Key result
Academic examination stress significantly reduced the Valsalva ratio in first-year medical students compared to prestress conditions, with females showing a greater reduction (mean difference 0.46) than males (mean difference 0.41).

Academic stress significantly alters the Valsalva ratio in first-year medical students, with females demonstrating a more pronounced stress response than males.
Shamshad Loni (2015) conducted an observational in Academic stress (n=56). Academic examination stress vs. Prestress condition (two months prior to examination) was evaluated on Valsalva Ratio (VR) (p=0.00044 (males), 0.00034 (females)). Academic examination stress significantly reduced the Valsalva ratio in first-year medical students compared to prestress conditions, with females showing a greater reduction (mean difference 0.46) than males (mean difference 0.41).
