Medical research has documented a long list of health benefits linked to breast feeding. Now, the newest study finds mother's milk supply may be influenced by her weight. The Cornell Study published in the Journal Pediatrics, finds obesity affects the body's ability to produce a hormone that stimulates milk production and that in the first week after birth, overweight moms were lss likely to produce prolactin compared to the normal weight moms. Levels of the milk making hormone usually increase when a baby latches onto the breast, but researchers say that still didn't happen in their heavier moms. They say the findings may help explain why overweight women are less likely to breast feed.
New research is sending up another potential red flag about the effect of soda on our kids' health. But this time, the concern is not as much the calories as caffeine. The study funded by the National Institutes of Health found black teenagers who drank large amounts of caffeine had higher blood pressure than their peers. For some reasons the differences were not as obvious in the white teens. But researchers note that the potential connection should be studied further since hypertension among youngsters is on the rise.
The study involved 159 black and white 15 to 19-year-olds. All the kids ere allowed to choose from a menu of sodium controlled foods and beverages for a three day period. 90% of the caffeine kids consumed came from sodas, other sources included chocolate. Black kids who consumed 100 milligrams, about 4 twelve ounce sodas or more per day had systolic, top number blood pressure readings about 14 units higher than all kids who consumed fewer than 50 milligrams of soda per day. Several studies have shown a link between caffeine and blood pressure in adults. This research was conducted by scientists at the Medical College of Georgia. It was funded by the National Institutes of Health and is published in the Journal Archives of Adolescent and Pediatric Medicine.
Spanking has been the topic of a number of studies. Here's the latest. Researchers at Johns Hopkins School of Public Health followed nearly 2,000 children through their younger years and found that spanking under the age of two may be a risk factor for aggressive behavior later.
"Children who were spanked at least once in the previous week were approximately twice as likely as children who were not spanked to have behavior problems four years later that required their parents to come to school and discuss those problems with a teacher," explains Eric Slade from Johns Hopkins School of Public Health.
Researchers note they only studied white children, that further study will broaden to include other groups as well. But overall, they conclude that if spanking becomes part of a routine that keeps up as kids get older, Dr. Slade says it may be a red flag that there could be more serious issues involved and it's time for the family to get help.
