Behaviour change communication to improve complementary feeding practices in Ethiopia: Couples' beliefs concerning paternal involvement in childcare.

An important cause of stunting is limited consumption of complementary foods, in terms of both quantities and nutrients. Although existing studies show a positive association between fathers' engagement and children's diet, programmes designed to improve complementary feeding practices often only target mothers. In response to this, maternal behaviour change communication (BCC), paternal BCC and food voucher programmes were designed and implemented in Ethiopia using a clustered randomized controlled trial design. The paternal BCC programme included gender-equal messages to increase fathers' participation in childcare, household labour and decision making. The research reported in this paper is an examination of the BCC programmes, characterizing the behavioural, normative and control beliefs of both mothers and fathers in BCC households compared to those in control households. In this study, a total of 40 participants were included, with 13 mother-father pairs in the BCC + food voucher group, and seven pairs in the control group. Each participant was interviewed separately. We found that BCC mothers showed more gender-equal tendencies than the control mothers despite being more rural in location. By contrast, the beliefs of BCC and control fathers were similar overall, suggesting men are more resistant to gender-equal BCC. More work is needed to develop and test effective methods for changing fathers' beliefs and practices.

Implementation research: new imperatives and opportunities in global health.

Implementation research is important in global health because it addresses the challenges of the know-do gap in real-world settings and the practicalities of achieving national and global health goals. Implementation research is an integrated concept that links research and practice to accelerate the development and delivery of public health approaches. Implementation research involves the creation and application of knowledge to improve the implementation of health policies, programmes, and practices. This type of research uses multiple disciplines and methods and emphasises partnerships between community members, implementers, researchers, and policy makers. Implementation research focuses on practical approaches to improve implementation and to enhance equity, efficiency, scale-up, and sustainability, and ultimately to improve people's health. There is growing interest in the principles of implementation research and a range of perspectives on its purposes and appropriate methods. However, limited efforts have been made to systematically document and review learning from the practice of implementation research across different countries and technical areas. Drawing on an expert review process, this Health Policy paper presents purposively selected case studies to illustrate the essential characteristics of implementation research and its application in low-income and middle-income countries. The case studies are organised into four categories related to the purposes of using implementation research, including improving people's health, informing policy design and implementation, strengthening health service delivery, and empowering communities and beneficiaries. Each of the case studies addresses implementation problems, involves partnerships to co-create solutions, uses tacit knowledge and research, and is based on a shared commitment towards improving health outcomes. The case studies reveal the complex adaptive nature of health systems, emphasise the importance of understanding context, and highlight the role of multidisciplinary, rigorous, and adaptive processes that allow for course correction to ensure interventions have an impact. This Health Policy paper is part of a call to action to increase the use of implementation research in global health, build the field of implementation research inclusive of research utilisation efforts, and accelerate efforts to bridge the gap between research, policy, and practice to improve health outcomes.

Strengthening advocacy and policy change for infant and young child feeding.

The creation of environments that are more supportive of optimal infant and young child feeding (IYCF) requires countries to enact policies, such as those related to the Maternity Protection Convention, the International Code of Marketing of Breast-milk Substitutes (the Code), and the Baby-Friendly Hospital Initiative. However, challenges are experienced in the translation of international policy standards into national legal measures, and there is an important gap in understanding how countries achieve progress. Policy advocacy is a nearly universal feature, but there are methodological challenges and few studies evaluating strategies and effects. The purpose of this supplement to Maternal & Child Nutrition is to address those gaps. This supplement contains three papers that present findings from a real-time evaluation of the advocacy efforts of Alive & Thrive (A&T), United Nations International Children's Emergency Fund (UNICEF), and partners, that sought to support governments in fostering enabling environment for optimal IYCF in Southeast Asia (SEA) and Africa. A combination of two emergent, theory-based evaluation approaches was used: developmental evaluation and contribution analysis. The overall objective of the evaluation was to document the extent to which policy objectives were or were not achieved in each country and to identify the key drivers of policy change. One contribution of the supplement is a distinction between and illustration of triggers and drivers of policy change. Three main drivers of policy change were identified: (a) the use of an explicit advocacy approach; (b) the creation of a strategic group of actors; and (c) the realization of 15 critical tasks (more specifically for the Code). Each of the critical tasks has been identified as having triggered progress on the Code in those countries. This supplement provides evidence that the advocacy efforts of A&T, UNICEF, and partners contributed to enhanced IYCF policies in SEA and reveals how it helped to achieve progress. The insights contained in this supplement can serve as a guide for policy advocates for enhanced IYCF policies. A short communication puts findings into perspective within global context.

