ABSTRACT
OBJECTIVES@#To assess the accuracy and influential factors for hypertension prevalence based on questionnaire interview by on-site measurement.@*METHODS@#Data were from the baseline surveys for chronic diseases among residents ages ≥18 years old in 4 districts/counties of Changsha between 2013 and 2014. All surveys adopted multi-stage random sampling to select samples. The Bootstrap resampling method was used to randomly select 1 000 repeated samples with replacement to obtain robust estimate of subgroup prevalence rates. Hypertension prevalence was calculated by using the data from both questionnaire interview and on-site measurement. Using the results of on-site measurement as the golden standard, the accuracy of questionnaire interview and 95% uncertainty interval were estimated. Multivariate logistic regression was used to investigate the influential factors for the underestimated hypotension prevalence based on questionnaire interview.@*RESULTS@#The hypertension prevalence from on-site measurement among the residents in the 4 districts/counties of Changsha was significantly higher than that from questionnaire interview (prevalence ratio 1.26-2.31). Taking the results of on-site measurement as the golden standard, the sensitivity of questionnaire interview on hypotension prevalence range from 41.76% to 74.83% among the 4 districts/counties, and the specificity fell between 98.51% and 99.46%. The underestimation in questionnaire interview was more likely to occur in the youngest age group (18-34 years old), males, and residents were at lower levels of education in all 4 districts/counties.@*CONCLUSIONS@#Compared with the on-site measurement, questionnaire interview significantly under-estimate the hypertension prevalence, suggesting that the on-site measurement method should be firstly considered in epidemiological surveys for hypertension prevalence. If only the questionnaire method can be used to collect data due to conditions, it is necessary to make corresponding corrections to the questionnaire results with reference to relevant research evidence.
