Difference in Bone Mineral Density between Young versus Midlife Women

American Journal of Health Education, v47 n3 p149-154 2016
Background: Older age is a risk factor for low bone mineral density (BMD). Older women have been found to have lower BMD than younger women. Recent trends for decreased calcium consumption and physical activity may place younger women at greater risk than previously anticipated. Purpose: The purpose of this study was to evaluate the effect of age on BMD in young (19.1 ± 0.4 years) versus midlife (46.3 ± 0.4 years) women. Methods: BMD was assessed with the Alara MetriScan. Results: Young women had lower BMD compared to midlife women (T score: - 1.18 ± 0.78 versus 0.25 ± 0.12; P < 0.05), lower body weight (65.6 ± 1.6 kg versus 79.6 ± 1.9 kg, P < 0.001), and lower body mass index (BMI; 23.7 ± 0.6 versus 29.3 ± 0.7 kg/m2, P < 0.001). Discussion: Based on these data, younger women are at greater risk for loss of BMD and early onset osteoporosis than their older counterparts. Translation to Health Education Practice: Health Educators should teach that calcium and vitamin D supplementations are vital in maintaining bone mineral density throughout an individual's life span.
