Commercial Snack Food and Beverage Consumption Prevalence among Children 6-59 Months in West Africa

Child feeding practices in rural Ethiopia show increasing consumption of unhealthy foods

The quality of complementary feeding can have both short- and long-term health impacts by delaying or promoting child growth and establishing taste preferences and feeding behaviours. We aimed to assess the healthy and unhealthy feeding practices of infants and young children in rural Ethiopia. We conducted two rounds of surveys in December 2017/18 in Habru district, North Wello, rural Ethiopia among caregivers of infants and young children (N = 574). We characterised the consumption of infants and young children using non-quantitative 24 h recall and the World Health Organization infant and young child feeding indicators. Sociodemographic characteristics, anthropometry and haemoglobin concentrations were assessed. Breastfeeding was a norm as 82% and 67% were breastfed in the first and second rounds. Between the two rounds, dietary diversity increased from 5% to 17% (p < 0.05), but more pronounced increases were observed in the consumption of ultra-processed food (UPFs). Up to one-in-five (22%) of the children consumed UFPs. With an average of only three food groups consumed, the consumption of nutrient-dense foods like animal source foods, fruits and vegetables was very low particularly among younger children. UPFs are an additional risk factor that contributes to poor quality diets. Behavioural Change Communication interventions, including those in rural areas, should explicitly discourage the consumption of UPFs. Future studies should aim to quantify the amount of UPFs consumed and evaluate how this is associated with diet adequacy and nutritional outcomes.

Unhealthy food consumption and its determinants among children aged 6 to 23 months in sub-Saharan Africa: a multilevel analysis of the demographic and health survey

BACKGROUND

Unhealthy food consumption that begins early in life is associated with a higher risk of nutrient inadequacy and related chronic diseases later in life. Healthy eating and consumption of important nutrients help to maintain a healthy body weight and reduce the risk of developing chronic conditions. Research from sub-Saharan Africa regarding consumption of unhealthy foods remains limited, with no studies quantifying the pooled prevalence among young children. Therefore, this study is intended to assess the pooled prevalence and determinants of unhealthy food consumption among children aged 6 to 23 months.

METHODS

Data from the most recent demographic and health surveys of five countries in sub-Saharan Africa conducted between 2015 and 2022 were used. A total weighted sample of 16,226 children aged 6 to 23 months was included in the study. Data extracted from DHS data sets were cleaned, recorded, and analyzed using STATA/SE version 14.0 statistical software. Multilevel mixed-effects logistic regression was used to determine the factors associated with the dependent variable. Intra-class correlation coefficient, likelihood ratio test, median odds ratio, and deviance (-2LLR) values were used for model comparison and fitness. Finally, variables with a p-value < 0.05 and an adjusted odds ratio with a 95% confidence interval were declared statistically significant.

RESULTS

The pooled prevalence of unhealthy food consumption among children aged 6 to 23 months was 13.41% (95% CI: 12.89-13.94%). Higher consumption of unhealthy foods was reported among mothers with low education [adjusted odds ratio (AOR) = 0.37; 95% confidence interval (CI) (0.30, 0.46)], unmarried women [AOR = 1.19; 95% CI (1.05, 1.34)], who had no media exposure [AOR = 0.64; 95% CI (0.56, 0.72)], delivered at home [AOR = 0.74; 95% CI (0.62, 0.87)], who hadn't had a PNC checkup [AOR = 0.66; 95% CI (0.60, 0.73)], wealthier households [AOR = 1.20; 95% CI (1.05, 1.37)], older children (aged ≥ 9 months) [AOR = 3.88; 95% CI (3.25, 4.63)], and low community level media exposure [AOR = 1.18; 95% CI (1.04, 1.34)].

CONCLUSION

Nearly one out of seven children aged 6 to 23 months consumed unhealthy foods. Maternal educational level, marital status of the mother, exposure to media, wealth index, place of delivery, PNC checkup, and the current age of the child were factors significantly associated with unhealthy food consumption. Therefore, improving women's education, disseminating nutrition-related information through the media, providing more attention to poor and unmarried women, and strengthening health facility delivery and postnatal care services are recommended.

