Self-rated Health (SRH) is regarded as a simple and valid measure of a person's health status, given its association to adverse health outcomes, including low physical performance in older populations. However, studies investigating these associations in low- and middle-income settings are scarce, especially for middle-aged populations. Understanding the validity of SRH in relation to objective health measures in low-income populations could assist in decision making about health policy and strategies, especially in under-resourced settings.
Assess the relationship between SRH and physical performance measures in middle-aged and older women in a low-income setting of Brazil.
This is a cross-sectional study of 571 middle-aged (40-59 years old) and older (60-80 years old) women living in Parnamirim and Santa Cruz in the Northeast region of Brazil. Participants reported their health status and were allocated to the "SRH good" or "SRH poor" groups. The physical performance evaluation included: handgrip strength, one-legged balance with eyes open and closed and chair stand test. The relationship between SRH and physical performance for middle-aged and older women was assessed by quantile regression (modeling medians) adjusted for potential confounders (age, socioeconomic variables, body mass index, menopause status, age at first birth, parity, chronic conditions and physical activity).
Middle-aged women from the "SRH good" group presented better physical performance with 1.75 kgf stronger handgrip strength (95% CI [0.47-3.02]; = 0.004), 1.31 s longer balance with eyes closed ([0.00-2.61]; = 0.030), and they were 0.56 s faster in the chair stand test ([0.18-0.94]; = 0.009) than those who reported "SRH poor". No association was found for balance with eyes open. For older women, there was no evidence of associations between physical performance and SRH.
This study showed that SRH is significantly associated with objective measures of physical performance in a sample of low-income middle-aged women. SRH can be an important tool to indicate the need for further evaluation of physical performance among middle-aged women and can be particularly useful for low-income communities.
自我评估健康状况（SRH）被视为衡量个人健康状况的一种简单且有效的方法，因为它与不良健康结果相关联，包括老年人群身体机能较差。然而，在低收入和中等收入环境中研究这些关联的研究很少，特别是针对中年人群。了解SRH在低收入人群中与客观健康指标之间的有效性，有助于在卫生政策和战略方面做出决策，尤其是在资源匮乏的环境中。
评估巴西低收入环境中中年及老年女性的SRH与身体机能指标之间的关系。
这是一项对居住在巴西东北部帕尔纳米林和圣克鲁斯的571名中年（40 - 59岁）及老年（60 - 80岁）女性进行的横断面研究。参与者报告了她们的健康状况，并被分为“SRH良好”或“SRH较差”组。身体机能评估包括：握力、睁眼和闭眼单腿平衡以及从椅子上站起测试。通过对潜在混杂因素（年龄、社会经济变量、体重指数、绝经状态、初产年龄、产次、慢性病和身体活动）进行调整的分位数回归（对中位数进行建模），评估中年及老年女性的SRH与身体机能之间的关系。
“SRH良好”组的中年女性在身体机能方面表现更好，握力比报告“SRH较差”的女性强1.75千克力（95%置信区间[0.47 - 3.02]；P = 0.004），闭眼平衡时间长1.31秒（[0.00 - 2.61]；P = 0.030），从椅子上站起测试快0.56秒（[0.18 - 0.94]；P = 0.009）。睁眼平衡方面未发现关联。对于老年女性，没有证据表明身体机能与SRH之间存在关联。
本研究表明，在低收入中年女性样本中，SRH与身体机能的客观指标显著相关。SRH可以作为一个重要工具，表明需要对中年女性的身体机能进行进一步评估，并且对低收入社区可能特别有用。
