@#【Objective】To explore
colonoscopy adherence and related factors among preliminary screened-positive
population in Guangzhou. 【
Methods】This study was a part of the Guangzhou
Community-based
Colorectal Cancer Screening Program. We retrospectively analyzed the 1-year follow-up data of
population aged 50~74 years old and positive in preliminary
colorectal cancer screening in 2015. Kaplan- Meier
method was used to describe the respond
time to
colonoscopy examination. Cox
proportional hazard model was performed to identify factors associated with
colonoscopy adherence. The effect of studied factors on
colonoscopy adherence was reported according to
hazard ratio(HR).【Results】 A total of 18 604 preliminary screened-positive residents were included ,among whom 4 014 completed
colonoscopy examination within one year,with a
colonoscopy adherence of 21.6% . Colorectal lesions were found in 2 012 cases (50.1%),of which 96(2.4%)were
colorectal cancers. The adherence of 1 month,3 months and 6 months were 9.7% ,15.8% ,and 18.6% respectively. Multivariate Cox
regression analysis showed that those
who were
female ,in older age ,
unmarried/
widowed/
divorced,without
health insurance,and had a
history of chronic
cholecystitis or
cholecystectomy were less likely to undergo
colonoscopy;while those
who were
fecal occult blood test- positive,had
colonoscopy preferential
policies,worked in
government or public institution,had medical
insurance for urban
workers,had a
history of chronic
diarrhea,a
history of chronic
constipation,a
history of mucous and/or
blood stool,and a
history of bad
life incidents were more likely to undergo
colonoscopy. 【Conclusions】 This study suggested that the
colonoscopy adherence of preliminary screened- positive
population in Guangzhou was low and such low adherence was associated with different factors.
Community health workers should timely
track the completion of
colonoscopy of preliminary screened-positive residents , and take targeted
measures to promote
colonoscopy adherence.
