Body mass index and up-to-date colorectal cancer screening among Marylanders aged 50 years and older.

INTRODUCTION: Overweight and obese individuals are at increased risk for developing and dying from colorectal cancer. Studies suggest that overweight and obese women are more likely to avoid or delay cancer screening. Our objective was to determine whether overweight or obese adults aged 50 years and older living in Maryland in 2002 were less likely to be up-to-date with colorectal cancer screening than normal and underweight adults. METHODS: The relationship between body mass index and colorectal cancer screening was evaluated based on responses from 3436 participants aged 50 years and older to the Maryland Cancer Survey 2002, a population-based random-digit-dial telephone survey. The survey contains self-reported information on colorectal cancer screening, height, weight, and potential confounders. Logistic regression was performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs), adjusted for age, sex, race, employment, marital status, education, area of residence, and health-care-related variables. RESULTS: Overall, 64.9% of Marylanders aged 50 and older were up-to-date with colorectal cancer screening. Compared with normal and underweight individuals, overweight individuals had similar odds of being up-to-date with colorectal cancer screening (OR, 1.05; 95% CI, 0.83-1.33). Obese individuals had slightly lower odds, but this difference was not statistically significant (OR, 0.84; 95% CI, 0.65-1.09). Recommendation by a health care provider for colorectal cancer screening was strongly associated with up-to-date colorectal cancer screening (OR, 36.7; 95% CI, 28.7-47.0). CONCLUSION: Our study shows no statistically significant association between body mass index levels and up-to-date colorectal cancer screening. We recommend that physicians and other health care providers increase up-to-date colorectal cancer screening rates in the population by referring their patients for appropriate screening.

Oral cancer exams among cigarette smokers in Maryland.

BACKGROUND: Current and former smokers are at increased risk to develop oral cancer. This analysis was performed to determine whether current and former smokers are more likely to undergo an exam for oral cancer than non-smokers. METHODS: The Maryland Cancer Survey performed in 2002 was a population-based random digit dial, statewide survey on cancer screening and risk behaviors, targeting adults aged 40 years and older. The dataset contains self-reported information on oral cancer examinations, current smoking status, and health care access information for 4840 Maryland residents. RESULTS: 2062 (42.6%) of Marylanders aged 40 years and older reported ever having had an oral cancer examination. Dentists and dental hygienists performed 90.9% of the exams. Current and former smokers were no more likely than those who have never smoked to have ever had the examination (adjusted OR = 1.02, 95% CI = 0.85-1.23 and OR = 1.09, 95% CI = 0.94-1.25, respectively). Other predictors associated with having an oral cancer exam included having more than a high school of education, being female, non-black, being in good to excellent health, and having a recent physical exam. Having visited the dentist in the last year had the highest odds of having ever had an oral cancer exam. CONCLUSIONS: Current and former smokers are a high-risk group who need to be targeted for oral cancer exams by dental professionals and primary care physicians.
