Impact of nutrition education on diabetes knowledge and attitudes of adults with type 2 diabetes living in a resource-limited setting in South Africa: a randomised controlled trial

Area-level deprivation and individual-level socioeconomic correlates of the diabetes care cascade among black south africans in uMgungundlovu, KwaZulu-Natal, South Africa

South Africa is experiencing a rapidly growing diabetes epidemic that threatens its healthcare system. Research on the determinants of diabetes in South Africa receives considerable attention due to the lifestyle changes accompanying South Africa's rapid urbanization since the fall of Apartheid. However, few studies have investigated how segments of the Black South African population, who continue to endure Apartheid's institutional discriminatory legacy, experience this transition. This paper explores the association between individual and area-level socioeconomic status and diabetes prevalence, awareness, treatment, and control within a sample of Black South Africans aged 45 years or older in three municipalities in KwaZulu-Natal. Cross-sectional data were collected on 3,685 participants from February 2017 to February 2018. Individual-level socioeconomic status was assessed with employment status and educational attainment. Area-level deprivation was measured using the most recent South African Multidimensional Poverty Index scores. Covariates included age, sex, BMI, and hypertension diagnosis. The prevalence of diabetes was 23% (n = 830). Of those, 769 were aware of their diagnosis, 629 were receiving treatment, and 404 had their diabetes controlled. Compared to those with no formal education, Black South Africans with some high school education had increased diabetes prevalence, and those who had completed high school had lower prevalence of treatment receipt. Employment status was negatively associated with diabetes prevalence. Black South Africans living in more deprived wards had lower diabetes prevalence, and those residing in wards that became more deprived from 2001 to 2011 had a higher prevalence diabetes, as well as diabetic control. Results from this study can assist policymakers and practitioners in identifying modifiable risk factors for diabetes among Black South Africans to intervene on. Potential community-based interventions include those focused on patient empowerment and linkages to care. Such interventions should act in concert with policy changes, such as expanding the existing sugar-sweetened beverage tax.

Knowledge of type 2 diabetic patients followed for less than 5 years in primary care in the western region of Reunion Island: a cross-sectional pilot study

Background

The learning needs of newly diagnosed diabetic patients followed up in medical offices in Reunion Island are unknown, although necessary for the improvement of education programmes and disease control.

Aim

To assess the knowledge of type 2 diabetic patients in primary care followed for less than 5 years.

Method

A cross-sectional study was carried out, using a self-questionnaire to assess patients' knowledge of diabetes, complications, follow-up, diet and physical activity. Patients were recruited from medical offices in the western region of Reunion Island.

Results

From 23^rd April to 31^st July 2021, 89 patients were included. The knowledge level of the total sample was moderate (mean correct answers 65 % ± 17). The best knowledge levels were in the areas "generalities on diabetes" and "complications", while the lowest levels were in the categories "follow-up" and "diet and physical activity". Glycated haemoglobin, libido disorders, frequency of urinalysis and dental consultation, and the recommended diet for patients with diabetes which is the same as for the general population, were the least known concepts.

Conclusion

This study revealed gaps in patients' knowledge that could be used to improve education programmes which in turn could reduce or prevent diabetes complications.

A Culturally Sensitive and Theory-Based Intervention on Prevention and Management of Diabetes: A Cluster Randomized Control Trial

Type 2 diabetes is an emerging concern in Kenya. This clustered-randomized trial of peri-urban communities included a theory-based and culturally sensitive intervention to improve diabetes knowledge, health beliefs, dietary intake, physical activity, and weight status among Kenyan adults. Those in the intervention group (IG) received a culturally sensitive diabetes education intervention which applied the Health Belief Model in changing knowledge, health beliefs and behavior. Participants attended daily education sessions for 5 days, each lasting 3 h and received mobile phone messages for an additional 4 weeks. The control group (CG) received standard education on COVID-19. Data was collected at baseline, post-intervention (1 week), and follow-up assessment (5 weeks). Linear mixed effect analysis was performed to assess within and across group differences. Compared to the control, IG significantly increased diabetes knowledge (p < 0.001), health beliefs including perceived susceptibility (p = 0.05), perceived benefits (p = 0.04) and self-efficacy (p = 0.02). IG decreased consumption of oils (p = 0.03), refined grains (p = 0.01), and increased intake of fruits (p = 0.01). Perceived barriers, physical activity, and weight status were not significantly different between both groups. The findings demonstrate the potential of diabetes education in improving diabetes knowledge, health beliefs, and in changing dietary intake of among adults in Kenya.

