The aim of this study was to examine the relationship between indicators of risk of disordered eating, body image and varied menstrual cycle lengths. Altogether, 151 female athletes were invited from 16 sports and 70 female non-athletic controls were recruited from a university lecture class. The participants completed several surveys, including demographics, menstrual cycle history, physical activity, Eating Disorder Inventory (EDI) and the Three Factor Eating Questionnaire (TFEQ). Selected EDI subscales were summed to reflect eating disorder risk and body image. Menstrual cyclicity was based on self-reported cycle length for the last 6 months (normal cycles = 26-32 days, irregular cycles < or =26 or >32 days). Athletes overall had more irregular cycles (29.1%) than the non-athletes (15.7%) (P < 0.05). There were significant differences in scores for eating disorder risk, body dissatisfaction, drive for thinness, cognitive restraint (TFEQ) and disinhibition (TFEQ), only when athletes were divided based on menstrual cyclicity (i.e. irregularly cycling athletes had higher scores than athletes with normal menstrual cycle lengths). No differences in these scores were found between non-athletes with normal or irregular menstrual cycle lengths. In conclusion, irregularly short or long menstrual cycle length is associated with subtle indications of higher risk of disordered eating in female athletes. 相似文献

＂行为疏离者＂是领导者与下属因行为疏离而形成的对立关系状态。＂共同遭遇者＂是领导者与下属遭遇到共同状况从而同心同德、同舟共济的现象。学校发展共同体,是以教职工职业场域为基础,自愿为前提,＂信任、合作、分享、发展＂为核心精神,以追求成功人生为纽带,以促进教职工个体和整体以及学校发展为共同愿景,在互动协作的过程中形成的一种关系的连结。形成这种共同体需要转换领导者角色,从刚性的权力本位到柔性的人本位,建设信任、合作、互惠型的学校文化,就会积累丰厚的学校＂社会资本＂,就会和谐发展,就会具有强劲的凝聚力和最佳的创新活力。 相似文献
