The objective of the study was to examine whether cold climate is associated with poorer health in diverse Arctic populations. With climate change increasingly affecting the Arctic, the association between climate and population health status is of public health significance. The mean January and July temperatures were determined for 27 Arctic regions based on weather station data for the period 1961-1990 and their association with a variety of health outcomes assessed by correlation and multiple linear regression analyses. Mean January temperature was inversely associated with infant and perinatal mortality rate, age-standardized mortality rate from respiratory diseases, and age-specific fertility rate for teens and directly associated with life expectancy at birth in both males and females, independent of a variety of socioeconomic, demographic, and health care factors. Mean July temperature was also associated with infant mortality and mortality from respiratory diseases, and with total fertility rate. For every 10 degrees C increase in mean January temperature, the life expectancy at birth among males increased by about 6 years and infant mortality rate decreased by about 4 deaths/1,000 livebirths. Cold climate is significantly associated with higher mortality and fertility in Arctic populations and should be recognized in public health planning.
本研究旨在探讨寒冷气候是否与多样化的北极人群的健康状况较差有关。随着气候变化日益影响北极地区，气候与人口健康状况之间的关联具有公共卫生意义。根据 1961-1990 年气象站数据，确定了 27 个北极地区的 1 月和 7 月平均气温，并通过相关分析和多元线性回归分析评估了其与各种健康结果之间的关系。1 月平均气温与婴儿和围产期死亡率、呼吸道疾病标准化死亡率、青少年特定生育率呈负相关，与男性和女性的出生时预期寿命呈正相关，这与各种社会经济、人口和医疗保健因素无关。7 月平均气温也与婴儿死亡率和呼吸道疾病死亡率以及总生育率有关。1 月平均气温每升高 10°C，男性的出生时预期寿命增加约 6 年，婴儿死亡率降低约 4 人/千例活产。寒冷的气候与北极地区较高的死亡率和生育率显著相关，在公共卫生规划中应予以重视。