Community-based lifestyle intervention improves metabolic syndrome and related markers among Kenyan adults

Purpose

Metabolic syndrome (MetS) is a major risk factor for cardiovascular diseases and type-2 diabetes. The study aimed to establish the efficacy of a community-based lifestyle intervention on MetS in Kenyan adults using randomized control trial involving a 15-months follow up.

Methods

A randomized controlled trial involving 352 (18-64 years old) adults with MetS spanning 15-months duration. Participants were recruited from a Nairobi based Mission-led outpatient clinic, randomly assigned equally into intervention and control groups. The intervention group was exposed to a community-based health education on lifestyle modification, while control group was subjected to hospital-led routine care involving treatment and general lifestyle advice. The study was structured into baseline, intervention and evaluation phases with inbuilt data collection in each phase. Physiologic, anthropometric, and clinical parameters as well lifestyle characteristics were measured at baseline, midline and end-line. The parameters were compared across the groups and between the time points during analyses using chi-square test, binary logistic, independent t-test and paired t-test.

Results

Proportion of participants with MetS declined significantly (p < 0.001) with marked (p < 0.05) improvement in markers of MetS (elevated BP, raised sugars, cholesterols, central obesity) in intervention compared to control group. The rates of consumption of fruits, vegetables, legumes, nuts and uptake of physical activity significantly (p < 0.05) improved in the intervention group. However, the intake of processed/fast foods, salt, sugar, and alcohol significantly (p < 0.05) declined in the intervention compared to controls by the end-line.

Conclusion

One in three adults under the community-based lifestyle intervention had improvement in physiologic, anthropometrics and clinical markers relevant to definition of MetS. Additionally, an improved adherence to the recommended dietary intake and increased uptake of physical activity in adults with MetS was observed. These findings underscore the feasibility, effectiveness and proof of concept for community-based lifestyle approach as a viable strategic intervention for addressing premorbid risk factors for cardiovascular CVDs and diabetes before evolving into full blown conditions in low-income settings.

The Individual Nutrition Education Needs among Patients with Type 2 Diabetes at the Public Health Centers in Padang, Indonesia: A Cross-Sectional Study

Background: The Indonesian Public Health Care (PHC) of Management Nutrition Therapy (MNT) guidelines describe that individual nutrition education is aimed to improve quality of MNT services. The guidelines were originally developed for non-communicable diseases (NCDs), not specially for type 2 diabetes mellitus (T2DM) purposes. The reluctance of patients with T2DM to attend individual nutrition education is a common public health care issue in Padang (Indonesia). Methods: The presented cross-sectional study aimed to determine the individual nutrition education needs among people with T2DM. A set questionnaire was distributed to 11 PHC selected from 11 districts in Padang and 179 patients with T2DM were recruited and interviewed. Results: Among the 179 patients with T2DM, 76.5% were females and housewives (49.2%), a slight majority (57.8%) were ≤58 years old and 45.9% had graduated from primary school. The highest numbers of patients with T2DM were in PHC Andalas (20.7%). Some 74.9% (134) of the people with T2DM routinely attended individual nutrition education classes for less than 30 min (60.3%). Patients with T2DM followed individual nutrition education at a PHC every 1–2 months (59.8%), and a majority of the individual nutrition education was given by a medical doctor (57.5%). In contrast, 42.3% of patients with T2DM did not attend individual nutrition education due to a lack of recommendation from a medical doctor and their reluctance (33.3%). Although a majority of patients with T2DM (62.6%) were satisfied with their individual nutrition education, (20.4% of patients with T2DM recommended the availability of booklets during individual nutrition education that can be read at home. Patients with T2DM needed individual nutrition education (88.8%) and the majority (25.1%) requested individual nutrition education topics about diabetes food recommendation. Even though patients with T2DM followed health professionals’ advice (78.2%), however, their HbA1c (76.5%) wasnot reduced. Patients with T2DM agreed that individual nutrition education can increase their knowledge (51.9%), unfortunately, they still have difficulty to control their blood glucose (5.6%). Conclusions: According to the patients with the T2DM perspective stated above, it is crucial to develop the tool kits and educate patients with T2DM following the Diabetes Nutrition Education (DNE) curriculum to improve glycemic control.

