Subclinical vitamin B-12 deficiency is common in the elderly. Encouraged by early indications, we investigated the plasma vitamin B-12 status in association with bone mineral content (BMC) and bone mineral density (BMD) in frail elderly people. Data of 194 free-living Dutch frail elderly (143 women and 51 men) were available. BMC and BMD were measured by dual energy X-ray analysis. Biochemical analyses were performed on plasma or serum including vitamin B-12, methylmalonic acid, homocysteine, 25-hydroxy vitamin D and parathyroid hormone. Women had higher plasma vitamin B-12 (288 and 238 pmol/L, respectively) and lower plasma homocysteine levels (15.8 and 21.3 [micro]mol/L, respectively) than men. Of the total explained variance of BMC and BMD in women (46 and 22%, respectively), 1.3-3.1% was explained by plasma vitamin B-12, in addition to weight and height or energy intake. In men, the variance of BMC and BMD was explained by weight, smoking and/or height (total [R.sup.2] was 53 and 25%, respectively), but not by plasma vitamin B-12. Osteoporosis occurred more often among women whose vitamin B-12 status was considered marginal or deficient than in women with a normal status, i.e., the prevalence odds ratios (after adjustment for weight, age and calcium intake) (95% confidence intervals) were 4.5 (0.8;24.8) and 6.9 (1.2;39.4), respectively. These results suggest that vitamin B-12 status is associated with bone health in elderly women. Future studies on bone health should take into account a possible role of vitamin B-12 status in different populations.

Determinants of the nutrition guidance practices of primary care physicians (PCPs) were studied using a mail questionnaire developed on the basis of focus group discussions, in-depth interviews, and literature review. The questionnaire was sent to a nationwide random sample of 1000 PCPs (in practice for between 5 and 15 years). The net response rate was 64%. Multiple regression analysis was used to identify determinants of nutrition guidance practices. The independent variables studied were the perceived barriers to nutrition guidance practices, characteristics of the respondents, and nutrition attitudes and beliefs of PCPs. As determinants of nutrition guidance practices, we identified both perceived barriers (which exert a negative influence) and driving forces (which exert a positive influence). The driving forces observed in PCPs were an active interest in the effect of nutrition on health and disease, a basic level of nutrition knowledge, and positive attitudes towards nutrition guidance practices. Although perceived barriers can be strong, negative determinants of being involved in nutrition guidance practices, in future, it may become more important to stress the driving forces that positively determine the involvement of PCPs in nutrition guidance practices.

Objective: To investigate the nutrition education provided by primary-care physicians (PCP).Design: An integrative review was used to examine literature on nutrition care provided by PCP from 2012 to 2018. A literature search was conducted in MEDLINE, PubMed, Cumulative Index of Nursing and Allied Health Literature (CINAHL) and Scopus using key search terms.Setting: USA, Netherlands, Germany, Denmark, UK, Lebanon, Australia and New Zealand.Participants: Primary-care physicians.Results: Sixteen qualitative and quantitative studies were analysed thematically using meta-synthesis informed by the COM-B model of behaviour (capability, motivation and opportunity), to understand the influences on PCP behaviours to provide nutrition care. PCP perceive that they lack nutrition capability. While PCP motivation to provide nutrition care differs based on patient characteristics and those of their own, opportunity is influenced by medical educators, mentors and policy generated by professional and governmental organisations.Conclusions: The development of PCP capability, motivation and opportunity to provide nutrition care should begin in undergraduate medical training, and continue into PCP training, to create synergy between these behaviours for PCP to become confident providing nutrition care as an integral component of disease prevention and management in contemporary medical practice.

