One might expect prevalence of asthma to affect rates of mortality due to asthma. In France, asthma prevalence at 1350 m is less than at sea level. Calculation of asthma mortality rates for blacks and whites 5 to 34 years of age in 1980 for counties in the USA with populated places at elevations of at least 4000 feet disclosed no significant differences from rates at lower elevations. Nevertheless, asthma mortality rates were significantly higher for blacks than whites at both high and low elevations. The asthma death rates per 100,000 general population for elevations less than 4000 feet were .160 for whites and .896 for blacks. Asthma death rates for elevations of at least 4000 feet were .209 for whites and 1.150 for blacks.
人们可能会认为哮喘的患病率会影响哮喘死亡率。在法国，海拔1350米处的哮喘患病率低于海平面处。对1980年美国海拔至少4000英尺的有人居住地区的县中5至34岁的黑人和白人的哮喘死亡率进行计算，结果显示与低海拔地区的死亡率没有显著差异。然而，在高海拔和低海拔地区，黑人的哮喘死亡率均显著高于白人。海拔低于4000英尺时，每10万普通人群中的哮喘死亡率，白人是0.160，黑人是0.896。海拔至少4000英尺时，白人的哮喘死亡率是0.209，黑人是1.150。
