摘要
目的探讨产后饮食与体内雌激素水平的相关性。方法筛选初产妇,单胎足月,无其他疾病的女性发放知情同意书,进行问卷调查,包括产妇基本情况、膳食频率,并采用ELISA酶联免疫法检测女性产后3个月时体内血清雌二醇(E2)水平。分析半定量膳食问卷,结合中国居民平衡膳食宝塔及邬志薇食物平均营养素计算每日能量及宏量营养素摄入值,采用Pearson相关分析饮食与产后3个月时体内E2水平的相关性。结果产妇基本情况:产妇年龄均数约为29岁;体重指数(BMI)≥24 kg/m2的有51人,占总调查人数的48.11%;剖宫产率与自然分娩率分别占51.89%和48.11%;纯母乳喂养率达58.49%;产后3个月体内E2浓度的均数为83.32 pmol/L,催乳素(PRL)浓度均数为1 406.17 ng/L。总能量、脂肪、蛋白质、碳水化合物、膳食纤维与血清E2、PRL无相关性(P>0.05),总能量、脂肪、碳水化合物、膳食纤维与血清葡萄糖(GLU)、胆固醇(CHO)、甘油三酯(TG)、高密度脂蛋白(HDL)、低密度脂蛋白(LDL)、极低密度脂蛋白(VLDL)无相关性(P>0.05),仅蛋白质摄入量与CHO有相关性(P<0.05)。结论采用膳食半定量FFQ调查方法,ELISA检测血清E2含量,分析不同膳食总能量、宏量营养素、膳食总纤维摄入量与血清E2水平的相关性,未得出饮食与血清E2含量具有相关性的结论。
Objective To explore the correlation between postpartum diet and serum estrogen level. Methods The primiparous women（ single birth,full- term） without other diseases were investigated by a questionnaire based on the principle of informed consent,the survey contents included basic situations and dietary frequency,ELISA was used to detect serum estradiol levels at 3 months after delivery. Semi- quantitative dietary questionnaire was performed,combining with Chinese balanced diet guideline and food mean nutrients completed by WU Zhiwei,daily energy and macronutrient intake were calculated,Pearson correlation analysis was used to analyze the correlation between diet and estradiol level at 3 months after delivery. Results Maternal basic information： the mean age was 29 years old; 51 women were found with body mass index（ BMI） ≥24 kg / m^2,accounting for 48. 11%; the rates of cesarean section and spontaneous delivery were51. 89% and 48. 11%,respectively; the exclusive breastfeeding rate was 58. 49%; the mean levels of estradiol and prolactin at 3 months after delivery were 83. 32 pmol / L and 1 406. 17 ng / L,respectively. The total energy,lipid,protein,carbohydrate,and dietary fiber were not correlated with serum estradiol and prolactin（ P 〉0. 05）; the total energy,lipid,carbohydrate,and dietary fiber were not correlated with serum glucose,cholesterol,triglyceride,high- density lipoprotein,low- density lipoprotein,very low- density lipoprotein（ P〉 0. 05）;only protein intake was correlated with cholesterol（ P〈 0. 05）. Conclusion The conclusion of there is a correlation between diet and serum estradiol level is obtained by analyzing the correlation between different total dietary energy,total intakes of macronutrients,dietary fiber and serum estradiol level by dietary semi- quantitative food frequency questionnaire and detection of serum estradiol by ELISA.
