Influence of 24-week yoga intervention on cardiovascular risk factors and inflammatory markers in type 2 diabetes

Abstract

Background and Aims: Persistent hyperglycemia, dyslipidemia, inflammation, and oxidative stress are important in cardiovascular risk in type-2 diabetes mellitus (DM). To evaluate the effect of 24-week yoga intervention on anthropometry and biochemical markers in DM patients, we performed a study. Methods: A hospital-based prospective randomized study in 104 participants with DM divided into control (n = 52) and intervention (n = 52) groups was performed. Patients in the intervention group performed 40 min of multifaceted individualized yoga exercises 5 days/week for 24 weeks. Anthropometric measurements and biochemical analysis were performed at baseline and after 24 weeks in both groups. Descriptive statistics are reported. Results: Baseline characteristics were similar in both groups. At 24 weeks, participants in the intervention versus controls had lower body mass index (25.6 ± 2.9 vs. 28.0 ± 3.2 kg/m2), waist–hip ratio (0.94 ± 0.06 vs. 0.99 ± 0.05), systolic blood pressure (121.2 ± 11.7 vs. 139.3 ± 19.1 mmHg), fasting glucose (142.7 ± 45.3 vs. 175.7 ± 45.4 mg/dL), glycated hemoglobin (7.2 ± 1.8 vs. 9.4 ± 1.9%), low-density lipoprotein cholesterol (167.5 ± 38.1 vs. 192.2 ± 51.4 mg/dL), nonhigh-density lipoprotein cholesterol (136.8 ± 35.3 vs. 158.6 ± 47.2 mg/dL), interleukin-6 (32.0 ± 21.5 vs. 43.5 ± 34.3 pg/mL), and high-sensitivity C-reactive protein (5.1 ± 3.7 vs. 9.5 ± 15.6 mg/L) (P ≤ 0.05). In the intervention group, higher levels of high-density lipoprotein cholesterol (49.2 ± 15.0 vs. 40.4 ± 7.2 mg/dL) and serum total antioxidants (1.9 ± 0.4 vs. 1.4 ± 0.4 mmol/L) were observed (P < 0.001). Conclusion: A short-term yoga intervention led to reduced glycemia, dyslipidemia, and inflammatory markers and increased antioxidant status in patients with type-2 DM.
