Wasting and its associated factors among under-two years children in Ethiopia: a systematic review and meta-analysis.

INTRODUCTION: Globally, about 45 million under-five children have suffered from wasting where Asian and African countries have the major share of these wasted children. Despite wasting is affected all types of populations, the long and short term effect is more severe and sensitive in under-two aged children. Hence, this review was intended to assess pooled prevalence and associated factors of wasting among under-two children in Ethiopia. METHODS: The search was done using electronic data bases (Hinari, PubMed, Google scholar, Scopus) and research repositories from June 19-22/2023. The review included articles published between January 2013 and December 2023.The study included Cross-sectional/case control studies which report the prevalence and associated factors of wasting in under-two aged children. The quality of included studies was assessed using the Joanna Briggs Institute (JBI) quality assessment checklists for observational studies. The presence of heterogeneity between included studies was evaluated using Cochrane Q-test and the I2 statistics. Publication bias was checked through graphical and statistical test. Associated factors were estimated by random effect model using DerSimonian-Laird model weight. RESULTS: The pooled prevalence of wasting among under-two children was 10.91% (95% CI: 8.97-12.85; I2 = 86.36%). Absence of maternal antenatal follow up (OR; 3.23: 95%CI: 1.20-5.26), no exclusive breast feeding until six months (OR; 5.30; 95%CI: 1.17-9.43), current illness of the child (OR; 2.58: 95%CI: 1.78-3.37), large family size (OR; 12.38; 95%CI: 1.37-26.13) and low wealth status of the households (OR; 3.91; 95%CI: 1. 54-8.36) were significant factors of wasting among under-two children. CONCLUSIONS: This study disclosed that the pooled prevalence of wasting among under- two children were high in Ethiopia. Absence of maternal antenatal follow up, no exclusive breast feeding, low wealth status of the households, large family size and current illness of the child were significant factors of wasting. Strictly adherence of maternal antenatal follow up, counsel the parents to feed only breast milk until six months, limit the number of family size to the level of the household income and early treatment of the sick child were recommended. Furthermore, scale up the wealth status and living standard of the family can address the agenda of reducing and eradicating all forms of malnutrition.

Undernutrition and its determinants among children aged 6-59 months in Southern Ethiopia.

Malnutrition is responsible for over one-third of deaths among children under the age of five in low-and middle-income countries, including Ethiopia, and is largely preventable. The objective of this study was to determine the prevalence of undernutrition and its contributing factors among children aged 6-59 months in the Gedio zone of Southern Ethiopia. A community-based cross-sectional study design was used, and data were collected from 403 children and their mothers selected through random sampling technique. Anthropometric measures were converted to Z-scores using WHO-Anthro version 3.2.2 software. The prevalence of underweight, wasting, and stunting were 19.7% (95% CI 16-24%), 10% (95% CI 7-13%), and 49% (95% CI 44-54%) respectively. Low birth weight (AOR = 2.8, 95% CI (1.585-4.895), feeding non-diversified diet (AOR = 1.9, 95% CI (1.036-3.497), and being unvaccinated (AOR: 2.0; 95%CI (1.013-4.197) were significantly associated with being underweight. Family size of ≥ 5 (AOR = 4.4, CI (1.274-5.059), meal frequency of < 3 times per a day (AOR = 2.3, CI (1.037-5.024), and index birth interval of < 24 months (AOR = 2.2, CI (1.015-4.843) were significantly associated with wasting. Similarly, children aged ≥ 24 months (AOR = 2.8, CI (1.769-4.474), feeding non-diversified diet (AOR = 1.8, CI (1.153-2.894), total duration of breast-feeding < 12 months (AOR = 4.0, CI (2.547-6.429), and mothers BMI below 18.5 (AOR = 2.2, CI (1.328-3.718) were identified as a predictors of stunting. The study revealed significant levels of undernutrition, including underweight, wasting, and stunting, among children in the study area. Factors such as birth weight, dietary diversity score, and vaccine status were found to be strongly linked to underweight. Additionally, living in a large family, meal frequency, and birth interval were significantly associated with wasting. The age of the child, duration of breastfeeding, dietary diversity score, and maternal BMI status were also significantly linked to stunting. To address this issue, the study recommends promoting healthier feeding practices, dietary diversification, optimal breastfeeding, complete vaccination, wider birth intervals, and improving maternal nutrition to reduce undernutrition among children aged 6-59 months in the area. Implementing these measures could significantly improve the health of children in the study area.

