Effects of empagliflozin on progression of chronic kidney disease: a prespecified secondary analysis from the empa-kidney trial

BACKGROUND

Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial.

METHODS

EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110.

FINDINGS

Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001).

INTERPRETATION

Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor.

Impact of primary kidney disease on the effects of empagliflozin in patients with chronic kidney disease: secondary analyses of the EMPA-KIDNEY trial

BACKGROUND

The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population.

METHODS

EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110.

FINDINGS

Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1).

INTERPRETATION

In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

190 CONNECTED HEALTH SUSTAINING HOME STAY IN DEMENTIA (CHESS): FACTORS ASSOCIATED WITH THE BURDEN EXPERIENCED BY CAREGIVERS OF PEOPLE WITH DEMENTIA

Background

To date, little research has been carried out exploring the burden experienced by informal caregivers of People with Dementia (PwD). We explored factors that influence the burden experienced by caregivers of PwD over 12 months.

Methods

Fifty-two PwD and their informal caregivers were recruited by convenience sampling to the “CHESS” Study. Data were collected at five time points over 12 months between April 2017 and November 2019. Mixed model analyses were used to investigate associations of caregiver burden (measured by the Zarit-Burden Interview; ZBI) with factors in four domains: 1) Psychological Well-Being (PWB; measures of anxiety, depression, and caregiver distress); 2) Social Capital and Resources (SCR; incorporating access to community-based health services, transportation needs, education level, occupation and living situation of the PwD, and employment status of the caregiver); 3) Physical Fitness and Health (PFH; including the Quantitative Timed Up and Go (QTUG), baseline grip strength, indices of frailty, sensory acuity); and Managing Everyday life with Dementia (MED; incorporating measures of cognition, behavioural disturbances, functional ability, and indices of dependence of PwD.

Results

Across all domains, caregiver burden significantly increased over time (p&lt;0.001) and less burden was experienced by caregivers of older PwD (p&lt;0.05). In PWB, higher caregiver depression levels predicted higher levels of caregiver burden (p=0.033). In the SCR domain, caregivers of PwD who were independent in their transport needs experienced lower levels of burden (p=0.002). No other factors within the PFH or MED domains reached significance in predicting caregiver burden.

Conclusion

This longitudinal analysis elucidates potential predictors of caregiver burden and highlights the need for future research to be carried out in this area. In particular, psychological well-being in caregivers was shown to significantly impact on the experience of burden. Interventions to alleviate caregiver burden should be tailored to include support for psychological well-being.

192 CONNECTED HEALTH SUSTAINING HOME STAY IN DEMENTIA (CHESS): 12-MONTH TRAJECTORY OF QUALITY OF LIFE IN PEOPLE WITH DEMENTIA

Background

Research is needed to examine how Quality of Life (QoL) changes as dementia progresses. We explored QoL trajectories over a 12-month period and examined factors that influence QoL in People with Dementia (PwD).

Methods

Fifty-two PwD and their informal caregivers participated in the “CHESS” Study. Data were collected at five time points over 12 months between April 2017 and November 2019. Mixed-model analyses were used to investigate associations of self-rated QoL and caregiver-rated QoL (measured by the DEMQoL and DEMQoL Proxy, respectively) with factors in four domains: 1) Psychological Well-Being (PWB; measures of anxiety and depression); 2) Social Capital and Resources (SCR; incorporating access to community-based health services, education level, occupation and living situation of the PwD, employment status of the caregiver); 3) Physical Fitness and Health (PFH; including the Quantitative Timed Up and Go (QTUG), baseline grip strength, indices of frailty, sensory acuity); and Managing Everyday life with Dementia (MED; incorporating measures of cognition, behavioural disturbances, functional ability, indices of dependence of PwD).

Results

Across all domains, caregivers’ ratings of QoL for PwD decreased over time (p=0.012). In PWB, greater levels of depression (p=0.007) and anxiety in the PwD (p&lt;0.001) predicted lower self-rated QoL, and higher caregiver anxiety levels predicted lower caregiver-rated QoL (p=0.012). In PFH, having a caregiver administer medication (p=0.03) was associated with higher self-rated QoL. Interestingly, caregiver-rated QoL was higher for PwD who took longer to return to sitting during the QTUG (p=0.043). In MED, being independently mobile (p=0.012) predicted higher self-rated QoL. No other factors within the SCR domain reached significance in predicting QoL.

Conclusion

This longitudinal analysis elucidates potential predictors of QoL in PwD. Psychological well-being in PwD and their caregivers was shown to significantly impact on QoL, and so, these factors should be routinely included in future research studies and clinical assessments.

194 CONNECTED HEALTH SUSTAINING HOME STAY IN DEMENTIA (CHESS): SMART HEALTH TECHNOLOGY ACCEPTABILITY BY INFORMAL CAREGIVERS OF PEOPLE WITH DEMENTIA

Background

The prevalence of dementia is increasing worldwide, and innovative strategies are required to meet increasing demands on health services. The Connected HEalth Sustaining home Stay in Dementia (CHESS) Study aimed to provide support to People with Dementia (PwD) and their caregivers in their homes. We aimed to quantitatively assess the acceptance of smart connected health technology by caregivers of PwD through use of standardised questionnaires.

Methods

Fifty-two PwD and their informal caregivers were recruited by convenience sampling to the intervention arm of the CHESS Study. An additional 25 dyads acted as control participants. Questionnaire data were collected following completion of the CHESS study from 27 informal caregivers from the CHESS Technology group and 16 informal caregivers from the Control group. Measures of health technology acceptability included the System Usability Scale (SUS), the eHealth Literacy Scale (eHEALS), the Technology Readiness Index 2.0 (TRI), and the Unified Theory of Acceptance and Use of Technology Scale (UTAUT). Univariate analyses of variance were used to explore differences between groups.

Results

Internal consistency (Cronbach’s alpha) was high for all measures (range 0.68 – 0.96). The SUS score for the technology group was high (M=70.07, SD=17.69), indicating that the CHESS technology had a high level of usability. All participants had a high level of eHealth literacy (M=33.61, SD=10.51). Both groups performed similarly on the TRI and UTAUT, however the control group indicated greater discomfort with health technology and felt less secure in providing their personal information electronically to healthcare professionals than the technology group.

Conclusion

Caregivers across the technology and control groups had high levels of eHealth literacy and found health technology to be generally acceptable. The CHESS technology in particular was rated as highly usable on the SUS by those who used it. These findings offer support for a Connected Health model of care.

193 CONNECTED HEALTH SUSTAINING HOME STAY IN DEMENTIA (CHESS): HEALTH-RELATED QUALITY OF LIFE IN CAREGIVERS OF PEOPLE WITH DEMENTIA

Background

Caregivers of People with Dementia (PwD) can experience high levels of distress, which can negatively affect their physical and psychological well-being. We explored factors that influence Health-Related Quality of Life (HRQoL) of caregivers of PwD over 12 months.

