Abstract

This study assessed the association between gender, race, ethnicity, and weight status in colorectal cancer (CRC) screening. Data for 7,088 respondents to the 2005 National Health Interview Survey, who were 50-80 years of age, were analyzed. Obese and overweight individuals were compared to their normal weight peers to identify variables associated with overall CRC screening. Multivariable regression analyses were performed to determine if weight status (i.e., normal weight, overweight, and obese) was significantly associated with overall CRC screening within racial/ethnic-gender respondent subgroups (i.e., white males, white females, black males, black females, Hispanic males, Hispanic females). Overall CRC screening rates among NHIS respondents were as follows: white males (58%), white females (58%), black males (44%), black females (48%), Hispanic males (39%), and Hispanic females (37%). Within these subgroups, multivariable analyses showed that CRC screening rates did not differ significantly for survey respondents who were overweight or obese as compared to those who were normal weight. This study is the first to report on the association of weight status and overall CRC screening in NHIS-respondent racial/ethnic-gender subgroups. Although screening rates differed across respondent subgroups, weight status did not explain screening use within the groups.
