Context: The prevalence of hypertension is on the rise in developing countries like India. Physiological parameters such as sleep duration and water intake may be associated with hypertension in young adults. Aims: The aim is to study the association between hypertension and day and nighttime sleep duration and water intake among young adults. Setting and Design: The study was a cross-sectional study, conducted among 596 students of Government Medical College, Kannauj, aged between 17 and 22 years. Materials and Methods: Participants were classified using the diagnostic criteria of the American Heart Association. Data were recorded on a pre-designed and pretested questionnaire. Data analysis was performed using SPSS 22.0. Receiver operator characteristic curve analysis and multiple logistic regression analysis were applied. Results: The prevalence of hypertension was 34.9%, 35.9% among boys, and 33.5% among girls, respectively. Less water intake and shorter sleep duration at nighttime were found to be independent predictors of hypertension. Cutoff of sleep duration at nighttime for predicting hypertension was ≤7.6 h among boys and ≤7.1 h among girls. The sensitivity and specificity of the cutoff for sleep duration at night time in boys was 79.3% and 74.2%, respectively, and that in girls was 81.5% and 75.6%, respectively. The cutoff for water intake for predicting hypertension was ≤2.1 L for boys and ≤1.5 L for girls, respectively. The sensitivity and specificity of the cutoff for water intake in boys was 74.8% and 70.3%, and in girls was 78.3% and 71.5%, respectively. Conclusions: Young adults with longer duration of sleep during night time and more water intake had a lesser risk of hypertension.
