Abstract

BACKGROUND:

Abdominal obesity is a major risk factor for morbidity and mortality. The aim of this study was to investigate the effect of yoga on waist circumference and other anthropometric and self-reported variables in women with abdominal obesity.

METHODS:

60 women with abdominal obesity (waist circumference ≥ 88 cm; body-mass index [BMI] ≥ 25) were randomly allocated in a 2:1 ratio to either a 12-week yoga intervention (n = 40) or a waiting list (n = 20). The waist circumference was the primary endpoint. Secondary (exploratory) endpoints included the waist/hip ratio, body weight, BMI, body fat percentage, body muscle mass percentage, blood pressure, health-related quality of life, self-esteem, subjective stress, body awareness, and body responsiveness, and the safety of the intervention. The persons assessing the outcomes were blinded to the group to which the patients belonged.

RESULTS:

The patients in the yoga group participated in a mean of 30.2±9.2 (maximum, 42) hours of supervised yoga practice. Their abdominal circum - ference was significantly reduced in comparison to the participants on the waiting list, with an intergroup difference of -3.8 cm (95% confidence interval [-6.1; -1,.5]; p = 0.001). There were further, moderate intergroup differences in the waist/hip ratio, body weight, BMI, body fat percentage, body muscle mass percentage, mental and physical well-being, self-esteem, subjective stress, body awareness, and trust in bodily sensations (all p<0.05). There were no serious adverse events. None of the participants embarked on a low-calorie diet while participating in the study.

CONCLUSION:

The 12-week yoga intervention had moderately strong positive effects on anthropometric and self-reported variables in women with abdominal obesity. Yoga is safe in this population and can be recommended as a technique for combating abdominal obesity in women.
