Abstract:
Objective To investigate the harmless biochemical indicators for early screening of populations at high risk of suicide .Methods Seven hundred and twenty-seven new recruits were investigated according to self-rating idea of suicide scale (SIOSS) in the first month of recruitment in 2014.Twenty-five recruits (originally 27 recruits, but 2 recruits were absent from biochemical tests ) whose SIOSS scores were less than 12 were recognized as the suicidal ideation group. Another 25 recruits whose SIOSS scores were more than 12 were randomly selected as the control group .Saliva samples of the 50 recruits were collected for biochemical analysis after one month and three months of training , respectively .After three months of training , the SIOSS was also used for evaluation of suicidal ideation .Results After one-month training , the concentrations of Ca , Mg, amylase ( Amy ) and salivary acid ( SA ) in saliva were demonstrated to be statistically different between the suicidal ideation group and the control group ( P <0.05 ), but there was no significant linear correlation between these indicators and the SIOSS (P>0.05).After three-month training, the concentrations of Ca, Mg, Amy and SA in saliva between the two groups showed no significant difference (P>0.05).Conclusion After the first month training , changes in the biochemical compositions were found in the saliva of the screened recruits with suicidal ideation, which may be associated with the stress response of the body .The biochemical indicators in saliva lack specificity for suicidal ideation .
