At the Children's Television Conference in 1996, President Bill Clinton underscored America's obsession with television when he noted that "a typical child watches 25,000 hours of television before his or her 18th birthday. Preschoolers watch 28 hours of television a week." If you tend to shrug off this fascination with the tube as harmless, consider a recent study in the Journal of the American Medical Association that examined the potential connection between TV viewing and obesity.
Nearly 200 third and fourth-grade students from two public elementary schools participated in the study, in which children from one school received an 18-lesson, six-month classroom curriculum to reduce television, videotape and video game use. The intervention was based solely upon teaching the children to budget their entertainment time and did not include other lifestyle modifications such as exercise. The second school received no curriculum to modify TV viewing and was compared with the initial group after six months.
Children from the first school showed significant decreases in body-mass index, triceps skinfold thickness, waist circumference and waist-to-hip ratio following the six-month educational program, especially compared to the second school that received no intervention to decrease TV viewing. Children from the first school also reported significant decreases in overall television viewing and meals eaten in front of the television.
These findings add to considerable evidence suggesting that television can influence our children, and the news isn't good. As parents, let's take the opportunity to do something about it. It's time to stop watching our children get fat.

Many doctors advise their patients to restrict work activities in an attempt to get them back to full working capacity faster. However, this practice may not be effective, say researchers.
A new analysis pooled data on employees at a utility company who had back pain-related absence. When researchers compared the 43% of subjects who were given work restrictions with those who were not, they found no statistically significant evidence that work restrictions effect duration of absence or likelihood of relapse.
“No evidence of an association between a prescription of work restriction and early return to work was found,” conclude the study’s authors. “More research is needed to clarify the utility of restricted duty in promoting a positive outcome for work-related low-back pain.”

If you're overweight and suffering from back pain, your doctor will probably suggest that you drop the extra pounds. Losing the weight is probably a good suggestion from an overall health perspective, but it might not be the answer to your back pain, at least not according to a recent study.
The potential association between excess weight and back pain was examined in 152 patients attending a hospital-based spinal pain unit. Researchers determined the body mass index (BMI) of each patient after measuring weight and height. (The BMI is essentially a scale that determines "appropriate" weight range by comparing weight and height.) Results showed that BMI had no significant effect on the incidence of back pain, except perhaps in cases involving extremely obese individuals.
If you're looking to lose some weight, exercise and dietary adjustments are a good place to start. But if you're suffering from back pain, the chiropractic office is the place to go. In fact, your doctor of chiropractic will be able to manage your back pain and also help you design a sensible program to shed those unwanted pounds.

Speaking of spines, a study published in a journal by the same name investigated whether atherosclerotic lesions in the abdominal aorta were more advanced in patients with low back pain (LBP) vs. those without pain. From 1991-1993, 29 patients (21-58 years of age) were evaluated with a diagnostic procedure called CT discography.
Results showed that 55% of LBP patients had atherosclerotic damage visible on CT scan, compared with only 21% of patients without LBP. This difference was further emphasized when examining a specific group of patients (50 years of age or younger): 48% of LBP patients had aortic damage vs. only 8% of patients without low back pain.
Atherosclerosis is so common that many people assume it's a normal consequence of aging, but don't be fooled: overwhelming research suggests that diet and lifestyle can play a major role in preventing this disease. Your chiropractor can provide you with more information on low back pain, atherosclerosis, and how you can avoid both.

The results of a study involving 12,986 men and women (45-64 years old at baseline) provide evidence that anger may predict coronary heart disease (CHD). As part of the Atherosclerosis Risk in Communities study, participants completed a trait anger scale assessing relative anger/rage; clinical examinations at baseline and follow-up assessed the incidence CHD and associated heart conditions.
High levels of anger contributed to an increased risk of CHD and other coronary events, including acute myocardial infarction (MI) and fatal CHD. Specifically, the investigators noted a three times greater risk for people with the greatest difficulty controlling their anger compared to those with the least difficulty.
The moral to this story: We all get frustrated and angry sometimes, but how we release or "control" our anger can make a big difference. It might mean the difference in staying healthy instead of suffering from heart disease. For more information, talk to your doctor.

What is the flu? Influenza is a respiratory infection that produces fever, chills, sore throat, muscle aches, and cough that lasts a week or more. The flu can be deadly for the elderly and those with compromised immune systems or who are suffering from diabetes, kidney dysfunction and heart disease. Each year about 20,000 Americans, mostly in these high risk groups, reportedly die from flu complications such as pneumonia.

As part of the analysis, investigators monitored the blood pressures and stress responses of 60 hypertensive adults who were caring for brain-injured spouses. Half of the subjects adopted dogs. After six months, dog-owners exhibited significantly lower blood pressure rises in response to stress, compared with those who did not own dogs.

Hostility (and anger) do little to contribute to health and wellness, but increasing evidence suggests that the opposite mechanism may take effect. Case in point comes from a study in the May 17, 2000 issue of the Journal of the American Medical Association. Hostility questionnaires administered to 374 men and women (18-30 years old at baseline) provided data on hostility (over a five-year period), and CT scans taken at year 10 examinations assessed the presence of detectable coronary artery calcification - heart disease.
Subjects with above-average hostility scores had more than two times the risk of coronary artery damage compared to less hostile subjects, and five-year changes in hostility were also related with incidence of the disease. The authors conclude that "a high hostility level may predispose young adults to coronary artery calcification."
So don't get mad, get healthy! Your doctor can tell you more about the risk factors for heart disease and help you maintain a healthy lifestyle.
