Although higher optimism has been linked to an array of positive health outcomes, the association between optimism and incidence of stroke remains unclear, especially among older adults. We examined whether higher optimism was associated with a lower incidence of stroke.
Prospective data from the Health and Retirement Study--a nationally representative panel study of American adults aged>50 years--were used. Analyses were conducted for a 2-year follow-up on the subset of 6044 adults (2542 men, 3502 women) who were stroke-free at baseline. Analyses adjusted for chronic illnesses, self-rated health, and relevant sociodemographic, behavioral, biological, and psychological factors.
Higher optimism was associated with a lower risk of stroke. On an optimism measure ranging from 3 to 18, each unit increase in optimism was associated with an age-adjusted OR of 0.90 for stroke (95% CI, 0.84 to 0.97; P<0.01). The effect of optimism remained significant even after fully adjusting for a comprehensive set of sociodemographic, behavioral, biological, and psychological stroke risk factors.
Optimism may play an important role in protecting against stroke among older adults.
尽管更高的乐观情绪与一系列积极的健康结果有关，但乐观情绪与中风发病率之间的关系尚不清楚，尤其是在老年人中。我们研究了更高的乐观情绪是否与较低的中风发病率有关。
使用来自健康与退休研究（一项针对 50 岁以上美国成年人的全国代表性小组研究）的前瞻性数据。在基线时无中风的 6044 名成年人（2542 名男性，3502 名女性）的 2 年随访中进行了分析。分析调整了慢性病、自我报告的健康状况以及相关的社会人口统计学、行为、生物学和心理因素。
更高的乐观情绪与中风风险降低有关。在乐观程度从 3 到 18 的范围内，乐观程度每增加一个单位，中风的年龄调整比值比为 0.90（95%CI，0.84 至 0.97；P<0.01）。即使在充分调整了社会人口统计学、行为、生物学和心理中风风险因素的综合数据集后，乐观情绪的影响仍然显著。
乐观情绪可能在保护老年人免受中风方面发挥重要作用。
