RESUMO
BACKGROUND: Sustainable diets contribute to improving human health and reducing food-related greenhouse gas emissions (GHGE). Here, we established the effects of a facility-based sustainable diet intervention on the adherence to the EAT-Lancet Planetary Health Diet and GHGE of consumers. METHODS: In this quasi-experiment, vegan menus and educational material on sustainable diets were provided in the largest cafeteria of a German hospital for 3 months. Regular customers (> 1/week) in this cafeteria (intervention group) and in all other hospital cafeterias (control group) completed a questionnaire about their sociodemographic and dietary characteristics before and after the intervention period. We calculated difference-in-differences (DID), their 95% confidence intervals (CIs), and p-values for the adherence to the EAT-Lancet Planetary Health Diet Index (PHDI; 0-42 score points) and food-related GHGE. The protocol was registered at the German Clinical Trial Register (reference: DRKS00032620). FINDINGS: In this study population (N = 190; age range: 18-79 years; women: 67%; highest level of formal education: 63%), the mean baseline PHDI (25·1 ± 4·8 vs. 24·7 ± 5·8 points) and the mean baseline GHGE (3·3 ± 0·8 vs. 3·3 ± 0·7 kg CO2-eq./d) were similar between the intervention (n = 92) and the control group (n = 98). The PHDI increase was 0·6 points (95% CI: -0·4, + 1·6) higher in the intervention group than in the control group. This trend was stronger among frequent consumers of the vegan menu than among rare and never consumers. No between-group difference was seen for GHGE changes (DID: 0·0; 95% CI: -0·2, + 0·1 kg CO2-eq./d). INTERPRETATION: Pending verification in a longer-term project and a larger sample, this quasi-experiment in a big hospital in Germany suggests that offering vegan menus and information material in the cafeteria enhances the adherence to healthy and environmentally friendly diets among regular customers. These findings argue for making sustainable food choices the default option and for improving nutrition literacy.

BACKGROUND: The EAT-Lancet Commission has developed dietary recommendations, named the EAT-Lancet diet, to promote healthy nutrition and sustainable food production worldwide. OBJECTIVES: We developed an adapted score for the EAT-Lancet diet for participants of the Multiethnic Cohort (MEC) Study and its relation with incidence of obesity and type 2 diabetes (T2D). METHODS: The MEC includes 5 ethnic groups followed since 1993-1996. Anthropometric characteristics and dietary intake were assessed by questionnaire at cohort entry (Qx1) and 10 y later (Qx3). To create the EAT-Lancet index (range: 0-48 points), a 3-point scoring system for 16 food groups standardized to 2500 kcal/d was applied. T2D cases were identified through repeated self-reports and administrative data. In a prospective design, obesity at Qx3 and T2D incidence were evaluated using Cox regression to estimate hazard ratios (HR) with 95% confidence intervals (95% CI) while adjusting for relevant covariates. RESULTS: Among 193,379 MEC participants, the overall mean of the EAT-Lancet index score was 25 ± 4 points and 46,140 new T2D cases were identified. Higher adjusted means were observed in females than males, in participants of Japanese American and Native Hawaiian ancestry, and in those with healthy weight than overweight or obese. Obesity was lower in cohort members with higher EAT-Lancet scores (HR: 0.76; 95% CI: 0.73, 0.79 for tertile 3 compared with 1). Although T2D incidence was 10% lower among participants in the highest (27-42 points) compared with the lowest (9-23 points) EAT-Lancet index tertile (HR: 0.90; 95% CI: 0.88, 0.92), the association was attenuated after BMI adjustment (HR: 0.97; 95% CI: 0.94, 0.99). This inverse association with T2D was restricted to African American and European American participants. CONCLUSIONS: These findings support the hypothesis that adherence to the EAT-Lancet diet is related to a lower risk of obesity, which may be partially responsible for the small reduction in T2D incidence.
RESUMO
BACKGROUND: In response to climate change (CC), medicine needs to consider new aspects in health counselling of patients. Such climate-sensitive health counselling (CSHC) may include counselling patients on preventing and coping with climate-sensitive diseases or on leading healthy and climate-friendly lifestyles. This study aimed to identify previous participation in and preferences for CSHC as well as associated sociodemographic and attitudinal factors among the general public in Germany. METHODS: We conducted a cross-sectional study in a population-based online panel in five German federal states (04-06/2022). We performed descriptive statistics and multivariable regression analysis to assess prior participation in CSHC and content preferences regarding CSHC, as well as associations between sociodemographic variables and general preference for CSHC. RESULTS: Among 1491 participants (response rate 47.1%), 8.7% explicitly reported having participated in CSHC, while 39.9% had discussed at least one CSHC-related topic with physicians. In the studied sample, 46.7% of participants would like CSHC to be part of the consultation with their physician, while 33.9% rejected this idea. Participants aged 21 to 40 years (versus 51 to 60), individuals alarmed about CC (versus concerned/cautious/disengaged/doubtful/dismissive), and those politically oriented to the left (vs. centre or right) showed greater preference for CSHC in the multivariable regression model. Most participants wanted to talk about links to their personal health (65.1%) as opposed to links to the health of all people (33.2%). CONCLUSIONS: Almost half of the participants in this sample would like to receive CSHC, especially those who are younger, more alarmed about CC and more politically oriented to the left. More research and training on patient-centred implementation of CSHC is needed.

