Mosquito repellers made with pesticides were known to have increased the risk of miscarriage among pregnant women but a new study shows they remain protected if they have adequate levels of Vitamin B.
Women with B vitamin adequacy are more likely to get and stay pregnant despite high levels of DDT that is detrimental to reproductivity, said researchers from Johns Hopkins Bloomberg School of Public Health.
“Our previous work has shown that high levels of DDT in the body can increase the risk of early miscarriage,” said study lead author Xiaobin Wang. “We have shown that women with high levels of DDT who also had high levels of B vitamins had a better chance of getting and staying pregnant than those were deficient in those vitamins,” Wang said.
Since DDT remains in the body and environment for decades, the researchers conducted their survey on a group of female Chinese textile workers who were trying to get pregnant. Those with high DDT levels and sufficient levels of vitamin B were found to have had a 42 percent greater chance of early miscarriage than women with lower DDT levels.
But in those with high DDT levels and vitamin B deficiencies, women were twice as likely to suffer a miscarriage before six weeks of pregnancy. The researchers also found that women with high DDT and low B vitamin levels took nearly twice as much time to conceive in the first place.
Vitamin B is available in leafy green vegetables, fish, poultry, meat, eggs and dairy products, among other food items. The study was published in the American Journal of Clinical Nutrition.
