Objectives: The objective of the study was to evaluate the critical body mass index and critical percent body fat of East Asian immigrants with normal menstrual cycles.
Methods: The subjects included 1,710 east Asian women (Vietnamese and Cambodians, etc.) who immigrated to Korea for marriage. Their menstrual status was examined by questionnaires and interviews. The age, body mass index and waist-hip ratio were calculated and the percentage of body fat was measured using In body 230.
Results:The mean age was 23.7±4.7 years. In 1,065 east Asian immigrants with normal menstrual cycles, the mean body mass index was 20.99±2.56 kg/m2. The 5th, 10th, 90th and 95th percentiles of the body mass index were 17.35 kg/m2, 17.99 kg/m2, 24.57 kg/m2, and 25.94 kg/m2, respectively. The mean waist-hip ratio was 0.824±0.051. The 5th, 10th, 90th, and 95th percentile of the waist-hip ratio were 0.744, 0.759, 0.892, and 0.910. The mean percent body fat was 29.57±6.15%. The 5th, 10th, 90th and 95th percentiles of body fat were 19.28%, 21.75%, 36.70%, and 39.00%, respectively.
Conclusion: Our results suggest that both body mass index and percent body fat were significantly associated with menstruation, but the critical percent body fat for normal menstruation was lower in the east Asian immigrants in Korea.