BACKGROUND: Globally, a fifth of the children continue to face chronic undernutrition with a majority of them situated in the Low- and Middle-Income Countries (LMIC). The rising numbers are attributed to aggravating factors like limited nutrition knowledge, poor feeding practices, seasonal food insecurity, and diseases. Interventions targeting behaviour change may reduce the devastating nutrition situation of children in the LMICs. OBJECTIVE: For the co-design of a Behaviour Change Communication (BCC) intervention for young children in rural Kenya, we aimed to identify the experiences, barriers, facilitators, and preferences of caregivers and stakeholders regarding nutrition and health counselling. DESIGN: We employed a qualitative study design and used a semi-structured interview guide. The in-depth interviews were recorded, transcribed, and analysed using content analysis, facilitated by the software NVivo. SETTING: Health and Demographic Surveillance System (HDSS) area in Siaya County, rural Kenya. PARTICIPANTS: We interviewed 30 caregivers of children between 6 and 23 months of age and 29 local stakeholders with experience in implementing nutrition projects in Kenya. RESULTS: Nutrition and health counselling (NHC) was usually conducted in hospital settings with groups of mothers. Barriers to counselling were long queues and delays, long distances and high travel costs, the inapplicability of the counselling content, lack of spousal support, and a high domestic workload. Facilitators included the trust of caregivers in Community Health Volunteers (CHVs) and counselling services offered free of charge. Preferences comprised (1) delivering of counselling by CHVs, (2) offering individual and group counselling, (3) targeting male and female caregivers. CONCLUSION: There is a disconnect between the caregivers' preferences and the services currently offered. Among these families, a successful BCC strategy that employs nutrition and health counselling should apply a community-based communication channel through trusted CHVs, addressing male and female caregivers, and comprising group and individual sessions.

BACKGROUND: Climate change is the greatest threat to global health in the twenty first century, yet combating it entails substantial health co-benefits. Physicians and other health professionals have not yet fully embraced their responsibilities in the climate crisis, especially about their communication with patients. While medical associations are calling on physicians to integrate climate change into health counselling, there is little empirical evidence about corresponding perceptions of patients. OBJECTIVES: This study aimed to explore primary care patients' perceptions of climate-sensitive health counselling. METHODS: From July to December 2021, 27 qualitative interviews with patients were conducted and analysed using thematic analysis. A purposive sampling technique was applied to identify patients who had already experienced climate-sensitive health counselling in Germany. RESULTS: Patients' perceptions of climate-sensitive health counselling were characterised by a high level of acceptance, which was enhanced by stressing the link between climate change and health, being credible concerning physician's own climate-friendly lifestyle, building upon good therapeutic relationships, creating a sense of solidarity, and working in a patient centred manner. Challenges and risks for acceptance were patients' disinterest or surprise, time constraints, feared politicisation of consultations, and evoking feelings of guilt and shame. CONCLUSION: These findings suggest that primary care patients can accept climate-sensitive health counselling, if it follows certain principles of communication, including patient-centredness. Our findings can be useful for developing communication guidelines, respective policies as well as well-designed intervention studies, which are needed to test the health and environmental effects of climate-sensitive health counselling.
Climate-sensitive health counselling was accepted in a qualitative patient sample in Germany.Patient-centred communication and a link to individual health contributed to acceptance while time-constraints, politisation and feelings of guilt were potential challenges.Further research is needed to investigating patients' acceptance and effects of climate-sensitive health counselling in larger samples.

