title: Gastric cancer screening compliance is influenced by the weight status.
abstract: Obesity is associated with decreased compliance with cancer screening, but with an increased risk for cancer development. However, the relationship between weight status and compliance with stomach cancer screening has not been not studied as yet. We examined men and women aged between 40 and 80 years from the 4th Korea National Health and Nutrition Examination Survey from 2007 to 2009. BMI was classified into ≤18.4 kg/m (underweight), 18.5-22.9 kg/m (normal), 23-24.9 kg/m (overweight), 25.0-29.9 kg/m (moderate obesity), and ≥30.0 kg/m (severe obesity). Screening compliance was defined as undergoing stomach cancer screening every 2 years with either gastroscopy or upper gastrointestinal series. The overall screening rates of stomach cancer were 43.2 (0.9)% for men and 43.4 (0.8)% for women. After adjustment for covariates, the screening rates were higher in overweight men (adjusted odds ratio, 1.19; 95% confidence interval, 0.98-1.44), with a marginal significance, and significantly lower in women with severe obesity (adjusted odds ratio, 0.55; 95% confidence interval, 0.40-0.76). The difference was mainly driven by the lower acceptance of gastroscopy rather than upper gastrointestinal series. In conclusion, obesity is associated with lower compliance with stomach cancer screening in Korean women. Therefore, new strategies need to be developed to improve the cancer screening compliance in obese women.
