Background: There have been many studies on osteoporosis, which is one of the most important cause of fracture in adults. However, whether moderate physical activity during youth confers lasting benefits for bone is unclear. Thus, we are here concerned with the relation of teenage physical activity and bone mineral density in Korean premenopausal women. Methods: From March to June 2007, 75 clients who visited a general hospital for medical check-up were enrolled in this study. The subjects reported physical activity for four age periods (12∼18, 19∼34, 35∼49, current) using self reporting questionnaire. And they completed two 3-day food records, had measurements of height and weight, and aBMD assessed using dual-energy X-ray absorptiometry at the lumbar spine (L2-4) and femoral neck. Results: There was a significant relation of teenage physical activity (especially weight bearing physical activity) and aBMD in both sites (lumbar spine r=0.42, P＜ 0.01; femoral neck r=0.33, P＜0.01). But the activity during other age periods was not associated with the current aBMD at both sites. Conclusion: Our results suggest that moderate physical activity during the teen years appears to have lasting benefits for lumbar spine and femoral neck aBMD in Korean premenopausal women.

Background: There is an increasing interest in physical activity as a preventive and/or therapeutic option of non alcoholic fatty liver disease (NAFLD). The aim of this study was to examine the association between physical activity and ultrasound-diagnosed NAFLD. Methods: From April to June 2007, 198 clients who had consumed alcohol less than 140 gram per week among 598 clients who visited a general hospital for medical check-up were enrolled in this study. Clinical, biochemical variables and physical activity were compared. Physical activity was measured by self-reported questionnaire using IPAQ-short form in Korean version. Multiple logistic regression analysis was used to identify independent association. Results: The prevalence of NAFLD was significantly lower in the physical active group (more than 1500 MET- minutes per week) compared to the inactive group (9.6% vs 19.2%, P＜0.05). This association was not attenuated when adjusted for age, BMI, HDL cholesterol, triglycerides, fasting glucose, and HOMA2-IR (Odds Ratio 0.23 [95% CI 0.07∼0.77, P＜0.05]). Conclusion: Compared to the physically inactive group, the risk of NAFLD was lower in the physically active group. Our data suggests that regular and moderate physical exercise can prevent the development of fatty liver disease. (J Korean Acad Fam Med 2008;29:513-519)
Background
: The burden of cardiac complications during endoscopy are growing due to increasing proportion of elderly in the endoscopy target population. This study was conducted to examine the blood pressure changes before and after the endoscopy and to seek better pre-treatments in minimizing cardiac complications. Methods : One hundred subjects were chosen by consecutive sampling who visited a general hospital for physical examination. Basal, pre-endoscopic, immediate post-endoscopic blood pressure and blood pressure after 10 and 30 minutes were measured utilizing manual BP cuffs and recorded. Results : The subjects included 34 hypertensive patients. Twelve subjects were on anti hypertensive medication. In 5 consecutive measurements, significant variations on blood pressure was noted (P＜0.01). Blood pressure kept increasing until immediately after the procedure, followed by a gradual reduction. These changes were observed in both the normotensive and the hypertensive group, but the degree of changes were more pronounced in the hypertrensive group than the normotensive group (P＜0.01). The difference between basal and after procedure was 17.6 mmHg for systolic, 13.5 mmHg for diastolic in the normotensive group. However in the hypertensive group, the difference was 21.4 mmHg for systolic, 14.8 mmHg for diastolic. In comparison of medicated and non-medicated group in the hypertensive patients, the degree of changes were marginally, but significantly lower in the treatment group than in the non-treatment group (systolic P=0.056, diastolic P=0.049). Conclusion : The stress during endoscopy resulted in blood pressure changes, and the degree of changes was higher in the hypertensive group than the normotensive group. In the hypertensive group, the degree of changes was lower in patients treated with anti hypertensives than the non-treated patients. This sample size, however, was small.
