Prevalence and associated factors of adolescent undernutrition in Ethiopia: a systematic review and meta-analysis

The magnitude of stunting and its determinants among late adolescent girls in East Africa: Multilevel binary logistics regression analysis

BACKGROUND

Stunting poses a significant health risk to adolescent girls aged 15-19 in low- and middle-income countries, leading to lower education levels, reduced productivity, increased disease vulnerability, and intergenerational malnutrition. Despite the inclusion of adolescent nutrition services in the Sustainable Development Goals, little progress has been made in addressing malnutrition among adolescent girls in several African nations. Limited evidence exists in East Africa due to small sample sizes and methodological limitations. To overcome these constraints, this study utilizes the latest Demographic and Health Survey data to estimate the prevalence and factors influencing stunting among late adolescent girls in ten East African countries.

METHODS

This study utilized the most recent Demographic and Health Survey (DHS) data from 10 East African countries, including a total sample weight of 22,504 late-adolescent girls. A multilevel mixed-effect binary logistic regression model with cluster-level random effects was employed to identify factors associated with stunting among these girls. The odds ratio, along with the 95% confidence interval, was calculated to determine individual and community-level factors related to stunting. A p-value less than 0.05 was considered statistically significant in determining the factors influencing stunting among late-adolescent girls.

RESULTS

The prevalence of stunting among late adolescent girls in East Africa was found to be 13.90% (95% CI: 0.13-0.14). Religion, relationship to the head, presence of under-five children in the household, lactating adolescent, marital status, Time to get water source, and country of residence were significantly associated with Stunting.

CONCLUSION

This study highlights the complexity of stunting in East Africa and identifies key factors that need attention to reduce its prevalence. Interventions should focus on improving water access, supporting lactating girls, addressing socioeconomic disparities, promoting optimal care practices, and implementing country-specific interventions to combat stunting and improve adolescent girls' nutrition.

Diet quality and snack preferences of Turkish adolescents in private and public schools

Introduction

Socioeconomic level is one of the important factors determining diet quality. Snack preferences are affected by socioeconomic level. The objective of this research was to determine the effect of socioeconomic levels on diet quality and snack preferences among adolescents from different socioeconomic backgrounds.

Methods

The study involved 118 adolescents aged between 10-18 years residing in Istanbul. A questionnaire prepared by the researchers was used to obtain information on the adolescents' dietary habits, consumption of main meals and snacks, habits, and food consumption records. The participants' food consumption was assessed using the retrospective 24-hour recall method, and diet quality was evaluated using the calculated nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR).

Results

The mean age of the adolescents was 16.42±0.89 years. The number of snacks consumed in private schools was found to be higher than in public schools (p < 0.05). The NAR score for vitamin C consumption was significantly higher in private schools compared to public schools (p < 0.05). Although the MAR scores of adolescents in private schools were higher than those in public schools, this difference was not statistically significant. The majority of adolescents in private schools regularly consumed fresh fruit (67.2%), milk (60.3%), yogurt (60.3%), and nuts (56.9%) as snacks. In contrast, 45% of adolescents in public schools regularly consumed pastries (p < 0.05).

Discussion

It was observed that adolescents studying in public schools had a lower tendency to prefer healthy foods for snacks compared to those in private schools. Socioeconomic level was identified as an important factor influencing eating habits during adolescence. Considering that the level of income is significantly different between the adolescents studying at private and public schools, the higher consumption of snacks by the adolescents studying at private school may be associated with higher income.

Decreased Weight-for-Age Associated with Mass Deworming among Young Ethiopian Schoolchildren in Jimma Town, Southwest Ethiopia: A School-Based Cross-Sectional Study

School-based mass deworming programs are implemented to reduce soil-transmitted helminth (STH) infection prevalence and intensity among school-aged children. However, previous studies debate the impact of deworming beyond the removal of worms. Hence, this study aimed to examine the effect of mass deworming on nutritional indicators in young Ethiopian schoolchildren. A school-based cross-sectional study was conducted among 1,036 participants from April to May 2020 in Jimma Town, Ethiopia. An interviewer-based questionnaire was administered to the children to gather data on sociodemographic, lifestyle variables, and deworming status. Anthropometric measurements were taken for the height and weight of the children. Stool samples were collected and analyzed for STH infection using direct wet mount microscopy and the Kato-Katz technique. In multivariate logistic regression analysis, deworming within the past 6 months or 1 year was not significantly associated with underweight, stunting, and thinning. However, deworming within the past year was significantly associated with decreased weight-for-age z-score (adjusted mean difference = -0.245; 95% CI: -0.413 to -0.076; P = 0.004). Deworming in the past 6 months demonstrated a nonsignificant trend toward increased stunting (adjusted odds ratio = 1.258; 95% CI: 0.923-1.714; P = 0.145). This study provides evidence that deworming in the past 6 months or 1 year was not significantly associated with underweight, stunting, and thinning. However, deworming within the past year was associated with a significantly decreased weight-for-age z-score in young Ethiopian schoolchildren of Jimma Town after adjustment for confounding variables.

Prevalence and associated factors of stunting and thinness among adolescent Sudanese schoolchildren: a cross-sectional study

BACKGROUND

Malnutrition among adolescents is a considerable health problem worldwide. There are scarce data on undernutrition among adolescents in Sudan.

METHODS

A cross‑sectional study was conducted to investigate the prevalence and associated factors of stunting and thinness among adolescent schoolchildren in northern Sudan. The questionnaires were used to collect information on sociodemographics. Weights and heights were measured and the height-for-age and body mass index-for-age cut-offs recommended by the WHO were applied, followed by logistic regression analysis.

RESULTS

Of 384 enrolled adolescents, 202 (52.6%) were females and 182 (47.4%) were males. The median (IQR) age of these adolescents was 15.1 (14.0‒16.3) y. Seventy-six (19.8%) and 52 (15.4%) adolescents had stunting and thinness, respectively, and 15 (3.9%) had both stunting and thinness. Multivariate analysis showed that increased age (adjusted OR [AOR]=1.30, 95% CI 1.08 to 1.57) and male gender (AOR=5.82, 95% CI 3.11 to 10.91) were associated with stunting. Male gender (AOR=2.08, 95% CI 1.14 to 3.82) and smoking/tobacco snuff (AOR=2.61, 95% CI 1.07 to 6.36) were associated with thinness.

CONCLUSIONS

The findings of the current study are that both stunting and thinness are important health problems, especially among boys, older participants and smokers.