Translating the International Code of Marketing of Breast-milk Substitutes into national measures in nine countries.

The International Code of Marketing of Breast-milk Substitutes (the Code) adopted by the World Health Assembly (WHA) in 1981 and regularly updated through subsequent WHA resolutions, represents the international policy framework for protecting breastfeeding against inappropriate marketing practices. By March 2016, at least 135 countries had some measures covering provisions of the Code in their legislation. The translation of the International Code into national measures was investigated in the context of the advocacy efforts undertaken by the Alive & Thrive (A&T) initiative with UNICEF and partners. A real-time evaluation was carried out over 22 months in seven Southeast Asian countries (Cambodia, Indonesia, Lao People's Democratic Republic [Lao PDR], Myanmar, Thailand, Vietnam, and Timor-Leste) and two African countries (Burkina Faso and Ethiopia). Drivers of policy change and progress were examined. Two theory-based approaches were used: developmental evaluation and contribution analysis. Data collection methods included participant observation, key informant meetings, in-depth interviews, reflective practice, and desk review. Overall, countries made significant progress in translating the International Code into national measures and in moving forward throughout the policy cycle. The main driver of policy change was the creation of a strategic group, which engaged key relevant actors and supported the government in the performance of 15 critical tasks, which the analysis reveals is a second driver. Those critical tasks are described in this paper and could help public health advocates to anticipate the stages and challenges of policy change and develop more effective strategies to translate the Code into their legal framework.

Contribution of the Alive & Thrive-UNICEF advocacy efforts to improve infant and young child feeding policies in Southeast Asia.

Evaluating the impact of advocacy for policy change presents many challenges. Recent advances in the field of evaluation, such as contribution analysis (CA), offer guidance on how to make credible claims regarding such impact. The purposes of this article are (a) to detail the application of CA to assess the contribution of an advocacy initiative to improve infant and young child feeding policies and (b) to present the emergent theory of change and contribution story of how progress was achieved. An evaluation applying developmental evaluation and CA was conducted on the Alive & Thrive (A&T)-UNICEF initiative in seven Southeast Asian countries to document the extent to which policy objectives were achieved and identify key drivers of policy change. A contribution story was developed based on these experiences. The advocacy approach, which involved a four-part process, contributed directly to (a) set the agenda of various actors and (b) create a strategic group; and indirectly to (a) set and maintain the issue on the agenda at all stages of the policy cycle, (b) support the government to carry out a set of critical tasks, and (c) extend commitment. All of this helped to achieve progress towards policy change. External influences were at play. The flexibility of A&T allowed key actors to utilize the positive external influences and address some of the negative ones through developing responsive strategies mitigating their effects. The emerging contribution story supports that A&T-UNICEF initiative contributed to the progress achieved in the participating countries.

Enhancing governance and strengthening advocacy for policy change of large Collective Impact initiatives.

