摘　　要：目的研究婴儿母亲孕期增重对婴儿肥胖风险的影响。方法选择2010年9月至2011年9月在合肥市各医院分娩并在合肥市某区保健站参加保健体检的婴儿及其母亲作为研究对象，共785对。采用百分位数法按孕期增重进行分组：孕期增重过多组126对；孕期增重适中组542对；孕期增重过少组117对。收集婴儿母亲的一般人口统计学信息，同时在婴儿满42d及3、6、9、12个月体检时，测量其身长、体重，计算Z分值，分析比较不同组别相关z分值的差异，计算不同孕期增重对婴儿肥胖的RR值。结果在42d及3、6、9、12个月时，孕期增重过多组婴儿年龄别体重的Z分值分别为0．23±0．93、0．25±1．03、0．23±0．99、0．28±1．09、0．26±1．14，均高于相应年龄的孕期增重适中组（分别为-0．04±1．02、-0．07±0．99、-0．05±0．98、-0．06±0．97、-0．07±0．95），差异均有统计学意义（P值均〈0．05）；孕期增重过多组婴儿在9个月[（18．01±0．15）kg／m2]、12个月时BMI[（17．66±0．15）kg／m2]高于适中组[分别为（17．63±0．13）、（17．22±0．15）kg／m2]，差异均有统计学意义（P值均〈0．05）；3组婴儿年龄别身长的Z分值差异无统计学意义（P〉0．05）。相对于孕期增重适中组，孕期增重过多组婴儿肥胖的RR（95％CI）值为1．86（1．14—3．03）。结论孕期增重过多增加婴儿肥胖的风险。Objective To study the impact of maternal weight gain during pregnancy on the risk of infant obesity within 1 year old. Methods A total of 785 infants who were born in Hefei and participated children medical care in one district health center and their mothers were chosen as the research subjects from September 2010 to September 2011. Three groups were classified by weight gain during pregnancy according to the percentiles：excessive pregnancy weight gain group of 126 pairs ,adequate pregnancy weight gain group of 542 pairs and inadequate pregnancy weight gain group of 117 pairs. Mother＇s general demographic information was collected. The height and weight were measured when the infant was 42 days ,3, 6,9,and 12 months of physical examination. Z score was calculated. The differences of Z score in different groups were compared and the RR values of different weight gain during pregnancy on infant obesity were computed. Results The weight-for-age Z score （WAZ） of infant at 42 days 3,6,9 and 12 months in excessive pregnancy weight gain group were 0. 23 ± 0. 93,0. 25 ±1.03,0. 23 ± 0. 99,0. 28 ± 1.09,0. 26 ± 1.14,respectively, all higher than that of the corresponding age in adequate pregnancy weight gain group （ -0. 04 ± 1.02, - 0.07 ± 0. 99, - 0. 05 ± 0. 98, - 0. 06 ± 0. 97, - 0. 07 ± 0. 95, respectively） . The differences were statistically significant （ all P values 〈 0. 05 ）. In excessive pregnancy weight gain group, infant body mass index（BMI） at 9 months （（18.01 ± 0.15） kg/m2） and 12 months（（17.66 ± 0. 15 ）kg/m2 ） were higher than that of adequate pregnancy weight gain group（ （ 17.63± 0. 13 ）and（ 17.22± 0. 15 ）kg/m2 ,respectively） . The differences were statistically significant （all P values 〈 0. 05 ）. Differences of infant Height-for-age Z score（HAZ） among three groups were not statistically significant （all P values 〉 0. 05 ）. Compared to adequate pregnancy weight gain group,RR （95% CI） value of infant obesity in excessive pre
