Short-term patient-centered nutrition counseling impacts weight and nutrient intake in patients with systemic lupus erythematosus

Efficacy of lifestyle interventions in the management of systemic lupus erythematosus: a systematic review of the literature

We performed a systematic review to explore existing evidence regarding the efficacy of lifestyle interventions for the management of systemic lupus erythematosus (SLE). The search was conducted on the 22nd of June 2021 for publications between 1st of January 2000 and the date of search. Additional articles within the aforementioned timeframe and until December 2023 were added by hand searching. Databases utilized were Medline, Embase, Web of Science, and Cinahl. Lifestyle interventions were defined as any intervention encompassing one or more of the following: physical exercise, diet and nutrition, mental health, harmful exposures, sleep, and social relations. The Joanna Briggs Institute critical appraisal tools were used for risk of bias assessment. The search yielded 11,274 unique records, we assessed the full text of 199 records, and finally included 102 studies. Overall, the quality of the evidence is limited, and there were multiple sources of heterogeneity. The two domains most extensively researched were mental health (40 records) and physical exercise (39 records). Psychological interventions had a positive effect on depressive symptoms, anxiety, and health-related quality of life (HRQoL), whereas physical exercise improved fatigue, depressive symptoms, aerobic capacity, and physical functioning. Studies on diet and nutrition (15 records) support that low fat intake and Mediterranean diet may be beneficial for reducing cardiovascular risk, but large interventional studies are lacking. Studies on harmful exposures (7 records) support photoprotection and use of sunscreen. While studies imply benefits regarding disease burden and drug efficacy in non-smokers and regarding HRQoL in normal-weight patients, more survey is needed on tobacco smoking and alcohol consumption, as well as weight control strategies. Studies on social relations (1 record) and sleep (no records) were sparse or non-existent. In conclusion, psychosocial interventions are viable for managing depressive symptoms, and exercise appears essential for reducing fatigue and improving aerobic capacity and physical function. Photoprotection should be recommended to all patients. Lifestyle interventions should be considered a complement, not a substitute, to pharmacotherapy.

Patient-centered nutrition education improved the eating behavior of persons with uncontrolled type 2 diabetes mellitus in North Ethiopia: a quasi-experimental study

Background

Improving the clinical outcome of people with type 2 diabetes mellitus by modifying their eating behavior through nutrition education is an important element of diabetes self-management. Significant data from the literature supports this idea, however in the Ethiopian setting, there is a practice gap. Therefore, the purpose of this study was to assess how patient-centered nutrition education affected the eating behavior and clinical outcomes of people with uncontrolled type 2 diabetes mellitus.

Method

In this quasi-experimental trial, 178 people with uncontrolled type 2 diabetes were purposely assigned to the intervention (n = 89) or control (n = 89) arm. The intervention arm was given patient-centered nutrition education, whereas the control arm received the routine care. Eating behavior and clinical outcome indicators such as HbAc, lipid profile, anthropometric indices, and blood pressure were assessed in both groups at the start and completion of the intervention. All scale variables were tested for normality and log transformed when appropriate. The baseline characteristics of the intervention and control groups were compared using the t-test for continuous variables and the chi-square test for categorical variables. The effect of nutrition education was determined using a difference in differences (DID) approach. P < 0.05 was established as the criterion of significance.

Result

Food selection (DID = 15.84, P < 0.001), meal planning (DID = 31.11, P < 0.001), and calorie needs (DID = 37.65, P < 0.001) scores were statistically higher in the nutrition education arm. Furthermore, their overall eating behavior score (DID = 27.06, P < 0.001) was statistically greater than the controls. In terms of clinical outcomes, the overall picture reveals that the intervention did not outperform over the routine care. However, in comparison to the controls, the intervention arm showed clinically significant improvement in HbA1c (DID = -0.258, P = 0.485).

Conclusion

Patient-centered nutrition education has resulted in positive adjustments in the eating behavior of people with uncontrolled type 2 diabetes mellitus. Furthermore, it has shown a great potential for improving their glycemic control.

