Prevalence of undiagnosed hyperglycemia and hypertension among middle-aged adults in Vietnam: A community-based study

Background: The information on prevalence of undiagnosed hyperglycemia, and hypertension among the adult in Vietnam is limited. The aim of this study was to identify the prevalence of undiagnosed intermediate hyperglycemia, hyperglycemia, and hypertension and some associated factors among adults aged ≥40 years living in Ba Vi district in Hanoi, Vietnam. Methods: A cross-sectional study was conducted among 1814 adults aged ≥40 years nine communes in Ba Vi district, a semi rural area, in Hanoi, Vietnam. Lists of the adults aged ≥40 years living in nine communes, who reported undiagnosed for hypertension, and diabetes, were made. From the lists, the participants were randomly selected based on the selection criteria. Participants were people who reported they are free of hypertension, diabetes, prediabetes at the day of data collection. Participants were collected information on sociodemographic characteristics, blood pressure measurement, and 3 ml fasting venous blood samples by certified phlebotomists. The main study outcomes variables were intermediate hyperglycemia, hyperglycemia, and hypertension. Results: Prevalence of undiagnosed intermediate hyperglycemia, hyperglycemia, and hypertension among the participants were 47.8 %, 8.2 %, and 40.0 %, respectively. Higher prevalence of undiagnosed intermediate hyperglycemia (53.3 % vs 46.2 %), hyperglycemia (13.5 % vs 7.9 %), and high blood pressure (52.8 % vs 33.9 %) were found among males compared with females. Conclusion: High prevalence of undiagnosed intermediate hyperglycemia, hyperglycemia, and hypertension were found in the middle-aged adults in Vietnam. Improving the individual's awareness and early screening for diabetes, and hypertension in adults for timely management are necessary
