Association of passive smoking exposure and blood pressure among elementary school.

Background: There are many illnesses having their base in the early periods of life, one of them are the alterations that occurs in the system and the function of the blood vessels which eventually will lead to atherosclerosis and arterial hypertension. Objective: In this research, we established the effects of tobacco smoke on blood pressure of elementary school children in al-Najaf governorate, Al-manathera town. Methods: A case control study we evaluated the blood pressure for 336 males (144 were exposed and 192 not exposed to cigarette smoking) and for 345 females (149 were exposed and 196 non exposed to cigarette smoking) from September 2016 to February 2017. A questioner was given to the pupils, after recording the weight and height, to be finished d by the parents. After full exam we removed children with acute and chronic diseases and those taking drugs, we calculated and correlate blood pressure in the exposed and non-exposed grouping. Informations were analyzed by applying independent t test by SPSS version 21. Values are revealed as mean ± SD. Results: The mean diastolic and systolic blood pressure of the exposed groups were greater than those of not-exposed groups (108.06 (4.65), 64.88 (3.79), 106.01 (4.17), 63.25 (3.37), respectively, CI: 0.95, P<0.01). Conclusion: Our study indicates that elementary school children who were exposed to passive tobacco smoking have higher systolic and diastolic blood pressures when matches to children who were not exposed.
