          Abstract

          Objective To explore the relationship between premenarchal dietary carbohydrate and dietary fiber intakes and age at menarche in Chinese girls.

          Methods Based on dietary and menarcheal information on 750 girls from the Chinese Health and Nutrition Survey, multivariate linear regression models and logistic models were used to analyze the influence of dietary carbohydrate and dietary fiber intakes before menarche onset and age at menarche. Carbohydrate intake was replaced by engergg ratio carbohydrate for a sensitivity analysis.

          Results Adjusting for residence, per capita household income, body mass index standard deviation score, and energy intake, higher intake and higher energy ratio of carbohydrate were associated with later age at menarche ( P <0.01). Compared to girls at the lowest tertile of carbohydrate intake level, those at the highest tertile had a 0.35 years (2.8%) delay in age at menarche, while 55% decreased [ OR(95%CI) = 0.45(0.30–0.69)]. Dietary fiber intake was not associated with age at menarche in any model ( P>0.2).

          Conclusion Girls with higher premenarcheal carbohydrate intake experienced menarche later, while dietary fiber intake was not associated with age at menarche.

          Abstract

          【摘要】 目的 探索中国女童初潮前碳水化合物及膳食纤维摄人与初潮年龄的关系, 为预防儿童性早熟提供有效干预措 施。 方法 由中国健康与营养调査数据库获取750名中国女童初潮前膳食信息及初潮年龄, 建立多元线性回归及逻辑回 归模型, 分析女童初潮前膳食碳水化合物及膳食纤维摄人量对初潮年龄的影响, 以碳水化合物供能比替代碳水化合物摄人 量进行敏感性分析。 结果 调整居住地、家庭人均年收人、体质量指数标准差评分、膳食总能量摄人后, 初潮前较髙碳水化 合物摄人量和碳水化合物供能比推迟初潮发生 ( P值均<0.01);碳水化合物摄人量在最髙三分位数组的女童初潮年龄较最 低三分位组推迟0.35岁 (2.8%)。碳水化合物供能比在最髙三分位数女童初潮早发风险较最低三分位组降低55%[ OR值 ( OR值95% CI)= 0.45(0.30~0.69)]。在所有模型中, 膳食纤维摄人量与初潮年龄间相关无统计学意义 ( P>0.2)。 结论 初潮前较髙膳食碳水化合物摄人可能推迟中国女童初潮发生, 而膳食纤维摄人与初潮年龄无关。
