Trends in burden and risk factors associated with childhood stunting in Rwanda from 2000 to 2015: policy and program implications

Women's exposure to intimate partner violence and its association with child stunting: findings from a population-based study in rural Rwanda

BACKGROUND

Child stunting is a significant challenge for most districts in Rwanda and much of sub-Saharan Africa and persists despite multisectoral efforts. There is a notable lack of population-based studies examining the correlation between violence against women and child stunting in Rwanda.

OBJECTIVE

We aimed to investigate the association between Rwandan women's exposure to intimate partner violence (IPV) and child stunting in children under 3 years of age.

METHODS

In December 2021, a population-based cross-sectional study was conducted in the Northern Province of Rwanda, including 601 women and their children <3 years of age. The World Health Organization (WHO) Women's Health and Life Experiences Questionnaire for IPV research was utilized. Child stunting was assessed using the WHO criteria for low height for age. Multivariable logistic regression was used to examine the association between IPV and child stunting before and during pregnancy.

RESULTS

Of 601 women, 47.4% (n = 285) experienced any form of IPV during pregnancy. The prevalence rates of the types of IPV associated with child stunting varied: 33% for psychological, 31.4% for sexual, and 25.7% for physical violence. Exposure to physical violence before pregnancy and sexual violence during pregnancy was associated with higher odds of child stunting; the adjusted odds ratios were 1.29 (95% CI, 1.01-2.03) and 1.25 (95% CI, 1.04-2.01), respectively.

CONCLUSION

Women's exposure to physical and psychological violence is associated with an increased risk of child stunting. Urgent targeted interventions and support systems are needed to address the complex relationship between women's exposure to IPV and adverse effects on child growth.

Maternal factors promoting normal linear growth of children from impoverished Rwandan households: a cross-sectional study

BACKGROUND

Linear growth faltering remains a pervasive public health concern that affects many children worldwide. This study aimed to investigate possible maternal factors promoting normal linear growth among children aged 6-23 months of age from impoverished Rwandan households.

METHODS

We used a three-stage cluster sampling procedure. The study population consisted of children aged six to 23 months and their mothers who lived in the study districts. A structured questionnaire helped to collect data from 807 selected mother-child dyads. The primary outcome variable was height-for-age Z scores. The main predictors were maternal income-generating activity, maternal education, maternal depression, household decision making, number of ANC visits, use of family planning method, types of family planning, and mode of delivery. We used univariate analysis to establish median, frequencies, and percentages. Furthermore, we used the Kruskal-Wallis, Mann-Whitney U, and Spearman rank correlation tests for bivariate analysis. We included in the final model of robust linear regression for multivariate analysis the potential confounding variables identified as significantly associated with the outcome (child age, participation in works for both parents, good handwashing practice, owning a vegetable garden, and the total number of livestock) along with maternal factors.

RESULTS

Maternal factors that promoted normal linear growth of children were the presence of maternal income generation activity (β= 0.640 [0.0269 1.253], p value = 0.041), the participation of the mother in the decision-making process of the household (β=0.147 [0.080 0.214], p-value < 0.001), and the higher frequency of consultations with ANC (β=0.189 [0.025 0.354], p-value = 0.024). Additionally, a combination of household decision-making with the number of ANC visits predicted an increase in the linear growth of the child (β=0.032 [0.019 0.045], p-value < 0.001).

CONCLUSION

Maternal factors such as maternal income-generating activity, maternal participation in household decision making, and increased number of ANC visits were found to promote normal child linear growth. These results contribute valuable information to the formulation of interventions and policies to improve child nutrition and growth in the community studied.

Prevalence of childhood stunting and determinants in low and lower-middle income African countries: Evidence from standard demographic and health survey

INTRODUCTION

Undernutrition poses a significant global public health challenge, adversely affecting childhood cognitive and physical development while increasing the risk of disease and mortality. Stunting, characterized by impaired growth and development in children due to insufficient psychological stimulation, frequent infections, and inadequate nutrition, remains a critical issue. Although economic growth alone cannot fully address the prevalence of stunting, there exists a robust correlation between a country's income level and childhood stunting rates. Countries with higher incomes tend to have lower rates of childhood stunting. Notably, while childhood stunting is declining worldwide, it remains persistent in Africa. Consequently, this study aims to assess the prevalence of childhood stunting and its determinants in low- and lower-middle-income African countries.

