Kids who have a TV in their bedroom are at a significantly higher risk of obesity and a larger waist circumference.
This finding came from a study in American Journal of Preventive Medicine which showed that a child’s waist size may greatly increase with prolonged TV viewing. The research is similar to a prior report which indicated that children’s muscular fitness decreases the more hours they spend watching TV, while their waistline gets bigger.
Kids between the ages of 8 and 18 in the United States watch an estimated 4.5 hours of television each day, and a TV is found in the bedroom of 70% of these children.
Obesity affects one-third of adolescents aged 6 to 19. Previous research demonstrated that childhood obesity can be prevented by sitting down to a family dinner more frequently and reducing the amount of TV viewed.
Studies have also shown that the amount of television viewed as a child remains the same in adulthood, therefore, the person becomes overweight and ends up with high total cholesterol.
A team of researchers, from the Pennington Biomedical Research Center in Baton Rouge, LA, demonstrated the association between having and viewing television in the bedroom and obesity in children, particularly elevated waist circumference.
Peter T. Katzmarzyk, PhD, leading researcher, said:
“The established association between TV and obesity is predominantly based on BMI. The association between TV and fat mass, adiposity stored in specific depots (including abdominal subcutaneous and visceral adipose tissue), and cardiometabolic risk, is less well understood. It is hypothesized that higher levels of TV viewing and the presence of a TV in the bedroom are associated with depot-specific adiposity and cardiometabolic risk.”
There were 369 kids and teens aged 5 to 18 from Baton Rouge, Louisiana who were involved in the study between 2010 and 2011. There was a balance between BMI status, gender, age, and ethnicity among the subjects, who were assessed for:
- fat mass
- stomach fat
- waist circumference
- fasting triglycerides
- resting blood pressure
- high-density lipoprotein cholesterol
Analysis showed that when kids had a TV in the bedroom, they had a higher probability of viewing more television.
In contrast to the children who did not have a TV in their room, those with a bedroom TV had a higher waist circumference, more fat and more subcutaneous adipose tissue mass.
The subjects who had a bedroom TV and who also viewed over 2 hours of TV a day, were shown to have 2.5 times the odds of the highest levels of fat mass.
Watching television for over five hours doubled the likelihood of being in the top quartile for visceral adipose tissue mass.
A TV in the bedroom was linked to three times the odds of:
- high waist circumference
- high cardiometabolic risk
- elevated triglycerides
Amanda Staiano, PhD, co-author, concluded:
“There was a stronger association between having a TV in the bedroom versus TV viewing time, with the adiposity and health outcomes. A bedroom TV may create additional disruptions to healthy habits, above and beyond regular TV viewing. For instance, having a bedroom TV is related to lower amounts of sleep and lower prevalence of regular family meals, independent of total TV viewing time. Both short sleep duration and lack of regular family meals have been related to weight gain and obesity.”
SURGEONS once made incisions large enough to get to a gallbladder or other organs by using conventional tools they held in their own hands. Today, many sit at a computer console instead, guiding robotic arms that enter the patient’s body through small openings not much larger than keyholes.
Researchers looked at numerous heart (cardiac) risk factors before and after gastric bypass surgery and found all improved.
Improvements in heart risk factors included:
- Total cholesterol declined from 184 before surgery to 174 after. (Below 200 is recommended.)
- HDL or “good” cholesterol rose 40%.
- LDL or “bad” cholesterol improved.
- Triglycerides (blood fats) declined by about 55%.
Obesity is fuelling a major increase in the number of cases of kidney cancers diagnosed in Britain, experts say.
Obesity increases kidney cancer risk by about 70%, compared with smoking which increases it by about 50%.
The experts say that being overweight increases the risk of this cancer, as well as others including breast, bowel and womb cancer, because it causes the higher levels of certain hormones to be produced, compared with those seen in healthy people.

For the 90 million Americans impacted by obesity, bariatric surgery is becoming an increasingly popular option to jump start weight loss.
The procedures are life-saving in many instances, but not just because of the drastic weight loss. Doctors are quickly discovering that weight-loss surgeries can help improve symptoms associated with hypertension, diabetes and cardiovascular disease.
Researchers have identified two genetic variations that appear to increase the risk of childhood obesity.
The study authors took data from North American, Australian and European meta-analysis of 14 studies consisting of 5,530 obese children and 8,318 non-obese kids. The team compared the genetic data.

Two studies have found that weight-loss operations worked much better than the standard therapies for Type 2 diabetes in obese and overweight people whose blood sugar was out of control. Those who had surgery, which stapled the stomach and rerouted the small intestine, were much more likely to have a complete remission of diabetes, or to need less medicine, than people who were given the typical regimen of drugs, diet and exercise.
The surgery also helped many to lower their blood pressure and cholesterol.
A Manitoba man says his life has been transformed since he underwent a weight-loss surgical procedure that he paid for himself, as he did not qualify for a provincial pilot program.
Keith Doerksen of Morden, Man., says he has lost about 150 pounds since he underwent vertical sleeve gastrectomy in January 2011.

A clear association between obesity and pain — with higher rates of pain identified in the heaviest individuals — was found in a study of more than one million Americans published January 19 in the online edition of Obesity. In “Obesity and Pain Are Associated in the United States,” Stony Brook University researchers Arthur A. Stone, PhD., and Joan E. Broderick, Ph.D. report this finding based on their analysis of 1,010,762 respondents surveyed via telephone interview by the Gallop Organization between 2008 and 2010
.”We wanted to explore this relationship further by checking to see if it was due to painful diseases that cause reduced activity, which in turn causes increased weight,” says Joan E. Broderick, Ph.D., Associate Professor in the Department of Psychiatry and Behavioral Science and School of Public Health at Stony Brook University, and lead investigator of a National Institutes of Health-funded study on how arthritis patients manage their own pain.

“Economy Class Syndrome” is a myth, your risk of developing a blood clot during a long-distance economy trip by plane is not higher than in first class, researchers report in an article published in Chest. The American College of Chest Physicians (ACCP) has issued new evidence-based guidelines which address some of the risk factors linked to DVT (deep vein thrombosis) – it says that there is no compelling evidence linking economy class air travel to the development of DVT.