Methods

Fifty-two PwD and their informal caregivers were recruited by convenience sampling to the “CHESS” Study. Data were collected at five time points over 12 months between April 2017 and November 2019. Mixed model analyses were used to investigate associations of caregiver HRQoL (measured by the EuroQol Visual Analogue Scale; EQVAS) with factors in four domains: 1) Psychological Well-Being (PWB; measures of anxiety, depression, and caregiver distress); 2) Social Capital and Resources (SCR; incorporating access to community-based health services, transportation needs, education level, occupation and living situation of the PwD, and employment status of the caregiver); 3) Physical Fitness and Health (PFH; including the Quantitative Timed Up and Go (QTUG), baseline grip strength, indices of frailty, sensory acuity); and Managing Everyday life with Dementia (MED; incorporating measures of cognition, behavioural disturbances, functional ability, and indices of dependence of PwD.

Results

In the PWB domain, greater levels of caregiver depression (p&lt;0.001) and a greater change over time in caregiver distress related to PwD behavioural disturbances (p=0.008) predicted lower caregiver HRQoL. In the PFH domain, HRQoL was lower for caregivers of PwD who were frail (p=0.04) and had severe comorbidities (p=0.037). None of the factors within the SCR or MED domains reached significance.

Conclusion

This longitudinal analysis elucidates potential predictors of HRQoL in caregivers of PwD. In particular, caregiver depression and distress related to behavioural disturbances in PwD were shown to significantly impact on HRQoL ratings. Caregiver interventions should be tailored to include support for psychological well-being.

99 CHILDHOOD PERSPECTIVES OF PARENTAL YOUNG-ONSET DEMENTIA: A QUALITATIVE DATA SYNTHESIS

Background

While it is less common, young onset dementia manifests at a significantly younger age (&lt; 65). Many people with young onset dementia are parents; however, little is known about impact of the condition on children and young adults. A qualitative thematic analysis was conducted to synthesise the literature on the perspectives of children and young adults with a parent living with young onset dementia.

Methods

Electronic databases were searched in order to identify all peer-reviewed literature in relation to the perspectives of children and young adults with a parent living with young onset dementia. A thematic analysis was conducted on the relevant literature.

Results

The electronic database search resulted in 15 full texts articles. Four main themes with related subthemes emerged from the thematic analysis. The four main themes were: changing family dynamics; psychological and physical strain; stigma and coping strategies.

Conclusion

The current synthesis outlines the perspectives of children and young adults with a parent living with young onset dementia. There is a significant lack of research in this area which adds to the stereotypical view of dementia as an older person’s disease. This can lead to children and young adults being impacted by lack of awareness and stigma resulting in significant psychosocial problems. As the number of people living with dementia (including young onset) is set to increase, future research with children and young adults with a parent with young onset dementia is important in order to better support this cohort.

How Schwartz’ Basic Human Values Influence Food Choices in Kenya and Tanzania

Objectives

To identify and describe how values drive food choice of vulnerable consumers in two East African countries, Kenya and Tanzania.

Methods

Secondary data analysis was conducted on focus group discussions from studies in Kenya and Tanzania. A codebook was developed based on Schwartz's theory of basic human values. A priori coding was conducted in NVivo 12 followed by a narrative comparative analysis, which included review by original principal investigators.

Results

Values of conservation (security, conformity, tradition), openness to change (self-directed thought and action, stimulation, indulgence), self-enhancement (achievement, power, face), and self-transcendence (benevolence dependability and caring) were prominent drivers of food choice in both settings. While tradition was an important value in food choice, new social situations and food environments rendered reprioritization, especially pertaining to youth and animal source foods. Openness to change values were readily cited, especially in peri-urban Kenya with many new foods and diverse neighborhoods. Values of independent thought and action were drivers of mothers’ food choices for families. Benevolence security and caring were drivers choices for child feeding and selecting trustworthy food vendors. Many participants described how values existed in tension. For example, changes in livelihood led to a reprioritization of values like stimulation or indulgence over tradition.

Conclusions

Values were important drivers of food choice in both settings, particularly for meat. Future efforts to promote healthy, sustainable diets will require policy and broad consumer support to succeed. Examining the values that drive food choice in different contexts is necessary especially to minimize unintended consequences, controversy, and perhaps opposition in the implementation of policies and programs.

Perspectives about Food Safety in Diverse Low- and Middle-income Countries

Objectives

Concerns about unsafe food influence food choice and consumption of unsafe foods increase morbidity and mortality, particularly in low- and middle-income countries. Addressing unsafe food is dominated by mitigation of biological and chemical hazards through supply-side risk management, with less emphasis on individuals’ experiences and perspectives of food safety. We aimed to identify and categorize perspectives about food safety in five countries.

Methods

Five studies designed to address drivers of food choice in low- and middle-income countries provided transcripts from 17 focus groups discussions and 303 interviews in Kenya, Ghana, India, Guinea, and Vietnam. We analyzed transcripts using a priori and emergent coding techniques that involved a constant comparative method.

Results

Individuals constructed meaning about food safety through personal experience and social influences. Community and family members contributed knowledge about food safety. Concerns about food safety were influenced by reputations of and relationships with vendors. Concerns were amplified by mistrust of vendors’ purposeful adulteration, unsafe selling practices, and new methods to produce food. Individuals were reassured of food safety by positive relationships with vendors; home-cooked meals; implementation of policies and regulations being followed; vendor adherence to environmental sanitation and food hygiene practices; cleanliness of vendors’ appearance; vendors’ or producers’ agency to use risk mitigation strategies; and transparency in production, processing, and distribution of food.

Conclusions

Individuals’ perspectives about food safety influence food choice behaviors. The success of food-safety policies hinges on consideration of these perspectives.

Perspective: Food Environment Research Priorities for Africa-Lessons from the Africa Food Environment Research Network

Over the last 2 decades, many African countries have undergone dietary and nutrition transitions fueled by globalization, rapid urbanization, and development. These changes have altered African food environments and, subsequently, dietary behaviors, including food acquisition and consumption. Dietary patterns associated with the nutrition transition have contributed to Africa's complex burden of malnutrition-obesity and other diet-related noncommunicable diseases (DR-NCDs)-along with persistent food insecurity and undernutrition. Available evidence links unhealthy or obesogenic food environments (including those that market and offer energy-dense, nutrient-poor foods and beverages) with suboptimal diets and associated adverse health outcomes. Elsewhere, governments have responded with policies to improve food environments. However, in Africa, the necessary research and policy action have received insufficient attention. Contextual evidence to motivate, enable, and create supportive food environments in Africa for better population health is urgently needed. In November 2020, the Measurement, Evaluation, Accountability, and Leadership Support for Noncommunicable Diseases Prevention Project (MEALS4NCDs) convened the first Africa Food Environment Research Network Meeting (FERN2020). This 3-d virtual meeting brought researchers from around the world to deliberate on future directions and research priorities related to improving food environments and nutrition across the African continent. The stakeholders shared experiences, best practices, challenges, and opportunities for improving the healthfulness of food environments and related policies in low- and middle-income countries. In this article, we summarize the proceedings and research priorities identified in the meeting to advance the food environment research agenda in Africa, and thus contribute to the promotion of healthier food environments to prevent DR-NCDs, and other forms of malnutrition.