Objective: Shifting towards a more sustainable food consumption pattern is an important strategy to mitigate climate change. In the past decade, various studies have optimised environmentally sustainable diets using different methodological approaches. The aim of the present review was to categorise and summarise the different approaches to operationalise the health aspects of environmentally sustainable diets.Design: Conventional keyword and reference searches were conducted in PubMed, Scopus, Web of Knowledge and CAB Abstracts. Inclusion criteria were: (i) English-language publication; (ii) published between 2005 and October 2015; (iii) dietary data collected for the diet as a whole at the national, household or individual level; (iv) comparison of the current diet with dietary scenarios; and (v) for results to consider the health aspect in some way.Setting: Consumer diets.Subjects: Adult population.Results: We reviewed forty-nine studies that combined the health and environmental aspects of consumer diets. Hereby, five approaches to operationalise the health aspect of the diet were identified: (i) food item replacements; (ii) dietary guidelines; (iii) dietary quality scores; (iv) diet modelling techniques; and (v) diet-related health impact analysis.Conclusions: Although the sustainability concept is increasingly popular and widely advocated by nutritional and environmental scientists, the journey towards designing sustainable diets for consumers has only just begun. In the context of operationalising the health aspects, diet modelling might be considered the preferred approach since it captures the complexity of the diet as a whole. For the future, we propose SHARP diets: environmentally Sustainable (S), Healthy (H), Affordable (A), Reliable (R) and Preferred from the consumer's perspective (P). [ABSTRACT FROM AUTHOR]

Objective: To investigate (i) how the SLIMMER intervention was delivered and received in Dutch primary health care and (ii) how this could explain intervention effectiveness.Design: A randomised controlled trial was conducted and subjects were randomly allocated to the intervention (10-month combined dietary and physical activity intervention) or the control group. A process evaluation including quantitative and qualitative methods was conducted. Data on process indicators (recruitment, reach, dose received, acceptability, implementation integrity and applicability) were collected via semi-structured interviews with health-care professionals (n 45) and intervention participant questionnaires (n 155).Setting: SLIMMER was implemented in Dutch primary health care in twenty-five general practices, eleven dietitians, nine physiotherapist practices and fifteen sports clubs.Subjects: Subjects at increased risk of developing type 2 diabetes were included.Results: It was possible to recruit the intended high-risk population (response rate 54 %) and the SLIMMER intervention was very well received by both participants and health-care professionals (mean acceptability rating of 82 and 80, respectively). The intervention programme was to a large extent implemented as planned and was applicable in Dutch primary health care. Higher dose received and participant acceptability were related to improved health outcomes and dietary behaviour, but not to physical activity behaviour.Conclusions: The present study showed that it is feasible to implement a diabetes prevention intervention in Dutch primary health care. Higher dose received and participant acceptability were associated with improved health outcomes and dietary behaviour. Using an extensive process evaluation plan to gain insight into how an intervention is delivered and received is a valuable way of identifying intervention components that contribute to implementation integrity and effective prevention of type 2 diabetes in primary health care.

Objective: Patients with overweight or obesity increasingly attend general practice, which is an ideal setting for weight-loss counselling. The present study is the first to investigate the quality of weight-loss counselling provided by practice nurses in general practice to patients with overweight or obesity, in order to identify points for improvement.Design: An observational checklist was developed to assess goal and implementation intentions and 'missed opportunities for lifestyle counselling'. Comparisons were made with overall consultation goals set by practice nurses, as measured in a post-visit questionnaire.Setting: Dutch general practice.Subjects: One hundred video-taped consultations (2010/2011) between practice nurses and patients with overweight or obesity.Results: Half of the consultations contained a goal intention, of which the majority aimed to change eating behaviour. Only part of these goal intentions could be considered implementation intentions. It appeared that actions (how elements) were not often included here. Lifestyle change was more often perceived as an overall consultation goal than weight change. Regarding patterns of overall consultation goals, the majority addressed only one lifestyle factor at a time. If practice nurses formulated weight change in their overall consultation goal, they also used goal or implementation intentions, especially for weight change. In a quarter of the consultations, practice nurses did not ask any further questions about weight, nutrition or physical activity to gain insight, which is an important 'missed opportunity for lifestyle counselling'.Conclusions: Matching implementation intentions to the broader overall consultation goals of practice nurses would be meaningful, leading to desired goal-directed behaviours and subsequent goal attainment.

Background In this review study, we are the first to explore whether the practice nurse (PN) can act as case manager lifestyle counselling regarding weight management in primary care. Methods Multiple electronic databases (MEDLINE, PsycINFO) were searched to identify relevant literature after 1995. Forty-five studies fulfilled the inclusion criteria. In addition, all studies were judged on ten quality criteria by two independent reviewers. Results Especially in the last three years, many studies have been published. The majority of the studies were positive about PNs' actual role in primary care. However, several studies dealt with competency issues, including disagreement on respective roles. Thirteen studies were perceived as high quality. Only few studies had a representative sample. PNs' role in chronic disease management is spreading increasingly into lifestyle counselling. Although PNs have more time to provide lifestyle counselling than general practitioners (GPs), lack of time still remains a barrier. In some countries, PNs were rather ambiguous about their role, and they did not agree with GPs on this. Conclusion The PN can play the role of case manager lifestyle counselling regarding weight management in primary care in the UK, and wherever PNs are working under supervision of a GP and a primary health care team is already developed with agreement on roles. In countries in which a primary health care team is still in development and there is no agreement on respective roles, such as the USA, it is still the question whether the PN can play the case manager role.