Nutrition issues are increasingly being addressed through global partnerships and multi-sectoral initiatives. Ensuring effective governance of these initiatives is instrumental for achieving large-scale impact. The Collective Impact (CI) approach is an insightful framework that can be used to guide and assess the effectiveness of this governance. Despite the utility and widespread use of this approach, two gaps are identified: a limited understanding of the implications of expansion for an initiative operating under the conditions of CI and a lack of attention to advocacy for policy change in CI initiatives. In this paper, a case study was undertaken in which the CI lens was applied to the advocacy efforts of Alive & Thrive (A&T), UNICEF and partners. The initiative expanded into a regional movement and achieved meaningful policy changes in infant and young child feeding policies in seven countries in Southeast Asia. These efforts are examined in order to address the two gaps identified in the CI approach. The objectives of the paper are (a) to examine the governance of this initiative and the process of expansion from a national to a regional, multilayered initiative, with attention to challenges, adaptations, and key elements, and (b) to compare advocacy in the A&T-UNICEF initiative and in typical CI initiatives and gain insight into how the practice of advocacy for policy change can be strengthened in CI initiatives.

Boundary-spanning actors in complex adaptive governance systems: The case of multisectoral nutrition.

A growing literature highlights complexity of policy implementation and governance in global health and argues that the processes and outcomes of policies could be improved by explicitly taking this complexity into account. Yet there is a paucity of studies exploring how this can be achieved in everyday practice. This study documents the strategies, tactics, and challenges of boundary-spanning actors working in 4 Sub-Saharan Africa countries who supported the implementation of multisectoral nutrition as part of the African Nutrition Security Partnership in Burkina Faso, Mali, Ethiopia, and Uganda. Three action researchers were posted to these countries during the final 2 years of the project to help the government and its partners implement multisectoral nutrition and document the lessons. Prospective data were collected through participant observation, end-line semistructured interviews, and document analysis. All 4 countries made significant progress despite a wide range of challenges at the individual, organizational, and system levels. The boundary-spanning actors and their collaborators deployed a wide range of strategies but faced significant challenges in playing these unconventional roles. The study concludes that, under the right conditions, intentional boundary spanning can be a feasible and acceptable practice within a multisectoral, complex adaptive system in low- and middle-income countries.

Feasibility of integrating calcium and iron-folate supplementation to prevent preeclampsia and anemia in pregnancy in primary healthcare facilities in Kenya.

Calcium (Ca) supplementation to prevent preeclampsia can save maternal and newborn lives, but there are no program models for integration into existing antenatal care platforms. We used a program impact pathway model to guide the design of integrated Ca and iron-folate (IFA) supplementation in Kenya. We provided healthcare providers with job aids (posters and counseling cards), trained them on counseling techniques and supplementation guidelines, and developed behavior change materials for pregnant women (pill-taking calendars). We allocated health facilities to prescribe either 1.0 or 1.5 g/day Ca, with standard IFA. We collected implementation data from 16 facilities and 990 women. We also explored effects of supplementation on percentage of the population meeting recommended daily allowance. Supplements and job aids were available during 90% of facility spot-check episodes; calendar availability was lower (78%). Over 98% of clients received Ca and IFA supplements, but only 76% received enough Ca supplements to last between antenatal care visits. Among clients that still had pills by return date, adherence was 77% and 83% for the IFA and Ca regimen, respectively. When 1.5 g/day of Ca supplements were prescribed, over 75% of participants met recommended daily allowance. Only 54% met the recommended daily allowance when 1.0 g was prescribed. This study illustrates a systematic approach for integrating Ca supplementation into primary healthcare and demonstrates that such integration is feasible when contextual bottlenecks are addressed. Policy makers and program planners should pay attention to supply chain, healthcare worker dispensing behavior, and appropriateness of regimen for their settings.

Who knows what: An exploration of the infant feeding message environment and intracultural differences in Port-au-Prince, Haiti.