Dietary patterns in relation with nutritional outcomes and associated factors among adolescents: implications for context-specific dietary intervention for the Agrarian Community, Northwest Ethiopia

Introduction

Dietary pattern analysis allows us to characterize the dietary intakes of individuals rather than nutrient intake data and strongly predicts disease risks. The relationship between food intake and adolescents' nutritional health is not well understood yet. Therefore, this study aimed to generate evidence for context-specific dietary intervention for adolescents.

Objective

This study aimed to determine dietary patterns and their relationship with nutritional outcomes and identify the contributing factors among adolescents in the Agrarian Community of Northwest Ethiopia.

Methods

A cross-sectional survey was conducted among 622 randomly selected adolescents. Dietary data were collected over a 1-week recall period using the Food Frequency Questionnaire (FFQ). After testing the basic assumptions, an exploratory factor analysis was conducted to determine the dietary patterns. Anthropometric data on weight and height were collected to determine the nutritional status using WHO Anthroplus 2010 software. A chi-square test was conducted to evaluate the effect of different dietary patterns on nutritional outcomes. A multivariable binary logistic regression model was used to identify factors affecting the dietary patterns of adolescents.

Result

Three types of dietary patterns, namely, traditional, mixed, and animal-source foods with traditional alcoholic beverage consumption were identified. These dietary patterns explain 58.64% of the variance in adolescent diet in the study setting. The burden of stunting was 15.12% vs. 11.21, 19.40% vs. 6.94, and 8.36% vs.17.97% among adolescents with lower traditional, mixed, and higher animal sources with alcoholic dietary pattern consumption habits, respectively (value of p <0.05). Adolescents who resided in low-land agroecology (AOR = 2.44; 95% CL: 1.24, 4.81) and had access to animal-source foods (AOR = 1.64; 95% CI: 1.04, 2.60) were associated with lower consumption of traditional dietary patterns. Similarly, adolescents who resided in low-land (AOR = 1.80; 95% CI: 1.18, 2.74) had formal education (AOR = 2.38; 95% CI: 1.35, 4.19) and had poor nutrition knowledge (AOR = 2.83; 95% CL: 1.55, 5.19) were associated with lower consumption of mixed dietary patterns. Moreover, adolescents residing in the high-land (AOR = 2.50; 95% CI: 1.37, 4.56) and being female (AOR =1.87; 95% CI: 1.27, 2.74) were significant factors associated with lower consumption of animal-sourced foods with traditional alcoholic beverage consumption patterns.

Conclusion

Multidimensional modifiable factors were explored that could be targeted for public health interventions for the identified dietary patterns. Integrated and multifaceted dietary intervention approaches are needed to promote healthy diets and discourage the consumption of unhealthy diets to reduce undernutrition in the study area and similar settings.

Feasibility and impact of school-based nutrition education interventions on the diets of adolescent girls in Ethiopia: a non-masked, cluster-randomised, controlled trial

BACKGROUND

Adolescence is a critical period of physical and psychological development, especially for girls, because poor nutrition can affect their wellbeing as well as that of their children. We aimed to assess the feasibility and impact of a package of nutrition education interventions delivered through public primary schools on the diets of adolescent girls in Ethiopia.

METHODS

In this non-masked, cluster-randomised, controlled trial, primary schools (clusters) in the Southern Nations, Nationalities, and People's Region and Somali region of Ethiopia were randomly allocated to the intervention group (nutrition information provided during flag ceremonies, classroom lessons, school club meetings, peer group mentoring, BMI measurement and counselling, and parent-teacher meetings) or the control group (standard academic curriculum on health and nutrition) by use of computer-generated pseudo-random numbers. Duration of the school-based interventions was 4 months, and the key messages were related to dietary diversity (eating a variety of foods), energy adequacy (eating breakfast and healthy snacks), and healthy food choices (avoiding junk foods). Adolescent girls were eligible for participation if aged 10-14 years and enrolled in grades 4-8 in a study school. Data were collected with two independent cross-sectional surveys: baseline before the start of implementation and endline 1·5 years later. The primary outcome of impact was dietary diversity score, defined as the number of food groups (out of ten) consumed over the previous 24 h using a list-based method, and minimum dietary diversity, defined as the proportion of girls who consumed foods from at least five of the ten food groups, in the intention-to-treat population. We also assessed intervention exposure as a measure of feasibility. We estimated intervention effects using linear regression models for mean differences at endline, with SEs clustered at the school level, and controlled for adolescent age, region, household food security, and wealth. The trial is registered with ClinicalTrials.Gov, NCT04121559, and is complete.

FINDINGS

27 primary schools were randomly allocated to the intervention group and 27 to the control group. Between March 22 and April 29, 2021, 536 adolescent girls participated in the endline survey (270 in the intervention group and 266 in the control group), with median age of 13·3 years (IQR 12·1-14·0). At endline, the dietary diversity score was 5·37 (SD 1·66) food groups in the intervention group and 3·98 (1·43) food groups in the control group (adjusted mean difference 1·33, 95% CI 0·90-1·75, p<0·0001). Increased minimum dietary diversity was also associated with the intervention (182 [67%] of 270 in the intervention group vs 76 [29%] of 266 in the control group; adjusted odds ratio 5·37 [95% CI 3·04-9·50], p<0·0001). 256 (95%) of 270 adolescent girls in the intervention group were exposed to at least one of the five in-school intervention components.

INTERPRETATION

Integrating nutrition interventions into primary schools in Ethiopia was feasible and increased dietary diversity incrementally among adolescent girls, but could be limited in changing other food choice behaviours, such as junk food consumption, based on nutrition education alone.

The prevalence of undernutrition among students attending traditional Ethiopian orthodox Tewahedo church schools in northwest Ethiopia

Background

Undernutrition is a major public health concern affecting the health, growth, development, and academic performance of adolescents studying in school. During this crucial period, dietary patterns have a vital impact on lifetime nutritional status and health. The problem of undernutrition among particular groups of adolescents attending traditional schools has not previously been studied. Therefore, this study aimed to assess the prevalence of undernutrition and associated factors among adolescents aged 10-19 years attending Orthodox Church schools in northwest Ethiopia.

Methods

An institution-based, cross-sectional study design was employed, with data collected from March 1 to 30, 2021. A simple random sampling technique was used to recruit a total of 848 male attendees of traditional schools. Data were collected via an interviewer-administered semi-structured questionnaire. The nutritional status of participants was assessed using anthropometric measurements. The WHO Anthroplus software was used for analysis. Both bivariable and multivariable logistic regression analyses were conducted to identify the factors associated with nutritional status. The degree of association between the independent variables and the dependent variable was assessed using odds ratios, reported with 95% confidence intervals, and a threshold of p ≤ 0.05.