Background: Although lifestyle interventions have shown to be effective in reducing the risk for type 2 diabetes mellitus, maintenance of achieved results is difficult, as participants often experience relapse after the intervention has ended. This paper describes the systematic development of a maintenance programme for the extensive SLIMMER intervention, an existing diabetes prevention intervention for high-risk individuals, implemented in a real-life setting in the Netherlands. Methods: The maintenance programme was developed using the Intervention Mapping protocol. Programme development was informed by a literature study supplemented by various focus group discussions and feedback from implementers of the extensive SLIMMER intervention. Results: The maintenance programme was designed to sustain a healthy diet and physical activity pattern by targeting knowledge, attitudes, subjective norms and perceived behavioural control of the SLIMMER participants. Practical applications were clustered into nine programme components, including sports clinics at local sports clubs, a concluding meeting with the physiotherapist and dietician, and a return session with the physiotherapist, dietician and physical activity group. Manuals were developed for the implementers and included a detailed time table and step-by-step instructions on how to implement the maintenance programme. Conclusions: The Intervention Mapping protocol provided a useful framework to systematically plan a maintenance programme for the extensive SLIMMER intervention. The study showed that planning a maintenance programme can build on existing implementation structures of the extensive programme. Future research is needed to determine to what extent the maintenance programme contributes to sustained effects in participants of lifestyle interventions. [ABSTRACT FROM AUTHOR]

Background Implementation of interventions in real-life settings requires a comprehensive evaluation approach. The aim of this article is to describe the evaluation design of the SLIMMER diabetes prevention intervention in a Dutch real-life setting. Methods/Design The SLIMMER study is a randomised, controlled intervention study including subjects aged 40 through 70 years with impaired fasting glucose or high risk of diabetes. The 10-month SLIMMER intervention involves a dietary and physical activity intervention, including case management and a maintenance programme. The control group receives usual health care and written information about a healthy lifestyle. A logic model of change is composed to link intervention activities with intervention outcomes in a logical order. Primary outcome is fasting insulin. Measurements are performed at baseline and after 12 and 18 months and cover quality of life, cardio-metabolic risk factors (e.g. glucose tolerance, serum lipids, body fatness, and blood pressure), eating and physical activity behaviour, and behavioural determinants. A process evaluation gives insight in how the intervention was delivered and received by participants and health care professionals. The economic evaluation consists of a cost-effectiveness analysis and a cost-utility analysis. Costs are assessed from both a societal and health care perspective. Discussion This study is expected to provide insight in the effectiveness, including its cost-effectiveness, and delivery of the SLIMMER diabetes prevention intervention conducted in Dutch primary health care. Results of this study provide valuable information for primary health care professionals, researchers, and policy makers. [ABSTRACT FROM AUTHOR]

Objective: General practitioners (GP) are uniquely placed to guide their patients on nutrition and physical activity. The aims of the present study were to assess: (i) the extent to which GP guide on nutrition and physical activity; (ii) the determinants that cause GP to give guidance on nutrition and physical activity; and (iii) the extent to which these guidance practices have the same determinants.Design: Cross-sectional study, mail questionnaire.Setting: Dutch general practice.Subjects: Four hundred and seventy-two GP in practice for 5–30 years.Results: Our study showed that the majority of GP had similar practices for both nutrition and physical activity guidance. Fair associations were found between nutrition and physical activity guidance practices. More than half of the explained variance in the models of physical activity guidance practices was improved by the inclusion of nutrition guidance practices in the models. Moreover, GP reported higher frequencies of physical activity guidance practices than nutrition guidance practices. Nutrition guidance practices predicted the same physical activity guidance practices.Conclusions: The majority of GP had similar practices for nutrition and physical activity guidance. GP were more inclined to guide their patients on physical activity than on nutrition. Self-efficacy was found to be a determinant in most models for guidance practices. Guidance practices proved to be a mix of prevention and treatment components. Consequently, we advise raising the selfefficacy of GP by training in medical school and in continuing medical education. We also recommend the combination of both nutrition and physical activity guidance in general practice. [ABSTRACT FROM AUTHOR]

