Methods: Multivariate Cox proportional-hazards analysis using data from a total of 1,415 women with natural menopause. We included 163 women with hysterectomy, oophorectomy, and estrogen therapy as censored data. Results: The median age of natural menopause was 50 years. In the multivariate Cox proportional hazards, smoking was associated with earlier age at natural menopause for the three cohorts (2000, 2006, and 2010). Current smokers had a 35% higher risk of earlier natural menopause (hazard ratio [HR] 1.35, 95% confidence interval [CI] 1.12, 1.62) and former smokers had a 27% higher risk of earlier natural menopause (HR 1.27, 95% CI 1.09, 1.50), in comparison with never-smokers. Women with 8 years or more of formal education had a 33% lower risk of earlier natural menopause (HR 0.67, 95% CI 0.50, 0.89) than women with no education, and women who were separated, widowed, or divorced had a 15% higher risk of earlier natural menopause (HR 1.15, 95% CI 1.00, 1.31) in comparison with married women. Marital status and parity were associated with later age at natural menopause only in 2006. Conclusions: We found significant associations of age at natural menopause with reproductive and lifestyle factors similar to some studies of women from developed countries.

Abstract

Objective:

The aim of this study was to assess the status of bone mass, microarchitecture, and factors associated with vertebral fracture in postmenopausal women with type 2 diabetes mellitus (T2DM).

Methods:

We consecutively enrolled 285 women (aged 60.7 ± 6.9 y) with T2DM who underwent bone mineral density (BMD) and trabecular bone score (TBS) assessment using dual-energy x-ray absorptiometry; T8-S1 lateral spine radiographs; laboratory evaluation; and interviews regarding clinical risk factors based on the fracture risk assessment tool (FRAX).

Results:

Low bone mass and deteriorated bone microarchitecture were observed in 63.2% and 72.6% of women with T2DM, respectively. TBS was correlated with lumbar spine, femoral neck, and total hip BMD. Significant differences in TBS were observed between the normal BMD, osteopenia, and osteoporosis groups. Age, vertebral fracture, and bone-specific alkaline phosphatase significantly differed among groups with different T scores or those classified by TBS categories. Bone-specific alkaline phosphatase was inversely correlated with BMD and TBS but positively with glycated hemoglobin. BMD showed a weaker correlation with vertebral fracture than TBS, TBS and BMD, FRAX, and TBS-adjusted FRAX.

Conclusions:

Low bone mass and deteriorated TBS were noted in approximately two-thirds of T2DM women and was also associated with vertebral fracture. In addition to aging, poor glycemic control may play an important role in bone remodeling, which may be associated with changes in bone strength in T2DM women. Bone strength together with clinical risk factors has the strongest association with fracture, and may potentially be useful to identify women with T2DM at risk.
