Assessing the Representativeness of Population-Sampled Health Surveys Through Linkage to Administrative Data on Alcohol-Related Outcomes

摘要: Health surveys are an important resource for monitoring population health, but selective nonresponse may impede valid inference. This study aimed to assess bias in a population-sampled health survey Scotland, with focus on alcohol-related outcomes. Nonresponse was assessed by examining whether rates of harm (i.e., hospitalization or death) and all-cause mortality among respondents the Scottish Surveys (from 1995 2010) were equivalent those general population, extent any varied according sociodemographic attributes over time. Data from consenting (aged 20-64 years) 6 confidentially linked death records compared counterparts. Directly age-standardized incidence lower Survey population. For all years combined, survey-to-population rate ratios 0.69 (95% confidence interval: 0.61, 0.76) 0.89 0.83, 0.96) mortality. Bias more pronounced persons residing deprived areas; limited evidence found regional temporal variation. suggests that corresponding underestimation alcohol consumption is likely be socially patterned.
