These findings suggest that warm temperatures are associated with increased mortality in prisons, yet this vulnerable population’s risk has largely been overlooked.Ĭitation: Skarha J, Spangler K, Dosa D, Rich JD, Savitz DA, Zanobetti A (2023) Heat-related mortality in U.S. We found the greatest increase in mortality among people ≥ 65 years old, incarcerated less than one year, held in the Northeast region, and in urban or rural counties. The cumulative effect (lags 1–3) of an extreme heat day was associated with a 22.8% (95% CI: 3.3%, 46.0%) increase in suicides. Two- and three-day heatwaves were associated with increased total mortality of 5.5% (95% CI: 0.3%, 10.9%) and 7.4% (95% CI: 1.6%, 13.5%), respectively. The association between temperature and suicides was delayed, peaking around lag 3 (exposure at three days prior death). A 10☏ increase was associated with a 5.2% (95% CI: 1.5%, 9.0%) increase in total mortality and a 6.7% (95% CI: -0.6%, 14.0%) increase in heart disease mortality. The majority were male (96%) and housed in a state-operated prison (97%). There were 12,836 deaths during summer months. We also examined the association with extreme heat and heatwaves (days above the 90th percentile for the prison location) and assessed effect modification by personal, facility, and regional characteristics. Using a case-crossover approach and distributed lag models, we estimated the association of increasing temperatures with total mortality, heart disease-related mortality, and suicides. state and private prisons from 2001–2019 linked to daily maximum temperature data for the months of June, July, and August. Yet, there is scare literature on the impacts of heat among incarcerated populations. Many of the subpopulations most vulnerable to heat-related mortality are in prisons, facilities that may exacerbate temperature exposures. Rising temperatures and heatwaves increase mortality.
