Between 1988 and 1991, the relation between leisure time physical activity, bone mineral density (BMD), and osteoporotic fracture was evaluated in a cohort of community-dwelling California adults (1,014 women and 689 men) with a mean age of 73 years.
By means of a modified Paffenbarger questionnaire, participants were asked to report exercise from the past year and to recall their level of exercise during three other periods : the teenage years, age 30 years, and age 50 years.
The survey asked the number of times strenuous (e.g., jogging), moderate (e.g., fast walking), or mild (e.g., golfing) exercise was undertaken in an average week.
A summary score was constructed to represent lifetime exercise.
Analyses of the exercise-fracture and exercise-BMD associations were performed using logistic and linear regression analyses, respectively.
Linear regression models were controlled for age, body mass index, sex, diagnosis of arthritis, dietary calcium intake, and use of cigarettes, alcohol, thiazides, and estrogen (women only).
No association between current or former exercise and BMD at the radius, wrist, or spine was found.
A positive association between current exercise and BMD was found at the total hip (p=0.001) and at each hip component-greater trochanter (p=0.02), intertrochanter (p=0.001), and femoral neck (p=0.02).
