A new study reveals an association between prenatal exposure to environmental pollutants and elevated body mass index (BMI) during the first three years of life, as reported in Environmental Health Perspectives. The study also found associations between exposures to various pollutants and birth weight and length.

A new study reveals an association between prenatal exposure to environmental pollutants and elevated body mass index (BMI) during the first three years of life, as reported in the January 2009 issue of the peer-reviewed journal Environmental Health Perspectives (EHP). The study also found associations between exposures to various pollutants and birth weight and length.

Recent reviews support the hypothesis that even brief exposures early in life to endocrine-disrupting chemicals like pesticides, dichlorodiphenyldichloroethylene (DDE), hexachlorobenzene, dioxin-like compounds and polychlorinated biphenyls (PCBs) may increase body weight. Higher PCB levels were associated with higher BMI standard deviation scores (SDS) in children between ages 1 and 3. Higher DDE levels showed a slight increase in BMI SDS in 3-year-old children, with a somewhat stronger association in children of smoking mothers than of nonsmoking mothers. The study concluded that simultaneous intrauterine exposure to endocrine disruptors may compound the weight-enhancing effects of maternal smoking during pregnancy.

A random sample of 138 mother-infant pairs living in Flanders, Belgium was used for the study, with follow-up until the children were 3 years old. The study measured BMI as SDS of children ages 1 to 3, as well as pollutants measured in cord blood.

“There is a known correla¬tion between BMI during the preschool years and adult BMI,” wrote lead study author Stijn L. Verhulst and colleagues. “This is the first study demonstrat¬ing that environmental pollution may influ¬ence BMI during the critical first few years of life.”

EHP editor-in-chief Hugh A. Tilson, PhD said, “With childhood obesity continuing to increase at an alarming rate, this study is an important step in assessing possible mechanisms by which pollutants may alter energy metabolism early in life.”

Authors include Stijn L. Verhulst, Vera Nelen, Elly Den Hond, Gudrun Koppen, Caroline Beunckens, Carl Vael, Greet Schoeters and Kristine Desager.

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

TheStreet (July 21, 2014) — New research shows Gilead Science's drug Sovaldi helps in curing hepatitis C in those who suffer from HIV. In a medical study, the combination of Gilead's Hep C drug with anti-viral drug Ribavirin cured 76% of HIV-positive patients suffering from the most common hepatitis C strain. Hepatitis C and related complications have been a top cause of death in HIV-positive patients. Typical medication used to treat the disease, including interferon proteins, tended to react badly with HIV drugs. However, Sovaldi's %1,000-a-pill price tag could limit the number of patients able to access the treatment. TheStreet's Keris Lahiff reports from New York. Video provided by TheStreet
