Improving dietary diversity of school adolescents through school based nutrition education and home gardening in Jimma Zone: Quasi-experimental design

Associated factors of dietary diversity among schoolchildren in Plateau Central region of Burkina Faso: a cross-sectional study

CONTEXT

School-age is a dynamic period of growth and development, leading to good health and a productive adult life. Adequate dietary intake provides essential nutrients for growth, health and cognition. However, the practices of adequate nutrition is still not a matter of course for schoolchildren in many countries. The aim of this study was to identify associated factors of dietary diversity among students in public primary school in the Central Plateau Region.

METHOD

Multi-stage sampling was used to select schoolchildren. A semi-structured questionnaire was used to collect information's of food consumption at home and at school using a 24-h dietary recall method. Binary logistic regression was used to identify variables associated with students' dietary diversity scores (DDS) with statistical significance at p < 0.05, after performing Chi-square test of independence to identify candidates variables at p < 0.25.

RESULTS

The study involved 560 pupils aged 6 to 14 older, including 52.9% girls and 47.9% boys. Dietary diversity was divided into three classes: low (DDS ≤ 4), medium (DDS = 5) and high (DDS ≥ 6). Thus, 13.4% of students have a low DDS and average in 48.9%, versus 37.7% high. Students in Ganzourgou were twice as likely to have a low DDS (AOR = 2.01, 95% CI:1.00-4.04) compared to those in Oubritenga. Household drinking water source, pupil status and father's occupation were significantly associated with pupils' dietary intake.

CONCLUSION

Primary schoolchildren don't have good dietary practices in the Plateau Central Region. Promoting dietary diversification in households and balanced meals in school canteens would be necessary to improve the DDS of schoolchildren.

Assessment of nutrition knowledge and associated factors among secondary school students in Haramaya district, Oromia region, eastern Ethiopia: implications for health education

Background

Nutrition knowledge stands as a cornerstone in facilitating informed dietary choices, thereby profoundly impacting overall health and lifestyle outcomes. Malnutrition often correlates with deficient nutritional knowledge, highlighting the critical need for comprehensive understanding in this domain. While Ethiopia has seen considerable research on nutritional status and associated factors, there remains a paucity of studies specifically addressing nutrition knowledge among secondary school students, particularly within the Haramaya District. Therefore, this study aimed to meticulously assess nutrition knowledge and its determinants among secondary school students in Eastern Ethiopia.

Methods

Employing an institutional-based cross-sectional design, we carefully selected 417 students from secondary schools in Haramaya District, Eastern Ethiopia, through simple random sampling. Data Research Topic entailed structured interviews, with subsequent entry into Epi Data version 3.1 for meticulous analysis utilizing SPSS version 21 software. Descriptive statistics summarized participant characteristics, while both bivariable and multivariable logistic regression analyses were conducted to elucidate factors associated with nutritional knowledge, setting statistical significance at p-value <0.05.

Results

All 417 selected students participated in the study, yielding a commendable response rate of 100%. The median nutritional knowledge score among students stood at 58, with an interquartile range spanning from 44 to 66. Approximately 46.76% (95% CI: 42-51.59) of students exhibited good nutritional knowledge. Significant determinants of nutrition knowledge included sex [adjusted odds ratio (AOR) = 1.77, 95% CI: 1.03-3.04], being senior secondary students (AOR = 3.3, 95% CI: 1.95-5.73), and access to nutrition information (AOR = 3.3, 95% CI: 1.60-6.87).

Conclusion

Our findings illuminate a notable level of nutritional knowledge among secondary school students in Haramaya District. However, discernible disparities in nutrition knowledge emerged based on gender, educational level, and access to nutrition information. These insights underscore the exigency of targeted interventions aimed at enhancing nutrition literacy among students, thereby fostering holistic health promotion endeavors.

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.

Dietary diversity and associated factors among adolescent girls in Nifas Silk Laphto sub city, Addis Ababa, Ethiopia, 2021

BACKGROUND

Addressing the nutritional problems of adolescent girls is important as their nutritional status has a negative effect on the future generation. However, the evidence revealed the variation and unrelated data on the prevalence of dietary diversity and lack of including all adolescent age and community groups in Ethiopia. Hence, this study assessed dietary diversity and associated factors among adolescent girls in Nifas Silk Laphto Sub-city, Addis Ababa Ethiopia, 2021.

