Knowledge and associated factors towards type 2 diabetes among a rural population in the Red River Delta region, Vietnam.

INTRODUCTION: Knowledge about type 2 diabetes (T2D) and attitude towards the condition are known to affect compliance and play an important role in diabetes management. T2D knowledge is a prerequisite for individuals and communities to take action on control of the disease.
METHODS: A cross-sectional study was designed to identify knowledge and related factors towards T2D, risk factors, complications, prevention and treatment of the disease. A total of 2580 subjects representative of the general population aged 40-64 years was recruited from a typical province of Red River Delta region, Vietnam. The trained surveyors interviewed subjects directly to collect data, using a structured questionnaire. To evaluate the overall knowledge of T2D, 14 questions were used to calculate the 100 points. Total knowledge score was classified into the following four categories: highly insufficient (≤25 points), insufficient (26-50 points), satisfactory (51-75 points), and highly satisfactory (>75 points). Association between inadequate knowledge (<50 points) and variables was evaluated using multivariate logistic regression.
RESULTS: The highly insufficient, insufficient, satisfactory, and highly satisfactory levels of the overall knowledge were 75, 17.9, 6.8, and 0.3%, respectively. Of the total population, more than 65% thought that there is no cure for diabetes, and more than 90% did not know the essential combination of drugs, diet, and physical activity in T2D treatment. Less than 10% of the population understood the concept of T2D, its risk factors, complications, approaches to prevention and treatment. The rural-urban difference of T2D knowledge was found in rates of understanding at least one risk factor (34.8% vs 63%), all the three methods for T2D prevention (1.7% vs 10.3%), and three combined approaches for T2D treatment (8.9% vs 16.4%). Age, residence, educational level, and occupation were the most significant factors associated with inadequate knowledge.
CONCLUSIONS: The study shows a low level of diabetes knowledge among the general population aged 40-64 years in the Red River Delta, and significantly lower awareness in rural areas compared with urban areas. The limited awareness has indicated the urgent need for communication and education to improve the T2D knowledge of the Vietnamese population on risk factors, serious level, complications, prevention and treatment, taking into account the age, residence, educational level, and occupation of the subjects.
