TUESDAY, July 16, 2019 (HealthDay News) -- From 2000 to 2015, colonoscopy rates increased among those aged 45 to 54 years, while colorectal cancer incidence increased among those aged 40 to 54 years, according to a study published online July 11 in the Journal of Medical Screening.
Stacey A. Fedewa, Ph.D., from the American Cancer Society in Atlanta, and colleagues used nationally representative data for 53,175 respondents aged 40 to 54 years in the National Health Interview Survey from 2000 through 2015 to examine changes in colonoscopy rates. During the same period, colorectal cancer incidence rates and incidence rate ratios were estimated.
The researchers found that past-year colonoscopy rates were stable during 2000 to 2015 among respondents aged 40 to 44 years, varying from 2.3 to 3.5 percent. From 2000 to 2015, colonoscopy rates increased from 2.5 to 5.2 percent among those aged 45 to 49 years and from 5.0 to 14.1 percent among those aged 50 to 54 years. The incidence rates of colorectal cancer increased in those aged 40 to 44, 45 to 49, and 50 to 54 years during 2000 to 2015 (incidence rate ratios, 1.28, 1.15, and 1.17, respectively).
"Future studies should examine reasons for the rising colorectal cancer incidence rates in young adults and monitor colonoscopy rates among adults aged 45 to 49 to assess the impact of recent American Cancer Society guidelines lowering the age of recommended screening," the authors write.
