This cross-sectional study aimed to identify gender differences in the cervical postures when young adults were using mobile phones, as well as the correlations between the postures and the digital devices use (computer and mobile phone). Questionnaires regarding the habits of computer and mobile phone use were administrated to 429 subjects aged from 17 to 33 years old (19.75 ± 2.58 years old). Subjects were instructed to stand habitually and use a mobile phone as in daily life; the sagittal head and cervical postures were measured by head flexion, neck flexion angle and gaze angle. Male participants had a significantly larger head flexion angle (96.41° ± 12.23° vs. 93.57° ± 12.62°, p = 0.018) and neck flexion angle (51.92° ± 9.55° vs. 47.09° ± 9.45°, p < 0.001) than females. There were significant differences in head (F = 3.62, p = 0.014) and neck flexion (F = 3.99, p = 0.009) between different amounts of computer use. Practitioner Summary: We investigated possible gender differences in head and neck postures of young adults using mobile phones, as well as the potential correlations between these postures and digital device use. We found that males displayed larger head and neck flexion angles than females, which were associated with the amount of computer use.
这项横断面研究旨在确定年轻人使用手机时颈部姿势的性别差异，以及这些姿势与数字设备使用（电脑和手机）之间的相关性。对429名年龄在17至33岁（平均年龄19.75±2.58岁）的受试者进行了关于电脑和手机使用习惯的问卷调查。受试者被要求习惯性站立并像日常生活中那样使用手机；通过头部前屈、颈部前屈角度和注视角度来测量矢状面头部和颈部姿势。男性参与者的头部前屈角度（96.41°±12.23°对93.57°±12.62°，p = 0.018）和颈部前屈角度（51.92°±9.55°对47.09°±9.45°，p < 0.001）均显著大于女性。不同电脑使用量的受试者在头部（F = 3.62，p = 0.014）和颈部前屈（F = 3.99，p = 0.009）方面存在显著差异。从业者总结：我们调查了年轻人使用手机时头部和颈部姿势可能存在的性别差异，以及这些姿势与数字设备使用之间的潜在相关性。我们发现男性的头部和颈部前屈角度大于女性，且这与电脑使用量有关。
