Development of nocturia in relation to health, age and the menopause.
OBJECTIVE
To analyse the relationship between nocturia, age, the menopausal transition, parturition and hormone replacement treatment (HRT) in women.


METHODS
A questionnaire study was carried out in 3669 randomly selected women (out of 6000 invited) in the County of Jämtland, Sweden. Questions were asked about health, the occurrence of somatic diseases and symptoms, habits, health care and medication.


RESULTS
In univariate analyses age, menopausal state and HRT, but not parturition, were associated with increased nocturia. In a multiple logistic regression analysis, independent correlates for two or more nocturnal micturition episodes versus no more than one episode were: health, poor versus good 2.9 (2.1-3.8); <5 years after the menopause versus before 1.8 (1.3-2.5); 5-9 years after the menopause versus before 2.1 (1.5-3.0); > or =10 years after the menopause versus before 3.1 (2.3-4.2). Age and HRT were deleted by the logistic regression model.


CONCLUSIONS
The present data indicate that menopausal state, but not age, parturition and HRT are independent correlates of nocturia in 40-64-year-old women.