Effectiveness of interventions based on patient empowerment in the control of type 2 diabetes in sub-Saharan Africa: A review of randomized controlled trials

Background

It is estimated that 1.6 million deaths worldwide were directly caused by diabetes in 2016, and the burden of diabetes has been increasing rapidly in low- and middle-income countries. This study reviews existing interventions based on patient empowerment and their effectiveness in controlling diabetes in sub-Saharan Africa.

Method

PubMed, MEDLINE, EMBASE, CINAHL, Web of Science, PsycINFO and Global Health were searched through August 2018, for randomized controlled trials of educational interventions on adherence to the medication plan and lifestyle changes among adults aged 18 years and over with type 2 diabetes. Random-effects meta-analysis was used.

Results

Eleven publications from nine studies involving 2743 participants met the inclusion criteria. The duration of interventions with group education and individual education ranged from 3 to 12 months. For six studies comprising 1549 participants with meta-analysable data on glycaemic control (HbA1c), there were statistically significant differences between intervention and control groups: mean difference was -0.57 [95% confidence interval (CI) -0.75, -0.40] (P < .00001, I2 = 27%). Seven studies with meta-analysable data on blood pressure showed statistically significant differences between groups in favour of interventions. Subgroup analyses on glycaemic control showed that long-term interventions were more effective than short-term interventions and lifestyle interventions were more effective than diabetes self-management education.

Conclusion

This review supports the findings that interventions based on patient empowerment may improve glycaemia (HbA1c) and blood pressure in patients with diabetes. The long-term and lifestyle interventions appear to be the most effective interventions for glycaemic control.

Evaluation of global health capacity building initiatives in low-and middle-income countries: A systematic review

BACKGROUND

Low- and middle-income countries (LMICs) are in dire need to improve their health outcomes. Although Global Health Capacity Building (GHCB) initiatives are recommended approaches, they risk being ineffective in the absence of standardized evaluation methods. This study systematically reviews evaluation approaches for GHCB initiatives in LMICs.

METHODS

We searched the Medline (OVID), PubMed, Scopus, and Embase.com databases for studies reporting evaluation of a GHCB initiative in a LMIC from January 1, 2009 until August 15, 2019. To differentiate them from intervention, prevention, and awareness initiatives, included articles reported at least one approach to evaluate their learning modality. We excluded cross-sectional studies, reviews, and book chapters that only assessed the effect of interventions. Data identifying the learning modality, and evaluation method, level, time interval, and approach were extracted from articles as primary outcomes.

RESULTS

Of 8324 identified studies, 63 articles were eligible for analysis. Most studies stemmed from Africa and Asia (69.8%), were delivered and evaluated face-to-face (74.6% and 76.2%), mainly to professionals (57.1%) and community workers (20.6%). Although the use of online and blended modalities showed an increase over the past 4 years, only face-to-face initiatives were evaluated long-term beyond individual-level. GHCB evaluations in general lacked standardization especially regarding the tools.

CONCLUSION

This is an important resource for evaluating GHCB initiatives in LMICs. It synthesizes evaluation approaches, offers recommendations for improvement, and calls for the standardization of evaluations, especially for long-term and wider impact assessment of online and blended modalities.

Effect of a nutrition education programme on the metabolic syndrome in type 2 diabetes mellitus patients at a level 5 Hospital in Kenya: "a randomized controlled trial"

BACKGROUND

Type 2 diabetes mellitus (T2D), is a life-threatening condition of global public health concern. It worsens in the presence of the metabolic syndrome (MetS), a complex disorder characterized by co-occurrence of at least three of such factors as hypertension, obesity, dyslipidemia and insulin resistance. However, lifestyle interventions reduce the risk of both MetS and T2D, and nutrition education can empower individuals on the appropriate, lifestyle changes. The aim of the current study was to evaluate the effect of a nutrition education programme, with and without inclusion of peer to peer support, on MetS in T2D patients.

