Men suffer more complications from diabetes than women despite similar glycaemic control and a better cardiovascular risk profile: the ADCM study 2008

Abstract

Abstract

Background:

Gender differences in glycaemic control and diabetes’ complications have been well studied overseas but not locally. Gender is one of the non-modifiable factors for the diabetes patient but it is an important factor for effective personalized diabetes care. This paper examined the gender differences in glycaemic control and diabetes’ complications.

Methods:

This was a registry-based observational study from May–December 2008. An online standard case record form was available for site data providers to register their diabetes patients aged 18 years old and above annually. Demographic data, diabetes duration, treatment modalities, as well as various risk factors and diabetes complications were reported. Multivariate analysis was performed.

Results:

A total of 20,646 diabetes patients were included. The majority (99.2%) had been diagnosed with type 2 diabetes mellitus (T2D); 42.8% of the sample were men; 57.1% were Malay. The mean age was 58.0 years (standard deviation (SD) = 11.49) with 77.6% of the sample being 50 years old and above. Despite similar diabetes control (HbA1c < 6.5%), females suffered more microvascular complications (estimated glomerular filtration rate (eGFR) <60 mls/min: X² = 753.54, P = <0.001) while men suffered more from macrovascular complications (ischaemic heart disease (X² = 57.61, P = <0.001) and stroke (X² = 13.87, P = <0.001)). Multivariate logistic regression analyses showed that T2D men were more likely to suffer from stroke (odds ratio (OR) = 1.21, 95% confidence interval (CI) = 0.89–1.64), ischaemic heart disease (OR = 1.55, CI = 1.35–1.78) and nephropathy (OR = 1.59, CI = 1.44–1.75).

Conclusion:

We observed that men suffered more diabetes-related complications despite similar glycaemic control and better risk factor control. This finding requires further verification from future studies.
