A brief note on serum calcium levels in schizophrenics and controls

The present investigation examined the relationship between serum calcium levels and schizophrenic disorder. Unlike earlier studies a wider range of diagnoses was surveyed, subjects were limited to first time admission, and the relationship of socio-demographic factors to the hypothesized biological risk factor was assessed. Analysis revealed no significant differences in levels of serum calcium between schizophrenics and four nonschizophrenic comparison groups, nor were any one of several socio-demographic factors found to correlate significantly with serum values. Some risk factors, however, differentiated between schizophrenics and nonschizophrenics. They were being single, poor employment history, and reason for admission. A more promising avenue for further research in the area is outlined.