METHODS

This was a randomized controlled trial with two intervention groups and one control. One of the intervention groups involved a nutrition education programme with peer-to-peer support (NEP); the other involved only the education program, while the control received standard care. Each group had 51 participants. The nutrition education programme was conducted for 2 h per week for 8 weeks. In addition, the NEP had weekly peer-to-peer interactions for 8 weeks. All groups had follow-up sessions for 6 months. Data on MetS risk factors as well as food intake patterns and physical activity levels were taken at baseline and at different time points during the study. Analysis of Co-variance and regression were used in the analysis.

RESULTS

The MetS prevalence improved in the NEP (90 to 52%) and NE (86 to 69%), while it worsened in C (88 to 91%). There was improvement in the mean values of the anthropometric parameters in the NEP and NE which worsened in the control group. There was a general improvement in mean values of blood lipids, fasting blood glucose and HbA1c in all the groups, with NEP showing the greatest improvements, followed by NE, except for triglycerides and HDL where the control group had better improvement than the NE. Changes in the anthropometric and metabolic indicators mirrored the changes in food intake patterns and physical activity, where the greatest improvements occurred in the NEP.

CONCLUSIONS

Nutrition education with inclusion of peer to peer support was of clinical benefit in improving metabolic outcomes and reducing MetS in T2DM patients.

The Impact of a Community-Based Food Education Program on Nutrition-Related Knowledge in Middle-Aged and Older Patients with Type 2 Diabetes: Results of a Pilot Randomized Controlled Trial

The purpose of this study was to evaluate the impact of a community-based food education program on nutrition-related knowledge in middle-aged and older patients with type 2 diabetes (T2D). Participants (n = 36; 65.9 ± 6.0 years old) were recruited in primary health care to a 9-month community-based lifestyle intervention program for patients with T2D and randomly assigned to an exercise program (control group; n = 16) or an exercise program plus a food education program (experimental group; n = 20). Nutrition-related knowledge was assessed through a modified version of the General Nutrition Knowledge Questionnaire. The increase in total nutrition-related knowledge score and sources of nutrients area score was significantly higher in the experimental group compared to the control group. No significant changes in nutrition-related knowledge were found between groups in dietary recommendations and diet-disease relationship areas, although improvements were observed. This community-based food education program, with the use of easy to implement strategies (short-duration lectures and dual-task problem solving activities during exercise), had a positive and encouraging impact on nutrition-related knowledge in middle-aged and older patients with T2D.

An assessment of self-care knowledge among patients with diabetes mellitus

PURPOSES

This study aimed to (1) assess the level of diabetes self-care knowledge among patients with diabetes mellitus and (2) examine the relationship between patients' diabetes self-care knowledge and their demographic and medical characteristics.

METHODS

A cross-sectional design was used to implement the study. A convenience sample of 273 diabetic patients were recruited from five primary health-care centers in Amman- Jordan.

RESULTS

The overall level of knowledge of diabetes self-care in the total sample was moderate (58.28% (SD = 18.24)). The highest level of knowledge was meal planning (70.2%) followed by monitoring, causes of diabetes, foot care, symptoms and complication, diabetic medication, and the lowest level was exercise (42.5%). Furthermore, knowledge of diabetes self-care was found to be associated with age, educational status, diabetic medications and years with diabetes.

CONCLUSION

and Practice implications: The study findings emphasized that diabetic patients had a moderate level of knowledge and there were many of the learning needs for each area of knowledge. The health-care professional has an important role in developing the appropriate diabetes educational programs based on patients' learning needs and patients' characteristics. These programs that enhances knowledge on diabetes could be reduced or prevented diabetes-related complications.

Task-sharing interventions for cardiovascular risk reduction and lipid outcomes in low- and middle-income countries: A systematic review and meta-analysis

BACKGROUND

One of the potential strategies to improve health care delivery in understaffed low- and middle-income countries (LMICs) is task sharing, where specific tasks are transferred from more qualified health care cadre to a lesser trained cadre. Dyslipidemia is a major risk factor for cardiovascular disease but often it is not managed appropriately.

