[ti:How Long Americans Live Depends on Where They Live] [by:www.21voa.com] [00:00.00]更多听力请访问21VOA.COM [00:00.12]A new study has found that how long Americans live [00:05.80]depends on where they live. [00:10.48]Researchers at the Institute for Health Metrics and Evaluation or IHME [00:18.84]at the University of Washington in Seattle found that the gap [00:24.28]between counties with the highest and lowest life expectancies [00:29.20]is larger now than it was in 1980. [00:33.64]And life expectancy is falling in some counties. [00:40.04]The researchers say this shows there is a large [00:43.84]"and growing inequality in the health of Americans." [00:48.92]Several counties in the states of North and South Dakota, [00:53.64]where many Native Americans live, have the lowest life expectancy rate. [01:00.12]In Oglala Lakota County, South Dakota, [01:04.83]the life expectancy was 66.8 in 2014. [01:10.24]There has also been a drop in the life expectancy rate [01:15.08]in counties in poor areas of Kentucky and West Virginia. [01:21.88]In Owsley County, Kentucky, life expectancy was 72.4 years in 1980. [01:30.88]But by 2014 it had fallen to 70.2. [01:36.47]Some of the counties with the highest life expectancy [01:41.04]are in the western state of Colorado. [01:44.36]Summit County had the longest life expectancy at 86.8 years. [01:51.20]It was 86.5 in Pitkin County and 85.9 in Eagle County. [02:00.04]The average life expectancy in the United States was 79.1 in 2014. [02:08.08]Dr. Ali Mokdad is one of the authors of the study. [02:13.12]He says the findings demonstrate an urgent need [02:17.60]"to reduce inequality in the health of Americans." [02:22.56]He says "federal, state and local health departments [02:26.51]need to invest in programs that work [02:29.24]and engage their communities in disease prevention and health promotion." [02:35.96]The study showed that spending more money on healthcare [02:40.26]does not appear to increase life expectancy. [02:44.68]The United States spends more per person on health care [02:48.32]than many developed countries -- $9,237 per person in 2014. [02:56.44]That compares to $4,032 spent by Australia, [03:03.20]which has a life expectancy of 82.3 and Japan, which spent $3,816 [03:13.68]and has one of the highest life expectancies in the world at 83.1. [03:21.80]Laura Dwyer-Lindgren is a researcher at IHME [03:26.16]and one of the authors of the study. [03:29.16]She says examining "life expectancy on a national level [03:33.56]masks the massive differences that exist at the local level, [03:39.16]especially in a country as diverse as the United States. [03:44.80]Risk factors like obesity, lack of exercise, high blood pressure, [03:50.92]and smoking explain a large portion of the variation in lifespans, [03:57.12]but so do socioeconomic factors like race, education and income." [04:04.68]Dr. Christopher Murray is the director of the IHME. [04:09.56]He says "the inequality in health in the United States [04:14.60]-- a country that spends more on health care than any other -- is unacceptable. [04:20.76]Every American, regardless of where they live or their background, [04:25.72]deserves to live a long and healthy life. [04:30.08]If we allow trends to continue as they are, [04:34.00]the gap will only widen between counties." [04:37.72]The study was published Monday in JAMA Internal Medicine.
