Abstract

Diabetes mellitus (DM) is a chronic metabolic disorder characterized by hyperglycemia due to inadequate insulin production or impaired insulin utilization. In Indonesia, the prevalence of DM reaches 11.7% in adults, with a significant burden in Batam, particularly at Puskesmas Sei Langkai. This study aims to determine the relationship between physical activity and nutritional status with blood glucose levels in type 2 DM patients aged 45–69 years. This is an observational analytical study with a cross-sectional design conducted in October 2025, involving 120 respondents selected purposively. Physical activity was measured using a short IPAQ questionnaire and converted to MET-minutes/week, nutritional status was measured using Body Mass Index (BMI), and random blood glucose levels were measured using a glucometer. Data analysis was performed using the Spearman correlation test. The results showed that the majority of respondents were aged 45–59 years (76.7%), female (70.8%), had a high school education (65.8%), were unemployed (67.5%), and had suffered from DM for 1–5 years (62.5%). Most had moderate physical activity (65.8%) and normal nutritional status (77.5%), but 53.3% had uncontrolled blood glucose levels. Analysis showed a significant negative relationship between physical activity and blood glucose levels (r = -0.305, p = 0.001), while nutritional status showed no significant relationship (r = 0.159, p = 0.083). These findings confirm that physical activity plays an important role in blood glucose control, while nutritional status alone is not the main determining factor. DM management should include regular physical activity, a balanced diet, adherence to therapy, and routine glucose monitoring.

Abstract

Background: Obesity is strongly linked to elevate leptin levels and oxidative stress, both of which contribute to the development of various metabolic disorders. Leptin, a hormone that regulates metabolism and appetite, becomes less effective in obese individuals due to leptin resistance, thereby exacerbating metabolic dysfunction.Objective: This study aims to evaluate the effect of red dragon fruit (hylocereus polyrhizus) juice on leptin levels in Sparague Dawley rats using an overweight model.Method: This experimental study used a pre-post test control group design and involved six groups of rats (n=6 per group), including a normal group, a negative control group, a positive control group (orlistat), and three treatment groups receiving different doses of red dragon fruit juice (3.5 g, 7 g, and 10.5 g per 200 g body weight). The intervention was carried out for 14 days following a 14- day induction of obesity using a high-fat and high-carbohydrate diet. Leptin levels were measured before and after the intervention.  Results: The results showed that administration of red dragon fruit juice significantly reduced leptin levels (p<0,001) in all treatment groups. The greatest reduction was observed in the group receiving the 10.5 g dose, with an average decrease of 75.03%, which was nearly equivalent to the orlistat group that reduced leptin levels by 79.93%.Conclusion: Red dragon fruit juice has the potential to serve as a non-pharmacological agent in reducing leptin levels and oxidative stress under obesity conditions, with an effectiveness approaching that of orlistat.
