Epidemiological studies have demonstrated that environmental noise exposure is associated with hypertension in middle-aged and older populations, but the relationship in the young subpopulation and between the genders is still unclear. This panel study investigated effects of environmental noise exposure on 24-h ambulatory blood pressure in 60 adults aged 18–32 years. Individual noise exposure and personal blood pressure were measured simultaneously for 30 males and 30 females. Linear mixed-effects regression models were applied to estimate effects. Total subjects (56.6±16.5 A-weighted decibels (dBA)) had transient elevations of 1.15 (95% CI=0.86–1.43) mmHg SBP and 1.16 (0.93–1.38) mmHg DBP at daytime, as well as 0.74 (0.21–1.26) mmHg SBP and 0.77 (0.34–1.20) mmHg DBP at nighttime, significantly associated with a 5-dBA increase in noise exposure. Such effects on SBP and DBP still persisted at the 30- and 60-min time-lagged noise exposure. Per 5-dBA increase in 24-h average noise exposure was significantly associated with sustained increments of 1.15 (0.76–1.54) mmHg SBP and 1.27 (0.96–1.58) mmHg DBP in males (57.4±16.0 dBA), as well as the higher levels of 1.65 (1.36–1.94) mmHg SBP and 1.51 (1.27–1.75) mmHg DBP in females (55.9±17.0 dBA). We found that environmental noise exposure may have elevated effects on adults’ blood pressure. Young females are more susceptible to noise exposure than males.
