This study aimed to determine the relationship between the duration of mobile phone usage and the changes in lordotic, kyphotic, and forward head angles in male students with endomorphic body types in high school boys.
This descriptive-correlational study was conducted on male students aged 13 to 15 years in high school boys in Farooj City during the academic year 2022-2023. Using the Morgan table, 200 individuals were selected from the population through simple random sampling, with an average weight of 58.06 ± 9.26 kilograms and an average height of 163.94 ± 7.66 centimeters. Various tools and instruments such as an informed consent form, stadiometer, digital scale, caliper, tape measure, smartphone addiction scale questionnaire, kyphometer, flexible ruler, and craniovertebral angle measurement device were used for data collection. The data were analyzed using the Kolmogorov-Smirnov test to check for normality. Pearson and Spearman correlation coefficients were used to determine the relationship between variables, and the analyses were carried out at a 95% confidence level. Data analysis was performed using SPSS version 20.
The results of Spearman's correlation coefficient showed that there is a significant positive relationship between the level of addiction to smartphones and the kyphotic angle (r = 0.416, = 0.0001), lordotic angle (r = 0.185, = 0.009), and forward head angle (r = 0.425, = 0.0001) among male students in high school boys with an endomorphic body type.
The study found that male students with an endomorphic body type who have a higher addiction to smartphones tend to have increased kyphotic, lordotic, and forward head angles. This is concerning, considering adolescents are more sensitive to growth and typically spend much time on their phones. Educating this group on proper smartphone use is essential to avoid potential adverse effects like spinal column abnormalities. The suggested solutions include paying attention to proper posture while sleeping, sitting, walking, and standing and using educational media to study.
本研究旨在确定高中男生中具有内胚层体型的男学生使用手机的时长与脊柱前凸、脊柱后凸和头部前倾角度变化之间的关系。
本描述性相关性研究于2022 - 2023学年在法鲁吉市的高中13至15岁男学生中进行。使用摩根表,通过简单随机抽样从总体中选取200名个体,平均体重为58.06±9.26千克,平均身高为163.94±7.66厘米。使用各种工具和仪器,如知情同意书、身高计、数字秤、卡尺、卷尺、智能手机成瘾量表问卷、后凸仪、软尺和颅椎角测量装置进行数据收集。使用柯尔莫哥洛夫 - 斯米尔诺夫检验分析数据以检查正态性。使用皮尔逊和斯皮尔曼相关系数确定变量之间的关系,并在95%置信水平下进行分析。使用SPSS 20版进行数据分析。
斯皮尔曼相关系数结果表明,在具有内胚层体型的高中男学生中,智能手机成瘾程度与脊柱后凸角度(r = 0.416,P = 0.0001)、脊柱前凸角度(r = 0.185,P = 0.009)和头部前倾角度(r = 0.425,P = 0.0001)之间存在显著正相关。
研究发现,对智能手机成瘾程度较高的具有内胚层体型的男学生往往脊柱后凸、脊柱前凸和头部前倾角度增大。鉴于青少年对生长更为敏感且通常在手机上花费大量时间,这令人担忧。对该群体进行正确使用智能手机的教育对于避免脊柱异常等潜在不良影响至关重要。建议的解决方法包括在睡眠、坐、走和站立时注意正确姿势,并使用教育媒体进行学习。