Results

The prevalence of undernutrition was found to be 61.3% [95% CI: 58.1, 64.6]. The likelihood of developing undernutrition was elevated among those adolescents who were following the traditional school levels of dikuna (AOR = 4.3, 95% CI = 1.3, 13.6), kinne (AOR = 4.5, 95% CI = 1.4, 14.6), aquaquame (AOR = 9.9, 95% CI = 2.5, 39.88), tirguame (AOR = 6.4, 95% CI = 1.6, 25.6), and among those whose mothers had no formal education [AOR = 3.7, 95% CI: 1.2, 12.8]. In contrast, those adolescents who always washed their hands after a toilet visit had lower odds of undernutrition than their counterparts [AOR = 0.7, 95%CI: 0.5, 0.98].

Conclusion

More than three out of five participating male adolescents were undernourished. Thus, to improve the nutritional status of adolescents studying in traditional church schools, extensive health education for these adolescents is essential. Moreover, the establishment of well-resourced traditional religious school, equipped for the provision of an adequate, diversified diet, is important. Developing the habit of handwashing after visiting the toilet and before and after food preparation is also recommended for adolescent students.

Prevalence and correlates of stunting and thinness among adolescent students in Lideta subcity, Addis Ababa, Ethiopia: a cross-sectional study

OBJECTIVES

To determine the prevalence of stunting and thinness and associated factors among adolescents attending public schools in Lideta subcity, Addis Ababa, Ethiopia, in 2021.

DESIGN

Cross-sectional.

SETTING

Public schools in Lideta subcity, Addis Ababa, Ethiopia.

ELIGIBILITY

Adolescents from grades 5-12 in public schools and students whose parents gave consent for participation.

DATA ANALYSIS

Bivariate and multivariable logistic regression analyses were used to examine the association between the independent variables and stunting and thinness. Using a 95% CI and adjusted OR (AOR), factors with a p value of less than 0.05 were determined to have a significant association.

OUTCOME MEASURES

The prevalence of stunting and thinness, as well as the factors associated with stunting and thinness, were secondary outcomes.

RESULTS

The overall prevalence of stunting and thinness was 7.2% (95% CI: 5.3% to 9.3%) and 9% (95% CI: 6.8% to 11.4%), respectively. Stunting was associated with a larger family size (AOR=3.76; 95% CI: 1.58 to 8.94), low dietary diversity (AOR=2.87; 95% CI: 1.44 to 5.74), food insecurity (AOR=2.81; 95% CI: 1.38 to 5.71) and a lower wealth index (AOR=3.34; 95% CI: 1.51 to 7.41). On the other hand, thinness was associated with maternal education in those who were unable to read and write (AOR=2.5; 95% CI: 1.97 to 8.11), inadequate dietary diversity (AOR=4.81; 95% CI: 2.55 to 9.07) and larger family size (AOR=2.46; 95% CI: 1.14 to 5.29).

CONCLUSION

Adolescent stunting and thinness were common in Addis Ababa's public schools. Family size, dietary diversity and food security were the main factors associated with both thinness and stunting. Therefore, to solve the problem of adolescent stunting and thinness, the administration of Addis Ababa city should prioritise minimising food insecurity while boosting productivity to enhance adolescent nutritional diversity. Moreover, nutritional education should be strengthened by healthcare providers working at public schools as well as health extension workers.

Effect of Buffalo Milk Consumption on the Growth of 10 to 12 years Old Schoolgirls in Magdalena, Laguna, Philippines

Background

Milk contains essential nutrients that help can improve the growth and development of adolescent girls.

Objectives

The study determined the effect of milk consumption on the nutritional status of schoolgirls ages 10 to 12 years old in Magdalena, Laguna, Philippines.

Methodology

A quasi-experimental study design was used to determine the impact of daily consumption of 200 ml buffalo milk on the prevalence of undernutrition among the 57 schoolgirl participants before and after 160 days. One sample t-test and paired t-test were used to compare the actual and expected total increment and monthly changes in the height and body mass index (BMI) of the participants, while a one-way analysis of variance was used to compare the actual total changes in height and BMI by age. Factors that are correlated with these measurements were identified based on Spearman's correlation coefficients.

Results

The percentage of stunting (31.6%-22.8%) and thinness (21.1%-15.8%) decreased after the milk feeding. Significant differences were observed in the means of total actual and expected changes in height (P < .00) and BMI (P < .00). While there were significant differences in the means of actual and expected monthly changes in height every month, this was only observed in the first 2 months for BMI. Only the mean actual changes in height had significant differences when compared by age (P = .04). Lastly, the age and education of the father were found to be correlated with the height of the schoolgirls.

Conclusion

Buffalo milk consumption can improve the growth outcomes of schoolgirls.

Prevalence and factors associated with malnutrition among school adolescents of Durame Town, Kambeta Tembaro Zone, Ethiopia

Introduction

malnutrition is a major public health issue affecting adolescents globally and developing countries in particular. Adolescent period is very sensitive to malnutrition. Adolescent malnutrition can be affected by different factors. The objective of this study was to assess prevalence and associated factors of adolescent malnutrition among high school students.

Methods

an institutional-based cross-sectional study was carried out among school adolescents in Durame town high schools. Of the 498 selected school adolescents, 455 (91.4 %) were included in this study. Data were entered into Epi data and exported to World Health Organization (WHO) Anthroplus and Statistical package for the social sciences (SPSS). Odds ratio at 95% confidence interval (CI) was calculated to check for the existence and strength of association between variables. P-value less than 0.05 was used to declare significance of association.

Results

the prevalence of stunting, thinness and overweight among adolescents was 26 (5.7%), 11(2.4 %) and 42 (9.2%), respectively. Residing in rural (AOR=5.31, 95% CI: 1.03-27.27) and utilize community based nutrition (AOR=0.26, 95% CI: 0.07-0.98) were associated with thinness. Male (AOR=3.55, 95% CI: 1.62-7.81) and having cattle (AOR=2.78, 95% CI: 1.393, 5.565) were associated with overweight.

Conclusion

around two in twenty-five adolescents are stunted. About one in twenty-five adolescents are thin. More than two in twenty-five adolescents are overweight. Sex of adolescents, having cattle were associated with overweight of adolescent. Rural residence and utilizing community based nutrition were associated with thinness. Minister of Health and other health offices should implement nutrition education to school adolescents by giving emphasis on place of residence and for both male and female adolescents.

