Impact of zinc supplementation on mental and psychomotor scores of children aged 12 to 18 months: a randomized, double-blind trial

Objective: To evaluate the effect of zinc supplementation on mental and psychomotor scores in children aged 12 to 18 months. Study design: In this double-blind, randomized, placebo-controlled trial, children aged 6 to 30 months received daily elemental zinc (10 mg for infants and 20 mg for others) or placebo for 4 months. Bayley Scales of Infant Development II were used for development assessment in the 12- to 18-month subgroup at enrollment and the end of the study. Results: At the end of the study, the adjusted mean mental (P = 0.36) and psychomotor (P = 0.28) index scores were similar in the intervention and control groups. In a multivariate model, the baseline mental development index score was positively associated with the mother's schooling, the child's height for age, packed cell volumes, hospital birth, and attendance at a day care center, and was negatively associated with the child's age. Breastfeeding, the child's weight for height, and packed cell volumes were positively associated with the baseline psychomotor index score. Conclusion: Zinc supplementation did not affect the mental or psychomotor development index scores in a setting in which zinc deficiency is common

Breast-feeding status alters the effect of vitamin A treatment during acute diarrhea in children

Vitamin A administration in children reduces the incidence of severe diarrhea during the subsequent few months. We therefore examined the effect of treatment with vitamin A during acute diarrhea on the episode duration and severity. In a double-blind controlled field trial, 900 children 1 to 5 y of age with acute diarrhea of ≤ 7 d duration were randomly assigned to receive vitamin A (60 mg) or a placebo. Children were followed up at home every alternate day until they recovered from the diarrheal episode. In all study children, those treated with vitamin A had a significantly lower risk of persistent diarrhea [odds ratio (OR) 0.30, 95% confidence interval (CI) 0.07-0.97], but there was no effect on the mean diarrheal duration or the mean stool frequency. In the subgroup of children who were not breast-fed, the mean diarrheal duration [ratio of geometric means (GM) 0.84, 95% CI 0.72-0.97], mean number of stools passed after the intervention (ratio of GM 0.73, 95% CI 0.56-0.95), the proportion of episodes lasting ≥ 14 d (P = 0.002) and the percentage of children who passed watery stools on any study day (OR 0.40, 95% CI 0.21-0.77) were significantly lower in those treated with vitamin A. We conclude that administration of vitamin A during acute diarrhea may reduce the severity of the episode and the risk of persistent diarrhea in non-breast-fed children. Similar benefit was not seen in breast-fed children

Careseeking for illness in young infants in an urban slum in India

Illness in infants in the first two months of life can take a precipitous life-threatening course, and requires timely and appropriate medical assessment and management. We conducted a focused ethnographic study of illness in young infants and associated careseeking practices in an urban slum in New Delhi, India, in order to identify the constraints in securing effective care for severe illness in this age group. The findings suggest that maternal recognition of illness is not a limiting factor in the use of health care services for sick young infants in this setting. Mothers respond to a number of important signs of illness, including changes in the young infant's sleeping or feeding behavior, and they are usually prompt in seeking care outside the home. They are not able, however, to discriminate among the many sources of health care available in this setting, and give preference to local unqualified private practitioners. Most practitioners, including qualified medical practitioners, display critical failures in the assessment and management of sick young infants. The continuity and effectiveness of care is further compromised by the caretakers' expectations of rapid cure, which result in discontinued treatment courses and frequent changes in practitioners, and by their reluctance to seek hospital care. The implications of these findings for the design of programs to reduce young infant mortality are discussed. In particular, the feasibility and acceptability of hospital referrals according to current program guidelines are called into question

Vitamin B12 and/or folic acid supplementation on linear growth; A 6 years follow-up study of a randomised controlled trial in early childhood in North India