METHODS

A community-based cross-sectional study was conducted among 475 adolescent girls at Nifas Silk Laphto sub-city, Addis Ababa Ethiopia from July 1 to 30, 2021. Multistage cluster sampling was employed to select adolescent girls. Pretested questionnaires were used to collect the data. The data were checked for completeness and entered by Epidata version 3.1 and cleaned and analyzed by SPSS version 21.0. A multivariable binary logistic regression model was fitted to identify factors associated with dietary diversity scores. The degree of association was assessed using an odds ratio with a 95% confidence interval and variables with p-value ≤ 0.05 were considered significant.

RESULT

The mean and the standard deviation of dietary diversity scores were 4.70 and 1.21 respectively. The proportion of low dietary diversity scores among adolescent girls was 77.2%. Adolescent girls' age, meal frequency, wealth index of household, and food insecurity were significant determinants of dietary diversity score.

CONCLUSION

The magnitude of low dietary diversity scores was significantly higher in the study area. Adolescent girls', meal frequency, wealth index, and food security status were predictors of dietary diversity score. School-based nutrition education and counseling and designing strategies for improving household food security programs are crucial.

Dietary diversity modification through school-based nutrition education among Bangladeshi adolescent girls: A cluster randomized controlled trial

OBJECTIVE

To measure the efficacy of school-based nutrition education on dietary diversity of the adolescent girls in Bangladesh.

METHODS

A matched, pair-cluster randomized controlled trial was conducted from July 2019 to September 2020. Randomization was done to select intervention and control schools. There were 300 participants (150 in the intervention and 150 in the control arm) at baseline. We randomly selected our study participants (adolescent girls) from grades six, seven, and eight of each school. Our intervention components included parents' meetings, eight nutrition education sessions, and the distribution of information, education, and communication materials. An hour-long nutrition education session was provided using audio-visual techniques in a class of intervention school once a week by trained staffs of icddr,b for two months. Data on dietary diversity, anthropometry, socio-economic and morbidity status, a complete menstrual history, and haemoglobin status of adolescent girls were collected at recruitment and after five months of intervention. We calculated the mean dietary diversity score of adolescent girls at baseline and at the endline. As the dietary diversity score was incomparable between the control and intervention arm at baseline, we performed the difference-in-difference analysis to assess the effect of the intervention.

RESULTS

Mean age of the adolescent girls was 12.31 years and 12.49 years in the control and intervention arms respectively. Percentages of consumption of organ meat, vitamin A-rich fruits and vegetables, legumes, nuts, and seeds were higher in the intervention arm than in the control arm at the end-line. The mean dietary diversity score remained unchanged in the control arm at 5.55 (95% CI: 5.34-5.76) at baseline and 5.32 (95% CI: 5.11-5.54) at the endline. After the intervention, mean dietary diversity increased from 4.89 (95% CI: 4.67-5.10) at baseline to this mean was 5.66 (95% CI: 5.43-5.88) at the endline. Result from the difference-in-difference analysis revealed that the mean dietary diversity was likely to increase by 1 unit due to intervention.

CONCLUSION

The shorter duration of the intervention in our study could not show whether it could change the behavior of adolescent girls in increasing dietary diversity through school-based nutrition education, but it showed a pathway for increasing dietary diversity at school. We recommend including more clusters and other food environment elements in retesting to increase precision and acceptability.

Educational intervention and livestock ownership successfully improved the intake of animal source foods in 6-23 months old children in rural communities of Northern Ethiopia: Quasi-experimental study

Background

Animal source foods (ASFs) are rich in high-quality proteins, including essential amino acids and highly bioavailable micronutrients vital for child growth and cognitive development. But, the daily consumption of ASFs among 6–23 months old children is very low in Tigray, Northern Ethiopia.

Objective

The study aimed to assess the effectiveness of nutrition education intervention to improve the consumption of ASFs among 6–23 months old children from rural communities with strict religious fasting traditions of avoiding intake of ASFs in Northern Ethiopia.

Methods

A quasi-experimental study was conducted in two food insecure districts namely Samre Seharti (intervention) and Tanqua Abergele (comparison). The mother-child pairs in the intervention group (n = 140) received nutrition education based on the barriers and available resources for optimal consumption of ASFs among children and followed up for nine months. The mother-child pairs in the comparison group (n = 153) received routine nutrition education. The data were collected using a pre-tested structured questionnaire. The baseline and endline data assessment included interviews on socio-demographic and socio-economic status, dietary intake, and child feeding practices. The effectiveness of the intervention was measured using the difference-in-difference (DID) analysis model.

