Background & Objective: Osteoporosis is a serious public health concern known to have several etiologic factors. This study compared lifestyles among postmenopausal women with normal and abnormal bone marrow densitometries (BMD).

Methods & Materials: In this case-control study, 81 postmenopausal women (33 cases with abnormal BMD and 48 control individuals with normal BMD) were selected using simple random sampling from Osteodensitometry center of Shariati hospital in Tehran. The BMD at lumbar spine and femoral neck had been measured with DXA. The Lifestyle was assessed using a questionnaire containing items about taking calcium, vitamin D, hormones, and Alendronat, doing physical activity, consuming tea and cola, and smoking. Reproductive characteristics were also collected via a questionnaire. Data were analyzed using χ2 test and independent sample t-test. Crude and adjusted odds ratios and relevant 95% confidence intervals were calculated through logistic regression, using SPSS v.13.

Results: The results showed significant differences between two groups in weight (P>0.001), BMI (P=0.022), number of pregnancies (P=0.002), number of children (P=0.004), duration of lactation (P=0.0002), dietary calcium intake (P≤0.001), and period of calcium supplement intake (P=0.002). The average of acquired scores of lifestyle factors in the case group was significantly lower than the control group (P=0.037). Inappropriate lifestyle had increased risk of the disease (OR=3.36, 95%, CI: 1.10-10.26). Meanwhile in the multivariate analysis, only insufficient intake of calcium was found to be a risk factor (P=0.002) for osteoporosis.

Conclusion: In conclusion, the results of this study showed positive effect of calcium intake on bone mineral density.

Background & Aim: Improving and modifying lifestyle is necessary for health maintenance and promotion. Modification of lifestyle can have an important role in the long-term health of women with Poly Cystic Ovarian Syndrome (PCOS). Therefore, this study aimed to determine the status of health promoting lifestyle and its socio-demographic predictors in women with PCOS.

Methods & Materials: This analytical descriptive cross-sectional study was conducted on 174 women with PCOS referred to gynecology and infertility clinics in Urmia-Iran, in 2015. The data were collected through the socio-demographic and Health Promoting Lifestyle Profile questionnaires. Descriptive statistics, independent t-test, one-way analysis of variance and multivariate linear regression were used to analyze the data through SPSS software version 21.

Results: The mean (standard deviation) of total score of the health promoting lifestyle was 2.2 (0.3) out of 4. The highest mean score was in nutrition subscale [2.9 (0.5)] and the lowest mean score was in the subscale of stress control [1.2 (0.5)]. Based on the multivariate linear regression model, the variables of BMI, spouse’s education level, the first supporter and menstrual bleeding amount were predictors of the health promoting lifestyle in women with PCOS.

Conclusion: Considering that the mean of total score of the health promoting lifestyle and some of its subscales were in the middle of the range of possible scores, it is necessary that besides other therapies, the improvement of health promoting lifestyle in women with PCOS, according to the influencing socio-demographic determinants, be on the agenda of health providers.
