Qualitative Study
Study Protocol of ” Worth the Walk”: a randomized controlled trial of a stroke risk reduction walking intervention among racial /ethnic minority older adults with hypertension in community senior centers by Kwon, et al., (2015).
Background of the study
Stroke has become one of the leading causes of high mortality rates in the United States. Stroke is also responsible for disabling most of the minority seniors. Approximately 30% of the strokes are related to lack of physical activity, but most of the older generations in most of the ethnic groups in the United States tend to participate most in physical exercise.

Significance of the study
Most of the African American, Chinese, Korean, and Latino seniors with hypertension are the most affected groups by stroke. As a result, the cost of health among the mentioned groups tends to be high, and yet the mortality rate continues to be high every year. Walking among the seniors can increase their physical activity, which can, in turn, reduce the risks of stroke, especially among those seniors suffering from hypertension.
The purpose of the study
To conduct a randomized controlled trial to assess the effects of a culturally designed walking intervention that is community-based to decrease the risk of stroke by increasing the rate of physical exercise among Latino, African American, Korean and Chinese seniors suffering from hypertension.
Research question
Does walking intervention reduce the risk of stroke among the racial/ethnic older adults with hypertension in senior community centers?
Research method
The researchers enrolled the minority seniors of the targeted groups at senior centers and used data collection with complete baseline. The selected groups were then assigned to receive the walking intervention randomly. The sample size was 120, which was obtained after a full 90 days follow up intervention. The researchers’ assigned trained case managers to conduct qualitative methods to answer the research questions. They implemented the intervention sessions two times a week for four consecutive weeks to the targeted intervention group. The measures for primary outcome included the stroke knowledge, mean steps per day for more than seven days, and self-efficacy for reducing the risk of stroke. The measures for exploratory and secondary measures include health-seeking, health-related quality of life, and biological markers for health. The researchers collected the outcome data from participants in the wait-list control and intervention participants three months after complete baseline data collection (Chiu, Bergeron,Williams, Bray, Sutherland & Krauss, 2015). The outcomes were then compared between the two groups using randomized trials data analytic methods. The facilitators and the barrios to the successful implementation of worth the walk were also assessed. The researchers did not indicate the weakness of the available studies and also did not include a conceptual framework in their research.
Qualitative Study
Results of the study
The randomized controlled trial demonstrated considerable improvements in knowledge about stroke and body exercise in the intervention group as compared to the control group (Chiu, et al. 2015). Nurses should consider the intervention as the primary prevention strategy for stroke among seniors in various minority ethnic or racial groups in the United States.
The findings of the study suggest that nursing education should highly consider training the nurses about physical exercise and implement the worth a walk intervention to improve patient outcome.
Ethical considerations
Patient confidentiality was considered in the study. Information regarding individual participants in the study was well handled to avoid its leakage to unauthorized persons. Also, the study was approved by the Institutional Review Board.
Conclusion
The risk of stroke is highly increased with the reduction of physical exercise, especially among the seniors in the minority ethnic or racial groups in the United States. Nursing practice should emphasize increased physical activity among the minority groups, especially the seniors with hypertension, to reduce the risks of stroke. It is the responsibility of the nurses to create awareness on the benefits of body exercise in minimizing the stroke cases, which can, in turn, reduce the treatment costs and reduce the mortality rates.
Quantitative Study
Comparison of the Dash (Dietary Approaches to Stop Hypertension) diet and a higher-fat Dash diet on blood pressure and lipids and lipoproteins: a randomized controlled trial, by Chiu, S., Bergeron, N., Williams, P. T., Bray, G. A., Sutherland, B., & Krauss, R. M. (2015).
Background of the study
The Dietary Approaches to prevent and stop hypertension include incorporation of a dietary pattern that is high in vegetables, fruits, and low in fats, especially dairy foods. The Dash enhances low-density lipoprotein, lowering of high blood pressure and cholesterol, that is high-density lipoprotein.
Significance of the study
Hypertension is a condition that is a highly experienced condition, especially among the aging generations. The leading causes of hypertension are reduced physical exercise and poor dieting. Hypertension increases health costs and also leads to high mortality rates, especially among the senior groups in society.
Purpose of the study
The main objective of the study was to examine the effects of substitution of full-fat with low-fat dairy food products in the DASH diet with a corresponding increase in fat and a decrease in the intake of sugar on plasma lipids, lipoproteins and blood pressure.
Qualitative Study
Research question
Do the DASH and HF-DASH diet lower high-density lipoprotein cholesterol, low-density lipoprotein, and high blood pressure?
Research methods
The researchers used a sample size of three health persons to conduct a randomized crossover trial based on three periods. The individuals consumed a standard Dash diet, a control diet, a lower carbohydrate modification of Dah diet, and a high-fat diet for three weeks each which was separated by two weeks’ periods for washouts (Kwon, et al. 2015). The researchers then conducted laboratory measurements that included the concentration of lipoprotein particles determined by the mobility of ions, which was established at the end of each experimental diet (Kwon, et al. 2015). The researchers used both dependent and independent variables. The dependent variable was high blood pressure, and the DASH and HF-DASH diet were the independent variables that were presented after the tests (Kwon, et al. 2015). The variables were shown on a graph with the high blood pressure being on the y-axes and the DASH and HF -DASH diets being on the x-axes. Each of the researchers analyzed the data using the Statistical Packages for Social Sciences and compared their results to eliminate the chances of personal bias and ensure the accuracy of results.
Results of the study
The participants of the study finished the three dietary periods. The HF-DASH and DASH diets profoundly reduced blood pressure compared to the control diet. There was a reduction in the concentration of medium and large very-low-density lipoprotein particles and triglycerides (Kwon, et al. 2015). The HF-DASH diet also increased the peak particle diameter of LDL and decreased the HDL cholesterol, LDL cholesterol, apolipoprotein A-I, large LDL particles Intermediate density lipoprotein and the width of LDL peak compared with the control diet. The researchers did not mention any limitations of the study.
Qualitative Study
Ethical considerations
The Institution Review Board approved the study. Also, the confidentiality of the participants in the study was highly maintained.
Conclusion
The DAS diet significantly lowered blood pressure to the same extent as the HF- DASH diet and also reduced the concentration of VLDL and plasma triglyceride without increasing the cholesterol. The findings of the study can help improve nursing practice in managing hypertension. Nurses should create awareness among patients and the community at large about the DASH and HF-DASH diet to help reduce the mortality rates and the costs of treatments.
