Abstract
In the third week of September 2022, an outbreak of measles was reported from a slum in Eastern Mumbai, India. We sought to investigate whether failure to vaccinate or vaccine failure was the cause. We constructed an epidemic curve, drew a spot map, and calculated the attack rate and case-fatality ratio. We calculated vaccine effectiveness (VE) for one and two doses of measles vaccine in an unmatched case-control study and did stratified analysis by sex, availability of vaccination card, and migrant status. We identified 358 cases and four deaths with a 11.3% attack rate and 1.1% case fatality, both being highest among 0-24-month-old boys. The epidemic curve suggested a propagated mode of spread. The VE for two doses was 64% (95% confidence interval (CI): 23-73%) among under-5-year-old children and 70% (95% CI: 28-88%) among 5-15-year-old children. Failure to vaccinate, consequent to the COVID-19 pandemic, and vaccine hesitancy might have led to the accumulation of susceptible children in the community. Additionally, the occurrence of case-patients among vaccinated suggests reduced VE, which needs further investigation into humoral and cell-mediated immunity as well as contributory factors including nutritional status. Outbreak response immunization to complete immunization of missed and dropout children was carried out to control the outbreak.

Abstract
BACKGROUND Infants born with low birth weight (LBW), i.e. less than 2500g, is considered an important factor of malnutrition in Asia. In India, research related to this issue is still neglected and limited. Evidence exists that a large number of child deaths occur in India due to maternal and child malnutrition-related complications. Moreover, it has been found that the cost of malnutrition in India results in a significant reduction of the country's Gross Domestic Product (GDP). Thus, in this current context, this study aims to explore the contribution of low birth weight to childhood undernutrition in India. METHODS The study used data from the 5th round of the National Family Health Survey (NFHS-5), a large-scale survey conducted in India. The survey collected information from 176,843 mothers and 232,920 children. The study used the last birth information (last children born 5 years preceding the survey) due to the detailed availability of maternal care information. Univariate and bivariate analyses were conducted to determine the percentage distribution of outcome variables. Multivariate logistic regression was employed to examine the association between LBW and undernutrition (stunting, wasting, and underweight). The study also used the Fairlie decomposition analysis to estimate the contribution of LBW to undernutrition among Indian children. RESULTS The results show that childhood undernutrition was higher in states like Uttar Pradesh, Bihar, Jharkhand, Gujarat, and Maharashtra. The results of the logistic regression analysis show that infants born with low birth weight were more likely to be stunted (OR = 1.46; 95% CI: 1.41-1.50), wasted (OR = 1.33; 95% CI: 1.27-1.37), and underweight (OR = 1.76; 95% CI: 1.70-1.82) in their childhood compared to infants born without low birth weight. The findings from the decomposition analysis explained that approximately 14.8% of the difference in stunting, 10.4% in wasting, and 9.6% in underweight among children born with low birth weight after controlling for the individuals' selected characteristics. CONCLUSION The findings suggest that LBW has a significant contribution to malnutrition. The study suggests that policymakers should prioritize strengthening maternal and child healthcare schemes, particularly focusing on antenatal and postnatal care, as well as kangaroo mother care at the grassroots level to reduce the burden of LBW and undernourished children.

Abstract
Under-five mortality rate (U5MR) differs by rural-urban place of residence and mother's education; however, the rural-urban gap in U5MR by mother's educational attainment is unclear in the existing literature. Using five rounds of the national family health surveys (NFHS I-V) conducted between 1992-93 and 2019-21 in India, this study estimated the main and interaction effects of rural-urban and maternal education on U5MR. The mixed effect Cox proportional hazard (MECPH) model was used to predict the risk of under-five mortality (U5M). The finding shows that unadjusted U5MR remained 50 per cent higher in rural areas than in urban areas across the surveys. Whereas, after controlling for demographic, socioeconomic, and maternal health care predictors of U5M, the MECPH regression results indicated that urban children had a higher risk of death than their rural counterparts in NFHS I-III. However, there are no significant rural-urban differences in the last two surveys (NFHS IV -V). In addition, increasing maternal education levels were associated with lower U5M in all surveys. Though, in recent years, primary education has had no significant effect. The U5M risk was additionally lower for urban children than rural children whose mothers had secondary and higher education by NFHS-III; however, this additional urban advantage was no longer significant in recent surveys. The higher impact of secondary education on U5MR in urban areas in the past may be attributed to poor socio-economic, healthcare conditions in rural areas. Overall, maternal education, particularly secondary education, remained a protective factor for U5M in both rural and urban areas, even after controlling for predictors. Therefore, there is a need to increase the focus on secondary education for girls for a further decline in U5M.