Results

At endline, the consumption of ASFs among children was 19.5 percentage points higher in the intervention group compared with the comparison group (p = 0.008). In addition, there was a significant increase in egg consumption among children in the intervention group (DID of 16.9, p = 0.012) from the comparison group. No child was consuming meat at baseline in both the intervention and comparison arms and it was very low at endline (5.2% vs. 7.9%). Overall, the proportion of children that consumed eggs in the intervention group was higher than in the comparison group in households that owned sheep and goats (4.8% vs. 21.4%, p = 0.050) and chicken (6.3% vs. 43.8%, p = 0.002) after education interventions. However, no statistically significant difference was observed between cow ownership and milk consumption among children (p>0.05).

Conclusions

Age-appropriate educational interventions for mothers and owning small livestock in the household can improve the consumption of ASFs and eventually the minimum diet diversity of children in communities with strict religious traditions of avoiding ASFs during the fasting seasons.

The Socio-Cultural Benefits of Urban Agriculture: A Review of the Literature

Despite extensive literature on the socio-cultural services of urban open spaces, the role of food-producing spaces has not received sufficient attention. This hampers advocacy for preserving and growing urban agricultural activities, often dismissed on justifications that their contributions to overall food supply are negligible. To understand how the social benefits of urban agriculture have been measured, we conducted a systematic review of 272 peer-reviewed publications, which drew on insights from urban agriculture sites in 57 different countries. Through content analysis, we investigated socio-cultural benefits in four spheres: engaged and cohesive communities, health and well-being, economic opportunities, and education. The analysis revealed growth in research on the social impacts of gardens and farms, with most studies measuring the effects on community cohesion and engagement, followed by increased availability and consumption of fruits and vegetables associated with reduced food insecurity and better health. Fewer studies assessed the impact of urban farming on educational and economic outcomes. Quantifying the multiple ways in which urban agriculture provides benefits to people will empower planners and the private sector to justify future investments. These findings are also informative for research theorizing cities as socio-ecological systems and broader efforts to measure the benefits of urban agriculture, in its many forms.

The influence of fasting on energy and nutrient intake and their corresponding food sources among 6-23 months old children in rural communities with high burden of stunting from Northern Ethiopia

BACKGROUND

Limited studies in Ethiopia showed that infants and young children are at high risk of inadequate intake of energy and nutrients. However, inclusive assessment of both nutrient intakes and their food sources are lacking. We aimed at assessing energy and nutrient intakes and their food sources during religious fasting and non-fasting periods among 6-23 months old children in Northern Ethiopia.

METHODS

Data for this longitudinal study were collected following repeated multiple-pass 24-h dietary recall technique through face-to-face interviews with primary caregivers. Using a two-stage systematic random sampling method, a total of 570 and 551 children participated respectively in the lent fasting and non-fasting periods. Energy and nutrient intakes were estimated and compared with WHO daily requirements. All foods that a child consumed on the day preceding the date of data collection were recorded and processed with database software. Chi-square and t- tests were used to analyze the data. Non-normally distributed data were analyzed using Wilcoxon signed-rank test and statistical significance was set at p < 0.05.

RESULTS

The overall prevalence of child stunting was 41.4%. Almost all of children (99.6%) consumed grains, roots, and tubers. The inadequacy prevalence of energy, protein and eight selected micronutrients (calcium, iron, zinc, vitamin A, thiamin, riboflavin, niacin, vitamin C) intake were 96.2, 44.9, and 95.5%, respectively. Calcium and zinc were the highest (100%) deficits observed across all age groups. Although consumption of animal source foods (ASFs) was very low (dairy 10.1%, meat 2.3% and eggs 23.6%), there was significantly higher consumption of meat and eggs during the non-fasting compared to fasting period (p < 0.001).

CONCLUSIONS

Inadequate intake of energy and nutrients was common among 6-23 months old children. Cereals were found to be the main sources of many of the nutrients. The consumption of ASFs among 6-23-month-old children was low which was also affected by the religious fasting period. Hence, strengthening social and behavior change communication, supporting rural households to raise poultry and small ruminants is recommended.

Prevalence of excess body weight and associated factors among secondary school adolescent girls in northern Tanzania: a cross-sectional study

Introduction

excess body weight among adolescents is on the increase and has become a global public health challenge. It is likely to persist to adulthood, exposing to risk of developing chronic diseases. However, there is insufficient information on the prevalence of excess body weight and associated factors among adolescent girls in secondary schools in northern Tanzania.

