Nutrition care by primary-care physicians: advancing our understanding using the COM-B framework.

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.

Cost-effectiveness of the SLIMMER diabetes prevention intervention in Dutch primary health care: economic evaluation from a randomised controlled trial.

Background: Although evidence is accumulating that lifestyle modification may be cost-effective in patients with prediabetes, information is limited on the cost-effectiveness of interventions implemented in public health and primary health care settings. Evidence from well-conducted pragmatic trials is needed to gain insight into the realistic cost-effectiveness of diabetes prevention interventions in real-world settings. The aim of this study is to assess the cost-effectiveness of the SLIMMER lifestyle intervention targeted at patients at high risk of developing type 2 diabetes compared with usual health care in a primary care setting in the Netherlands.

Nutrition in medical education: a systematic review.

Background: In many countries, doctors are recommended to provide nutrition care to patients to improve the dietary behaviours of individuals and populations. Here, we present a systematic review that aims to critically synthesise literature on nutrition education provided to medical students.

Methods: In this systematic review, a literature search was done between May 1 and July 1, 2018, for articles on medical students' nutrition knowledge, skills, and confidence to counsel patients, from Nov 1, 2012, to Dec 31, 2018.

Food stories: Unraveling the mechanisms underlying healthful eating.

The biomedical model of health (BMH) studies the causes and origins of disease. When applied to nutrition research, eating is studied as a behavior that supports physical health. However, the lack of attention the BMH pays to social and historical circumstances in which health behaviors are constructed has been widely addressed in literature.

Determinants of lifestyle behavior change to prevent type 2 diabetes in high-risk individuals.

Background: Although there are many effective lifestyle interventions for type 2 diabetes (T2DM) prevention, insight into effective intervention pathways, especially of long-term interventions, is often lacking. This study aims to provide insight into the effective intervention pathways of the SLIMMER diabetes prevention intervention using mediation analyses.

Methods: In total, 240 participants at increased risk of T2DM were included in the analyses over 18 months.

Is the success of the SLIMMER diabetes prevention intervention modified by socioeconomic status? A randomised controlled trial.

Aim: To explore the role of socioeconomic status (SES) in participation, programme attendance, programme acceptability, adherence to lifestyle guidelines, drop-out, and effectiveness in the SLIMMER diabetes prevention intervention.

Methods: SLIMMER was a randomised controlled intervention, carried out in a real-world setting, targeting 40- to 70-year-old adults at increased risk of developing type 2 diabetes (n=316). The intervention group participated in a 10-month combined dietary and physical activity programme.

Effect and maintenance of the SLIMMER diabetes prevention lifestyle intervention in Dutch primary healthcare: a randomised controlled trial.

Background/objectives: To assess the effectiveness of the SLIMMER combined dietary and physical activity lifestyle intervention on clinical and metabolic risk factors, dietary intake, physical activity, and quality of life after 12 months, and to investigate whether effects sustained six months after the active intervention period ended.

Subjects/methods: SLIMMER was a randomised controlled intervention, implemented in Dutch primary healthcare. In total, 316 subjects aged 40-70 years with increased risk of type 2 diabetes were randomly allocated to the intervention group (10-month dietary and physical activity programme) or the control group (usual healthcare).

Operationalising the health aspects of sustainable diets: a review.

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.

Individual, social-environmental, and physical-environmental factors that underlie sense of coherence in Dutch adults.

Antonovsky's salutogenesis is a theoretical perspective on health development that explores physical, mental, and social factors that contribute to a 'healthy life orientation' and also a theoretical approach to behavior change. Previous studies applying salutogenesis show that a high sense of coherence (SOC), a composite measure from salutogenesis indicating one's capacity to cope with stress, is associated with a healthy life orientation and lifestyle behaviors, including healthy eating patterns. However, limited evidence exists on the factors that underlie SOC, which could be used to strengthen this capacity as a means to enable healthier eating.