Systematic literature review informing the EULAR recommendations for the non-pharmacological management of systemic lupus erythematosus and systemic sclerosis

Through this systematic literature review, we assembled evidence to inform the EULAR recommendations for the non-pharmacological management of systemic lupus erythematosus (SLE) and systemic sclerosis (SSc). We screened articles published between January 2000 and June 2021. Studies selected for data extraction (118 for SLE and 92 for SSc) were thematically categorised by the character of their intervention. Of 208 articles included, 51 were classified as robust in critical appraisal. Physical activity was the most studied management strategy and was found to be efficacious in both diseases. Patient education and self-management also constituted widely studied topics. Many studies on SLE found psychological interventions to improve quality of life. Studies on SSc found phototherapy and laser treatment to improve cutaneous disease manifestations. In summary, non-pharmacological management of SLE and SSc encompasses a wide range of interventions, which can be combined and provided either with or without adjunct pharmacological treatment but should not aim to substitute the latter when this is deemed required. While some management strategies i.e., physical exercise and patient education, are already established in current clinical practice in several centres, others e.g., phototherapy and laser treatment, show both feasibility and efficacy, yet require testing in more rigorous trials than those hitherto conducted.

The impact of nurse-led nonpharmacological multidisciplinary holistic nursing care on fatigue patients receiving hemodialysis: a randomized, parallel-group, controlled trial

BACKGROUND

Fatigue is a symptom characterized by an elevated prevalence in patients undergoing hemodialysis, which may cause extreme mental and muscular debilitation, significantly influencing social interaction, life quality and well-being. However, the significance of fatigue to patients undergoing hemodialysis has not been recognized yet, and prevention and management of fatigue in this population have not been thoroughly investigated. Additionally, previous studies mainly focused on muscular fatigue, while mental fatigue has been seldom discussed. This study aims to investigate the interaction between nurses and multidisciplinary of nonpharmacological integrated care interventions (NICIs) and assess the impact of fatigue on patients undergoing hemodialysis.

METHODS

The integrative nonpharmacological care interventions in this study included walking, motivational interviewing (MI) and health education regarding behavioral self-management. A single-center randomized controlled trial was conducted in the dialysis center of the nephrological department in a tertiary affiliated hospital of medical university from January to June 2019. A total of 118 patients were selected and randomly divided into the intervention group (IG) and the control group (CG). Four patients dropped out during the study, and 114 patients were enrolled for the eventual analysis. The 60 patients in the IG received routine nursing combined with integrated care interventions, while the 54 patients in the CG received routine nursing only. This study lasted for six months.

RESULTS

The experimental group exhibited significant reductions of overall fatigue (2.26 vs. 0.48), mental fatigue (1.41 vs. 0.54), muscular fatigue (2.13 vs. 0.75), and some biochemical indicators (e.g., serum urea) (P<0.05), compared with the CG.

CONCLUSIONS

Nurses and multidisciplinary teams have been demonstrated to play a key role and interplay function in chronic disease management. Hence, the nurse-led multidisciplinary NICIs significantly alleviated total fatigue (muscular fatigue and mental fatigue) and improved other parameters.

TRIAL REGISTRATION

ChiCTR-IOR-16008621 (March 18, 2016).

The Effect of Nonpharmacological Integrated Care Protocols on Patients with Fatigue Undergoing Hemodialysis: A Randomized Controlled Trial

This study was designed to investigate the effects of nonpharmacological integrated care protocols on fatigue in patients with hemodialysis. This parallel randomized controlled trial was conducted on patients undergoing hemodialysis from May to October 2020 at the Dialysis Center of the Fifth Affiliated Hospital of Zunyi Medical University. The patients were randomized into an intervention group (accepting nonpharmacological integrated care protocols and standard care) or a control group (accepting standard care only) using a computer-generated random number. The nonpharmacological holistic care intervention used in this study involved a well-rounded multidisciplinary team that worked together to improve dietary compliance, medication adherence, and self-management to improve patients' care and promote self-management. From the 120 evaluated patients, 116 cases were eligible and analyzed. The results showed that patients from the intervention group had obviously reduced overall fatigue, mental fatigue, and muscular fatigue relative to the control group. The nonpharmacological integrated care protocols were interactive and promotive to each other. Meanwhile, the role and function of nurses in the management of chronic disease were demonstrated to be crucial.