Worldwide, mothers with young children receive many messages about infant feeding. Some messages are generated by health providers and others by the households, communities, and social contexts in which women live. We aimed to determine the scope of infant feeding messages in urban Haiti and to examine intracultural differences in salience of these messages and their alignment with international guidelines. We applied the method of free listing with 13 health workers and 15 human immunodeficiency virus (HIV)-infected and 15 HIV-uninfected mothers with infants 0-6 months old at Groupe Haïtien d'Etude du Sarcome de Kaposi et des Infections Opportunistes in Port-au-Prince, Haiti. Participants listed all messages women receive about infant feeding and specifically about HIV and infant feeding. Message salience was determined by frequency of mention and recall order; messages were coded for key themes. For all groups, the World Health Organization infant feeding recommendations were salient, especially those related to exclusive breastfeeding. Messages across all groups focused on infant health outcomes, with less emphasis on maternal outcomes. Cultural beliefs were also elicited and showed higher salience for mothers than health workers, particularly for consequences of poor maternal nutrition. Health workers' free lists were poorly correlated to those of mothers, whereas those of mothers were highly correlated, regardless of HIV status. Inasmuch as many salient messages were culturally generated, and differences existed between mothers and health workers, we conclude that it is important for health workers to acknowledge the broader infant feeding message environment, and discrepancies within that environment, to address successes and failures in the messages reaching mothers, given potential consequences for mothers' breastfeeding behaviours.

A Simplified Regimen Compared with WHO Guidelines Decreases Antenatal Calcium Supplement Intake for Prevention of Preeclampsia in a Cluster-Randomized Noninferiority Trial in Rural Kenya.

Background: To prevent preeclampsia, the WHO recommends antenatal calcium supplementation in populations with inadequate habitual intake. The WHO recommends 1500-2000 mg Ca/d with iron-folic acid (IFA) taken separately, a complex pill-taking regimen. Objective: The objective of this study was to test the hypothesis that simpler regimens with lower daily dosages would lead to higher adherence and similar supplement intake.Methods: In the Micronutrient Initiative Calcium Supplementation study, we compared the mean daily supplement intake associated with 2 dosing regimens with the use of a parallel, cluster-randomized noninferiority trial implemented in 16 primary health care facilities in rural Kenya. The standard regimen was 3 × 500 mg Ca/d in 3 pill-taking events, and the low-dose regimen was 2 × 500 mg Ca/d in 2 pill-taking events; both regimens included a 200 IU cholecalciferol and calcium pill and a separate IFA pill. We enrolled 990 pregnant women between 16 and 30 wk of gestation. The primary outcome was supplemental calcium intake measured by pill counts 4 and 8 wk after recruitment. We carried out intention-to-treat analyses with the use of mixed-effect models, with regimen as the fixed effect and health care facilities as a random effect, by using a noninferiority margin of 125 mg Ca/d.Results: Women in facilities assigned to the standard regimen consumed a mean of 1198 mg Ca/d, whereas those assigned to the low-dose regimen consumed 810 mg Ca/d. The difference in intake was 388 mg Ca/d (95% CI = 341, 434 mg Ca/d), exceeding the prespecified margin of 125 mg Ca/d. The overall adherence rate was 80% and did not differ between study arms.Conclusions: Contrary to our expectation, a simpler, lower-dose regimen led to significantly lower supplement intake than the regimen recommended by the WHO. Further studies are needed to precisely characterize the dose-response relation of calcium supplementation and preeclampsia risk and to examine cost effectiveness of lower and simpler regimens in program settings. This trial was registered at clinicaltrials.gov as NCT02238704.

Do mobile clinics provide high-quality antenatal care? A comparison of care delivery, knowledge outcomes and perception of quality of care between fixed and mobile clinics in central Haiti.

