AbstractChildhood stunting remains a public health burden worldwide. Although many studies have examined early life and in‐utero risk factors; most have been observational and have used analytic techniques that make inferences limited to population means, thereby obscuring important within‐group variations. This study addressed that important gap. Using data from a birth cohort of Ugandan infants (n = 4528), we applied group‐based trajectory modelling to assess diverse patterns of growth among children from birth to 1‐year old. A multinomial regression model was conducted to understand the relationship between risk factors and observed patterns across groups. We found that the onset of stunting occurred before birth and followed four distinct growth patterns: chronically stunted (Group 1), recovery (Group 2), borderline stunted (Group 3) and normal (Group 4). The average length‐for‐age z‐score (LAZ) at birth was −2.6, −3.9, −0.6 and 0.5 for Groups 1–4, respectively. Although both Groups 1 and 2 were stunted at birth, stunting persisted in Group 1 while children in Group 2 recovered by the fourth month. Group 3 exhibited mild stunting while Group 4 was normal. Wasting and underweight were observed in all groups, with the highest prevalence of underweight in Group 1. Wasting gradually increased among children born already stunted (Groups 1 and 2). This showed the importance of distinguishing children by their growth patterns rather than aggregating them and only comparing population averages against global growth standards. The design of nutrition interventions should consider the differential factors and potential for growth gains relative to different risks within each group.

AbstractIndia accounts for approximately one third of the world's total population of stunted preschoolers. Addressing global undernutrition, therefore, requires an understanding of the determinants of stunting across India's diverse states and districts. We created a district‐level aggregate data set from the recently released 2015–2016 National and Family Health Survey, which covered 601,509 households in 640 districts. We used mapping and descriptive analyses to understand spatial differences in distribution of stunting. We then used population‐weighted regressions to identify stunting determinants and regression‐based decompositions to explain differences between high‐ and low‐stunting districts across India. Stunting prevalence is high (38.4%) and varies considerably across districts (range: 12.4% to 65.1%), with 239 of the 640 districts have stunting levels above 40% and 202 have prevalence of 30–40%. High‐stunting districts are heavily clustered in the north and centre of the country. Differences in stunting prevalence between low and high burden districts were explained by differences in women's low body mass index (19% of the difference), education (12%), children's adequate diet (9%), assets (7%), open defecation (7%), age at marriage (7%), antenatal care (6%), and household size (5%). The decomposition models explained 71% of the observed difference in stunting prevalence. Our findings emphasize the variability in stunting across India, reinforce the multifactorial determinants of stunting, and highlight that interdistrict differences in stunting are strongly explained by a multitude of economic, health, hygiene, and demographic factors. A nationwide focus for stunting prevention is required, while addressing critical determinants district‐by‐district to reduce inequalities and prevalence of childhood stunting.
AbstractHousehold food and water insecurity has been previously associated with adverse health consequences in children. However, these relationships are understudied in middle‐income Latin American populations such as in Ecuador, where a high prevalence of food and water insecurity has been reported. Using cross‐sectional data from 2018 Ecuadorian National Health and Nutrition Survey, we examined the association of household food insecurity (HFI), household water insecurity (HWI), and concurrent HFI‐HWI with diarrhoea, respiratory illness (RI), and stunting in 20,510 children aged ≤59 months. HFI was measured using the Food Insecurity Experience Scale. HWI was defined when households responded negatively to one or more of four drinking water indicators. Maternal caregivers reported on child diarrhoea and RI episodes during the previous 2 weeks. Measured length or height was used to assess stunting. We constructed log‐binomial regression models to estimate the associations of HFI, HWI, and concurrent HFI‐HWI with child outcomes. Moderate‐severe HFI was associated with a higher prevalence of diarrhoea (PR = 1.39; 95% CI: 1.18, 1.63) and RI (PR = 1.34; 95% CI: 1.22, 1.47), HWI with a higher prevalence of RI (PR = 1.13; 95% CI: 1.04, 1.22), and concurrent HFI‐HWI with a higher prevalence of diarrhoea (PR = 1.30; 95% CI: 1.05, 1.62) and RI (PR = 1.45; 95% CI: 1.29, 1.62). Stunting was not associated with HFI, HWI nor concurrent HFI‐HWI. These findings suggest that HFI and HWI can independently and jointly act to negatively affect children's health. Policies and interventions aimed at alleviating both food and water insecurity are needed to bring sustained health improvements in Ecuadorian children.