Factors Influencing Undernutrition among Female Adolescent Students in Darchula District, Nepal

Failure to understand and address the problem of malnutrition and its associated factors among female adolescents could lead to a vicious cycle of intergenerational malnutrition. A cross-sectional study was conducted in six secondary schools of four rural municipalities in Darchula District, Nepal. Data collection for the study was conducted from November 2021 to February 2022. Four hundred female adolescent students aged 15 to 19 years old were selected using quota sampling. The study aims to examine the prevalence of malnutrition by assessing different levels of body mass index (BMI) that is thinness (BMI less than 18.5 kg/m2), normal (18.5 kg/m2 to 24.9 kg/m2), overweight (25 kg/m2 to 29.9 kg/m2) and obese (BMI more than or equal to 30 kg/m2). Along with BMI, factors associated with undernutrition, here identified as thinness, are assessed using a structured questionnaire. Additionally, key informant interviews and review of interventions was performed to understand the gaps in nutrition-related policies and programs of school going adolescents in the study district. Quantitative data analysis included a prevalence study and chi-square test along with simple and multiple logistic regression to obtain crude and adjusted odds ratio at 95% confidence interval for the significant factors with p < 0.05 identified in the chi-square test. Thematic analysis and reviews were used for the synthesis of qualitative data. The results show a 24.7% prevalence of thinness in the study participants. Pre-mensuration status (OR = 5.015, CI = 1.257–20.011, p < 0.022), father having a monthly paying job (OR = 4.384, CI = 1.135–16.928, p < 0.032), father’s foreign employment (OR = 6.96, CI = 1.649–29.377, p < 0.008), household (HH) food insecurity status (OR = 2.079, CI = 1.182–3.658, p < 0.011) and grain/roots/tuber as most commonly bought food (OR = 9.487, CI = 1.182–76.138, p < 0.034) were found to be significantly associated with thinness. Information from the qualitative part identified gaps in existing interventions for an improved nutritional outcome among school going adolescent females. Further studies to understand the nutritional practices and its contributory factors in relation to thinness is encouraged. Stakeholders are urged to effectively address the shortcomings in existing interventions and adopt a more adolescent-centered approach to enhance the nutritional status of female adolescents.

A nutritional supplement containing zinc during preconception and pregnancy increases human milk zinc concentrations

Introduction

During pregnancy and lactation minerals such as zinc are required to support maternal and infant health. Zinc is involved in various cellular processes, with requirements increasing in pregnancy and lactation. In the setting of a randomized trial, we investigated the effects on human milk (HM) zinc concentrations of a micronutrient-containing supplement including zinc in the intervention (but not control) group, started preconception and taken throughout pregnancy until birth. Additionally, we characterized longitudinal changes in HM concentrations of zinc and other minerals (calcium, copper, iodine, iron, magnesium, manganese, phosphorus, potassium, selenium, and sodium).

Methods

HM samples were collected across 7 time points from 1 week to 12 months from lactating mothers from Singapore (n = 158) and New Zealand (n = 180). HM minerals were quantified using sector field inductively coupled plasma mass spectrometry. Potential intervention effects on HM mineral concentrations were assessed using linear mixed models with a repeated measures design and time-weighted area-under-the-curve analyses.

Results

Over the first 3 months of lactation, HM zinc concentrations were 11% higher in the intervention group compared to the control group (p = 0.021). Higher HM zinc concentrations were most evident at 6 weeks of lactation. The intervention had no effect on HM concentrations of other minerals, which were not differently supplemented to the control and intervention groups. Temporal changes in HM minerals over 12 months of lactation were studied in the New Zealand mothers; HM zinc and copper concentrations progressively decreased throughout 12 months, while iron, potassium, sodium, and phosphorus decreased until 6 months then plateaued. HM calcium and magnesium initially increased in early lactation and iodine remained relatively constant throughout 12 months. HM manganese and selenium fell over the initial months of lactation, with a nadir at 6 months, and increased thereafter. The contrasting patterns of changes in HM mineral concentrations during lactation may reflect different absorption needs and roles at different stages of infancy.

Discussion

Overall, this study indicates that HM zinc concentrations are influenced by maternal supplementation during preconception and pregnancy. Further studies are required to understand the associations between HM zinc and other minerals and both short- and long-term offspring outcomes.

Multilevel analysis of undernutrition and associated factors among adolescent girls and young women in Ethiopia

Background

The consequences of undernutrition have serious implication for the health and future reproductive periods of adolescent girls and young women aged 15–24 years. Inspite of this, they are neglected age groups and there is limited information about the nutritional status of this age group in Ethiopia. Therefore, estimating the extent and associated factors of undernutrition among adolescent girls and young women in a national context using multilevel analysis is essential.

Methods

Secondary data analysis was conducted from the Ethiopian Demographic and Health Survey 2016. A total sample weight of 5362 adolescent girls and young women was included in this study. A multilevel mixed-effect binary logistic regression model with cluster-level random effects was fitted to determine the associated factors of undernutrition among adolescent girls and young women in Ethiopia. Finally, the odds ratios along with the 95% confidence interval was generated to determine the individual and community level factors of undernutrition. A p-value less than 0.05 was declared as the level of statistical significance.

Results

Overall, 25.6% (95%CI: 24.5–26.9) of adolescent girls and young women were undernourished. Statistically significant individual level factors includes adolescent girls and young women aged 15–19 years (AOR: 1.53, 95%CI: 1.32–1.77), individual media exposure (AOR: 0.82, 95%CI: 0.69–0.97), and unprotected drinking water source (AOR: 1.24, 95%CI: 1.04–1.48). Whereas, Southern Nations, Nationalities, and Peoples' Region (AOR: 0.33, 95%CI: 0.13–0.83) and rural residence (AOR: 1.69, 95%CI: 1.24–2.32), were community level factors for adolescent girls and young women undernutrition.

Conclusion

One quarter of the Ethiopian adolescent girls and young women were undernourished. Therefore, the Ethiopian government should better engage this age group in different aspects of the food system. To improve nutritional status, public health interventions such as increased media exposure for rural residents and interventions that improve access to protected water sources will be critical.

