Osteoporosis In Males Is Common

A new study from the University of Toronto/Ontario has shown that contrary to the conventional teaching ostoporosis is not only a problem in females, but also a problem in males. The Canadian Multicentre Osteoporosis Study (CaMos) showed according to the epidemiologist Natalia Diaz-Granados that in Canada 16% of all women above the age of 50 and 5% of men above the age of 50 developed osteoporosis.

In the past men were thought to be more or less immune to osteoporosis, but this is not so. The results of this study were presented recently at the annual meeting of the American Society for Bone and Mineral Research in Minneapolis. 1,768 of the 2,884 men who were recruited into CaMos were eligible for the study, because they had not taken oral corticosteroids for three months, and bone scans were taken to measure bone density of their upper femurs (upper thigh bones). 89 men (or 5% of the group of 1768) showed osteoporosis. The mean age of this group was 65 years ranging from 50 to 96.

The researchers studied the high risk factors in men with osteoporosis and found that they were remarkably similar to the risk factors in women with osteoporosis. I have summarized the findings here in tabular form.
The study also showed that for men hip fractures seem to be more lethal than for women as within a year after a hip fracture from osteoporosis more men die. If a physician sees a patient and notices 2 or more of the risk factors identified in the table above, a bone scan to screen for osteoporosis should be done.

There are many more unanswered questions with regard to life styles and nutritional information. It is not known from this study whether the men were physically less active and whether there was a higher alcohol abuse and /or nutritional dysbalance with associated vitamin deficiencies. The authors stated that future research will focus on these factors and on whether biphosphonates (alendronate or Fosamax) are as useful in men with osteoporosis as they are in women.

Risk factors for osteoporosis in men
Risk factor: Explanation:
weight less than normal this may point to poor nutrition, lack of calcium, vit. D etc.
older men bone loss occurs slowly with age, both in men and women
history of smoking smoking reduces blood supply to the nutritional vessels in the bone. This leads to less bone forming cells (osteoblasts)
family history of osteoporosis one or more genes code for osteoporosis. More research needed in this field to develop new medications
history of fracture beyond the age of 50 osteoporosis leads to brittle bones with more fractures. A fracture in this age group should make the physician suspicious of osteoporosis or a metabolic bone problem

Based on an article in The Medical Post, page 78, Oct. 14, 2003.

Exercise Saves Lives In Women Over 65

A recent study released in the Journal of the American Medical Association (JAMA Vol. 289 No. 18, May 14, 2003) has found a profound effect of exercise on the survivial of elderly women. Dr. Gregg et al. have followed 9518 women aged 65 or older for a total of 12.5 years with a follow-up visit in between at about the 6 year point. They found that women who exercised (walking, aerobics etc.) and who were compared with a control group who was sedentary (no form of exercise), had the following improved survival rates.

These findings were independent of other factors up to an age of 75 years. In other words, age, smoking, weight and a number of pre-existing diseases did not influence these improved survival figures from the effect of exercise. However, when a woman had a significant chronic disease or was older than 75 years of age, the survival improval from exercise was not as strong as indicated in the table above. Also, the follow-up visits showed that those women who exercised continually, had the highest survival advantage.

The bottom line: increasing and maintaining a physical exercise program will likely lead to a longer life. At the same time the exercise program needs to be started early enough to be of benefit to those who are older than 75 years of age.

Disease and death rate reduction from exercise in women aged 65 and over
Reduction of:
Effect of risk reduction:
overall death rates 48%
cardiovascular disease 36%
cancer 51%

Some of the Associations that were contributing to this important study were: The National Center for Chronic Disease Prevention and Health Promotion (Atlanta, Ga), the Graduate School of Public Health, University of Pittsburgh (Pittsburgh, Pa), the Prevention Sciences Group, Departments of Medicine and Epidemiology and Biostatistics, University of California (San Francisco) and the University of Minnesota and Section of General Internal Medicine, Veterans Affairs Medical Center, Minneapolis.

Framingham Study…Obesity And Smoking Lead To Loss Of Life

The Netherlands Epidemiology and Demography Compression of Morbidity Research Group has published an important medical research paper in the Jan. 7, 2003 edition of the Annals of Internal Medicine (Ann Intern Med 2003;138:24-32).

The lead researcher, Dr. Anna Peeters, explained that the group has revisited the Framingham Heart Study 40 years later and analyzed survival statistics of the group of men and women who enrolled in this longterm study between 1948 and 1951. The population at the beginning of the study was aged between 30 and 49. The snap shot, after 40 years had elapsed, is the subject of this analysis. In order to make it easier to understand, I have tabulated the data as seen below.

This study shows that life style choices do matter: being overweight shortens your life by 3 years on average, being obese shortens it by 6 to 7 years.

Add the risk of smoking, and you end up shortening your life by 7 years in the case of being overweight (4 years more than without smoking) or more than 13 years, if you are obese.

Framingham Study...Obesity And Smoking Lead To Loss Of Life

Framingham Study…Obesity And Smoking Lead To Loss Of Life

This study was based on 3,457 participants who 40 years ago had a life expectancy of 85 years, if they were in the normal weight category and did not smoke.

The death rates were much higher than the researchers expected. The researchers from the Erasmus Medical Center in Rotterdam stated as a conclusion: ” just think about two things: Don’t get fat and don’t smoke”.

Years of life lost 40 years after Framingham Heart Study Was Started:
Non-smokers: Smokers:
  Male Female   Male Female
overweight *: 3.1 3.3 overweight*: 6.7 7.2
obese** : 5.8 7.1 obese ** : 13.7 13.3
* overweight:BMI25 to 29.9 ** obese:BMI = 30 and higher

More Exercise Leads To More Health

Based on an article in the Journal of the American Medical Association (JAMA 2002;288:p.1994-2000) Dr. Mihaela Tanasescu and his group from Loma Linda University in California have followed more than 44,000 health care professionals every 2 years for 12 years.

He asked the question whether a difference could be found between light, moderate or heavy exercise in the prevention of heart attacks.

Here is what they found: 1700 new cases of heart attacks as a result from hardening of arteries were mostly found in those who did NOT exercise or were in the LIGHT aerobic category. The more the persons exercised, the more pronounced the heart protective effect was. For instance, the group of men who engaged in a heavy exercise program had developed 17% less heart disease than the group with the light exercise program. Contrary to the marathon runner studies that had reported a detrimental effect at the high end, this study did not find this effect.

Also, this study is one of the first to show that weight training and other muscle strengthening activities also reduced strokes and heart attacks. Up to now the medical community was of the opinion that body building type muscle training might not prevent strokes or heart attacks.

The authors concluded that a combination of aerobic exercises(brisk walking, running, sports etc.) with muscle strengthening exercises(body building, stretching exercises, weight lifting etc.) will give the most beneficial heart protecting health effect.