Process evaluation of a randomised controlled trial of a diabetes prevention intervention in Dutch primary health care: the SLIMMER study.

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.

Applying the salutogenic framework to nutrition research and practice.

Much research has identified a sea of factors related to unhealthy diets to make sense of why people struggle to eat healthy diets. However, little is known of factors that empower healthy eating. Antonovsky's salutogenesis provides an innovative framework to study these factors and identify resources and mechanisms underlying healthy eating practices.

Profiling healthy eaters. Determining factors that predict healthy eating practices among Dutch adults.

Research has identified multiple factors that predict unhealthy eating practices. However what remains poorly understood are factors that promote healthy eating practices. This study aimed to determine a set of factors that represent a profile of healthy eaters.

Setting goal and implementation intentions in consultations between practice nurses and patients with overweight or obesity in general practice.

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'.

To what extent do primary care practice nurses act as case managers lifestyle counselling regarding weight management? A systematic review.

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.

Using the intervention mapping protocol to develop a maintenance programme for the SLIMMER diabetes prevention intervention.

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.

Feasibility and potential impact of the adapted SLIM diabetes prevention intervention in a Dutch real-life setting: the SLIMMER pilot study.

Objective: Pilot-testing of the adapted Study on Lifestyle intervention and Impaired glucose tolerance Maastricht (SLIM) and to determine its feasibility and likelihood of achieving desired impact.

Methods: Pilot intervention study (a 10-month combined lifestyle intervention) using a one group pre-test post-test design with on-going process measures (i.e.

Quality of weight-loss counseling by Dutch practice nurses in primary care: an observational study.

Background/objective: To assess the quality of weight-loss counseling provided by Dutch primary care practice nurses (PNs) to overweight and obese patients including both PNs' compliance with the Five A's Model for behavioral counseling in primary care, and the use of different communication styles. In addition, relationships between PN/patient characteristics (including Five A's) and communication styles will be examined.

Subjects/methods: In this observational study, 100 videotaped real-life consultations, collected in 2010/2011, were viewed using an observational checklist.

SLIMMER: a randomised controlled trial of diabetes prevention in Dutch primary health care: design and methods for process, effect, and economic evaluation.

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.

Effect of resistance-type exercise training with or without protein supplementation on cognitive functioning in frail and pre-frail elderly: secondary analysis of a randomized, double-blind, placebo-controlled trial.

Physical activity has been proposed as one of the most effective strategies to prevent cognitive decline. Protein supplementation may exert an additive effect. The effect of resistance-type exercise training with or without protein supplementation on cognitive functioning in frail and pre-frail elderly people was assessed in a secondary analysis.

Examining the content of weight, nutrition and physical activity advices provided by Dutch practice nurses in primary care: analysis of videotaped consultations.

Background/objective: To examine the content of Dutch practice nurses' (PNs') advices about weight, nutrition and physical activity to overweight and obese patients.

Subjects/methods: A 100 videotaped real-life PN consultations (The Netherlands, 2010/2011) with overweight or obese patients were selected. An observational checklist was developed to assess frequency and content.

The impact of protein supplementation on cognitive performance in frail elderly.

Purpose: Maintenance of cognitive abilities is important for elderly to stay independent. With the aging of the population, the call for modifiable factors is emerging. Dietary protein might improve cognitive performance; however, this has hardly been studied.

Adapting the SLIM diabetes prevention intervention to a Dutch real-life setting: joint decision making by science and practice.

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.

Nutrition and physical activity guidance practices in general practice: a critical review.

Objective: The aim of this critical review is to provide insight into the main outcomes of research on communication about nutrition and/or physical activity between GPs and patients for prevention or treatment of overweight and obesity.

Methods: Relevant studies were identified by a computerized search of multiple electronic databases (MEDLINE, PsycINFO) for all available papers between 1 January 1995 and 1 January 2012. In addition, two independent reviewers judged all studies on ten quality criteria.

Determinants of Dutch general practitioners' nutrition and physical activity guidance practices.

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.