Barriers to appropriate complementary feeding and the use of ultra-processed foods: A formative qualitative study from rural Oromia, Ethiopia

Children's consumption of ultra-processed foods (UPF) is increasing in Ethiopia, but relatively little is known about the specific feeding practices that underlie this pattern. The objective of this study was to explore patterns of consumption of UPF by infants and young children within a broader context of inappropriate complementary feeding practices in extremely poor households in rural Oromia, Eastern Ethiopia. A formative qualitative study was conducted using semistructured interview questionnaires developed drawing on a socioecological model. A total of 16 focus group discussions with mothers (45 respondents), fathers (21 respondents) and grandmothers (23 respondents) of children aged 6-23 months in households that were beneficiaries of the Productive Safety Net Program were conducted, along with four key informant interviews with health workers. Qualitative transcripts were complemented with field notes before qualitative content analysis was applied. The key findings suggest that UPF were widely provided to infants and young children as part of a pattern of suboptimal complementary feeding, including both early and late initiation of complementary foods. In particular, UPF (including juice, biscuits and lipid-based nutrient supplements) were diluted with or dissolved in water and fed to infants via bottle, often before the recommended age of initiation of 6 months. Mothers and caregivers reported that they perceived the products to be affordably priced and packaged, ready to use and convenient given their time constraints. The level of consumption of UPF and its effects on infant and young child feeding feeding practices and children's nutritional status in rural Ethiopia should be further explored.

Prevalence and contributing factors of anaemia among children aged 6-24 months and 25-59 months in Mali

Although considerable global initiatives have been undertaken to tackle anaemia, its prevalence continues to be high in sub-Saharan African nations. In Mali specifically, anaemia represents a significant and pressing public health issue. The purpose of the present study was to examine the key risk factors related to anaemia among children aged 6-24 months (younger age group) and 25-59 months (older age group). We used the Mali 2018 Demographic and Health Survey data, collected from 8861 mothers with children under five. Logistic regression was used to assess the risk factors for childhood anaemia. The results suggest that the prevalence of anaemia was 88 % in the younger and 76 % in the older age groups. The risk factors unique to the younger age group were malaria (OR 4⋅05; CI 0⋅95, 11⋅3) and place of residence (OR 0⋅55; CI 0⋅32, 0⋅94), while for the older age group, they were morbidity (OR 1⋅91; CI 1⋅12, 3⋅24), drinking from a bottle (OR 1⋅52; CI 1⋅04, 2⋅22), and micronutrient intake (OR 0⋅61; CI 0⋅40, 0⋅91). Risk factors that significantly contributed to both age groups include breastfeeding, deworming, maternal anaemia, maternal education, and wealth index. Anaemia also varied by region. The widespread prevalence of anaemia can be attributed to a multitude of factors. In addressing this issue, it is imperative to acknowledge the unique characteristics of specific regions and rural areas, where the incidence of anaemia surpasses the national average. Therefore, any intervention efforts should be tailored to the specific needs and challenges of these areas.

Temporal Dietary Diversity Patterns Are Associated with Linear Growth but Not Ponderal Growth in Young Children in Rural Vietnam

BACKGROUND

The first 2 y of life mark critical changes in children's diet from milk-based food to diverse food rich in taste and texture, but few studies in low-resource settings have explored the changes in diet quality during this period.

OBJECTIVES

We examine temporal dietary diversity patterns between 6 and 25 mo of age and their associations with child growth outcomes in rural Vietnam.

METHODS

We used data from a prospective cohort (PRECONCEPT) and included 781 children that had dietary diversity data for 4 age windows: 6-8, 11-13, 17-19, and 23-25 mo of age. The temporal dietary diversity patterns were constructed by tracking how minimum dietary diversity changed over the 4 age windows. Multivariate logistic and linear regressions were used to assess the associations of dietary patterns with stunting and wasting at the 23-25 mo window and with relative linear and ponderal growth between 6 and 25 mo, respectively.

RESULTS

Two key aspects of diet quality (the introduction and the stability of diverse diet) were used to define 5 temporal dietary diversity patterns: timely-stable (30% of the sample), timely-unstable (27%), delayed-stable (16%), delayed-unstable (15%), and super-delayed (12%). Compared with timely-stable pattern (the most optimal pattern), timely-unstable and super-delayed patterns were associated with a higher risk of stunting (odds ratio [OR]: 1.78; 95% confidence interval [CI]: 1.05, 3.04 and OR: 1.98; 95% CI: 1.02, 3.80, respectively) and slower linear growth (β: -0.24; 95% CI: -0.43, -0.06 and β: -0.25; 95% CI: -0.49, -0.02, respectively). No associations were found for wasting and relative ponderal growth.

