The aim of the current study is to examine gender differences in mobility disability among older people in Nigeria, and to explore factors associated with gender differences in mobility disability in later life. Data were used from the first (2010-2011) wave of the Nigeria General Household Survey-Panel, which included 3586 respondents aged 50 years and above. Mobility disability was assessed as self-reported difficulty in walking 100 m, walking 1 km, walking uphill, running, bending or stooping, and climbing stairs. Regression analyses were used to estimate the extent to which socio-demographic conditions contribute to gender differences in mobility disability. We observed a higher prevalence of mobility disability among women compared to men (20.1 vs. 12.5 %, < 0.001). The prevalence ratios (PR) of mobility disability for women versus men was 1.61 (95 % CI 1.38-1.88, < 0.001); after adjusting for age, marital status, place of residence, self-reported health status and cognitive difficulties, the PR was 1.55 (95 % CI 1.30-1.85, < 0.001). In the fully adjusted model, mobility disability still remained significantly higher among women (PR 1.60, 95 % CI 1.32-1.93, < 0.001). The marginal effects of socio-demographic and health factors were stronger for women than for men. Socio-demographic and health variables considered in this study explained between 19.3 % (men) and 22.3 % (women) of variance in mobility disability suggesting that additional factors beyond those considered in this study warrant further investigation, so that differences in mobility disability between older men and women in Nigeria can be fully understood.
本研究的目的是调查尼日利亚老年人行动不便方面的性别差异，并探讨与晚年行动不便性别差异相关的因素。数据来自尼日利亚一般家庭调查小组的第一轮（2010 - 2011年）调查，其中包括3586名年龄在50岁及以上的受访者。行动不便通过自我报告在行走100米、行走1公里、上坡行走、跑步、弯腰或俯身以及爬楼梯方面的困难来评估。采用回归分析来估计社会人口学状况对行动不便性别差异的影响程度。我们观察到，女性行动不便的患病率高于男性（20.1%对12.5%，P<0.001）。女性与男性行动不便的患病率比值（PR）为1.61（95%CI 1.38 - 1.88，P<0.001）；在调整年龄、婚姻状况、居住地点、自我报告的健康状况和认知困难后，PR为1.55（95%CI 1.30 - 1.85，P<0.001）。在完全调整模型中，女性行动不便的患病率仍然显著更高（PR 1.60，95%CI 1.32 - 1.93，P<0.001）。社会人口学和健康因素对女性的边际效应比对男性更强。本研究中考虑的社会人口学和健康变量解释了行动不便差异的19.3%（男性）至22.3%（女性），这表明本研究未考虑的其他因素值得进一步调查，以便充分理解尼日利亚老年男性和女性在行动不便方面的差异。
