NYC HANES 2013-2014: Accomplishments, Challenges, and Lessons Learned From Conducting a Population Health Surveillance Study
Methods: NYC HANES was a population-based, cross-sectional survey of NYC adults, with a three-stage cluster sampling design, and a questionnaire, physical exam, and specimen collection. Interviews were conducted in English, Spanish, Russian, and Chinese, with telephone translation for other languages. Portable centrifuges and overnight shipping helped ensure timely processing of biological specimens. Participants were compensated $100, increased to $200 the last two weeks of the study. Outreach efforts included key messages stressing both personal and civic benefits, a website and video, a Facebook page, contacting building management, neighborhood blog postings and live presentations, and endorsements from official and community leaders.
Results: Final sample size was 1545 participants, with a response rate of 36%. A total of 1236 (82%) participants completed the study at home, and 1230 provided blood samples (80%). The increased incentive improved response: 78 interviews (5.1% of the total) were completed during the last 12 days of the study, compared with 121 (7.8%) the previous 30 days. Overall response rate was below that achieved in 2004 in spite of the modified study design and innovative outreach. Possible explanations include difficulty gaining access to locked buildings, lower acceptance of unsolicited home visits, greater reluctance toward surveys, remote supervision of data collection, and insufficient incentives.
Conclusions: Lessons from the second NYC HANES should be useful to others planning field surveys or biospecimen collection. While declines in response rates observed in NYC HANES mirror those of surveys nationwide, participants responded positively to the home interviews and specimen collection. To reach targeted sample sizes, though, researchers must be increasingly resourceful.