Patient-centered care: Dietitians' perspectives and experiences

OBJECTIVE

To (1) explore RDNs' descriptions of patient-centered care (PCC), (2) measure Registered Dietitian Nutritionists' (RDNs) preferences for PCC and (3) identify factors that affect RDNs' PCC preferences.

METHODS

A survey instrument including two open-ended items exploring RDN descriptions of and experiences with PCC, the Patient-Practitioner Orientation Scale (PPOS), and various factors that could influence PCC (e.g., work intensification, work engagement, and work/demographic characteristics) was expert reviewed, pilot tested, and distributed electronically to 4697 RDNs. A regression analysis was conducted, and two open-ended items were qualitatively analyzed.

RESULTS

Three themes emerged when RDNs described PCC (n = 375): dietitian/patient relationship (95.7%), organizational influence (64.4%), and interprofessional teams (26.3%). RDNs (n = 318) scored 4.60/6 on the PPOS. Higher levels of work engagement were predictive of higher PPOS scores, and heavier workloads were predictive of lower PPOS scores (p < 0.05). Primary work position also influenced PPOS scores (p<0.05).

CONCLUSION

RDNs have varying personal definitions of and experiences with PCC, however there are common themes. RDNs generally prefer PCC and score moderately high on the PPOS.

PRACTICE IMPLICATIONS

To strengthen preferences for PCC, managers should create manageable workloads and prioritize work engagement. Continued emphasis on interprofessional collaboration with and organizational promotion of RDNs could improve PCC.

Immunomodulatory Effects of Diet and Nutrients in Systemic Lupus Erythematosus (SLE): A Systematic Review

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by multiple organ involvement, including the skin, joints, kidneys, lungs, central nervous system and the haematopoietic system, with a large number of complications. Despite years of study, the etiology of SLE remains unclear; thus, safe and specifically targeted therapies are lacking. In the last 20 years, researchers have explored the potential of nutritional factors on SLE and have suggested complementary treatment options through diet. This study systematically reviews and evaluates the clinical and preclinical scientific evidence of diet and dietary supplementation that either alleviate or exacerbate the symptoms of SLE. For this review, a systematic literature search was conducted using PubMed, Scopus and Google Scholar databases only for articles written in the English language. Based on the currently published literature, it was observed that a low-calorie and low-protein diet with high contents of fiber, polyunsaturated fatty acids, vitamins, minerals and polyphenols contain sufficient potential macronutrients and micronutrients to regulate the activity of the overall disease by modulating the inflammation and immune functions of SLE.

End-user perceptions of a patient- and family-centred intervention to improve nutrition intake among oncology patients: a descriptive qualitative analysis

Background

People with cancer are at high risk of malnutrition. Nutrition education is an effective strategy to improve patient outcomes, however, little is known regarding the impact of family and/or carer involvement in nutrition education and requires investigation. The purpose of the study was to evaluate PIcNIC (Partnering with families to promote nutrition in cancer care) intervention acceptability from the perspective of patients, families and health care providers.

Methods

A descriptive qualitative study was undertaken at an inpatient and an outpatient hospital setting in Australia and an outpatient/home setting in Hong Kong. A patient-and-family centred intervention including nutrition education, goals setting/nutrition plans, and food diaries, was delivered to patients and/or families in the inpatient, outpatient or home setting. Semi-structured interviews were used to explore perceptions of the intervention. 64 participants were interviewed; 20 patients, 15 family members, and 29 health care professionals. Data were analysed using deductive and inductive content analysis.

Results

Two categories were identified; 1) ‘context and intervention acceptability’; and 2) ‘benefits of patient- and family-centred nutrition care’. Within each category redundant concepts were identified. For category 1 the redundant concepts were: the intervention works in outpatient settings, the food diary is easy but needs to be tailored, the information booklet is a good resource, and the intervention should be delivered by a dietitian, but could be delivered by a nurse. The redundant concepts for category 2 were: a personalised nutrition plan is required, patient and family involvement in the intervention is valued and the intervention has benefits for patients and families. Converging and diverging perceptions across participant groups and settings were identified.

