We found diurnal weight gain to be abnormal in chronic psychosis. Nineteen chronically psychotic patients were weighed daily at 7 a.m. and 4 p.m. for 1 year. We normalized the diurnal weight gain (NDWG) 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. NDWG was 2.714 +/- 0.824% for the 19 study patients, 0.631 +/- 0.405% for 16 acutely psychotic controls and 0.511 +/- 0.351% for 29 normals. All the study patients had NDWG values above the upper limit of normal. There were no seasonal differences (p less than 0.0001) in NDWG of the study sample. Sex, diagnoses, vital signs, and drugs did not explain our findings.
我们发现慢性精神病患者的日间体重增加异常。19名慢性精神病患者在一年的时间里每天上午7点和下午4点称重。我们将日间体重增加（NDWG）标准化为百分比，方法是用下午4点的体重减去上午7点的体重，将差值乘以100，然后将结果除以上午7点的体重。19名研究患者的NDWG为2.714±0.824%，16名急性精神病对照组患者为0.631±0.405%，29名正常人组为0.511±0.351%。所有研究患者的NDWG值均高于正常上限。研究样本的NDWG没有季节性差异（p<0.0001）。性别诊断、生命体征和药物均无法解释我们的研究结果。
