Socio-Economic Inequalities in the Double Burden of Malnutrition among under-Five Children: Evidence from 10 Selected Sub-Saharan African Countries

The double burden of malnutrition in individuals: Identifying key challenges and re-thinking research focus

The 'double burden of malnutrition' is a global health challenge that increasingly affects populations in both low- and middle-income countries (LMICs). This phenomenon refers to the coexistence of undernutrition and overweight or obesity, as well as other diet-related non-communicable diseases, in the same population, household or even individual. While noteworthy progress has been made in reducing undernutrition in some parts of the world, in many of these areas, the prevalence of overweight and obesity is increasing, particularly in urban areas, resulting in greater numbers of people who were undernourished in childhood and have overweight or obesity in adulthood. This creates a complex and challenging situation for research experts and policymakers who must simultaneously address the public health burdens of undernutrition and overweight/obesity. This review identifies key challenges and limitations in the current research on the double burden of malnutrition in individuals, including the need for a more comprehensive and nuanced understanding of the drivers of malnutrition, the importance of context-specific interventions and the need for greater attention to the food environment and food systems. We advocate for the re-evaluation of research strategies and focus, with a greater emphasis on multidisciplinary and systems approaches and greater attention to the synergistic relationship between the biological, environmental, commercial and socio-economic determinants of malnutrition. Addressing these key challenges can enable us to better comprehend and tackle the multifaceted and dynamic issues of the double burden of malnutrition, particularly in individuals and work towards more effective and sustainable solutions.

Efficacy of ready-to-use food supplement for treatment of moderate acute malnutrition among children aged 6 to 59 months

Moderate acute malnutrition (MAM) is a persistent public health problem in Tanzania. The current approach for its management is nutrition counselling. However, there has been no commercial production of ready-to-use supplementary foods for the management of MAM in the country but rather imported from companies outside the country. The objective of the study was to determine the ability of a ready-to-use food supplementation versus corn soya blend (CSB+) to manage MAM. The randomised controlled trial employed three parallel arm approach. The first arm received CSB+ and infant and young child feeding (IYCF) counselling, the second arm received ready-to-use food (RUF) and IYCF counselling and the third arm, a control group, received IYCF as standard care for three consecutive months. Results indicated that the overall proportion of children who recovered from MAM was 65.6%. There was a significant difference (p < 0.001) in the proportion of children who recovered from MAM between the three arms (CSB+, RUF and standard care). Results revealed further a high recovery rate of 83.7% in the RUF arm, followed by 71.9% in the CSB+ arm and 41% in the standard care arm. The risk differences for RUF compared with CSB+ and standard care were 11.8% and 42.7%, respectively. RUFs can be used as an alternative supplement to conventional CSB+ for the management of MAM in children and, thus, has the potential to scale up its use to address the problem of MAM among 6 to 59 months' children.

Double burden of malnutrition among women in reproductive Age (15-49 years) in Sierra Leone: a secondary data analysis of the demographic health survey 2019 (SLDHS-2019)

BACKGROUND

The double burden of malnutrition (DBM) is rising globally, particularly in sub-Saharan Africa. In Sierra Leone, the incidence of overweight, obesity (OWOB), and overnutrition among women has sharply increased. This finding accompanies the high incidence of undernutrition, which has been prevalent for decades. This study aimed to determine the prevalence of different malnutrition categories (underweight, overweight, obesity, and overnutrition) and associated factors among women of reproductive age (15-49 years) in Sierra Leone using secondary data analysis of the Sierra Leone Demographic Health Survey of 2019 (SLDHS-2019).

METHODS

We conducted secondary data analysis of the SLDHS-2019 of 7,514 women aged 15-49 years. We excluded pregnant, post-natal, lactating, and post-menopausal women. Data was collected using validated questionnaires, and respondents were selected through a multistage stratified sampling approach. A multivariable logistic regression analysis was used to determine factors associated with malnutrition among 15-49-year-old women in Sierra Leone.

RESULTS

Among 15-49-year-old women in Sierra Leone, the prevalence of underweight was 6.7% (95%CI: 4.5-8.9%); overweight at 19.7% (95%CI: 17.7-21.7%); obesity was 7.4% (95% CI: 5.2-9.6%); and overnutrition, 27.1% (95%CI: 25.2-29.0%). Women aged 25-34 years were more likely to be underweight (adjusted Odds Ratios, aOR = 1.670, 95%CI: 1.254-2.224; p < 0.001) than those aged 15-24 years; women who were not married were less likely to be underweight (aOR = 0.594, 95%CI: 0.467-0.755; p < 0.001) than married women. Women from the North were less likely to be underweight (aOR = 0.734, 95%CI: 0.559-0.963; p = 0.026) than the East, and those who did not listen to the radio were less likely to be underweight (aOR = 0.673; 95%CI: 0.549-0.826; p < 0.001) than those who did. Overweight was less likely among 25-34 years (aOR = 0.609, 95%CI: 0.514-0.722; p < 0.001) and 35-49 years (aOR = 0.480, 95%CI: 0.403-0.571; p < 0.001) age-groups than 15-24 years; more likely among not married women (aOR = 1.470, 95%CI:1.249-1.730; p < 0.001) than married; less likely among working-class (aOR = 0.840, 95%CI: 0.720-0.980; p = 0.026) than not working-class; most likely in women from the North (aOR = 1.325, 95%CI:1.096-1.602; p = 0.004), and less likely among women from the South (aOR = 0.755, 95%CI: 0.631-0.903; p = 0.002) than the East; less likely among women of middle-wealth-index (aOR = 0.656, 95%CI: 0.535-0.804; p < 0.001), richer-wealth-index (aOR = 0.400, 95%CI: 0.309-0.517; p < 0.001), and richest-wealth-index (aOR = 0.317, 95%CI: 0.234-0.431; p < 0.001) than the poorest-wealth-index; and more likely among women who did not listen to radios (aOR = 1.149; 95%CI:1.002-1.317; p = 0.047) than those who did. The predictors of overweight among women 15-49 years are the same as obesity and overnutrition, except overnutrition and obesity were less likely in female-headed households (aOR = 0.717,95%CI: 0.578-0.889; p < 0.001).

CONCLUSION

The prevalence of all categories of malnutrition among women of reproductive age in Sierra Leone is high, affirming a double burden of malnutrition in this study population. Underweight was more likely among the 25-34-year age group than 15-24-year. The predictors of overweight, obesity, and overnutrition were being unmarried/single, residing in the North, and not listening to the radio. There is an urgent need for policymakers in Sierra Leone to design comprehensive educational programs for women of reproductive age on healthy lifestyles and the dangers of being underweight or over-nourished.
