Study Highlights How Flooding Affects Older Adults' Health

Recent research analyzing 17 years of data from Medicare hospitalization claims alongside major flood events reveals significant health impacts on adults aged 65 and older. The study, conducted by researchers from Harvard T.H. Chan School of Public Health, Ohio State University, University of Wisconsin–Madison, and Columbia University Mailman School of Public Health, was published in the journal Lancet Planetary Health. It examined over 4.5 million hospitalizations across 72 major flood events, identifying increases in skin diseases, nervous system disorders, injuries, and poisonings in the elderly following floods.

The findings show that hospitalization rates for skin conditions rose by 3.1%, nervous system diseases by 2.5%, musculoskeletal issues by 1.3%, and injuries or poisoning by 1.1%. Notably, communities with lower Black resident populations experienced more severe effects for nervous system diseases (up to 7.6%), while areas with higher Black populations faced more pronounced impacts on skin diseases (6.1%) and mental health.

Older adults are especially vulnerable to flood-related health problems due to factors like weakened immune systems, limited mobility, pre-existing health conditions such as dementia, and poor access to medical services. Health issues from floods can include exposure to contaminated water sources leading to skin infections, traumatic brain injuries causing seizures, and delays in seeking care resulting in worse outcomes for conditions like musculoskeletal injuries.

The study emphasizes that racial disparities may influence the severity of health impacts, potentially due to differences in housing quality, access to emergency resources, and implicit biases in healthcare. To mitigate these risks, experts recommend targeted outreach, improved evacuation plans, and infrastructure adaptations such as elevating essential healthcare facilities and deploying mobile medical units or drone-delivered supplies. Implementing community alert systems and harnessing telemedicine could also help protect vulnerable elderly populations during floods.

This research sheds light on the diverse, previously underrecognized health consequences of flooding on older adults and offers guidance for building resilience against climate-related disasters. Protecting this at-risk group requires coordinated efforts in preparedness, healthcare infrastructure, and community engagement.