Effects of Family Demographics and Household Economics on Sidama Children's Nutritional Status

Weight- (WAZ), height- (HAZ), and BMI-for-age (BMIZ) are frequently used to assess malnutrition among children. These measures represent different categories of risk and are usually hypothesized to be affected by distinct factors, despite their inherent relatedness. Life history theory suggests weight should be sacrificed before height, indicating a demonstrable relationship among them. Here we evaluate impact of family composition and household economics on these measures of nutritional status and explore the role of WAZ as a factor in HAZ. Anthropometrics, family demographics, and measures of household economy were collected from Sidama agropastoralist children in a peri-urban village in southwestern Ethiopia (n = 157; 79 girls). Just over half of the sample (50.9%) had z-scores of - 2SD or below on at least one measure, indicating an elevated risk of morbidity/mortality; 30% were at or below - 2SD on two or more measures. We used hierarchical linear regression with random intercept analysis to model WAZ and HAZ. Siblings and crop sales significantly decrease WAZ while electricity, agriculture, and polygyny improve z-scores; however, an interaction between polygyny and siblings indicates negative effects of siblings in polygynous families and positive effects in nonpolygynous ones (adj. R² = 66.5%). For HAZ, agriculture and electricity are positively associated with z-scores whereas siblings have a negative effect; the interaction term again indicates that effects of siblings vary in polygynous and nonpolygynous families (adj. R² = 74.2%). A mediation model exploring the role of weight in height outcomes suggests not only that WAZ has direct effects on HAZ but also that effects of electricity and agriculture on HAZ are partially mediated by WAZ. Our findings indicate that WAZ and HAZ are primarily affected by shared variables, but effects of siblings vary by polygyny status. Long-term outcomes (HAZ) among Sidama children would likely benefit from interventions focused on stabilizing WAZ across family members.

The changes of IgE levels in type 2 inflammatory diseases after treatment of dupilumab: a systematic review and meta-analysis

BACKGROUND

Dupilumab is approved for multiple type 2 inflammatory diseases. In the treatment procedure, the changes of IgE levels need further analysis. We evaluated the changes of IgE levels through a meta-analysis, aiming to provide a more comprehensive result.

RESEARCH DESIGN AND METHODS

Databases were searched to select eligible publications. After being included, study quality was assessed. The standardized mean difference (SMD) was used as an evaluation.

RESULTS

Seven studies were included. At week 4, the level of IgE did not decrease significantly, with SMD=-0.12 (95%CI: -0.31, 0.07) (P>0.05). At week 8, 12, 16, 24 and 52, the level of IgE decreased significantly, which was SMD=-0.26 (95%CI: -0.48, -0.03); -0.25 (95%CI: -0.32, -0.18); -0.49 (95%CI: -0.65, -0.33); -0.30 (95%CI: -0.38, -0.22); -0.40 (95%CI: -0.48, -0.32) (P<0.05). In AD studies, with the increase of IgE levels, due to the decrease in the total dose of dupilumab, the efficacy index showed a decreasing trend.

CONCLUSIONS

Levels of IgE can be significantly decreased in patients with dupilumab treatment. In AD patients, the efficacy was related to total dose; for patients with high IgE levels, efficacy may be better with the dose increased.

Under-Nutrition and Associated Factors Among Lactating Mothers in Ethiopia: A Systematic Review and Meta-analysis

INTRODUCTION

Under-nutrition (body mass index < 18.5 kg/m²) is a global problem with an increasing trend in recent years. The burden is high in low and middle-income countries, especially in Africa. Lactating mothers are among the most vulnerable groups for under nutrition; particularly in sub-Saharan Africa. In Ethiopia, the prevalence of under-nutrition among this group is inconsistent and inconclusive. Therefore, we aimed to assess the pooled prevalence of under-nutrition and its associated factors among lactating mothers in Ethiopia.

METHODS

To write this review and meta-analysis, we followed the preferred reporting items for systematic review and meta-analysis guidelines. Primary articles were searched from PubMed, Hinari, Cochrane Library, science direct databases, Google, and Google scholar. STATA version 16 software and a standardized Microsoft excel format were used for analysis and data extraction, respectively. Heterogeneity between studies was checked. To determine the pooled prevalence of under-nutrition, we used a random-effect model. Begg's and Egger's tests were done to detect publication bias. Subgroup analysis was also steered and association was uttered by a pooled odds ratio with 95% CI.

RESULTS

The pooled prevalence of under-nutrition among lactating mothers was 23.84% [95% CI (19.40, 28.27)]. Educational status (no formal education) {Pooled OR 2.30 [95% CI (1.34, 3.96)]} was significantly associated with under-nutrition.

CONCLUSION

The pooled prevalence of under-nutrition was high. Maternal educational status was significantly associated with under-nutrition. Therefore, the federal ministry of health and the concerned stakeholders should give attention to these most vulnerable groups and strengthen the implementation of the previously designed strategies.

Trends and factors associated with thinness among late adolescent girls in Ethiopia: Multivariate decomposition and multilevel analysis

Background

Undernutrition among adolescent girls is still a major public health problem in low- and middle-income countries (LMICs). Even though the global prevalence of thinness among adolescent girls declined over time, it remains steady in LMICs including Ethiopia. Therefore, this study aimed to assess the trends and factors associated with thinness.

Methods

A logit-based multivariate decomposition analysis for a non-linear response model was fitted to identify factors that contributed to the change in thinness over time. For the associated factors, a multilevel binary logistic regression model was employed. The intra-class correlation coefficient (ICC) and likelihood ratio (LR) test were used to assess the presence of the clustering effect, and deviance was used for model comparison. Statistical significance was declared at p < 0.05.

Results

Thinness among late adolescent girls declined significantly from 34.4% (95% CI: 32.8%, 36.0%) in 2000 to 24.9% (95% CI: 23.4%, 26.5%) in 2016 with an annual average reduction rate of 1.73%. About 84% of the decrement in thinness was attributed to the change in the effect of the characteristics. The place of residence and marital status were significantly associated with a change in thinness due to the change in coefficients. The compositional changes in the age of the adolescents, religion, and types of toilet facilities were also significantly associated with the change in thinness. From the multilevel binary logistic regression, higher age of adolescents (AOR = 0.83; 95% CI: 0.77, 0.90), improved toilet facility (AOR = 0.45; 95% CI: 0.31, 0.65), middle wealth index (AOR = 1.45; 95% CI: 1.10, 1.90), and female head of the household (AOR = 0.77; 95% CI: 0.61, 0.98) were significantly associated at an individual level, whereas being from Somali (AOR = 2.14; 95% CI:1.76, 3.10) and SNNP region (AOR = 0.35; 95% CI: 0.18, 0.68), they had a statistically significant association with thinness at community level.