Risk or associated factors of wasting among under-five children in Bangladesh: A systematic review.

BACKGROUND AND OBJECTIVES: Wasting among under-five years old (U-5) children is a significant global public-health-nutrition burden. To effectively address this problem in Bangladesh, knowing its prevalence, caus-es and associated-factors are essential. This review aimed to identify evidences available in the existing-accessible literature/documents that describe the individual, socioeconomic, demographic, and contextual risk-factors associated with wasting among U-5 children in Bangladesh. METHODS AND STUDY DESIGN: Electronic-databases included were MEDLINE, EMBASE, CINAHL, WoS, and Cochrane-Library written in English and published until 29 February 2024. RESULTS: The search from the five databases yielded 167 publications. Of these, 50 papers/articles were duplicates and 108 were irrelevant, and nine have met the inclusion criteria. Additionally, 22 articles/documents were identified from other sources. Finally, a total of 31 articles/documents have been included in this review. The odds of childhood wasting observed were high for smaller birth-size, higher birth-order, male child, 12-24 months age-group, improper breastfeeding- and complementary-feeding practices, not-receiving DPT1 and/or measles vaccine, ≥1 sibling(s), maternal-undernutrition, less food-consumption during pregnancy, lack of maternal-education, lack of hand-washing practices by the mother/caregiver, paternal tobacco use, lower socioeconomic-status, food-insecurity, lack of access to hygienic-latrine and/or improved-water, Monsoon season (May-August), flood exposure, living es-pecially in Barishal, Rajshahi Chittagong and Rangpur-division and/or Eastern part of Bangladesh, and urban-slum. CONCLUSIONS: The risk/associated factors of wasting among U-5 children in Bangladesh were found at various multilevel. Rarely caused by any one factor alone, wasting in U-5 children results from an interplay between pregnant-mother's health and nutrition, child-caring practices, diets, poverty, and disease, which vary by context.

Prevalence and associated risk factors of stunting, wasting/thinness, and underweight among primary school children in Kandahar City, Afghanistan: a cross-sectional analytical study.

BACKGROUND: Undernutrition, which includes stunting, wasting, and underweight, is a global problem, especially among children of low- and middle-income countries. To our knowledge, this study is first of its type from Afghanistan. Its main objectives were to estimate the prevalence and associated risk factors of stunting, wasting/thinness, and underweight among urban primary school children in Kandahar city of Afghanistan. METHODS: This school-based cross-sectional study was conducted among 1205 primary school children aged 6-12 years during a period of six months (October 2022-March 2023). Anthropometric measurements and other data were collected from all the participants. Data were analyzed by using descriptive statistics, Chi square test (using crude odds ratio or COR), and multivariate logistic regression (using adjusted odds ratio or AOR). RESULTS: Among the 1205 enrolled government school students, 47.4%, 19.5%, and 25.6% had stunting, wasting/thinness, and underweight, respectively. Statistically significant factors associated with stunting were age group 6-9 years (AOR 1.3, 95% CI 1.1-1.7), being girl (AOR 2.3, 95% CI 1.8-3.0), poverty (AOR 2.2, 95% CI 1.5-3.2), large family (AOR 3.0, 95% CI 2.4-3.9), illiterate mother (AOR 1.6, 95% CI 1.0-2.6), jobless head of the family (AOR 3.3, 95% CI 2.3-4.8), and skipping breakfasts (AOR 1.7, 95% CI 1.2-2.3). Main factor associated with wasting/thinness were age group 6-9 years (AOR 30.5, 95% CI 11.8-78.7), skipping breakfasts (AOR 22.9, 95% CI 13.9-37.8), and history of sickness during the past two weeks (AOR 17.0, 95% CI 6.6-43.8). Also, main factors associated with underweight were age group 6-9 years (AOR 2.6, 95% CI 1.6-4.1), skipping breakfasts (AOR 2.6, 95% CI 1.8-3.6), and poor sanitation (AOR 1.9, 95% CI 1.1-3.2). CONCLUSIONS: Stunting, wasting/thinness, and underweight are highly prevalent among primary school children (both girls and boys) in Kandahar city. It is recommended that local government (Afghanistan Ministry of Education and Ministry of Public Health) with the help of international organizations and donor agencies should implement comprehensive school-based feeding programs especially for girls. Health and nutrition education programs should be conducted with emphasis on nutrition of children aged 6-9 years as well as importance of healthy breakfast and good sanitation.