CONCLUSIONS

Delayed introduction of a diverse diet and failure to maintain a diverse diet are associated with slower linear growth but not ponderal growth in the first 2 y of age. This trial was registered at clinicaltrials.gov as NCT01665378.

Unhealthy food consumption and its associated factors among infants and young children in Gondar city, northwest Ethiopia: a community based cross sectional study

INTRODUCTION

Many low- and middle-income countries are now shifting toward diets that are higher in added sugars, unhealthy fats, salt, and refined carbohydrates. Childhood obesity and chronic diseases have all been linked to unhealthy food consumption. Despite this, the majority of Ethiopian infants and children consume unhealthy food. There is also a scarcity of evidence. Therefore, the objective of this study was to assess the prevalence of unhealthy food consumption and its associated factors among children ages 6-23 months in Gondar City, northwest Ethiopia.

METHODS

A community-based cross-sectional study was conducted from June 30 to July 21, 2022, in Gondar city. Multistage sampling was used to select 811 mother-child pairs. Food consumption was measured through a 24-hour recall. Data were entered into EpI Data 3.1 before being exported to STATA 14 for further analysis. A multivariable logistic regression analysis was employed to identify the factors associated with unhealthy food consumption. An adjusted odds ratio (AOR) with a 95% confidence interval was used to show the strength of the association, while a P-value of 0.05 was used to declare the significance of the association.

RESULTS

The percentage of children with unhealthy food consumption was 63.7% (95% CI: 60.4%, 67.2%). Maternal education [AOR = 1.89, 95% CI = 1.05, 3.69], living in an urban residence [AOR = 4.55, 95% CI = 3.61, 7.78], GMP service [AOR = 2.07, 95% CI = 1.48, 3.18], age of the child 18-23 months [AOR = 0.53, 95% CI = 0.34, 0.74], and family size of more than four [AOR = 1.22, 95% CI = 1.07, 2.78] were significantly associated with unhealthy food consumption.

CONCLUSION

In Gondar City, nearly two thirds of infants and children received unhealthy food. Maternal education, urban residence, GMP service, child age, and family size were all significant predictors of unhealthy food consumption. Thus, improving the uptake of GMP services and family planning services is critical to reducing unhealthy food consumption.

Nutrient Profiles of Commercially Produced Complementary Foods Available in Burkina Faso, Cameroon, Ghana, Nigeria and Senegal

The nutritional quality of commercially produced complementary food (CPCF) varies widely, with CPCF in high-income settings often containing excessive levels of sugar and sodium. Little is known about the nutritional quality of CPCF available in the West Africa region, despite their potential to improve the nutrition of infants and young children (IYC). This study evaluated the nutritional quality of CPCF available in five West African countries using the WHO Europe nutrient profiling model (NPM) and assessed their suitability for IYC based on label information. The proportion that would necessitate a "high sugar" warning was also determined, and the micronutrient (iron, calcium, and zinc) content was assessed against IYC-recommended nutrient intakes. Of the 666 products assessed, only 15.9% were classified as nutritionally suitable for promotion for IYC. The presence of added sugar and excessive sodium levels were the most common reasons for a product to fail the nutrient profiling assessment. Dry/instant cereals contributed the highest percentage of recommended nutrient intake (RNI) per serving. This highlights the need for policies to improve the nutritional quality of CPCF in West Africa, including labeling standards and the use of front-of-pack warning signs to promote product reformulation and clearly communicate nutritional quality to caregivers.

