According to a new report in the British Journal of Psychiatry, babies born in springtime are more likely to develop anorexia nervosa, the BBC reports. Meanwhile, those born in autumn are at lowest risk. Temperature, sunlight, infection, or the mother’s diet could all be responsible, experts suggest, although others have countered that the effect was small and the disorder has many causes. The study involved analyzing data from previous studies that included 1,293 people with anorexia. They found more cases than expected occurred between March and June: for every seven cases expected, eight occurred. And there were fewer cases than expected in September and October.