OBJECTIVE

We conducted a systematic review with the objective to identify and evaluate the effect of task sharing interventions on dyslipidemia in LMICs.

METHODS

Published studies (randomized controlled trials and observational studies) were identified via electronic databases such as PubMed, Embase, Cochrane Library, PsycINFO, and CINAHL. We searched the databases from inception to September 2016 and updated till 30 June 2017, using search terms related to task shifting, and cardiovascular disease prevention in LMICs. All eligible studies were summarized narratively, and potential studies were grouped for meta-analysis.

RESULTS

Although our search yielded 2938 records initially and another 1628 in the updated search, only 15 studies met the eligibility criteria. Most of the studies targeted lifestyle modification and care coordination by involving nurses or allied health workers. Eight randomized controlled trials were included in the meta-analysis. Task sharing intervention were effective in lowering low-density lipoprotein cholesterol (-6.90 mg/dL; 95% CI -11.81 to -1.99) and total cholesterol (-9.44 mg/dL; 95% CI -17.94 to -0.93) levels with modest effect size. However, there were no major differences in high-density lipoprotein cholesterol (-0.29 mg/dL; 95% CI -0.88 to 1.47) and triglycerides (-14.31 mg/dL; 95% CI -33.32 to 4.69). The overall quality of evidence based on Grading of Recommendations Assessment, Development and Evaluation was either "low" or "very low".

CONCLUSION

Available data are not adequate to make recommendations on the role of task sharing strategies for the management of dyslipidemia in LMICs. However, the studies conducted in LMICs demonstrate the potential use of this strategy especially in terms of reduction in low-density lipoprotein cholesterol and total cholesterol levels. Our review calls for the need of well-designed and large-scale studies to demonstrate the effect of task-sharing strategy on lipid management in LMICs.

Effectiveness of educational intervention based on psychological factors on achieving health outcomes in patients with type 2 diabetes

BACKGROUND

Managing type 2 diabetes (T2D) is assumed to be heavily dependent on patients' active participation in their own self-care behaviors including prescribed diets.

OBJECTIVES

The purpose of the present study was to investigate the effectiveness of educational intervention based on psychological factors on nutritional behaviors as well as levels of fasting blood sugar (FBS) and glycated hemoglobin (HbA1c) in patients with T2D referring to diabetes clinics and healthcare centers in the city of Izeh, Iran.

METHODS

A total number of 145 patients were recruited in this clinical trial and then randomly assigned to two groups of intervention (n = 73 individuals) and control (n = 72 individuals). After that, a researcher-made multi-part questionnaire including a demographic characteristics information form, a nutritional perceptions and beliefs questionnaire; a scale measuring fears, concerns, and discomforts associated with diabetic diet, as well as the valid and reliable Perceived Dietary Adherence Questionnaire were used to collect the required data before and 3 months after the completion of the educational intervention. To this end, the patients in the intervention group attended an educational program for eight sessions but the individuals in the control group only received routine services. Data analysis was also conducted using the SPSS Statistics (Version 18) and via descriptive and inferential statistics.

RESULTS

The findings revealed that the mean scores of the sub-groups of nutritional perceptions and beliefs (but not exaggerated ones) in the patients assigned to the intervention group were significantly higher than those in the control group after 3 months (p = 0.001). As well, the mean scores of the sub-groups of fears, concerns, and discomforts in patients as well as exaggerated beliefs witnessed a significant decrease in the intervention group compared to those in the control group (p = 0.001) 3 months after the educational intervention. Furthermore, the mean scores of adherence to a healthy diet in the intervention group had significantly increased compared to those in the control group. There was correspondingly a significant descending trend in the average levels of fasting blood sugar (FBS) and glycated hemoglobin (HbA1c) in the intervention group compared to those obtained in the control group (p = 0.001).

CONCLUSION

The results of this study shed light on the importance of the effectiveness of psychological factors on achieving health outcomes in patients with type 2 diabetes (T2D). Moreover, a new combination of diet-related psychological factors in patients with diabetes was introduced in the present study.Trial registration IRCT. IRCT20180308039008N1.