Folate and vitamin B12 are essential for growth. Our objective was to estimate their long-term effects on linear growth in North Indian children. This is a follow-up study of a factorial designed, double-blind, randomised, placebo-controlled trial in 1000 young children. Starting at 6–30 months of age, we gave folic acid (approximately 2 RDA), vitamin B12 (approximately 2 RDA), both vitamins or a placebo daily for 6 months. Six years after the end of supplementation, we measured height in 791 children. We used the plasma concentrations of cobalamin, folate and total homocysteine to estimate vitamin status. The effect of the interventions, the association between height-for-age z-scores (HAZ) and baseline vitamin status, and the interactions between supplementation and baseline status were estimated in multiple regression models. Mean (SD) age at follow-up was 7·4 (0·7) years (range 6 to 9 years). There was a small, non-significant effect of vitamin B12 on linear growth and no effect of folic acid. We observed a subgroup effect of vitamin B12 supplementation in those with plasma cobalamin concentration < 200 pmol/l (Pfor interaction = 0·01). The effect of vitamin B12 supplementation in this group was 0·34 HAZ (95 % CI 0·11, 0·58). We found an association between cobalamin status and HAZ in children not given vitamin B12 (Pfor interaction = 0·001). In this group, each doubling of the cobalamin concentration was associated with 0·26 (95 % CI 0·15, 0·38) higher HAZ. Suboptimal vitamin B12 status in early childhood seemingly limits linear growth in North Indian children. © The Author(s), 2022.

Study of Phytochemical, Antioxidant and Antimicrobial Activity of Artocarpus heterophyllus

In today’s world, search for natural medicines is increasing as a result of drug resistance of pathogens and also due to negative consequences of antibiotic. Presence of phytochemicals, antioxidant potential and antimicrobial activity of Artocarpus heterophyllus was carried out in this study. Leaf of this plant was subjected to warm extraction with three different solvents namely methanol, aqueous methanol and ethyl acetate. Leaf extract showed the presence of coumarin, alkaloid, terpenoid in methanol solvent; tannin, coumarin, saponin in aqueous methanol extract and coumarin, terpenoids in ethyl acetate solvent. Further, antimicrobial activity was assessed through disc diffusion method with six pathological bacteria and two fungi strains in four different concentrations of plant extract. Largest ZOI of 16mm was obtained against B. subtilis in 200mg/ml concentration for ethyl acetate extract. Antioxidant potential was measured by DPPH (Diphenyl-2-picrylhydrazyl) assay. DPPH free radical Scavenging Activity was expressed in % inhibition with L Ascorbic acid as standard and leaf extract in methanol showed the best activity

Vitamin A Administered with measles vaccine to nine-month-old infants does not reduce vaccine immunogenicity

After a report of reduced seroconversion to measles in infants, aged 6 mo, given vitamin A with their measles vaccination, serious concerns were raised regarding the safety of the WHO's recommendation that infants be supplemented with vitamin A at the time of measles immunization. To determine the impact of coadministered vitamin A on the antibody response to measles vaccine given to infants aged 9 mo, the more common age for immunization in developing countries, we conducted a randomized, double-blind, placebo-controlled trial in an urban slum community in Delhi. Infants (618) were randomly allocated to receive 30 mg vitamin A or a placebo with the measles immunization. Antibodies to measles were measured by ELISA in serum samples obtained at before (baseline) and 12 wk after immunization. Overall, the seroconversion rates did not differ between vitamin A (89.5%) and placebo (87.6%) groups. There were no significant differences in the geometric mean titers in the two groups (ratio of geometric means, 1.19; 95% confidence interval, 0.97-1.46). Among malnourished infants, the geometric mean titer was significantly greater in the vitamin A group compared to the placebo group (ratio of geometric means, 1.57; 95% confidence interval, 1.18-2.0), but seroconversion rates did not differ. There were no differences in seroconversion rates and geometric mean titers in the two study groups among the well-nourished children. These results indicate that 30 mg vitamin A does not reduce the immune response to the coadministered vaccine and, therefore, can be continued to be given safely in public health programs

Impact on inequities in health indicators: effect of implementing the integrated management of neonatal and childhood illness programme in Haryana, India