Examining demographic characteristics and food access indicators from the location of vegan soul food restaurants in the south

Objective: There have been a number of soul food restaurants serving exclusively vegan meals opening up across the country to appeal to African Americans and others interested in eating healthier soul foods. This study determined the number of restaurants serving vegan soul foods in the South and identified the locations of these restaurants in order to understand the characteristics of the surrounding communities that they serve.Design: Two reviewers identified restaurants using standardized search criteria for menu items in the 16 states (and the District of Columbia) that are categorized as being in the South from the Census Bureau. Mean percentage of African Americans, poverty rates, and obesity rates by county where restaurants were located were collected via census data. Restaurants were classified as being in or out of a food desert zone using the United States Department of Agriculture's (USDA) food atlas map (0.5- and 1.0-mile radius). T-tests were conducted to test for differences in the census data between the restaurants that were considered to be in and out of a food desert zone.Results: Overall, 45 restaurants met the inclusion criteria. Counties where restaurants were located had a mean African American population of 36.5 ± 18.5%, mean poverty rate of 15.5 ± 3.85% and mean obesity rate of 26.8 ± 4.8%. More than one third (n = 18, 40.0%) of the restaurants were considered to be in a food desert zone. There were no significant differences in the mean population, obesity, and poverty rates between restaurants classified in a food desert zone and restaurants not located in a food desert zone.Conclusion: A significant number of restaurants were classified in food desert zones, implying their potential to provide healthier meals by serving vegan soul foods to residents in the surrounding neighborhoods. Future work should assess how these restaurants might influence healthier eating habits in their communities.

210 A SYSTEMATIC REVIEW OF LONG-TERM OUTCOME COLLECTION FOLLOWING HIP FRACTURE IN IRELAND FROM 2005 TO 2021

Background

The Irish Hip Fracture Database (IHFD) drives clinical improvements across 16 acute hospitals for over 3,500 patients annually. The IHFD aims to begin recording long-term outcomes. Past practice in Ireland could inform this activity. This review aims to identify and summarise studies that have collected long-term outcomes following hip fracture in Ireland.

Methods

A search of electronic databases (MEDLINE, Embase, Scopus, Web of Science, CINAHL) and grey literature was conducted in July 2021 for articles, abstracts, theses and reports. Search terms related to hip fracture and Ireland. Studies published from 2005–2021 were included if post-hospital discharge data were collected in the Republic of Ireland for patients with hip fracture. Study and patient characteristics, data collection methods and long-term outcomes were extracted.

Results

From all sources, 21 articles, 3 theses and 84 abstracts from 18 clinical sites were identified. Numbers of patients with hip fracture ranged from 9 to 2,483 (median 168) across publications. The most common outcome recorded was mortality (59% of publications), most frequently at 30 days and/or one year. Ascertainment methods for mortality included electronic patient records, online death notices, phone calls to family or general practitioners and the national death register. Non-mortality long-term outcomes were assessed in 64% of publications, most commonly through outpatient or virtual clinics or phone calls. They included place of residence, function, mobility and bone-health status at time-points of 30 days, 6 weeks, 3, 4, 6 or 12 months. Only 11 publications followed patients past the 1 year time-point. One third of publications did not report data collection methods.

Conclusion

Meta-analyses of results will provide estimates of mortality rates and other key hip fracture outcomes. Some long-term outcomes have been collected at most hospitals treating acute hip fracture in Ireland in the last 15 years. Qualitative research in needed to identify facilitators of follow-up to inform practice nationally.

Role of Alternative Caregivers in Food Choices for Young Children in Semi-urban and Urban Mexico

Objectives

This work aimed to understand what alternative caregivers value in making food choices for children and the perspectives of alternative caregivers on their role in making food choices to feed children.

Methods

This qualitative study was conducted in low-income semi-urban and urban communities of the State of Mexico, Mexico. Primary caregivers of children aged 12–59 months named people they considered alternative caregivers. A convenience sample was used for the selection of 16 alternative caregivers. Semi-structured interviews were conducted with alternative caregivers. On average interviews lasted 37.2 minutes; interviews were audio-recorded and transcribed verbatim. All Transcriptions were read, coded, and analyzed using a grounded theory approach. NVivo 10 was used for data management and analysis.

Results

Alternative caregivers were related to children as grandmothers (n = 10), fathers (2), aunts (2), uncle (1), and friend (1). Their average age was 52 years. The highest education was technical school and the lowest was no schooling. Most were homemakers. Almost all shared the same house or land with the children. Alternative caregivers chose the foods fed to children based on how nutritious and healthy food was, children, wanting or desiring certain food, their desire of the child to eat well, the affordability of the food, and how appropriate the food was for the age of children. Alternative caregivers described more influence on the process of decisions about food purchase, cooking, and feeding the child when they were closely related to the child and lived in the same household or land. Alternative caregivers who were not as active in all the process of decisions participated with advice to mothers on what to feed the child. When alternative caregivers expressed affection for children, they showed more interest in what children eat.

Conclusions

Alternative caregivers had a substantial role in the process of making food choices for children. Considering how alternative caregivers participate and influence what children eat may be important in efforts to promote healthy food choices for children.

Recommended Actions in Global Nutrition Initiatives That Link Food Environment and Food Choice

Objectives

To understand how actions that link food environment and food choice, recommended by global nutrition initiatives, seek to promote sustainable healthy diets.

Methods

We reviewed recommended actions addressing food environments and food choice by global nutrition initiatives published between 2015 and 2020. Internal debriefing, expert solicitation, and targeted web searches were used to identify 20 documents, with 12 selected for review. Specific action descriptions were used to generate overarching actions present across the documents, were extracted into a matrix, and then were tabulated across overarching actions retaining document affiliation. The content assigned to each overarching action was disaggregated by environmental and individual focus guided by concepts from existing frameworks pertinent to food environments and food choice.

Results

We identified 13 overarching actions from the documents reviewed, ranging from reorienting agricultural priorities for improved nutrition to creating consumer demand for nutritious foods. The documents differed in the extent of detail describing specific actions. Between 3 and 11 documents were represented in each action. Environmental actions focused on building better bridges across the food value chain, regulation, and investment. Regulation ranged from municipal zoning restrictions of food outlets near schools to national and international strengthening of legally binding agreements for nutrient profiling, labeling, and marketing restrictions. Actions addressing individual behavior were fewer and focused on building capacity with special attention to smallholder farmers and women, recognizing their duality as suppliers and consumers, protecting traditional practices, and applied communication strategies to promote healthy diets.

Conclusions

Actions portrayed prioritization of environmental change to achieve healthy diets with some attention to sustainability, but much less detail was presented about what, how, or why individuals may consider changes to their dietary choices. Better linking individuals’ perspective into environmental change may propel the success of active global efforts.

Perspectives of Urban Ghanaian Adolescents on Healthy Eating Habits

Objectives

Adolescents are vulnerable to diet-related health risks as they experience major life changes alongside food environment changes. In Ghana, non-communicable diseases (NCDs) are rising, and there is a need to understand what, how and why adolescents eat the way they do. This study explored perspectives of adolescents about healthy and unhealthy eating and relationships to portion sizes.

