A recent report published in the American Journal of Clinical Nutrition, studies whether B-vitamin sufficiency in pregnant women protects against adverse effects of exposure to insecticide DDT on clinical pregnancy (CP) and sub-clinical early pregnancy loss (EPL).
The study was conducted by a group of researchers from the American society for nutrition. The researchers measured preconception concentrations of plasma B vitamins and serum total DDT in 291 women from Anhui, China, who were studied in 1996-1998. The women were followed prospectively from the time they stopped contraception until 2 months after CP (gestational age ≥42 d).
According to the scientists, the EPL was identified by using daily urinary human chorionic gonadotropin. The women were categorized according to B-vitamin status (deficiency compared with sufficiency) and DDT concentration (high compared with low).
