Health Indicator Report of Chronic Obstructive Pulmonary Disease (COPD) Prevalence
COPD is a serious lung disease that makes it hard to breathe and gets worse over time. COPD can cause coughing with or without large amounts of mucus, wheezing, shortness of breath, chest tightness, and other symptoms. When COPD is severe, it can cause serious, long-term disability.
NotesAll prevalence estimates are age-adjusted to the U.S. 2000 standard population.
Data SourceBehavioral Risk Factor Survey, Center for Health Statistics, New Jersey Department of Health, [http://www.state.nj.us/health/chs/njbrfs/]
Data Interpretation IssuesData for this indicator report are from the Behavioral Risk Factor Surveillance System (BRFSS), an ongoing survey of adults regarding their health-related behaviors, health conditions, and preventive services. Data are collected in all 50 states, D.C., and U.S. territories. Responses have been weighted to reflect the New Jersey adult population by age, sex, ethnicity, geographic region, marital status, education level, home ownership and type of phone ownership. The survey is conducted using scientific telephone survey methods for landline and cellular phones (with cellular since 2011). The landline phone portion of the survey excludes adults living in group quarters such as college dormitories, nursing homes, military barracks, and prisons. The cellular phone portion of the survey includes adult students living in college dormitories but excludes other group quarters. Beginning with 2011, the BRFSS updated its surveillance methods by adding in calls to cell phones and changing its weighting methods. These changes improve BRFSS' ability to take into account the increasing proportion of U.S. adults using only cellular telephones as well as to adjust survey data to improve the representativeness of the estimates generated from the survey. Results have been adjusted for the probability of selection of the respondent, and have been weighted to the adult population by age, gender, phone type, detailed race/ethnicity, renter/owner, education, marital status, and geographic area. The "missing" and "don't know" responses are removed before calculating a percentage.
DefinitionEstimated percentage of New Jersey adults (ages 18 and over) who have been diagnosed with COPD. In the United States, the term "COPD" includes two main conditions: emphysema and chronic bronchitis. Because most people diagnosed with COPD have both emphysema and chronic bronchitis, the general term "COPD" is often used.
NumeratorNumber of adults from the Behavioral Risk Factor Surveillance System who have been told by a doctor, nurse or other health professional that they have COPD, emphysema or chronic bronchitis.
DenominatorNumber of survey respondents excluding those with missing, "Don't know/Not sure," and "Refused" responses.
How Are We Doing?In 2017, the adult COPD age-adjusted prevalence in New Jersey was 5.6%. Blacks (8.0%) have higher prevalence of COPD compared to Whites (5.3%), Hispanics (5.6%) and Asians (1.8%) in the state.
