By Lisa Rapaport (Reuters Health) – Obsessive-compulsive disorder that surfaces during adolescence or early adulthood may actually have origins in the circumstances surrounding pregnancy and infancy, a Swedish study suggests. Smoking during pregnancy, cesarean section delivery, preterm birth, unusually low or high weight at birth and breech presentation at labor were all associated with an increased risk of obsessive-compulsive disorder (OCD) later in life, the study found. “Children who were born prematurely and to mothers who experienced serious problems with labor and delivery were at increased risk to develop OCD many, many years later,” Dr. James Leckman, author of an accompanying editorial, said by email.

By Stephanie Nebehay GENEVA (Reuters) – The World Health Organization said on Tuesday governments should raise taxes on sugary drinks to fight what it says are global obesity and diabetes epidemics.

Obesity more than doubled worldwide between 1980 and 2014, with 11 percent of men and 15 percent of women classified as obese – more than 500 million people, the WHO said.