BACKGROUND: Sub-Saharan African populations undergo a nutrition transition towards diets associated with increased risk for metabolic and cardiovascular diseases. For targeted prevention, we aimed to characterize dietary patterns and determine their sociodemographic factors of adherence. METHODS: We recruited 1,018 adults aged > = 25 years from two formal and three informal settlements within the Health and Demographic Surveillance System, Ouagadougou, Burkina Faso, between February and April 2021. In a cross-sectional sample, a culture-specific food-propensity questionnaire with 134 food items and a sociodemographic questionnaire were used to collect the data. Exploratory dietary patterns were derived using principal component analysis, and sociodemographic factors of adherence were calculated using multivariable linear regression models. RESULTS: In this study population (median age: 42 years, interquartile range 21 years; male: 35.7%), the diet relied on starchy foods and other plant-based staples with rare consumption of animal-based products. We identified three dietary patterns, explaining 10.2%, 9.8%, and 8.9% of variation in food intake, respectively: a meat and egg-based pattern associated with younger age, male sex, better education, and economic situation; a fish-based pattern prevailed among women, higher educational levels, and better economic situation; and a starchy food-based was associated with younger age and sharing a home with other adults. CONCLUSIONS: This study population is at an early stage of the nutrition transition and shows low intakes of health-beneficial food groups. Yet, progress along the nutrition transition varies according to age, educational attainment, and economic status. Particularly, younger and well-off people seem to adhere more strongly to diets high in animal-based products. These findings can inform strategies in public health nutrition for sub-Saharan African populations.

Health professional societies and researchers call for the integration of climate change into health counselling. However, the scientific evidence and conceptual grounding of such climate-sensitive health counselling (CSHC) remains unclear. We conducted a scoping review identifying scientific articles on the integration of climate change into communication between health professionals and patients in health-care settings. Scientific databases (Web of Science, PubMed, and Google Scholar) were searched from inception until Nov 30, 2022. 97 articles were included, of which 33 represented empirical research, and only two evaluated the effects of CSHC. More than half of the articles originated from the USA and addressed physicians. We introduce a conceptual framework for CSHC, which elaborates on aims, content areas, and communication strategies, and establishes the guiding principle of integrating CSHC into routine activities of health care. This framework supports health professionals in implementing CSHC and enables researchers to conceptualise intervention studies investigating how CSHC can contribute to the health of patients and the planet.

