Among 29,505 adults aged ≥20 years, the authors defined nocturia as ≥2 nighttime voids. Hypertension was identified through self-report, antihypertensive drug use, or measured systolic/diastolic blood pressure ≥140/90 mmHg. Multivariable logistic regression models showed that participants with nocturia had a higher odds of hypertension (OR 1.36; 95% CI 1.28–1.45). The association was consistent across sex, age, race, and BMI subgroups. Furthermore, the odds of hypertension increased with the severity of nocturia (P for trend <0.0001) and with higher grades of hypertension. The study is limited by its cross-sectional design, which cannot establish causality, and by reliance on some self-reported data.
