The nutritional status among children under 60 months year-old after one year of the Earthquake in Wenchuan

Abstract

To evaluate the effects of Wenchuan Earthquake on the nutritional status, growth, and the prevalence nutritional anemia, vitamin A deficiency (VAD) and vitamin D deficiency among children under 60 months old living in the disaster areas. A nutritional survey was conducted in April 2009. The survey recruited 466 under 60 months old children, including 162 children aged 0 months old and 304 children aged 24 - 59 months old. The children's growth status, prevalence of anemia, and the iron deficiency prevalence, vitamin A, D, B(12), folic acid status were measured. The study findings were compared to the results from 2002 Chinese Nutritional and Health Survey. The exclusive breast milk feeding rate among infants under 6-months was 58.8% (30/51). Among the 0 - 23 months old children, only 10.7% (16/150) got breast feeding within one hour after delivery. Ninety-two per cent (149/162) 0 - 23 months old children never received any nutrient supplements. The average cereals and roots intakes of the 24 - 59 months old children living in the disaster area were (267.2 ± 154.3) g/d, higher than the result of rural children average (178.75 g/d) of 2002 National Nutrition and Health Survey (u = 9.995, P < 0.01). The average intakes of vegetables, aquatic products, meat and poultries were (63.6 ± 56.7), (2.6 ± 7.9), (19.4 ± 24.0) g/d, respectively, significantly lower than 2002 results 135.05, 8.82 and 32.23 g/d (u = 21.971, 13.728 and 9.321, P < 0.01). Fruits, dairy products and legumes intakes were (102.2 ± 110.8), (65.2 ± 123.8) and (20.5 ± 29.0) g/d, respectively, higher than 2002 results (32.81, 2.87 and 6.50 g/d; u = 10.919, 8.778 and 8.417, P < 0.01). The prevalence of vitamin A deficiency and marginal deficiency was 15.4% (29/188) and 30.3% (57/188), respectively. The sum of vitamin D deficiency and insufficiency was 92.0% (183/199). The prevalence of anemia of the 0-months old children and 24 - 59 months old children was 47.5% (77/162) and 21.5% (60/279), respectively. The prevalence of iron and zinc deficiencies was 45.7% (86/188) and 65.5% (127/197). The prevalence of stunt was 13.6% (38/279) among the 24 - 59 months old children. The results indicated that the dietary structure of the children living in the disaster area was not ideal. Although, the intakes of energy and protein supporting foods could meet the requirements, but the dietary lacks of meats, poultries, dairy products, legume products, aquatic products and vegetables. The vitamin A, vitamin D deficiency, iron and zinc deficiencies are of a high prevalence in the disaster area.