Micronutrient intake of children in Ghana and Benin: Estimated contribution of diet and nutrition programs

We estimated how micronutrient needs of young children, aged 6-24 months were covered by the standard (traditional) diets in Ghana and Benin, and the contributions of partial breastfeeding and national nutrition programs aimed at improving micronutrient status to overall micronutrient intakes. Estimates of micronutrient intake from standard diets were based on previous surveys, using the food composition table of West Africa (INFOOD). Recommended micronutrient intakes were based on World Health Organization recommendations. Children were grouped in three age groups (6-8, 9-12, and 13-24 months) to capture the changing dynamics of the complementary feeding period. As expected, from 6 months of age onwards, breastmilk didn't cover the micronutrient needs. The standard diets contributed only minimal to micronutrient intakes of children ranging from 0% to 37% of recommended intakes for Ca, Fe, Zn, vitamin A, vitamin D and iodine depending on the micronutrient considered. The contribution of mass (bio)-fortification programs to the coverage of micronutrient needs varied widely, depending on the staple food considered and the country, but overall did not allow to fill the gap in micronutrient needs of children except for vitamin A in some contexts. In contrast, consumption of voluntary fortified complementary food, especially formulated for the needs in this age groups, contributed substantially to overall micronutrient intake and could fill the gap for several micronutrients. The development of young child-targeted programs including micronutrient-dense foods, associated with interventions to increase the diet diversity and meal frequency, could significantly improve micronutrients intakes of children in both Ghana and Benin.

Developing a culturally acceptable peanut nutrition bar with smallholder women farmers in Kaffrine, Senegal using response surface methodology

To increase farm income and food security, a collaboration was made with smallholder women farmers in Kaffrine, Senegal to develop a culturally acceptable peanut nutrition bar using healthy indigenous and local ingredients and feasible manufacturing methods. This study aimed to use response surface methodology to optimize the bar's formulation and characterize the texture, nutrient profile, sensory qualities, and water activity. The bars were made by varying the ratio of cowpea flour to corn flour (w/w, d.b., 0/100, 25/75, 50/50, 75/25, and 100/0) and the percentage of baobab pulp powder in the cowpea-corn flour blend (w/w, d.b., 15%, 20%, 25%, and 30%) with a fixed amount of 13 g of peanut paste added to all formulations. The use of acacia gum as a binder increased the bars' cohesiveness. Increasing the ratio of cowpea flour to corn flour decreased the cohesiveness and increased protein, fiber, calcium, iron, and folate levels of the bars. Increasing the percentage of baobab pulp powder increased the hardness, fiber, and vitamin C levels, and decreased cohesiveness and water activity of the bars. The bar formulation optimized for sensory acceptance had a cowpea to corn ratio of 85.3:14.7, a baobab level of 9.95%, and 13 g of peanut paste. According to the research, the optimum formulation gave 38%, 32%, 36%, 50%, 11%, and 83% of the recommended dietary allowance of protein, fiber, calcium, iron, vitamin C, and folate, respectively, per serving for school-age children and featured culturally acceptable texture and desirable water activity for commercialization. This study provided critical foundations for the subsequent feasibility assessment of a commercial launch, projected to significantly increase the revenue and nutrient intake of the partnering communities. PRACTICAL APPLICATION: The commercialization of the peanut nutrition bar will serve as a source of new income for Senegalese smallholder women farmers, provide essential nutrients for school-age children and potentially reduce post-harvest loss. Response surface methodology used in this study can also be applied to food product development with indigenous communities to develop an accepted and community-feasible product formulation.

Decomposing consumer and producer effects on sugar from beverage purchases after a sugar-based tax on beverages in South Africa

Growing global concern about obesity and diet-related non-communicable diseases has raised interest in fiscal policy as a tool to reduce this disease burden and its social costs, especially excise taxes on sugar-sweetened beverages (SSBs). Of particular interest have been nutrient-based taxes to improve diet quality. These can incentivize producers to reformulate existing products and introduce healthier alternatives into their ranges. In 2018, South Africa adopted a sugar-based tax on SSBs, the Health Promotion Levy (HPL). Early findings suggest that purchases of higher-sugar taxable beverages fell and purchases of no- and lower-sugar beverages increased, alongside significant reductions in the sugar content of overall beverage purchases. However, underlying these changes are consumption shifts as well as product reformulation and changes in producers' product portfolios. Drawing on a household scanner dataset, this study employed a descriptive approach to decompose changes in the sugar content of households' non-alcoholic beverage purchases into producer factors (reformulation and product entry and exit) and consumer factors (product switching and volume changes as a result of price changes, changing preferences, or other factors). We look at these factors as the tax was announced and implemented across a sample of over 3000 South African households, and then by Living Standard Measures (LSM) groups (middle vs. high). The sugar content of beverage purchases fell by 4.9 g/capita/day overall, a 32% decrease. Taken in isolation, consumer switching and volume changes together led to a reduction equivalent to 71% of the total change, while reformulation accounted for a decrease equal to 34% of that change. Middle-LSM households experienced larger reductions than high-LSM households due to larger changes on the consumer side. For both LSM groups, reformulation-led reductions mostly occurred after implementation, and most changes came from taxable beverage purchases. As sugary drink tax designs evolve with broader implementation globally, understanding both supply- and demand-side factors will help to better assess the population and equity potential of these policies.

The nutrition transition to a stage of high obesity and noncommunicable disease prevalence dominated by ultra-processed foods is not inevitable

The Nutrition Transition model is presented with the nature and pace of change in key stages varying by location and subpopulations. At present, all high-income and many low- and middle-income countries are in a stage of the transition where nutrition-related noncommunicable diseases including obesity, type 2 diabetes, and hypertension are dominating adult morbidity and mortality and are very high or growing rapidly in prevalence. Some countries still have key subpopulations facing hunger and undernutrition defined by stunting or extreme thinness among adults. We call these double burden of malnutrition countries. All low- and middle-income countries face rapid growth in consumption of ultra-processed food and beverages, but it is not inevitable that these countries will reach the same high levels of consumption seen in high-income countries, with all the negative impacts of this diet on health. With great political and civil society commitment to adoption of policies shown in other countries to have improved dietary choices and social norms around foods, we can arrest and even reverse the rapid shift to diets dominated by a stage of high ultra-processed food intake and increasing prevalence of nutrition-related noncommunicable diseases.

Beyond price and income: Preferences and food values in peri-urban Viet Nam

Sub-optimal diets are one of the most important risk factors contributing to the global burden of disease. Developing a better understanding of the drivers of food choice, including the role of individual preferences, is important to address this issue. The objective of this mixed methods research was to identify the relative importance of preferences for different food quality attributes (e.g. nutrition, food safety, price and convenience) that might influence shopping habits and food choice in the context of a rapidly changing peri-urban food environment in Hanoi Province, Viet Nam. A total of 264 women were randomly selected and interviewed using Best-Worst Scaling to elicit preferences among food quality attributes for different food groups (leafy green vegetables, fruits, instant foods, snack foods). A subset of these respondents (n = 40) participated in focus group discussions in order to explore their preferences and food values in more detail. The food quality attributes considered to be most important varied by food group with nutrition and food safety (both immediate and future health) ranking highest for leafy green vegetables and fruits, convenience for instant foods, and taste for snack foods. Price was considered least important across all food groups. Focus group discussions reinforced these results with additional insights particularly regarding trade-offs between nutrition, food safety, convenience, and price. This research demonstrates the feasibility of identifying important drivers of consumption in a South East Asian context using Best-Worst Scaling. These results could help inform the design of behavior change interventions and guide food system policies that seek to shift consumer choices towards healthier diets.

Between the City and the Farm: Food Environments in Artisanal Mining Communities in Upper Guinea

Objective:

Artisanal and small-scale mining (ASM) is a widespread livelihood in low- and middle-income countries; however, many in ASM communities face high levels of poverty and malnutrition. The food environments in ASM communities have non-agricultural rural characteristics that differ from those in urban and agricultural rural areas examined in much existing food environment literature.

Design:

We examine these complex external and personal food environments in ASM communities via a study using qualitative and quantitative methods. Market surveys and a cross-sectional household survey, plus qualitative mining site non-participant observations and in-depth structured interviews, were conducted in three waves.

Setting:

Eighteen study sites in ASM communities in northern Guinea.

Participants:

Surveys covered mothers in mining households with young children (n 613); in-depth interviews engaged caregivers of young children (n 45), food vendors (n 40) and young single miners (n 15); observations focused on mothers of young children (n 25).

Results:

The external food environment in these ASM communities combines widespread availability of commercially processed and staple-heavy foods with lower availability and higher prices for more nutritious, non-staple foods. Within the personal food environment, miners are constrained in their food choices by considerable variability in daily cash income and limited time for acquisition and preparation.