Methods

The Measurement, Evaluation, Accountability, and Leadership Support for NCDs (MEALS4NCDs) Project is measuring the nature and extent of unhealthy food marketing to support public sector actions to create healthier food environments for Ghanaian children. In July-August 2020, 48 interviews with students (14–17 years old) in six districts across the Greater Accra Region were conducted in schools. Interviews were done in English, audio recorded, and transcribed verbatim. Transcripts were coded with NVivo12 using a thematic analysis.

Results

All students demonstrated basic nutrition knowledge and conceptualized healthy eating as “not eating too much”, “a balanced diet,” “not eating late,” and “not eating cold foods.” Connections between NCDs and consumption of foods high in fat, sugar, and salt were rarely made. All students consumed items contrary to what was described as a healthy diet. Students expressed food safety as indicative of healthy food, emphasizing food prepared in a “hygienic environment by a hygienic person,” “a hot temperature,” and “covered.” Participants did not understand portion sizes beyond “too much of anything is bad” and most stated contexts where they would consume smaller or larger portion sizes, such as around strangers (less) or unsure of next meal (more). Participants admitted that peer pressure and food advertising claims informed their food choices and showed minimal knowledge of marketing tactics. Students voiced their limited agency in food choice decisions, citing financial and cultural constraints.

Conclusions

Students had some nutrition knowledge but limited agency to apply it in daily food choices. Interventions should include educating students and parents on diet-related NCDs and deceptive marketing tactics that promote unhealthy foods.

The Role of Stakeholder Framing in Nutrition Agenda-Setting to Address the Double Burden of Malnutrition in Tamil Nadu, India

Objectives

Addressing the double burden of malnutrition in many low- and middle-income countries through double duty strategies requires understanding of how stakeholder framing influences nutrition agenda-setting at the subnational level where policies are translated to address local context. We aimed to identify differences in frames of undernutrition and nutrition-related non-communicable diseases (NCDs) in Tamil Nadu, India and to show how the frames reflect stakeholder intention and action regarding nutrition actions.

Methods

Tamil Nadu is experiencing chronic undernutrition and increasing NCDs and has a history of commitment to addressing undernutrition. We conducted in-depth interviews with stakeholders from nutrition-sensitive disciplines using semi-structured questionnaires (n = 28). Stakeholder responses and established policy process frameworks guided interview coding and thematic analysis.

Results

The frames of undernutrition and NCDs comprised five domains: problem identification, risk factors, target populations, roles for stakeholders, and policy and program response. To address undernutrition, stakeholders consistently identified problems, risk factors, and target populations. Roles and responsibilities for stakeholders were defined, resulting in multisectoral strategies. For NCDs, stakeholders inconsistently identified the same domains, resulting in lack of convergence and bottlenecks to implementing double duty actions.

Conclusions

Nutrition-related NCDs have not reached a critical level of priority and coherence among state-level stakeholders regarding problem identification, risk factors, target populations, responsibility, and solutions, preventing political commitment to addressing them through inclusion in the policy agenda, dedicated resources, and convergence of multisectoral efforts. Development and implementation of multisectoral double duty strategies likely to be effective at the subnational level will require stakeholders to address three challenges in agenda-setting: adequate priority given to the problem, coherence of the policy community, and convergence of actions by multisectoral stakeholders.

Understanding Food Insecurity Resilience of Refugee Families in the United States

Objectives

This research investigated the experience of household food insecurity among Syrian refugees resettled in the US using the lens of family resilience. The objectives were to understand how refugee families create resilience to food insecurity in the US, how they construct the meaning of food insecurity as a source of stress in comparison to other stressors, and what are the family's capabilities that have played a role in their efforts to reduce food insecurity.

Methods

This qualitative case study was conducted with 9 Syrian refugee families who lived in the Washington metropolitan area for 8 years or less. An Arabic semi-structured interview guide was developed. A maximum of three separate interviews were conducted in each family, one with each of two adults (usually parents) and one with the child. Demographics, information about their network of family and friends in the US, and the Arab Family Food Security Scale were collected. Arabic data from 17 in-depth interviews were analyzed using the family adaptation and adjustment response model.

Results

All 9 families were using food assistance programs (SNAP and/or WIC), and 3 of them were food insecure at the time of the interviews. Although experiences of food insecurity varied between families and over time, most families reported greater food insecurity immediately after arriving in the US with food security improving as additional resources (e.g., SNAP) were accessed. However, being food insecure was not perceived as a stressor to most families because they had lived a difficult life in the country from which they escaped. Their major stressors were fear of losing their jobs and of being unable to pay their bills and rent. Each family had a unique capability, with their own combination of resources and strategies, for maintaining household income and food availability, but social networks consistently played an important role in families’ efforts to reduce food insecurity.

Conclusions

Food insecurity was not perceived as a major stressor because families experienced a broad range of insecurities including finances, housing, and employment. The social network was one of the most important resources that supported families’ capabilities to improve their food status.

Perspectives on Food Safety and Their Influence on Food Choice in Low- and Middle-Income Countries

Objectives

Current efforts to address food safety through supply-side risk management consider food safety primarily in terms of biological and chemical hazards, ignoring the importance of individuals’ experiences and perspectives. This study aimed to understand how experiences and perspectives of food safety influence food choice in low- and middle-income countries (LMICs).

Methods

The Drivers of Food Choice Competitive Grants Program funded 15 projects that aimed to understand food choice among the poor across 10 LMICs in Sub Saharan Africa and South and South East Asia. Summaries of the role of food safety in decisions about food choice were reviewed with principal investigators from 6 projects with significant findings. We used an iterative process of thematic analysis across all project summaries followed by respondent validation to categorize findings with shared meaning into themes of conditions

and characteristics that either contributed to perceptions of a lack of food safety or to an overall perspective on food safety.

Results

Food was considered to be safe if purchased from vendors who had good food and personal hygiene practices or with whom individuals had positive relationships. Food was also considered to be safe if it was prepared at home. Perceptions of a lack of food safety were increased by fears of adulteration by vendors and contamination in physical environments with poor sanitation or handling practices. Policies and regulations offered increased guarantees of safety but were not always trusted nor convenient, and social networks and the media were important sources of both real and false information about food safety.

Conclusions

Individuals rely on their experiences, attitudes, knowledge, and perceptions in making decisions about what foods to buy, prepare, and consume, and from which sources. Understanding how perspectives of food safety influence food choice can be harnessed to improve food safety and contribute to sustainable healthy diets. Efforts to achieve sustainable healthy diets through behavior change communication or incentives to supply chain actors must acknowledge perspectives on food safety as important drivers of food choice.

Nonpharmacological interventions for respiratory health in Parkinson's disease: A systematic review and meta-analysis

BACKGROUND AND PURPOSE

Respiratory dysfunction in Parkinson's disease (PD) is often an underdiagnosed and untreated impairment associated with the disease. Clinically, a reactive approach to respiratory morbidity is taken, rather than preventative approaches that address underlying impairment/s. This systematic review identifies the current evidence to support nonpharmacological interventions to improve respiratory impairments in individuals with PD.

