White Americans living longer with muscular dystrophy than African-Americans

A new study shows that white men and boys are living longer with muscular dystrophy due to technological advances in recent years, but that the lives of African-American men and boys with muscular dystrophy have not been extended at the same rate. Muscular dystrophy is a group of inherited muscle diseases that often lead to early death due to respiratory or heart failure.

The study also found that white women with muscular dystrophy live an average of 12 years longer than African-American women with the disease. For the study, researchers analyzed death records from 18, people whose death was associated with muscular dystrophy in the United States from through This period of time was when use of supportive medications and many advances in respiratory and heart care were developed and applied to those with muscular dystrophy.

The average age at death increased by 1. Among men who had no weakening of the heart associated with muscular dystrophy, called cardiomyopathy, the average age at death increased by 1. Nicte Mejia, MD, of Massachusetts General Hospital and a member of the American Academy of Neurology, who wrote an editorial accompanying the article, said, "Inequities in the health care delivery system -- and the multiple ways in which race constrains access to care -- seem the most likely explanation for this racial disparity.

Decades of research show that African-American patients have worse access to health care and inferior outcomes than white patients. This study reminds us that we must work to minimize social barriers and provide excellent care to all patients. Materials provided by American Academy of Neurology.

The history of a narrative by Antonio de Torquemada shows how in this process Africans became demonised and the demons racialised. The story seems to be apocryphal — no documentation has been found for it — but its widespread circulation testifies to the decolonial aspiration of muscular black people of Africans. After slavery ended, this interracial mixing dropped off steeply. The results also show that essentially all African Americans muscular black people some European ancestry ancestry as pepole. He characterised the region as a hotbed of monsters, arising from the sexual union of humans and animals.

Our genetic make-up is the result of history. This means that, to understand how genes affect our biology, geneticists often find it important to tease out how historical drivers of demographic change shaped present-day genetics. Understanding the connection between history and DNA is especially important for African Americans, because slavery and discrimination caused profound and relatively rapid demographic change. A new study now offers a very broad look at African-American genetic history and shows how the DNA of present-day African Americans reflects their troubled history. Slavery and its aftermath had a direct impact on two critical demographic factors that are especially important in genetics: migration and sex. The trans-Atlantic slave trade was a forced migration that carried nearly , Africans over to the colonies and, later, the United States.
