简要总结
Iron deficiency is estimated to affect about one fifth of the world's population, and women and children are among the most severely affected. Evidence is mounting that iron deficiency anemia adversely affects brain development with measurable effects on children's behavior, motor development and cognition. In Hisar district of Haryana state, north- India, 58% of school age children (6-10 years) are anemic, 49 % are iron deficient whereas 40 % have been found to be anemic due to iron deficiency. Iron bioavailability calculated using algorithms in regional diets ranged from 3.2 to 4.6 percent. Mungbean (Vigna radiata L.) is the third most important legume crop of India. It is a high potential legume crop with 4-8 mg of iron and known as a nutritious and healthy legume. Ascorbic acid is a potent enhancer of iron absorption in humans which can counteract the inhibitory effect of phytic acid and polyphenols. Guava is a popular and easily available fruit for this community having 200- 300 mg/100g of ascorbic acid. We will conduct a randomised controlled trial in school age children (6-10 years) in Haryana state of India, to determine the efficacy of local vitamin-C rich fruit guava with mungbean based meal on iron status of rural Indian children.
Objective: To assess the effect of mungbean based test meal on iron status (as body iron stores, defined and calculated by the ratio of serum ferritin and serum transferrin receptor) of school age children (6-10 years) with and without the consumption of guava, a vitamin C rich fruit, in a school feeding program for seven months.
Study population: Three hundred school children aged between 6-10 years will be recruited from two government school of Mangali village situated in Hisar district of Haryana state.
Study design: This intervention study will be carried out in a randomized controlled design. Main study parameters/endpoints: Primary outcome will be the measurement of body iron stores (mg/kg of body weight) based on the ratio of serum transferrin receptor to serum ferritin.
详细描述
Primary Objective To measure the effect of mungbean based test meal on iron status (defined by body iron stores, calculated as the ratio of ferritin and serum transferrin receptor) of school age children (6-10 years) with and without the consumption of guava, a vitamin C rich fruit, distributing in school feeding program for seven months.
Three weeks before the trial available children (6-10 years) in selected schools will be screened for eligibility of the study on the basis of medical health questionnaire. Deworming will be done at least 20 days before the start the feeding trial with a single dose of Albendazole (400 mg), that will be given again after three months. These 300 children will be assigned to three groups (100 children each group). Group-1 will be served with the normal school feeding program (SFP) meal (see annexure-1) and this group will also serve as control group for the study. Group-2 will be served with mungbean test meal (see annexure-2) and group-3 will be served with guava fruit in addition of mungbean test meal. Meals to all children will be provided for six days in a week up to seven months. All meals will be served at mid morning (11.00 am to 11.30 am). Effect of intervention will be assessed in terms of iron status of children.
This study will be carried out in two government schools of Mangali village belong to Hisar-1 block of Hisar district Haryana state with the close supervision of Chaudhary Charan Singh Haryana Agriculture University, Hisar.
Children having severe anemia (Hb <7.0 g/dl) will be excluded from the trial and referred for medical treatment.
Subjects will be recruited that comply with the following criteria:
