Behavior Change Interventions to Address Unhealthy Food Consumption: A Scoping Review.

High intakes of sodium, sugar, saturated fats, and trans-fats contributed to 187.7 million disability adjusted life years from noncommunicable diseases globally. Understanding of the global evidence on interventions to reduce consumption of various types of unhealthy food across diverse contexts is needed. We conducted a scoping review to examine the existing evidence on behavior change interventions (BCIs) to address unhealthy food consumption. Through a systematic search of 3 databases conducted in December 2022, 2730 records were retrieved, and 145 studies met the eligibility criteria for review. Only 19% of the studies (n = 28) were from low- and middle-income countries. The key target group for most BCIs was adults ≥20 y (n = 79). Interventions were conducted across 7 types of settings: schools (n = 52), digital (n = 30), community (n = 28), home (n = 14), health facility (n = 12), worksite (n = 6), and market (n = 3). There were 4 mutually inclusive intervention types-information, education, and communication (n = 141); food/beverage substitution (n = 10); interactive games (n = 7); and labeling/warnings at point-of-purchase (n = 3). The study outcomes included consumption of sugar-sweetened beverages (n = 74), packaged salty snacks/fast food (n = 61), sweets (n = 43), and saturated fat (n = 41). Drivers of food choice behaviors, such as knowledge, attitudes, and beliefs; motivation and expectancies; and self-efficacy were reported in 43% of studies. On the basis of reported impact of BCIs on study outcomes, more interventions targeted at adults had positive impacts compared with those targeted at children; intervention packages, including multiple information, education, and communication components also reported impacts more often than single informational interventions. Interpretation of the findings was complicated by the lack of comparability in interventions, evaluation designs, outcome measures of unhealthy food consumption, duration of interventions, and study contexts. Future studies should invest in critical yet underrepresented regions, examine behavioral determinants of unhealthy food consumption and the sustainability of behavior change, and conduct further analysis of effectiveness from experimental studies.

Impact of Suaahara, an integrated nutrition programme, on maternal and child nutrition at scale in Nepal.

Suaahara was an innovative, complex, multi-sectoral, large-scale, nutrition programme in Nepal to increase exposure to nutrition-related information and services, improve nutrition-related knowledge and practices among pregnant women and mothers of infants and young children, and improve their nutrition. This study evaluated the effectiveness of Suaahara to improve nutrition and nutrition-related practices by comparing changes over 10 years between intervention and comparison districts. The samples of households at baseline in 2012 and endline in 2022 were 2040 and 2480, respectively, from 120 old wards. The impact was estimated using intent-to-treat regression models in which survey year, arm and their interaction were fixed effects, accounting for district clustering, with the interaction estimating differences between arms in changes over time. The intervention, relative to comparison, reduced maternal underweight by 8.43 percentage points (p < 0.001), consistent with improved maternal and fetal condition that was manifested as the greater length of 0.761 z-scores (p = 0.004) of infants 0-5.9 months. Complementary feeding practices with children between 6 and 23.9 months of age improved more in the intervention than comparison districts: child dietary diversity by 0.294 food groups (p = 0.072) and minimum dietary diversity by 9.51 percentage points (p = 0.028), feeding sick child more (p = 0.002) and administering oral rehydration solution and zinc for diarrhoea (p = 0.057) by about 17 percentage points each, and minimum meal frequency (p = 0.004) and minimum acceptable diet (p = 0.022) by about 15 percentage points each. Substantial impacts were demonstrated despite political restructuring, earthquakes, and other major challenges that Nepal and Suaahara faced and limitations in statistical power because of the reduced number of districts that then could be included in the study.

Text messages to improve child diets: Formative research findings and protocol of a randomised controlled trial in Nepal.

Given the role of malnutrition in childhood morbidity and mortality, the prioritisation of maternal and child nutrition programmes has grown significantly in the 21st century. Policies and programmes aim to improve infant and young child feeding, but questions persist about the most effective combination of interventions to achieve desired behaviour change. There is increasing interest in mobile-based interventions globally, but scant evidence exists to guide donors, policymakers and programme implementers on their effectiveness. Formative research was conducted to assess the feasibility and acceptance of text message-based interventions and to guide the final design of the text message intervention. This protocol is for a cluster-randomised controlled trial to test the effectiveness of adding text messaging to other ongoing SBC interventions to promote egg consumption, dietary diversity and other ideal dietary practices, particularly among children 12-23 months of age in Kanchanpur, Nepal. The trial findings will contribute to the emerging body of evidence on the effectiveness of using text messages for behaviour change, specifically for young child dietary outcomes in South Asia. Recent studies have suggested that mobile-based interventions alone may be insufficient but valuable when added to other social and behavioural interventions; this trial will help to provide evidence for or against this emerging theory. This trial was registered at ClinicalTrials.gov on 11 March 2019 (ID: NCT03926689) and has been updated twice.