Adult-onset diabetes mellitus (here: aDM) is not a uniform disease entity. In European populations, five diabetes subgroups have been identified by cluster analysis using simple clinical variables; these may elucidate diabetes aetiology and disease prognosis. We aimed at reproducing these subgroups among Ghanaians with aDM, and establishing their importance for diabetic complications in different health system contexts. We used data of 541 Ghanaians with aDM (age: 25-70 years; male sex: 44%) from the multi-center, cross-sectional Research on Obesity and Diabetes among African Migrants (RODAM) Study. Adult-onset DM was defined as fasting plasma glucose (FPG) ≥ 7.0 mmol/L, documented use of glucose-lowering medication or self-reported diabetes, and age of onset ≥ 18 years. We derived subgroups by cluster analysis using (i) a previously published set of variables: age at diabetes onset, HbA1c, body mass index, HOMA-beta, HOMA-IR, positivity of glutamic acid decarboxylase autoantibodies (GAD65Ab), and (ii) Ghana-specific variables: age at onset, waist circumference, FPG, and fasting insulin. For each subgroup, we calculated the clinical, treatment-related and morphometric characteristics, and the proportions of objectively measured and self-reported diabetic complications. We reproduced the five subgroups: cluster 1 (obesity-related, 73%) and cluster 5 (insulin-resistant, 5%) with no dominant diabetic complication patterns; cluster 2 (age-related, 10%) characterized by the highest proportions of coronary artery disease (CAD, 18%) and stroke (13%); cluster 3 (autoimmune-related, 5%) showing the highest proportions of kidney dysfunction (40%) and peripheral artery disease (PAD, 14%); and cluster 4 (insulin-deficient, 7%) characterized by the highest proportion of retinopathy (14%). The second approach yielded four subgroups: obesity- and age-related (68%) characterized by the highest proportion of CAD (9%); body fat-related and insulin-resistant (18%) showing the highest proportions of PAD (6%) and stroke (5%); malnutrition-related (8%) exhibiting the lowest mean waist circumference and the highest proportion of retinopathy (20%); and ketosis-prone (6%) with the highest proportion of kidney dysfunction (30%) and urinary ketones (6%). With the same set of clinical variables, the previously published aDM subgroups can largely be reproduced by cluster analysis in this Ghanaian population. This method may generate in-depth understanding of the aetiology and prognosis of aDM, particularly when choosing variables that are clinically relevant for the target population.

The Mediterranean diet is often proposed as a sustainable diet model. This study aimed to evaluate the associations between adherence to the Mediterranean diet and sustainability domains in a cohort of French adults, using multiple criteria including nutritional quality, environmental pressures, monetary cost and dietary pesticide exposure. Food intakes of 29 210 NutriNet-Santé volunteers were assessed in 2014 using a semi-quantitative FFQ. Adherence to the Mediterranean diet was evaluated using the validated literature-based adherence score (MEDI-LITE). The associations between the MEDI-LITE and various sustainability indicators were examined using ANCOVA models, adjusted for sex, age and energy intake. Higher adherence to the MEDI-LITE was associated with higher nutritional quality scores, better overall nutrient profile as well as reduced environmental impact (land occupation: Q5 v. Q1: -35 %, greenhouse gas emissions: -40 % and cumulative energy demand: -17 %). In turn, monetary cost increased with increasing adherence to the Mediterranean diet (Q5 v. Q1: +15 %), while higher adherents to the Mediterranean diet had overall higher pesticide exposure due to their high plant-based food consumption. In this large cohort of French adults, greater adherence to the Mediterranean diet was associated with nutritional and environmental benefits, but also with higher monetary cost and greater exposure to pesticides, illustrating the necessity to develop large-scale strategies for healthy, safe (pesticide- and contaminant-free) and environmentally sustainable diets for all.

Assessment of the relative impact of climate change on malaria dynamics is a complex problem. Climate is a well-known factor that plays a crucial role in driving malaria outbreaks in epidemic transmission areas. However, its influence in endemic environments with intensive malaria control interventions is not fully understood, mainly due to the scarcity of high-quality, long-term malaria data. The demographic surveillance systems in Africa offer unique platforms for quantifying the relative effects of weather variability on the burden of malaria. Here, using a process-based stochastic transmission model, we show that in the lowlands of malaria endemic western Kenya, variations in climatic factors played a key role in driving malaria incidence during 2008-2019, despite high bed net coverage and use among the population. The model captures some of the main mechanisms of human, parasite, and vector dynamics, and opens the possibility to forecast malaria in endemic regions, taking into account the interaction between future climatic conditions and intervention scenarios.

