Food Systems Interventions for Nutrition: Lessons from 6 Program Evaluations in Africa and South Asia.

Although there is growing global momentum behind food systems strategies to improve planetary and human health-including nutrition-there is limited evidence of what types of food systems interventions work. Evaluating these types of interventions is challenging due to their complex and dynamic nature and lack of fit with standard evaluation methods. In this article, we draw on a portfolio of 6 evaluations of food systems interventions in Africa and South Asia that were intended to improve nutrition. We identify key methodological challenges and formulate recommendations to improve the quality of such studies. We highlight 5 challenges: a lack of evidence base to justify the intervention, the dynamic and multifaceted nature of the interventions, addressing attribution, collecting or accessing accurate and timely data, and defining and measuring appropriate outcomes. In addition to more specific guidance, we identify 6 cross-cutting recommendations, including a need to use multiple and diverse methods and flexible designs. We also note that these evaluation challenges present opportunities to develop new methods and highlight several specific needs in this space.

Behaviour change communication for child feeding in social assistance: A scoping review and expert consultation.

To increase the effectiveness of social assistance on child nutrition, programmes are increasingly combined with behaviour change communication for improved infant and young child feeding (BCC for IYCF). Unfortunately, there is limited knowledge about which BCC strategies are most effective when combined with social assistance. A systematic scoping review and an expert consultation was conducted to (1) describe the landscape of BCC for IYCF strategies used in social assistance within low- and middle-income countries and (2) to examine the effects of these BCC strategies on IYCF practices and child nutrition. Ten quantitative, three qualitative and four mixed methods studies were reviewed and complemented by 12 expert consultations carried out between August and October 2020. In most of the studies attendance in BCC for IYCF was conditional for receiving social assistance, although experts agreed that this conditionality may be counterproductive. A variety of BCC strategies were used with two being most common-group sessions with pre-determined topics and individual counselling. Context-specific adaptation, interactive delivery and building on existing IYCF knowledge emerged as crucial but was perceived as economically infeasible in social assistance programmes. Given the variety of BCC strategies and inconsistency in outcomes, it is impossible to draw conclusions regarding effectiveness. Nevertheless, tentative evidence suggests that the promotion of existing nutrition services, educational group sessions and individual counselling may be effective in improving IYCF. BCC for IYCF can make social assistance more beneficial, but may increase costs, demands on beneficiaries, and deviate from the original focus of the programmes.

How do couples influence each other's physical activity behaviours in retirement? An exploratory qualitative study.

BACKGROUND: Physical activity patterns have been shown to change significantly across the transition to retirement. As most older adults approach retirement as part of a couple, a better understanding of how spousal pairs influence each other's physical activity behaviour in retirement may help inform more effective interventions to promote physical activity in older age. This qualitative study aimed to explore and describe how couples influence each other's physical activity behaviour in retirement. METHODS: A qualitative descriptive study that used purposive sampling to recruit seven spousal pairs with at least one partner of each pair recruited from the existing EPIC-Norfolk study cohort in the east of England, aged between 63 and 70 years and recently retired (within 2-6 years). Semi-structured interviews with couples were performed, audio-recorded, transcribed verbatim and analysed using data-driven content analysis. RESULTS: Three themes emerged: spousal attitude towards physical activity, spouses' physical activity behaviour and spousal support. While spouses' attitudes towards an active retirement were concordant, attitudes towards regular exercise diverged, were acquired across the life course and were not altered in the transition to retirement. Shared participation in physical activity was rare and regular exercise was largely an individual and independent habit. Spousal support was perceived as important for initiation and maintenance of regular exercise. CONCLUSIONS: Interventions should aim to create supportive spousal environments for physical activity in which spouses encourage each other to pursue their preferred forms of physical activity; should address gender-specific needs and preferences, such as chances for socialising and relaxation for women and opportunities for personal challenges for men; and rather than solely focusing on promoting structured exercise, should also encourage everyday physical activity such as walking for transport.

The experience of physical activity and the transition to retirement: a systematic review and integrative synthesis of qualitative and quantitative evidence.

