Abstract

Based on the data from China Health and Nutrition Survey (CHNS), 840 girls aged 6-15 years who had information about menarche and participated in dietary survey at least once within 1-5 years before onset of menarche between 1989 and 2015 were included in the study. The median age at baseline of the 840 participants was 10 (9, 11) years. The median age at menarche of the participants was 13 (12, 14) years. After adjusting for the age of birth, place of residence, body mass index Z-score, physical activity level and annual household income per capita, the average age of menarche was advanced by 0.036 (95%: -0.068, -0.004) years for every 10 g increase in daily fat intake before menarche. The average age at menarche was 0.008 (95%: -0.014, -0.001) years earlier for every 1% increase in the daily energy supply ratio of fat before menarche.

摘要

基于中国健康与营养调查（CHNS）的数据，本研究纳入了840名6至15岁的女孩，她们有月经初潮信息，且在1989年至2015年月经初潮前1至5年内至少参加过一次饮食调查。840名参与者的基线中位年龄为10（9，11）岁。参与者月经初潮的中位年龄为13（12，14）岁。在调整了出生年龄、居住地点、体重指数Z评分、身体活动水平和家庭人均年收入后，月经初潮前每日脂肪摄入量每增加10克，月经初潮的平均年龄提前0.036（95%：-0.068，-0.004）岁。月经初潮前每日脂肪能量供应比例每增加1%，月经初潮的平均年龄提前0.008（95%：-0.014，-0.001）岁。
