Vegetarian Mothers Have More Girls

Updated 11:26 AM ET August 9, 2000

LONDON (Reuters) - A British study of how diet affects the health of new mothers and their babies
produced the surprise finding that vegetarian women are more likely to have girls, one of the report's
authors said on Tuesday.

In what is thought to be the first study of its kind, researchers at Nottingham University in central England
found significant differences in the sex of babies born to vegetarian and meat and fish-eating women.

"We were very surprised. It was just a fluke, this was something we were never looking to find," Pauline
Hudson, one of the report's authors, told Reuters.

"We were monitoring the health outcomes in vegetarian and non-vegetarian mothers, looking at things like
hemoglobin levels, which shows how much iron the mother has in her blood, and birth weights."

Hudson, a midwife teacher, and co-author Rosemary Buckley monitored the 5,942 pregnant women seen at
Nottingham's City Hospital during 1998, logging whether or not they were vegetarian -- defined as avoiding
meat and fish -- when they were booked in.

Nearly five percent were vegetarian, a total of more than 250 women.

"The birth ratio in Britain is that for every 106 boys born there are 100 girls, that's pretty constant," said
Hudson. "In our sample group of vegetarians there were 81.5 boys born for every 100 girls."

To further test their surprise findings -- and increase the sample number to what scientists call a "statistically
significant" level -- the pair extended their study for a further six months, looking just at the sex of babies.

The results, covering around 150 more vegetarian women, were "just about exactly the same".

The study also found that vegetarian mothers were less likely to smoke during pregnancy -- 10 percent did
so, compared with 20 percent of meat-eaters -- and more likely to breastfeed -- 80 percent against 60
percent.

These differences were attributed to the likelihood that a vegetarian and health-conscious lifestyle tend to go
together, and that some vegan mothers choose to avoid bottled milk containing dairy products.

Previous studies have shown that diets high in potassium, calcium and magnesium will produce more male
births, but there is no evidence that a vegetarian diet is low in these elements.

In an article outlining their findings in the British journal Practicing Midwife, Hudson and Buckley suggest
a further study could be carried out to investigate whether the diet of fathers affects the sex of their children.
