Abstract:
|
To collect information on Zika virus awareness and prevention methods in Puerto Rico, a sample of recent births was designed to provide island-wide and regionally representative estimates. Within each region, a stratified, cluster sample of women recently delivering a live birth was drawn from birth logs in hospitals with 100 or more births in 2015. Within each region-hospital stratum, days were selected using random sampling, and all women who gave birth on the selected days were included in the sample. Sampled women were approached 24-36 hours following their delivery during their hospital stay and offered the option to complete a self-administered survey on tablet or paper. Data were weighted to account for sampling design, non-response, and non-coverage. Of the 3237 eligible births during the 13-week study period, 2926 were identified from hospital birth logs. Of those identified, 2361 responded (73% response rate). Among women who responded, 74% used the tablet and 26% used the paper form. The study design and data collection methodology allowed for rapid deployment in the field and rapid analysis of survey data, which are essential in emergency response situations.