METHOD

This study conducted a secondary analysis of standard demographic and health surveys in low- and lower-middle-income African countries spanning the period from 2010 to 2022. The analysis included a total sample of 204,214 weighted children under the age of five years. To identify the determinants of stunting, we employed a multilevel mixed-effect model, considering the three levels of variables. The measures of association (fixed effect) were determined using the adjusted odds ratio at a 95% confidence interval. Significance was declared when the association between the outcome variable and the explanatory variable had a p-value less than 0.05.

RESULT

In low and lower-middle-income African countries, 31.28% of children under five years old experience stunting, with a 95% confidence interval ranging from 31.08% to 31.48%. The results from a multilevel mixed-effect analysis revealed that 24 months or more of age of child, male gender, low and high birth weight, low and high maternal BMI, no and low maternal education, low household wealth index, multiple (twin or triplet) births, rural residence, and low income of countries were significantly associated with childhood stunting.

CONCLUSION

Stunting among children under five years of age in low- and lower-middle-income African countries was relatively high. Individual, community, and country-level factors were statistically associated with childhood stunting. Equally importantly, with child, maternal, and community factors of stunting, the income of countries needs to be considered in providing nutritional interventions to mitigate childhood stunting in Africa.

Leveraging multisectoral approach to understand the determinants of childhood stunting in Rwanda: a systematic review and meta-analysis

BACKGROUND

Addressing childhood stunting is a priority and an important step in the attainment of Global Nutrition Targets for 2025 and Sustainable Development Goals (SDGs). In Rwanda, the prevalence of child stunting remains high despite concerted efforts to reduce it.

METHODS

Utilizing the United Nations International Children's Emergency Fund (UNICEF) framework on maternal and child nutrition, this study systematically evaluated the determinants of child stunting in Rwanda and identified available gaps. Twenty-five peer-reviewed papers and five Demographic and Health Surveys (DHS) reports were included in the final selection of our review, which allowed us to identify determinants such as governance and norms including wealth index, marital status, and maternal education, while underlying determinants were maternal health and nutrition factors, early initiation of breastfeeding, water treatment and sanitation, and immediate factors included infections.

RESULTS

A total of 75% of the overall inequality in stunting was due to the difference in the social determinants of stunting between poor and nonpoor households. Maternal education (17%) and intergenerational transfer (31%) accounted for most of the inequalities in stunting, and an increase in gross domestic product per capita contributed to a reduction in its prevalence. There is a paucity of information on the impact of sociocultural norms, early life exposures, maternal health and nutrition, and Rwandan topography.

CONCLUSION

The findings of this study suggest that improving women's status, particularly maternal education and health; access to improved water, sanitation, and hygiene-related factors; and the socioeconomic status of communities, especially those in rural areas, will lay a sound foundation for reducing stunting among under-5 children.

Socioeconomic disparities in Rwanda's under-5 population's growth tracking and nutrition promotion: findings from the 2019-2020 demographic and health survey

BACKGROUND

Regular growth monitoring can be used to evaluate young children's nutritional and physical health. While adequate evaluation of the scope and quality of nutrition interventions is necessary to increase their effectiveness, there is little research on growth monitoring coverage measurement. The purpose of this study was to investigate socioeconomic disparities in under-5 Rwandan children who participate in growth monitoring and nutrition promotion.

METHODS

We used data from the 2019-2020 Rwanda Demographic and Health Survey (RDHS), which included 8092under-5 children. Percentage was employed in univariate analysis. To examine the socioeconomic inequalities, concentration indices and Lorenz curves were used in growth monitoring and nutrition promotion among under-5 children.

RESULTS

A weighted prevalence of 33.0% (95%CI: 30.6-35.6%) under-5 children growth monitoring and nutrition promotion was estimated. Growth monitoring and nutrition promotion among under-5 children had higher uptake in the most disadvantaged cohort, as the line of equality sags below the diagonal line in Lorenz curve. Overall, there was pro-poor growth monitoring and nutrition promotion among under-5 in Rwanda (Conc. Index = 0.0994; SE = 0.0111). Across the levels of child and mother's characteristics, the results show higher coverage of under-5 growth monitoring and nutrition promotion in the most socioeconomic disadvantaged cohort.

