Nocturia is receiving increasing
awareness from the international scientific community. Little is known about
the natural history.
Aims of Study:
To study the natural history or nocturia in women 40-60 years of age.
Methods:
A questionnaire was sent to 4,000 women randomly recruited from the Civil Registration
System in Denmark. Incidence and remission rates were defined as the transitions
of symptoms regarding two nightly voids as the cut-off level.
Results:
Inclusion rates = 71.7% (baseline) and 57.0% (one-year follow), respectively.
Test-retest of the question in 100 women showed overall agreement = 0.99 and
Kappa coefficient = 0.88.
