295 Colonoscopy Use Among Dominicans: An Analysis of the New York City Community Health Survey (2003–2016)

Abstract

INTRODUCTION: Screening for colorectal cancer (CRC) reduces incidence and mortality. Latinos are more likely to be diagnosed with late-stage CRC than non-Latino whites, a disparity that may be partially attributed to lower rates of screening among Latinos. New York City (NYC) has the fourth largest Latino population in the U.S., with Dominicans comprising the largest subgroup (41%). The current study examines predictors of up-to-date colonoscopy use among Dominicans using the NYC Community Health Survey (NYCCHS). METHODS: The NYCCHS is an annual population-based telephone survey of New Yorkers aged 18 and older. We included all Dominicans aged 50 and older who participated in the survey from 2003–2016. The outcome of interest was up-to-date colonoscopy use, defined as having completed a colonoscopy within the past 10 years. To evaluate sociodemographic and medical predictors of colonoscopy uptake, we entered age, sex, and all factors with P < 0.10 on univariate analysis into multivariable models for each of four consecutive time periods: 2003–2008, T1; 2009–2012, T2; 2013–2014, T3; and 2015–2016, T4. The final models were determined using stepwise backward selection. RESULTS: Results for 3,237 Dominican participants are shown in Table 1. On multivariable analysis, two variables were significantly associated with colonoscopy use in three of the time periods: age ≥65 (T1, T2, T4) and having received a flu vaccine in the prior year (T1, T3, T4). Two variables were significantly associated with colonoscopy uptake in two time periods: foreign birth (T1, T4) and longer duration of residence in the US (T2, T3). Variables associated with up-to-date colonoscopy use in only one time period included having a primary care provider (T2), being unemployed (T2), self-rated poor health status (T2), residence in Queens (T3), and not drinking sugar-sweetened beverages (T3). CONCLUSION: Among Dominicans living in NYC, older age, foreign birthplace, longer duration of residence in the US, and receiving the flu vaccine were the most consistent factors associated with up-to-date colonoscopy use.
