Health Indicator Report of Carbon Monoxide Detectors: Self-Reported Presence in Home

Carbon monoxide (CO) is a colorless, odorless and poisonous gas that is produced by the incomplete burning of solid, liquid and gaseous fuels. CO exposure is often the result of improper ventilation or inhalation of exhaust fumes from cars, trucks and other vehicles, generators, or gas heaters. Although CO poisoning can almost always be prevented, every year more than 500 Americans die as a result of unintentional exposure to this toxic gas, and thousands more require medical care for non-fatal poisoning. CO poisoning can be prevented by the installation and maintenance of CO detectors/alarms, and the proper maintenance of heating systems. Important guidelines: -Install battery-operated or battery back-up CO detectors near every sleeping area in your home. -Check CO detectors regularly to be sure they are functioning properly.

Data Interpretation Issues

Data from the New Jersey Behavioral Risk Factor Survey are intended to represent non-institutionalized adults in households with telephones. Data are collected using a random sample of all possible telephone numbers throughout New Jersey. Prior to analysis, data are weighted to represent the population distribution of adults by age, sex, and "race"/ethnicity. As with all surveys, however, some residual bias may result from non-response (e.g., refusal to participate in the survey or to answer specific questions) and measurement error (e.g., social desirability or recall). Attempts are made to minimize such error by use of a strict calling protocol (up to 15 calls are made to reach each household), good questionnaire design, standardization of interviewer behavior, interviewer training, and frequent, on-site interviewer monitoring and supervision.
