RESUMEN
BACKGROUND: Eating in absence of hunger is quite common and often associated with an increased energy intake co-existent with a poorer food choice. Intuitive eating (IE), i.e., eating in accordance with internal hunger and satiety cues, may protect from overeating. IE, however, requires accurate perception and processing of one's own bodily signals, also referred to as interoceptive sensitivity. Training interoceptive sensitivity might therefore be an effective method to promote IE and prevent overeating. As most studies on eating behavior are conducted in younger adults and close social relationships influence health-related behavior, this study focuses on middle-aged and older couples. METHODS: The present pilot randomized intervention study aims at investigating the feasibility and effectiveness of a 21-day mindfulness-based training program designed to increase interoceptive sensitivity. A total of N = 60 couples participating in the NutriAct Family Study, aged 50-80 years, will be recruited. This randomized-controlled intervention study comprises three measurement points (pre-intervention, post-intervention, 4-week follow-up) and a 21-day training that consists of daily mindfulness-based guided audio exercises (e.g., body scan). A three-arm intervention study design is applied to compare two intervention groups (training together as a couple vs. training alone) with a control group (no training). Each measurement point includes the assessment of self-reported and objective indicators of interoceptive sensitivity (primary outcome), self-reported indicators of intuitive and maladaptive eating (secondary outcomes), and additional variables. A training evaluation applying focus group discussions will be conducted to assess participants' overall acceptance of the training and its feasibility. DISCUSSION: By investigating the feasibility and effectiveness of a mindfulness-based training program to increase interoceptive sensitivity, the present study will contribute to a deeper understanding of how to promote healthy eating in older age.

BACKGROUND: The positive effects of a healthy diet on older adults' health status are well established. Yet, inadequate health outcomes prevail. Insufficient healthy dietary styles may be related to the complexity of lay concepts regarding what constitutes a healthy diet. It is hence of importance to disentangle and understand such concepts in depth. The aim of this qualitative study was to explore diet-related intra-couple dynamics and to reconstruct dietary concepts and associated influencing factors among older couples METHODS: The qualitative sample consisted of 15 German couples with at least one partner aged between 50 and 70 years. Study participants were recruited using theoretical sampling. Dyadic guideline-based interviews were conducted from 2016 to 2017. The transcripts were analyzed by means of the Grounded Theory Method RESULTS: Diverse Dyadic dietary concepts emerged from the data material and were shown to be dynamically influenced - among others - within the context of the couple relationship. Three major components showed to be integral to Dyadic dietary concepts: Ideas of healthy diet, Taste and Body images. Moreover, in all of the couples interviewed, one of the partners developed the role of a "Health Expert", who was consensually considered to have more solid health expertise. Different expressions of the HE with corresponding couple dynamics were identified DISCUSSION: This study demonstrates the relevance of diet-related intra-couple dynamics in shaping Dyadic dietary concepts. Particularly, the role of the "Health Expert" within couples showed to decisively influence such concepts. Future research is needed to gain a greater in-depth knowledge on the related influencing factors and couple dynamics. Public health (nutrition) strategies targeting older couples should address such intra-couple dynamics such as the role the partners play for shaping Dyadic dietary concepts.
RESUMEN
To promote healthy diets in older age, a comprehensive understanding of factors influencing dietary behaviour and underlying preferences is essential. Romantic relationships are focal socialisation contexts, in which diet-related preferences and practices are dynamically negotiated. Our aim was to reconstruct intra-couple dynamics shaping dietary preferences and comparatively analyse relationship types among older couples. Data basis was the NutriAct Family Study - a German web-based cohort. Analyses were based on three a priori defined relationship types: 1) both partners' mutual adaptation of dietary preferences (symmetrical convergence), 2) unilateral adaptation (asymmetrical convergence) and 3) persistence of individual preferences. Relationship types were, among others, comparatively analysed using ANOVAs. Intra-couple dynamics within the asymmetrical convergence type were measured by multivariate logistic regression. The dyadic sample consisted of 398 couples resp. N = 796 individuals aged 63.99 years (SD = 6.15). All three relationship types were identified (symmetrical convergence: n = 62, 15.6 %; asymmetrical convergence: n = 199, 50.0 %; persistence: n = 137, 34.4 %). Within the asymmetrical convergence type, women were more likely to take a dominating role compared to their male partners (OR: 24.40; 95%CI: 14.37-41.41). This study demonstrates the fundamental influence of intra-couple dynamics on individual dietary preferences, whereby traditional gender roles have shown to play a central moderating role. Our study findings are relevant for the development and implementation of public health (nutrition) strategies, since they highlight the importance of understanding dietary preferences as jointly constructed and shaped in the intra-couple context, rather than as isolated, individually developed ones. In this context, future research directions and practical implications targeting not only individuals but involving couples are discussed.

