目的:探讨孕期营养对孕期增重的影响。方法:以问卷调查的形式对714例乌鲁木齐维(吾尔)、汉族孕产妇的膳食摄入与体重增长情况进行统计学分析。结果:乌鲁木齐市维、汉族孕产妇孕前BMI为(21.63±3.69)kg/m2,孕期增重(16.89±5.82)kg;维、汉族妇女孕前BMI、孕期增重比较差异均无统计学意义(P>0.05);维、汉族孕产妇孕晚期钠摄入过高,是推荐供给量的127%和160%,而钙、铁、锌、碘、叶酸、维生素C的摄入严重不足,均低于推荐供给量的70%;热能构成比中,碳水化合物供热过低,脂类供热过高。结论:乌鲁木齐维、汉族孕产妇孕期增重过多,与孕期膳食结构不合理有关。
Objective: To investigate the effect of prenatal nutrition on weight gain during pregnancy. Methods: The dietary intake and weight gain of 714 Urumqi (Uygur) and Han pregnant women were statistically analyzed by questionnaire. Results: Before pregnancy, the BMI of pregnant women in Uygur and Han nationality in Urumqi was (21.63 ± 3.69) kg / m2, and the weight gain during pregnancy was (16.89 ± 5.82) kg. There was no significant difference in the BMI before pregnancy between Uygur and Han nationality women > 0.05). The pregnant women in Victoria and Han nationality in the third trimester of pregnancy had high sodium intake, which was 127% and 160% of the recommended supply, while the intake of calcium, iron, zinc, iodine, folic acid and vitamin C was seriously less than Recommended supply of 70%; heat composition ratio, carbohydrate heating is too low, fat heating too high. CONCLUSION: Excessive weight of pregnant women in Urumqi-Han and Han nationality during pregnancy is unrelated to the unreasonable dietary structure during pregnancy.