BACKGROUND: The transition to retirement has been recognised as a critical turning point for physical activity (PA). In an earlier systematic review of quantitative studies, retirement was found to be associated with an increase in recreational PA but with a decrease in PA among retirees from lower occupational groups. To gain a deeper understanding of the quantitative review findings, qualitative evidence on experiences of and views on PA around the transition to retirement was systematically reviewed and integrated with the quantitative review findings. METHOD: 19 electronic databases were searched and reference lists were checked, citations tracked and journals hand-searched to identify qualitative studies on PA around the transition to retirement, published between January 1980 and August 2010 in any country or language. Independent quality appraisal, data extraction and evidence synthesis were carried out by two reviewers using a stepwise thematic approach. The qualitative findings were integrated with those of the existing quantitative systematic review using a parallel synthesis approach. RESULTS: Five qualitative studies met the inclusion criteria. Three overarching themes emerged from the synthesis of these studies: these related to retirees' broad concepts of PA, the motives for and the challenges to PA in retirement. Integrative synthesis of the qualitative findings with the quantitative evidence offered several potential explanations for why adults might engage in more recreational PA after the transition to retirement. These included expected health benefits, lifelong PA patterns, opportunities for socialising and personal challenges, and the desire for a new routine. A decrease in PA among retirees from lower occupational groups might be explained by a lack of time and a perceived low personal value of recreational PA. CONCLUSIONS: To encourage adoption and maintenance of PA after retirement, interventions should promote health-related and broader benefits of PA. Interventions for retirees from lower occupational groups should take account of busy post-retirement lifestyles and the low personal value that might be attributed to recreational PA. Future research should address predictors of maintenance of recreational PA after the transition to retirement, the broader benefits of PA, and barriers to PA among retirees from lower occupational groups.

Factors influencing the performance of community health workers: A qualitative study of Anganwadi Workers from Bihar, India.

Globally, there remain significant knowledge and evidence gaps around how to support Community Health Worker (CHW) programmes to achieve high coverage and quality of interventions. India's Integrated Child Development Services scheme employs the largest CHW cadre in the world-Anganwadi Workers (AWWs). However, factors influencing the performance of these workers remain under researched. Lessons from it have potential to impact on other large scale global CHW programmes. A qualitative study of AWWs in the Indian state of Bihar was conducted to identify key drivers of performance in 2015. In-depth interviews were conducted with 30 AWWs; data was analysed using both inductive and deductive thematic analysis. The study adapted and contextualised existing frameworks on CHW performance, finding that factors affecting performance occur at the individual, community, programme and organisational levels, including factors not previously identified in the literature. Individual factors include initial financial motives and family support; programme factors include beneficiaries' and AWWs' service preferences and work environment; community factors include caste dynamics and community and seasonal migration; and organisational factors include corruption. The initial motives of the worker (the need to retain a job for family financial needs) and community expectations (for product-oriented services) ensure continued efforts even when her motivation is low. The main constraints to performance remain factors outside of her control, including limited availability of programme resources and challenging relationships shaped by caste dynamics, seasonal migration, and corruption. Programme efforts to improve performance (such as incentives, working conditions and supportive management) need to consider these complex, inter-related multiple determinants of performance. Our findings, including new factors, contribute to the global literature on factors affecting the performance of CHWs and have wide application.

The double burden of malnutrition in SE Asia and the Pacific: priorities, policies and politics.

The double burden of malnutrition is defined by the co-existence of serious levels of under- and overnutrition.(1) Nowhere have overweight rates risen as fast as in the regions of South East Asia and the Pacific. The regions are also burdened with high and often stagnant levels of undernutrition. For countries for which data are available, the regions contain nearly half of the individuals, world wide, suffering from a double burden of malnutrition. This article reviews the trends and their consequences and for nine countries in these two regions it reviews the drivers of the problem and attempts to manage it. The article concludes with an analysis of the political challenges and opportunities presented by the double burden and some suggestions for a leadership agenda within the region to address it.

Understanding the causes and consequences of injuries to adolescents growing up in poverty in Ethiopia, Andhra Pradesh (India), Vietnam and Peru: a mixed method study.

The World Health Organization estimates that almost half of all premature deaths among 15- to 19-year olds can be attributed to injuries with most (95%) fatal injuries occurring in low- and middle-income countries. Yet the evidence base for adolescent injuries in low-income countries is poor. This article uses a mixed method approach to gain an understanding of patterns, causes and consequences of unintentional injuries among adolescents aged between 14 and 16 years in four low-income country settings. Survey data collected in 2009 in Ethiopia, India (Andhra Pradesh), Peru and Vietnam (from ~900 adolescents in each country) were integrated with qualitative research (conducted between 2007 and 2011) with a nested sample of older cohort children in Ethiopia (n = 25) and India (n = 25) using an iterative process. Logistic regression models were fitted to examine potential risk factors for injuries. Injuries were a concern for adolescents in all countries and occurred during work, recreation and sports or transportation. Being male was associated with an increased risk for all types of injuries, whereas being poor was only significantly associated with work injuries. Area of residence (urban vs rural) made a difference in some countries and for some kinds of injuries as did perceived health status. Qualitative findings highlight the consequences of injuries not only for the adolescents but also for the social and economic status of the entire household. Injury prevention programmes need to be specific to cultural and environmental settings, expectations of adolescent's responsibilities and responsive to the context of poverty.