ABSTRACT One of the major sources of public health concern in many developing countries is child stunting, which accounts for more than a third of all deaths of children below the age of 5 years worldwide. Although child stunting generally seems to be on a downward trend in the country, the present prevalence is still very high based on international standards. Several studies have established that the extent of early childhood dietary exposure to aflatoxins (AFs) and fumonisins (FBs) in the country occurs through complementary feeding. However, there is a paucity of information on whether this is linked to child stunting. This review discusses child stunting and nutrition and strives to draw a link between early childhood dietary exposure to AFs and FBs and child stunting in Tanzania. The review further outlines the mechanisms of mycotoxin‐induced growth impairment and deliberates on the past, present, and future interventions that can be useful in alleviating the problem of stunting that is linked to these mycotoxins. Such information can be crucial for developing and adopting appropriate interventions that can contribute to the further reduction of child stunting in Tanzania.
Background: Stunting is a significant global health issue, especially in Indonesia, where long-term malnutrition adversely affects children's growth and development, with prevalence rates still exceeding the WHO's recommended threshold. This study examines the contextual factors that influence the effectiveness of nutritional interventions and antenatal care (ANC) in combating stunting in Indonesia. Methods: A systematic review was conducted by the PRISMA guidelines. A comprehensive search across five major academic databases (Google Scholar, PubMed, ScienceDirect, Embase, and ProQuest) identified 3,690 articles. After a rigorous screening process, 13 studies published between 2019 and 2023 were included in the analysis, focusing on key contextual factors that impact stunting interventions in Indonesia. The quality appraisal utilized Joanna Briggs Institute checklists for analytical cross-sectional studies, cohort studies, quasi-experimental studies, qualitative research, systematic reviews, case reports, and text and opinion papers, each matched to the respective study design. Findings: The review identified four critical contextual factors shaping stunting interventions: (1) socioeconomic status, particularly household income and education, which significantly influence access to healthcare and nutrition; (2) cultural beliefs, including food taboos and misconceptions, which hinder optimal nutritional practices; (3) geographical disparities, with rural populations experiencing higher stunting rates due to limited access to healthcare and resources; and (4) government policies, highlighting the importance of strong political commitment, multisectoral collaboration, and localized programs. Conclusion: Nutritional interventions and ANC are more effective in reducing stunting among Indonesian children when tailored to local socioeconomic, cultural, and geographical contexts. These findings highlight the need for targeted, context-specific strategies to improve child growth outcomes in vulnerable populations.

Globally, the prevalence of child stunting is almost the same for both sexes. However, in developing countries, boys are more likely to be shorter than the norm for their age and sex. In sub-Saharan Africa, there is a need to understand this widespread phenomenon in order to help reduce the high prevalence and low decreasing level of stunting observed, in comparison to other parts of the world. In this perspective, we used pooled data from the demographic and health surveys conducted in twenty sub-Saharan countries. On the basis of 134,814 children under the age of five years with a valid anthropometric index constituted, the prevalence of child stunting obtained is 33.4%, with 35.4% (CI=[34.7%; 36.1%]) for boys and 31.3% (CI=[30.6%; 32.0%]) for girls; the largest gender gaps are found in the Great Lakes countries (Rwanda (8.1 points) and Burundi (8.9 points)). It appears that the gender gap in stunting in sub-Saharan Africa is more related to the size of the child at birth, the number of siblings, the birth assistance and wasting. Intensified action on these modifiable factors could help to reduce the observed gender differences and ultimately improve the overall nutritional status of children.
AbstractManagement of undernourished children depends only on wasting yet it can coexist with underweight and/or stunting. Among children admitted to hospital with acute illness, we determined the proportion with wasting coexisting with underweight and/or stunting and their risk factors. A retrospective review of hospital records of children 6‒59 months old admitted at Garissa County referral hospital, Kenya, from January 2017 to December 2019 was conducted. Using World Health Organization 2006 growth standards, undernutrition were defined: wasting as Weight‐for‐height Z‐score < −2, stunting Height‐for‐age Z‐score < −2 and underweight Weight‐for‐age Z‐score < −2. We studied wasting coexisting with underweight and/or stunting. Among 624 children recruited, 347 (56%) were males and 511 (82%) <24 months old. Diarrhoea 210 (34%) and pallor/anaemia 310 (50%) were the most frequent admission diagnosis. HIV infection was present among 8 (1.3%) children. Wasting, underweight and stunting were present among 595 (95%), 518 (83%) and 176 (28%) children respectively. 161 (26%), 506 (81%) and 161 (26%) children had wasting coexisting with stunting, underweight and both stunting and underweight respectively. In the multivariable regression, diarrhoea was positively associated with wasting coexisting with stunting (adjusted risk ratio [aRR = 2.96] [95% CI = 2.06‒4.23]) and anaemia with wasting coexisting with underweight (aRR = 1.23) (95% CI = 1.03‒1.47). Overall, 343 (55%) children were discharged alive, 67 (11%) absconded from the wards, 164 (26%) were transferred to another hospital and 50 (8.0%) died before discharge. The risk of inpatient death was 10.3%, 7.9%, 8.4% and 6.8% among children not wasted, wasted only, wasted & underweight, and wasted and underweight and stunted respectively (Chi‐square p = 0.60). The study reports an unacceptably high levels of undernourishment, including coexisting forms of undernutrition among hospitalised children. This highlights a public health priority for current nutrition therapeutic care and need of continuity of care among those children discharged alive in the community‐based management of acute malnutrition programmes.
AbstractMany low‐ and middle‐income countries are faced with a double burden of malnutrition characterized by a stagnating burden of undernutrition and an increasing prevalence of overweight and obesity often observed both at population and household levels. We used data from the 2017 National Integrated Child Health and Nutrition Survey in the Republic of the Marshall Islands to explore the prevalence of overweight mother‐stunted child pairs (mother–child double burden, MCDB). We used bivariate analysis, multivariate logistic regression, and multinomial logistic regression analysis to explore associations between child‐, maternal‐, and household‐level variables and both stunting and MCDB and other types of maternal–child pairs. Our results indicate that nearly three out of four mothers were overweight or obese and one in four households is home to an overweight mother with a stunted child. The risk of child stunting and of MCDB were largely associated with maternal characteristics of lower maternal height, maternal age at birth, years of education, and marital status and household economic status as measured by wealth index and number of household members. These findings support the growing body of evidence showing that the coexistence of high maternal overweight and child stunting (MCDB) has linked root causes to early life undernutrition that are exacerbated by the nutrition transition.

