Salivary leptin concentrations in Bruneian secondary school children

Abstract

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 11–18 years) 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.
