This study was developed to examine whether the use of a proxy respondent influences the distribution and factors associated with health perception among older adults, as well as the mortality relative risk. The study included 28,943 and 35,040 participants from the Brazilian National Household Survey (PNAD) in 1998 and 2003, respectively, and 1,606 members of the cohort from Bambuí, Minas Gerais, Brazil. The results showed that use of proxy in the PNAD 1998 and 2003 did not modify the distribution of health perception or associated factors. The 5-year mortality rate ratio among cohort participants was higher in direct interviews with seniors (RR = 2.40) as compared to those answered by proxies (RR = 1.28), but the direction of the association was the same. These results indicate that health perception data from the PNAD can be used regardless of who answers the interview and that the association between worse health perception and mortality persisted even when perception was inferred from a proxy.
本研究旨在探讨使用代理受访者是否会影响老年人健康认知的分布及其相关因素，以及死亡相对风险。该研究分别纳入了1998年和2003年巴西全国住户调查（PNAD）的28943名和35040名参与者，以及巴西米纳斯吉拉斯州班布伊队列的1606名成员。结果显示，1998年和2003年PNAD中代理受访者的使用并未改变健康认知的分布或相关因素。与由代理回答的受访者相比，对老年队列参与者进行直接访谈时，5年死亡率比值更高（RR = 2.40），而由代理回答的受访者的5年死亡率比值为（RR = 1.28），但关联方向相同。这些结果表明，无论谁回答访谈，PNAD的健康认知数据均可使用，并且即使从代理推断出健康认知，较差的健康认知与死亡率之间的关联仍然存在。
