Low anemia prevalence in school-aged children in Bangalore, South India: possible effect of school health initiatives.

OBJECTIVE: Anemia is a serious public health problem in Indian school children. Since 2003, simple health intervention programs such as antihelminthic treatment and vitamin A supplementation have been implemented in primary schools in the Bangalore region, Karnataka, India. This study examines the prevalence of anemia in school children who are beneficiaries of this program. DESIGN: Cross-sectional survey. SETTING: Bangalore district, South India. SUBJECTS: A total of 2,030 boys and girls, aged 5-15 years, attending schools in the Bangalore district. INTERVENTIONS: School-based, twice yearly intervention: deworming (albendazole 400 mg, single oral dose) and vitamin A supplementation (200,000 IU, single oral dose). MAIN OUTCOME MEASURES: Anemia prevalence based on measure of blood hemoglobin (Hb). RESULTS: Mean age and blood Hb concentration of all children were 9.5+/-2.6 years and 12.6+/-1.1 g/dl (range 5.6-16.7), respectively. The overall anemia prevalence in this group was 13.6%. Anemia prevalence was lower in boys than girls (12.0%; n=1037 vs 15.3%; n=993 respectively, P<0.05). There was no significant difference in anemia prevalence between children in urban and rural locations (14.6 and 12.3%, respectively). CONCLUSIONS: The current low anemia prevalence in Bangalore could be due to the impact of school-based intervention programs that have been in place since 2003. The beneficial interactions of deworming and vitamin A supplementation could have widespread implications for current preventive public health initiatives. There is now need for the development of clear policy guidelines based on these simple and integrated interventions.

Are we increasing serious maternal morbidity by postponing termination of pregnancy in severe pre-eclampsia/eclampsia?

The objective of this study was to evaluate the impact of admission--delivery interval on maternal morbidity in patients with severe pre-eclampsia/eclampsia. This was a retrospective study, which involved review of case sheets of 188 women (admitted to St John's Medical College Hospital during the year 2000--2001 with the above diagnosis). The incidence of severe pre-eclampsia and eclampsia was 5.18% (188/3,627) with 119 primigravida and 69 multigravida. The incidence of serious maternal complications in the post partum period was 17% (11/68) in the category of women who delivered within 12 hours of admission compared with 40.6% (28/69) in the 12--48-h category and 60.8% (31/51) in the>48-h category. The incidence of serious maternal complications in the subset with HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome was 33.4% (7/21) in the12-h. We concluded that termination of pregnancy within 12 hours of admission in severe pre-eclampsia/eclampsia especially in patients with HELLP syndrome helps to prevent avoidable serious maternal morbidity.