Changes in household, transport and recreational physical activity and television viewing time across the transition to retirement: longitudinal evidence from the EPIC-Norfolk cohort.

BACKGROUND: Retirement is associated with an increase in recreational physical activity but its impact on other domains of activity (at home, for transport) and sedentary behaviour, such as time spent watching television (TV) is unknown. We examined the association between retirement and changes in domain-specific and overall activity and TV viewing. METHODS: Data were derived from the population-based EPIC (European Prospective Investigation into Cancer)-Norfolk cohort. Physical activity and TV viewing time were self-reported at baseline (1997-2000) and follow-up 2 (2006-2007) by 3334 participants employed at baseline, of whom 785 (24%) were retired at follow-up 1 (2002-2006). Multivariable regression models were fitted to estimate the association between retirement and changes in physical activity and weekly TV viewing time. RESULTS: Compared with continued employment, retirement was associated with a decline in overall activity (men: non-manual, -40.9 MET h/wk; manual, -49.6 MET h/wk; women: non-manual, -26.9 MET h/wk; manual, -31.6 MET h/wk; all p<0.001 (MET, metabolic equivalent of task)). Domain-specific activity declined for transport and occupational (p<0.001) and increased for recreational (p<0.02) and household (p≤0.002) activity. We observed significant interaction between retirement and social class in respect of overall and domain-specific activity apart from household activity. Retirement was associated with a mean increase in TV viewing time, with the largest increase among manual social classes (men: +3.9 h/wk; women: +2.8 h/wk; both p<0.001). CONCLUSIONS: Interventions should aim to promote household and transport as well as recreational activity. Further research on the impact of retirement on sedentary behaviour is needed.

Cohort profile: the Young Lives study.

Young Lives is an international longitudinal study investigating the changing nature of childhood poverty in four low-income countries [Ethiopia, India (Andhra Pradesh), Peru and Vietnam] over a 15-year period. In each country, the cohort is comprised of ≈ 2000 children aged between 6 and 18 months and up to 1000 children aged between 7 and 8 years, recruited in 2002 and sampled from 20 sentinel sites. The first survey data collection from primary caregivers and older children took place in 2002, the second in 2006-07 and the third in 2009-10. Data on the community contexts were collected to complement the household surveys. To elaborate and extend the quantitative data, longitudinal qualitative research with a subgroup of the children was carried out in 2007, 2008 and 2010-11. Topic areas covered included nutrition, health and well-being, cognitive and physical development, health behaviours and education, as well as the social, demographic and economic status of the household. Survey data from the study are archived in the International Section of the UK Public Data Archive.

Physical activity and transitioning to retirement: a systematic review.

CONTEXT: The transition to retirement has been recognized as a turning point in determining physical activity and may present a critical "window" for promoting physical activity. This systematic review examined changes in physical activity across the retirement transition, whether these changes vary by SES, and what is known about predictors of these changes. EVIDENCE ACQUISITION: Peer-reviewed articles and gray research literature, published between January 1980 and July 2010 in any country or language, were identified. Longitudinal and cross-sectional observational studies were included. Study selection, quality assessment, data extraction, and synthesis were performed between July 2010 and March 2011. A harvest plot approach to visualizing the findings was combined with a narrative synthesis. EVIDENCE SYNTHESIS: Of the 19 included studies, 11 examined changes in exercise, or leisure-time physical activity, or both; seven, changes in total physical activity; and one study, both. Most studies used single-item measures of physical activity (n=9) or custom questionnaires (n=6). Results suggested that exercise and leisure-time physical activity increased after the retirement transition, whereas findings regarding total physical activity were inconsistent. SES moderated the association, with low SES being associated with a decrease and high SES with an increase in physical activity. Evidence on predictors of change was scarce and methodologically weak. CONCLUSIONS: Evidence suggests that exercise and leisure-time physical activity increases after the retirement transition, but whether and how total physical activity changes is unclear. Imprecise physical activity measures used in primary studies limit conclusions, and this highlights the need for further research.
