Abstract

Background:

Central obesity is a major risk factor for cardiometabolic disorders including metabolic syndrome, type 2 diabetes, hypertension, and coronary artery disease. Regular physical activity plays a crucial role in reducing abdominal adiposity. Zumba, a dance-based aerobic exercise, is increasingly popular among women, but limited prospective data exist on its effect on central obesity markers.

Aim:

To assess the effect of regular Zumba exercise on BMI, waist circumference (WC), and waist–hip ratio (WHR) among females aged 18–40 years.

Methods:

A prospective cohort study was conducted among 100 females aged 18–40 years in Guwahati. Participants underwent supervised Zumba sessions (60 minutes, 3 days/week) for 12 weeks. Anthropometric parameters (BMI, WC, WHR) were measured at baseline and post-intervention. Paired t-test was used to compare pre- and post-intervention values. A p-value < 0.05 was considered statistically significant.

Results:

Significant reductions were observed after 12 weeks of Zumba. BMI decreased from 27.24 ± 2.27 kg/m² to 25.49 ± 2.39 kg/m² (p < 0.001). Waist circumference reduced from 88.13 ± 5.72 cm to 82.25 ± 5.71 cm (p < 0.001). WHR decreased from 0.89 ± 0.04 to 0.85 ± 0.05 (p < 0.001).

Conclusion:

Regular Zumba exercise significantly reduces central obesity markers and may serve as an effective, enjoyable, and sustainable strategy for obesity management among young and middle-aged women.
