title: The link between fluid intake and weight gain in psychosis.
abstract: Diurnal weight gain was found to be abnormal among 44 of 77 institutionalized chronically psychotic patients. All patients were weighed and urine samples obtained weekly for 3 weeks at 7 A.M. and 4 P.M. Diurnal weight gain was normalized as a percentage by subtracting the 7 A.M. weight from the 4 P.M. weight, multiplying the difference by 100, and then dividing the result by the 7 A.M. weight. Normalized diurnal weight gain (NDWG) was 2.504 +/- 1.266% for the 44 study patients with abnormal findings, .631 +/- .405% for the 16 acutely psychotic controls, and .511 +/- .351% for 29 normals. Urine excretion was related (r = .476, p = .001) to NDWG in the subgroup of study patients with abnormal NDWG, consistent with the observation that their fluid intake exceeded fluid excretion in the afternoon.