CONCLUSION

The study found a pro-poor disparity in growth monitoring and nutrition promotion among under-5 children in Rwanda. By implication, the most disadvantaged children had a higher uptake of growth monitoring and nutrition promotion. The Rwanda government should develop policies and programmes to achieve the universal health coverage for the well-off and underserved population.

Socio-demographic and environmental determinants of under-5 stunting in Rwanda: Evidence from a multisectoral study

Child stunting is an important household, socio-economic, environmental and nutritional stress indicator. Nationally, 33% of children under 5 in Rwanda are stunted necessitating the need to identify factors perpetuating stunting for targeted interventions. Our study assessed the individual and community-level determinants of under-5 stunting essential for designing appropriate policy and program responses for addressing stunting in Rwanda. A cross-sectional study was conducted between September 6 and October 9, 2022, in five districts of Rwanda including, Kicukiro, Ngoma, Burera, Nyabihu and Nyanza. 2788 children and their caregivers were enrolled in the study and data on the individual level (child, caregiver/household characteristics), and community-level variables were collected. A multilevel logistic regression model was used to determine the influence of individual and community-level factors on stunting. The prevalence of stunting was 31.4% (95% CI: 29.5–33.1). Of this, 12.2% were severely stunted while 19.2% were moderately stunted. In addition, male gender, age above 11 months, child disability, more than six people in the household, having two children below the age of five, a child having diarrhea 1–2 weeks before the study, eating from own plate when feeding, toilet sharing, and open defecation increased the odds of childhood stunting. The full model accounted for 20% of the total variation in the odds of stunting. Socio-demographic and environmental factors are significant determinants of childhood stunting in Rwanda. Interventions to address under-five stunting should be tailored toward addressing individual factors at household levels to improve the nutritional status and early development of children.

Prevalence and Correlates of Stunting among Children Aged 6-23 Months from Poor Households in Rwanda

Stunted linear growth continues to be a public health problem that overwhelms the entire world and, particularly, developing countries. Despite several interventions designed and implemented to reduce stunting, the rate of 33.1% is still high for the proposed target of 19% in 2024. This study investigated the prevalence and associated factors of stunting among children aged 6-23 months from poor households in Rwanda. A cross-sectional study was conducted among 817 mother-child dyads (two individuals from one home) living in low-income families in five districts with a high prevalence of stunting. Descriptive statistics were used to determine the prevalence of stunting. In addition, we used bivariate analysis and a multivariate logistic regression model to measure the strength of the association between childhood stunting and exposure variables. The prevalence of stunting was 34.1%. Children from households without a vegetable garden (AOR = 2.165, p-value < 0.01), children aged 19-23 months (AOR = 4.410, p-value = 0.01), and children aged 13-18 months (AOR = 2.788, p-value = 0.08) showed increased likelihood of stunting. On the other hand, children whose mothers were not exposed to physical violence (AOR = 0.145, p-value < 0.001), those whose fathers were working (AOR = 0.036, p-value = 0.001), those whose parents were both working (AOR = 0.208, p-value = 0.029), and children whose mothers demonstrated good hand washing practice (AOR = 0.181, p-value < 0.001) were less likely to be stunted. Our findings underscore the importance of integrating the promotion of handwashing practices, owning vegetable gardens, and intimate partner violence prevention in the interventions to fight child stunting.

Measuring the Uptake of Growth Monitoring and Nutrition Promotion among under-5 Children: Findings from the Rwanda Population-Based Study

Regular growth monitoring can be used to evaluate the nutritional and physical health of children. Ample evaluation of the reach and quality of nutrition interventions is necessary to increase their effectiveness, but there is little research on improving coverage measurement. The aim of this study was to explore the coverage of growth monitoring, nutrition promotion, and associated factors by Rwandan caregivers of children under the age of five. Data from 2019−2020 Rwanda Demographic and Health Survey with a total of 8092 children under the age of five were used for this study. Prevalence of growth monitoring and nutrition promotion were reported and the factors influencing this were evaluated using multivariable logistic regression model. The prevalence of growth monitoring and nutrition promotion among under-5 children was 33.0% (95%CI: 30.6−35.6%). Older children, caregivers who were native residents, those with a health insurance, in a marital relationship, employed, and residing in rural areas had higher odds to participate in growth monitoring and nutrition promotion compared to their counterparts. Rwanda has a low rate of coverage for growth monitoring and nutrition promotion among children <5 and public health nutrition interventions should prioritize nutritional counseling as well as the availability of growth monitoring and promotion services.

