目的：评估为墨西哥尤卡坦州 70 岁及以上的个人提供补充收入的干预措施对认知功能标记（立即和延迟单词回忆）的短期（6-9 个月）影响和中介机制。方法：使用在治疗和对照地点通过实验收集的基线和随访数据进行回归调整的双重差异 (DID) 分析。结果：干预措施改善了男性和女性的立即和延迟回忆得分。我们发现对痴呆症危险因素、抑郁症和日常生活活动 (ADL) 的诊断没有影响。该干预措施增加了医疗保健的使用，减少了男性和女性的贫血，并改善了男性的粮食供应。对认知结果的影响是由男性和女性的医疗保健使用情况以及男性的食物供应情况介导的。讨论：在低收入和中等收入国家，老年人的补充收入可能是通过增加粮食安全和医疗保健利用率来改善认知功能的有效策略。
Objective:To estimate the short-run (6-9 months) impact and mediating mechanisms of an intervention providing supplemental income to individuals 70 years and above from the Mexican state of Yucatan on markers of cognitive functioning (immediate and delayed word recall).Method:Regression-adjusted difference-in-differences (DID) analysis using baseline and follow-up data collected at treatment and control sites from an experiment.Results:The intervention improved immediate and delayed recall scores for men and women. We found no effects on diagnoses of dementia risk factors, depression, and activities of daily living (ADLs). The intervention increased health care use and decreased anemia for men and women, and improved food availability for men. The effects on cognitive outcomes were mediated by health care use for both men and women, and food availability for men.Discussion:In low- and middle-income countries, supplemental income for elderly may be an effective strategy to improve cognitive function by increasing food security and health care utilization.