Malnutrition among Children under Age Five in Panama: Results of the ENSPA 2019.

Background: Malnutrition has important short- and long-term consequences in children under age five. Malnutrition encompasses undernutrition, overnutrition, and the coexistence of both of them, known as the double burden of malnutrition (DBM). Objective: The aim of this study was to estimate the prevalence of undernutrition, overnutrition, and the DBM among these children at the national level and by living area in Panama. Methods: Data from the National Health Survey of Panama (ENSPA, Spanish acronym), a population-based, cross-sectional study carried out in 2019 were used. Stunting, wasting, overweight, and obesity were defined according to the cut-off points of the World Health Organization Growth Standards. Undernutrition was defined as being stunted only, wasted only or both; overnutrition was defined as being overweight only or obese only; and the DBM was defined as the co-occurence of stunting and overweight/obesity in the same child. Prevalence and general characteristics at the national level and by living area were weighted. Findings: The prevalence of undernutrition was 15.3% (95% confidence interval (CI) 13.4-17.3) at the national level and 36.6% (CI: 30.1-43.5) in indigenous areas. The prevalence of overnutrition was 10.2% (8.2-12.6) at the national level and 11.9% (CI: 8.5-16.3), 8.4% (CI: 6.5-10.7) and 8.7% (CI: 5.2-14.3) in urban, rural and indigenous areas, respectively. The DBM prevalence was 1.4% (CI: 1.0-2.1) at the national level and 2.7% (CI: 1.4-5.1) in indigenous areas. Conclusions: Undernutrition is still the most prevalent malnutrition condition in our country. Panama has the highest prevalence of overnutrition in Central America. The highest prevalence of undernutrition and DBM was found among children living in indigenous areas.

Cross-sectional study of determinants of undernutrition among children aged 6-36 months in Kabul, Afghanistan.

OBJECTIVES: The current study aimed to find the distribution and factors associated with undernutrition among children aged 6-36 months in Kabul. DESIGN: Cross-sectional study. SETTING: Public Ataturk Children's Hospital, Kabul. PARTICIPANTS: 385. METHODS: A structured questionnaire was used to collect data on sociodemographic conditions and anthropometry of children. Logistic regression was used to find determinants of undernutrition. RESULTS: The distribution of stunting, wasting and underweight was 38.7%, 11.9% and 30.6%, respectively. Among the children studied, 54% did not receive breast milk within the first hour of birth, 53.2% were not exclusively breastfed, 21% received complementary feeding before the age of 6 months, 22.1% lacked access to safe water and 44.7% did not practise hand washing with soap. The odds of stunting were lower (p<0.05) in girls (AOR 5.511, 95% CI 3.028 to 10.030), children of educated fathers (OR 0.288, 95% CI 0.106 to 0.782), those from nuclear families (OR 0.280, 95% CI 0.117 to 1.258), those exclusively breastfed (OR 0.499, 95% CI 0.222 to 1.51) and those practising good hygienic practices (OR 0.440, 95% CI 0.229 to 0.847). Boys had high odd of girls (OR 6.824, 95% CI 3.543 to 13.143) while children of educated fathers (OR 0.340, 95% CI 0.119 to 0.973), those receiving complementary food at 6 months (OR 0.368, 95% CI 0.148 to 1.393) and those practising good hygiene (OR 0.310, 95% CI 0.153 to 0.631) had lower odds (p<0.05) of being underweight. Boys (OR 3.702, 95% CI 1.537 to 8.916) had higher odds of being wasted, whereas children of educated mothers (OR 0.480, 95% CI 0.319 to 4.660), those from nuclear families (OR 0.356, 95% CI 0.113 to 1.117), those receiving early breast feeding (OR 0.435, 95% CI 0.210 to 1.341) and those practising hand washing (OR 0.290, 95% CI 0.112 to 0.750) had lower odds (p<0.05) of being wasted. CONCLUSION: This study demonstrated the sex of the child, illiteracy of fathers, not practising hand washing and not observing hygiene, late initiation of breast milk, complementary feeding timings, and lack of proper exclusive breast feeding as contributing factors to the under-nutrition of the children in the study population.

The Socio-Environmental Determinants of Childhood Malnutrition: A Spatial and Hierarchical Analysis.