BACKGROUND: Antenatal care (ANC) is an important health service for women in developing countries, with numerous proven benefits. Global coverage of ANC has steadily increased over the past 30 years, in part due to increased community-based outreach. However, commensurate improvements in health outcomes such as reductions in the prevalence of maternal anemia and infants born small-for-gestational age have not been achieved, even with increased coverage, indicating that quality of care may be inadequate. Mobile clinics are one community-based strategy used to further improve coverage of ANC, but their quality of care delivery has rarely been evaluated. METHODS: To determine the quality of care of ANC in central Haiti, we compared adherence to national guidelines between fixed and mobile clinics by performing direct observations of antenatal care consultations and exit interviews with recipients of care using a multi-stage random sampling procedure. Outcome variables were eight components of care, and women's knowledge and perception of care quality. RESULTS: There were significant differences in the predicted proportion or probability of recommended services for four of eight care components, including intake, laboratory examinations, infection control, and supplies, iron folic acid supplements and Tetanus Toxoid vaccine provided to women. These care components were more likely performed in fixed clinics, except for distribution of supplies, iron-folic acid supplements, and Tetanus Toxoid vaccine, more likely provided in mobile clinics. There were no differences between clinic type for the proportion of total physical exam procedures performed, health and communication messages delivered, provider communication or documentation. Women's knowledge about educational topics was poor, but women perceived extremely high quality of care in both clinic models. CONCLUSIONS: Although adherence to guidelines differed by clinic type for half of the care components, both clinics had a low percentage of overall services delivered. Efforts to improve provider performance and quality are therefore needed in both models. Mobile clinics must deliver high-quality ANC to improve health and nutrition outcomes.

Stigma as a barrier to treatment for child acute malnutrition in Marsabit County, Kenya.

Acute malnutrition affects millions of children each year, yet global coverage of life-saving treatment through the community-based management of acute malnutrition (CMAM) is estimated to be below 15%. We investigated the potential role of stigma as a barrier to accessing CMAM. We surveyed caregivers bringing children to rural health facilities in Marsabit County, Kenya, divided into three strata based on the mid-upper arm circumference of the child: normal status (n = 327), moderate acute malnutrition (MAM, n = 241) and severe acute malnutrition (SAM, n = 143). We used multilevel mixed effects logistic regression to estimate the odds of reporting shame as a barrier to accessing health care. We found that the most common barriers to accessing child health care were those known to be universally problematic: women's time and labour constraints. These constituted the top five most frequently reported barriers regardless of child acute malnutrition status. In contrast, the odds of reporting shame as a barrier were 3.64 (confidence interval: 1.66-8.03, P < 0.05) times higher in caregivers of MAM and SAM children relative to those of normal children. We conclude that stigma is an under-recognized barrier to accessing CMAM and may constrain programme coverage. In light of the large gap in coverage of CMAM, there is an urgent need to understand the sources of acute malnutrition-associated stigma and adopt effective means of de-stigmatization.

Food and nutrition policy: a biological anthropologist's experiences from an academic platform.

OBJECTIVES: Biological anthropologists within academia and in other sectors are increasingly engaged in a variety of problem-oriented research and in the design, implementation, or evaluation of policies and programs, domestically and abroad. Such work can have distinctive requirements in terms of disciplinary background, professional orientation, and professional development. This article explores these issues through the author's autobiographical account of a career in food and nutrition policy from within an academic nutrition department. METHODS: The article is guided by an analytical framework that compares eight projects in terms of their mode of knowledge production, academic impact, public impacts, and personal rewards. The projects range from village-based surveys in Samoa and Malawi to food security planning in upstate New York communities, US policies on genetically engineered (GE) foods, and participant-observer research on nutrition policy development in low-income countries. RESULTS AND CONCLUSIONS: The cumulative experience reveals the importance of a commitment to problem-solving, a transdisciplinary orientation, intellectual and methodological dexterity, ongoing engagement with policy actors and openness to emergent research questions, new research settings, and nontraditional funding sources.

The principles and practices of nutrition advocacy: evidence, experience and the way forward for stunting reduction.

