Weight-neutral effect of once-daily insulin detemir in Chinese type 2 diabetes patients: subgroup analysis of the SOLVE study

Prevalence, treatment patterns and control rates of metabolic syndrome in a Chinese diabetic population: China Cardiometabolic Registries 3B study

AIMS/INTRODUCTION

To investigate the prevalence and risk factors of metabolic syndrome (MetS) in Chinese type 2 diabetes mellitus patients, and assess the effect of MetS on the treatment patterns and blood glucose, blood pressure and blood lipids goal achievements.

MATERIALS AND METHODS

Data from 25,454 type 2 diabetes mellitus patients including demographic data, anthropometric measurements, treatment patterns, and blood glucose and lipid profiles were retrospectively analyzed.

RESULTS

Using modified Adult Treatment Panel III MetS criteria, the prevalence of MetS was 57.4% in type 2 diabetes mellitus patients. Multivariable logistic regression analysis showed that type 2 diabetes mellitus patients, who also fulfilled the criteria for MetS, tended to be women, living in the northeast, with a diabetes duration ≥5 years and leading a sedentary lifestyle. Most MetS (53.4%) and non-MetS (57%) diabetes patients received oral hypoglycemic drugs. Insulin or insulin combination therapies were more applied in MetS (37.5%) than in non-MetS (33.1%) diabetes patients, and the percentages of MetS diabetes patients receiving antihypertensive and lipid-modulating drugs were 52.9% and 28.2% vs 38.3% and 19.3% of the non-MetS diabetes patients. Just 37.5%, 15.6% and 32.9% of the MetS diabetes patients vs 54.6%, 45.6% and 40.4% of the non-MetS diabetes patients achieved the individual target goals for control of blood glucose (glycosylated hemoglobin <7%), blood pressure (systolic blood pressure <130 mmHg, diastolic blood pressure <80 mmHg) and blood lipids (total cholesterol <4.5 mmol/L), whereas just 2.1% achieved all three target goals.

CONCLUSIONS

MetS with a high prevalence in Chinese type 2 diabetes mellitus patients is associated with poor blood glucose, blood pressure and blood lipids control rate.

Prevalence of Obesity and Its Influence on Achievement of Cardiometabolic Therapeutic Goals in Chinese Type 2 Diabetes Patients: An Analysis of the Nationwide, Cross-Sectional 3B Study

Background

There are few data on the prevalence of obesity and its influence on achieving blood glucose, blood pressure, and blood lipid (3B) goals in Chinese type 2 diabetes outpatients.

Methods

Patient demographic data, anthropometric measurements, medications, and blood glucose and lipid profiles of 24,512 type 2 diabetes patients from a large, geographically diverse study (CCMR-3B) were analyzed. Using cut-points for body mass index (BMI) and waist circumference (WC) recommended by the Working Group on Obesity in China, overweight and obesity were defined as BMIs of 24–27.9kg/m² and ≥28.0kg/m². Central obesity was defined as a waist circumference ≥80cm in women and ≥85cm in men. The 3B therapeutic goals were HbA1c<7.0%, BP<140/90mmHg and LDL-C<2.6mmol/L.

Results

Overall, 43.0% of type 2 diabetes patients were overweight and 16.7% were obese; 13.3% of overweight and and10.1% of obese patients achieved all the 3B target goals. Overweight or obese patients were less likely to achieve 3B goals than those with normal BMIs. More than a half the overweight or obese patients (69.6%) were centrally obese. Patients with abdominal obesity were less likely to achieve cardiometabolic targets than those without abdominal obesity. In multivariate logistic regression analysis, female, higher BMI and waist circumference, smoking, drinking, sedentary lifestyle, and longer diabetes duration were significantly correlated with failure to achieve 3B control goals.

Conclusions

Obesity is highly prevalent and associated with poor 3B control in Chinese type 2 diabetes patients. In clinical practice, more attention and resources should focus on weight loss for such patients.