BACKGROUND: Multidisciplinary management of obesity by primary care paediatricians, providing a promising approach to tackle childhood obesity includes cooperation with other health care professionals. However, facilitators for and barriers to multidisciplinary cooperation in ambulatory care are not yet well understood and are investigated in the present study. METHODS: A nationwide, cross-sectional survey of 83% of German primary care paediatricians was conducted, using a questionnaire based on qualitative expert interviews. Frequency of paediatricians' cooperation with external partners (i.e. nutrition counsellors; sports groups; interdisciplinary obesity centres; inpatient rehabilitation centres; and endocrinologists) was assessed. Individual and structural factors were associated with cooperation patterns. Missing values were addressed using multiple imputation. RESULTS: Out of the 6081 primary care paediatricians approached, 2024 (33.3%) responded. Almost half of the respondents (40.8%) stated that they disengaged in the field of obesity prevention due to perceived inefficacy. Lack of financial reimbursement for consultation was agreed on by most of the respondents (90.4%). Identified barriers to cooperation included: higher proportion of patients with migration background, lack of time and available services. A more comprehensive conception of the professional role regarding overweight prevention, higher age, female gender, higher proportion of overweight/obese patients and practice location in urban or socially strained areas surfaced as facilitators for cooperation. CONCLUSION: Low-perceived self-efficacy in obesity management and insufficient financial reimbursement for consultation are commonly stated among German paediatricians. For cooperation behaviour, however, other individual and structural factors seem to be relevant, which provide indications on how multidisciplinary childhood obesity management can be improved.

BACKGROUND: Children and adolescents from families with a migration background and/or low social status belong to risk groups for the development of overweight. At the same time, they are considered difficult to approach for health promotion. This paper aims to provide an overview of freely available print and web-based materials on health promotion and to evaluate these in terms of formal, content-related, and target-group-specific criteria. METHOD: From August to September 2017, print media and websites were screened using systematic keyword searches in a large search engine. Search results were evaluated by an evidence-based catalogue of criteria and rated by comparative analysis. Health apps freely available from an app store were investigated, tested, and evaluated descriptively. RESULTS: Eighty-nine print media, 58 websites and 32 apps were found. Of the print media items, 11.2% are available in different languages; in 29% culturally sensitive aspects are considered and in 12.4% the material makes use of clear, nontechnical language. In 40.6% of the websites, either another language can be chosen or foreign language downloads are available. Most common are translations into English (37.5%), Turkish (31.3%), Arabic (28.1%), and Russian (25%). In 37.5% of the websites, the material addresses culturally sensitive aspects. From the tested apps (nâ¯= 25), only a few qualitatively high-ranked ones are aimed at parents and pregnant women and these are often text-based and exclusively available in German. DISCUSSION: Only few informational materials are directly oriented to the everyday world of risk groups. For this target group, material drawn up in clear language with multiple translations as well as with culturally adapted designs is recommended.

