To analyse the relationship between nocturnal micturition and health in 40- to 64-year-old women. A questionnaire study was carried out in 3669 randomly selected women (out of 6000 invited) in the County of Jamtland, Sweden. Questions were asked about the general health status of health, health development during the last 5 years, nocturnal micturition, parity, menstrual status, menopausal symptoms, hormone replacement therapy, cardiac diseases, diabetes and snoring. Poor health was reported by 10.4%. In 24.1% of the women health development had been unfavourable in the last 5 years. Poor health was reported by 4.7% of women without nocturnal micturition, and by 11.2, 20.1 and 39.0% (P < 0.0001) of women with one, two, and three or more nocturnal voiding episodes, respectively. In a multiple logistic regression analysis significant independent correlates of health were: one versus no nocturnal micturitions (odds ratio [OR] 2.2; confidence interval [CI] 1.5-3.3), two versus none (OR 3.2; 1.9-5.3), and three or more versus none (OR 6.5; 3.5-11.9), spasmodic chest pain (OR 6.6: CI 3.0-14.5)), irregular heart beats (OR 3.0; CI 2.1-4.3), diabetes (OR 5.1; CI 2.8-9.4), leg oedema greater than or equal to 6 days/month versus < 6 days/month (OR 23; CI 1.6-3.3), snoring: less than or equal to 3 times/week versus never (OR 1.4; CI 1.0-2.0), snoring 4-7 times/week versus never (OR 1.6; CI 1.1-2.2), being (5 years after versus bring before the menopause (OR 1.6; 95% CI 1.0-2.5), 5-9 years after versus before the menopause (OR 1.7; CI 1.0-2.9), greater than or equal to 10 years after versus before the menopause (OR 2.2; CI 1.3-3.7), diuretic treatment (OR 2.8; CI 1.7-4.6). The perceived state of health in 40- to 64- year-old women is profoundly affected by nocturia, independently of heart diseases, diabetes, snoring, age and menopausal status.
