ABSTRACT


Background: Nurses play a crucial role in supporting patients at risk for diabetes or prediabetes in changing their lifestyles and halting the progression of prediabetes to diabetes. Objective: This literature review aims to explain nursing interventions for preventing diabetes in prediabetes or high-risk individuals. Methods: Four databases were utilised to look for pertinent peer-reviewed papers written in English: Scopus, PubMed, CINAHL, and Web of Science. Studies examining nursing interventions in diabetes prevention in adults older than 18 years at risk of diabetes or prediabetes met the inclusion criteria for this review. The literature search was restricted to open- access publications published between 2019 and 2024. The instrument used in the article screening stage uses screening software, namely Rayyan. Results: A total of 1,005 articles, all retrieved from four databases, were included in the study. Nineteen publications that met the inclusion criteria were included in this review. Based on the results of a synthesis analysis of 19 literature reviews, nursing interventions to prevent diabetes in individuals at risk of prediabetes include prediabetes screening and diabetes risk (3 articles), lifestyle intervention (9 articles), diabetes prevention education (5 articles), and stress management (3 articles). Nursing interventions have proven effective in improving diabetes risk factors such as diet, physical activity, reducing HbA1c, body weight, BMI, fasting blood sugar, waist circumference, stress, anxiety, and quality of life, and preventing the development of type 2 diabetes. Conclusion: Nursing interventions are successful in reducing risk factors for type 2 diabetes in those with prediabetes or those at risk.

INTRODUCTION

The prevalence of diabetes mellitus (DM), a chronic illness, has dramatically increased globally during the past three decades (WHO, 2024). It is projected that the number of adults (20–79 years old) with diabetes will rise from 537 million in 2021 to 643 million in 2030 and 783 million in 2045 (International Diabetes Federation, 2021). Prediabetes is one disorder that can accelerate the onset of DM (Venkataramani et al., 2019). Increased blood glucose levels that fall short of the standard for a diabetes diagnosis are indicative of prediabetes, a condition that raises the risk of getting the disease (Rooney et al., 2023). An estimated 97.6 million adults over the age of 18 or older have prediabetes (CDC, 2024). Individuals with prediabetes face up to a 50% risk of progressing to diabetes mellitus (DM) within five years (Rooney et al., 2023).


The Diabetes Prevention Program (DPP) helps adult and adolescent individuals at risk of diabetes avoid DM through lifestyle modification interventions (Peña et al., 2022). Diabetes Mellitus negatively affects individuals by reducing life expectancy, increasing the risk of illness, and diminishing overall quality of life (Amelia & Kurniawati, 2018). Randomised controlled trial studies on DPP have demonstrated the efficacy of basic lifestyle interventions in preventing diabetes mellitus (DM) in adults with prediabetes or type 2 diabetes who are at high risk of developing the disease (Ford et al., 2019; Vargas-Ortiz et al., 2020). It is strongly recommended in clinical practice to implement lifestyle prevention treatments; nevertheless, most persons with prediabetes remain untreated because healthcare professionals lack the necessary expertise, time, and resources (Abbate et al., 2021).


Nurses are one of the health service providers whose role is to provide nursing care to individuals with prediabetes. This can be done by nurses by implementing evidence-based interventions to overcome risk factors for the development of prediabetes into DM (Moore-Harper, Shubrook & Clavo-Hall, 2023). Nursing professionals can help people with prediabetes or who are at risk of diabetes to reduce risk factors and change their diets to help prevent type 2 diabetes based on research findings (O’Flynn, 2022). Nurses can help individuals with prediabetes improve their diabetes prevention behaviours through screening, diabetes prevention education, promotion of dietary and lifestyle modifications, stress management, and training (Böhme et al., 2020; Woods- Giscombe et al., 2019). They can also involve family members and use digital health technology to support nursing interventions (Andreae et al., 2024; Nguyen et al., 2024).


A review of the literature has been done on interventions to prevent type 2 diabetes mellitus in people with prediabetes. However, it only addresses pharmacological, dietary, and lifestyle changes and does not focus on nursing interventions (Thipsawat, 2023). A study shows that primary care providers, including nurses, rarely provide screenings and counselling to individuals with prediabetes regarding lifestyle modifications that are beneficial for preventing DM. This is caused by the lack of knowledge among nurses regarding evidence-based lifestyle modification interventions for preventing DM (Kandula et al., 2018). This shows that there is a significant knowledge gap among health service providers, especially nurses, regarding prediabetes management, which means nurses do not have the opportunity to carry out effective nursing interventions to help individuals with prediabetes prevent diabetes. Therefore, a literature review is needed that can increase nurses' knowledge regarding effective nursing interventions to prevent diabetes in individuals with prediabetes. The literature review aims to explain nursing interventions for preventing diabetes in prediabetes or high-risk individuals.


