3. Background

4. BACKGROUND (1) What is the Community Health Survey?
Cross-sectional telephone survey on the health of New Yorkers
Conducted by the NYC Department of Health and Mental Hygiene (DOHMH)
Complex sample survey weights are available to produce neighborhood and city-wide estimates
Population and geography
Non-institutionalized adults aged 18 and older who live in a household with a landline telephone or a cell phone in New York City (the five borough area)
Annual sample of approximately 8,500 randomly selected adults
Data on HIV+ persons is not available

5. BACKGROUND (2) Timeframe of available data Accessibility of data
Data collected since 2002
Starting in 2009, expanded the eligible population from households with a landline to also include cell-only households
Accessibility of data
Public use dataset are available with single year weights
Users can request multi-year weights from the DOHMH:

6. Content

7. CONTENT (1) What’s in the CHS data set
125 questions covering the following health topics: general health status and mental health, health care access, cardiovascular health, diabetes, asthma, immunizations, nutrition and physical activity, smoking, HIV, sexual behavior, alcohol consumption, cancer screening and other health topics.
A core group of demographics variables are included every year to facilitate weighting and comparisons among different groups of New Yorkers.

8. CONTENT (2) HIV-related indicators HIV testing
Tested in the past 12 months
Ever tested

9. How to use the CHS data

10. HOW TO USE THE DATA (1)
Proportion of NYC residents tested in the last 12 months

11. HOW TO USE THE DATA (2)
Expanded HIV testing is associated with decreases in late HIV diagnosis
Ransome, Yusuf, et al. "Expanded HIV testing coverage is associated with decreases in late HIV diagnoses." AIDS 29.11 (2015):

12. HOW TO USE THE DATA (3) Potential use of CHS to further DSRIP PPS work
Examine trends in city-wide HIV testing or neighborhood-wide HIV testing
Examine trends in HIV testing by demographic subgroups
Compare CHS data to clinic interventions

13. Strengths and Limitations

14. STRENGTHS Population-representative sample 10+ years of data available
DOHMH provides example code for data analysis
If you need assistance with the data, you can reach out to the health department

15. LIMITATIONS What to keep in mind:
The survey sampling methodology does not capture the following groups: households without any telephone service and (prior to 2009) households that only have a cell phone.
The CHS also excludes adults living in institutional group housing, such as college dormitories.
Due to the complex sampling design of the CHS, data must be analyzed in a software program capable of handling complex survey data  (such as SUDAAN, STATA or SAS-callable SUDAAN)
Multi-year weights are only available for data years , and
At this time, survey data from cannot be combined with earlier years.