Background: Although many evidence-based diabetes prevention interventions exist, they are not easily applicable in real-life settings. Moreover, there is a lack of examples which describe the adaptation process of these interventions to practice. In this paper we present an example of such an adaptation. We adapted the SLIM (Study on Lifestyle intervention and Impaired glucose tolerance Maastricht) diabetes prevention intervention to a Dutch real-life setting, in a joint decision making process of intervention developers and local health care professionals. Methods: We used 3 adaptation steps in accordance with current adaptation frameworks. In the first step, the elements of the SLIM intervention were identified. In the second step, these elements were judged for their applicability in a real-life setting. In the third step, adaptations were proposed and discussed for those elements which were deemed not applicable. Participants invited for this process included intervention developers and local health care professionals (n=19). Results: In the first adaptation step, a total of 22 intervention elements were identified. In the second step, 12 of these 22 intervention elements were judged as inapplicable. In the third step, a consensus was achieved for the adaptations of all 12 elements. The adapted elements were in the following categories: target population, techniques, intensity, delivery mode, materials, organisational structure, and political and financial conditions. The adaptations either lay in changing the SLIM protocol (6 elements) or the real-life working procedures (1 element), or a combination of both (4 elements). Conclusions: The positive result of this study is that a consensus was achieved within a relatively short time period (nine months) between the developers of the SLIM intervention and local health care professionals on the adaptations needed to make SLIM applicable in a Dutch real-life setting. Our example shows that it is possible to combine the perspectives of scientists and practitioners, and to find a balance between evidence-base and applicability concerns. [ABSTRACT FROM AUTHOR]

The article focuses on a study which investigated the prospective association between dairy consumption and changes in weight and metabolic disturbances. It assessed the baseline dairy intake by a semi-quantitative food-frequency questionnaire in 1,124 participants of the Hoorn Study. It found that baseline dairy consumption was not associated with changes in fasting and post-load glucose concentrations, serum lipid levels or blood pressure, nor with the risk of developing the metabolic syndrome (MS) in 6.4 years.

Abstract: Objective: The objectives of this study were to identify nutrition communication styles of Dutch GPs, their strategies regarding nutrition communication and nutrition information seeking behaviours. Another aim is to provide a hypothetical model for nutrition communication style, including psycho-social and socio-demographic variables. Methods: Nine focus groups with 81 GPs were used to obtain GPs’ perceptions of nutrition communication. Data were analysed with the computer software program NUD*IST. Results: Five nutrition communication styles were identified, namely informational, reference, motivational, confrontational and holistic style. Referring to a dietician, providing advice according to Dietary Guidelines, and offering written education materials were mentioned as strategies regarding nutrition communication. GPs sought nutrition information in scientific studies, specialist literature, and postgraduate training courses. Conclusion: The informational style of nutrition communication was dominant among Dutch GPs. GPs hardly provided maintenance advice for nutrition behaviour. Many GPs referred patients to dieticians, who were viewed as colleagues. GPs tried to get basic information about nutrition by scanning the literature, but they were seldom actively involved in seeking specific nutrition information. Although GPs felt that patients expect expert nutrition information, they perceived their nutrition knowledge as restricted. Practice implications: We advise to raise self-efficacy of GPs regarding nutrition communication and to build good collaboration with dieticians. [Copyright &y& Elsevier]

Objectives: The appraisal and acceptance of micronutrient-dense versus identical regular foods among frail elderly are described. Methods: Four types of dairy and four types of fruit products, either enriched with multiple micronutrients or not, were consumed by 150 frail elders for 4 months. In the first 2 and last 2 weeks of the intervention, hedonic aspects were assessed. Afterward, evaluation forms were completed. Results: At the start, small but consistent differences existed between the enriched and the regular foods concerning the scores on pleasantness, desire to eat the product, and attitude toward the product. At the end, those ratings dropped slightly or stayed equal. Significant differences between groups emerged from the overall evaluation score: 6.4 +/- 1.6 and 7.7 +/- 1.7 respectively (p < .001). Discussion: Optimization of the hedonic parameters of nutrient-dense foods and major long-term attention for application in the daily elderly feeding pattern is of essential importance.