Methods

this cross-sectional study involved 400 secondary school adolescent girls, selected by multi-stage cluster sampling. A self-administered questionnaire was used to gather information. Anthropometric measurements were taken and body mass index calculated. Descriptive statistics summarized the data. Logistic regression was used to model excess body weight resulting into adjusted odds ratios with their 95% confidence intervals and significant level was set at p-value<0.05.

Results

the proportion of adolescents with excess body weight (BMI >+1SD) was 23%. The majority (63%), reported unhealthy dietary habits while half (51.5%) of them had moderate level of knowledge on healthy eating. Compared to working as a civil servant, the odds of having excess body weight among girls whose mothers/female guardians were housewives was less by 60% (aOR=0.4, 95%CI: 0.2, 0.9). Furthermore, the odds of having excess body weight among adolescents eating unhealthy foods were almost six times higher compared to their peers on healthy diet (aOR=5.8, 95%CI: 2.9, 11.3).

Conclusion

prevalence of excess body weight among adolescent girls in northern Tanzania is high. Unhealthy dietary habits and mother's/female guardian's occupation were significant correlates of excess body weight. We recommend platforms to inform adolescents on the importance of proper food intake and to advance knowledge on dangers of excessive weight gain as a strategy towards prevention of nutrition-related diseases.

Exploration of Barriers to the Uptake of Nutritional Services Among Adolescent Girls from the Rural Communities of Tigray Region, Northern Ethiopia: A Qualitative Study

Background

Adolescence is a time of tremendous physical growth and mental development, with high nutrient requirements. Ethiopia is among the countries with a high prevalence of nutritional deficiencies among the women of reproductive age group, whilst adolescent girls from rural areas suffered disproportionately. However, there is a dearth of evidence regarding the barriers that hinder adolescent girls to utilize the available nutritional services.

Purpose

The current study aimed to qualitatively explore the range of barriers for the uptake of nutritional interventions among adolescent girls in rural communities of Tigray, Northern Ethiopia.

Methods and Participants

We employed an explorative qualitative study among purposively selected adolescent girls and school teachers from rural districts of Tigray region. We conducted 11 focused group discussions with adolescent girls, 17 in-depth interviews (seven with teachers, seven with in-school adolescent girls, and three with out-of-school adolescent girls) using a semi-structured guide. Data was audio-taped, transcribed verbatim in local language, translated into English, and imported into ATLAS.ti version 7.5 qualitative data analysis software for analysis.

Results

Adolescents perceived that stunting, anemia, and thinness are among the main nutritional problems in their community. Food insecurity, limited nutrition awareness in the community, limited access to a water source, high workload, service provider's little attention for adolescents' nutrition, and food taboo have emerged as barriers for the uptake of adolescent girls' nutritional interventions. Though limited in reach, available nutritional interventions include awareness creation, nutritional supplementation, and disease prevention.

Conclusion

Food insecurity poses a strong challenge to adolescent girls' nutrition. As access to safe drinking water continues to be a considerable bottleneck for nutritional interventions, a multi-sectoral response to integrate water, sanitation, and hygiene (WASH) services is required. Bounded by food taboo, high burden of workload among the adolescent girls, women empowerment and nutritional status seem to be the unfinished agenda in resource limited settings such as the rural areas of Tigray region.

Dietary diversity practice and associated factors among adolescent girls in Dembia district, northwest Ethiopia, 2017

Background

Dietary diversity is defined as the number of food groups or items consumed over a reference period, and usually, it is a problem in developing countries including Ethiopia. Inadequate dietary diversity is one of a major public health problem and can result in physical, emotional, and psychological changes among adolescents. However, studies on dietary diversity among school children were very limited. Hence, this study aimed at determining dietary diversity practices and factors among adolescents in Dembia district.

Methods

A school-based cross-sectional study was conducted from March 1 to April 15, 2017, at Dembia district, northwest Ethiopia. A total of 474 study subjects were selected using the multi-stage sampling technique. A structured and pre-tested questionnaire was used to collect the data. Dietary diversity was measured through standard tool adopted from Food and Nutrition Technical Assistance (FANTA) 2016 using the 24-h recall method. A multivariable binary logistic regression model was employed to identify factors associated with a diversified diet.

