This article examines the extent of proxy reporting in the National Population Health Survey (NPHS). It also explores associations between proxy reporting status and the prevalence of selected health problems, and investigates the relationship between changes in proxy reporting status and two-year incidence of health problems.
Cross-sectional results are based on the 1996/97 NPHS Health file and General file. Longitudinal results are based on 1994/95 respondents who were still residing in households in 1996/97.
The extent of proxy reporting in the various NPHS files was computed. Prevalence estimates of selected health problems from the two 1996/97 cross-sectional files were compared. Multivariate analyses were used to estimate associations between proxy reporting status and health problems.
For several health conditions, prevalence estimates based on the 1996/97 cross-sectional Health file (where proxy reporting was less common) were significantly higher than estimates derived from the General file. Individuals whose data were proxy-reported in 1994/95 and self-reported in 1996/97 had higher odds of reporting new cases of certain health conditions.
本文考察了国民人口健康调查（NPHS）中代理报告的程度。它还探讨了代理报告状态与特定健康问题患病率之间的关联，并研究了代理报告状态的变化与健康问题两年发病率之间的关系。
横断面结果基于1996/97年NPHS健康档案和综合档案。纵向结果基于1994/95年的受访者，他们在1996/97年仍居住在家庭中。
计算了NPHS各档案中代理报告的程度。比较了1996/97年两个横断面档案中特定健康问题的患病率估计值。采用多变量分析来估计代理报告状态与健康问题之间的关联。
对于几种健康状况，基于1996/97年横断面健康档案（代理报告较少见）的患病率估计值显著高于综合档案得出的估计值。1994/95年由代理报告数据而1996/97年由自我报告数据的个体报告某些健康状况新病例的几率更高。