Advocacy represents an intervention into complex, dynamic and highly contextual socio-political systems, in which strategies and tactics must be adjusted on a continual basis in light of rapidly changing conditions, reactions from actors and feedback. For this reason, the practice of advocacy is often considered more art than science. However, capacities and practices for advocacy can be strengthened by sharing and analysing experiences in varying contexts, deriving general principles and learning to adapt these principles to new contexts. Nutrition is a particular context for advocacy, but to date, there has been little systematic analysis of experiences. The purpose of this paper is to illustrate and draw lessons from the practice of nutrition advocacy, especially in relation to stunting and complementary feeding, and suggest ways to strengthen capacities and practices in the future. The strategies and tactics, achievements and lessons learnt are described for three case studies: Uganda, Vietnam and Bangladesh. These cases, and experience from elsewhere, demonstrate that concerted, well-planned and well-implemented advocacy can bring significant achievements, even in short period of time. In light of the global and national attention being given to stunting reduction through the SUN (Scaling Up Nutrition) movement and other initiatives, there is now a need for much stronger investments in strategic and operational capacities for advocacy, including the human, organisational and financial resources for the advocacy and strategic communication themselves, as well as for monitoring and evaluation, supportive research and institutional capacity-building.

Under pressure-exploring partner changes, physiological responses and telomere dynamics in northern gannets across varying breeding conditions.

Background: Life history theory predicts trade-offs between reproduction and survival in species like the northern gannet (Morus bassanus). During breeding, demanding foraging conditions lead them to expand their foraging range and diversify their diet, increasing the risk of reproductive failure. Changing partners may enhance breeding success but lead to more physiological costs. Methods: To investigate the physiological costs of reproduction upon partner changes, we measured and compared 21 biomarkers related to telomere dynamics, oxidative stress, inflammation, hematology, nutritional status, and muscle damage. We used a longitudinal approach with gannets (n = 38) over three contrasting years (2017, 2018 and 2019). Results: Our results suggest that annual breeding conditions exert a greater influence on physiological changes than partnership status. Individuals that changed partner experienced greater short-term stress than retained partners. This transient increase in stress was marked by short-term increases in oxidative lipid damage, lower antioxidant capacity, signs of inflammation, and greater weight loss than individuals that retained partners. During favorable conditions, individuals that changed mates had stabilized telomere length, decreased antioxidant capacity, glucose concentration, and muscle damage, along with increased oxygen transport capacity. Conversely, unfavorable breeding conditions led to increased telomere attrition, stabilized antioxidant capacity, decreased inflammation susceptibility, diminished oxygen transport capacity, and increased muscle damage. In the cases where partners were retained, distinct physiological changes were observed depending on the year's conditions, yet the telomere dynamics remained consistent across both partnership status categories. During the favorable year, there was an increase in unsaturated fatty acids and oxygen transport capacity in the blood, coupled with a reduction in inflammation potential and protein catabolism. In contrast, during the unfavorable year in the retained mates, we observed an increase in oxidative DNA damage, antioxidant capacity, weight loss, but a decrease in inflammation susceptibility as observed in changed mates. Discussion: Our study shows that behavioral flexibility such as mate switching can help seabirds cope with the challenges of food scarcity during reproduction, but these coping strategies may have a negative impact on physiological status at the individual level. In addition, the marked reduction in telomere length observed during harsh conditions, coupled with the stabilization of telomere length in favorable conditions, highlights the long-term physiological impact of annual breeding conditions on seabirds. These findings underscore the effect on their potential survival and fitness, emphasizing that the influence of annual breeding conditions is greater than that of partnership status.

Finding common ground: perspectives on community-based childhood obesity prevention.

To support successful and inclusive community organizing for childhood obesity prevention, this research identified stakeholder perspectives on what communities should do to prevent childhood obesity. It employed factor analysis on statement sorts (Q methodology) conducted by 95 people in an upstate New York community. These participants sorted 36 statements about the issue by how much he or she agreed or disagreed with each. Participants were recruited through strategic snowball sampling to sample a variety of perspectives. The four resulting factors, or perspectives, were interpreted in the context of presort demographic surveys and postsort interviews. This research found one stance that fits the environmental perspective common in public health. The other three factors indicate important variations among perspectives centered on individual responsibility, ranging from libertarian to technocratic views. However, overall, results revealed a substantial degree of agreement among the four perspectives, including on providing access to family activities and on making fruits and vegetables more available and affordable, for example, through subsidies. This article points to common ground for community action on childhood obesity prevention, highlights areas likely to generate considerable contention, and shows whose views are not being accounted for in, at least, this community's childhood obesity prevention project.

