[10-year risk of fractures (FRAX) in people with diabetes type 2]

BONE MINERAL DENSITY AND PROBABILITY OF OSTEOPOROTIC FRACTURES IN WOMEN WITH TYPE II DIABETES MELLITUS

OBJECTIVE

The aim: To assess bone mineral density and 10-year probability of major osteoporotic and hip fractures using the Ukrainian FRAX® version for postmenopausal women with Type II diabetes mellitus and to determine the need for OP treatment according to the algorithm FRAX and BMD.

PATIENTS AND METHODS

Materials and methods: 690 females aged 50-89 years (mean age 67.0±7.7 years) were divided into two groups: Group I (n=345) was made of mostly healthy women, Group II (n=345) - patients with Type II diabetes mellitus. Bone mineral density was measured using dual-energy X-ray absorptiometry, 10-year probability of major osteoporotic and hip fractures was calculated using the Ukrainian FRAX® model.

RESULTS

Results: Bone mineral density and 10-year risk of major osteoporotic and hip fractures did not differ depending on the Type II diabetes mellitus presence, however the frequencies of low-energy, vertebral and all previous fractures were higher in Group II. 19% of women with diabetes mellitus and 38% of healthy ones required antiosteoporotic treatment according to dual-energy X-ray absorptiometry and only 8% and 2%, respectively, according to the FRAX. These indices became higher after recalculation of FRAX taking into account bone mineral density, however they were lower in patients with diabetes mellitus compared to the corresponding rate in the Group I (FRAX (high risk) + bone mineral density: 26% and 41%; χ2 = 18.2; p<0.001).

CONCLUSION

Conclusions: The use of FRAX in combination with bone mineral density resulted in an increased necessity for antiosteoporotic treatment, indicating the urgency of using both indices for osteoporotic fractures prediction in patients with Type II diabetes mellitus.

Risk Factors for Chronic Non-Communicable Diseases and Osteoporotic Fractures in a Middle and Elderly-Aged Population

Aim. To study the associations of risk factors for chronic non-communicable diseases (CNCDs) and osteoporotic fractures (OFs) in a population sampling over 50 years. Materials and Methods. The data of a cross-sectional population-based study obtained in the Russian part of the international project HAPIEE (Novosibirsk) are analyzed. The present analysis comprised 7363 men and women aged 50–69 years old. We have assessed the frequency of OFs for the last 12 months and risk factors of CNCDs. Cross-sectional associations between OF history and potential determinants were analyzed using multivariable-adjusted logistic regression. Results. The frequency of OFs in the last 12 months was 3.6% (3.2% in men and 4.0% in women, p = 0.074). In men, the probability of OFs increased with an elevation of blood pressure (BP), high-density lipoprotein cholesterol (HDL-C), ethanol consumption, and reduced with increased body mass index (BMI). In women, the probability of a fracture increased with current smoking and an increased duration of post-menopause and reduced with an increase in triglycerides (TG) levels, independently of other factors. Conclusions. A syndemia of risk factors, both generally recognized for OFs (BMI, tobacco smoking, alcohol consumption, postmenopausal duration) and new factors associated with CNCDs (BP, HDL, TG), have been defined.

The Risk of Osteoporotic Forearm Fractures in Postmenopausal Women in a Siberian Population Sample

The reduction in bone and muscle mass increases in menopausal women and poses a threat to the loss of self-dependence in the elderly. The aim of the study was to assess the frequency of osteoporotic forearm fractures (OFF) in postmenopausal women and to study their association with risk factors for chronic non-communicable diseases (NCD). The study was based on the Russian arm of the Health, Alcohol and Psychosocial Factors In Eastern Europe (HAPIEE) project (Novosibirsk). In a subsample of postmenopausal women aged 55–84 years old (n = 2005), we assessed the history of OFF during the last 3 years and risk factors for fracture and common NCD/. Cross-sectional associations between OFF history and potential determinants were analyzed using multivariable-adjusted logistic regression. A history of OFF in the last 3 years was found in 3.9% women. In a multivariable-adjusted model, the risk of OFF was directly associated with smoking in the past (OR = 2.23; 95% Cl 1.10–4.55), total cholesterol level higher than 200 mg/dL (OR = 1.98; 95% Cl 1.19–3.29), and it was inversely associated with body mass index (OR = 0.91; 95% Cl 0.86–0.96). In studied population sample of postmenopausal women the cross-sectional determinants of osteoporotic forearm fractures were smoking in the past and high total cholesterol value; body mass index protectively related to the risk of osteoporotic fractures. These findings might have implications for fracture prevention in postmenopausal women.