METHODS

The relevant literature was searched using a customised and systematic strategy. Randomised and nonrandomised control trials of nonpharmacological interventions targeting respiratory outcome measures in PD were included. Outcomes of interest were respiratory morbidity and mortality, respiratory muscle strength, spirometry measures, lung volumes, peak cough flow, and perception of dyspnoea.

RESULTS

Nonpharmacological interventions included: functional training, generalised strength training, respiratory muscle strength training, aerobic exercise, qigong, yoga, breath stacking, incentive spirometry and singing. Methodological quality of included studies varied. Meta-analyses of nonpharmacological interventions demonstrated significant effects for inspiratory muscle strength (mean difference [MD] 19.68; confidence interval [CI] 8.49, 30.87; z = 3.45; p = 0.0006; I²  = 2%), expiratory muscle strength (MD 18.97; CI 7.79, 30.14; z = 3.33; p = 0.0009; I²  = 23%) and peak expiratory flow (MD 72.21; CI 31.19, 113.24; z = 3.45; p = 0.0006; I²  = 0%). Best-evidence synthesis identified level 1 evidence supporting nonpharmacological interventions for improving peak cough flow and perceived dyspnoea. No studies were identified reporting outcomes of respiratory rate, inspiration:expiration ratio or respiratory morbidity or mortality in PD.

CONCLUSIONS

Nonpharmacological interventions improved respiratory muscle strength and peak expiratory flow in PD. Additional trials targeting respiratory dysfunction and longitudinal studies examining the relationship between respiratory dysfunction and morbidity and mortality rates in PD are required.

Decision-making around admission to intensive care in the UK pre-COVID-19: a multicentre ethnographic study

Predicting who will benefit from admission to an intensive care unit is not straightforward and admission processes vary. Our aim was to understand how decisions to admit or not are made. We observed 55 decision-making events in six NHS hospitals. We interviewed 30 referring and 43 intensive care doctors about these events. We describe the nature and context of the decision-making and analysed how doctors make intensive care admission decisions. Such decisions are complex with intrinsic uncertainty, often urgent and made with incomplete information. While doctors aspire to make patient-centred decisions, key challenges include: being overworked with lack of time; limited support from senior staff; and a lack of adequate staffing in other parts of the hospital that may be compromising patient safety. To reduce decision complexity, heuristic rules based on experience are often used to help think through the problem; for example, the patient's functional status or clinical gestalt. The intensive care doctors actively managed relationships with referring doctors; acted as the hospital generalist for acutely ill patients; and brought calm to crisis situations. However, they frequently failed to elicit values and preferences from patients or family members. They were rarely explicit in balancing burdens and benefits of intensive care for patients, so consistency and equity cannot be judged. The use of a framework for intensive care admission decisions that reminds doctors to seek patient or family views and encourages explicit balancing of burdens and benefits could improve decision-making. However, a supportive, adequately resourced context is also needed.

Food-Choice Values of Elementary School Children and Strategies Used to Influence Mothers’ Food Purchasing Decisions

Objectives

This study aimed to understand the values held by elementary school children in constructing food choices and the strategies they used to influence their mothers’ food purchasing decisions.

Methods

Semi-structured qualitative interviews were conducted with 40 elementary school children (aged 6–11 years) and their mothers living in South Carolina. Food choice information was collected only from children and strategies to influence mothers’ food purchases were collected from both children and mothers. The interviews were audio-recorded, transcribed verbatim, and open-coded. Coding matrices were used to compare children's and mothers’ responses on the children's strategies to influence mothers’ food purchasing decisions.

Results

Children most valued taste, texture, and flavor of the food items, followed by perceived benefits, happiness, craving, following family and friends, the items’ healthfulness, preparation, and presentation when they made food choice decisions. Children reported 157 strategies that they used to influence mothers’ purchasing decisions. Mothers had concordance with 80 strategies that children mentioned. In mother-child dyads, more concordance was observed between mothers and sons than between mothers and daughters. The most common and successful strategies from both the children's and mothers’ perspectives were reasoned requests, repeated polite requests, and referencing friends. Other strategies included offers to contribute money or service, teaming up with siblings, writing a shopping list, and grabbing desired items. Mothers perceived that children had a lot of influence on their food purchasing decisions.

Conclusions

Children were aware of the strategies that would get positive reactions from their mothers. Mothers’ acknowledgement of children's influence on their food purchase decisions suggests that children can serve as change agents for improving mothers’ food purchases if children prefer healthy foods. Interventions are needed for mothers to help address children's strategies to influence mothers to purchase unhealthy foods and make healthy foods more appealing to children instead of yielding to children's requests for unhealthy items.

Stakeholder Engagement Strategies for Policy and Programmatic Uptake: Lessons from the Drivers of Food Choice Competitive Grants Program

Objectives

This study drew upon experiences of stakeholder engagement in food choice research to advance knowledge about best practices.

Methods

The Drivers of Food Choice Competitive Grants Program aimed to understand food choice in low- and middle-income-countries. All funded proposals included stakeholder engagement strategies. Data were from document review of proposals and reports and semi-structured interviews with the principal investigators of the 15 projects. Interviews were transcribed and uploaded into NVIVO 12. The lead author analyzed interviews thematically using an a priori code list and led discussion of themes and patterns through peer review with co-authors.

Results

Grantees developed and implemented a range of strategies. “Uni-directional” strategies were researcher-driven and informational, did not seek input from the target stakeholder, and included one-way communication such as emails, newsletters, meetings, press releases, technical briefs, newspaper articles, and public engagement efforts. “Bi-directional” strategies sought collaboration with stakeholders. Examples were workshops which sought feedback on stakeholder identification, research questions, methods, results, and recommendations. Grantees used unidirectional strategies to increase buy-in and generate demand for results, which helped promote the use of evidence for decision-making. Bi-directional strategies were integral to knowledge production. Grantees thought that bi-directional engagement enhanced the immediate applicability of the research. Grantees developed more- and less-intensive strategies that involved both bi-and uni-directional engagement, depending on goals for uptake.

Conclusions

This research sheds light on the role of stakeholder engagement strategies in advancing multisectoral nutrition. The current landscape of research and practice is fast-paced and complex; ensuring relevance of research via diverse stakeholder engagement strategies should remain a priority for researchers and funders. Our findings may aid researchers in constructing strategies that are responsive to diverse research programs and goals within complex multisectoral nutrition landscapes.

Promoting Co-Responsibility in the Household and Self-Care Through an Intervention for Food-Insecure Women with Excess Body Weight in Costa Rica

Objectives

This intervention targeted change in gender norms and behaviors regarding co-responsibility in the household and self-care among food-insecure women with excess weight. The objectives of this study were to determine what and how changes occurred in perceived gender norms, attitudes, intentions, and behaviors of women and their family and community members regarding co-responsibility and self-care.

Methods

We conducted a two-arm, 6-month cluster-randomized controlled trial in Alajuela. This qualitative study included 62 women, 34 family members, and 9 community members in the intensive arm. This arm consisted of activities at the individual (12 two-hour sessions, 3 follow-up monthly sessions, and one closing session), household (one workshop with household and community members, and homework with family participation), and community (two brochures and one workshop) levels. Data used were from observations and content analysis of participant comments during the workshops (n = 83), pre- and post-semi-structured interviews (n = 35), and focus groups with participating women (n = 49).

