Abstract

Osteoporosis in women is a growing public health problem that is associated with irreversible effects. With regard to the important role of reproductive factors on bone mineral density in women that this study will be done with the aim of determining the relationship between fertility factors and decreased bone density in women. Materials & Methods: In this descriptive - cross sectional study, 215 women above 30 who were free of diseases affecting bone density were selected using available sampling. The tool for collecting data was a two-part questionnaire with demographic information and a checklist of fertility factors. Bone density was calculated with DEXA technique using Hologic device in area L1-L4 and Femoral neck. Spss 17th Edition and statistical analysis tests were used for data analysis. Results: The findings showed that mean and SD of age, height, weight and BMI of samples, were respectively 54. 36±8 year. and 155.53± 6.30 cm and 72.05± 10.99 Kg and 29.88 ± 4.64 Kg / m 2.Among participants 163 (75.8%) were postmenopausaland 52 (24. 2%) were premenopausal. According to the regression model, among fertility factors studied, the number of delivery is the only predictor of femoral neck and lumbar spine T-score in postmenopausal women studied (p <0.05). Breastfeeding duration had a significant relationship with rate of positive changes in femoral neck in premenopausal women and duration of use of contraceptive pills with negative changes rates in both areas studied found in premenopausal women (p <0.05). Conclusion: Given the key role of reproductive factors on bone density in women, it is necessary to apply optimal measures and contrivance in reproductive ages in terms of calcium intake and other nutrients and lifestyle adjustments in order to prevent the burden some consequences of osteoporosis in nonreproductive ages by reducing the negative role of fertility factors.
