The NYC Health and Nutrition Examination Survey (NYC HANES), modeled on the National Health and Nutrition Examination Survey, is a population-based, cross-sectional study with data collected from a physical examination, clinical and laboratory tests, as well as a face-to-face interview and an audio computer-assisted self-interview (ACASI). The first NYC HANES (NYC HANES I) was conducted between June 2 and December 19, 2004. The survey used a probability sample of non-institutionalized adult New York City residents (ages 20 years or older) to provide representative citywide estimates. The survey was designed using a three-stage cluster sampling plan. Of the 4,026 households randomly selected for the survey, eligibility screening questionnaires were completed for 3,388 households and 3,047 study participants were identified. Of those identified, 1,999 individuals participated in the survey, yielding a response rate of 55%. Additional details on the survey methodology are available @ NYC HANES Methodology. A second NYC HANES is being planned for 2009. Specific objectives of NYC HANES are to:

1. Estimate the number and percent of persons in the NYC population with selected diseases and risk factors;
2. Estimate citywide awareness, treatment, and control of selected diseases;
3. Estimate prevalence, awareness, treatment, and control of selected diseases among a limited set of demographic subgroups identified by race/ethnicity, gender, and broad age bands;
4. Monitor prevalence and magnitude of environmental exposures in NYC;
5. Analyze risk factors for selected diseases in NYC;
6. Establish a population-based serologic repository that can be used to explore emerging public health issues in NYC.

The New York City Department of Health and Mental Hygiene, with support from the National Center for Health Statistics, conducted NYC HANES I to improve disease surveillance and establish citywide estimates for several previously unmeasured health conditions from which reduction targets could be set and incorporated into health policy planning initiatives. NYC HANES I also provides important new information about the prevalence and control of chronic disease precursors, such as undiagnosed hypertension, hypercholesterolemia, and impaired fasting glucose, which allow chronic disease programs to monitor more proximate health events and rapidly evaluate primary intervention efforts. Study findings are used by the public health community in New York City, as well as by researchers and clinicians, to better target resources to the health needs of the population.