Results

Women and family members changed attitudes, intentions, gender norms, and behaviors related to co-responsibility and self-care. Concerning co-responsibility, at baseline all women reported doing most of the domestic work. Most women perceived working outside home as favorable, but those with children worried about childcare. At end-line, women reached more equitable distributions of the domestic work. Many women either obtained a job or began a small business at home and found solutions to balance their job with childcare. Women explained that these changes occurred because they had increased psychological empowerment which allowed them to ask for help at home, search for a job, or accept jobs rejected before. Concerning self-care, women and family members changed self-care behaviors and improved relationships because 1) women understood that self-care first allowed them to care for others and 2) women changed first so their family members followed.

Conclusions

The intervention changed attitudes, intentions, gender norms, and behaviors related to co-responsibility and self-care, which supported improved food security and weight in women.

Role of Social Networks in Maternal Food Choice for Children Ages 1 to 5 Years Old in Rural Mexico

Objectives

To understand the role of mothers’ social networks in the food choices that mothers make for their children ages 1 to 5 years old in rural Mexico.

Methods

In-depth interviews were conducted with 46 participants from 3 rural communities between November and December 2016. The interviews inquired about participants’ child-feeding practices, personal and local beliefs about child feeding, and individuals with whom participants discussed food. All interviews were in Spanish, audio-recorded, transcribed verbatim, verified for quality, and analyzed using the constant comparative method.

Results

The networks that participants described in relation to food choice were largely interconnected and embedded within the social space of their communities. These networks were household family, non-household family, community, children's initial school, and health and pantry personnel. Participants described the functions of each network for the feeding of their children. These functions ranged from directly intervening on feeding behavior in the most proximal network, i.e., household family, to providing formal feeding and nutritional guidance in the most peripheral network, i.e., health and pantry personnel. Some networks had unique functions that no other network had, while some functions were shared across networks. Across the networks, professionals, participants’ mothers and mothers-in-law, community senior women, and other women with children emerged as trusted figures whom mothers would turn to for child-feeding advice. Participants were in constant interaction with their social networks and rarely turned to only one advisor. Participants expressed striking a balance between the input received, what they make of it, and eventually weighing their children's responses, resources available, and situations in which interactions occur and food choice is made for children.

Conclusions

Social networks have vital functions in establishing norms for food choices made for children. The multiplicity of child-feeding advisors may be especially important in strategies that seek to promote healthy food choices for children during developmental years to foster healthy eating patterns.

Liquid Chromatographic Method for Determination of Iodine in Milk: Collaborative Study

Nine laboratories participated in an AOAC International/ International Dairy Federation collaborative study on a liquid chromatographic (LC) method for determination of iodine in milk. Liquid milk is passed through a 25 000 MW membrane filter to remove protein and insoluble material. Iodine (in the form of iodide) in the clear filtrate is separated by reversed-phase ion-pair LC and is detected electrochemically. Participants analyzed 2 commercial pasteurized whole milks and 5 nonfat dry milk powders in blind duplicate. Each sample was tested in duplicate on 2 days. Repeatability and reproducibility standard deviations (sr and SR, respectively) and repeatability and reproducibility relative standard deviations (RSDr and RSDR, respectively) for determinations of iodine in whole milk (mean recovery, 86.7%) were as follows: sr, 22 μg/L; SR, 22 μg/L; RSDr, 8.2%; and RSDR, 8.3%. For powdered milk (mean recovery, 91 %), the values were as follows: sr, 0.14 μg/g; SR, 0.22 μg/g; RSDr, 9.0%; and RSDR, 12.7%. The method was adopted first action by AOAC International.

Double Burden of Malnutrition: The Role of Framing in Development of Political Priority in the Context of Rising Diet-related Non-communicable Diseases in Tamil Nadu, India (P22-005-19)

Objectives

In low- and middle-income countries, non-communicable disease (NCD) prevalence is increasing while undernutrition persists, resulting in a double-burden of malnutrition. How policy actors frame malnutrition may shape policy, programming, and investment. In India, where NCDs are rising rapidly and undernutrition persists throughout the country, much of food and health policy is decentralized, but little is known of how the double burden of malnutrition is understood at the state level. This study aimed to identify and compare frames and priorities for nutrition used by relevant policy actors to help understand the narrative emerging around policy solutions for the double burden of malnutrition.

Methods

Key informants in the health, nutrition, and agriculture fields were identified from policy documents and purposive and snowball sampling. In-depth, semi-structured interviews were held with 28 key informants including international policy advocates, government officials, and state-level implementers in Tamil Nadu. Interviews were audio-recorded, transcribed, and coded with Nvivo 12. Major themes were identified using elements from prior published work: actor power, internal frame, issue characteristics, evaluative dimensions of target populations, priorities emphasized, and potential effects of the frame or likely policy result.

Results

Different actors reported differing priorities for the double burden of malnutrition. There was almost universal concern about stunting and anemia in children and women and consensus on sanitation and dietary diversity as causes of undernutrition, but a lack of clarity regarding diet-related NCDs. Respondents were unclear about which populations to target for the double burden, compared to clear targeting of women and children to address undernutrition. They described lack of convergence or clear roles for actors addressing the double burden, unlike for undernutrition.

Conclusions

There is a lack of consensus on the causes, manifestation, and solutions for the double burden of malnutrition within the policy community. Creating a shared narrative is critical for cohesive and efficient programming to address the double burden of malnutrition.

Stressful Life Changes Affect Nutrition-Related Health Outcomes Among US Army Soldiers (P18-070-19)

Objectives

This prospective cohort study aimed to determine if experiencing stressful life changes were associated with an earlier onset of adverse nutrition-related health outcomes among US Army Soldiers. An additional aim was to determine which stressful life changes were most associated with these outcomes and if there were gender differences in the magnitude of the associations.

Methods

Stressful life changes were changes in marital status, combat deployment or returning from deployment, relocation, adding a child, change in rank, change in occupation, or development of a physical limitation to duty. Nutrition-related health outcomes were hyperlipidemia diagnosis, substantial weight gain, or weight-related separation from the Army. Using longitudinal data from the Stanford Military Data Repository representing all active-duty Soldiers who were age 17–62 between 2011 and 2014 (n = 827,126), event history analysis was used to model the association of stressful life changes with nutrition-related outcomes.

Results

Marriage was found to raise the odds of substantial weight gain three months later by 1.24 times (95% CI: 1.16, 1.32) for men and 1.68 times (95% CI: 1.51, 1.89) for women. Developing a physical duty limitation raised the odds of hyperlipidemia two months later by 1.42 times (95% CI: 1.15, 0.75) for men and 1.83 times (95% CI: 1.01, 3.32) for women and the odds of substantial weight gain two months later by 3.16 times (95% CI: 2.89, 3.44) in men and 1.69 times (95% CI: 1.36, 2.08) in women.

Conclusions

Differences in the magnitude of associations show stressful life changes affect male and female Soldiers differently. Identifying times after stressful life changes when the risk of developing an undesirable health outcome is highest offers new possibilities for proactively addressing health. Findings could guide the timing of interventions to mitigate the effects of stress on health in military and civilian populations.