Despite a remarkable reduction in global poverty and famines, substantial childhood malnutrition continues to persist. In 2017, over 50 million and 150 million young children suffered from acute malnutrition (wasting) and chronic malnutrition (stunting), respectively. Yet, the measurable impact of determinants is obscure. We evaluate proposed socio-environmental related determinants of stunting and wasting across Kenya and Nigeria and quantify their effectiveness. We combine health and demographic data from Kenya and Nigeria Demographic Health Surveys (2003, 2008-2009, 2013, 2014) with spatially explicit precipitation, temperature, and vegetation data. Geospatial and disaggregated data help to understand better who is at risk and where to target mitigation efforts. We evaluate the responsiveness of malnutrition indicators using a four-level random intercept hierarchical generalized logit model. We find that spatial and hierarchical relationships explain 28% to 36% of malnutrition outcome variation. Temporal variation in precipitation, temperature, and vegetation corresponds with more than a 50% change in malnutrition rates. Wasting is most impacted by mother's education, family wealth, clinical delivery, and vaccinations. Stunting is most impacted by family wealth, mother's education, clinical delivery, vaccinations, and children asymptomatic of fever, cough, or diarrhea. Remotely monitored climatic variables are powerful determinants, however, their effects are inconsistent across different indicators and locations.

Infant Feeding Practices, Prevalence of Adolescent Motherhood and Malnutrition among Infants in Mangu Local Government Area, Plateau State, Nigeria.

Background: Adolescent motherhood and malnutrition among children are significant challenges in Africa, but there is limited data on the impact of adolescent motherhood on their children's health and nutrition. This study assessed infant feeding practices, prevalence of adolescent motherhood, and malnutrition among infants in Mangu local government area (LGA). Methodology: A cross-sectional survey using multistage sampling was conducted. Validated questionnaires were used to collect socio-demographic data, and appropriate tools were used for anthropometric measurements. Data were compared with established standards. Descriptive statistical tools, chi square, Pearson correlation, and independent sample t-test were used for data analysis, with significance set at p < 0.05. Results: A total of 200 mothers completed the study. The majority of the infants (78.5%) were less than 6 months old, and 21.5% were 6-12 months old. Breastfeeding initiation within 1 hour was reported by 39% of mothers, while 38% practiced prelacteal feeding. Only 28.5% practiced exclusive breastfeeding, and all mothers breastfed their babies. The prevalence of adolescent motherhood was 37.5%. The prevalence of stunting, wasting, and underweight among infants were 29.5%, 12%, and 8.5%, respectively. Children of adolescent mothers had higher rates of severe stunting compared to children of mothers above 19 years of age. There were significant differences (p = 0.017 and p = 0.029) in stunting rates and weight-for-age indices between children of adolescent mothers and mothers above 19 years of age. Conclusion: Adolescent motherhood contributes to chronic malnutrition in children, and there is a high prevalence of malnutrition among infants in Mangu LGA, Plateau State.

Prevalence and associated factors of malnutrition among under-five children living in slum areas of Bahir Dar Town, Ethiopia.

Introduction: child malnutrition is one of the most serious and least addressed health problems in the world and in Ethiopia. The prevalence of malnutrition, underweight, and wasting was 44%, 29%, and 10% respectively. The Amhara region has the highest rates of malnutrition at 52%, 33.4%, and 9.9% for children under five. The aim of this study was to assess the prevalence of malnutrition and its associated factors among children under five living in the slum areas of Bahir Dar City. Methods: a community-based cross-sectional study was conducted with 680 children aged 6-59 months in slum areas of Bahir Dar Town. Study participants were selected using a mass sampling technique and data were collected from April to June 2018 using a pre-tested structured questionnaire and anthropometric measurements. Finally, the collected data were coded, entered, cleaned, recorded, and stored, and the data were processed using EPI INFO and exported to the SPSS version 25.0 statistical package. Logistic regression analysis and interpretation were performed using bivariate and multivariate analysis. Results: a total of 680 children participated. The prevalence of stunting, underweight, and wasting was 46.2% (95% CI; 42.5-49.1), 24.3% (95% CI; 21.2-27.6), and 11.3% (95% CI; CI; 9.2-13.9). Income groups included children [AOR=3.476 (95% CI, 1.959-6.167)], male children [AOR=2.586 (95% CI; 1.532-4.365)] and mother's educational level [(AOR=2.600) (1.623) - 4.164)] were significantly associated with malnutrition. Conclusion: the results of this study showed that the prevalence of malnutrition due to stunting and wasting was high among children under five years of age. The gender of the child, the educational level of the mother, and the monthly income of the family were found to be significantly related to malnutrition. Promoting the use of family planning, preventing diarrheal diseases, and vaccinating children through nutrition education programs are important activities to improve the nutritional status of children.