Barriers and facilitators to growth monitoring and promotion in Nepal: Household, health worker and female community health volunteer perceptions.

Growth monitoring and promotion (GMP) is both a service for diagnosing inadequate child growth in its earliest stages and a delivery platform for nutrition counselling. The widespread use of GMP services in developing countries has the potential to substantially reduce persistent child undernutrition through early diagnosis and by linking caregivers and their children to key health and nutrition services. However, researchers have questioned the effectiveness of GMP services, which are frequently undermined by underdeveloped health systems and inconsistent implementation. This analysis examined both supply- and demand-side factors for GMP utility in Nepal from the perspectives of beneficiaries and service providers, particularly focusing on three components of GMP: growth assessment, analysis of growth status and counselling. The most common factors influencing GMP uptake included beneficiaries' perceptions of the relative importance of GMP and the knowledge and skill of frontline workers. Both providers and beneficiaries viewed GMP as a secondary health and nutrition activity and therefore less important than curative services. We found deficits in GMP-related knowledge and skills among providers (i.e. health workers and female community health volunteers), as well as indications of poor training quality and coverage. Furthermore, we found variation in GMP utilization by maternal age, education and residency (alone, nuclear or extended), as well as household socio-economic well-being and rurality. This study is the first to assess factors influencing both beneficiaries and service providers for GMP utilization. Further research is needed to explore the implementation of improved GMP protocols and to evaluate facility-level implementation barriers.

Improving maternal, infant and young child nutrition in Nepal via peer mobilization.

OBJECTIVE: To evaluate the impact of a peer facilitator (PF) approach for improving mothers' knowledge and practices relating to maternal and child nutrition. DESIGN: A quasi-experimental design nested within a large-scale integrated nutrition programme, Suaahara, in Nepal. Suaahara interventions were implemented in all study sites, but peer facilitators were used in only half of the study sites. SETTING: Rural, disadvantaged villages in three districts of Nepal: Bhojpur, Bajhang and Rupandehi. SUBJECTS: Mothers of children aged 6-23·9 months (n 1890). RESULTS: Differences over time between comparison (C) and intervention (I) groups show that the PF approach had a significant positive impact on several indicators of mothers' knowledge and practices relating to maternal and child nutrition: (i) knowing that fruits and vegetables are good for children 6-23·9 months (C: -0·7, I: 10·6; P=0·03); (ii) child dietary diversity (C: 0·02, I: 0·04; P=0·02); (iii) child minimum dietary diversity (≥4 of 7 food groups; (C: 6·9, I: 16·0; P=0·02); (iv) maternal dietary diversity (C: 0·1, I: 0·4; P=0·01); and (v) maternal minimum dietary diversity (≥4 food groups; C: 3·6, I: 14·0; P=0·03). Additionally, exposure to a PF three or more times in the past 6 months was positively associated with a small improvement in maternal (ß=0·06, P=0·04) and child (ß=0·06, P=0·02) dietary diversity scores. Improvements were not observed in maternal health-seeking behaviours such as number of antenatal care visits. CONCLUSIONS: Peer mobilization is a potential approach for improving health- and nutrition-related knowledge and behaviours among women in hard-to-reach communities of Nepal.

Suaahara in Nepal: An at-scale, multi-sectoral nutrition program influences knowledge and practices while enhancing equity.

The burden of undernutrition in South Asia is greater than anywhere else. Policies and programmatic efforts increasingly address health and non-health determinants of undernutrition. In Nepal, one large-scale integrated nutrition program, Suaahara, aimed to reduce undernutrition among women and children in the 1,000-day period, while simultaneously addressing inequities. In this study, we use household-level process evaluation data (N = 480) to assess levels of exposure to program inputs and levels of knowledge and practices related to health, nutrition, and water, sanitation, and hygiene (WASH). We also assess Suaahara's effect on the differences between disadvantaged (DAG) and non-disadvantaged households in exposure, knowledge, and practice indicators. All regression models were adjusted for potential confounders at the child-, maternal-, and household levels, as well as clustering. We found a higher prevalence of almost all exposure and knowledge indicators and some practice indicators in Suaahara areas versus comparison areas. A higher proportion of DAG households in Suaahara areas reported exposure, were knowledgeable, and practiced optimal behaviors related to nearly all maternal and child health, nutrition, and WASH indicators than DAG households in non-Suaahara areas and sometimes even than non-DAG households in Suaahara areas. Moreover, differences in some of these indicators between DAG and non-DAG households were significantly smaller in Suaahara areas than in comparison areas. These results indicate that large-scale integrated interventions can influence nutrition-related knowledge and practices, while simultaneously reducing inequities.