Conclusion

Thinness among late adolescent girls declined substantially, but it remains a major public health concern. Nutritional interventions targeting thinness reduction among late adolescent girls should base on the identified factors. Age, residence, marital status, type of toilet facility, religion, wealth index, sex of head of the household, and region were all associated with thinness in this study.

Magnitude and Determinants of Under-Nutrition Among Late Adolescent Girls in East Africa: Evidence From Demographic and Health Surveys (2010-2016)

Background

Adolescent girls are vulnerable to undernutrition owing to their increased nutrition demand for growth and development, including sexual development and maturation. Despite its public health importance, undernutrition among late adolescent girls has received little attention in health and nutrition policies. Although undernutrition in adolescent girls has been investigated, most of the previous study reports were based on small sample sizes and limited geographic settings. Therefore, we aimed to estimate the prevalence and determinants of undernutrition among late adolescent girls in East Africa.

Methods

Secondary data analysis was conducted among 10 East African countries using the most recent Demographic and Health Survey (DHS) reports. A total of 21,779 adolescent girls aged 15-19 years were included in this study. Descriptive statistics were conducted to describe the study population. The binary logistic regression model was fitted to identify the determinants of undernutrition among late adolescent girls. Variables with a p-value of <0.05 in the multivariate analysis were identified as statistically significant determinants of undernutrition.

Results

The overall magnitude of undernutrition among late adolescent girls in East Africa was 16.50% (95% CI: 16.00-17.00), whereas the overall magnitude of obesity among late adolescent girls in East Africa was 2.41% (95% CI: 2.21-2.62). In the final model of the multivariate analysis, adolescent girls aged 18-19 years [adjusted odds ratio (AOR) = 0.55; 95% CI: 0.51-0.60], having secondary education (AOR = 0.79; 95% CI: 0.68-0.93), being from a rich wealth index family (AOR = 0.63; 95% CI: 0.56-0.69), and being from a medium wealth index family (AOR = 0.80; 95% CI: 0.72-0.89) were negatively and statistically associated with undernutrition. Likewise, having more than seven household members (AOR = 1.36; 95% CI: 1.10-1.67), walking more than 30 min to a water source (AOR = 1.10; 95% CI: 1.01-1.20), and living in Ethiopia (AOR = 1.75; 95% CI: 1.51-2.03) were positive determinants of undernutrition among late adolescent girls.

Conclusion

In this study, undernutrition in late adolescent girls remains a considerable public health problem in East Africa. Age group, educational status, marital status, family wealth index, family size, time taken to reach a water source, media exposure, and country of resident were significant determinants of undernutrition. Therefore, devising strategies that improve the socioeconomic status of households and/or adolescents would help to reduce the risks of undernutrition in late adolescents.

Use of modified composite index of anthropometric failure and MUAC-for-age to assess prevalence of malnutrition among school-age children and adolescents involved in the school feeding program in Addis Ababa, Ethiopia

Background

Malnutrition hampers educational performance of schoolchildren coming from low-income families. School feeding program was, thus, launched in public primary schools in Addis Ababa very recently. It is, thus, important to measure the initial nutritional status of participating students to see the effect of the program on their nutritional wellbeing.

Methods

The first-round survey was made at the initiation of the program. A multi-stage stratified sampling from 50 schools located in the ten sub cities of Addis Ababa yielded 4500 children and adolescents of ages five to 19 years. Data was collected on age, height, weight and MUAC of the schoolchildren. Nutritional status was evaluated using conventional anthropometric indicators, modified Composite Index of Anthropometric Failure (mCIAF), and MUAC-for-age. Receiver Operating Characteristic (ROC) curve was used to examine classification of malnourishment by MUAC-for-age versus BMI-for-age and mCIAF versus MUAC-for-age. Multilevel mixed effects model was applied to investigate variations in the prevalence of malnutrition across sub cities.

Findings

The area under the ROC curves (AUC) for MUAC-for-age against BMI-for-age z-scores was 0.68 and that of mCIAF against MUAC-for-age was 0.70, respectively, indicating an overall better classification of malnourishment. Mixed effects model showed significant variations in nutritional status of schoolchildren across sub cities. Conventional measures showed that prevalence of stunting, thinness, or underweight among the sample children and adolescents was 23.4, 18.4, and 16.5%, respectively. Assessment by mCIAF, instead, showed a higher prevalence of overall malnutrition (43.4%). MUAC-for-age indicated an acute malnutrition measurement of 33.4%. Significant differences (p < 0.0001) in nutritional status were seen between boys and girls, and among age groups as measured by mCIAF.

Interpretation

Conventional measures of nutritional status undermined level of malnutrition. Instead, mCIAF and MUAC-for-age gave higher estimates of the magnitude of the existing prevalence of malnutrition among the school children and adolescents.

Inadequacy of nutrient intake among adolescent girls in south central Ethiopia

Adolescent undernutrition is a major public health problem in Ethiopia. Inadequate dietary intake of nutrients is the major determinants of undernutrition. However, the adequacy of dietary intake among adolescents was not sufficiently explored. The present study aims to estimate the inadequacy of nutrient intake among adolescent girls in south central Ethiopia. A community-based cross-sectional study was conducted. We assess food and nutrient intake using repeated multiple-pass 24-h dietary recall. The study was conducted in Damot Gale district, Woliyta zone, Southern Ethiopia. Data were collected from 288 female adolescents. The majority of adolescent girls consumed cereals (96⋅9 %) and roots/tubers (75⋅3 %). However, only less than 1 % of them consumed flesh food. The mean energy, carbohydrate, protein and dietary fibre intake of the adolescent girls per day was 1452⋅7 ± 356⋅3 kcal, 305⋅6 ± 72⋅4 g, 35⋅7 ± 13⋅3 g and 18⋅6 ± 8⋅4 g, respectively. The median fat intake was 13⋅3 g (IQR 8⋅8, 19⋅8). The contribution of carbohydrate, protein and fat for the total energy was 80, 10 and 8 %, respectively. The prevalence of inadequate intake of protein was 60⋅9 %. The prevalence of inadequate intake of iron for early adolescents and late adolescents was 82 and 53 %, respectively. The prevalence of inadequate intake of folate was 83⋅9 % and zinc was 58 %. The prevalence of inadequate intake was greater than 90 % for vitamin B12, vitamin C and calcium. The present study found an alarmingly high prevalence of inadequate intake of some nutrients among adolescent girls of Damot Gale district.

