Characteristics and impacts ofSystematic review nutritional programmes to address undernutrition of adults living with HIV in sub-Saharan Africa: a systematic review of evidence

ObjectivesAlthough some studies have identified various challenges affecting nutritional programmes to effectively tackle undernutrition among people living with HIV, evidence about the characteristics and impacts of these programmes on weight-related nutritional outcomes varies based on country contexts, specific programme goals and the implementation processes. This systematic review sought to synthesise evidence on the characteristics and impact of nutritional programmes on weight-related nutritional outcomes of people living with HIV in sub-Saharan Africa.DesignSystematic review.Data sourcesWe searched for primary studies published in the following databases: Web of Science, Medline, Scopus, ScienceDirect, ProQuest and Google Scholar, supplemented by checking reference lists of included papers.Eligibility criteriaStudies published from 2005 to 10 July 2020 and reporting on the weight-related nutritional outcomes of undernourished people enrolled in nutritional programmes in HIV care in sub-Saharan Africa were included.Data extraction and synthesisData were extracted using a data extraction proforma. Weight-related nutritional outcomes of people living with HIV before and after enrolment in a nutritional programme were compared and narratively synthesised.ResultsSixteen studies assessing the impact of nutritional programmes in HIV care on weight-related nutritional outcomes were included. Of these, 13 examined nutritional programmes implemented in health facilities and the remaining three were delivered outside of health facilities. Nutritional recovery (defined differently in the studies) ranged from 13.1% to 67.9%. Overall programme failure rate, which included default after enrolment in a nutritional programme or non-response, ranged from 37.6% to 48.0%. More specifically, non-response to a nutritional programme ranged from 21.0% to 67.4% and default from the programme ranged from 19.0% to 70.6%. Key sociodemographic, clinical and nutritional characteristics that affect nutritional recovery, non-response and default were also identified.Conclusions and recommendationsNutritional programmes in HIV care have led to some improvements in weight-related nutritional outcomes among people living with HIV. However, the programmes were characterised by a high magnitude of default and non-response. To improve desired weight-related nutritional outcomes of people living with HIV, a holistic approach that addresses longer-term determinants of undernutrition is needed.PROSPERO registration numberCRD42020196827.

Association between oral nutritional supplementation and clinical and nutritional outcomes in the management of hospital malnutrition

Objective: To evaluate the association between oral nutritional supplementation and clinical and nutritional outcomes in the management of hospital malnutrition. Methods: This is a longitudinal observational study conducted by collecting electronic medical records of patients admitted to a university hospital between 2019 and 2020. Malnourished adult and elderly patients, who have been eating exclusively orally and using a nutritional supplement, were included.Sociodemographic, clinical, biochemical, nutritional risk, nutritional assessment, acceptance of nutritional prescription and characteristics of the nutritional supplement used were analyzed. An α = 5% was considered. Results: Forty patients were evaluated, most of them elderly and male. Among the oral nutritional supplements, the high-calorie and high-protein types were more prevalent, with an offer twice a day, average use of 39 days, and total acceptance of the nutritional prescription by only 30% of the patients. This nutritional intervention resulted in a slight improvement in anthropometric data, with no significant difference. Conclusion: Using the oral nutritional supplement for a longer period and better adherence would possibly present greater nutritional benefits to patients.

Shifts in Sources of Food but Stable Nutritional Outcomes among Children in the Early Months of the COVID-19 Pandemic

Early in the COVID-19 pandemic, the U.S. Department of Agriculture (USDA), State governments, and school districts took unprecedented steps to mitigate the pandemic’s impact on students’ nutrition. To examine the effect of emergency responses on 6-year-old children’s nutritional outcomes, this study analyzed longitudinal data from a national study of children’s feeding practices, the Special Supplemental Nutrition Program for Women, Infants, and Children—Infant and Toddler Feeding Practices Study-2 (WIC ITFPS-2). Findings include no differences in food insecurity prevalence; however, there were shifts in sources of food, with children in the post-COVID-emergency-declaration (post-ED) group consuming more dietary energy from stores and community food programs and less from restaurants and schools than children in the pre-COVID-emergency-declaration (pre-ED) group (p < 0.01 for all comparisons). Examination of within-person mean differences in 2015 Healthy Eating Index scores and nutrient intakes between ages 5 and 6 years revealed few statistically significant differences between the two groups: children in the post-ED group consumed slightly fewer vegetables (p = 0.02) and less sodium (p = 0.01) than their pre-ED peers. Findings suggest emergency efforts to maintain children’s nutrition were largely successful in the early months of the pandemic. Research is needed to understand the mechanisms by which emergency efforts contributed to these findings.

The forgotten agriculture-nutrition link: farm technologies and human energy requirements

In the quest to reduce global under- and malnutrition, which are particularly high among smallholder farmers, agriculture-nutrition linkages are receiving increasing attention. Researchers have analyzed the link between the quantity and diversity of food that farmers produce and nutritional outcomes but paid limited attention to a third agriculture-nutrition link: the link between how food is produced and nutritional outcomes. This neglect persists despite the majority of smallholder farmers relying on hand tools for farming, which implies heavy physical work and, thus, high energy requirements. To address this research gap, this study compares the energy requirements of farm households in rural Zambia that are characterized by three different levels of mechanization: hand tools, animal drought power, and tractors. 1638 days of detailed time-use and nutrition data were collected from 186 male and female adults and boys and girls during different seasons (land preparation, weeding, and harvesting/processing) using an innovative picture-based smartphone app called “Timetracker”. This data served to calculate different proxies for physical activity and energy requirements using “Ainsworth’s Compendium of Physical Activities”. The results suggest that detailed time-use data offers great potentials to study physical activity and energy requirements. The findings show strong linkages between farm technologies, physical activity levels, and energy requirements, suggesting that this agriculture-nutrition link deserves more scientific and political attention to reduce under- and malnutrition among smallholder farmers.
