摘要:
目的 探讨以两种不同发育指标为参照时,青春发动时相提前与问题行为的关系.方法 选取北京市3003名6~11岁小学在校女生,选用Tanner分期法,根据月经初潮和阴毛发育水平对女生的生理发育进行评估,Achenbach儿童行为量表评估问题行为.结果 以月经初潮和阴毛发育水平为参照时,青春发动时相提前的检出率分别为11.2%和3.4%;两种发动时相评估结果的相关性无统计学意义(r=0.04, P=0.06).月经初潮提前组的退缩问题(Z=-2.23, P=0.03)和躯体主诉问题(Z=-2.64, P=0.01)得分高于适中组.阴毛发育提前组的退缩问题(X2=2.53, P=0.03)高于适中组,社交问题(X2=2.71, P=0.02)、攻击性问题(X2=2.50, P=0.04)和问题行为总分(X2=2.64, P=0.03)高于延后组.结论 以月经初潮和阴毛发育水平为参照时,青春发动时相提前的检出率不同,与发动时相提前有关的问题行为也不同.与月经初潮提前相比,阴毛发育提前的女生可能在较多项目上表现出问题行为增多.%Objective To explore the relationships between advanced puberty timing and frequencies of problem behaviors using two different indexes of pubertal development as cut-off standards. Methods A total of 3003 primary school girls aged 6~11 in Beijing were recruited in the study. Parent-assessed Tanner staging according to the menarche and pubic hair development level and the Achenbach Child Behavior Checklist were applied. Results When timing of menarche and pubic hair development stage were used as reference, the detection rate of girls with advanced puberty timing was 11.2% (337/3003) and 3.4% (101/3003), respectively. The scores of withdrawal problem (Z=-2.23, P=0.03) and physical problem (Z=-2.64, P=0.01) were higher in the advanced menarche group than in the moderate group. The scores of withdrawal behavior problem were higher in the advanced pubic hair development group than in the moderate group (X2=2.53, P=0.03). Scores of social problem (X2=2.71, P=0.02), aggression problem (X2=2.50, P=0.04), total score of problem behavior (X2=2.64, P=0.03) were also higher in the advanced pubic hair development group than in the delayed group. The correlation between the pubertal timing results based on the two different cut-off standards was not significant (r=0.04, P=0.06). Conclusion T he detection rate of girls with advanced puberty timing are different using the two different cut-off standards. The prominent problem behaviors in the advanced group are also different. Compared with girls with advanced menarche, girls with advanced pubic hair development may have more prominent problem behaviors than those with moderate development.