Result

This study illustrated that 32.3% (95% CI 27.9–36.8) of the adolescents had adequate dietary diversity. Inadequate dietary diversity was significantly associated with being Muslim (AOR = 0.3; 95% CI 0.1–0.7), self-employment (AOR = 0.3; 95% CI 0.1–0.9), middle (AOR = 0.5; 95% CI 0.3–0.8) and high wealth category (AOR = 0.3; 95% CI 0.2–0.6), and underweight (AOR = 3.5; 95% CI 1.3–9.5).

Conclusion

The findings of this study showed that only one-third of adolescent girls have adequate dietary diversity. Low level of dietary diversification suggested points to the need for strengthening efforts targeting to improve the healthy dietary practice of adolescents by giving due attention to poor households and undernourished adolescents.

Assessment of high school learners' familiarity with nutrition education principles

BACKGROUND/OBJECTIVES

The objective of the study was to assess adolescent learners' nutritional knowledge to suggest early intervention strategies that address knowledge deficiency gaps that have a negative impact on personal health and productivity.

SUBJECTS/METHODS

A cross-sectional survey design was used in the study. One circuit was purposively selected from Pinetown District, KZN, South Africa. A representative sample of 108 learners was randomly selected from 7 of the 8 schools in the district to complete the investigator administered questionnaire between July and August 2017.

RESULTS

Although the majority of learners were familiar with the nutrition education principles, a large proportion lacked the knowledge of essential nutrition and were in support of the incorporation of various strategies to promote nutrition education. Friedman test revealed significant differences, χ² (3) = 192.4, p < 0.001, between the mean rank scores of familiarity to different nutrition principles. Relative to other principles, balanced diet and food groups were the most critical issues. The overall mean of 3.7 for learners' priority level on nutrition education principles indicated the learners' view that knowledge of all principles was necessary for the attainment of a healthy lifestyle.

CONCLUSIONS

Many learners were not familiar with nutrition education principles. Hence this paper becomes very critical as it communicates the information to the community and suggests various nutrition education intervention strategies that have to be put in place in the school system to impart the necessary knowledge and skills that promote a long-term healthy lifestyle for the learners.

Exploring Rural Adolescents' Dietary Diversity and Its Socioeconomic Correlates: A Cross-Sectional Study from Matlab, Bangladesh

The majority of 36 million Bangladeshi adolescents live in rural areas. Improved understanding of their dietary patterns is of great public health importance. This study aimed to explore dietary diversity (DD) with its socioeconomic and gender stratification in a rural adolescent cohort and to isolate factors associated with inadequate DD. Household survey provided data for constructing dietary diversity scores (DDS) and assessing relevant socio-demographic variables. Final analysis included 2463 adolescents. Means and proportions were compared, and a binary logistic regression model was fitted. Inadequate DD was observed among 42.3% (40.3–44.2). Consumption of nutrient-rich foods varied significantly across gender and SES categories. Belonging to the poorest households (adjusted odds ratio (aOR) 1.59; 95% CI: 1.27, 2.00) and food insecure households (aOR 1.34; 95% CI: 1.13, 1.59), adolescents’ attainment of secondary education (aOR 1.38; 95% CI: 1.11, 1.71), and having mothers with secondary education or above (aOR 0.76; 95% CI: 0.60, 0.96) were associated with inadequate DD. Compared with girls from food secure households, girls from food insecure ones had higher odds of inadequate DD (aOR_girl 1.42; 95% CI: 1.12, 1.81). Improving rural adolescents’ DD would require targeted interventions as well as broader poverty alleviation.

Dietary Diversity and Its Association with Anemia among Pregnant Women Attending Public Health Facilities in South Ethiopia

Background

Anemia is a major public health problem among pregnant women in developing countries like Ethiopia. Nutritional deficiency related to anemia is an important contributor to maternal mortality and poor fetal outcomes.

Methods

Institution based cross-sectional study was conducted among pregnant women to assess the prevalence of anemia and its association with dietary diversity in Hossana Town from March 15 to April 30, 2017. Systematic random sampling procedure was employed to select 314 study subjects. Data were collected using an interviewer administered semi-structured questionnaire supplemented with laboratory tests. Multivariable logistic regression was used to determine the independent predictors of anemia.

Results

The prevalence of mild to moderate anemia among pregnant women was 56.6% and 40.8% respectively. The mean dietary diversity and food variety score of study participants were 7 and 22 respectively. Maternal education (AOR=10.5; 95% CI:2.2, 27), occupation of spouse (AOR=9.3; 95% CI:1.6, 53), nutrition education (AOR=2.5; 95% CI:1.5, 6.4) and dietary diversity (AOR=18.6; 95% CI: 4.4, 28) were significantly associated with anemia.