Assessment of malnutrition using Z-scores and Composite Index of Anthropometric Failure among street children in Delhi.

BACKGROUND: Street children are poverty-stricken and have insufficient money to meet their daily nutritional requirements. They do not have a proper place to sleep and defecate. They sleep at traffic signals, in religious places, and on footpaths. This exposes them to pollution, dirt, and other pathogens. OBJECTIVES: This study aimed to measure the nutritional status of street children in Delhi using Z-scores and Composite Index of Anthropometric Failure (CIAF). METHODS: Anthropometric measurements are direct methods of measuring the nutritional status of humans. Anthropometric indicators such as underweight (weight-for-age), stunting (height-for-age) and BMI/wasting (weight-for-height) are used to measure the nutritional status of street children. Z-scores and CIAF are calculated for street children based on the WHO 2009 reference. RESULTS: According to Z-scores, stunting (56%) is the most common anthropometric failure among street children followed by underweight (31%) and wasting (19%). According to the CIAF, 63% of street children are malnourished, where stunting (37%) is the highest single burden of anthropometric failure, followed by wasting (3%) and underweight (1%); children suffering from the double burden of anthropometric failure are 9%, and children suffering from the triple burden of anthropometric failure (i.e., wasting, stunting, and underweight) are 13%. CONCLUSION: A high incidence of stunting points to poor quality of food and suggests prolonged nutrition deficiency among street children. The Z-score or conventional measures of anthropometry underestimate the total burden of malnutrition among street children, while CIAF provides an estimation of children with single-burden, double-burden, and triple-burden malnutrition or total burden of malnutrition.

Risk Factors of Wasting-Based Malnutrition in the Flood-Affected Areas of Pakistan: A Cross-Sectional Study.

The current study aimed to find the risk factors of wasting in flood-affected areas of Khyber Pakhtunkhwa, Pakistan. Sociodemographic and anthropometric data was collected. Children living in large family are 2.59 times more likely to be wasted (AOR = 2.59, 95% confidence interval (CI): 1.10, 6.10; p value = .029) and children living in medium size family are 2.23 times more likely to be wasted (AOR = 2.23, 95% CI: 1.03, 4.80; p value = .04) as compared to children in small family size. The study underscores the need for targeted interventions to address the identified risk factors and mitigate the impact of flooding on child nutrition.

Prevalence of Wasting and its Associated Factors among Children Under 5 Years of Age in India: Findings from the Comprehensive National Nutrition Survey.

BACKGROUND: The burden of wasting among under five children in India, has not reduced in the last decade. OBJECTIVES: We used child-level data from the latest nationally representative Comprehensive National Nutritional Survey (CNNS) to estimate the prevalence of wasting at the national and state level in India. METHODS: We explored the association of wasting with maternal, child and household factors using multivariable logistic regression for the age group of 0-5, 6-23 and 24-59 months. RESULTS: The overall prevalence of wasting was 17.3%, ranging from 5.8% to 29.1% across states, 23.3% in children 0-5 months, 19.6 % in children 6-23 months and 15.4 % in children 24-59 months of age. Higher birthweight i.e., every 100g increase (0-5 months aOR = 0.96, 6-23 months aOR = 0.94, 24-59 months aOR = 0.96), higher maternal BMI (0-5 months aOR = 0.51, 6-23 months aOR = 0.62, 24-59 months aOR = 0.67), increasing child age in months (0-5 months aOR = 0.84) and female sex of the child (24-59 months aOR = 0.82) was found to have significantly lower odds of wasting. The odds of wasting were significantly higher for poorest wealth quintile (0-5 months aOR = 1.99, 6-23 months aOR = 2.13), maternal unemployment (0-5 months aOR = 2.25), and lower levels of maternal education (6-23 months aOR = 1.74). CONCLUSIONS: Our analyses showed that burden of wasting continues to remain high in India. Preventive interventions must target reduction of low birthweight. Early identification and management of wasting should be done, especially during the first six months of life who are not part of current therapeutic feeding programme.

Weight Velocity in Addition to Latest Weight Does Not Improve the Identification of Wasting or the Prediction of Stunting and Mortality: A Longitudinal Analysis Using Data from Malawi, South Africa, and Pakistan.

