RESUMEN
BACKGROUND: Anemia control has hitherto been through prophylaxis with weekly iron folic acid (IFA) in Indian women of reproductive age (WRA). Recently, a more precise approach has been proposed, that uses a 'screen and treat with IFA' approach for anemic WRA, combined with continued prophylactic IFA in non-anemic WRA. The efficacy of this approach was assessed in Indian WRA, along with changes in iron status biomarkers. METHODS: Young WRA (n = 470), aged 17-21 y, were screened for their venous blood hemoglobin (Hb) and treated with IFA for 90 days according to their grade of anemia, or if non-anemic, administered prophylactic IFA, per Indian policy guidelines, and then followed-up for an additional 9-months. Their Hb, plasma ferritin (PF), transferrin receptor, hepcidin and C-reactive protein concentrations were measured at baseline, during treatment and further follow-up. Anemia was diagnosed using Hb (<12 g/dL) and iron deficiency (ID) using PF (<15 µg/L) cut-offs after adjustment for inflammation. Co-existence of anemia and ID was labelled iron deficiency anemia (IDA). RESULTS: At baseline, in the whole group anemia, ID and IDA prevalence was 69.6%, 68.7% and 62.4%, respectively. At 90 days, IFA treatment or prophylaxis significantly reduced anemia by 40 percentage points (pp), from 69.6% at baseline to 29.8%; ID by 47.3 pp, and IDA by 48 pp. Moreover, significant treatment effects persisted at 365 days of follow-up. CONCLUSION: The 'screen and treat with IFA' approach is efficacious in reducing the prevalence of anemia in general among WRA, with persistent and significant effects after 9 months of follow-up.

OBJECTIVE: To compare the acceptability of a locally produced ready-to-use therapeutic food (L-RUTF) with the standard ready-to-use therapeutic food (S-RUTF). METHODS: It was a single-center, randomized, double-blind, two-way crossover study. The participants were 6-59-mo-old children residing in an urban slum, with weight-for-height z score (WHZ) < -2SD. The study had two intervention periods of feeding with two types of RUTF- L-RUTF and S-RUTF-for a period of 24 h, separated by a wash-out period of 7 d. The outcome measures were the acceptability measured as consumption of more than two-thirds of the total calories offered (150 kcal/kg/24 h) and the degree of liking of the food measured by organoleptic evaluation. RESULT: Both types of RUTF did not qualify as acceptable. L-RUTF was preferred over S-RUTF in organoleptic evaluation. CONCLUSION: The study suggests that RUTF products are not suitable for use as a single therapeutic food during nutrition rehabilitation of children with acute malnutrition. The study was registered in the clinical registry of India; Reg. No: CTRI/2018/04/012967.

BACKGROUND: Anemia control programs in India focus mainly on the measurement of hemoglobin in response to iron-folic acid supplementation. However, representative national estimates of iron deficiency (ID) are not available. OBJECTIVES: The objective of the present study was to evaluate ID prevalence among children and adolescents (1-19 y) using nationally representative data and to examine the sociodemographic patterning of ID. METHODS: Cross-sectional data from the Comprehensive National Nutrition Survey in children (1-4 y: n = 9635; 5-9 y: n = 11,938) and adolescents (10-19 y; n = 11,507) on serum ferritin (SF) and other biomarkers were analyzed to determine inflammation-adjusted ID prevalence [SF (µg/L): <12 in 1-4 y and <15 in 5-19 y] and its relation to sociodemographic indicators. Multiple-regression analyses were conducted to identify the exposure associations of iron status. In addition, the relation between SF and hemoglobin was assessed as an indicator of iron utilization in different wealth quintiles. RESULTS: ID prevalence was higher in 1- to 4-y-old children (31.9%; 95% CI: 31.0%, 32.8%) and adolescent girls (30.4%; 95% CI: 29.3%, 31.5%) but lower in adolescent boys and 5- to 9-y-old children (11%-15%). In all age groups, ID prevalence was higher in urban than in rural participants (1-4 y: 41% compared with 29%) and in those from richer quintiles (1-4 y: 44% in richest compared with 22% in poorest), despite adjustment for relevant confounders. SF significantly interacted with the wealth index, with declining trends in the strength of association between hemoglobin and SF from the richest to the poorest groups suggesting impaired iron utilization for hemoglobin synthesis in poorer wealth quintiles. CONCLUSIONS: ID prevalence was indicative of moderate (in preschool children and adolescent girls) or mild (in 5- to 9-y-old children and adolescent boys) public health problem with significant variation by state and age. Focusing on increasing iron intake alone, without addressing the multiple environmental constraints related to poverty, may not result in intended benefits.