Conclusions

In this paper we have described an acceptable patient- and family-centred nutrition intervention, which may be effective in increasing patient and family engagement in nutrition care and may result in improved nutrition intakes. Our study highlights important contextual considerations for nutrition education; the outpatient and home setting are optimal for engaging patients and families in learning opportunities.

Erythrocyte membrane polyunsaturated fatty acid profiles are associated with systemic inflammation and fish consumption in systemic lupus erythematosus: a cross-sectional study

Objective

This study aimed to assess polyunsaturated fatty acid (PUFA) status and association with systemic inflammation and fish consumption in systemic lupus erythematosus (SLE).

Methods

Parameters of PUFA status including the proportion of omega-6 and -3 fatty acids in highly unsaturated fatty acids (omega-6%, omega-3%), essential fatty acids linoleic acid (LA) and alpha-linolenic acid (ALA), the omega-6 PUFA arachidonic acid (ARA) and the sum of key omega-3 PUFA eicosapentaenoic acid+docosahexaenoic acid (omega-3 status) were measured by gas chromatography in 68 SLE patients (88.2% female, aged 45.7±12.5 years). Associations with serum CRP, disease activity, damage and fish consumption were assessed by linear regression modelling adjusted for age, sex and body mass index. Associations are reported in terms of regression coefficients (β).

Results

Omega-6 PUFA were associated with higher CRP: omega-6% (β = 0.052, p = 0.02), the ratio of LA/ALA (β = 0.007, p = 0.02) and ARA (β = 0.308, p = 0.001). Conversely, omega-3% was associated with lower CRP (β = −0.051, p = 0.02). Increased dietary PUFA consumption from fish (g/day) was linked to a higher omega-3 status (β = 2.21, p = 0.02) and lower self-reported damage (Brief Index of Lupus Damage; β = −3.22, p = 0.02).

Conclusions

Omega-3 and omega-6 fatty acid status differentially reflect systemic inflammation in SLE and are linked to fish consumption.

Dysregulated serum lipid profile and its correlation to disease activity in young female adults diagnosed with systemic lupus erythematosus: a cross-sectional study

BACKGROUND

Recent studies showed that dyslipidemia could be a critical factor in the progression of cardiovascular disease in systemic lupus erythematosus (SLE). The aim of the present study was to describe the relationship between serum lipid profile and SLE disease activity in young female adults with SLE.

METHODS

Seventy-one female subjects diagnosed with SLE aged 20~30 years were enrolled. Serum lipid profile including TC, TG, HDL-C, LDL-C, VLDL-C, Apo A, Apo B, and Apo E were evaluated between control and young female SLE patients. Univariate correlation analyses were performed to explore the correlation between serum lipid levels and SLE disease activity.

RESULTS

Our results showed that TG and VLDL-C levels were significantly increased in young female SLE as compared to control, with TC, HDL-C, LDL-C, Apo A, and Apo B significantly reduced. Meanwhile, univariate correlation analyses showed negative correlations between SLE disease activity index and HDL-C, LDL-C, Apo A, and Apo B; with positive correlations between SLE disease activity index and TG and VLDL-C.

CONCLUSION

Serum lipid profile was significantly dysregulated in young female SLE patients. Moreover, SLE disease activity was correlated to the serum lipid levels, supporting the notion that the young patients with SLE might also have a higher risk of cardiovascular disease.

Exploring the Perceived Impact of the Chronic Disease Self-Management Program on Self-Management Behaviors among African American Women with Lupus: A Qualitative Study

Objective

To qualitatively explore the processes through which the Chronic Disease Self‐Management Program (CDSMP)—a peer‐led, group‐based educational intervention for people with chronic conditions—affects self‐management behaviors among African American women with systemic lupus erythematosus (SLE).

