How Much Is Enough?

1 Obese/Overweight People Exercise More Than Thought

Obese and overweight people exercise more than commonly thought, finds a new study that studied the activities and intentions of 175 overweight and obese people who answered questions about their exercise habits. Results indicate the following: 29% had been exercising for six months; 39% said they exercised regularly and 12% said they had no desire or thoughts of exercising. The Centers for Disease Control and Prevention says that 34% of the US population is obese, a condition that results in 300,000 deaths per year due to complications which include diabetes and cardiovascular disease. It’s notable that the study found that those with lower BMIs exercised more. Researchers hope to use results to help people move from contemplating exercising to actually doing it.

Stop Bottle at First Birthday

2 Prolonged Bottle Use May Increase Obesity Risk

Limiting prolonged bottle feeding could be an effective method of preventing obesity, suggest researchers from Temple University. Prolonged bottle users were defined as children who still used a bottle as their primary drink container at age 2, or were put to bed with a calorie-containing bottle. The researchers, publishing in Journal of Pediatrics, analyzed data from a large national study involving 6,750 kids born in 2001. They found that almost 23 percent of prolonged bottle users were obese by the age of 5.5 years. The obesity link remained even after researchers controlled for feeding practices during infancy, mother's weight and child's birth weight. Researcher Rachel Gooze notes that weaning from a bottle at age 1 is unlikely to be harmful and may be helpful in preventing obesity.

For Those at Risk

3 Drinking Coffee Increases Brain Aneurysm Risk

Coffee has had a bad reputation for being harmful to health, but recent studies have found positive benefits to consumption of a cup. Unfortunately, not the researchers at the University Medical Center in Utrecht, The Netherlands. They found coffee to be one of eight triggers that could temporarily raise one’s risk of rupturing an intracranial aneurysm (IA) – a weakness in the wall of a brain blood vessel that causes it to balloon and possibly rupture. An estimated 2 percent of the general population has an IA, but few rupture. Coffee consumption increase the risk by 10.6 percent, find the researchers. Other triggers include cola consumption, vigorous physical exercise, nose blowing, being angry or startled, and having sex. The risk is also slightly higher after consuming alcohol.

Is New Better Than Old?

4 New Drugs Lack Data Comparing Them to Older Drugs

A study done by Harvard Medical School in Boston analyzing 10 years of records regarding 197 U.S. FDA-approved drugs for diseases that already had treatments, found that about 30 percent of drugs approved did not have any information comparing them to current drugs for the same condition. Data eventually comes out but often years after the drug has been on the market. The FDA does not require that experimental drugs be compared to current medications, only to a sugar pill or placebo. This ultimately means it is unknown if the new drug works better than current ones and does not give doctors the ability to make a well-informed decision about whether or not to prescribe it. The fact that 70 percent of new drugs had comparison data was a shock to some researchers.
