標題: | HEIGHT AND WEIGHT CHANGE ACROSS MENARCHE OF SCHOOLGIRLS WITH EARLY MENARCHE | 作者: | CHANG, SHU-HUI | 公開日期: | 2000 | 卷: | v.154 | 起(迄)頁: | 880-884 | 來源出版物: | ARCHIVES OF PEDIATRICS AND ADOLESCENT MEDICINE | 摘要: | Objective To describe growth before and after menarche. Design Nine hundred five fourth grade school girls were identified as a closed cohort from the first semester of 1993 for the observational study of the onset of menarche and its predictive factors. Settings Eight elementary schools in Taipei City and Taipei County, Taiwan. Main Outcome Measures Data were collected from self-administered questionnaires and school records. Height and weight were measured in September, January, February, and June, or only in September and February of each year. Results All subjects remained in the cohort until sixth grade, 410 of whom had their first menstruation before graduating from elementary school. Height, weight, and body mass index (calculated as weight in kilograms divided by the square of height in meters) at each time point were plotted against 2 time scales: chronological age and time from the onset of menarche. Growth velocity of height and weight across the onset of menarche was assessed with slope change using the mixed-effect model analysis. Conclusions The results support the hypothesis that height velocity reaches a peak 1 year before menarche but height velocity stopped increasing within 1 year after menarche. The change in weight velocity reveals no obvious growth spurt at age of menarcheal onset. |