ABSTRACT Childhood stunting remains a public health challenge in Thailand. While national surveys provide prevalence estimates, there is limited understanding of the multilevel influences shaping child feeding practices. This qualitative study aimed to explore individual, familial, and socioenvironmental determinants of child feeding practices among Thai female caregivers of young children with stunting. In‐depth interviews, guided by Social Cognitive Theory, were conducted with 40 female caregivers (primarily mothers) of children under 5 years old with stunting. Participants were purposively selected from nutrition clinics in four hospitals across four regions of Thailand (Chiang Mai, Bangkok, Satun, and Ubon Ratchathani). Trained local dietitians and nutritionists conducted interviews within the clinics. Transcripts were thematically analysed by two independent researchers, triangulated by input from local interviewers. Children's age ranged from 1.0 to 4.9 years old (mean 3.0 ± 1.1 years). Results showed that caregivers understood the importance of healthful feeding but faced barriers such as financial constraints, low self‐efficacy, limited food acceptance, and misconceptions about nutrition. Permissive feeding practices were common due to concerns over picky eating. Family dynamics, food access and availability, and limited engagement with government nutrition programmes further shaped child feeding practices. This study highlights the complex interplay of multilevel factors that influence child feeding practices among Thai caregivers of young children with stunting. Addressing these challenges effectively requires a multifaceted approach for caregivers, including nutrition education, behavioural support, and policies to improve food access and affordability.

AbstractMany children in low‐ and middle‐income countries are not attaining their developmental potential. Stunting is associated with poor child development, but it is not known which correlates of stunting are impairing child development. We explored potential socioeconomic, nutritional, clinical, and household correlates of early child development among 12–59‐month‐old children with stunting in a cross‐sectional study in Uganda. Development was assessed using the Malawi Development Assessment Tool (MDAT) across four domains of gross and fine motor, language, and social skills. Linear regression analysis was used to assess correlates of development in the four domains and total MDAT score. Of 750 children included, the median [interquartile range] age was 30 [23−41] months, 55% of the children resided in rural settings with 21% from female‐headed households and 47% of mothers had no schooling. The mean ± standard deviation height‐for‐age z‐score (HAZ) was −3.02 ± 0.74, 40% of the children had a positive malaria test and 65% were anaemic (haemoglobin < 110 g/L). One‐third had children's books at home, majority (96%) used household objects to play with and most of them (70%) used toys as pretence items like those to mimic cooking. After age, sex, and site adjustments, HAZ (0.24, 95% confidence interval [CI]: 0.14−0.33) and head circumference (0.07, 95% CI: 0.02−0.12) were positive correlates of total MDAT score, whereas weight‐for‐height z‐score (WHZ) was not. Current breastfeeding was associated with 0.41 (95% CI: 0.17−0.65) lower total MDAT score. Children from households with a single income earner had 0.22 (95% CI: 0.06−0.37) lower total MDAT score. Furthermore, severe food insecurity, inflammation and positive malaria test were associated with lower scores for motor development. All family care indicator subscales (FCIs) positively correlated with the total MDAT score and this association was independent of household's socioeconomic status. In conclusion, stunting degree, head circumference, number of household income earners and stimulation by improved FCIs correlate with early child development among stunted children. The negative association with prolonged breastfeeding is likely due to reverse causality. Identified correlates may inform initiatives to support children with stunting attain their development potential.
