The prevalence of frailty varies among socioeconomic groups. However, longitudinal data for the association between subjective social status and frailty is limited. In this study, we examined whether subjective social status was associated with incident frailty. Data were obtained from a 14-year cohort of Chinese men and women (N = 694) aged 65 years and older who participated in the MrOs study-a longitudinal study on osteoporosis and general health in Hong Kong. Subjective social status at baseline (2001-2003) was assessed using a 10-rung self-anchoring scale. Incident frailty at the 14-year follow-up (2015-2017) was defined as proposed by Fried and colleagues. Ordinal logistic regressions were used to examine the association between subjective social status (high, middle, or low) and incident frailty. After adjustment for age, sex, marital status, objective socioeconomic status, medical history, lifestyle, mental health, and cognitive function, subjective social status at baseline was negatively associated with risk of developing frailty over time (OR 2.3, 95% CI 1.2-4.6). In sex-stratified analysis, the social gradient in frailty was only found in men. Social inequality in frailty in men but not in women supports interventions specific to gender inequality and frailty.
衰弱的流行率在社会经济群体中有所不同。然而，关于主观社会地位与衰弱之间的纵向数据有限。在这项研究中，我们研究了主观社会地位是否与衰弱的发生有关。数据来自于一项为期 14 年的中国男女（年龄≥65 岁）队列研究（MrOs 研究），该研究是香港骨质疏松症和一般健康的纵向研究。基线（2001-2003 年）的主观社会地位采用 10 级自我锚定量表进行评估。14 年随访（2015-2017 年）时定义的衰弱发生情况按照 Fried 等人提出的标准。使用有序逻辑回归来检查主观社会地位（高、中、低）与衰弱发生之间的关联。在校正年龄、性别、婚姻状况、客观社会经济地位、病史、生活方式、心理健康和认知功能后，基线时的主观社会地位与随着时间的推移发生衰弱的风险呈负相关（OR 2.3，95%CI 1.2-4.6）。在按性别分层的分析中，仅在男性中发现了衰弱的社会梯度。男性中衰弱的社会不平等而女性中没有，这支持了针对性别不平等和衰弱的具体干预措施。
