Relationship between bone mineral density, height Loss and lifestyle in adult women

Abstract

Introduction: Specific lifestyle characteristics of adult women can cause detrimental effects on bone mineral density. Objectives: Assessing the relationship between bone mineral density (BMD), loss height and lifestyle in adult women who attended to the Endocrine Foundation for Metabolic Diseases Research Applied and Clinical Research. Methodology: Cross-sectional and observational preliminary sample, non-probabilistic by convenience of 217 women over 40 years, who attended to FIEEM to perform bone densitometry to FIEEM. BMD (normal, osteopenia or osteoporosis) was analysed as dependent variable, determined by densitometry (Lunar Prodigy Advance team: software version 9.15, considering the score T-Score of measuring lumbar (L1-L4) as criteria WHO. Loss weight and lifestyle through weekly physical exercise, daily hours sitting and smoking, were analysed as independent variable. It was controlled for age, calcium intake and prescription drugs related to calcium metabolism. For statistical analysis, SPSS 15.0 was used, establishing measures of central tendency, X2 and logistic regression with Pearson correlation and Cramer's V, considering the value p <0.05. Results: Over 217 women (57.96.7 years), 47.9% have Osteopenia (-1.65±0.65) and 29.5% Osteoporosis (-4.77.±2.37). The loss height was 2.18±1.96 cm. The 77.9% of women made less than 3 times per week exercise, 22.5% stay more than 6 hours / day sitting and 19.4% of women smoked. By regression analysis it was observed statistical association between loss of BMD and age (r=0.175; p= 0.01) and number of hours per day sitting (r=0.314; p=0.000). At the same time, height loss was correlated with age (r = 0.176, P = 0.009) and smoking (r=0.184, p=0.006). Conclusions: In the sample analysed statistical association was found between BMD, age , number of hours sitting and smoking with loss od BMD and heith.