INTRODUCTION: The global obesity epidemic and its adverse health effects have reached sub-Saharan Africa. In some urban settings, like Burkina Faso's capital Ouagadougou, up to 43% of the adult population are overweight or obese. At the same time, modernised food systems are responsible for 26% of global greenhouse gas emissions, 50% of land use and 70% of freshwater use. International guidelines on the treatment of overweight and obesity recommend dietary intervention programmes that promote reduced calorie intake and increased physical activity. So far, weight loss interventions rarely consider sustainable dietary concepts, including healthfulness, affordability, cultural appropriateness and environmental friendliness. Therefore, we present a study protocol of a novel randomised controlled trial that aims to establish the effects of a sustainable weight loss intervention on cardiometabolic and environmental outcomes in urban Burkina Faso. METHODS AND ANALYSIS: We conduct a non-blinded randomised controlled trial, comparing a 6-month sustainable diet weight loss intervention programme (n=125) with a standard weight loss information material and 5 min oral counselling at baseline (n=125). Primary outcome is a reduction in fasting plasma glucose of ≥0.1 mmol/L. Outcome measures are assessed at baseline, after 6 months and after 12 months. ETHICS AND DISSEMINATION: Ethical approval for the study has been obtained from the Medical Faculty of Heidelberg University (S-376/2019) and from the Ministry of Health and the Ministry of Higher Education, Scientific Research and Innovation in Ouagadougou, Burkina Faso (No 2021-01-001). The results of the study will be disseminated to local stakeholders at a final project meeting and to the wider research community through peer-reviewed publications and conferences.

The practice recommendation is intended to supplement the existing guidelines on diabetes mellitus and provides practical recommendations for the diagnosis, therapy and care of people with diabetes mellitus who come from different linguistic and cultural back-grounds. The article deals with the demographic datas of migration in Austria and Germany; with therapeutic advice concerning drug therapy and diabetes education for patients with migration background. In this context socio-cultural spezifics are discussed. These suggestions are seen complementary to the general treatment guidelines of the Austrian Diabetes Society and German Diabetes Society. Especially for the fast months Ramadan thera are a lot of informations. The most important point is that the patient care must highly individualized and the management plan may differ for each patient.

BACKGROUND: The high prevalence of anemia in resource-constrained settings calls for easy-to-use, inexpensive screening tools. The Sanguina Smartphone App, an innovative tool for non-invasive hemoglobin estimation via color-sensitive, algorithm-based analysis of fingernail bed images, was validated in the United States. This study evaluates the performance of the App in a population with different socio-economic, ethnic, demographic and cultural composition in rural Bihar, India. METHODS: For 272 mainly adult patients of a private health centre, hemoglobin measurement with the App is compared with the gold standard laboratory blood analysis. For a second sample of 179 children attending pre-schools, hemoglobin measurement with the App is compared to the results of the HemoCue Hb 301, a point-of-care device using a small blood sample, serving as the reference standard for field-based settings. RESULTS: The App reaches ±4.43 g/dl accuracy and 0.38 g/dl bias of comparator values in the clinic-based sample, and ±3.54 g/dl and 1.30 g/dl, respectively in the pre-school sample. After retraining the algorithm with the collected data, the validity of the upgraded version is retested showing an improved performance (accuracy of ±2.25 g/dl, bias of 0.25 g/dl), corresponding to the results of the original validation study from the United States. CONCLUSIONS: The initial version of the App does not achieve the accuracy needed for diagnosis or screening. After retraining the algorithm, it achieves an accuracy sufficient for screening. The improved version with the potential for further adaptions is a promising easy-to-use, inexpensive screening tool for anemia in resource-constrained point-of-care settings.
Hemoglobin is a protein in the blood that is required to move oxygen around the body. Anemia is a condition that occurs when levels of hemoglobin are too low. Anemia can lead to serious problems with the heart and lungs. This study assesses the accuracy of using a Smartphone App to measure hemoglobin levels by taking photos of a person's nails in rural Bihar, India. Results from the App are compared with those obtained by measuring hemoglobin in blood samples. Initially, measurements of hemoglobin obtained using the App were inaccurate, however when the App was modified using data from some of the people in India, the App was more accurate. This study shows that the App can and should be adapted for use in different populations and can enable anemia to be diagnosed outside of hospitals and other healthcare settings.
RESUMO
OBJECTIVE: Physical and mental well-being are threatened by climate change. Since hospitals in high-income countries contribute significantly to climate change through their greenhouse gas (GHG) emissions, the medical ethics imperative of 'do no harm' imposes a responsibility on hospitals to decarbonise. We investigated hospital stakeholders' perceptions of hospitals' GHG emissions sources and the sense of responsibility for reducing GHG emissions in a hospital. METHODS: We conducted 29 semistructured qualitative expert interviews at one of Germany's largest hospitals, Heidelberg University Hospital. Five patients, 12 clinical and 12 administrative employees on different levels were selected using purposive maximum variation sampling. Interviews were transcribed verbatim and analysed using the framework approach. RESULTS: Concerning GHG emissions, hospital stakeholders perceived energy and waste as most relevant emission sources followed by mobility. Climate change mitigation in general was considered as important. However, in their role as patients or employees, hospital stakeholders felt less responsible for climate change mitigation. They saw providing best possible medical care to be the top priority in hospitals and were often concerned that patients' health could be jeopardised by climate change mitigation measures. CONCLUSION: Perceptions of most important emission sources did not coincide with those in literature, highlighting the need to inform stakeholders, for instance, about pharmaceuticals as important emission source. A frequently perceived conflict between reducing emissions and providing high-quality medical care could be eased, if reducing emissions would not only be justified as a contribution to mitigation, but also as a contribution to preventing ill health-a basic principle of medical ethics.

