  1. Polydipsia and water intoxication in a long-term psychiatric hospital.

    Article - En anglais

    This cross-sectional survey attempts to establish the prevalence of polydipsia and water intoxication at a state hospital (N=360) using staff diagnosis, specific gravity of the urine (SPGU), weight changes, and chart review.

    There were 150 [42%, 95% confidence interval (Cl) 37 - 47% ] patients diagnosed as polydipsic by the staff or by SPGU.

    At least 93 (26%, Cl 21 - 30%) had primary polydipsia not explained by other causes.

    Chart review identified 17 (5%, Cl 3 - 7%) patients with a history of water intoxication.

    Using a case-control study design, schizophrenia, extended duration of hospitalization, and heavy smoking were associated with primary polydipsia in a logistic regression analysis (respective odds ratios were 1.6,1.8, and 3.6).

    All patients with a history of water intoxication were Caucasian (versus 83% in those without a history) and had significantly more extended hospitalizations (94 vs. 49%). Future case-control studies should combine longitudinal identification of true cases and controls and exhaustive collections of clinical information in a standardized way.