Methods

Using a longitudinal pre‐ and postintervention design, we conducted two waves of one‐on‐one, semistructured interviews with 24 purposefully sampled participants. Wave 1 interviews explored self‐management behaviors at baseline; wave 2 interviews focused on changes in these behaviors postintervention. Transcripts were analyzed using thematic analysis methods.

Results

Study participants perceived the CDSMP to be a valuable resource that helped them improve fundamental self‐management behaviors, including exercise, relaxation, diet, and medication adherence. We found, with few exceptions, that in this sample, women's reported changes in self‐management behaviors did not vary by participant age, education, SLE disease severity, or depression status. Our analysis suggests that the CDSMP had the most widespread perceived effects on relaxation and exercise. Strategies that generated improvements in relaxation and exercise included goal setting, action planning, encouragement to pursue low‐impact physical activity, and introduction of mindfulness techniques to better manage SLE symptoms.

Conclusion

Our findings suggest that African American women with SLE perceived the CDSMP as an effective educational self‐management intervention. The program can potentially catalyze improvements in self‐management behaviors in this population, regardless of demographic or disease characteristics.

The Prognostic Nutritional Index and Nutritional Risk Index Are Associated with Disease Activity in Patients with Systemic Lupus Erythematosus

The prognostic nutritional index (PNI), controlling nutritional status (CONUT) score and nutritional risk index (NRI) have been described as useful screening tools for patient prognosis in several diseases. The aim of this study was to examine the relationship between PNI, CONUT and NRI with clinical disease activity and damage in 173 patients with systemic lupus erythematous (SLE). Disease activity was assessed with the SLE disease activity index (SLEDAI-2K), and disease-related organ damage was assessed using the SLICC/ACR damage index (SDI) damage index. PNI and NRI were significantly lower in active SLE patients than in inactive SLE patients (p < 0.001 and p = 0.012, respectively). PNI was inversely correlated with the SLEDAI score (p < 0.001) and NRI positively correlated with SLEDAI and SDI scores (p = 0.027 and p < 0.001). Linear regression analysis adjusting for age, sex and medications showed that PNI was inversely correlated with SLEDAI (β (95% CI) = -0.176 (-0.254, -0.098), p < 0.001) and NRI positively correlated with SLEDAI (β (95% CI) = 0.056 (0.019, 0.093), p = 0.003) and SDI (β (95% CI) = 0.047 (0.031, 0.063), p < 0.001). PNI (odds ratio (OR) 0.884, 95% confidence interval (CI) 0.809⁻0.967, p = 0.007) and NRI ((OR) 1.067, 95% CI 1.028⁻1.108, p = 0.001) were independent predictors of active SLE. These findings suggest that PNI and NRI may be useful markers to identify active SLE in clinical practice.

Significance and impact of dietary factors on systemic lupus erythematosus pathogenesis

Systemic lupus erythematosus (SLE) is an autoimmune disease of unknown etiology, although its mechanisms involve genetic, epigenetic and environmental risk factors. Considering that SLE pathogenesis is yet to be explored, recent studies aimed to investigate the impact of diet, in terms of triggering or altering the course of the disease. To study the impact of diet on SLE pathogenesis, we conducted a search on Pubmed using the keywords 'diet and autoimmune diseases', 'diet and lupus', 'caloric restriction and lupus', 'polyunsaturated fatty acids and lupus', 'vitamin D and lupus', 'vitamin C and lupus' 'vitamin E and lupus' 'vitamin A and lupus' 'vitamin B and lupus', 'polyphenols and lupus', 'isoflavones and lupus', 'minerals and lupus', 'aminoacids and lupus', 'curcumin and lupus' and found 10,215 papers, from which we selected 47 relevant articles. The paper clearly emphasizes the beneficial role of personalized diet in patients with SLE, and the information presented could be used in daily practice. Proper diet in SLE can help preserve the body's homeostasis, increase the period of remission, prevent adverse effects of medication and improve the patient's physical and mental well-being.

