   摘要
   目的：与健康青少年相比，患有哮喘的青少年遭受更多社会心理和生理的问题。体力活动(PA)可减少这些问题。本研究是评估哮喘青少年习惯性PA是否可随时间预测性改变社会心理结果(如焦虑和抑郁症状，生活质量，压力)和哮喘控制以及性别是否可缓和这些关系的首个观察性纵向研究。
   方法：2012年和2013年春天/夏天家访患有哮喘的青少年(N=253；基线年龄为10～14岁)。并让其完成评估他们习惯性PA、焦虑和抑郁症状、生活质量、知觉压力和哮喘控制的调查问卷。采用Mplus进行路径分析评估习惯性PA、社会心理结果和哮喘控制(体质指数、年龄和性别控制)间的纵向关系。采用多组分析，评估性别是否可缓和这些关系。
   结果：全组的路径分析显示习惯性PA随时间并不能预测改变社会心理结果或哮喘控制。多组分析显示性别可缓和习惯性PA与焦虑和抑郁间的关系。习惯性PA随时间仅可显著预测性减少女孩而非男孩的焦虑和抑郁症状。
   结论：哮喘女孩中习惯性PA的增加可能减少其焦虑和抑郁症状。

ABSTRACT
OBJECTIVE：Adolescents with asthma experience more psychosocial and physiological problems compared to their healthy peers. Physical activity (PA) might decrease these problems. The current study was the first observational longitudinal study to examine whether habitual PA could predict changes in psychosocial outcomes (i.e., symptoms of anxiety and depression, quality of life, stress) and asthma control over time in adolescents with asthma and whether gender moderated these relationships.
METHODS ：Adolescents with asthma (N = 253; aged 10-14 at baseline) were visited at home in the spring/summer of 2012 and 2013. They completed questionnaires assessing their habitual PA, symptoms of anxiety and depression, quality of life, perceived stress, and asthma control. Path analyses using Mplus were conducted to examine longitudinal relationships among habitual PA, psychosocial outcomes, and asthma control (controlled for body mass index, age, and gender). Using multi-group analyses, we examined whether gender moderated these relationships.
RESULTS ：Path analyses in the total group showed that habitual PA did not predict changes in psychosocial outcomes or asthma control over time. Multi-group analyses showed that gender moderated the relation of habitual PA with anxiety and depression. Habitual PA only significantly predicted a decrease in anxiety and depression over time for girls but not for boys.
CONCLUSIONS：Increasing habitual PA in girls with asthma might decrease their symptoms of anxiety and depression.
