Black men are now more likely to die from heart attacks, stroke and cancer than white males, according to a new study.

The study found that white men are four times more likely than black men to die of heart attack, stroke or cancer.

It also found that black men were four times as likely to get the most severe forms of cancer than the rest of the population.

Black men are twice as likely as whites to die before reaching retirement age.

Nearly half of black men have been diagnosed with prostate cancer, compared to 23 per cent of white men, according the study.

The researchers also found nearly half of the black men who have prostate cancer had at least one other type of cancer, which can be deadly.

A study last year also found black men in the US were three times more at risk of death than whites, according a new CDC report.

One in five men in America are living in poverty, the report said.

More than a third of black Americans aged 25-64 had been diagnosed as having hypertension in the previous 12 months, compared with 12 per cent in white Americans.

And the researchers found more than one in four black men with Type 2 diabetes, compared in age and sex with white men.

Experts said the findings highlight the need for greater community-based and family support services, and for more research on how race affects health.
