Exercise may not be key to controlling weight  according to new research in Peer J.  Young adults from the United States and four other countries were studied by researchers who found that neight physical activity nor sedentary lifestyle were associated with weight gain. Researchers said that although exercis has many health benefits people who are physically active tend to be healthier but although this activity burns calories it also increases appetite, and people may compensate by eating more, or by being less active the rest of the day.

In the study participants in the 5 countries wore tracking devices called accelerometers on their waists for a week to measure their energy expenditure and step count. Researchers also measure their weight, height, and body fat. After the initial exam participants returned one and two years later. Initially only 44 percent of American men and 20 percent of American women met the U.S. Surgeon General physical activity guidelines that recommended at least two and a half hours of moderate-intensity aerobic exercise such as brisk walking weekly.

Results showed total weight gain was greater among those who met the physical activity guidelines. In America, men who met the guidelines gained a half pound per year, whereas American men who did not meet the guidelines lost 0.6 pounds. Researchers also found no relationship between sedentary lifestyle initially and subsequent weight gain or weight loss. The only significant factors for weight gain were weight at the initial visit, age and gender.

A new study published in Psycho-Oncology concluded that moderate to vigorous physical activity is related to improved subjective memory in breast cancer survivors. Researchers believe the exercise alleviates stress and benefits women psychologically, that in turn aids in memory. Researchers looked at memory and exercise in breast cancer survivors in two groups of 1,477 women and 362 women. Findings showed a link between improved memory with higher levels of physical activity in both groups of breast cancer survivors. They also found that increased physical activity had fewer subjective memory problems, a higher level of confidence. lower distress and fatigue that all influenced their subjective memory.

Are There More Deaths from Lack of Exercise or from Obesity?

A new study published in the American Journal of Clinical Nutrition concluded that twice as many deaths may be attributed to the lack of physical activity compared with the number of deaths attributed to obesity and a brisk 20 minute walk daily could reduce an individual’s risk of early death. . Physical inactivity has  consistently been associated with a great risk of heart disease, cancer and early death.,

In the sample of over 334,000 European men and women followed over twelve years researchers measured height, weight, and waist circumference, and used self-assessment to measure levels of physical activity. Findings showed that the greatest reduction in risk of premature death occurred in the comparison between inactive and moderately inactive groups based upon combining activities at work with recreational activities. Just under a quarter  (22.7%)of subjects were inactive based upon reporting of no recreational activity combined with a sedentary occupation. Researchers estimated that doing exercise equivalent to a 20 minute brisk walk daily would move an individual from the inactive to moderately inactive group and reduce their risk of premature death by between 16 and 30 percent. This was greatest among normal weight subjects but even those with a higher BMI saw benefits.

Using the most recent available death rates in Europe they estimated 337,000 of the 9.2 million deaths among Europeans were attributed to obesity (classed as a BMI greater than 30) but double this number of deaths (676,000) could be attributed to physical inactivity. Researchers said the message is that just a small amount of physical activity daily could have substantial health benefits.

CanPhysical Activity Influence Men Waking Up at Night to Urinate?

A new study published in Medicine & Science in Sports & Exercise concluded that men who are physically active are at lower risk of nocturia (waking up at night to urinate). Nocturia is a bothersome lower urinary tract symptom in men and increases with age. It may be related to an enlarged prostate, overproduction of urine, low bladder capacity and sleep disturbances.

Subjects in the study included 28,404 men who had BPH (enlarged prostate ) before enrolling in the study and 4,710 men (incidence group)  who had newly developed BPH. All men were between age 55 and 74 and all were asked about BPH related outcomes including enlarged prostate and PSA levels. nocturia, physical activity and other lifestyle factors.

Men in the incidence group who were physically active one or more hours a week were 13 percent less likely to report nocturia and 34 percent were less likely to report severe nocturiathan men who reported no physical activity. In this study nocturia was defined as waking two or more times a night to urinate and severe nocturia was defined as waking 3 or more times to urinate. Further studies are needed to study physical activity as a symptom management strategy.

A new study published in Cancer Epidemiology, Biomarkers & Prevention concluded that post menopausal women who undertook regular physical activity over the past 4 years that was equivalent to 4 hours of walking per week (cycling or other sports for 2 hours/week)  had a 10 percent lower risk for invasive breast cancer compared with women who exercised less during those four years.

Data was analyzed from over 59,300 post menopausal women in France. The me4an duration of follow up was 8.5 years during which time 2,155 women were diagnosed with a first primary invasive brteast cancer. The total amount of self-reported physaical activity per week was calculated and the reduction in invasive breast cancer among those having a higher amount of physical activity was independent of the body mass index, weight gain, waist circumference,  and the level of activity from 5 to 9 years earlier.

Lower Risk of Colon Cancer Death May be Related to Consistent Exercise Program

Friday, January 7th, 2011

In a new study reported in Cancer Edidemiology Biomarkers & Prevention researchers concluded that ” long-term participation in physical activity provides the greatest reduction in risk of colon cancer deaths.” Although previous research has shown an association between exercise and colon cancer risk, there has been little research on the effect of changes in physical activity and risk of colon cancer occurrence and deaths. Researchers examined the association of 10 year and 15 year change in physical activity with risk of colon cancer occurrence and death as part of the Cancer Prevention Study II. Deaths and Cancer Occurrence were verified through examination of medical records or the National Death Index linkage. Of the more than 125,000 individuals in the study there were 1863 Incident of colon cancer and 826 fatal cases (deaths) at the end of 10 years and 1386 incident and 602 fatal cancer cases at the end of 15 years. Findings showed that consistent high physical activity over the study period was associated with a decrease in colon cancer deaths compared to those who had a consistent low level of physical activity. “Those consistently at or above the sample median physical activity level over 15 years had half the risk of colon cancer deaths as those consistently below the median.” Neither measure of physical activity change was associated with the colon cancer incidence.

PreCancer Therapy Stress May Lead to Late Cancer Recurrence

Friday, October 8th, 2010

logo1267406_md

A study reported online in the journal Molecular Cancer Research concluded that patients experiencing physical or psychological stress including rigorous physical exercise a day or two before cancer treatment may activate a stress-sensitive protein that allows cancer cells to survive treatments including chemotherapy and radiation. This survival of cancer cells is related to the presence of heat shock factor-1 which has previously been linked to stress.

Carrying out a series of experiments using breast cancer cells the researchers found that a protein activated by the presence of heat shock factor-1 could block the process that kills cancer cells even after damage of cell DNA by radiation or chemotherapy. The heat shock factor-1 activated a specific protein (Hsp27) that helps the cancer cells survive. In all of their experiments the researchers saw that a heightened presence of Hsp27 protein was associated with a lowering of other proteins that facilitate cancer cell death. When they introduced siRNA, a molecule that assists in cancer cell destruction, the cell death mechanism was restored.
Although no drug currently exists the researchers believe that a drug with the same effect as the molecule siRNA, which is not suitable for patients, might stop the Hsp27 from preventing cancer cell deaths. More research in a clinical setting is needed to validate these findings.
