摘要
目的调查早产产妇产后膳食情况及与母乳营养成分的相关性。方法早产产妇在产后2周和6周、足月产妇在产后6周时分别进行24 h膳食调查,各留取其后一日的母乳样本,将膳食营养素摄入量与母乳营养成分作相关分析。结果早产产妇产后2周膳食摄入调查表共回收30份,产后6周16份,足月产妇产后6周膳食调查表31份。早产产妇产后6周宏量营养素摄入与足月产妇比较差异无统计学意义(P>0.05);体型正常产妇与超重肥胖产妇母乳营养成分差异无统计学意义(P>0.05)。早产产妇产后蛋白质、脂肪、碳水化合物摄入与其母乳中蛋白质、脂肪和碳水化合物含量无显著相关(P>0.05)。结论在蛋白质-能量营养状况正常的早产产妇,短期内蛋白质、脂肪、碳水化合物摄入与其母乳成分未发现明确相关性。
Objective To evaluate dietary intakes of mothers of premature infants and to explore its possible associations with macronutrients and energy in breast milk .Methods A 24-hour dietary survey was conducted in mothers of premature infants at 2 and 6 weeks postpartum , and in mothers of term infants at 6 weeks postpartum . Breast milk samples were collected the day following the survey .The possible correlation between the macronutrients （including protein, fat, carbohydrate, and dry matter） and energy in the milk samples and dietary intakes was analyzed.Results Totally, 46 questionnaires were collected from mothers of premature infants （30 at 2 weeks, 16 at 6 weeks postpartum ） and 31 from mothers of term infants at 6 weeks postpartum .At 6 weeks postpartum , general dietary intakes showed no significant difference between mothers of premature infants and those of term infants （P〉0.05）.There was no significant difference in milk macronutrients and energy between normal body mass index mothers and overweight/obese mothers （P〉0.05）.No association was found between the dietary protein , fat, carbohydrate intakes and the levels of these macronutrients in the breast milk in mothers of premature infants （ P〉0.05）.Conclusions There may be no association between the near-term dietary intakes and the macronutrients and energy in the breast milk in mothers of premature infants who are in normal nutritional status .
