Co-designing nutrition interventions with consumers: A scoping review

BACKGROUND

There is little known about nutrition intervention research involving consumer co-design. The aim of this scoping review was to identify and synthesise the existing evidence on the current use and extent of consumer co-design in nutrition interventions.

METHODS

This scoping review is in line with the methodological framework developed by Arksey and O'Malley and refined by the Joanna Briggs Institute using an adapted 2weekSR approach. We searched Medline, EMBASE, PsycInfo, CINAHL and Cochrane. Only studies that included consumers in the co-design and met the 'Collaborate' or 'Empower' levels of the International Association of Public Participation's Public Participation Spectrum were included. Studies were synthesised according to two main concepts: (1) co-design for (2) nutrition interventions.

RESULTS

The initial search yielded 8157 articles, of which 19 studies were included (comprising 29 articles). The studies represented a range of intervention types and participants from seven countries. Sixteen studies were published in the past 5 years. Co-design was most often used for intervention development, and only two studies reported a partnership with consumers across all stages of research. Overall, consumer involvement was not well documented. No preferred co-design framework or approach was reported across the various studies.

CONCLUSIONS

Consumer co-design for nutrition interventions has become more frequent in recent years, but genuine partnerships with consumers across all stages of nutrition intervention research remain uncommon. There is an opportunity to improve the reporting of consumer involvement in co-design and enable equal partnerships with consumers in nutrition research.

Implementation research on noncommunicable disease prevention and control interventions in low- and middle-income countries: A systematic review

BACKGROUND

While the evidence for the clinical effectiveness of most noncommunicable disease (NCD) prevention and treatment interventions is well established, care delivery models and means of scaling these up in a variety of resource-constrained health systems are not. The objective of this review was to synthesize evidence on the current state of implementation research on priority NCD prevention and control interventions provided by health systems in low- and middle-income countries (LMICs).

METHODS AND FINDINGS

On January 20, 2021, we searched MEDLINE and EMBASE databases from 1990 through 2020 to identify implementation research studies that focused on the World Health Organization (WHO) priority NCD prevention and control interventions targeting cardiovascular disease, cancer, diabetes, and chronic respiratory disease and provided within health systems in LMICs. Any empirical and peer-reviewed studies that focused on these interventions and reported implementation outcomes were eligible for inclusion. Given the focus on this review and the heterogeneity in aims and methodologies of included studies, risk of bias assessment to understand how effect size may have been compromised by bias is not applicable. We instead commented on the distribution of research designs and discussed about stronger/weaker designs. We synthesized extracted data using descriptive statistics and following the review protocol registered in PROSPERO (CRD42021252969). Of 9,683 potential studies and 7,419 unique records screened for inclusion, 222 eligible studies evaluated 265 priority NCD prevention and control interventions implemented in 62 countries (6% in low-income countries and 90% in middle-income countries). The number of studies published has been increasing over time. Nearly 40% of all the studies were on cervical cancer. With regards to intervention type, screening accounted for 49%, treatment for 39%, while prevention for 12% (with 80% of the latter focusing on prevention of the NCD behavior risk factors). Feasibility (38%) was the most studied implementation outcome followed by adoption (23%); few studies addressed sustainability. The implementation strategies were not specified well enough. Most studies used quantitative methods (86%). The weakest study design, preexperimental, and the strongest study design, experimental, were respectively employed in 25% and 24% of included studies. Approximately 72% of studies reported funding, with international funding being the predominant source. The majority of studies were proof of concept or pilot (88%) and targeted the micro level of health system (79%). Less than 5% of studies report using implementation research framework.

CONCLUSIONS

Despite growth in implementation research on NCDs in LMICs, we found major gaps in the science. Future studies should prioritize implementation at scale, target higher levels health systems (meso and macro levels), and test sustainability of NCD programs. They should employ designs with stronger internal validity, be more conceptually driven, and use mixed methods to understand mechanisms. To maximize impact of the research under limited resources, adding implementation science outcomes to effectiveness research and regional collaborations are promising.

Effectiveness of Interventional Studies on Type 2 Diabetes: A Decade Systematic Review

Context: Educational interventions on type 2 diabetes can have life-saving effects. A closer analysis of studies in this area contributes to well-designed interventions. Objectives: We surveyed the effectiveness of interventional studies on type 2 diabetes in the last decade. Data Sources: The research papers were obtained from PubMed, Science Direct, Scopus, Web of Science, Google Scholar, SID, and Magiran for Persian and English language studies between 2010 and 2019. The PRISMA checklist was used to select the studies for systematic reviews. Study Selection: The criteria for article selection were experimental studies, quasi-experimental studies, clinical trials, and pre-treatment and post-treatment observations. Also, the exclusion criteria were case studies, short articles, cross-sectional studies, descriptive and analytic studies, letters to the editor, and systematic review papers. Finally, 24 studies (out of 1,374) were entered in our study. Data Extraction: An interventional study checklist was used to report the standard of studies: (1) consolidated standards of reporting trials with 25 items; (2) checklist for experimental design with nine items; (3) checklist for quasi-experimental studies with nine items; and (4) transparent reporting of evaluations with non-randomized designs with 22 items. Results: Twenty-four research papers entered the final analysis. Most studies were clinical trials with the intervention period ranging from one to 12 months. Patients were usually selected as the participants. The education interventions in most studies were lectures, questions/answers, group discussions, brainstorming, photo/film/slide display, group teaching, individual training, individual counseling, and group counseling. The main focus of the interventions was on physical activity and diet, with positive effects. Conclusions: Most interventions made on type 2 diabetes variables had positive effects. Therefore, it is recommended that in addition to diet and physical activity, other factors of type 2 diabetes be considered in educational interventions. Also, the most effective and appropriate teaching methods should be considered to prevent and control this disease.

