Abstract

BackgroundWe recently developed HOUSES, an individual housing-based socioeconomic status SES measurement for health disparities research. We assessed whether HOUSES was associated with risk of pertussis and pertussis vaccine up-to-date status in children.

MethodsThe study utilized a previous population-based case-control study cohort assembled during the 2004–2005 pertussis outbreak. We collected data on pertussis vaccine status up-to-date status at the time of the index date. Using a z-score for housing value, actual square footage, and numbers of bedrooms and bathrooms, HOUSES was formulated in continuous variable and categorized into quartiles. Vaccine up-to-date status was compared among subjects with different SES as measured by HOUSES using a chi-square test and logistic regression models.

ResultsOf the 391 eligible pediatric subjects median age of 13.1 years with male sex of 55 %, 363 93 % were successfully geocoded to formulate HOUSES index. HOUSES was not associated with the risk of pertussis p = 0.82. Pertussis vaccine up-to-date statuses were 79, 86, 83, and 94 % for children in the first the lowest SES, second, third, and fourth quartiles of HOUSES, respectively p = 0.03. HOUSES as a continuous variable was associated with pertussis vaccine up-to-date status adjusted OR: 1.15 per increment of one unit of HOUSES, 95 % CI: 1.04–1.27, p = 0.008.

ConclusionWhile HOUSES is not associated with the risk of pertussis, it predicts vaccine up-to-date status among children with different SES. HOUSES may be a useful tool for vaccine delivery research among children.