Spatial patterns and determinants of undernutrition among late-adolescent girls in Ethiopia by using Ethiopian demographic and health surveys, 2000, 2005, 2011 and 2016: a spatial and multilevel analysis

Background

Undernutrition among late-adolescent girls (15–19 years) in Ethiopia is the highest among Southern and Eastern African countries. However, the spatial variation of undernutrition as a national context is not well understood in Ethiopia. This study aimed at the spatial patterns and determinants of undernutrition among late-adolescent girls in Ethiopia.

Methods

Secondary data analysis was conducted from women’s data of four consecutive Ethiopian Demographic and Health Surveys (EDHS) from 2000 to 2016. A total of 12,056 late-adolescent girls were included in this study. The global spatial autocorrelation was assessed using the Global Moran’s I autocorrelation to evaluate the presence of geographical clustering and variability of undernutrition. SaTScan cluster analysis by using the Bernoulli model to detect most likely SaTScan cluster areas of significant high-rate and low-rate of undernutrition was explored. A Multilevel binary logistic regression model with cluster-level random effects was fitted to determine factors associated with undernutrition among late-adolescent girls in Ethiopia.

Results

Undernutrition was clustered nationally during each survey (Global Moran’s I = 0.009–0.045, Z-score = 5.55–27.24, p-value < 0.001). In the final model, individual and community level factors accounted for about 31.02% of the regional variations for undernutrition. The odds of undernutrition among 18–19 years of adolescent girls, was 57% (AOR = 0.43; 95% CI: (0.35–0.53) lower than those 15–17 years old. Late-adolescent girls with higher educational status were 4.40 times (AOR = 4.40; 95% CI: (1.64–11.76) more likely to be undernourished than those with no educational status. The odds of undernutrition among late-adolescent girls, with the occupation of sales, was 40% (AOR = 0.60; 95% CI: 0.43–0.84) lower than those with not working adolescents. The odds of undernutrition, among late-adolescent girls, having an unimproved latrine type, was 1.79 times (AOR = 1.79; 95% CI: 1.15–2.79) higher than those participants with improved latrine type. The odds of undernutrition among late-adolescent girls with rural residents was 2.33 times higher (AOR = 2.33; 95% CI: 1.29–4.22) than those with urban residents.

Conclusion

Undernutrition among late-adolescent girls was spatially clustered in Ethiopia. The local significant clusters with high prevalence of undernutrition was observed in Northern and Eastern Ethiopia. Those regions with a high prevalence of undernutrition should design interventions to combat undernutrition.

Intestinal Parasite Infection and Its Association with Undernutrition among Early Adolescents in Hawassa University Technology Village, Southern Ethiopia

Background. Different studies presented negating findings of the association between intestinal parasite infections (IPIs) and undernutrition among early adolescents in Ethiopia. This study was aimed at assessing intestinal parasite infection and its association with undernutrition among early adolescents in four selected districts of the Sidama region. Method. An institution-based cross-sectional study was conducted in October 2020 among 792 early adolescents. The multistage stage sampling was applied to select 16 primary schools. Simple random sampling was applied to select study participants. Trained data collectors administered questionnaires. Stool samples were collected and analyzed. Anthropometric measurements were taken and indices were calculated using AnthroPlus software. Data were entered into and analyzed by SPSS version 25 software. Association between IPI and undernutrition was measured using multivariable analysis. The outputs are presented using an adjusted odds ratio (AOR) with 95% confidence intervals (CIs). Result. The prevalence of IPI, thinness, and stunting was 32% (95% CI: 28.7%, 35.3%), 17.5% (95% CI: 14.8%, 20.2%), and 21.5% (95 CI: 18.6%, 24.4%), respectively. The higher odds of IPIs were observed among adolescents stunted (AOR = 3.61; 95% CI: 2.44–5.33), those who are thin (AOR = 3.07; 95% CI: 2.02–4.66), those who did not wash their hands after toilet (AOR = 1.89; 95% CI: 1.35–2.66), those who ate raw meat (AOR = 1.50; 95% CI: 1.03–2.14), and those whose family did not own toilet (AOR = 1.71; 95% CI: 1.18–2.46). Conclusion. The prevalence of IPI, thinness, and stunting was high and has public health significance in the study area. IPIs were associated with stunting, thinness, lack of toilets, not washing hands after a toilet visit, and eating raw meat. Strengthening nutrition interventions, deworming programs, and health education on personal and environmental hygiene and sanitation are recommended.

Growth dynamics among adolescent girls in Bangladesh: Evidence from nationally representative data spanning 2011-2014

Background

Adolescence is the last opportunity to reverse any growth faltering accumulated from fetal life through childhood and it is considered a crucial period to optimize human development. In Bangladesh, a growing double burden of underweight and obesity in adolescents is recognized, yet limited data exists on how, when, and where to intervene. This study assesses the dynamics of growth among adolescent girls in Bangladesh, providing insight about critical junctures where faltering occurs and where immediate interventions are warranted.

Methods

We pooled data from Bangladesh’s Food Security and Nutrition Surveillance Project collected between 2011 and 2014 to document the age dynamics of weight and linear growth. 20,572 adolescent girls were measured for height and 19,345 for weight. We constructed growth curves for height, weight, stunting, and underweight. We also stratified growth dynamics by wealth quintile to assess socioeconomic inequities in adolescent trajectories.

Results

Height-for-age z-score (HAZ) in Bangladeshi girls deteriorates throughout adolescence and especially during the early years. Mean HAZ decreases by 0.20 standard deviations (sd) per year in early adolescence (10–14 years) vs 0.06 sd/year during late adolescence (15–19 years), while stunting increases by 16 percentage points (pp) vs 6.7 pp, respectively. Conversely, BMI-for-age z-score (BAZ) increases by 0.13 sd/year in early adolescence vs 0.02 sd/year in late adolescence, and underweight decreases by 12.8 pp vs 3.2 pp. Adolescent girls in all socioeconomic groups show a similar pattern of HAZ and BAZ dynamics, but the curve for the richest quintile stays above that of the poorest across all ages.

Conclusions

Trends and levels of stunting and underweight among adolescent girls in Bangladesh are worrisome, suggesting substantial linear growth faltering in early adolescence, with improving weight-for-age occurring only as linear growth slows and stops. Given the rising burden of non-communicable diseases (NCDs) in Bangladesh and emerging evidence of the link between stunting and later chronic diseases, greater attention to adolescent growth and development is needed. Our findings suggest that, to address stunting, interventions in early adolescence would have the greatest benefits. School-based interventions could be a way to target this population.

Prevalence and Determinants of Stunting and Thinness/Wasting Among Schoolchildren of Ethiopia: A Systematic Review and Meta-Analysis

BACKGROUND

Several studies have been carried out assessing the prevalence of undernutrition and possible determinants among schoolchildren in Ethiopia, but there is a lack of systematically gathered and analyzed information.

