Abstract

The incidence of hypertension in Indonesia is increasing, affecting not only the elderly population but also young adults aged 18–39 years. Prehypertension is an early indicator of hypertension; however, the application of fruit-based interventions remains limited. Bananas, particularly their peels, are abundant in nutrients and bioactive compounds that may mitigate hypertension. This study aimed to assess the impact of banana peel smoothing on blood pressure in individuals with prehypertension. A quasi-experimental pre-post-test design was employed. Thirty-two participants were screened and equally divided into two groups: one receiving banana fruit smoothies, and the other receiving banana peel smoothies. The study was conducted from February to March 2024 at the Faculty of Agriculture, Siliwangi University, Tasikmalaya, West Java. Blood pressure measurements were obtained before and after the intervention, and the data were analyzed using a paired t-test. Both banana fruit and banana peel smoothies significantly reduced blood pressure (p= 0,000) in both interventions. In conclusion, banana peel smoothies exhibited greater efficacy in lowering blood pressure in prehypertensive individuals than banana fruit. Banana peel smoothies represent an effective intervention for reducing blood pressure in prehypertensive individuals, offering a promising and nutrient-rich approach for hypertension management.

Abstract

This study examined the individual and combined effects of tomato juice and increased daily walking on blood pressure in prehypertensive adults. A total of 34 sedentary participants aged 19–36 years were randomly assigned to four groups: control, tomato juice, walking, and a combination of both. The intervention lasted for 14 days, during which participants consumed 200 ml of unsalted tomato juice and/or increased their steps by a minimum of 5,000 steps per day (on average), tracked using health (iOS) or Google Fit (Android). Blood pressure was measured before and after the intervention and analyzed using paired t-tests (p<0,05). All intervention groups showed a reduction in systolic blood pressure, with the combination group showing the most significant decrease—from 128,75±4,20 to 110,50±6,05 mmHg (p=0,000) for systolic and from 82,50±8,40 to 74,74±3,92 mmHg (p=0,033) for diastolic pressure. A significant correlation between body mass index and blood pressure reduction was also observed, suggesting that body weight may influence the effectiveness of these lifestyle interventions.

Abstract

Introduction: Coronary heart disease (CHD) is a leading cause of mortality among the elderly. Promoting healthy lifestyles through balanced diets and regular physical activity is essential for prevention programs. However, the availability of standardized and validated instruments to measure knowledge of healthy lifestyles among elderly individuals is still limited, particularly in Indonesia. This study aimed to develop and validate a knowledge questionnaire focusing on diet and physical activity for elderly individuals at risk of CVD. Methods: A mixed-method validation was conducted, involving qualitative and quantitative approaches. First, content validity was assessed by experts in community nutrition, clinical nutrition, and sport nutrition (n = 8) using the Content Validity Index (CVI) and multi-rates Kappa statistics. Second, face validity was tested with elderly participants (n = 10) to ensure clarity and comprehension. Finally, item validity and reliability testing were examined with elderly participants (n = 30) using the Pearson correlation test between item-total score and Cronbach’s Alpha to determine internal consistency. Results: The I-CVI values for all items ranged from 0,75 to 1,00, and Kappa statistics from 0,72 to 1,00, indicating good to excellent agreement among experts. Face validation confirmed that most items were relevant and understandable, with brief wording adjustments required for clarity. The Cronbach’s alpha of 0,742 reflected good internal consistency. Overall, the validation process demonstrated that 19 of 28 items met the statistical criteria. Conclusion: The healthy lifestyle knowledge questionnaire demonstrated strong validity and reliability in assessing knowledge among elderly individuals at risk of CHD. This instrument is practical and applicable for supporting health promotion and prevention programs focusing on diet and physical activity.
