体残疾通过六个问题进行评估:“听力有严重困难(SDH)?”“有严重的视力困难(SDS)?”,“有严重的注意力集中困难(SDC)?”,“有严重的行走困难(SDW)?”“穿衣或洗澡有困难(DDB)?”和“单独做差事有困难(DDEA)?”对这些问题的回答是“是”或“否”。对上述六个问题之一的回答是被确定为身体残疾。站立高度(cm)用高度计测量。在调整所有协变量后,进行多变量逻辑回归以检查站立身高与身体残疾之间的可能联系。
结果:共有2624名年龄≥60岁的参与者被纳入本研究,包括1279名(48.7%)女性和1345名(51.3%)男性。参与者的平均年龄为69.41±6.82岁。在调整了所有潜在的混杂因素后,站立身高与所有身体残疾(APD)之间的负相关具有统计学意义(OR=0.976,95CI:0.957-0.995)。此外,在六种身体残疾类型中(SDH,SDS,SDC,SDW,DDB,DDEA),在全校正模型中,站立高度也是SDW(OR=0.961,95CI:0.939~0.983)和DDEA(OR=0.944,95CI:0.915~0.975)的保护因素.
结论:基于横断面人群的研究表明,站立身高是美国60岁及以上成年人身体残疾的保护因素。