BACKGROUND: It is thought that there is a high risk of zinc deficiency in India, but there are no representative national estimates. OBJECTIVES: We aimed to evaluate the national and state-level prevalence of low serum zinc concentrations (SZCs) in Indian children from the nationally representative Comprehensive National Nutrition Survey. METHODS: Prevalence of low SZC, adjusted for C-reactive protein, was estimated among preschool (1-4 y; n = 7874) and school-age children (5-9 y; n = 10,430) and adolescents (10-19 y; n = 10,140), using SZC cutoffs defined by the International Zinc Nutrition Consultative Group. RESULTS: Prevalence of low SZC was high among adolescents (31.1%; 95% CI: 29.8%, 32.4%), compared with school-age (15.8%; 95% CI: 15.3%, 16.3%) or preschool children (17.4%; 95% CI: 16.7%, 18.0%). However, stratification of prevalence by fasting status or using an alternative lower SZC cutoff independent of fasting status led to a reduction in prevalence by 3.7% or 7.8% in children <10 y, respectively. The prevalence of low SZC was higher among rural preschool children, those belonging to households with poor socioeconomic status, and those with severe stunting or underweight. Preschool children with diarrhea (22.6%; 95% CI: 20.8%, 24.4%), productive cough (22.7%; 95% CI: 18.5%, 27.5%), or malaria/dengue (38.5%; 95% CI: 29.4%, 48.2%) in the 2 wk preceding the survey had a higher prevalence of low SZC than those without morbidity (16.5%; 95% CI: 15.9%, 17.2%; 17.6%; 95% CI: 16.9%, 18.2%; and 17.5%; 95% CI: 16.8%, 18.1%, respectively). CONCLUSIONS: The national prevalence of low SZC among preschool (17%) or school-age children (16%) was <20%, which is considered the cutoff indicating a problem of public health significance; but there were variations by state and socioeconomic status. In adolescents, however, the prevalence of low SZC was 31%, which warrants further investigation. The association of low SZC with diarrhea in preschool children necessitates better coverage of Zn administration in the management of diarrhea.

BACKGROUND: The extended care model of the United Nations Children's Fund (UNICEF) identifies knowledge/beliefs, nutritional status, mental health, control of resources/autonomy, workload/time constraints and social support as important caregiver resources for childcare. The aim of this paper is to examine the role of mothers' caregiving resources in child-care practices in slums. METHODS: A cross-sectional study was conducted in 10 slums of Hyderabad, to appraise the caregiving practices and health status of children under 5 years. Data were collected from 506 households, selected through multistage stratified random sampling, and data relating to 451 children aged 6-59 months were analysed. Four caregiving practices were studied: psychosocial stimulation, as assessed by the Home Observation Measurement of the Environment inventory; hygienic care rated by spot-check observation; and meal frequency and dietary diversity based on maternal recall. The role of the mother's caregiving resources was examined using bivariate and multivariate logistic regression analyses. RESULTS: More than 50% of the children received good psychosocial stimulation and close to 60% had good hygienic care. About 75% of the children aged 6-23 months had the recommended minimum meal frequency and 13% had the recommended dietary diversity. Mother's media exposure (odds ratio [OR] 2.25, 95% confidence interval [CI] 1.35-3.77), participation in household budgeting (OR 2.19, CI 1.25-3.83) and husband's support (OR 2.04, CI 1.28-3.24) were predictors of psychosocial stimulation. Mother's younger age (OR 1.11, CI 1.04-1.18), poor media exposure (OR 1.95, CI 1.15-3.29), dissatisfaction with life (OR 1.84, CI 1.05-3.24), workload (OR 1.79, CI 1-3.18) and having no money for their own use (OR 1.52, CI 0.95-2.45) placed children at higher odds for receiving poor hygienic care. Leisure time (OR 2.75, CI 1.25-6.06) and participation in budgeting (OR 1.97, CI 1-3.86) were predictors of meal frequency. CONCLUSION: Mother's workload, poor media exposure, dissatisfaction with life, lack of husband's support and absence of economic autonomy are constraints to good child care in slums.