Nutritional intervention in patients with juvenile systemic lupus erythematosus: protective effect against the increase in fat mass

Patients with juvenile systemic lupus erythematosus (JSLE) usually have an increase in fat mass and decrease in lean body mass. The purpose of this study was to assess the effect of a nutritional intervention on changes in body composition and food consumption of adolescents with JSLE compared with a control group and its variation over time and to assess the association of total fat mass with clinical parameters. This randomized controlled study evaluated 31 girls. Body composition and food intake were evaluated at baseline. The patients were randomly allocated into a nutritional intervention group and a control group. The intervention group received monthly nutritional guidelines for 9 months. After this period, evaluations were repeated. The carbohydrates intake decreased in the intervention group compared with the control group (p = 0.031) at the end of the study period. Additionally, a significant decrease was observed in the intake of energy (p = 0.023), carbohydrates (p = 0.031), protein (p = 0.024), total fat (p = 0.027), saturated fat (p = 0.012), and trans fat (p = 0.029) in the intervention group between baseline and the end of the study. There was an average increase of 3.7 kg (95% CI 0.8-6.5) in the total fat mass (p = 0.013) and 0.36 kg/m² (95% CI 0.10-0.62) in the appendicular fat mass (p = 0.007) in the control group during the study period; this finding was not observed in the intervention group. A 9-month nutritional intervention in JSLE patients improved their eating habits and protected against the excessive gain of weight and body fat.

A randomized trial of a motivational interviewing intervention to increase lifestyle physical activity and improve self-reported function in adults with arthritis

BACKGROUND

Arthritis is a leading cause of chronic pain and functional limitations. Exercise is beneficial for improving strength and function and decreasing pain. We evaluated the effect of a motivational interviewing-based lifestyle physical activity intervention on self-reported physical function in adults with knee osteoarthritis (KOA) or rheumatoid arthritis (RA).

METHODS

Participants were randomized to intervention or control. Control participants received a brief physician recommendation to increase physical activity to meet national guidelines. Intervention participants received the same brief baseline physician recommendation in addition to motivational interviewing sessions at baseline, 3, 6, and 12 months. These sessions focused on facilitating individualized lifestyle physical activity goal setting. The primary outcome was change in self-reported physical function. Secondary outcomes were self-reported pain and accelerometer-measured physical activity. Self-reported KOA outcomes were evaluated by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) for KOA (WOMAC scores range from 0 to 68 for function and 0 to 20 for pain) and the Health Assessment Questionnaire (HAQ) for RA. Outcomes were measured at baseline, 3, 6, 12, and 24 months. Multiple regression accounting for repeated measures was used to evaluate the overall intervention effect on outcomes controlling for baseline values.

RESULTS

Participants included 155 adults with KOA (76 intervention and 79 control) and 185 adults with RA (93 intervention and 92 control). Among KOA participants, WOMAC physical function improvement was greater in the intervention group compared to the control group [difference = 2.21 (95% CI: 0.01, 4.41)]. WOMAC pain improvement was greater in the intervention group compared to the control group [difference = 0.70 (95% CI: -0.004, 1.41)]. There were no significant changes in physical activity. Among RA participants, no significant intervention effects were found.

CONCLUSION

Participants with KOA receiving the lifestyle intervention experienced modest improvement in self-reported function and a trend toward improved pain compared to controls. There was no intervention effect for RA participants. Further refinement of this intervention is needed for more robust improvement in function, pain, and physical activity.

Cardiovascular Disease Prevention Counseling Program for Systemic Lupus Erythematosus Patients

OBJECTIVE

To determine if a cardiovascular disease (CVD) prevention counseling program for lupus patients decreases the prevalence of CVD risk factors.

METHODS

The assessment phase of a 3-year CVD prevention counseling program included the evaluation of CVD risk factors, diet, exercise habits, and medications. The education phase included discussion of the above risk factors, as well as CVD and thrombosis prevention strategies. Patients were prospectively followed every 3-6 months for risk assessment and continued education by a nurse practitioner and a medical doctor.