OBJECTIVE

This systematic review and meta-analysis aimed to summarize epidemiological data on undernutrition and possible determinants among schoolchildren in Ethiopia.

METHODS

We conducted a systematic review using open access articles that report the prevalence of stunting and wasting/thinness among schoolchildren from PubMed Central, Scopus, and Science direct. The pooled prevalence was determined using a random-effect model while heterogeneities between studies were evaluated by I ² test.

RESULTS

A total of 24 716 schoolchildren were included in the 39 eligible articles. The prevalence of stunting and wasting/thinness among schoolchildren in Ethiopia were 23.1% (95% CI: 19.0-27.0) and 22% (95% CI: 17-26), respectively. There was a marked difference in the prevalence of stunting and wasting/thinness across regions of Ethiopia. The risk of stunting was increased with meal frequency ≤3 times a day (odds ratio [OR] = 3.02, 95% CI: 1.90-4.14), age >10 years (OR = 2.16, 95% CI: 1.47-2.85), and family size ≥5 (OR = 1.88, 95% CI: 1.40-2.35). Similarly, the risk of wasting/thinness was increased with male sex (OR = 2.06, 95% CI: 1.54-2.58), low family income (OR = 2.16, 95% CI: 1.30-3.01), and age >10 years (OR = 1.78, 95% CI: 0.74-2.82).

CONCLUSION

This study revealed that more than one-fifth of schoolchildren are stunted or wasted/thin in Ethiopia. Large family size, male sex, and student age were consistently associated with stunting and wasting/thinness among schoolchildren. This study highlights the importance of an integrated effort to reduce undernutrition in Ethiopia.

Mid-upper arm circumference as a screening tool for identifying adolescents with thinness

OBJECTIVE

To evaluate the performance of mid-upper arm circumference (MUAC) to identify thinness in the late adolescence period (aged 15-19 years) in Ethiopia.

DESIGN

We conducted a school-based cross-sectional study. The receiver operating characteristics curve was used to examine the validity of MUAC compared with BMI Z-score to identify adolescents with thinness (BMI Z-score <-2 sd).

SETTINGS

Fifteen high schools (grade 9-12) located in Addis Ababa, Ethiopia.

PARTICIPANTS

A total of 851 adolescent (456 males and 395 females) were included in the study.

RESULTS

The prevalence of thinness and severe thinness among high-school adolescents in Addis Ababa was 9·5 % (95 % CI 7·7, 11·7 %). The overall AUC for MUAC against BMI Z-score <-2 SD was 0·91 (95 % CI 0·88, 0·93). The optimal MUAC cut-offs to identify thinness were 23·3 cm for males and 22·6 cm for females. These cut-off points give high sensitivity and specificity for both males (a sensitivity of 87·9 % and a specificity of 75·9 %) and females (a sensitivity of 100 % and a specificity 88·2 %).

CONCLUSIONS

MUAC has a comparable level of accuracy with BMI Z-score to identify thinness in adolescents aged 15-19 years. Hence, MUAC could be used as an alternative tool for surveillance and screening of thinness among adolescents aged 15-19 years. The optimum cut-off proposed by this study may incorrectly include a large number of adolescents when used in a relatively well-nourished population. In this situation, it would be necessary to choose a cut-off with greater positive predictive value.

Undernutrition Among HIV-Positive Adolescents on Antiretroviral Therapy in Southern Ethiopia

Purpose

Adolescents living with HIV are vulnerable to undernutrition secondary to elevated nutritional needs imposed by growth spurt and HIV-infection. Yet, in low-income countries, evidence on the epidemiology of undernutrition among adolescents living with HIV is scarce. We assessed the prevalence and predictors of stunting and thinness among adolescents receiving anti-retroviral therapy (ART) in Hawassa city, Southern Ethiopia.

Methods

In this facility-based cross-sectional study, we enrolled 260 adolescents (10–19 years of age) living with HIV on ART in two public hospitals and three health centers. Anthropometric measurements, household food insecurity and dietary diversity were measured following standard approaches. Predictors of stunting and thinness were identified using multivariable logistic regression analyses and interpreted using adjusted odds ratio (AOR) with 95% confidence interval (CI).

Results

One-third of the adolescents were stunted, and 20% were thin. The prevalence of severe stunting (7.7%) and severe thinness (7.3%) was also high. Significant proportions of the adolescents (38.5%) were from food insecure households, and 28.1% had low or medium dietary diversity. Significant predictors of stunting were lack of food or financial support (AOR=2.71; 95% CI: 1.36–5.39); meal skipping (AOR=2.13; 95% CI: 1.16–3.91); recent history of opportunistic infections (AOR=2.25; 95% CI: 1.11–4.55) and disclosure of HIV status to the adolescent (AOR=1.88; 95% CI: 1.12–4.34). History of opportunistic infection was the only significant predictor of thinness (AOR=3.21; 95% CI: 1.54–6.73).

Conclusion

The burden of undernutrition among adolescents living with HIV is disturbingly high. Prevention of opportunistic infections promoting social support and discouraging practice of meal skipping may help to reduce the problem.

Defining diet quality: a synthesis of dietary quality metrics and their validity for the double burden of malnutrition

Achieving most of the UN Sustainable Development Goals requires a strong focus on addressing the double burden of malnutrition, which includes both diet-related maternal and child health (MCH) and non-communicable diseases (NCDs). Although, the most optimal dietary metric for assessing malnutrition remains unclear. Our aim was to review available global dietary quality metrics (hereafter referred to as dietary metrics) and evidence for their validity to assess MCH and NCD outcomes, both separately and together. A systematic search of PubMed was done to identify meta-analyses or narrative reviews evaluating validity of diet metrics in relation to nutrient adequacy or health outcomes. We identified seven dietary metrics aiming to address MCH and 12 for NCDs, no dietary metrics addressed both together. Four NCD dietary metrics (Mediterranean Diet Score, Alternative Healthy Eating Index, Healthy Eating Index, and Dietary Approaches to Stop Hypertension) had convincing evidence of protective associations with specific NCD outcomes, mainly mortality, cardiovascular disease, type 2 diabetes, and total cancer. The remaining NCD dietary metrics and all MCH dietary metrics were not convincingly validated against MCH or NCD health outcomes. None of the dietary metrics had been validated against both MCH and NCD outcomes. These findings highlight major gaps in assessing and addressing diet to achieve global targets and effective policy action.
