Undiagnosed hypertension and associated factors among adults in the urban field practice area of AIIMS Raipur: A community-based screening survey

INTRODUCTION: Undiagnosed hypertension (HTN) increases the risk of severe consequences such as chronic kidney disease (CKD), hypertensive retinopathy, heart failure, and stroke. Population-based screening can be used to expose the hidden diseased mass with active disease. Thus, a screening survey was conducted to estimate the proportion of people with HTN among apparently healthy adults of age ≥30 years residing at the urban field practice area (UHTC) of AIIMS, Raipur, and also determine the predictors of undiagnosed HTN among the study participants. METHODOLOGY: This was a community-based cross-sectional study conducted over 2 months duration in the Ramnagar area, which comes under the urban field practice area of AIIMS Raipur using the STEPS tool is an acronym of study tool provided by WHO i.e. STEPwise approach to NCD risk factor surveillance consisting of three steps viz. questionnaire for behavioural risk factors, physical measurements and biochemical measurements. RESULTS: In this study, 24.2% (95%, confidence interval [CI]: 20.1–28.2) of participants screened positive for HTN. The proportion of males who screened positive for HTN was 28.8% (95% CI: 22.6–35), whereas the proportion of females who screened positive for HTN was 19.6% (95% CI: 14.3–25). In this study, elderly (>60 years), male gender, daily tobacco use, greater waist circumference (male >90 cm and female >80 cm), and daily salt intake of more than 5 g were found to have higher odds of having HTN. CONCLUSION: The prevalence of undiagnosed HTN in the UHTC of AIIMS Raipur was quite high.
