Menstrual function was assessed comparatively in different categories of 155 Nigerian athletes, aged 13-19 years, and 135 nonathletes, aged 12-18 years, who answered questionnaires and were interviewed. Menstruation was more regular and normal in the nonathletes (44%) than the athletes (21%). Although both groups generally had similar patterns of menstrual dysfunction, secondary amenorrhea or oligomenorrhea (O/A) was more prevalent in the athletes (25%) than the nonathletes (10%). Among the athletes, only the distance runners were significantly lighter and leaner than nonathletes and athletes of other sports (P less than 0.05). Regardless of sports activity, oligomenorrheic subjects had substantially lower body weight relative to stature and were leaner than subjects of the other menstrual categories. In the oligomenorrheic group, a greater proportion of the athletes (59%) and nonathletes (57%) had lean body mass values below the 41st percentile. The premenarche-trained athletes (48%) reported a higher incidence of menstrual cycle irregularities than the athletes who began training after the menarche. Results support the role of body composition-related factors in the etiology of exercise-associated O/A.
对155名年龄在13至19岁的尼日利亚运动员和135名年龄在12至18岁的非运动员进行了月经功能的比较评估，这些人填写了问卷并接受了访谈。非运动员的月经规律和正常情况（44%）高于运动员（21%）。尽管两组的月经功能障碍模式总体相似，但继发性闭经或月经过少（O/A）在运动员中（25%）比非运动员中（10%）更为普遍。在运动员中，只有长跑运动员比非运动员和其他运动项目的运动员明显更轻、更瘦（P小于0.05）。无论体育活动如何，月经过少的受试者相对于身高体重明显更低，且比其他月经类别的受试者更瘦。在月经过少组中，更大比例的运动员（59%）和非运动员（57%）的瘦体重值低于第41百分位数。月经初潮前开始训练的运动员（48%）报告的月经周期不规律发生率高于月经初潮后开始训练的运动员。结果支持了身体成分相关因素在运动相关O/A病因中的作用。