METHODOLOGY

Design of Research

The design of this research is a literature review. The research question in this study is: What nursing interventions are carried out by nurses to help prevent DM in individuals at risk of diabetes or prediabetes? To identify research questions, researchers used the PICO shown in Table 1.

Search Methods

Scopus, PubMed, CINAHL, and Web of Science are the four databases searched for pertinent peer- reviewed articles published in English as part of a literature review methodology. The chosen keywords “nursing intervention” OR “nurse-led" AND “diabetes prevention" AND "diabetes risk" OR "prediabetes" was paired with the Boolean operators "AND" and "OR" in the literature search, which was restricted to open access papers from 2019 to 2024. The PRISMA flow diagram is used to identify, screen, and finalise the selection of articles to be reviewed according to the inclusion criteria (Page et al., 2021).


Selection Methods

A search of the literature was conducted, and the articles that would be reviewed were found. Two authors (OSN and FE), who are also reviewers, screened titles and abstracts that met the inclusion criteria. Conflicts were resolved through discussion between three reviewers (OSN, FE, and YSD). The full text was reviewed by both reviewers (OSN and FE), and disagreements were resolved through discussion between the three reviewers (OSN, FE and YSD). The final 19 articles were included in this review.


Data Extraction

The data extraction process for articles that meet the inclusion criteria is carried out by the author (OSN) independently using a data extraction format. Data extraction components include authors, publication years, methods (research design, subjects, data analysis), nursing interventions, and research results.


Criteria for Research

The inclusion criteria of this review are 1) studies that examined the nursing intervention of diabetes prevention in individuals at risk of diabetes or prediabetes; 2) all research designs, but they must be original research, not systematic reviews or other types of reviews. 3) Adults over the age of 18 who are at risk of developing diabetes or prediabetes; 4) The goal of diabetes prevention nursing interventions is to prevent the onset of diabetes by addressing risk factors for the disease.

Exclusion criteria include individuals with type 1 diabetes mellitus, type 2 diabetes mellitus, and gestational diabetes; articles that are not open access; books, documents, reviews, conference proceedings, theses, or dissertations.

RESULTS

The authors obtained 1,005 articles from four databases: CINAHL (300 articles), PubMed (606 articles), Scopus (49 articles), and Web of Science (50 articles). Some articles were identified as duplicates by Rayyan (n = 325), ineligible by the automation tool (n = 214), and manually removed by the researcher because they did not meet the inclusion criteria (n = 242). The article filtering process used Rayyan, resulting in 224 articles that passed the screening stage. A total of nineteen articles that met the inclusion criteria were reviewed.

Based on the analysis and synthesis in Table 3, it shows that from the 19 literature reviews, three studies discuss nursing interventions for individuals at risk of diabetes or prediabetes with prediabetes screening and diabetes risk, nine studies with lifestyle interventions, five studies with diabetes prevention education and three studies with stress management.


DISCUSSION

The research aims to identify nursing interventions that can be implemented to prevent diabetes in individuals at risk of prediabetes. The review highlights four types of nursing interventions that support individuals at risk of prediabetes in preventing developing type 2 diabetes mellitus: prediabetes screening, lifestyle interventions, diabetes prevention education, and stress management. Prediabetes screening and diabetes risk. Nurses have an important role in screening individuals for prediabetes and diabetes risk (Arnardóttir et al., 2023; Böhme et al., 2020). The Finnish Diabetes Risk Score (FINDRISC) is a screening tool that nurses can use in primary care to identify patients who are not yet diagnosed with diabetes and those who are at risk for the disease. To determine prediabetes with the best degree of sensitivity and specificity, use a FINDRISC cut point of ≥11 (Arnardóttir et al., 2023). Nurses can also conduct screenings using the Diabetes Risk Questionnaire (Woods-Giscombe et al., 2019).

Lifestyle Interventions

Large, randomised trials have demonstrated the effectiveness of lifestyle interventions in delaying the onset of type 2 diabetes mellitus (Amer et al., 2020; Ford et al., 2019; Liu et al., 2022; Sampson et al., 2020). Nurses are expected to possess adequate competence in implementing lifestyle interventions, including nutrition and physical activity, through inter-professional collaboration with nutritionists, psychologists, and general practitioners. Involving families is also essential to developing comprehensive care strategies that support individuals with prediabetes in making lifestyle changes to prevent diabetes (Iglesies-Grau et al., 2023; Vargas-Ortiz et al., 2020).