BACKGROUND: In low/middle-income countries, most nutritional assessments use the latest weights, without reference to growth trajectory. OBJECTIVES: This study explores whether velocity, in addition to the latest weight, improves the prediction of wasting, stunting, or mortality in the first 2 years of life. METHODS: We analyzed a combined data set with weight and height data collected monthly in the first year of 3447 children from Pakistan, Malawi, and South Africa, with height and survival recorded till 24 m. The main exposures were weight-for-age z-score (WAZ) at the end of each 2-m period and weight velocity-for-age z-score (WVZ2) across that period. The outcomes were wasting, stunting, or all-cause mortality in the next 1-2 mo. As a sensitivity analysis, we also used WVZ over 6 mo (WVZ6), with matching WAZ. Cox proportional hazard models with repeated growth measures were used to study the association between exposures and mortality. Mixed Poisson models were used for stunting and wasting. RESULTS: Children who were already stunted or wasted were most likely to remain so. Higher WVZ2 was associated with a lower risk of subsequent stunting (risk ratio [RR]: 0.95; 95% confidence interval [CI]: 0.93, 0.96), but added minimal prediction (difference in AUC = 0.004) compared with a model including only WAZ. Similarly, lower WVZ2 was associated with wasting (RR: 0.74; 95% CI 0.72, 0.76) but the prediction was only marginally greater than for WAZ (difference in AUC = 0.015). Compared with WAZ, WVZ6 was less predictive for both wasting and stunting. Low WVZ6 (but not WVZ2) was associated with increased mortality (hazard ratios: 0.75, 95% CI: 0.67, 0.85), but added only marginal prediction to a model including WAZ alone (difference in C = 0.015). CONCLUSIONS: The key anthropometric determinant of impending wasting, stunting, and mortality appears to be how far below the normal range the child's weight is, rather than how they reached that position.

Maternal Feeding Practices of Children One to Three Years in Collins Chabane Municipality of South Africa.

The aim was to assess maternal feeding practices of children one to three years. A descriptive observational design was employed. The sample consisted of mothers-child dyads. A validated structured questionnaire was used. Data was analyzed using SPSS version 26.0. The nutrition status of the children at birth indicated 11.6% underweight as compared to the time of the study (7.2%), 7.9% were stunted increased to 38.0%, while wasting decreased from 11.4%-2.4%. Early cessation of breastfeeding and inappropriate complementary feeding practices were the factors influencing growth. The prevalence of underweight and wasting were low while stunting and overweight were high.

Birth weight mediates the association of maternal undernutrition with child undernutrition prevalence in West Africa.

BACKGROUND: Maternal nutritional status before and during pregnancy is an important determinant of foetal health. In West Africa, maternal and child undernutrition remains a major public health problem and it is important to establish the mechanistic pathway linking the two disorders to help address the problem. We therefore assessed the mediating role of low birth weight (LBW) in the relationship of maternal undernutrition with child undernutrition in West Africa. METHODS: We included recent (2010-2019) DHS data from thirteen West African countries. Poisson regression model with robust standard errors was used to assess the relationship between maternal undernutrition (body mass index and anaemia) and child undernutrition (stunting, wasting, underweight, and anaemia). Structural equation modelling was used to conduct the mediation analysis. RESULTS: Prevalence of stunting, wasting, underweight, and anaemia among under-five children in West Africa was found to be 32.4%, 8.1%, 20.1%, and 71.5%, respectively. We found children of underweight mothers to be more likely to be undernourished (stunted, wasted, and underweight) and anaemic compared to children of normal-weight mothers. Also, children of anaemic mothers were more likely to be stunted and anaemic but not wasted compared with children of non-anaemic mothers. LBW mediated the observed relationships between maternal BMI and childhood stunting (22.6%), and maternal anaemia and childhood stunting (24.9%), wasting (11.7), and anaemia (6.6%). CONCLUSION: We found maternal undernutrition to be associated with child undernutrition in West Africa with LBW noted to be a mediator of the observed relationship. We recommend that, to address the child undernutrition problem in West Africa, governments and policymakers must integrate measures to address the burden of LBW.

Neonatal anthropometric indicators of infant growth and mortality in Burkina Faso.

