...Stress is thought to have a significant impact on the ability of the locus coeruleus to regulate noradrenaline properly, and Mehler and Purpura cite an improbable 2008 study published in the Journal of Autism and Developmental Disorders showing that mothers who lived through a hurricane during their pregnancy - particularly at the mid-gestational point - had a greater likelihood of giving birth to an autistic child than other women. "What would be involved here would be the mother's level of [the stress hormone] cortisol," says Purpura. "Between fetus and mother, the placenta acts as a very good barrier for maternal...
...stress chemistry could alter the development of the fetal locus coeruleus, though Purpura is quick to point out that the study showing how cortisol can make it through the placenta was conducted in animals, not humans. Nonetheless, one day after their article in Brain Research Reviews was published, the journal Psychoneuroendocrinology published a study linking cortisol imbalance to Asperger's syndrome, a condition along the autism spectrum...
Being a teenager means experimenting with foolish things like dyeing your hair purple or candy flipping or going door-to-door for a political party. Parents tend to overlook seemingly mild, earnest teen pursuits like joining the Sierra Club, but a new study in the Journal of the American Dietetic Association suggests that another common teen fad, vegetarianism, isn't always healthy. Instead, it seems that a significant number of kids experiment with a vegetarian diet as a way to mask an eating disorder, since it's a socially acceptable way to avoid eating many foods and one that parents...
...thing, many young "vegetarians" continue to eat the white meat of defenseless chickens (25% in the current study) as well as the flesh of those adorable animals known as fish (46%), even when they are butchered and served up raw as sushi. And in a 2001 study in the Journal of Adolescent Health, researchers found that the most common reason teens gave for vegetarianism was to lose weight or keep from gaining it. Adolescent vegetarians are far more likely than other teens to diet or to use extreme and unhealthy measures to control their weight, studies suggest. The reverse...
...revolutionary finding, but it represents some new thinking among researchers about how to tackle the burgeoning obesity epidemic, particularly among children. In the same journal, the first national survey of childhood obesity to include American-Indian and Asian ethnic groups found that 18% of 4-year-olds in the U.S. are obese, or in the 95th percentile of body-mass index (BMI), a ratio of weight to height. That percentage is almost doubled among American-Indian children, 31% of whom are obese...
