To evaluate the impact of Hurricanes Irma and Maria on 3 major chronic diseases in Puerto Rico.

San Juan Overweight Adults Longitudinal study participants were re-evaluated after Hurricanes Irma and Maria (May 2019–July 2020) for the Preparedness to Reduce Exposures and Diseases Post-hurricanes and Augment Resilience study. This study compared the prevalence and incidence of asthma, depression, and hypertension within the same 364 individuals over time.

Asthma and depression prevalence and incidence did not change significantly after the hurricanes. The prevalence of hypertension increased significantly after the hurricanes (OR = 2.2, 95% CI: 1.2, 3.9). The incidence of hypertension after the hurricanes (IR = 9.0, 95% CI: 6.5, 12.4) increased significantly compared to before the hurricanes (IR = 6.1, 95% CI: 4.5, 8.0) (age-adjusted incidence rate ratio [aIRR] = 1.4, 95% CI: 4.5, 8.0) for similar time periods.

Hurricanes Irma and Maria were associated with a significant increase in the prevalence and incidence of hypertension in this study population. Contrary to expectations, no significant increases were observed in depression and asthma prevalence after the hurricanes. Results from this study can inform better strategies to prevent and manage hypertension in the population affected by a hurricane.

To explore the health impacts of Hurricane Maria (HM) on HIV care outcomes among people living with HIV who use drugs.

Using data from an ongoing cohort study in San Juan, Puerto Rico (Proyecto PACTo), we measured differences in HIV care outcomes (viral load, viral suppression, and CD4 counts) before and after HM using assessments conducted at 6-month intervals. Generalized estimating equations were used to assess factors associated with HIV care outcomes.

All HIV care outcomes showed a deterioration from pre-HM values to post-HM values (mean viral load increased, CD4 counts decreased, and rate of viral suppression decreased) after controlling for pre-HM sociodemographic and health characteristics. In addition to HM, age (aIRR = 1·01), being homeless (aIRR = 0·78) and having health insurance (aIRR = 1·6) were independently associated with viral suppression.

219 participants completed follow-up visits between April 2017 and January 2018, before and after HM.

People living with HIV who use drugs in Puerto Rico experienced poorer HIV outcomes following HM. Socio-environmental factors contributing to these outcomes is discussed in the context of disaster response, recovery, and program planning.

Understanding the drivers of health care utilization patterns following disasters can better support health planning. This study characterized all-cause hospitalizations among older Americans after eight large-scale hurricanes.

The objective of this study was to characterize all-cause hospitalizations for any cause among older Americans in the 30 days after eight large-scale hurricanes.

A self-controlled case series study among Medicare beneficiaries (age 65+) exposed to one of eight hurricanes was conducted. The predicted probability of sociodemographic factors associated with hospitalization using logit models was estimated.

Hurricane Sandy (2012) had the highest post-hurricane admission rate, a 23% increase (incidence rate ratio [IRR] = 1.23; 95% CI, 1.22-1.24), while Hurricane Irene in 2011 had only a 10% increase (IRR = 1.10; 95% CI, 1.09-1.11). Higher likelihood of hospitalization occurring after hurricanes included being 85 or older (36.8% probability of hospitalization; 95% CI, 34.7-39.0) and being dually eligible for Medicare and Medicaid (62.8%; 95% CI, 60.7-64.9).

Planning to address the surge in hospitalization for a longer time period after hurricanes and interventions targeted to support aging Americans are needed.

Major incidents affecting large numbers of people may increase the rate of acute cardiovascular events, even among those who are not directly involved in the incident. It is hypothesized that the MV Sewol ferry disaster (South Korea) would increase the incidence of cardiovascular events nation-wide.

Data on all adult patients (>18 years) who were diagnosed with acute cardiovascular events, including acute myocardial infarction (MI), angina, and cardiac arrhythmias, were extracted from the National Emergency Department Information System (NEDIS) from March 15 through June 17, during the years 2011-2014 (four weeks before to eight weeks after the event date). Poisson regression models were used to calculate the incidence rate ratios (IRRs) comparing the weekly changes in the occurrences of cardiovascular events from the week of the Sewol event (April 16-22, 2014) to eight weeks after the disaster (June 11-17, 2014), using the one-month period before Sewol as a reference period (March 15-April 15), adjusting for calendar years (years 2011-2014) and environmental factors.

During the study periods, cardiovascular events were identified in 73,823 patients. Compared to the reference period, the week of the Sewol disaster and the three weeks after the disaster showed a significant increase in the number of acute cardiovascular events, IRRs of 1.09 (95% CI, 1.03-1.15) and 1.08 (95% CI, 1.02-1.15), respectively (P <.01 for both). In particular, there was 21% increase in incidence of arrhythmia (IRR = 1.21; 95% CI, 1.02-1.44; P = .03) during the week of the Sewol disaster compared with the reference period.

This study showed a significant increase in the incidence of acute cardiovascular events during the week of, and the three weeks after, the Sewol ferry disaster in 2014. These additional cardiac emergencies may be triggered by emotional stressors related to the event, highlighting the public health importance of indirect exposure to a tragic catastrophe.