Times and partners are a-changin': relationships between declining food abundance, breeding success, and divorce in a monogamous seabird species.

Seabirds exhibit considerable adjustment capacity to cope with environmental changes during the breeding season and to maximize lifetime reproductive output. For example, divorce has been proposed to be an adaptive behavioral strategy in social monogamous species, as a response to poor conditions and low breeding success. Here, we studied divorce at the population and individual levels in northern gannets (Morus bassanus, hereafter gannets) nesting on Bonaventure island (Quebec, Canada). At the population level, we used Granger's method for detecting and quantifying temporal causality between time series (from 2009 to 2019) of divorce rate and breeding success of gannets (n = 809) and we evaluated the relationship between breeding success and biomass of their two principal prey (Atlantic mackerel, Scomber scombrus, and Atlantic herring, Clupea harengus). Our results indicated that breeding success is mainly influenced by the spawning-stock biomass of Atlantic mackerel, and a decrease in breeding success is followed by an increase in divorce rate with a 1-year lag. However, the effect of the interaction between breeding success and year on the proportion of individuals that divorced showed significant inter-annual variation. At the individual level, our results support the adaptive strategy hypothesis of divorce. Indeed, gannets that changed partners did so following a reproductive failure, and there was an increase in breeding success 1 year following the divorce. Being central place foragers, opportunities for dispersal and adaptation are often limited for breeding seabirds in a context of low food abundance. We suggest that behavioral flexibility expressed as divorce would be an efficient short-term strategy for maintaining reproductive performance.

Egg-laying increases body temperature to an annual maximum in a wild bird.

Most birds, unlike reptiles, lay eggs successively to form a full clutch. During egg-laying, birds are highly secretive and prone to disturbance and predation. Using multisensor data loggers, we show that average daily body temperature during egg-laying is significantly increased (1 °C) in wild eider ducks (Somateria mollissima). Strikingly, this increase corresponds to the annual maximum body temperature (40.7 °C), representing a severe annual thermogenic challenge. This egg-laying-induced rise in body temperature may prove to be a common feature of wild birds and could be caused by habitat-related thermoregulatory adjustments and hormonal modulation of reproduction. We conclude our findings with new perspectives of the benefits of high body temperature associated with egg-laying of birds and the potential effect of heat stress that may occur with the future advent of heatwaves.

Operationalizing Implementation Science in Nutrition: The Implementation Science Initiative in Kenya and Uganda.

BACKGROUND: Implementation science (IS) has the potential to improve the implementation and impact of policies, programs, and interventions. Most of the training, guidance, and experience has focused on implementation research, which is only 1 part of the broader field of IS. In 2018, the Society for Implementation Science in Nutrition borrowed concepts from IS in health to develop a broader and more integrated conceptual framework, adapted to the particular case of nutrition and with language and concepts more familiar to the nutrition community: it is called the IS in Nutrition (ISN) framework. OBJECTIVE: The purpose of this research was to generate knowledge concerning challenges and strategies in operationalizing the ISN framework in low- and middle-income country (LMIC) settings. METHODS: The ISN framework was operationalized in partnership with country teams in Kenya and Uganda over a 3-y period as part of the Implementation Science Initiative. An action research methodology (developmental evaluation) was used to provide timely feedback to the country teams, facilitate adaptations and adjustments, and generate the data presented in this article concerning challenges and strategies. RESULTS: Operationalization of the ISN framework proceeded by first articulating a set of guiding principles as touchstones for the country teams and further articulating 6 components of an IS system to facilitate development of work streams. Challenges and strategies in implementing these 6 components were then documented. The knowledge gained through this experience led to the development of an IS system operational model to assist the application of IS in other LMIC settings. CONCLUSIONS: Future investments in IS should prioritize a system- and capacity-building approach in order to realize its full potential and become institutionalized at country level. The operational model can guide others to improve the implementation of IS within a broad range of programs.
