Abstract

This study investigates disparities between older adults based on urbanicity in the United States. We analyzed data from 8259 participants aged 65+ from the 2018 Health and Retirement Study. The mean age was 74 (SD 8). Low-urbanicity participants (29%) were more likely white (88% vs. 77%, p < .001), and had lower education (20% vs. 16%, p-value = .017), higher rates of hypertension (69% vs. 66.3%, p = .035), lung disease (15% vs. 11%, p=<.001), and cognitive impairment (24% vs. 19%, p < .001). After adjustment for demographics, they were less physically active (60% vs. 55%, p = .021) and more dependent on IADLs (19% vs. 16%, p = .018). Urbanicity significantly affects physical abilities (i.e., jogging, climbing stairs, and handling objects) more in younger participants (65-75) than older ones (75+) (p for interaction = .003, .007, and .012, respectively). Significant urbanicity-based disparities in older adults' physical and functional abilities must be addressed to tailor interventions that improve their quality of life.

基于健康和退休研究的城市化与老年人功能和身体能力差异：一项横断面研究。

这项研究调查了基于美国城市化的老年人之间的差异。我们分析了2018年健康与退休研究中8259名65岁以上参与者的数据。平均年龄为74岁（SD = 8）。低城市化参与者（29%）更可能是白人（88%对77%，p < 0.001），受教育程度较低（20%对16%，p值= 0.017），高血压（69%对66.3%,p= 0.035），肺病（15%对11%，p=p < 0.001）。在人口统计学调整后，他们的身体活动较少（60%对55%，p = 0.021），更依赖于iadl（19%对16%，p = 0.018）。都市化显著影响年轻参与者（65-75岁）比年长参与者（75岁以上）的身体能力（即慢跑、爬楼梯和处理物体）（相互作用的p分别= 0.003、0.007和0.012）。必须解决基于城市的老年人身体和功能能力的显著差异，以便有针对性地采取干预措施，改善他们的生活质量。

期刊介绍： The Journal of Applied Gerontology (JAG) is the official journal of the Southern Gerontological Society. It features articles that focus on research applications intended to improve the quality of life of older persons or to enhance our understanding of age-related issues that will eventually lead to such outcomes. We construe application broadly and encourage contributions across a range of applications toward those foci, including interventions, methodology, policy, and theory. Manuscripts from all disciplines represented in gerontology are welcome. Because the circulation and intended audience of JAG is global, contributions from international authors are encouraged.
