Bittles is the author of a new book that examines common misconceptions about cousin marriage. Durham, NC — The health risks of marrying a cousin have been grossly overstated, says a new book. A better understanding of the health effects of cousin marriage could mean more appropriate marriage laws and better medical care for cousin couples and their children. In ‘Consanguinity in Context,’ author and medical geneticist Alan H. Bittles of Murdoch University in Australia examines common misconceptions about cousin marriage from legal, cultural, religious and medical perspectives. Marriage between cousins is taboo in much of the Western world. In the United States, 31 of 50 states outlaw marriage between first cousins, or allow it only under certain circumstances.

Currently, the Act states marriage is “the union of a man and a woman to the exclusion of all others, voluntarily entered into for life”. The Federal Government announced this week that it would gauge public sentiment on same-sex marriage via a voluntary postal plebiscite.
The Act also states the minimum age for marriage is 18, though a judge may allow one partner to be 16 or older due to “exceptional circumstances”. Ms Schahinger said it was not unusual for removed cousins to learn of their common genetic link during the marriage process. Although common in centuries gone by, inter-family marriage creates enormous genetic stress, Professor David Thorburn of the Murdoch Children’s Research Institute said.
Professor Thorburn said this meant married relatives had a slightly lifted risk of having a child with a congenital or inherited disorder.

The risk of giving birth to babies with genetic defects as a result of marriages between first cousins is no greater than that run by women over 40 who become pregnant, according to two scientists who call for the taboo on first-cousin families to be lifted. Women in their forties are not made to feel guilty about having babies and the same should apply to cousins who want to marry, said Professor Diane Paul of the University of Massachusetts in Boston and Professor Hamish Spencer of the University of Otago in Dunedin, New Zealand.
Although first-cousin marriages are legal in Britain, there have been calls to ban the practice because of reports that it has resulted in a higher-than-average incidence of birth defects in certain immigrant communities where it is common and culturally acceptable.
As a matter of fact, if the example of Jacob, Rachel, and Leah is any indication, it would appear that cousin marriage was fairly common in the ancient world.
People lived to an average age of just 40 in 19th-century England, but that number is deceiving. Certainly, infants and children died of disease, malnutrition and mishaps at much higher rates than they do today. But if a girl managed to survive to adulthood, her chance of living to a ripe old age of 50, 60, 70 or even older was quite good. These odds only increased as the century progressed and improvements in sanitation, nutrition and medical care lengthened Victorian lifespans.
At the end of the 18th century, the average age of first marriage was 28 years old for men and 26 years old for women. Patterns varied depending on social and economic class, of course, with working-class women tending to marry slightly older than their aristocratic counterparts. But the prevailing modern idea that all English ladies wed before leaving their teenage years is well off the mark. Marrying your first cousin was perfectly acceptable in the early s, and the practice certainly offered some benefits: Wealth and property were more likely to remain in the same hands, and it was easier for young women to meet and be courted by bachelors within the family circle.
Later in the 19th century, though, marriage between cousins became less common. Meanwhile, the Victorian era saw a rise in awareness of birth defects associated with reproduction among relatives. Cousin marriages remained popular among the upper class, however. Charles Darwin married his first cousin Emma Wedgwood, for instance, and Queen Victoria and Prince Albert were themselves first cousins.
The popular image of young ladies lacing themselves into corsets drawn up as tight as their maids could make them is a bit misleading. While the Victorian era did feature fashions that emphasized a tiny waist only achievable through the careful application of whalebone and ribbon, most women wore their daily corsets with a healthy dose of moderation—not to the point of swooning on the divan.
We put our pants on one leg at a time like everyone else. And in six states, first-cousin marriages are allowed only under certain circumstances. In the case of Utah, marriages between first cousins are forbidden under most circumstances.
A cousin marriage is a marriage where the partners are cousins The practice was common in earlier times, and continues to be common in some societies today.
Subscriber Account active since. Through a combination of old prejudices and present-day conventional wisdom about inherited birth defects, first cousin marriage is seen by many as a little too close for comfort, as well as a bad idea if you want children. Further, if you include second cousins in the mix, according to the Clinical Genetics Handbook , the increased risks with regards to having children are nearly non-existent in this case compared with non-cousin marriage. While there have been instances of the banning of marriage between cousins at various points through history, such as the Roman Catholics banning the practice for a time starting with the Council of Agde in AD, for the most part marriage among cousins has been popular as long as people have been getting married.
Specifically, until the s or so, first cousins commonly married in Europe and the U. In fact, Charles Darwin, Mr. Natural Selection himself, was married to his first cousin Emma Wedgwood. Nonetheless, the practice soon fell out of fashion in the United States. Although never outlawed in England, during the second half of the 19 th century, many states began to ban marriages between first cousins, as part of a larger movement after the Civil War for greater state involvement in a variety of areas, including education, health and safety.
Researchers note that the distinction in marriage bans between England and the U. Regardless, cousin marriage bans began popping up across the states, with the first in Kansas The most recent state to ban cousin marriage was Texas in For your reference, this increase in birth defect rate is about the same as the increased risk of a woman having a baby when she is 40 vs.

But what are the actual genetic risks? In much of the world, consanguineous marriage between cousins is very common. For most Americans, however, marriage between cousins is at best a punchline, at worst a taboo. In many states, it is illegal for first cousins to get married. The objections are ostensibly based on the risk of genetic problems. But is there an actual risk?
Marriage between cousins were presumably more common. With the rise in the West of the Roman Catholic Church marriages between cousins.
An estimated 0. To assess consanguinity, researchers give relationships an inbreeding coefficient — the higher the number, the closer the two individuals are related. First cousins have an inbreeding coefficient of 0. Anything at or above 0. But the estimate that 0. For one thing, 25 states ban marriage between first cousins, and another seven states have restrictions on it for example, in Arizona first-cousin marriage is allowed only if both people are 65 or older, or if one is unable to reproduce.
Those laws might make some individuals reluctant to say they are in a consanguineous relationship and result in some undercounting of relationships. Bittles has spent almost 40 years researching consanguinity and has published more than papers on the topic. Bittles thinks that relationships between relatives may be on the rise in America because of immigration.
Immigration is relevant because consanguinity is much more common in some other countries. In fact, Bittles himself first became interested in the topic during a research trip to the Indian Institute of Science in Bangalore in Since then, Bittles has attempted to piece together a map on the global prevalence of consanguinity. His findings are summarized in the map below you can also view and download the numbers here.
Of the 70 countries studied, only 18 have consanguineous relationships as less than 1 percent of all marriages.