OBJECTIVE: Most evidence supporting screening for undernutrition is for children aged 6-59 months. However, the highest risk of mortality and highest incidence of wasting occurs in the first 6 months of life. We evaluated relationships between neonatal anthropometric indicators, including birth weight, weight-for-age Z-score (WAZ), weight-for-length Z-score (WLZ), length-for-age Z-score (LAZ) and mid-upper arm circumference (MUAC) and mortality and growth at 6 months of age among infants in Burkina Faso. DESIGN: Data arose from a randomised controlled trial evaluating neonatal azithromycin administration for the prevention of child mortality. We evaluated relationships between baseline anthropometric measures and mortality, wasting (WLZ < -2), stunting (LAZ < -2) and underweight (WAZ < -2) at 6 months of age were estimated using logistic regression models adjusted for the child's age and sex. SETTING: Five regions of Burkina Faso. PARTICIPANTS: Infants aged 8-27 d followed until 6 months of age. RESULTS: Of 21 832 infants enrolled in the trial, 7·9 % were low birth weight (<2500 g), 13·3 % were wasted, 7·7 % were stunted and 7·4 % were underweight at enrolment. All anthropometric deficits were associated with mortality by 6 months of age, with WAZ the strongest predictor (WAZ < -2 to ≥ -3 at enrolment v. WAZ ≥ -2: adjusted OR, 3·91, 95 % CI, 2·21, 6·56). Low WAZ was also associated with wasting, stunting, and underweight at 6 months. CONCLUSIONS: Interventions for identifying infants at highest risk of mortality and growth failure should consider WAZ as part of their screening protocol.

Trends in social determinants of inequality in child undernutrition from the Ethiopian Demographic and Health Surveys, 2005-2016.

BACKGROUND: While child undernutrition has been eliminated in some middle-income countries, it remains highly prevalent in sub-Sahara African (SSA) and South Asian regions, and is disproportionately concentrated among the poor. In this study, we estimated trends in child undernutrition by social determinants and related risks from wealth inequality in Ethiopia, from 2005 to 2016. METHOD: We analyzed data from three consecutive surveys (2005, 2011, and 2016) from the Ethiopian Demographic and Health Survey. First, we estimated trends in the prevalence of childhood undernutrition variables (stunting, underweight, and wasting) and social determinants (household wealth status, education level, place of residence, and administrative regions). Then we assessed evidence of undernutrition by wealth-related inequality with concentration curves (visual) and concentration indeces (quantitative). A multilevel mixed-effect Poisson regression model was used to identify predictors of undernutrition variables expressed as covariate-adjusted rate ratios, with 95% confidence intervals (RRs, 95%CI). RESULT: A total of 23,934 mother-child pairs were obtained from the three surveys. The average prevalence decreased by 12.4 percentage points for stunting (from 50.8 to 38.4%, P<0.01), 9.5 percentage points for underweight (33.2% to23.7%, P<0.01), and 2.1 percentage points for wasting (12.2% to10.1%, P<0.01). There was persistent and statistically evidence of wealth inequality in stunting, underweight, and wasting (concentration indeces of -0.2 to -0.04, all P values <0.05). Stunting, underweight, and wasting variables were associated with male sex of the child (RR 0.94, 0.95, 0.85, all P-values <0.01) recent diarrhea (RR 1.18, 1.27, 1.37, all P-values <0.01), secondary education status of the mother (RR 0.66, 0.57, 0.61, all P-values < 0.057), increasing wealth index (richest) (RR 0.73, 0.70, 0.50, all P-values < 0.05), and having no toilet facility (RR 1.16, 1.22, 1.18, all P-values < 0.05). CONCLUSION: Despite the decreased burden of stunting and underweight, the prevalence of wasting remained relatively unchanged in Ethiopia from 2005 to 2016. Moreover, wealth-related inequality in child undernutrition increased for most of the child undernutrition indicators during this period. Social determinants of child undernutrition warrant urgent implementation of strategies to reduce their health impacts in SSA.

Prevalence and factors associated with undernutrition among children under the age of five years in Benin.

