“…that have the highest prevalence of vertebral deformity, (23)(24)(25) consistent with the effect of trauma. The data on walking are also consistent with a number of previous studies that bone density is better preserved in those who exercise more; these have shown a positive correlation between time spent walking and lumbar spine bone density in middle aged women (26,27) and that when postmenopausal women exercise, BMD can increase in both unselected (28) and osteoporotic women. (29) There are a number of methodological issues to be considered.…”

Physical activity is associated with an increased bone mass and a reduced risk of hip fracture. There are, however, no data from population samples of men and women concerning the effect of regular levels of physical activity on the risk of vertebral deformity. The aim of this study was to determine the relationship between regular physical activity and vertebral deformity in European men and women. A population survey method was used. Thirty-six centers from 19 European countries participated. Each center recruited a population sample of men and women aged 50 years and over. Those who took part received an interviewer-administered questionnaire and lateral thoracolumbar radiographs. Subjects were asked about two dimensions of physical activity: (1) the level of physical activity undertaken either at work or at home on a daily basis at three different age periods: 15-25 years, 25-50 years, and 50؉ years; and (2) the amount of time spent walking or cycling out of doors each day. Spinal radiographs were evaluated morphometrically and the presence of vertebral deformity was defined according to the McCloskey method. In total, 14,261 subjects, aged 50 -79 years, from 30 centers were studied, of whom 809 (12.0%) men and 884 (11.7%) women had one or more deformities. After adjusting for age, center, smoking, and body mass index, very heavy levels of activity in all three age groups were associated with an increased risk of vertebral deformity in men (odds ratios, age adjusted [OR], 1.5-1.7; with all 95% confidence intervals [CI] excluding unity). No increased risk was observed in women. Current walking or cycling more than 1 ⁄2 h/day was associated with a reduced risk of vertebral deformity in women (OR 0.8; 95% CI 0.7-1.0). We conclude that regular walking in middle-aged and elderly women is associated with a reduced risk of vertebral deformity. By contrast, heavy levels of physical activity in early and middle adult life are associated with an increased risk in men. These differences are of relevance in understanding the epidemiology of vertebral deformity and planning programs of prevention. (J Bone Miner Res 1997;12:813-819)

“…This also has been observed in other studies, but caution again has to be expressed on a cross-sectional study where the occurrence of multiple deformities reduces physical activity. (29,30) Only with a prospective study would these relationships be evaluated with confidence. This study has permitted an interpretation of the relative contribution of trauma and conventional risk factors for reduced bone mass to vertebral deformity.…”

Recent epidemiological studies suggest a similar overall prevalence of vertebral deformity in men to that in women, though the influence of increasing age on the prevalence of vertebral deformity is less marked in men. However, most affected men have only a single or two vertebral deformities, which may be unrelated to osteoporosis. The aim of this study was to examine the role of risk factors, previously demonstrated to be associated with vertebral osteoporosis in females, in men with single/dual deformities compared to those with multiple deformities. Age stratified random samples of men aged 50 years and over were recruited from population registers in 30 European centers as part of the European Vertebral Osteoporosis Study (EVOS). Subjects had a lateral spinal radiograph and the presence of vertebral deformity was determined using the McCloskey algorithm. Lifestyle and other risk factor data were obtained from an interviewer-administered questionnaire. In all 6937 men with a mean age of 64.4 (SD ‫؍‬ 8.5) years were studied of whom 738 (10.6%) subjects had one or two deformities, and 109 (1.6%) subjects had three or more deformities. There was a marked increase in the prevalence of multiple vertebral deformities with increasing age, but only a modest effect of age on the prevalence of single deformities. Associations between various risk factors for osteoporosis and vertebral deformity were analyzed separately in men with single/dual vertebral deformity from those with three or more deformities using logistic regression. After adjustment for age, there were statistically significant associations between the following risk factors and multiple deformities: previous hip fracture (odds ratio [OR] 10.5), lack of regular physical activity (OR 2.9), low body mass (OR 2.5), and previous steroid use (OR 2.3). By contrast, there were only weak associations with these same variables in males with single/dual deformities and, apart from poor self-reported general health, all of the 95% confidence intervals spanned unity. There was no difference in the reporting of very heavy levels of physical activity under the age of 50 years between men with single/dual deformities and those with multiple deformities. In conclusion, men with multiple deformities showed a similar pattern of risk factor association to those seen in women with vertebral deformity, in contrast to men with single/dual deformities.

“…This kind of physical exercise exerts strain not only on the musculature of the lower extremities, but also on parts of the skeletal system, predominantly the lower limbs, the pelvis, and the spine [13]. Runners are particularly prone to stress fractures of the lower extremities [14].…”
