[00:15.64]The study showed that the number of suicides increased sharply after 2006. [00:23.80]Economic conditions in the U.S. began to worsen at that time. [00:30.64]A recession began in 2008. [00:35.00]The suicide rate increased for men under the age of 75 [00:40.92]by 43 percent between 1999 and 2014. [00:48.44]For women under the age of 75, [00:52.48]the greatest rate of increase was among those between 45 and 64. [01:00.08]The suicide rate among those women was 80 percent higher in 2014 than in 1999. [01:09.76]Men are much more likely to kill themselves than women. [01:16.32]However, the study showed the rate of women [01:20.52]who took their own lives grew much faster than among men. [01:27.48]The study found men are more likely than women to use a gun. [01:33.88]Fifty-five percent of men who killed themselves in 2014 used a gun. [01:40.88]Among women, 31 percent used a gun. [01:46.24]About 34 percent of women used poison. [01:51.04]Suffocation is more common now than it was in 1999, [01:58.20]when 20 percent of those who killed themselves used the method. [02:04.40]In 2014, the rate increased to 25 percent. [02:11.96]The suicide rate for non-Hispanic black men was lower in 2014 than in 1999. [02:21.76]Black men are the only ethnic group of either gender whose suicide rates decreased. [02:30.04]Experts say most people who try to kill themselves are not successful. [02:36.60]They say taking steps to try to convince someone not to kill themselves is important. [02:45.64]Researchers say removing the methods people use to kill themselves, [02:52.24]such as guns or poison, can help for a short period. [02:58.96]This can give long-term treatment time to take effect. [03:03.96]The CDC said the suicide rate is increasing [03:09.60]while the rate of all deaths is declining. [03:14.28]It said suicide is one of the top ten causes of death [03:19.28]in each age group from 10 to 64 years old. [03:25.48]I'm Christopher Jones-Cruise. [03:27.96]更多听力请访问51VOA.COM