Community-Based Participatory Research Interventions to Improve Diabetes Outcomes: A Systematic Review

PURPOSE

The purpose of this study was to conduct a systematic evaluation of community-based participatory research (CBPR) interventions on diabetes outcomes. Understanding of effective CBPR interventions on diabetes outcomes is limited, and findings remain unclear.

METHODS

A reproducible search strategy was used to identify studies testing CBPR interventions to improve diabetes outcomes, including A1C, fasting glucose, blood pressure, lipids, and quality of life. Pubmed, PsychInfo, and CINAHL were searched for articles published between 2010 and 2020. Using a CBPR continuum framework, studies were classified based on outreach, consulting, involving, collaborating, and shared leadership.

RESULTS

A total of 172 were screened, and a title search was conducted to determine eligibility. A total of 16 articles were included for synthesis. Twelve out of the 16 studies using CBPR approaches for diabetes interventions demonstrated statistically significant differences in 1 or more diabetes outcomes measured at a postintervention time point. Studies across the spectrum of CBPR demonstrated statistically significant improvements in diabetes outcomes.

CONCLUSIONS

Of the 16 studies included for synthesis, 14 demonstrated statistically significant changes in A1C, fasting glucose, blood pressure, lipids, and quality of life. The majority of studies used community health workers (CHWs) to deliver interventions across group and individual settings and demonstrated significant reductions in diabetes outcomes. The evidence summarized in this review shows the pivotal role that CHWs and diabetes care and education specialists play in not only intervention delivery but also in the development of outward-facing diabetes care approaches that are person- and community-centered.

Ottawa charter framework as a guide for type 2 diabetes prevention and control in Iran

The growth of T2DM in Iran is predicted to be even greater than the global trend. So a new public health movement to effectively prevent and manage T2DM is required more than ever. The solution has lain in the heart of the Ottawa Charter, the first international conference on health promotion more than 30 years ago. The charter contains five useful actions to facilitate the process of diseases prevention and control: 1) building healthy public policy, 2) creating supportive environments, 3) strengthening community action, 4) developing personal skills, and 5) reorienting health care services toward promotion of health. The charter articulates health in all policies and their frameworks. The aim of this review is to examine how the five actions have been implemented in Iran and can serve as a guide to prevent and control diabetes. Several national case studies will be examined to illustrate the challenges facing Iran's health system. It enables the identification and sharing of best practice between countries.

[Community-based research in therapeutic patient education: practices and contributions. A literature review]

INTRODUCTION

Community-based research (CBR) in health involves both researchers and people concerned by the results of the research. It aims to empower populations, using their exposure to the phenomenon being studied as a starting point. The use of CBR in the field of therapeutic patient education (TPE) is of interest, as the two share such characteristics as the desire to foster self-reliance and participation and a culture of interdisciplinarity.

AIM

To characterize CBR in the therapeutic patient education field.

METHODS

A literature search on PUBMED using the keywords ?community-based (participatory) research?, ?patient education?, ?self-care? and ?self-management? retrieved 121 articles. The analysis looked at the type of research, the characteristics of both the populations involved and the co-researchers, the collaborative actions (analysed using a grid from the literature), and the difficulties in implementing these actions.

RESULTS

Thirty-one studies were included. Ten consisted of methodological studies, which tended to show the added value of collaborating with users in implementing TPE programmes compared to standard methods. The remaining 21 studies described the co-design and/or co-execution of new educational programmes. We identified 5 collaborative actions that involved a preparatory phase of the research, and 17 collaborative actions that involved the prioritization, conduct, and analysis of the research and dissemination of the results. Preventive measures are needed for potential methodological, organizational, ethical, and emotional difficulties.

DISCUSSION

The 22 identified actions need to be confirmed by other studies. The analysis grid could ultimately become a tool for guiding researchers for their researches within the CBR framework.

Evidence based review of type 2 diabetes prevention and management in low and middle income countries

AIM: To identify the newest approaches to type 2 diabetes (T2DM) prevention and control in the developing world context.

METHODS: We conducted a systematic review of published studies of diabetes prevention and control programs in low and middle-income countries, as defined by the World Bank. We searched PubMed using Medical Subject Headings terms. Studies needed to satisfy four criteria: (1) Must be experimental; (2) Must include patients with T2DM or focusing on prevention of T2DM; (3) Must have a lifestyle intervention component; (4) Must be written in English; and (5) Must have measurable outcomes related to diabetes.

RESULTS: A total of 66 studies from 20 developing countries were gathered with publication dates through September 2014. India contributed the largest number of trials (11/66). Of the total 66 studies reviewed, all but 3 studies reported evidence of favorable outcomes in the prevention and control of type 2 diabetes. The overwhelming majority of studies reported on diabetes management (56/66), and among these more than half were structured lifestyle education programs. The evidence suggests that lifestyle education led by allied health professionals (nurses, pharmacists) were as effective as those led by physicians or a team of clinicians. The remaining diabetes management interventions focused on diet or exercise, but the evidence to recommend one approach over another was weak.

CONCLUSION: Large experimental diabetes prevention/control studies of dietary and exercise interventions are lacking particularly those that consider quality rather than quantity of carbohydrates and alternative exercise.
