Abstract A114: Assessing the impact of extreme climate weather events on cancer patients in Puerto Rico: A cross-sectional study

Abstract

Abstract BACKGROUND: Island communities such as Puerto Rico (PR) are profoundly impacted by climate extremes. Patients with chronic disease, particularly cancer, have unique needs and challenges in the aftermath of extreme weather events. Understanding cancer patients’ barriers, knowledge, risks, and vulnerabilities are essential to develop equitable adaptation strategies. This research aims to investigate the perceptions and experiences of cancer patients associated with extreme weather events over the past 10 years in Puerto Rico (PR). METHODS: We conducted a cross-sectional study via survey questionnaires (April 22, 2023-June 8, 2023) among adults aged ≥21 years from Puerto Rico who are cancer patients/survivors (n=207). A total of 23 questions listed on the survey were used to collect information on variables of interest which included demographic characteristics, information on extreme weather event experiences, and attitude towards climate change. Using the data collected, descriptive statistics were used to describe the study population and multivariable logistic regression models were used to evaluate the associations of interest (IRB approval # 2023-04-101). RESULTS: The average age of individuals recruited is 56.3 years ±13.5 SD, 79.7% are female, 65.2% reported having additional chronic diseases, and 85.0% have more than a high-school education. Regarding extreme weather events, 99% of cancer patients and survivors reported floods, including coastal, fluvial, and urban floods, impacted their communities, 76% reported tropical cyclones impacted their residences and communities, and 72% reported extreme heat impacted both their residences and communities in the last 10 years. Additionally, the most common problems encountered in the aftermath of these extreme weather events were water (88.4%) and electricity service interruption (91.4%), as well as water (88.9%) and electricity service interruption (77.1%). Most participants reported feeling very and extremely worried about their health in the face of climate change (75.0%) and feeling concerned about climate change (85.0%). After adjusting for age, sex, and education, logistic regression models showed that participants with more than one cancer type were more likely to be worried about their health in the face of climate change (OR=2.40,95% CI=1.06-5.35). CONCLUSION: Study findings highlight the burden of extreme weather events and the problems encountered in the aftermath of such events on cancer patients in Puerto Rico. This population expresses concern and worry about climate change and their health, respectively. This information is important for cancer control and emphasizes the need for targeted interventions and management strategies to remove detrimental and avoidable impacts on cancer populations.