Conclusion

Anemia was found to be a moderate public health problem in Hossana Town. Therefore, there is a need of nutrition education and promotion awareness on healthy diets to prevent anemia among pregnant women.

A Nutrition Education Intervention to Increase Consumption of Pulses Showed Improved Nutritional Status of Adolescent Girls in Halaba Special District, Southern Ethiopia

This study aimed to determine the effect of a 6-month in-school nutrition education intervention to improve pulse consumption on weight status of adolescent girls in Ethiopia. At the intervention school, 66 girls received bi-monthly lessons that included recipes and tastings. Girls (n = 66) at the control school had usual in-school activities. With pulse-based nutrition education which included discussions and demonstrations, knowledge, attitude and practice scores improved (p < 0.001) in the intervention group while control scores remained low and unchanged. Prevalence of underweight, measured as Body Mass Index (BMI) for age, decreased with the education intervention, from 13.6% to 3% (p = 0.004), while there was no significant change seen in control girls. In Ethiopia, equipping girls in schools with the knowledge and skills to improve food intake by consuming locally grown pulses may mitigate underweight in Ethiopian female adolescents.

Impacts of Caregivers’ Nutrition Knowledge and Food Market Accessibility on Preschool Children’s Dietary Diversity in Remote Communities in Southeast Nigeria

Empirical evidence is scanty on the nexus between caregivers’ nutrition knowledge, market accessibility, and preschool children’s dietary diversity in remote communities of Africa’s most populous country, Nigeria. To fill this gap, this study evaluated the effects of caregivers’ nutrition knowledge and access to food market on dietary diversity of preschool children. We used cross-sectional data from four hundred households selected from twenty remote communities in Southeast Nigeria. The study adopted instrumental variable regression to estimate the impacts of nutrition knowledge and food market access on preschool children’s dietary diversity. The findings show that in remote communities, caregivers’ nutrition knowledge and households’ closeness to the market improved preschool children’s dietary diversity. The study demonstrates the potential of improving preschool children’s nutrition outcomes through enhancing access to food market and the nutrition knowledge of the caregivers.

Dietary Diversity among Preschoolers: A Cross-Sectional Study in Poor, Rural, and Ethnic Minority Areas of Central South China

The aim of this study was to document the dietary diversity status of preschool children in poor, rural, and ethnic minority areas of Central South China and examine its associated factors both at home and in preschools. A cross-sectional study including 1328 preschool children aged three or five years from two nationally designated poverty counties in Hunan Province was conducted. A dietary diversity score (DDS) was constructed to measure the dietary patterns based on the 24 h recall method. The mean DDS among the sample children was 5.77 (95% confidence interval: 5.70⁻5.83, range 1 to 9) with a standard deviation of 1.22. Both household characteristics (including the education level of the child's primary caregiver and the nutritional knowledge of the caregiver) and preschool factors (including the nutritional knowledge of the child's preschool principal and teachers, nutritional training to children, and the preschool kitchen manager) were positively associated with children's DDS. The dietary diversity status of children in poor, rural, and ethnic minority areas of Central South China is much lower than that of their peers in other areas. Nutritional education should be provided to caregivers, preschool staff, and children to narrow the gap.

Evidence-based interventions for improvement of maternal and child nutrition in low-income settings: what's new?

PURPOSE OF REVIEW

Maternal and child malnutrition continues to disproportionately affect low and middle-income countries, contributing to high rates of morbidity, mortality, and suboptimal development. This article reviews evidence from recent systematic reviews and studies on the effectiveness of interventions to improve nutritional status in these especially vulnerable populations.

RECENT FINDINGS

Macronutrients provided to expectant mothers in the form of balanced protein energy supplements can improve fetal growth and birth outcomes, and new research suggests that lipid nutrient supplements can reduce both stunting and wasting in newborns. Maternal multiple micronutrient supplementations can also improve fetal growth, and reduce the risk of stillbirth. Nutrition education and supplementation provided to pregnant adolescents can also improve birth outcomes in this vulnerable population. New evidence is broadening our understanding of the development of gut microbiota in malnourished infants, and the possible protective role of breastmilk.

SUMMARY

The reviewed evidence on nutrition interventions reinforces the importance of packaging interventions delivered within critical windows throughout the life course: before conception, during pregnancy, and throughout childhood. Emerging evidence continues to refine our understanding of which populations and contexts benefit from which intervention components, which should allow for more nuanced and tailored approaches to the implementation of nutrition interventions.