Background: The utilization of mobile health (mHealth) devices such as nutrition and fitness tools seems to be promising in facilitating healthy lifestyle behaviors in middle-aged and older adults. As user acceptance plays a decisive role in the successful implementation of mHealth tools, it is vital to examine the target groups' acceptance, particularly their usage behavior and attitudes toward these tools. This qualitative study aimed to explore how far middle-aged as well as older adults accept mobile nutrition and fitness tools and to identify facilitators and barriers shaping their acceptance. Methods: Twenty-one qualitative semi-structured interviews were conducted with German adults aged 50 years and older. Data material was analyzed using Qualitative Content Analysis (Kuckartz). Results: A comprehensive acceptance typology with three acceptance types could be reconstructed: The Rejection Type, The Selective Acceptance Type, and The Comprehensive Acceptance Type. The target group's acceptance of mobile nutrition and fitness tools appeared to differ considerably across the three acceptance types and between the two different types of mHealth tools - with mobile nutrition tools having been less accepted. Among others, high levels of usability were identified as a key facilitator, while a desire for autonomy and privacy concerns showed to be prominent barriers. Conclusion: The resulting typology indicates a pronounced heterogeneity among middle-aged and older adults regarding their acceptance of mobile nutrition and fitness tools. The findings highlight a need for more individualized mHealth tools along with respective promotion strategies that are specifically tailored to the needs and expectations of middle-aged and older adults.
RESUMEN
Favorable diets often include restrictive practices that have proven health benefits, even if initiated later in life. The aim of this qualitative study is to gain a comprehensive understanding of Restrictive Dietary Practices (RDPs) among a sample of middle-aged and older German adults (aged 59-78 years). We conducted 24 narrative in-depth interviews and analyzed the data using qualitative content analysis (Kuckartz). Following an inductive thematic approach, a typology was reconstructed comprising four typical RDP characteristics: I. The Holistically Restraining Type, II. The Dissonant-savoring Restraining Type, III. The Reactively Restraining Type, and IV. The Unintentionally Restraining Type. These types differed regarding the practical implementation of, e.g., restrictive food choice into everyday routines, barriers to do so, as well as with respect to attitudes and motives underlying RDPs. The major motives for adopting a RDP involved health, well-being, ethical, and ecological concerns. The most prominent barriers to a 'successful' adoption of RDPs were the enjoyment of food and the desire for spontaneity and freedom of (food) choice. Our study offers an in-depth understanding of the aspects that shape the widespread practice of dietary restriction among middle-aged and older adults. Lifeworld-related changes in RDPs and possible 'type shiftings' are discussed as well as the meaning and chances of RDPs for public health promotion.

BACKGROUND: To promote healthy aging, the support of digital mobile health tools such as mobile applications (apps) addressing a healthy diet or physical activity appears promising, particularly when initiated before entering old age. For such tools to be effective, middle-aged and older adults' acceptance need to be studied in depth. OBJECTIVE: The aim of this systematic review was to provide an integrative synthesis of the current state of research regarding the question in how far middle-aged and older adults (people aged 50 years and above) accept mobile nutrition and fitness apps to gain a deeper understanding of the influencing factors shaping this target group's usage behaviour and needs. METHODS: The review process followed the PRISMA guidelines. The databases Medline, Embase, Web of Science as well as reference lists were systematically searched. Study quality was assessed using the MMAT and AXIS appraisal tools. Data of the included studies were extracted and thereupon narratively synthesized, involving thematic analysis. RESULTS: Of N = 8823 articles screened, n = 7 studies could be identified-five quantitative, cross-sectional ones and two qualitative studies. Overall, the synthesized findings showed a lower acceptance among middle-aged and older adults compared to younger populations, which was particularly reflected in lower usage rates and more negative attitudes towards such apps (e.g., Perceived usefulness, Ease of use). The target group's acceptance of fitness apps was greater compared to nutrition apps. Findings on contextual factors and social determinants were inconsistent (e.g., regarding gender differences). CONCLUSION: While cross-study comparability was limited, the synthesized evidence underscores the importance to target mobile nutrition and fitness apps to the distinctive and heterogeneous needs of middle-aged and, particularly, of older adults. The scarcity of the existing body of knowledge highlights the need of further (longitudinal) research. PROSPERO PROTOCOL REGISTER NUMBER: CRD42020159409.