BACKGROUND: Climate change heavily affects child nutritional status in sub-Saharan Africa. Agricultural and dietary diversification are promising tools to balance agricultural yield losses and nutrient deficits in crops. However, rigorous impact evaluation of such adaptation strategies is lacking. This project will determine the potential of an integrated home gardening and nutrition counseling program as one possible climate change adaptation strategy to improve child health in rural Burkina Faso and Kenya. METHODS: Based on careful co-design with stakeholders and beneficiaries, we conduct a multi-center, cluster-randomized controlled trial with 2 × 600 households in North-Western Burkina Faso and in South-Eastern Kenya. We recruit households with children at the age of complementary feed introduction (6-24 months) and with access to water sources. The intervention comprises the bio-diversification of horticultural home gardens and nutritional health counseling, using the 7 Essential Nutrition Action messages by the World Health Organization. After 12-months of follow-up, we will determine the intervention effect on the primary health outcome height-for-age z-score, using multi-level mixed models in an intention-to-treat approach. Secondary outcomes comprise other anthropometric indices, iron and zinc status, dietary behavior, malaria indicators, and household socioeconomic status. DISCUSSION: This project will establish the potential of a home gardening and nutrition counseling program to counteract climate change-related quantitative and qualitative agricultural losses, thereby improving the nutritional status among young children in rural sub-Saharan Africa.

BACKGROUND: Germany has become an important immigration country and health services need to adopt to meet the needs of an increasingly multicultural population. For public health planning, it is essential to understand the aetiology of health problems among migrant populations. The main objective was to systematically identify, evaluate and synthesise population-based studies that investigated exposure-outcome relationships among migrant groups in Germany. METHODS: In November 2019, we searched PubMed and LIVIVO, and updated this search in November 2020, to identify peer-reviewed publications that fulfilled our eligibility criteria: English or German language; study on disease aetiology among major migrant groups in Germany, according to the latest microcensus; publication date from inception to 01 November 2020 and observational or experimental study designs. For quality appraisal, we used the Critical Appraisal Skills Programme checklists. Outcomes under investigation were categorised according to the WHO major disease groups, and their associations with risk factors were synthesised as a heat map. RESULTS: Out of 2407 articles retrieved, we included 68 publications with a total number of 864 518 participants. These publications reported on cross-sectional data (n=56), cohort studies (n=11) and one intervention study. The population groups most frequently studied were from the Middle East (n=28), Turkey (n=24), sub-Saharan Africa (n=24), Eastern Europe (n=15) and the former Soviet Union (n=11). The outcomes under study were population group specific. There were consistent associations of demographic and socioeconomic factors with ill health among migrants in Germany. DISCUSSION: In this systematic review, we observed low risk of bias in two-thirds of the studies. There is an increasing body of evidence for aetiological research on migrants' health in Germany. Still, the directions of associations between a wide range of risk factors and major disease groups seem only partially understood. PROSPERO REGISTRATION NUMBER: CRD42018085074.
