Abstract:
|
In a survey of Maryland children between 2005 and 2006, 55% of those who returned a questionnaire(collecting demo-social characteristics and self-reported oral health) participated in a screening exam(collecting objective oral health). This paper examines the differences in socio-economic and oral health status among screening examination respondents and nonrespondents and the effect of non-response on estimates of oral health. Two-sided z-tests at a significance level of 0.05 are applied for all comparisons. Population estimates of demo-social characteristics among screening examination respondents were not significantly different from nonrespondents. Although an overall low response rate may potentially bias our population estimates, if the sample is representative of the target population, then weight adjustment, stratification, and imputation at the analysis stage can limit the bias.
