Abstract Introduction: Organized Pap test screening programs have led to a dramatic decrease in cervical cancer incidence in the U.S. and other developed countries. However, the success of screening relies on subsequent attendance for colposcopy and other follow-up procedures among women with an abnormal Pap test. Timely follow-up to colposcopy is a common problem in many populations, especially ethnic minorities and the medically underserved. The purpose of this study was to identify characteristics associated with timely follow-up to colposcopy among Hispanic women living on the Texas-Mexico border. Methods: We analyzed data on 244 Hispanic patients attending a colposcopy clinic at an academic medical center in El Paso, Texas. The dichotomous outcome variable was timely follow-up to colposcopy following an abnormal Pap. Specifically, participants were considered to have timely follow-up if the interval between the date of their last abnormal Pap test and the date of their colposcopy was 90 days or less. A generalized linear model was fit using a binomial distribution and log link. Risk ratios (RR), 95% confidence intervals (CI), and P values for an optimal interval were calculated from this log-binomial model. Results: Overall, 115 (47.1%) of women were born in Mexico. The median age was 30.9 years (52.9% of the sample was 30 years or older), 15.6% had completed 4 or more years of college 50.4 % were participants in the Breast and Cervical Cancer Services (BCCS) program, 47.1% were more acculturated versus less acculturated according to the Marín Short Acculturation Scale for Hispanics, 13.5% had an immediate family member who had developed cervical cancer, 23.4% had smoked at least 100 cigarettes in her life, approximately 16% had a Pap smear with one of the following results: atypical squamous cells where a high-grade squamous intraepithelial lesion (SIL) can't be excluded, high-grade SIL, cervical cancer. Overall, 160 of the 244 women (65.6%) had timely follow-up to colposcopy. No associations were detected between timely follow-up and acculturation, education, smoking history, family history of cervical cancer, Pap smear grade, and BCCS participant status. Women who were 30 years of age or older were 33% more likely to have an optimal interval than younger women after adjusting for the remaining variables (RR=1.33, 95% CI: 1.09-1.63, P=0.01). Conclusions: Over one-third of Hispanic women in our sample did not obtain timely follow-up to colposcopy following an abnormal Pap. Consistent with other studies, older women (age ≥30 years in our study) were more likely than younger women to have timely follow-up. Further research is needed to better understand barriers to timely follow-up to colposcopy among Hispanic women seeking care on the Texas-Mexico border.