Abstract
BACKGROUND This study characterized undernutrition among children (0-24 months) by age groups specified for Infant and Young Child-feeding (IYCF) and determined the association between child malnutrition and IYCF. METHODS This cross-sectional survey recruited mother-children dyads (N = 1443). WHO standards were used to assess nutritional status and IYCF indicators. Multivariate analyses were performed to assess the association between IYCF and nutritional indicators. RESULTS Stunting, underweight, wasting, overweight, and obesity were prevalent in 33.1%, 26%, 20.2%, 4.6%, and 2.9% of the children, respectively. Age-wise distribution of undernutrition identified severity of stunting and underweight at 10-24 months (median < -1.6 SD; < -1.2 SD; 25th percentile at -2.6 & -2.2 SD respectively) and wasting highest at 0-6 months (25th percentile close to -2SD). Boys manifested higher stunting (lower value -5.2 SD) and were more wasted (lower value -4.7 SD). IYCF prevalence recorded early initiation at 45.2%, exclusive breastfeeding at 23.1%, and prelacteal and bottle-feeding at 37.5 and 22.5% respectively. Child minimum diet diversity (MDD) ≥4 was not achieved by 84%. Minimum meal frequency and minimum acceptable diet were achieved by 75% and 14% respectively. Bottle-feeding increased the odds of wasting [AOR: 1.501 (95% CI: 1.062-2.121)], severe stunting [AOR: 1.595 (95% CI: 1.079-2.358)] and underweight [AOR: 1.519 (95% CI 1.102-2.094)]. Wasting according to BAZ scores was associated with delayed initiation of breastfeeding [AOR: 1.387 (95% CI: 1.018-1.889)] and bottle feeding [AOR: 1.538 (95% CI: 1.087-2.175)]. Delayed introduction of complementary feeding increased the odds of severe stunting [AOR: 2.189 (95% CI: 1.090-4.399)]. Formula feeding increased the odds of underweight [AOR: 1.738 (95% CI: 1.046-2.888)] and obesity [AOR: 4.664 (95% CI: 1.351-16.10)]. Prelacteal feeding increased the odds of severe forms of stunting and underweight by 56% and 79% respectively, and overweight by 96%. CONCLUSION Setting and age-specific interventions to improve age-appropriate child-feeding practices are vital to address the double burden of malnutrition in the critical age group.

Abstract
The 2015/2016 National Family Health Survey (NFHS-4) revealed that the prevalence of anemia among children under 5 years is 58% in India. Lack of nutritional supplementation and lack of health care facilities are found to be important influential factors of anemia among children. We aimed to examine district-level spatial heterogeneity and clustering of associated factors with childhood anemia in India. Geographically weighted regression was applied on the NFHS-5 data for 335 districts. Factors such as prevalence of nutritional supplementation in children and mothers, birth order, antenatal care, diarrhea in children, and stunting were found to be significantly associated. Spatial scan statistics technique identified 3 significant local spatial clusters of anemia. This study provides findings based on the latest available data which can further assist in the design and execution of tailor-made policies.

Abstract
Background Even with optimum breastfeeding, children are at risk of being stunted if they do not receive timely adequate and appropriate complementary feeding. Objectives The objective is to determine the prevailing complementary feeding practices, and nutritional status of children aged 6-23 months. Materials and Methods Mothers of 350 children of age 6--23 months of an urban resettlement colony of East Delhi were interviewed using a pre-tested questionnaire based on the WHO indicators to record their complementary feeding practices. Weight and height was taken to assess the nutritional status. Results The minimum meal frequency was adequate in 60.6%, minimum dietary diversity in 15.1%, and minimum acceptable diet in 9% children. The prevalence of wasting was 43.7%, underweight 43.4%, and stunting 29.1%, as per Z-score. Statistically significant association of wasting with low birth weight, bottle feeding, and consumption of market food was observed (P < 0.05). Conclusions Complementary feeding indicators were unsatisfactory in most children. A high prevalence of wasting and under-nutrition was observed.

Abstract
BACKGROUND AND AIMS To compute reliable estimates of stunting, wasting and underweight along with their determinants in under 5 children from Developing Countries. METHODS Out of 190 studies on under-nutrition, accessed from PubMed and Google database, 24 studies meeting the selection criteria were considered for meta-analysis. RESULTS Overall estimate of prevalence of stunting, wasting and underweight were 43.4%, 17.8% and 35.5% respectively. Mother's education, BMI, height, wealth index, child birth-weight and sex were factors significantly associated with stunting, wasting and underweight. CONCLUSIONS Prevalence of stunting, wasting and underweight in Developing Countries were quite high. To carry-out differentials of under-nutrition between countries and ways of its reduction, more such studies are required.

