摘  要:目的了解2010年拉萨市农村0~35月龄藏族儿童的生长发育及营养不良状况。方法采用多阶段整群抽样法,抽取拉萨市达孜县和曲水县的6个乡镇0—35月龄婴幼儿640名,通过测查其身长和体重获得营养状况的资料,按照2006年WHO推荐的新标准,利用WHOAnthro2005软件,采用标准统计量检定法(Z值法)估计儿童群体的营养状况,并比较婴幼儿的年龄别体重Z值(WAZ)、年龄别身长Z值(HAZ)和身长别体重z值(WHZ)。结果拉萨市农村18—35月龄婴幼儿身长比国家标准平均低3.0em;6~11、12~17月龄男性婴幼儿体重[(8.84±1.23)、(10.20±1.08)kg]、身长[(70.45±4.46)、(76.73±4.78)cm]均高于女性[体重分别为(8.42±1.30)、(9.59±1.26)kg,身长分别为(67.61±3.98)、(74.25±4.50)em](P值均〈0.05)。调查对象WAZ、HAZ分别为-0.17±1.11和-1.11±1.46,WAZ、WHZ随月龄的增加呈下降趋势(P值均〈0.05),18~23月龄婴幼儿的HAZ(-1.51±1.24)与0-5、6~11、12—17月龄婴幼儿(HAZ值分别为-0.75±1.50、-0.83±1.72、-1.07±1.55)差异均有统计学意义(P值均〈0.05),18~23月龄婴幼儿HAZ与24~29、30—35月龄婴幼儿(HAZ值分别为-1.41±1.25、-1.24±1.05)差异均无统计学意义(P值均〉0.05)。调查地区0~35月龄婴幼儿生长迟缓率、低体重率和消瘦率分别为24.6%(155/630)、5.4%(33/616)和1.0%(6/608);男童生长迟缓率(29.4%,99/337)和低体重率(7.3%,24/329)均高于女童[19.1%(56/293)、3.1%(9/287)];分月龄分析发现,18~23、24~29月龄婴幼儿生长迟缓率较高,分别为35.0%(36/103)和29.1%(25/86)。结论拉萨市农村3岁以下儿童生长发育不佳,儿童营养不良状况不容忽视且存在性别和月龄差异。Objective To understand the growth and malnutrition status of Tibetan children aged 0 to 35 months in rural Lhasa in 2010. Methods Cross-sectional study and multistage sampling design were used to randomly select sampling units. A total of 640 children were studied. Height and weight were measured and nutritional status was evaluated with WHO reference in 2006 using Z-scores. Z-scores of weight-for-age(WAZ) , Z-scores of height-for-age ( HAZ ) and Z-scores of weight-for-height ( WHZ ) were analyzed. Results At the age of 18 -35 months, the children in rural Lhasa were 3.0 cm shorter as compared to the China national length reference. At the age of 6 - 11, 12 - 17 months, weight( (8.84 ± 1.23) and (10.20 ±1.08) kg) and length((70.45 ±4.46) and (76.73 ±4.78) cm) of boys were significantly higher than girls ( weight : ( 8.42 ± 1.30 ) and ( 9.59 ± 1.26 ) kg ; length : ( 67.61 ± 3.98 ) and (74.25 ±4.50) em) (all P values 〈0.05). WAZ and HAZ were -0. 17 ± 1.11 and - 1.11 ± 1.46, respectively. The HAZ of 18 -23 months children( - 1.51 ± 1.24) was significantly different from the HAZ of 0 -5,6 - 11,12 - 17 months ehildren(HAZ: -0.75 ± 1.50, -0.83 ± 1.72, - 1.07 ± 1.55,respectively) ( all P values 〈 0. 05 ), comparison with the HAZ of 24 - 29,30 - 35 months children ( HAZ : - 1.41 ± 1.25, - 1.24 ± 1.05 ), the results showed that there were no signifieant difference( all P values 〉 0. 05), HAZ of 18 -23 months children was the lowest. The prevalenee of stunting, underweight, and wasting were 24. 6% ( 155/630), 5.4% (33/616) and 1.0% (6/608), respectively. The malnutrition of boys was more serious than that of girls, the stunting of 18 - 23 and 24 - 29 months children had reached 35.0% ( 36/103 ) and 29. 1% ( 25/86 ), respectively. Conclusion The growth and development status of children in rural Lhasa under 3 years old was poor, and the malnutrition of local children should not be ignored with v
