Abstract
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) cm) (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 children (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 significant difference (all P values > 0.05), HAZ of 18 - 23 months children was the lowest. The prevalence 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 variations by gender and months of age.
