ABSTRACT
Background: Incidence of cancer is constantly increasing in the United States, and Puerto Rico is no exception. The island is currently experiencing low birth rates, signifying that its population is primarily composed of aging citizens that experience a growing need for access to healthcare and medical literature, especially in those with cancer. In this study, we aimed to characterize an aging Puerto Rican cohort with a diagnosis of cancer. Method(s): A questionnaire with sociodemographic and medical inquiries was administered to participants receiving an mRNA vaccine at a COVID-19 vaccination clinic between December 2020 and June 2021. Participants of age 60+ with a diagnosis of cancer, along with their comorbidities, were identified. Multivariate analyses were executed. This study is IRB approved. Result(s): A total of 100 aging participants with a diagnosis of cancer were included: 55 were female and 45 were male, with a mean age of 72.70+/-8.07 (age range: 61-95). When assessing race, participants identified as follows: 68% White, 23% Black or African American, 8% other race, and 1% American Indian or Alaska Native. Concerning ethnicity, 97% identified as Hispanic or Latino, while 3% did not regard themselves as such. When evaluating the cancer diagnoses provided, 27% of female participants had breast cancer and 7% had some form of gynecologic malignancy. Whereas, in males, 42% indicated a diagnosis of prostate cancer. Regarding concomitant comorbidities, 45% of participants had hypertension, 30% had diabetes mellitus, 18% had hypothyroidism, 15% had asthma, and 3% had chronic obstructive pulmonary disease. There was no statistically significant difference when comparing sex and prevalence of concomitant diabetes mellitus or hypertension (p=0.2125). There was also no statistically significant difference when assessing racial identity and presence of concomitant diabetes mellitus or hypertension (p=0.7373). Out of 91 participants who answered the health insurance inquiry, 82% possessed private insurance, 13% had public insurance, and 4% did not have insurance. There was no statistically significant difference when assessing private, public, or no health insurance status and the presence of concomitant diabetes mellitus or hypertension (p=0.9086). Conclusion(s): Data evidenced a diverse aging Puerto Rican cohort with cancer, showing a predominance in prostate cancer in men and breast cancer in women. Analysis suggested that the presence of concomitant diabetes mellitus or hypertension in an aging population with cancer was not linked to sex or racial identity. Additionally, the type or lack of health insurance did not influence the prevalence of concomitant diabetes mellitus or hypertension. Characterizing the aging Hispanic population in Puerto Rico and the United States is important, as these studies could be beneficial in the future approach, understanding and treatment of this population with historically limited medical data available.
