Scholarcy highlights

  • Cultural practices may compromise the accuracy of salivary hormone measurements and must be considered when designing human biology research protocols
  • This study aims to evaluate the acute effect of one common human practice—chewing betel nut—on the measurement of salivary cortisol levels under field conditions
  • Saliva was collected in time series from each participant before and at 0, 15, 30, 45, 60, and 75 min after chewing betel nut
  • Samples were analyzed by radioimmunoassay and cortisol levels were compared across time using linear mixed effects modeling