Association of Food and General Parenting Practices with Young Children's Dietary Behaviors and the Role of Child Difficulty in Self-regulation (OR03-05-19)

Objectives

Understand the association of food and general parenting practices with young children's dietary behaviors and the role of child difficulty in self-regulation in this relationship.

Methods

Data were from the Early Childhood Longitudinal Study – Birth Cohort. Parent-child dyads with non-missing outcomes at age 5 (i.e., weekly frequency of intake of sugar-sweetened beverages, sweet foods and desserts, salty snack foods, fruits, and vegetables) were used (n = 3,250 boys and 3,150 girls). Analyses were done separately for boys and girls. Regression models with full information maximum likelihood were used accounting for clusters in Stata. Each outcome was regressed on food parenting variables at age 4 (i.e., rules about foods, and meal routines of eating as a family and at a regular time) and covariates. General parenting variables at age 4 (i.e., parent-child interaction, difficulty sticking with rules, harsh discipline, rules about watching television, and rules about bedtime), child difficulty in self-regulation at age 4, and their interactions were then added sequentially.

Results

Better food parenting practices at age 4 were associated with less frequent intake of unhealthy and more frequent intake of healthy foods and beverages in both boys and girls at age 5, with some differences by gender. General parenting practices at age 4 were associated with dietary behaviors differently for boys and girls. Difficulty in self-regulation at age 4 significantly modified the association between parenting practices and child's dietary behaviors for boys (evening meals at a regular time and intake of sweet foods and desserts) and girls (parent-child interaction and intake of sugar-sweetened beverages; difficulty sticking with rules and intake of sweet foods and desserts; rules about foods and intake of fruits and vegetables; and harsh discipline and intake of fruits).

Conclusions

Better food parenting and general parenting practices at age 4 were associated with children's healthy dietary behaviors at age 5. These associations differed by gender and child difficulty in self-regulation. Interventions to improve children's dietary behaviors should target parents and children to promote positive parenting in food and non-food settings and support children with difficulty in self-regulation.

Satisfying Children's Desire: A Primary Value Driving Parents’ Food Purchasing Decisions for Elementary-school-aged Children in South Carolina (P10-043-19)

Objectives

This study aimed to understand how parents made food purchasing decisions for their elementary-school-aged children and how they adjudicated among different values to make a purchasing decision.

Methods

Semi-structured qualitative interviews were conducted with 40 parents from low-and middle-income families in South Carolina who were primary food shoppers for their elementary-school-aged children and the households. The interviews were audio-recorded, transcribed verbatim, and open-coded. Coding matrices were used to compare parents’ responses on their decision-making process by race/ethnicity and child age.

Results

Parents adjudicated among nine values when they purchased foods and drinks for their elementary-school-aged children. Satisfying children's desire for a food or drink was the primary value parents identified as driving their food purchasing decisions. Parents also valued nutritional quality of the foods, children's acceptance of the foods, convenience of preparation, cost, health needs of the children, and tradition. Parents wanted their children to eat healthy but reported that they might need to compromise with the healthfulness of the foods because of their children's desire for less healthy foods. Although parents perceived that healthy foods, including fresh fruits and vegetables, are expensive, they wanted to accommodate those foods in their shopping list regardless of the cost if their children desired those foods. Strategies that parents applied to make a balance between children's desire, healthfulness of the foods, and price of the foods included purchasing store brand items, seasonal fruits, and items on sale and promotion, as well as setting rules for the children.

Conclusions

Making food purchasing decision for children is complex as children's desire and acceptance of a food are important in parents’ decisions. Despite that parents valued nutritional quality of foods and health needs, they tend to buy less healthy foods to satisfy their children's desire.

Intervention for Women in Costa Rica Who Have Food Insecurity and Excess Body Weight: A Cluster Randomized Trial (P04-017-19)

Objectives

This study aimed to develop, implement, and evaluate an intervention to simultaneously reduce food insecurity and body weight. We hypothesized that, when compared with the non-intensive arm, women in the intensive intervention arm would reduce food insecurity and body weight and improve social support for healthy eating, psychological and economic empowerment, and food and physical activity behaviors.

Methods

We conducted a cluster-randomized controlled trial in the Central Canton of the Province of Alajuela. Randomization was at the level of the catchment area of the first level of health care in Costa Rica. This 6-month study compared two arms. The intensive arm consisted of activities at the individual (12 two-hour sessions, three follow-up monthly sessions, and one closing session), household (one workshop with the participants’ household and community members, and homework with family participation), and community (two brochures and one workshop) levels. The non-intensive arm was comprised of three one-hour sessions about healthy lifestyles.

Results

A total of 171 participants were enrolled (83 in intensive and 88 in non-intensive arm). At 6 months the intensive arm had significantly greater decreases from baseline in food insecurity (P = 0.004), body mass index (P = 0.010), and waist circumference (P = 0.001) compared with the non-intensive arm. The intensive arm also had also significantly greater increases in psychological (P = 0.014) and economic empowerment, including a greater increase in the contribution to household support (P = 0.030) and more women that found a job (P = 0.018), compared with the non-intensive arm. Women in the intervention arm had significantly greater changes from baseline in the expected direction in food consumption of fried foods (P = 0.029), sausages (P = 0.038), sugar drinks (P = 0.032), salads (P = 0.032), and beans (P = 0.004) compared to women in the non-intensive arm. We did not find any significant differences between the arms in social support, exercise, and consumption of fruits, vegetables and fast foods.

Conclusions

This intervention demonstrates that it is possible to simultaneously reduce food insecurity and reduce, rather than exacerbate, excess weight gain.

Role of Interpersonal Relationships in Mothers’ Foods Choice Decisions for Children Ages 1 < 5 Years in Rural Mexico (P10-051-19)

Objectives

To understand how mothers’ interpersonal relationships influence food choice decisions they make to feed children ages 1 to <5 years old in rural Mexico.

Methods

Semi-structured interviews were conducted with 46 mothers from 3 rural communities in Mexico in November and December 2016. Mothers were asked about their daily activities, their own knowledge about child feeding, the social ties from which they obtain information about child feeding, and local normative beliefs about food. Interviews were audio-recorded, transcribed verbatim, and analyzed using the constant comparative method. Thematic coding was used to identify the underlying values and meanings mothers ascribed to foods and the influential figures in their social circle to understand how interpersonal relationships influenced child feeding decisions.

Results

Most mothers had no formal employment and spent their day in activities such as upkeep of home, caring for their children, getting food, preparing meals, looking after their animals, and harvesting. Most mothers lived in multigenerational households or near relatives. Mothers’ knowledge about child feeding had a foundation in practices from their own mothers, being child caregivers to their siblings, employment as child caregivers in urban settings, and having older children. Mothers had prominent figures who influenced their decisions about child feeding. These figures were older women living in the household, other mothers within their social circle, health and social program personnel, children's fathers, and children themselves. Mothers described specific foods and preparations locally acceptable to feed to children, noting that some beliefs and practices might conflict with others. In making decisions about what to feed their children, mothers appraised who their social ties were and their feeding practices. For example, mothers took in information from other mothers based on their perception of whether the child was well-fed, which included child appearance.

