Temporal Trends in Fecal Occult Blood Test: Associated Factors (2009-2017). Int J Environ Res Public Health. 2019 Jun 14;16(12):2120http://hdl.handle.net/10668/14130A cross-sectional study with 27,821 records of non-institutionalized people in Spain aged between 50-69 years old (59.94 ± 5.8 years), who participated in the European Health Survey in Spain (2009, 2014) and National Health Survey (2011/12, 2017). Fecal occult testing, the reason for performing the test, age, sex, nationality, social status, marital status, education level, body mass index (BMI), and place of residence. Overall, 54% were women, 93.9% were Spanish, 47.8% had a secondary study, and 66.4% were married. Across the years, the rate of the fecal occult blood test (FOBT) increased significantly (p< 0.001). This increase can be accounted for a letter campaign advising testing (45%, p < 0.001). FOBT was associated with more age (odds ratio—OR 1.04, 95% confidence interval—CI 1.04–1.05, p < 0.001), Spanish nationality (OR 1.91, 95% CI 1.25–2.93, p = 0.003), being married (OR 1.13, 95% CI 1.02–1.25, p = 0.025), having a higher level of education (OR 2.46, 95% CI 2.17–2.81, p < 0.001), belonging to high social classes (OR 1.35, 95% CI 1.12–1.64, p = 0.001), and BMI <25 (OR 1.72, 95% CI 1.25–2.37). Frequency of FOBT has increased in recent years. Performing FOBT is associated with age, nationality, marital status, higher education level, and social class.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/SpainCancer screeningColorectal cancerPublic healthAgedColorectal neoplasmsCross-sectional studiesFemaleHealth surveysHumansMaleMass screeningMiddle agedOccult bloodOdds ratioSpainresearch article31207996open accessEncuestas epidemiológicasEspañaEstudios transversalesNeoplasias colorrectalesOportunidad relativaSangre ocultaTamizaje masivo10.3390/ijerph161221201660-4601PMC6616453https://www.mdpi.com/1660-4601/16/12/2120/pdf?version=1561008566https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6616453/pdf