Does birth season correlate with childhood stunting? An input for astrological nutrition

INTRODUCTION

Chronic malnutrition is highly prevalent in Sub-Saharan Africa and a severe public health problem in Ethiopia.At country level in the past three decades,the prevalence of stunting is above 40%.Different researchs and intervention were implemented in the past;but the progresss is non-remarkable.Despite; the effect of birth season on childhood chronic malnutrition was not studied yet in Ethiopia.

METHODS

This research was extracted from the 2016 demographic health survey of Ethiopia. The data was collected based on national and international scientific protocols. A total of 645 enumeration areas were selected for the national survey.The surevey uses two stage stratified sampling technique to gather data from the sampling unit. After excluding non eligible children a total of 8855 participants were included for final analysis.Height and weight were measured based on the standards nutritional assessment procedure.SPSS version 20 was used to analyze the data.Descriptive statistics were used to present the data. Binary and multivariable logistic regression models were regressed to identify the potential predictors.A p-value of less than 0.05 with 95% CI were used to declare an association.

RESULT

The prevalence of stunting in Ethiopia was 38.7% (95% CI: 36.8, 40.6). Season of birth had a significant association with stunting. The odds of being stunted among children born in the spring season were decreased by 16% as compared to children born in the winter season.

CONCLUSION

Children born in the spring season were less likely to be stunted (the so called October effect). The clear scientific relation between the season of birth and child anthropometric indicator is not well understood. Nutritional interventions and policies are better to consider the birth season of the child.

Inequalities in childhood stunting: evidence from Sudan multiple indicator cluster surveys (2010-2014)

Background

Leaving no one behind has been an important marker of the Sustainable Development Goals. Closing the gap in malnutrition between children of different backgrounds aligns well with the tenet of this international agenda. To this end, high-quality evidence of the magnitude and trends of socioeconomic and geographic related existing inequalities in the childhood stunting among Sudanese children emanate from this study help for policy maker and planners to design and implement effective interventions to narrow down inequality.

Methods

We used the World Health Organization’s (WHO) Health Equity Assessment Toolkit (HEAT) for our analysis of stunting inequality. Following standard equity analysis methods recommended by the WHO, we performed the disaggregated analysis of stunting across five equity stratifiers: Wealth, education, residence, sex, and sub-national regions. Then, we summarized stunting inequality through four measures of inequality: Difference, Ratio, Slope Index of Inequality (SII), and Relative Index of Inequality (RII). The point estimates of stunting were accompanied by 95% confidence intervals to measure the statistical significance of the findings.

Results

In this study, the national average childhood stunting prevalence was increased by 4% from 2010 to 2014. The findings revealed stark inequalities in stunting in all the studied dimensions of inequality. Huge inequality has existed along the wealth quintiles. Simple difference measure for education was increased by four points and simple relative measure decreased by one point for economic status.

Conclusions

Sex, residence and, geographically related inequalities remain unchanged over time, while economic status and educational inequality had seen a change by some inequality measures over the same time period.

Potential Role of African Fermented Indigenous Vegetables in Maternal and Child Nutrition in Sub-Saharan Africa