Abstract
Pediatric acute gastroenteritis (PAGE) is a significant cause of morbidity, mortality and healthcare costs in many countries, but differences in PAGE vary from country-to-country; thus, we limited our analysis to 1 country. Probiotics have been recommended as an adjunct to standard treatment, but the choice of probiotic is unclear. PubMed, Google Scholar, and reviews were searched from inception to May 2020 for randomized controlled trials (RCTs) in India using probiotics for a treatment for PAGE. Meta-analyses using subgroups of identical probiotic types (≥2 RCT/type) were conducted for primary outcomes (duration of diarrhea, cured by day 3, rapidity of response, and length of hospital stay). Twenty-two RCTs were included in the systematic review (N = 4059 participants) including 5 single-strained probiotics and 3 multi-strained mixtures. For the meta-analyses, 17 RCT (20 treatment arms) were included. Saccharomyces boulardii CNCM I-745 had the strongest effect on shortening the duration of diarrhea (standardized mean difference, -1.86 d; 95% confidence interval, -2.8 to -0.9), while both Lactobacillus rhamnosus GG and a mixture of 4 Bacillus clausii strains (O/C, SIN, N/R, T) significantly reduced the duration of diarrhea (-1.7 and -1.4 d, respectively). S. boulardii and L. rhamnosus GG significantly reduced hospital stays (-1.8 and -1.1 d, respectively), while B. clausii had no effect. The frequency of stools/day was significantly reduced by day 4 for S. boulardii and by day 5 for L. rhamnosus GG. In India, 2 types of probiotics (S. boulardii CNCM I-745 and L. rhamnosus GG) significantly shortened both the duration of diarrhea and hospitalization stays in pediatric patients with PAGE. While these 2 probiotic strains were safe and effective for children in India, further research is needed to confirm if other probiotic strains or mixtures may be effective.

Abstract
Background: The nutritional status of children is influenced by feeding practices. Infant and Child Feeding Index (ICFI) is an age-specific composite index to assess the feeding practices of children. Objectives: To determine the association between ICFI and the nutritional status of children aged 6 to 24 months. To find whether ICFI has value as a tool for detecting poor nutritional status. To determine the association of ICFI and nutritional status with sociodemographic and other factors. Methods: A cross-sectional study was conducted in the urban field practice area of a tertiary care institute among 149 children aged 6 to 24 months and their mothers. Data on feeding practices were obtained and ICFI scores were calculated. The weight and length of the children were measured and Z scores (WAZ, LAZ, and WLZ) were calculated. A Chi-square test was used to find the association between the categorical variables. Results: We found no association between ICFI and any of the three nutritional indicators such as WAZ, LAZ, and WLZ. The sensitivity of the ICFI was low for detecting underweight (10.0%), stunting (29.4%), and wasting (11.1%). ICFI was significantly associated with the growth monitoring of children and mothers' education. WAZ was significantly associated with mother's education and socioeconomic class. Conclusions: There is no association between ICFI and the nutritional status of children. ICFI has limited value in detecting the poor nutritional status of children in this urban setting. Maternal education and growth monitoring of children play an important role in infant and child feeding practices.

Abstract
In this cross-sectional study, we describe the composition and diversity of the gut microbiota among undernourished children living in urban slums of Mumbai, India, and determine how nutritional status, including anthropometric measurements, dietary intakes from complementary foods, feeding practices, and micronutrient concentrations, is associated with their gut microbiota. We collected rectal swabs from children aged 10 to 18 months living in urban slums of Mumbai participating in a randomized controlled feeding trial and conducted 16S rRNA sequencing to determine the composition of the gut microbiota. Across the study cohort, Proteobacteria dominated the gut microbiota at over 80% relative abundance, with Actinobacteria representation at <4%, suggesting immaturity of the gut. Increased microbial α-diversity was associated with current breastfeeding, greater head circumference, higher fat intake, and lower hemoglobin concentration and weight-for-length Z-score. In redundancy analyses, 47% of the variation in Faith's phylogenetic diversity (Faith's PD) could be accounted for by age and by iron and polyunsaturated fatty acid intakes. Differences in community structure (β-diversity) of the microbiota were observed among those consuming fats and oils the previous day compared to those not consuming fats and oils the previous day. Our findings suggest that growth, diet, and feeding practices are associated with gut microbiota metrics in undernourished children, whose gut microbiota were comprised mainly of Proteobacteria, a phylum containing many potentially pathogenic taxa.IMPORTANCE The impact of comprehensive nutritional status, defined as growth, nutritional blood biomarkers, dietary intakes, and feeding practices, on the gut microbiome in children living in low-resource settings has remained underreported in microbiome research. Among undernourished children living in urban slums of Mumbai, India, we observed a high relative abundance of Proteobacteria, a phylum including many potentially pathogenic species similar to the composition in preterm infants, suggesting immaturity of the gut, or potentially a high inflammatory burden. We found head circumference, fat and iron intake, and current breastfeeding were positively associated with microbial diversity, while hemoglobin and weight for length were associated with lower diversity. Findings suggest that examining comprehensive nutrition is critical to gain more understanding of how nutrition and the gut microbiota are linked, particularly in vulnerable populations such as children in urban slum settings.

