The interplay between climate change and ageing: A systematic review of health indicators

39, 41, 43, 44, 46, 47, 49, 50, 53] described the impact of climate change phenomena only in morbidity, while 6 [40, 42, 45, 48, 52, 55] addressed only mortality, and 3 [38, 51, 54] addressed both indicators. The main mortality indicator was all-cause mortality (n = 7) [38, 40, 42, 45, 48, 52, 55]. These articles illustrated a significant association between climate change phenomena and increased risk of all-cause mortality. Mortality risk increased by 1.55% (95% PI: 0.17–2.95) during high- Fig 1.