Hunger and malnutrition continue to affect Africa especially the vulnerable children and women in reproductive age. However, Africa has indigenous foods and associated traditional technologies that can contribute to alleviation of hunger, malnutrition, and communicable and noncommunicable diseases. The importance of African indigenous vegetables is undeniable, only that they are season-linked and considered as "food for poor" despite their high nutritional contents. The utilization of African indigenous vegetables (AIVs) is hindered by postharvest losses and antinutrients affecting the bioavailability of nutrients. In Africa, fermentation is among the oldest food processing technologies with long history of safe use. Apart from extending shelf life and improving food organoleptic properties, fermentation of African indigenous vegetables (AIVs) is known to improve food nutritional values such as proteins, minerals, vitamins, and other beneficial phytochemicals. It can also increase bioavailability of various vitamins, minerals, and phytochemicals and increase synthesis of vital blood pressure regulators thus protecting against cardiovascular diseases and cancer and further helping fight certain malnutrition deficiencies. Some lactic acid bacteria (LAB) involved in food fermentation are known to produce exopolysaccharides with cholesterol-lowering, immunomodulator, antioxidant, and anticancer properties. Fermented foods (vegetables) are superior in quality and safety since most microorganisms involved in fermentation are good starter cultures that can inhibit the growth of foodborne pathogens and detoxify harmful compounds in foods. Thus, fermented foods can boost growth and well-being in children and women due to their higher nutritional contents. Therefore, fermentation of AIVs can contribute to the attainment of food and nutrition security especially among women and children who rely on these vegetables as a staple source of micronutrients and income. These benefits have a positive impact on the implementation of the second sustainable development goals and African Union agenda 2063. This review is aimed at shedding light on the potential of African fermented indigenous vegetables in combating maternal and child malnutrition in Sub-Sahara Africa.

Household, dietary and healthcare factors predicting childhood stunting in Ethiopia

Stunting, decidedly prevalent in Ethiopia, is a reduction of linear growth associated with a series of adverse consequences. However, little is known about its determinants and factors associated in Ethiopia and elsewhere. Therefore, this study aimed to determine major undelying factors associated with risk of stunting among under-five children in Ethiopia. We used the 2016 Ethiopian Demographic and Heath Survey (EDHS) data and analysed a total of 11,023 children aged 0–59 months' data. Bivariate and multivariate logistic regression were fitted to identify key predictors and factors associated with stunting. Results show that, household and demographic factors such as maternal education (AOR: 0.67, 95% CI: 0.51, 0.89), wealth index (AOR: 0.65 (0.54, 0.78), sex of child (AOR: 0.78 (0.72, 0.85), possession of refrigerator (AOR: 0.57 (0.36, 0.89), possession of television and others like twin birth, house main floor material, types of cooking fuel were significantly association with stunting. Among dietary factors, early initiation of breast feeding; feeding powdered or fresh milk (AOR: 0.63 (0.52, 0.76); formula feeding (AOR: 0.41 (0.21, 0.81); consumption of organ meat(s) (AOR: 0.52 (0.32, 0.85) and beta-carotene rich fruits and vegetables were significantly associated lower odds of stunting. Antenatal care (ANC) follow-up, deworming during pregnancy (AOR : 0.11 (0.02, 0.74), institutional delivery (AOR : 0.64 (0.58, 0.71) and birth size (AOR: 5.1 (1.64, 15.88) were among the health care factors associated with stunting of under-five children. In conclusion, stunting is modulated by several household, dietary and healthcare factors, both at household and community-level. Likewise; improving household income, women empowerment, dietary diversity among mothers and children and improving maternal health care system are critical to mitigate under-five stunting more rapidly.

An empirical study of factors associated with height-for-age z-scores of children aged 6-23 months in northwest Rwanda: the role of care practices related to child feeding and health

We aimed to identify the factors influencing child height-for-age z-scores (HAZ) as a measure of child nutritional status in Rwanda, and to examine the role of child feeding and health practices. We conducted a cross-sectional study involving 379 children (aged 6-23 months) and their mothers in northwest Rwanda. Data were collected using a pre-tested, structured questionnaire. An infant and young child feeding practices index (ICFI) and health practices index (HPI) were developed and categorised into tertiles, and linear regression analyses were performed to assess their association with child HAZ. Overall, mothers of non-stunted children exhibited better feeding and health practices than those of stunted children. ICFI was positively associated with child HAZ. We found an adjusted mean HAZ difference of 0·14 between children whose mothers were in high ICFI tertile compared with those in low tertile. Neither HPI nor any of its components were significantly associated with child HAZ. Other factors that were positively associated with child HAZ were infant birth weight (P < 0·001) and maternal height (P < 0·001). Child age, sex (male) (P < 0·05) and altitude (P < 0·05) were negatively associated with child HAZ. Diarrhoea (P < 0·05) and respiratory infections (P < 0·05) were negatively associated with HAZ in younger children aged 6-11 months. Policies to reduce stunting in this population must focus on both pre- and postnatal factors. Appropriate child feeding practices, particularly breast-feeding promotion and improvement in children's dietary diversity combined with measures to control infections should be given priority.
