“…Several epidemiologic studies investigated different subgroups and various heat waves-related vulnerability factors, including individual and contextual factors. The individual factors are age, sex, or socioeconomic factors such as education, ethnicity, income or social isolation [1,[3][4][5]; the environmental factors include urban design, neighbourhood and material conditions such as the availability of air conditioning [1]. These studies have seen the most significant effect in terms of mortality and morbidity of heat waves and elevated temperature on older adults, one of the most vulnerable group.…”

Background: Heat waves are correlated with increased mortality in the aged population. Social isolation is known as a vulnerability factor. This study aims at evaluating the correlation between an intervention to reduce social isolation and the increase in mortality in the population over 80 during heat waves. Methods: The study adopts a retrospective ecologic design. We compared the excess mortality rate (EMR) in the over 80 population during heat waves in urban areas of Rome (Italy), where a program to reduce social isolation was implemented compared to others where it was not implemented. We measured mortality of the summer periods from 2015 to 2019 compared with 2014 (a year without heat waves). Winter mortality, cadastral income and proportion of over 90 were included in the multivariate Poisson regression. Results: The EMR in the intervention and controls was 2.70% and 3.81%, respectively. Rate ratio 0.70 (c.i. 0.54 - 0.92, p-value 0.01). The Incidence Rate Ratio (IRR) of the interventions with respect to the controls is 0.76 (c.i. 0.59 - 0.98). After adjusting for other variables, the IRR was 0.44 (c.i. 0.32 - 0.60). Conclusions: Reducing social isolation could limit the impact of heat waves on the mortality of the elderly population.

“…Our findings are in line with results from previous studies that have analyzed heat wave-related mortality [ 2 , 5 , 9 ]. In several epidemiological studies on heat-related mortality, various subgroups have been identified as the most severely affected and defined as vulnerable [ 1 , 6 , 10 ].…”

This study aims at evaluating the correlation between an intervention to reduce social isolation and the increase in mortality in the population over 80 during heat waves.

We measured the mortality of the summer periods from 2015 to 2019 compared with 2014 (a year without heat waves).

“… 14 However, few studies have estimated the exposure-response associations between temperature and YLL. 12 , 15 , 16 , 17 , 18 , 19 , 20 , 21 Moreover, most of these studies employed the daily overall YLL as a health outcome, and did not adjust for the offset effect of population size. As a result, the city- or community-specific association between temperature and YLL cannot be simply combined.…”
