This study examines the associations between lifecourse adversity and physical performance in old age in different societies of North and South America and Europe.
We used data from the baseline survey of the International Study of Mobility in Aging, conducted in: Kingston (Canada), Saint-Hyacinthe (Canada), Natal (Brazil), Manizales (Colombia) and Tirana (Albania). The study population was composed of community dwelling people between 65 and 74 years of age, recruiting 200 men and 200 women at each site. Physical Performance was assessed with the Short Physical Performance Battery (SPPB). Economic and social adversity was estimated from childhood adverse events, low education, semi-skilled occupations during adulthood and living alone and insufficient income in old age.
A total of 1995 people were assessed. Low physical performance was associated with childhood social and economic adversity, semi-skilled occupations, living alone and insufficient income. Physical performance was lower in participants living in Colombia, Brazil and Albania than in Canada counterparts, despite adjustment for lifecourse adversity, age and sex.
We show evidence of the early origins of social and economic inequalities in physical performance during old age in distinct populations and for the independent and cumulative disadvantage of low socioeconomic status during adulthood and poverty and living alone in later life.
本研究考察了北美洲、南美洲和欧洲不同社会中人生历程逆境与老年身体机能之间的关联。
我们使用了老年流动性国际研究基线调查的数据，该调查在加拿大金斯敦、加拿大圣阿赞、巴西纳塔尔、哥伦比亚马尼萨莱斯和阿尔巴尼亚地拉那进行。研究人群由65至74岁的社区居民组成，每个地点招募200名男性和200名女性。使用简短身体机能量表（SPPB）评估身体机能。根据童年不良事件、低教育水平、成年期半熟练职业、老年独居和收入不足来估计经济和社会逆境。
共评估了1995人。身体机能低下与童年社会和经济逆境、半熟练职业、独居和收入不足有关。尽管对人生历程逆境、年龄和性别进行了调整，但生活在哥伦比亚、巴西和阿尔巴尼亚的参与者的身体机能低于加拿大的同龄人。
我们证明了不同人群中老年身体机能方面社会和经济不平等的早期根源，以及成年期低社会经济地位、老年贫困和独居的独立和累积劣势。