RESULTS

Between March 2009 and December 2014, 121 patients were included. At baseline, abnormal blood pressure, blood glucose, cholesterol profile, and body mass index were found in 50 (41%), 7 (6%), 82 (68%), and 77 (64%) patients, respectively. During the 3-year followup, among those with abnormal baseline values, prevalence of abnormal blood pressure significantly decreased (odds ratio [OR] 0.94, 95% confidence interval [95% CI] 0.92-0.96, P < 0.0001) with significant mean ± SD systolic blood pressure improvement (-6.12 ± 2.16 mm Hg; P < 0.05). The prevalence of abnormal cholesterol profile significantly decreased (OR 0.90, 95% CI 0.92-0.96) with significant improvements in mean ± SD high-density lipoprotein (+5.4 ± 0.36 mg/dl; P < 0.0001) and triglyceride levels (-12.6 ± 5.40 mg/dl; P < 0.05), and no significant change in blood glucose and body mass index was observed. At baseline, 100 (83%) and 95 (79%) patients had poor diet and physical activity, respectively; during the followup, both significantly improved in the entire population.

CONCLUSION

Our data suggest that a CVD prevention counseling program decreases the prevalence of some CVD risk factors in lupus patients.

Patient-centred care to improve dietetic practice: an integrative review

BACKGROUND

Patient-centred care (PCC) is associated with significant improvements in patients' health outcomes and healthcare systems. There is an opportunity to better understand PCC in dietetics. Thus, the present integrative review aims to critically synthesise literature relating to PCC in dietetics.

METHODS

A systematic literature search was conducted between February and March 2016. Studies were included if they (i) involved dietitians and/or patients who had participated in an individual dietetic consultation; (ii) related to one or more components of PCC; and (iii) were empirical full-text studies in English, involving adult participants, published between 1997 and 2016. Following title and abstract screening, full texts were retrieved and independently assessed for inclusion by two of the investigators. Two independent investigators conducted data extraction and quality assessment using the Mixed Methods Appraisal Tool. Study findings were analysed thematically using meta-synthesis. Twenty-seven studies met the inclusion criteria.

RESULTS

Six themes were discovered inductively: (i) establishing a positive dietitian-patient relationship; (ii) displaying humanistic behaviours; (iii) using effective communication skills; (iv) individualising and adapting care; (v) redistributing power to the patient; and (vi) lacking time for PCC practices. The first three themes were closely related. Studies used a broad range of methodological designs. Limitations of the studies included a lack of reflexivity and a lack of representativeness of the study population.

CONCLUSIONS

It is apparent that dietitians require good communication skills and humanistic qualities to build positive relationships with patients. Patients strongly desire individualised nutrition care and greater involvement in care. Ensuring dietitians are able to incorporate patient-centred practises during care requires further research.

Trends and disparities in the prevalence of physicians' counseling on diet and nutrition among the U.S. adult population, 2000-2011

BACKGROUND

Although healthy eating plays a crucial role in addressing the obesity and chronic disease epidemics, a few Americans have diets that meet dietary guidelines. Because physicians-delivered counseling is a strong predictor for behavioral modification among patients, the Healthy People Objectives have emphasized diet counseling since 2000. However, research on impact of physicians' counseling over time on a national level has been limited.

METHODS

We used data from the 2000 and 2011 National Health Interview Surveys to apply a logistic regression model to identify predictors of physicians' counseling and examine any changes in disparities over a decade.

RESULTS

In 2000, only 23.7% of our national sample had received dietary counseling, it increased to 32.6% in 2011. Hispanics were less likely than Whites to receive advice on diet in 2000 (adjusted odds ratio [AOR]=0.74, 95% confidence interval [CI]=0.62-0.88). By 2011, Hispanics 18% (AOR=1.18, CI=1.09-1.28) and Blacks were 42% (AOR=1.42, CI=1.32-1.54) more likely to receive advice from their physicians on diet than Whites. In both years, men were significantly less likely than women to receive counseling. The uninsured patients were increasingly less likely than insured patients in receiving diet counseling, being 60% less likely in 2011 (AOR=0.40, CI=0.37-0.40). Obese patients were substantially (88% in 2000 to 290% in 2011) more likely to receive counseling than normal-weight patients.

CONCLUSIONS

The overall prevalence of physicians' counseling on diet increased moderately between 2000 and 2011. However, substantial disparities in dietary counseling related to access to care and gender continue to exist.