BACKGROUND: Benin ranks as one of the countries in the world with an alarmingly high prevalence of stunting, wasting, and underweight in children under five years. However, limited studies have examined the factors associated with the prevalence of these undernutrition indicators among children under five years in the country. This study aimed to fill this research gap by examining the prevalence rates and factors associated with stunting, wasting, and underweight among this specific population of interest. METHODS: This quantitative study utilised data from the most recent Benin Demographic and Health Survey (BDHS) conducted in 2017-18. The survey employed a nationally representative cross-sectional design and utilised a two-stage stratified cluster sampling technique to select participants. The study included a sample of 13,589 children under the age of five years. The main analytical approach employed was binary logistic regression, which was used to explore the associations between undernutrition (the combined outcome variable representing stunting, wasting, and underweight) and various socio-demographic factors. RESULTS: The combined prevalence of stunting, wasting, and underweight among children under five years in Benin during the 2017-18 survey period was 14.95%. Several factors were significantly associated with these indicators of undernutrition, including female gender (AOR = 0.71, 95% CI = 0.59-0.85), birth weight of 4.1 kg and over (AOR = 0.26, 95% CI = 0.14-0.48), multiple births (AOR = 3.22, 95% CI = 2.11-4.91), and a child's experience of diarrhoea (AOR = 1.76, 95% CI = 1.40-2.20). Furthermore, the prevalence of these undernutrition indicators was higher among children whose mothers had lower levels of education (AOR = 0.82, 95% CI = 0.01-0.42) and were unmarried (AOR = 0.67, 95% CI = 0.49-0.93). CONCLUSIONS: This present study confirms that undernutrition rates are elevated in Benin and are closely linked to perinatal factors such as birth weights and multiple births, postnatal health conditions including diarrheal episodes, and socio-demographic determinants such as a child's gender, maternal education level, and marital status. Therefore, there is the need to consider specific modifiable factors, such as low birth weight, episodes of child diarrhoea, and maternal education as priority targets for child nutrition interventions in Benin.

Trend of risk and correlates of under-five child undernutrition in Bangladesh: an analysis based on Bangladesh Demographic and Health Survey data, 2007-2017/2018.

OBJECTIVES: The objectives of this study are to identify the trend of undernutrition risk among under-five children (U5C) in Bangladesh and the trend of its correlates. DESIGN: Multiple cross-sectional data sets from different time points were used. SETTING: Nationally representative Bangladesh Demographic and Health Surveys (BDHSs) were conducted in 2007, 2011, 2014 and 2017/2018. PARTICIPANTS: In the BDHSs, the sample sizes for ever-married women (age: 15-49 years) were 5300 in 2007, 7647 in 2011, 6965 in 2014 and 7902 in 2017/2018. OUTCOMES: Extant indicators of undernutrition (stunted, wasted and underweight) have been considered as the outcome variables. MATERIALS AND METHODS: Descriptive statistics, bivariate analysis and factor loadings from factor analysis have been used to determine the prevalence of undernutrition over the years and find the trend of risk and its correlates. RESULTS: Risks of stunting among the U5C were 41.70%, 40.67%, 36.57% and 31.14%; that of wasting were 16.94%, 15.48%, 14.43% and 8.44%; and that of underweight were 39.79%, 35.80%, 32.45% and 22.46% in 2007, 2011, 2014 and 2017/2018, respectively. From the factor analysis, it has been found that the top five potential correlates of undernutrition are the wealth index, the education of the father and mother, the frequency of antenatal visits during pregnancy, the father's occupation and/or the type of place of residence in the last four consecutive surveys. CONCLUSION: This study helps us gain a better understanding of the impact of the top correlates on child undernutrition. To accelerate the reduction of child undernutrition more by 2030, Government and non-government organisations should focus on improving education and household income-generating activities among poor households and raising awareness among women about the importance of receiving antenatal care during pregnancy.

A systematic review and meta-analysis of the association of dietary diversity with undernutrition in school-aged children.

BACKGROUND: Malnutrition in childhood has lasting consequences; its effects not only last a lifetime but are also passed down from generation to generation such as short stature, school-aged children are the most vulnerable section of the population and require special attention, including nutrition. METHOD: We searched Medline through PubMed, Scopus, and Web of Science to identify all observational studies published before Jun 2022. Observational studies with a pediatric population aged 5-18 years that evaluated risk estimate with 95% confidence intervals the relationship between dietary diversity and undernutrition (wasting, stunting, and thinness) were included. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) were followed. RESULTS: This is a first systematic review and meta-analysis with a total of 20 studies were eligible (n = 18 388). Fourteen data evaluated stunting resulting in a pooled effect size estimated odds ratio of 1.43 (95% CI: 1.08-1.89; p = 0.013). Ten data evaluated Thinness resulting in a pooled effect size estimated odds ratio of 1.10 (95% CI: 0.81-1.49; P = 0.542). Two studies were revealed wasting with a odds ratio of 2.18 (95% CI: 1.41-3.36; p-value < 0.001). CONCLUSION: According to the conclusions of this meta-analysis of cross-sectional studies, inadequate dietary diversity increases the risk of undernutrition in growth linear but not in thinness in school-aged children. The findings of this analysis suggest that initiatives that support improvements to the diversity of children's diets to reduce the risk of undernutrition may be warranted in LMICs.