Nutrients

Nurses can implement dietary interventions by offering support, motivation, and counselling on a healthy, culturally appropriate diet, as well as assisting individuals with prediabetes in reducing fat intake (to less than 30% of total energy) and total calorie consumption (Ford et al., 2019). Dietary interventions provided by nurses include a low-calorie diet, a diet with a low glycaemic index, high fibre (vegetables and fruit), whole grains, nuts, fish as a source of protein, and olive oil as a source of fat because it has been proven to reduce the risk of developing type 2 DM in individuals with prediabetes. Nurses also teach how to read food labels (Bean et al., 2021; Ford et al., 2019; Iglesies-Grau et al., 2023). Nurses can provide nutritional interventions using teleconsultation and group SMS 4–5 times per week (Abbate et al., 2021; Fauzi et al., 2023).

Physical Activity

Nurses can provide advice and teach concrete and relevant skills to assist at-risk individuals in increasing physical activity (Abbate et al., 2021; Sampson et al., 2020). People with prediabetes benefit from 150 minutes a week of moderate-intensity physical activity. A randomised, controlled trial study showed that at least 150 minutes of moderate-intensity physical activity per week were proven to be effective in reducing fasting blood sugar, BMI, and diastolic blood pressure (Amer et al., 2020; Shamizadeh et al., 2019).

Diabetes Prevention Education

Diabetes prevention education is an intervention nurses can implement to help individuals with prediabetes or at risk of diabetes adopt healthier lifestyle behaviours (Woods-Giscombe et al., 2019). Key topics include prediabetes and diabetes concepts, insulin resistance, diet, physical activity, and lifestyle changes such as stress reduction and smoking cessation (Iglesies-Grau et al., 2023; Koirala et al., 2024).

Stress Management

Nurses have an important role in helping individuals at risk of diabetes or prediabetes manage stress. Based on many evaluations of the research, glycaemic control measures, such as glycosylated haemoglobin (HbA1c) levels, can be somewhat improved in individuals with diabetes and prediabetes by treatments that target stress-reducing variables (Woods-Giscombe et al., 2019; Xia et al., 2022). Stress management interventions that can be carried out by nurses are mindfulness-based stress reduction (MBSR) interventions and cognitive behavioural therapy (Washirasaksiri et al., 2024; Woods-Giscombe et al., 2019; Xia et al., 2022).

Research Implications

The results of the literature review on nursing interventions for preventing diabetes in individuals with prediabetes have implications for nursing practice, policy, and future research.

Nursing Practice

Nursing interventions should prioritise encouraging lifestyle changes, including diet, physical activity, and stress management (Iglesias-Grau et al., 2023; Vargas-Ortiz et al., 2020). Nurses play a crucial role as educators, providing education and counselling on diabetes prevention for individuals with prediabetes (Amer et al., 2020; Ford et al., 2019; Liu et al., 2022; Sampson et al., 2020).

Policy

Establishing clear standard guidelines for prediabetes screening in primary health care can improve early detection and intervention to prevent the development of type 2 DM in individuals with prediabetes (Arnardóttir et al., 2023; Böhme et al., 2020).

Research

More research is required to determine the most effective components of nursing interventions and their long-term effects on the development of type 2 diabetes mellitus (DM) in larger populations with prediabetes.

Limitation

The limitation of this research is that not all the articles reviewed used randomised controlled trials, and the intervention focusses only on adults. Future research will be able to develop or examine nursing interventions to prevent diabetes in children and adolescents, considering that the prevalence of type 2 DM in adolescents has increased in the last two decades.


CONCLUSION

Nursing interventions that include prediabetes screening, lifestyle modification, diabetes prevention education, and stress management are effective in preventing the development of diabetes in individuals with prediabetes or who are at risk for developing diabetes. This study emphasises the important role of nurses in preventing the onset of type 2 diabetes in individuals with prediabetes or at risk for diabetes. By addressing knowledge gaps in evidence-based nursing practice, this review highlights effective interventions, including lifestyle modification, prediabetes screening, stress management, and diabetes prevention education. These interventions improve clinical outcomes and empower health professionals to provide holistic and sustainable care, ultimately reducing the global burden of diabetes.

Conflict of Interest

There is no conflict of interest.
