Patient information letters on nutrition: development and implementation

Advising Obese Adults about Diet and Physical Activity in Sousse, Tunisia

Background. To our knowledge no study has been conducted in Tunisia to describe practice of health care providers towards chronic disease risk factors, particularly among obese adults. Aim. This study is aimed at assessing the level of giving advice on diet and physical activity by health care providers for obese adults comparing to nonobese adults in Tunisia. Methods. A cross-sectional survey was carried out in 2010 for adults aged from18 to 65 years living in the region of Sousse. The questionnaires were administered by an interview made by trained data collectors to standardize the administration of the questionnaire. Anthropometric measurements of height and weight were obtained using a standardized protocol from each participant. Results. The findings from this study indicate that obesity is frequent among adults essentially among women and aged categories. It also shows that obese adults are not adequately diagnosed with few proportion of anthropometric measure evaluation among all the participants. Even if obese participants were significantly more advised than nonobese participants with, respectively, 28.5% to lose weight and 23.8% to increase physical activity, this proportion remains low.

Patient recall of receiving lifestyle advice for overweight and hypertension from their General Practitioner

Background

Overweight, obesity and hypertension can be prevented through improvements in lifestyle including nutrition and physical activity. General practitioners (GPs) in Australia have access to over 90% of the population in the course of a year and therefore, the general practice setting may be ideal to assist patients with lifestyle change for weight management and hypertension. The present study aimed to determine the proportion of overweight/obese patients that recalled receiving advice by their GP to make lifestyle changes for weight loss. Recall of advice received by hypertensive patients to reduce salt intake was also measured.

Methods

A face to face survey was conducted on a representative sample (urban, suburban and rural) of South Australian residents. Respondents provided information on height and weight (self-report), whether they had received lifestyle advice from their GP for weight loss, and for those with self reported hypertension if they had received advice to reduce dietary salt.

Results

The sample included 2947 South Australian adult residents (58% female; BMI (mean (SD)), 26.6 (5.3) kg/m²; age, 50.7 (18.0) years). Ninety-six percent had visited their GP in the past 12 months. Forty-one percent of males and 25% of females were overweight and 19% of males and 20% of females were obese. Twenty-seven percent of overweight/obese respondents reported receiving lifestyle advice for weight loss purposes. Of the 33% who reported they had hypertension, 34% reported receiving advice to reduce salt intake.

Conclusions

Less than 1/3 of overweight/obese patients reported that they had received lifestyle advice that could assist with weight loss from their GP. About a third of respondents with hypertension reported that they received advice to reduce salt intake. There are potentially missed opportunities in which GPs could provide re-enforcement of benefits of lifestyle changes with respect to weight and blood pressure control.

Nutrition care for adult cardiac patients: Australian general practitioners' perceptions of their roles

BACKGROUND

Australia has implemented systematic managed care for patients with chronic disease. Little is known about how GPs perceive their nutrition care role in this system.

OBJECTIVE

To examine GPs' perceptions of their roles in the nutrition care of cardiac patients and to identify factors that influence their role.

METHODS

Multi-methods research design. Semi-structured interviews were conducted with a sample (n = 30) GPs Victoria, Australia. The resulting narratives were used to develop a quantitative questionnaire to survey a random sample of GPs. Principal components analysis was conducted to reduce the role items to a small number of underlying dimensions. The association between roles and demographic variables were examined using stepwise multiple regressions.

RESULTS

In all, 248 GPs (30% response) participated. Three main roles were established: Influencing, Coordinating and Nutrition Educator role. Together, the roles explained 54% of the total variance. Demographic variables were not associated with these roles. The majority (mean = 88%) endorsed the items which loaded on to the Influencing and Coordinating (mean = 49%) roles. Short consultation time, use of prescribed medications and perception of patient attendance at cardiac rehabilitation reduced the priority for nutrition education.

CONCLUSIONS

This study highlights the importance of developing more effective team care arrangements for patients with chronic disease and working with the medical education colleges to develop education resources for doctors that include an explanation of the non-pharmaceutical as well as the pharmaceutical treatment for each chronic disease condition.

Nutrition guidance in The Netherlands: the role of the GP in the translation from population strategy to individual approach

An important pitfall of nutritional guidance in medical practice is how to deal with the prevention paradox: a nutritional advice that is good for the population as a whole is not necessarily proven effective for the individual patient. Evidence-based guidelines are needed to support GPs to translate these advices to the individual patient. We illustrate this with two examples: obesity and undernutrition. The Dutch Ministry of Health started a national partnership on overweight. The role of the Dutch College of GPs (NHG) in this process is to insert the GP's perspective and to 'translate' the multidisciplinary guideline into a practice guideline for GPs. A systematic review on nutritional deficiency in general practice in The Netherlands showed a prevalence ranging from 0% to 13%. The 'National Steering Committee Undernutrition' stimulates GPs to pay more attention to undernutrition, in collaboration with the Dutch College of GPs. The Cochrane Primary Health Care Field (Nijmegen) accommodates the Cochrane Diet and Nutrition Sub Field involving the inclusion of evidence from non-randomized studies, which are generally not included in Cochrane Reviews, but which form an important part of the evidence for the role of nutrition. From this international initiative, a national collaboration in The Netherlands between universities, researchers and the Dutch College was founded, which aims to support the foundation of practice-based nutrition counselling in the consulting room.

Evaluation of a brief pilot nutrition and exercise intervention for the prevention of weight gain in general practice patients

OBJECTIVE

To pilot-test a brief written prescription recommending lifestyle changes delivered by general practitioners (GPs) to their patients.

