Abstract

Exercise training can improve blood pressure in normotensive, prehypertensive, and hypertensive subjects. One of the mechanisms of blood pressure reduction in hypertensive patients with obesity is through weight loss. This study aimed to examine the effect of exercise training on bodyweight and the relationship between weight loss and reduction of blood pressure. An experimental pre-post test design without controls was used to evaluate the effect of exercise training on weight loss. The study involved 89 elderly aged 50 years or more, consisting of 40 men and 49 women, who were members of Senayan Sport Fitness Club and had been exercising for at least three months. Exercise training was programmed and performed three times a week, consisting of aerobic (walking, jogging, static cycling), and resistance exercise. All exercise was performed for one to two hours with mild to moderate intensity. Blood pressure and body weight were obtained from medical records. Paired t-test showed that systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), pulse pressure (PP), and body mass index (BMI) were significantly lower after training [(systolic, 126.3 ± 2.9 vs 122.3 ± 2.7, p=0.02), (diastolic, 80.2 ± 3.1 vs 77.2 ± 2.4, p=0.00), (MAP, 95.6 ± 4.6 vs 92.2 ± 3.4, p=0.00), (PP, 46.1 ± 4.2 vs 45.1 ± 3.6, p=0.04), (BMI, 24.5 ± 2.9 vs 23.6 ± 2.9, p=0.04)]. Duration of training was the most influential factor affecting rBMI, (Beta = 0.38; p=0.00). Exercise training could lower BMI and the reduction in diastolic blood pressure was higher for the subjects aged 70 years and over.

Abstract

BackgroundThe osteoporosis self-assessment tool (OST) is a simple screening tool to assess risk of osteoporosis and to select high risk women for dual-energy x-ray absorptiometry (DXA) examination. This study aimed to evaluate OST performance in detecting low bone mineral density (BMD) in menopausal women.MethodsA cross-sectional study involving 60 menopausal women aged 50-65 years. The OST score was calculated from: [weight (kg) – age (yr)] x 0.2. Subjects were classified by OST score into low risk (OST ³2) and high risk (OST< 2) groups. BMD was determined by DXA at 3 bone locations (L1-L4, femoral neck, and total hip). DXA T-scores were categorized into: normal BMD (T-score >-1) and low BMD (T-score £-1). Independent t-test was used to compare subject characteristics between OST groups. Diagnostic performance of OST was evaluated by measuring sensitivity, specificity, positive & negative predictive value (PPV, NPV), positive & negative likelihood ratio (PLR, NLR) and receiver-operating characteristic (ROC). Significance was set at p<0.05.ResultsSubject characteristics and BMD between groups were significantly different (p<0.05). Most subjects (44/73.3%) had high risk of low BMD (OST < 2). Low BMD (T score £-1) was found in 43 subjects (71.7%) at L1-L4, 41 subjects (68.3%) at femoral neck, and 37 subjects (61.7%) at total hip. Diagnostic performance of OST was significant at total hip BMD (sensitivity=0.946, AUC=0.777).Conclusion We conclude that use of the OST score in menopausal women is effective and has adequate sensitivity and specificity. The highest diagnostic performance of OST is on total hip BMD.
