Evidence Synthesis

Diabetes is regarded as one of the most problematic and major health concerns that has become prevalent across the globe. According to Kam et al. (2016), in 2012, diabetes resulted in the deaths of 1.5 million people throughout the world. Given its prevalence and devastating impacts, effective prevention and management of diabetes has become a major issue, especially among high-risk individuals/populations. Based on existing findings in the public health sector, dietary and lifestyle changes have been identified as the most suitable prevention and management techniques of diabetes. This study focuses on examining whether an intervention consisting of a traditional, organic, and all-natural diet of locally grown/produced foods plus exercise is more effective in addressing the body's issues in creating or absorbing insulin than insulin injections. In this regard, the researcher has identified relevant studies that will be synthesized based on their relevance, rigor, and level of evidence in relation to the phenomenon under investigation.

Approach to Synthesizing Evidence

For this study, the researcher utilized a mixed methods approach for synthesizing evidence. The mixed-methods approach involved conducting systematic reviews of complex, behavioral change interventions, which are regarded as effective measures for summarizing evidence based on their relevance and effectiveness to the issue under investigation (Leeman et al., 2011). When synthesizing the evidence, the researcher identified some variables of interest that guided the process. Some of these variables of interest include dietary and exercise interventions for Type II diabetes, creation and/or absorption of insulin, and insulin injections. These variables of interest were identified based on the PICOT question and the purpose/significance of the study.

Narrative Descriptions of Studies

Oftedal, Bru & Karlsen (2011) conducted a study to examine motivation for self-management techniques of Type II diabetes among adults suffering from this condition. The study was carried out on the premise that many diabetic patients find it difficult to comply with self-management regimes because of the behavioral demands and challenges associated with them. The researchers found that diet management and exercise management regimes are crucial addressing the body's issues in creation or absorption of insulin. However, the effectiveness of these self-management techniques requires both intrinsic and extrinsic motivation factors. The researchers employed a cross-sectional study design consisting a postal questionnaire that was administered to 427 adults with Type II diabetes. The study provides Level II evidence, which is high-quality evidence because it provides an indicator of patients' experiences in diet and exercise management. The study is significant for this research because it not only indicates the role of diet and exercise in management of Type II diabetes but also indicators factors that affect a patient's compliance with such regimes.

Aguiar et al. (2014) conducted a study to examine the effectiveness of several interventions such as diet, aerobic and resistance training in the prevention of Type II diabetes. The research was carried out on the premise that existing recommendations for preventing this condition are centered on changes in diet and exercise behaviors include aerobic and resistance training. To achieve the goals of the study, the researchers employed a systematic review and meta-analysis that reviewed the effectiveness of multi-component lifestyle interventions in prevention and management of the condition. This systematic, meta-analysis research provides Level I evidence, which demonstrate that multi-component interventions that include diet and exercise changes help in effective prevention and management of Type II diabetes. This study is significant for this current research because it demonstrates the role of multi-component interventions in preventing and/or managing Type II diabetes. The significance is based on the role multi-component interventions play in relation to weight loss, enhancing glucose tolerance and damaged fasting glucose, and improving dietary and exercise results.
