title: Archival Version

description: The New York City Community Health Survey (CHS) is a telephone survey conducted annually by the New York City Department of Health and Mental Hygiene (DOHMH). The CHS conducted in 2009 collected information from 9,934 New York adult residents aged 18 years and older from all 5 boroughs of New York City -- Manhattan, Brooklyn, Queens, Bronx, and Staten Island. All data collected are self-report. Data are available at the level of 34 different neighborhoods, defined by ZIP code. The survey is conducted to inform health program decisions, to increase the understanding of the relationship between health behavior and health status, and to support health policy positions. Respondents were asked about their physical activity, body weight, general health, and whether they had ever had a flu shot. Multiple questions addressed respondents' smoking habits, including their current smoking status, where their last cigarette was purchased, whether they were heavy smokers, whether they tried to stop smoking for a period of time, and what, if any, aids did they use to for smoking cessation. Information was collected on respondents' colonoscopy, mammogram, and pap smear screenings, as well as hypertension, mental health distress, asthma, diabetes and depression diagnosis. Additional information was collected from those diagnosed on whether they were taking any medication to control their hypertension and mental health issues. Other topics covered included  second hand smoke, respondents' sexual identity, history and contraception usage, whether they had ever been tested for HIV, and information regarding respondents' fruit and vegetable, alcohol, water, and soda consumption. Weights were constructed at the UHF-level to allow the sample to provide neighborhood-level estimations of both individual adults and of households in New York City. The data contains a weight variable (WT9) that should be used in analyzing the data. Demographic variables include gender, age, marital status, employment status, race, poverty level, income, and education level.
description: In order to appropriately analyze CHS data, a weight (WT10_DUAL) is applied to each record. The weight consists of an adjustment for the probability of selection (number of adults in each household/number of residential telephone lines), as well as a post-stratification weight. The post-stratification weights are created by weighting each record up to the population of the UHF neighborhood, while taking into account the respondent's age, gender and race. Starting in 2009, responses were also weighted to account for the distribution of the adult population comprising three telephone usage categories (landline only, landline and cell, cell only) using data from the 2008 New York City Housing and Vacancy Survey.
description: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of 
				disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major 
				statistical software formats as well as standard codebooks to accompany the data. In addition to 
				these procedures, ICPSR performed the following processing steps for this data collection:
			   		Performed consistency checks.; Created variable labels and/or value labels.; Created online analysis version with question text.; Checked for undocumented or out-of-range codes..

					ICPSR created a unique sequential record identifier variable named CASEID for use with online analysis.Abt-SRBI, a survey research company based in New York City collects data for the CHS.Value labels for variable STRATA were given based on the convention of variable UHF.All value label information was taken from the codebook (pu_codebook_chs2009_Oct 2010) deposited with ICPSR by the Principle Investigator.
description: The 2009 CHS was a landline telephone survey of 9,934 randomly selected adults aged 18 or older living in private (noninstitutional) households in New York City. Households were contacted using random-digit dialing sample and data was collected by interviewers using a questionnaire programmed into a computer-assisted telephone interviewing system. Every year, the questionnaire is translated from English into Spanish, Russian, and Chinese. Some years, live translation services are provided by Language Line (including Hindi, Arabic, Farsi, and Haitian Creole). All data collected were self-reported.
				   		Smallest Geographic Unit: ZIP code aggregations called UHFs
description: The CHS uses a stratified random sample to produce neighborhood and citywide estimates. Strata are defined using the United Hospital Fund's (UHF) neighborhood designation, modified slightly for the addition of new ZIP codes since UHF's initial definitions. There are 42 UHF neighborhoods in NYC, each defined by several adjoining ZIP codes.
Starting in 2009, a second sample consisting of cell-only households with New York City exchanges was added. This design is non-overlapping because in the cell-only sample, adults living in households with landline telephones were screened out.
The CHS sampling frame was constructed with a list of telephone numbers provided by a commercial vendor. Upon agreement to participate in the survey, one adult is randomly selected from the household to complete the interview.
