背景：包括墨西哥在内的拉丁美洲国家的青年吸烟趋势正在上升。值得注意的是，虽然在青少年吸烟的高患病率已在文献中有很好的记录，很少有研究评估吸烟和二手烟（SHS）暴露对他们的呼吸系统的影响。目的：探讨吸烟和SHS暴露对八年级学生在华雷斯，墨西哥的呼吸系统健康和肺功能的影响。研究结果集中于通过肺量测定法（1秒用力呼气量[FEV 1]、1秒用力呼气量/用力肺活量比值[FEV 1/FVC]和用力呼气中期流速[FEF25%-75%]）评估300名学生的肺功能，并通过他们对标准化呼吸问卷的自我报告来评估他们的呼吸健康（吸烟行为和SHS暴露）。研究结果进行了比较三个不同的群体：1）非吸烟者/非暴露于SHS; 2）非吸烟者/暴露于SHS;和3）smokers.Results：大多数的研究参与者是14岁（85%），女性（54%），谁参加八年级在公立学校设置（56%）。大约一半的人报告说，他们的社会经济地位较低（49%），不吸烟/暴露于SHS（49%）。吸烟者的肺功能参数较低（FEV1 = 62.88 ± 10.25; FEV1/FVC = 83.50 ± 14.15; FEF25%-75% = 66.35 ± 12.55）（FEV 1 = 69.41 +/- 11.35; FEV 1/FVC = 88.75 +/- 15.75;和FEF25%-75% = 78.90 +/- 14.65），与不吸烟者/未暴露于SHS者相比，显著降低（FEV1 = 79.14 ± 13.61; FEV1/FVC = 94.88 ± 21.88; FEF25%-75% = 87.36 ± 17.02）（P
Background: Youth smoking trends among Latin American countries, including Mexico, are on the rise. Notably, although the high prevalence of smoking in teens has been well documented in the literature, few studies have evaluated the impact of smoking and secondhand smoke (SHS) exposure on their respiratory system.Objective: To investigate the effects of smoking and SHS exposure on the respiratory health and lung function among eighth-grade students in Juarez, Mexico.Methods: A cross-sectional study was undertaken on a sample of convenience. The study outcomes centered on evaluating 300 students' lung function by spirometry (forced expiratory volume in 1 second [FEV1], forced expiratory volume in 1 second/forced vital capacity ratio [FEV1/FVC], and forced mid-expiratory flow rate [FEF25%-75%]) and their respiratory health (smoking behavior and SHS exposure) by their self-reported responses to a standardized respiratory questionnaire. The study outcomes were compared among three distinct groups: 1) nonsmokers/nonexposed to SHS; 2) nonsmokers/exposed to SHS; and 3) smokers.Results: The majority of the study participants were 14 years old (85%), females (54%), who attended eighth grade in a public school setting (56%). Approximately, half reported being of low socioeconomic status (49%) and nonsmokers/exposed to SHS (49%). The lung function parameters of smokers were found to be lower (FEV1 = 62.88 +/- 10.25; FEV1/FVC = 83.50 +/- 14.15; and FEF25%-75% = 66.35 +/- 12.55) than those recorded for the nonsmokers/exposed to SHS (FEV1 = 69.41 +/- 11.35; FEV1/FVC = 88.75 +/- 15.75; and FEF25%-75% = 78.90 +/- 14.65) and significantly reduced when compared to the nonsmokers/nonexposed to SHS (FEV1 = 79.14 +/- 13.61; FEV1/FVC = 94.88 +/- 21.88; and FEF25%-75% = 87.36 +/- 17.02) (P
