A new study has found that kids' books featuring animals with human characteristics not only lead to less factual learning but also influence children's reasoning about animals. Researchers also found that young readers are more likely to attribute human behaviors and emotions to animals when exposed to books with anthropomorphized animals than books depicting animals realistically.

Excess weight at one year postpartum increases moms' risk for diabetes, heart problems

Posted: 25 Mar 2014 07:26 AM PDT

Watch out for weight gain within a year of giving birth, to prevent new risk of diabetes and cardiovascular disease, experts say. While it has long been believed that not losing 'baby weight' for several years after pregnancy carries long-term risks of diabetes and heart disease, this research team aimed to test this theory by tracking risk factors and weight in the first 12 months after giving birth.

Posted: 25 Mar 2014 07:02 AM PDT

Young children who sleep less eat more, which can lead to obesity and related health problems later in life, reports a new study. The study found that 16 month-old children who slept for less than 10 hours each day consumed on average 105kcal more per day than children who slept for more than 13 hours. This is an increase of around 10% from 982kcal to 1087kcal.

Health-care professionals should prescribe sleep to prevent, treat metabolic disorders, experts argue

Posted: 24 Mar 2014 05:05 PM PDT

Evidence increasingly suggests that insufficient or disturbed sleep is associated with metabolic disorders such as type 2 diabetes and obesity, and addressing poor quality sleep should be a target for the prevention -- and even treatment -- of these disorders. Addressing some types of sleep disturbance -- such as sleep apnea -- may have a directly beneficial effect on patients' metabolic health, say the authors. But a far more common problem is people simply not getting enough sleep, particularly due to the increased use of devices such as tablets and portable gaming devices.

Women who have trouble getting pregnant may be under too much stress, according to a new study. According to researchers, women who had the highest levels of stress actually took 29 percent longer to get pregnant compared to other women, and their risk of infertility doubled. Researchers tracked 501 American women ages 18 to 40 years who were free from known fertility problems and had just started trying to conceive, and followed them for 12 months or until they became pregnant.

Overweight or obese teenagers who eat lots of salty foods show signs of faster cell aging, research indicates. Lowering sodium intake may be an easier first step than losing weight for overweight young people who want to lower their risk of heart disease.

Virtual conferencing effective weight management intervention

Posted: 20 Mar 2014 02:33 PM PDT

People participating in a virtual evidence-based group weight management intervention lost more weight than those in a control group. "This is a first attempt to deliver group-based healthcare services remotely, in a face-to-face virtual environment," said one of the study's authors. "In each intervention, eight participants attended meetings from their homes or offices, or any location of their choosing. Participants even joined the weekly meetings from different states in the United States and different countries while on business trips and vacation."

Face it: Instagram pictures with faces are more popular

Posted: 20 Mar 2014 10:47 AM PDT

Instagram pictures with human faces are 38 percent more likely to receive "likes" than photos with no faces. They're also 32 percent more likely to attract comments, research shows. The researchers also found that the number of faces in the photo, their age or gender didn't make a difference. On average, pictures of kids or teens aren't any more popular than those of adults, even though Instagram is most popular among younger people.

Posted: 20 Mar 2014 10:47 AM PDT

Obese women may need a different dose of medication than normal weight women in order to successfully have their eggs harvested for in vitro fertilization (IVF), according to a new study. IVF is a type of assisted reproductive technology used to help women become pregnant. More than 1 percent of all infants born in the United States each year are conceived using assisted reproductive technology.
