Salivary leptin concentrations in Bruneian secondary school children

Objective:To investigate the association between leptin levels and body mass index in Bruneian secondary school students.Methods:The body mass index of Bruneian secondary school students(aged 11–18years) was determined before collecting their saliva using the passive drool technique.Salivary leptin concentration was determined by ELISA.Results:Correlation and partial correlation(controlled for age) analyses showed no significant differences between the levels of salivary leptin of normal weight and overweight students.Conclusions:No significant increase in the salivary leptin concentration was observed in overweight compared with normal weight Bruneian secondary school students.
