Abstract:
Objective:To analyze the association between short term PM 2.5 exposure and high blood pressure in adolescents and its modification effect of overweight and obesity, and to provide a reference for the refined management of students physical health and the scientific prevention and controlling of air pollution.
Methods:A total of 148 956 junior high school students and senior high school students who passed the annual physical examination data of middle school students in Beijing from 2017 to 2018 were selected; The inverse distance weighted interpolation method was used to get the meteorological elements and air quality of the research area; Linear mixed effect model was used to estimate the cumulative lag effect of short term PM 2.5 exposure on systolic and diastolic blood pressure within 7 days, and analyze the modification effect of overweight and obesity on the association between short term PM 2.5 exposure and high blood pressure in adolescents.
Results:From September 1, 2017 to June 30, 2018, the average concentration of PM 2.5 was (56.53±45.85)μg/m 3; The detection rate of overweight and obesity was 34.22%, and the detection rate of high blood pressure was 8.03%. The cumulative lag effect of PM 2.5 on systolic blood pressure in overweight and obesity group was the largest at lag07, that is, the daily average concentration of PM 2.5 increased by 10 μg/m 3 was significantly correlated with higher systolic blood pressure ( OR =1.05,95% CI =1.03-1.07); the cumulative lag effect of PM 2.5 on systolic blood pressure in non overweight and obese group was the largest at lag05, that is, the daily average concentration of PM 2.5 increased by 10 μg/m 3 was significantly correlated with higher systolic blood pressure ( OR =1.04,95% CI =1.02-1.06). Short term exposure to PM 2.5 did not affect the high diastolic blood pressure in adolescents. Overweight and obese adolescents were more susceptible to high blood pressure caused by short term PM 2.5 exposure within 3 days of cumulative lag (lag01-lag03).
Conclusion:The short term exposure of PM 2.5 has a significant positive correlation with adolescent blood pressure, and shows a lag effect. Overweight and obese adolescents have higher blood pressure after PM 2.5 short term exposure.
