The Ohio Behavioral Risk Factor Surveillance System (BRFSS) is housed within the Community Health Assessments Section; Bureau of Health Surveillance, Information and Operational Support; Division of Prevention at the Ohio Department of Health (ODH). Since 1984, ODH has entered into a yearly cooperative agreement with the Centers for Disease Control and Prevention (CDC) to develop and implement the BRFSS survey in Ohio. Currently, Ohio is one of 54 states and territories working with the CDC to obtain data regarding the prevalence of selected behaviors among adults, i.e. persons age 18 years and older, that increase the risk of certain diseases and injuries.


Sampling Selection
The Ohio BRFSS uses telephone surveys to collect data. A random digit dial two-stage sampling method (Disproportionate Stratified Sample design) is used to obtain a sample representative of Ohio residents. Upon reaching a residence and verifying the telephone number, the appropriate respondent is randomly selected. The total Ohio sample size obtained was 8,327 persons in 1999-2001. This is the number of adults who completed interviews and provided necessary survey information. The population was similar to the age, income and racial distribution of the population of Ohio.
Data Analyses  Most counties did not provide a sufficient sample size to calculate specific adult county resident prevalence except for Cuyahoga, Franklin, Hamilton, Lucas, Mahoning, Montgomery, and Summit Counties. Therefore, individual county prevalence estimates were calculated for these seven counties, and the remainder counties were combined into 5 different regions to obtain a sufficient sample size (See map below). For example, the Northeast region consists of Ashtabula, Ashland, Columbiana, Cuyahoga, Geauga, Holmes, Lake, Lorain, Medina, Mahoning, Portage, Stark, Summit, Trumbull and Wayne Counties. Specific prevalence estimates were made for Cuyahoga, Mahoning and Summit Counties, but Ashtabula, Ashland, Columbiana, Geauga, Holmes, Lake, Lorain, Medina, Portage, Stark, Trumbull and Wayne Counties were combined to obtain a more stable prevalence estimate. The region estimate was then used as a proxy for the estimate in each county in this area.
Tables included in this report show the 95% confidence intervals associated with all reported percentage. Prevalence was not calculated if the sample size is too small to provide a reliable estimate (i.e., n < 50).

Respondents who answered "donít know/not sure" or refused the question were excluded from the analyses. To assure that prevalence estimates are representative of Ohioís population, data were weighted/adjusted for age, gender, and probability of selection (e.g., number of adults and number of telephone numbers in the household).

- Current cigarette smokers: adults who reported smoking at least 100 cigarettes in their lifetime and currently smoke everyday or some days.
- Binge drinking: consuming five or more drinks of alcohol (beer, wine, wine coolers, cocktails, or liquor) on at least one occasion during the past month.
- Physical inactivity: outside of job duties, no reported leisure time physical activities done for exercise or recreation during the past month.
- Regular and vigorous activity: any physical activity or pair of physical activities that requires rhythmic contraction of large muscle groups at 50% of functional capacity for 20 or more minutes three or more times per week.
- Responsible sexual behavior (female): sexually active, unmarried females aged 18 to 44 years who reported using a condom at last sexual intercourse.
- Responsible sexual behavior (male): sexually active, unmarried males aged 18 to 49 years who reported using a condom at last sexual intercourse.
- Children wearing bike helmets: denominator is children aged 5-15 who have ever ridden a bicycle.
- Women 18+ Pap smear within past 3 Years: denominator is women 18 years and older who had never had a hysterectomy.
