Abdominal obesity is a major risk factor for diabetes. Dual-energy x-ray absorptiometry (DXA) of the lumbar spine provides an index of abdominal fat.
Our objective was to examine the hypothesis that DXA-derived abdominal fat measurement in women undergoing osteoporosis investigation predicts risk for subsequent diagnosis of diabetes.
This historical cohort study was derived from the Manitoba Bone Density Program Database for the Province of Manitoba, Canada.
30,252 nondiabetic women aged 40 yr and older were referred for baseline osteoporosis assessment with DXA between January 1990 and March 2007.
Each woman's longitudinal provincial health service record was assessed for the presence of diabetes diagnosis codes after DXA testing.
During 5.2 + or - 2.6 yr of observation, 1252 (4.1%) women met the case definition for diabetes. A greater proportion of abdominal fat from spine DXA was strongly related to subsequent diabetes diagnosis in models adjusted for age, body mass index, and other comorbidities. Those in the highest quintile had 3.56 (95% confidence interval = 2.67-4.75) times the risk for subsequent diabetes diagnosis compared with those in the lowest (reference) quintile. Fat from hip DXA was not predictive of subsequent diabetes after adjustment for the same variables (1.00, 95% confidence interval = 0.79-1.26).
Predictive information about diabetes risk can be obtained from spine DXA scans performed for osteoporosis risk assessment. This is consistent with evidence linking abdominal fat with insulin resistance and the metabolic syndrome.
The aim of this study was to identify corresponding body mass index (BMI) and waist circumference cut-offs for equivalent levels of insulin sensitivity in a Middle Eastern immigrant population compared with native Swedes.
Citizens of Malmö, Sweden aged 30 to 75 years, who were born in Iraq or Sweden, were in 2010-2012 invited to participate in a health examination including anthropometrics, oral glucose tolerance test, fasting samples and interviews concerning sociodemographic factors and lifestyle behaviours.
In total, 1176 individuals born in Iraq and 688 born in Sweden, without previously diagnosed type 2 diabetes, participated in the study. In normal weight participants (BMI?

The aim of this study was to assess prevalence of metabolic syndrome and its components according to different criteria in the population of bank employees in St. Petersburg, Russia.
A total of 1,600 office workers were screened at their working places from the Sberbank state bank in St. Petersburg. All subjects were interviewed by a special questionnaire that included personal data, smoking status, physical activity, alcohol consumption, and medical history. Anthropometry measurements, vital signs, and fasting blood samples were obtained. Serum lipids and plasma glucose were measured.
In all, 1,561 responders were included in the final analysis. Hypertension (HTN) was observed in 35.2% of subjects (64% in males and 25.4% in females), abdominal obesity (AO) according to Internation Diabetes Federation (IDF) criteria in 45.6% (51.5% in males and 44.0% in females), high triglyceride levels in 28.4%, low high-density lipoprotein cholesterol (HDL-C) levels in 23.9%, and elevated fasting glucose over 5.6 mmol/L in 28.4% of subjects. AO associated with HTN was observed in 24.3%. Metabolic syndrome according to IDF criteria was diagnosed in 21.5% (17.9% in females and 34.6% in males, P
