Nutrition-focused group intervention with a strength-based counseling approach for people with clinical depression: a study protocol for the Food for Mind randomized controlled trial.

ABSTRACT:

Background

Depression is a highly prevalent mental disorder with major public health effects globally. It impairs the quality of life and reduces the ability to work and function, leading to increasing costs of sick leaves and disability pensions. Current treatment strategies focus on biological and psychological pathways while understating the role of lifestyle factors. Epidemiological studies have shown convincing evidence of an inverse relationship between diet quality and depression. However, only limited data are available on the therapeutic effects of diet quality improvement on depression. Using a randomized controlled trial design, our primary aim is to investigate the effectiveness and cost-effectiveness of a behavioral nutrition group intervention compared to a social support intervention in the treatment of depression.

Methods

Participants (N=144, aged 20-65 years) with a diagnosis of moderate or severe depression recruited in collaboration with outpatient care units will be randomized into two arms: Food for Mind (FM) nutrition intervention (n=72) or Bring Good Mood (BGM) social support control group (n=72). Both arms will be provided with 6 group sessions over an 8-week period. FM involves improving diet quality by applying strength-based behavioral nutrition counseling and activities facilitated by a registered dietitian. The control arm comprises a befriending protocol. During the interventions, all participants will continue their treatment for depression as usual. Longitudinal data are collected at baseline, at 8 weeks, and at 6- and 12-month follow-ups. Depressive symptoms, diet quality, eating behavior, ability to work and function, and quality of life are assessed by self-reported questionnaires. A treatment expectancy questionnaire will be administered at baseline and an acceptability questionnaire at 8 weeks. The Center for Epidemiologic Studies Depression Scale is used as the primary endpoint at 1 year. The results will be analyzed with linear mixed-effects models. Economic evaluation includes both cost-effectiveness and cost-utility analysis. Two incremental cost-effectiveness ratios will be calculated to evaluate the incremental cost per QALY and the incremental cost per improvement in CES-D.

Discussion

If the intervention proves to be cost-effective and acceptable, it be can be implemented in healthcare to support the treatment of depression.

Project description:Background: Only limited information is available on the nutrition knowledge of the general Austrian population and how this relates to the nutrition knowledge of health professionals (medical doctors, pharmacists, nutritionist, dieticians) and school teachers. Methods: Adolescents and adults at the age of 14–75 years (n = 1000), medical doctors (n = 307), pharmacists (n = 295), nutritionists (n = 124), dieticians (n = 160) and school teachers (n = 873) completed an online survey using a German version of the General Nutrition Knowledge Questionnaire-Revised (GNKQ-R) including self-reported data on sex, age, BMI, and health status. Adolescent and adult participants were recruited by a research agency to be representative for the Austrian population for age, sex, and education. A convenience sample was used for health professionals (medical doctors, pharmacists, nutritionist, dieticians) and school teachers. All participants completed a computer-assisted web-based interviewing (CAWI) survey. Results: Total scores for nutrition knowledge of the general population (61.4%) were significantly lower than scores from all other groups (medical doctors 81.3%, pharmacists 83.0%, dieticians 87.5%, nutritionists 85.6%, school teachers 74.5%). The main drivers for better nutritional knowledge were female sex, higher age, and higher level of education, while BMI classification and self-reported health status had no impact. In regard to single questions, the most striking result was the misclassification of sugar as the nutrient with the most calories by 41.4% of the general population while only 29.0% correctly identified fat to be the nutrient with the most calories. Conclusions: The nutritional knowledge of the general population should be significantly improved in order to lay a basis for better dietary behavior. In view of the relatively low scores of teachers, their nutrition education should be improved in order to enable transfer of sound education in schools.

Project description:IntroductionIt is widely known that the mind and the body, although described medically almost as separate entities, are in fact highly interrelated. This is not, however, always reflected within medical settings where physical interventions are often favoured over more holistic management, even in the case of long-term symptoms and/or pain where there is a strong evidence to favour the use of the latter. Mindfulness is an established and evidence-based intervention which can help people living with pain and physical symptoms. Interventions based on Compassion and Loving-kindness have also shown early promise but have not been fully explored. This study proposes a compassion-focused conceptualisation of persistent pain and reports on an intervention based upon this formulation.MethodsThe study took place within a routine clinical setting. Standardised outcome measures were collected pre- and post-intervention and effect sizes calculated for mean differences on each measure. Written qualitative comments that participants attributed to the group were also collected post-intervention and analysed with a thematic analysis. This was an uncontrolled, unpowered study conducted within a clinical setting which aimed to examine the intervention for any initial evidence of promise and to explore how it would be received by patients.ResultsThe results of the study indicated that engagement of patients in the intervention was reasonable. Improvements were recorded in pain distress (effect size (ES), 0.47) and intensity (ES, 0.23), anxiety (ES, 0.72), depression (ES, 0.46) and self-efficacy (ES, 0.36). Following the intervention, patients described changes that were grouped into the categories of feeling different, doing things differently and changed attitude.ConclusionThis exploratory study has demonstrated that a group-based intervention based on a model of compassion and including mindfulness and loving-kindness exercise has potential as an intervention to be used within routine pain management settings.