Abstract
Half the children under the age of 5 years in Papua New Guinea (PNG) are undernourished, more than double the global average with rural areas disproportionately affected. This study examines factors associated with stunting, wasting and underweight in cocoa growers' children (<5 years) in the Autonomous Region of Bougainville (ARoB), using data from a comprehensive 2017 cross-sectional livelihoods survey. Sixteen independent predictors for stunting, wasting and underweight were selected based on the UNICEF Conceptual Framework of Determinants of Undernutrition. We used multilevel logistic mixed regression models to measure the association of the explanatory variables with stunting, wasting and underweight. At the household level, the adjusted OR (aOR) of stunting (aOR=1.71,95% CI 1.14 to 2.55) and underweight (aOR=2.11, 95% CI 1.16 to 3.82) increased significantly among children from households with unimproved toilet facilities. The aOR for underweight also increased among children from households without access to clean drinking water (aOR=1.97, 95% CI 1.19 to 3.29). Short maternal stature was significantly associated with child stunting, the odds increased as maternal height decreased (from 150 to <155 cm, aOR=1.52, 95% CI 1.02 to 2.26) (<150 cm, aOR=2.37, 95% CI 1.29 to 4.35). At the individual level, the odds of a child being underweight increased with birth order (second born, aOR=1.92, 95% CI 1.09 to 3.36; third born, aOR=6.77, 95% CI 2.00 to 22.82). Compared with children less than 6 months, children aged 6-23 months and 24-59 months had a higher odds of being stunted (aOR=3.27, 95% CI 1.57 to 6.78 and aOR=2.82, 95% CI 1.40 to 5.67) and underweight (aOR=4.83, 95% CI 1.36 to 17.24 and aOR=4.59, 95% CI 1.29 to 16.26). No variables were found to be significant for wasting. Interventions that simultaneously target key life stages for women and children and the underlying social and environmental determinants are required for sustained improvements to undernutrition.

Abstract
INTRODUCTION Undernutrition is continuing to be a major public health problem in India. Moreover, India houses more than 30% of the world's stunted children aged under 5 years. There was a paucity of a community-based cross-sectional study on the nutrition of children aged under 5 years in urban Delhi. Therefore, we conducted this study to assess the prevalence of undernutrition and their associated factors in children aged under 5 years in urban South Delhi. MATERIALS AND METHODS A cross-sectional community-based study was conducted in the Mehrauli area of South Delhi with a semi-structured questionnaire. Systematic random sampling without replacement was implemented. Informed written consent was sought from the parents of participants. Questions were asked regarding demography and sociocultural factors of the participants. Anthropometry measurements were obtained. Underweight and stunting were defined using WHO child growth standards 2006. RESULTS A total of 520 participants in 695 houses were contacted and interviewed. Prevalence of underweight and stunting were 34.0% and 42.6%, respectively. Sociocultural factors, associated with underweight and stunting, found in current study were fathers' education (with both, P value < 0.05), mothers' education (with both, P value < 0.05), poverty status (with both, P value <0.05), overcrowding (stunting only, P value <0.05), fathers' alcohol abuse (with both, P value < 0.05) and exclusive breastfeeding for 6 months (stunting only, P value <0.05). RESULTS A total of 520 participants in 695 houses were contacted and interviewed. Prevalence of underweight and stunting were 34.0% and 42.6%, respectively. Sociocultural factors, associated with underweight and stunting, found in current study were fathers' education (with both, P value < 0.05), mothers' education (with both, P value < 0.05), poverty status (with both, P value <0.05), overcrowding (stunting only, P value <0.05), fathers' alcohol abuse (with both, P value < 0.05) and exclusive breastfeeding for 6 months (stunting only, P value <0.05). CONCLUSIONS There was a very high prevalence of underweight (34.0%) and stunting (42.6%) in children under 5 years age in Mehrauli.