Background: A trial to evaluate the Integrated Management of Neonatal and Childhood Illness (IMNCI) strategy showed that the intervention resulted in lower infant mortality and improved infant care practices. In this paper, we present the results of a secondary analysis to examine the effect of the IMNCI strategy on inequities in health indicators. Methods: The trial was a cluster-randomized controlled trial in 18 primary health centre areas. For this analysis, the population was divided into subgroups by wealth status (using Principal Component Analysis), religion and caste, education of mother and sex of the infant. Multiple linear regression analysis was used to examine inequity gradients in neonatal and post-neonatal mortality, care practices and care seeking, and the differences in these gradients between intervention and control clusters. Findings: Inequity in post-neonatal infant mortality by wealth status was lower in the intervention as compared to control clusters (adjusted difference in gradients 2.2 per 1000, 95% confidence interval (CI) 0 to 4.4 per 1000, P = 0.053). The intervention had no effect on inequities in neonatal mortality. The intervention resulted in a larger effect on breastfeeding within one hour of birth in poorer families (difference in inequity gradients 3.0%, CI 1.5 to 4.5, P &#60; 0.001), in lower caste and minorities families, and in infants of mothers with fewer years of schooling. The intervention also reduced gender inequity in care seeking for severe neonatal illness from an appropriate provider (difference in inequity gradients 9.3%, CI 0.4 to 18.2, P = 0.042). Conclusions: Implementation of IMNCI reduced inequities in post-neonatal mortality, and newborn care practices (particularly starting breastfeeding within an hour of birth) and health care-seeking for severe illness. In spite of the intervention substantial inequities remained in the intervention group and therefore further efforts to ensure that health programs reach the vulnerable population subgroups are required

Vitamin B12, folate, and cognition in 6-to 9-year-olds: a randomized controlled trial

BACKGROUND AND OBJECTIVES: Vitamin B12 and folate are important for normal brain development. Our objective for this study was to measure the effects of 6-month supplementation of vitamin B12 and/or folic acid in early childhood on cognition when the children were 6 to 9 years old. METHODS: The study is a follow-up of a factorial randomized, double-blind, placebo-controlled trial in 1000 North Indian children. Children 6 to 30 months of age were randomly assigned to receive a placebo or 1.8 µg of vitamin B12, 150 mg of folic acid, or both daily for 6 months. After 6 years, we re-enrolled 791 of these children for cognitive assessments. We compared the scores of the main outcomes (the Wechsler Intelligence Scale for Children, Fourth Edition [India], the Crichton Verbal Scale, and subtests of the NEPSY-II) between the study groups. We also measured the associations between markers of the B vitamins (plasma cobalamin, folate, and total homocysteine concentrations) in early childhood and the cognitive outcomes. RESULTS: There were no differences between the intervention groups and the placebo group on the cognitive outcomes. Plasma cobalamin, folate, and total homocysteine concentrations in early childhood were associated with the cognitive outcomes at follow-up in the unadjusted models. These associations disappeared in models adjusted for relevant confounders. CONCLUSIONS: Our findings, from both an observational and a randomized design suggest that vitamin B12 and folate in children 6 to 36 months have limited public health relevance for long-term cognition.Thrasher Research Fund (grant 02827) and the Research Council of Norway (grants 172226 and 234495) provided financial support for the original and the follow-up study.AcceptedVersio

Use of multiple opportunities for improving feeding practices in under-twos within child health programmes

Objectives: In a community randomized trial, we aimed to promote exclusive breastfeeding and appropriate complementary feeding practices in under-twos to ascertain the feasibility of using available channels for nutrition counselling, their relative performance and the relationship between intensity of counselling and behaviour change. We also assessed whether using multiple opportunities to impart nutrition education adversely affected routine activities. Methods: We conducted a community randomized, controlled effectiveness trial in rural Haryana, India, with four intervention and four control communities. We trained health and nutrition workers in the intervention communities to counsel mothers at multiple contacts on breastfeeding exclusively for 6 months and on appropriate complementary feeding practices thereafter. The intervention was not just training health and nutrition workers in counselling but included community and health worker mobilization. Findings: In the intervention group, about 32% of caregivers were counselled by traditional birth attendants at birth. The most frequent sources of counselling from birth to 3 months were immunization sessions (45.1%) and home visits (32.1%), followed closely by weighing sessions (25.5%); from 7 to 12 months, home visits (42.6%) became more important than the other two. An increase in the number of channels through which caregivers were counselled was positively associated with exclusive breastfeeding prevalence at 3 months (p = 0.002), consumption of milk/cereal gruel or mix use at 9 months (p = 0.004) and 18 months (p = 0.003), undiluted milk at 9 months (p &lt; 0.0001) and 24 hour non-breast-milk energy intakes at 18 months (p = 0.023), after controlling for potential confounding factors. Intervention areas, compared with the control, had higher coverage for vitamin A (45% vs. 11.5%) and iron folic acid (45% vs. 0.4%) supplementation. Conclusions: Using multiple available opportunities and workers for counselling caregivers was feasible, resulted in high coverage and impact, and instead of disrupting ongoing services, resulted in their improvement
