The objective of the study was to identify the factors that are associated with bone mineral density in women. We evaluated 609 women between 35 and 60 y, 45% living in the city of Queretaro, Mexico and 55% living in rural communities. Bone mineral density (BMD) and body composition were measured with DEXA, and a fasting blood sample was taken to measure glucose and lipids profile. Anthropometry measurements included weight, height, waist and hip circumference. In a linear regression analysis age was associated negatively with BMD (95% CI: −0.0058, −0.0035 g/cm 2 ). After controlling for age, a linear regression analysis showed a direct association of DMO with cholesterol (95% CI: 0.0000, 0.0003 g/cm 2 ), fat free mass (95% CI: 0.0003, 0.0039 g/cm 2 ) and BMI (95% CI: 0.0056, 0.0128 g/cm 2 ). Fat percent (95% CI: −0.0083, −0.0040 g/cm 2 ) and waist circumference (95% CI: −0.0034, −0.0007 g/cm 2 ) were indirectly associated with DMO. After controlling for the previous variables, women living in rural communities had 0.028g/cm 2 less BMD than women living in an urban area (95% CI: −0.0438, −0.0120 g/cm 2 ). However, there were not significant differences in unadjusted mean DMO between rural an urban women nor between women with or without metabolic syndrome.
