RESUMO
BACKGROUND: Iron-deficiency anemia among school-aged children is widespread in India. The efficacy of micronutrient and iron fortified school-served meals in reducing iron deficiency anemia has been demonstrated in randomized controlled trials in other parts of the globe. The current study evaluates its effectiveness in real-world Indian settings. METHODS: Mid-day-Meal (MDM) programme provides free lunch to students of grades 1 to 8 in all public-funded Indian schools. An implementation research project fortified MDM of all public schools of 4 out of 8 sub-districts ("blocks") of Dhenkanal district of Odisha state with fortified rice kernel (FRK). All the schools of the other 4 blocks fortified with micronutrient powders (MNP)-both FRK and MNP containing equal amounts of supplementary iron and other micronutrients. Schools of 4 matched blocks of neighboring nonimplementing Angul district served as control. Cross-sectional representative samples of students were drawn from the 3 arms, before and after intervention (n = 1764 and n = 1640 respectively). Pre-post changes in anemia prevalence and hemoglobin levels were estimated in the sampled children using difference-in-difference analysis after controlling for inter-arm differences in socioeconomic status, and iron and deworming tablet consumptions. RESULTS: Factoring in pre-post changes in control and adjusting for potential confounders, the proportion of children without anemia and mean hemoglobin improved by 1.93 (1.38, 2.24, P < .001) times and 0.24 (-0.03, 0.51, P = .083) g/dL in MNP; and 1.63 (1.18, 2.24, P = .002) times and 0.18 (-0.09, 0.45, P = .198) g/dL in FRK arms. CONCLUSIONS: Fortified MDM could effectively improve anemia status among Indian school-aged children under real-world conditions.

BACKGROUND: An outbreak of measles was reported from a slum, UT, Chandigarh in April 2003. Similar outbreak was also reported in less than three years from the same and adjoining areas. The present study was conducted to investigate and assess various epidemiological features associated with measles outbreak. MATERIAL AND METHODS: Three cases of measles were admitted in Dept. of Paediatrics, Govt. Medical College & Hospital, Chandigarh and were reported to the Dept. of Community Medicine for an outbreak investigation. A trained team investigated the slum having a population of 25,000 and studied various features associated with epidemic between the period of April 22 to May 10, 2003. RESULTS: The study covered 484 houses having 1130 children. Among the children who developed measles 32.76% were vaccinated ones. In them attack rate was 3%. Attack rate in vaccinated children went on increasing as age increased. An overall attack rate of 5.13% (Peak incidence 6% in 1-4 years age group) was recorded. Among measles cases, one-fifth had post measles complications. As much as 32.76% children with measles had received measles vaccination in the past. Therefore something more than immunization by single dose of vaccine is required. Measles was reported to be higher amongst the children without Vitamin A supplementation (P < 0.001). CONCLUSION: There is need to store vaccine properly and to strengthen routine immunization coverage, Vitamin A supplementation and health infrastructure in underprivileged population. Serological studies among vaccinated children against measles should be undertaken to explore the possibility of second dose of measles in older children.
