Aging Effects on Esophageal Transit Time in the Upright Position During Videofluoroscopy.

OBJECTIVES

The purpose of this study was to examine age-related effects on esophageal transit times (ETT) among healthy adult participants.

METHODS

A total of 175 healthy, non-dysphagic participants underwent a modified barium swallow study (MBSS), and ETT was recorded for two standardized swallowing tasks. Differences across age groups were determined using Kruskal-Wallis test. Relationships between an Esophageal Clearance (Modified Barium Swallow Impairment Profile Component 17) score and ETT were also explored.

RESULTS

No significant differences were observed in ETT across age groups for nectar-thickened liquid ( = .335) or pudding ( = .231) consistencies. No significant differences were observed between males and females in ETT for either the nectar ( = .112) or pudding trial ( = .817). For nectar, the mean ETT for patients with Component 17 scores of 2 or greater were significantly higher than that of participants with a score of 0 ( < .0001). For pudding, participants with a score >0 demonstrated significantly higher mean ETT compared to participants with a score of 0 (with  = .0008 and  < .0001, respectively).

CONCLUSION

Study findings failed to support age-related or sex-related differences in ETT for two standardized swallowing tasks administered during a MBSS in healthy individuals. The normative values following a standardized protocol in this study provide guidance in clinical interpretation of esophageal function.
