【摘要】：目的了解青春早期青少年食指(2D)∶无名指(4D)指长比与青春发育、抑郁心理及攻击行为的关联,为探讨生长发育对健康行为及心理的影响提供依据。方法整群抽取上海市某九年一贯制学校10~14岁182名青少年学生参加平板计算机辅助自填问卷调查,了解青少年的身体发育及抑郁心理、攻击行为状况,通过游标卡尺测量被调查者左右手2D和4D指长。结果青春早期青少年女生左右手的2D∶4D指长比均数均高于男生(左手:0.988与0.971;右手:0.996与0.981),差异有统计学意义(t值分别为3.19,3.32,P值均0.05)。男性青少年变声的发生与左手2D∶4D低指长的关联在10~12岁青少年中已然出现(P=0.035)。男生显现阴茎或睾丸发育、变声等青春发育特征的一组左右手指长比均数均低于未显现特征组,且在13~14岁男性青少年中差异有统计学意义。未检出指长比与抑郁心理及攻击行为有统计学意义的关联。结论低2D∶4D指长比与13~14岁男生青春期发育关联显著。需进一步开展研究以探索其作为小年龄青少年出生前性激素测量指示指标的可能性,建议对双手的2D、4D指长均做测量。
[Abstract]:Objective to investigate the relationship between forefinger (2D), ring finger (4D) and adolescent development, depression and aggression, and to explore the effect of growth and development on healthy behavior and psychology. Methods A total of 182 students aged from 10 to 14 years old in a nine-year school in Shanghai were selected by cluster sampling to study their physical development, depression and aggressive behavior. The length of 2 D and 4 D fingers were measured by Vernier calipers. Results the mean value of 2D:4D finger length ratio of girls with right hand and left hand was higher than that of boys (left hand: 0.988 and 0.971; right hand: 0.996 and 0.981), the difference was statistically significant (t = 3.19, 3.32, P < 0.05). The association between the change of voice in male adolescents and the length of left 2D:4D low finger was found in 10 ~ 12-year-old (P0. 035). The mean ratio of finger length to finger length in the boys who showed penis or testicular development and changed tone was lower than that in the unmanifested group, and the difference was statistically significant among the male adolescents aged 13 to 14 years. The ratio of undetected finger length was significantly associated with depression and aggressive behavior. Conclusion low 2D:4D index length ratio is significantly associated with puberty development of 13-14-year-old boys. Further research is needed to explore the possibility of using it as an indicator of sex hormone measurement before birth in young adolescents. It is suggested that the length of 2DX 4D finger in both hands should be measured.