DESIGN

The Active Nutrition Script (ANS) included five nutrition messages and personalised exercise advice for a healthy lifestyle and/or the prevention of weight gain. GPs were asked to administer 10 scripts over 4 weeks to 10 adult patients with a body mass index (BMI) of between 23 and 30 kg m(-2). Information recorded on the script consisted of patients' weight, height, waist circumference, gender and date of birth, type and frequency of physical activity prescribed, and the selected nutrition messages. GPs also recorded reasons for administering the script. Interviews recorded GPs views on using the script.

SETTING

General practices located across greater Melbourne.

SUBJECTS AND RESULTS

Nineteen GPs (63% female) provided a median of nine scripts over 4 weeks. Scripts were administered to 145 patients (mean age: 54+/-13.2 years, mean BMI: 31.7+/-6.3 kg m(-2); 57% female), 52% of whom were classified as obese (BMI >30 kg m(-2)). GPs cited 'weight reduction' as a reason for writing the script for 78% of patients. All interviewed GPs (90%, n=17) indicated that the messages were clear and simple to deliver.

CONCLUSIONS

GPs found the ANS provided clear nutrition messages that were simple to deliver. However, GPs administered the script to obese patients for weight loss rather than to prevent weight gain among the target group. This has important implications for future health promotion interventions designed for general practice.

Potentials and pitfalls for nutrition counselling in general practice

This paper was based on collaborative research efforts from Wageningen University and the University Medical Centre St Radboud in The Netherlands and describes the rationale for web-based nutrition counselling applications in general practice as well as some of the frequently used models and theories (predominantly the Stages of Change Model). General practitioners can play an important role in cardiovascular risk reduction by giving nutrition counselling to patients at elevated cardiovascular risk. Unfortunately, general practitioners perceive barriers that may limit their nutrition counselling practices. Some of these barriers may be overcome using computer and Internet technologies. Computerized reminders for preventive services, and websites with reliable high-quality information may prove to be valuable additions to usual care. Cooperation with dietitians may also lead to improvements in nutrition counselling in general practice. For example, general practitioners could use their unique position to create awareness and motivation among patients. They could subsequently refer motivated patients to dietitians for detailed personal dietary advice.

The Cochrane Library: more systematic reviews on nutrition needed

The knowledge and relevance of nutrition as well as the demand for well-funded advices increase. The Cochrane Collaboration plays a leading role within the evidence-based medicine and practice. We advocate therefore more specialized nutritional interest within the Cochrane Collaboration. In case 'Nutrition' needs more attention within the Cochrane Library, one of the first priorities is deciding about whether to include non-randomized studies into the Specialized Register and generating lists of journals to handsearch for such a Specialized Register. Preparatory to these activities an inventory of Nutritional content within the Cochrane Library is needed. We estimate that reviews directly related to nutrition and those of borderline interest to nutrition represent less than 4% of all published reviews in The Cochrane Library.

Perceived relevance and information needs regarding food topics and preferred information sources among Dutch adults: results of a quantitative consumer study

OBJECTIVE

For more effective nutrition communication, it is crucial to identify sources from which consumers seek information. Our purpose was to assess perceived relevance and information needs regarding food topics, and preferred information sources by means of quantitative consumer research.

DESIGN

Based on qualitative studies, a quantitative questionnaire was developed and administered in face-to-face interviews.

SUBJECTS

The study population consisted of Dutch adults aged 18-80 y. A stratified sample of 923 adults was taken from the GfK ScriptPanel; 603 respondents completed the questionnaire.

RESULTS

Despite high perceived relevance of food topics regarding dietary guidelines (55-78%), most respondents indicated that they did not want more information about these topics (71-74%). Furthermore, our study revealed information needs regarding safety- and health-related food topics (up to 77% in some subgroups). Differences in perceived relevance and information needs were found in subgroups based on gender, age, perceived weight and socioeconomic status. Education offices of the food sector and the family doctor were mentioned for most food topics, who ranked among the highest regarding perceived reliability, perceived expertise, clearness and accessibility.

CONCLUSIONS

With respect to five food topics (losing weight, sports and nutrition, lowering cholesterol, carbohydrates and food composition), interested subgroups should receive tailored information. For other groups and food topics, a population-wide strategy should suffice, utilising the preferred information source. If people who are not yet interested become interested through a life event, information on demand can be put into action.

Nutrition guidance by family doctors in a changing world: problems, opportunities, and future possibilities

During the Third Heelsum International Workshop, Nutrition Guidance of Family Doctors Towards Best Practice, December 10-12, 2001, Heelsum, the Netherlands, 17 papers were presented. Each paper was discussed by all the participants at the workshop. These discussions were tape-recorded, transcribed, rearranged into topics, and summarized here. There are situations that call for nutrition advice to be given by general practitioners (GPs). GPs are trusted, they are not selling any particular food, and patients accept that their GPs may talk to them about diet. Compared with dietitians, GPs have much less time to advise about diet, so they must condense information. It is easier for a GP to give dietary advice if the patient is registered on the practice's list and if the GP can be paid for preventive work. Six topics seemed to be particularly new and challenging in our changing world: (1) Use of dietary supplements, herbal preparations, and functional foods; (2) patients as partners; (3) computers in practices; (4) evidence-based medicine; (5) the Internet; and (6) the obesity epidemic. These topics were reported as problems and then discussed as opportunities. The aim of the Heelsum Collaboration on General Practice Nutrition was to facilitate the nutrition work of GPs in their practices by researching the problems and barriers and by testing solutions. In line with this aim, some suggestions for research are provided.
