A report released this week by Centers for Disease Control and Prevention shows that lumberjacks, farmers and fishermen have among the highest suicide rates by occupation in the United States.

These three jobs coincide with each other in that they feature hard manual labor, frequent isolation and uncertain earnings, the study notes, according to the Associated Press.

Meanwhile, a second study released this week by JAMA Psychiatry — a journal of the American Medical Association — demonstrates that American women who go to church regularly have a “substantially lower suicide risk” than women who never attend church services.

The JAMA Psychiatry study, which involves nearly 90,000 nurses (mostly female ones) found that the suicide rate among Catholic and Protestant female nurses was nearly half the rate among all women nurses.

Among the 7,000 Catholic female nurses who said they attended mass more than one time each week, the suicide rate was zero percent. Exactly none of them committed suicide, according to the study, the Catholic League noted in a press release sent to The Daily Caller.

The JAMA Psychiatry study is a longitudinal one covering a very large group of nurses from 1996 to 2010.

The Centers for Disease Control study of suicide by occupation found that other male-dominated manual labor jobs — construction workers, carpenters, miners, electricians, factory workers and mechanics — also have high suicide rates.

Librarians, doctors and teachers have some of the lowest suicide rates, according to the CDC study, which logged the suicides of 40,000 Americans in 17 states in the year 2012.

While tragic suicides among teens and college students frequently garner media attention, middle-aged men actually kill themselves the most.

Females who commit suicide most frequently work as corrections officers, police officers and lawyers, the Associated Press notes.

Men overwhelmingly eclipse women in the phenomenon of suicide.

According to the CDC, suicide rates in the United States have spiked upward in the last two decade.

People who are affiliated with no religion have the highest suicide rates, according to the Catholic League.