Conclusions:

We demonstrate that ASM communities have characteristics of both urban and rural populations and argue for greater nuance and appreciation of complexity in food environment research and resultant policy and programming.

The Processed food revolution in African food systems and the Double Burden of Malnutrition

African consumers have purchased increasing amounts of processed food over the past 50 years. The opportunity cost of time of women and men has increased as more of them work outside the home, driving them to buy processed food and food prepared away from home to save arduous home-processing and preparation labor. In the past several decades, this trend has accelerated with a surge on the supply side of the processing sector and small and medium enterprises (SMEs) and large private companies making massive aggregate investments. Packaged, industrialized, ultra-processed foods and sugar-sweetened beverages (SSBs) are a growing proportion of the processed food consumed. Also, in the past several decades, overweight and obesity have joined the long-standing high levels of stunting and wasting among children and extreme thinness among women of childbearing age. Together these phenomena have formed a double burden of malnutrition (DBM). The DBM has emerged as an important health problem in sub-Saharan Africa. The rise of the DBM and the increase in ultra-processed food consumption are linked. Policy makers face a dilemma. On the one hand, purchases of processed food are driven by long-term factors, such as urbanization, increased income, and employment changes, and thus policy cannot change the pursuit of convenience and labor-saving food. Moreover, much processed food, like packaged milk, is a boon to nutrition, and the processed food system is a major source of jobs for women. On the other hand, the portion (some 10-30%) of processed food that is ultra-processed is a public health challenge, and policy must address its detrimental effects on disease burden. The global experience suggests that double duty actions are most important as are selected policies focused on healthy weaning foods for addressing stunting and taxes on SSBs, nutrition labeling, and other measures can steer consumers away from unhealthy ultra-processed foods to addressing obesity and possibly child nutrition and stunting. We recommend that African governments consider these policy options, but note that the current extreme fragmentation of the processing sector, consisting of vast numbers of informal SMEs in sub-Saharan Africa, and the limited administrative/implementation capacity of many African governments require pursuing this path only gradually.

Micronutrient Fortification of Commercially Available Biscuits Is Predicted to Have Minimal Impact on Prevalence of Inadequate Micronutrient Intakes: Modeling of National Dietary Data From Cameroon

BACKGROUND

Voluntarily fortified snack products are increasingly available but are not necessarily formulated to meet known dietary nutrient gaps, so potential impacts on population micronutrient intake adequacy are uncertain.

OBJECTIVES

We modeled the impacts of hypothetical micronutrient-fortified biscuits on inadequate micronutrient intake in children and women of reproductive age (WRA) in Cameroon.

METHODS

In a nationally representative survey stratified by macro-region (North, South, and Yaoundé/Douala), 24-h dietary recall data were collected from 883 children aged 12-59 mo and from 912 WRA. We estimated usual nutrient intake by the National Cancer Institute method for vitamin A, folate, vitamin B-12, zinc, and iron. We simulated the impact of biscuit fortification on prevalence of micronutrient intake below the estimated average requirement, given observed biscuit consumption, in the presence and absence of large-scale food fortification (LSFF) programs.

RESULTS

Biscuit consumption in the prior 24-h by children and WRA, respectively, ranged from 4.5% and 1.5% in the South, to 20.7% and 5.9% in Yaoundé/Douala. In the absence of LSFF programs, biscuits fortified with retinol (600 μg/100 g), folic acid (300 μg/100 g), and zinc (8 mg/100 g) were predicted to reduce the prevalence of inadequacy among children by 10.3 ± 4.4, 13.2 ± 4.2, and 12.0 ± 6.1 percentage points, respectively, in Yaoundé/Douala. However, when existing vitamin A-fortified oil, and folic acid-fortified and zinc-fortified wheat flour programs were considered, the additional impacts of fortified biscuits were reduced substantially. Micronutrient-fortified biscuits were predicted to have minimal impact on dietary inadequacy in WRA, with or without LSFF programs.

CONCLUSIONS

Given observed patterns of biscuit consumption in Cameroon, biscuit fortification is unlikely to reduce dietary inadequacy of studied micronutrients, except possibly for selected nutrients in children in urban areas in the absence of LSFF programs. As voluntary fortification becomes increasingly common, modeling studies could help guide efforts to ensure that fortified products align with public health goals.