Conclusions

Mothers’ interpersonal relationships played an important role in their child feeding decisions. When designing a program to improve food choice, identifying and accounting for mothers’ key social ties regarding child feeding could enhance positive behavior change.

Farming characteristics and self-reported health outcomes of Irish farmers

Background

Irish farmers represent a 'high-risk' group for non-communicable diseases, which, arguably, pose a greater occupational health challenge for farmers. To date, there has been little exploration of the farming characteristics associated with farmers' poor health outcomes.

Aims

To examine the relationship between farming and male farmers' self-reported health outcomes and to compare the study findings to national health studies to explore which factors specifically are associated with Irish farmers' poorer health outcomes relative to the general population.

Methods

This cross-sectional survey research used self-reported quantitative data on the health outcomes and health behaviours of male farmers from the South-East of Ireland. Data were entered into SPSS and descriptive and binary regression techniques were used for data analysis.

Results

There were 314 participants (99% response rate). Age, full-time farming and dairy farming significantly impacted self-reported health outcomes and health behaviours. There was a high prevalence of self-reported arthritis compared with the national average of Irish males. 'Younger' farmers (<45 years) were more likely to engage in harmful health behaviours such as smoking and 'binge-drinking' one or more times per week.

Conclusions

This study identified self-reported patterns of risky lifestyle behaviours among particular subgroups of Irish farmers for whom targeted health interventions are warranted. Interventions are particularly important for younger farmers who may see themselves as invincible and impregnable to ill-health.

Mirror therapy and treadmill training for patients with chronic stroke: a pilot randomized controlled trial

BACKGROUND

Previous lower-limb mirror therapy research has focused on non-weight bearing interventions.

OBJECTIVES

The primary aim of this study was to investigate the effect and feasibility of a combination of mirror therapy and treadmill training on post-stroke lower-limb recovery compared to a placebo intervention.

METHODS

All patients (N = 30) walked on a treadmill for 30 min per day, 3 days per week, for 4 weeks. The mirror therapy and treadmill training group (n = 15) walked on the treadmill while viewing a reflection of their non-paretic limb in a mirror positioned in their mid-sagittal plane. The placebo group (n = 15) received no mirror visual feedback due to an altered mirror position.

PRIMARY OUTCOME MEASURES

Ten Metre Walk Test (10MWT) and Six Minute Walk Test (6MWT).

SECONDARY OUTCOME MEASURES

Modified Ashworth Scale (MAS) and Fugl-Meyer Assessment-Lower Extremity (FMA-LE). Feasibility was appraised by examining participant compliance and any adverse events.

RESULTS

No significant between group differences were demonstrated for the 10MWT, 6MWT or FMA-LE at post-training or 3-month follow-up assessment. A significant between group difference on the MAS was demonstrated in the reduction of ankle dorsiflexion muscle tone (p = 0.006) and ankle plantarflexion muscle tone (p = 0.01) in the mirror therapy group compared to the placebo group at post-training assessment but not at 3-month follow-up.

CONCLUSION

Our study reveals that in our group of patients with chronic stroke, mirror therapy combined with treadmill training facilitated significant reductions in ankle muscle tone (p < 0.05) compared to a placebo intervention.

Mirror therapy for improving lower limb motor function and mobility after stroke: A systematic review and meta-analysis

BACKGROUND

Mirror therapy has been proposed as an effective intervention for lower limb rehabilitation post stroke.

RESEARCH QUESTION

This systematic review with meta-analysis examined if lower limb mirror therapy improved the primary outcome measures of muscle tone and motor function and the secondary outcome measures balance characteristics, functional ambulation, walking velocity, passive range of motion (PROM) for ankle dorsiflexion and gait characteristics in patients with stroke compared to other interventions.

METHODS

Standardised mean differences (SMD) and mean differences (MD) were used to assess the effect of mirror therapy on lower limb functioning.

RESULTS

Nine studies were included in the review. Among the primary outcome measures there was evidence of a significant effect of mirror therapy on motor function compared with sham and non-sham interventions (SMD 0.54; 95% CI 0.24-0.93). Furthermore, among the secondary outcome measures there was evidence of a significant effect of mirror therapy for balance capacity (SMD -0.55; 95% CI -1.01 to -0.10), walking velocity (SMD 0.71; 95% CI 0.35-1.07), PROM for ankle dorsiflexion (SMD 1.20; 95% CI 0.71-1.69) and step length (SMD 0.56; 95% CI -0.00 to 1.12).

SIGNIFICANCE

The results indicate that using mirror therapy for the treatment of certain lower limb deficits in patients with stroke may have a positive effect. Although results are somewhat positive, overly favourable interpretation is cautioned due to methodological issues concerning included studies.

Analysis of head impacts during sub-elite hurling practice sessions

The reported incidence of head and neck injuries in hurling is 0.12 per 1000 hours, but no previous research has quantified head impact characteristics in this sport. Here, a wireless accelerometer and gyroscope captured head impacts, in 20 senior club level hurling players. Peak linear and rotational acceleration and impact location were recorded during three hurling training sessions, each player participating once. A mean of 27.9 impacts (linear acceleration >10g) per player, per session were recorded; 1314 impacts during a total exposure time of 247 minutes. Only 2.6% impacts had peak linear acceleration of >70g and 6.2% had peak rotational acceleration >7900 rad/s². There were significant differences in the number and magnitude of impacts, quantified by the accelerometer, between three training sessions of differing intensity (ŋ2 0.03-0.09, p < 0.001). This study represents a first step in quantifying head impacts during hurling, demonstrating the feasibility of this technology in the field. The sensors were able to discriminate between sessions of varying intensity. These data can be used to develop athlete monitoring protocols and may be useful in developing innovative helmet-testing standards for hurling. The potential for this technology to provide feedback has clinical utility for team medical personnel.

Attacking 22 entries in rugby union: running demands and differences between successful and unsuccessful entries

Global Positioning System (GPS) technology is commonly utilized in team sports, including rugby union. It has been used to describe the average running demands of rugby union. This has afforded an enhanced understanding of the physical fitness requirements for players. However, research in team sports has suggested that training players relative to average demands may underprepare them for certain scenarios within the game. To date, no research has investigated the running demands of attacking 22 entries in rugby union. Additionally, no research has been undertaken to determine whether differences exist in the running intensity of successful and unsuccessful attacking 22 entries in rugby union. The first aim of this study was to describe the running intensity of attacking 22 entries. The second aim of this study was to investigate whether differences exist in the running intensity of successful and unsuccessful attacking 22 entries. Running intensity was measured using meters per minute (m min^-1 ) for (a) total distance, (b) running distance, (c) high-speed running distance, and (d) very high-speed running distance. This study provides normative data for the running intensity of attacking 22 entries in rugby union. Forwards achieved greater high-speed running intensity in successful (3.6 m min^-1 ) compared to unsuccessful (1.8 m min^-1 ) attacking 22 entries. Forwards should try and achieve greater high-speed running intensity in attacking 22 entries to increase the likelihood of successful outcomes during this period of gameplay.
