Prevalence and Clinical Profile of Undiagnosed Diabetes Mellitus: Data from a Tertiary Hospital.

BACKGROUND

The prevalence of diabetes mellitus in Vietnam is relatively low compared to other Asian countries, but it is accelerating with the economic and cultural transition. This study aimed to estimate the current prevalence and clinical profile of undiagnosed diabetes mellitus in a tertiary hospital in the south of Vietnam.

METHODS

A cross-sectional investigation was conducted to recruit 1, 250 participants, who were at least 18 year-old and randomly sampled from Cho Ray Hospital, Ho Chi Minh City, Vietnam. Fasting plasma glucose concentration and HbA1c were measured for each individual. The American Diabetes Association criteria were used to diagnose diabetes. Demographic data and other clinical characteristics of diabetes were also documented, including age, sex, residence, educational status, weight, height, waist and hip circumferences, blood pressure, familial history of diabetes, and lipid profile.

RESULTS

The prevalence of undiagnosed diabetes mellitus was 7.5% in the population studied. Age, waist circumference, waist-hip ratio, body mass index, and hypertension, as well as dyslipidaemia were well-correlated with the diabetes rate.

CONCLUSION

The prevalence of undiagnosed diabetes mellitus is increasing far more than expected. Newly diagnosed diabetic patients usually presented with multiple comorbidities, including overweight/ obesity, hypertension, and dyslipidaemia.
