Yoga practice is associated with attenuated weight gain in healthy, middle-aged men and women
Yoga is promoted or weight maintenance, but there is little evidence of its efficacy.
To examine whether yoga practice is associated with lower mean 10-year weight gain after age 45.
Participants included 15,550 adults, aged 53 to 57 years, recruited to the Vitamin and Lifestyle (VITAL) cohort study between 2000 and 2002.
Physical activity (including yoga) during the past 10 years, diet, height, and weight at recruitment and at ages 30 and 45. All measures were based on self-reporting, and past weight was retrospectively ascertained.
Multiple regression analyses were used to examined covariate-adjusted associations between yoga practice and weight change from age 45 to recruitment, and polychotomous logistic regression was used to examine associations of yoga practice with the relative odds of weight maintenance (within 5%) and weight loss (> 5%) compared to weight gain.
Yoga practice for four or more years was associated with a 3.1-lb lower weight gain among normal weight (BMI < 25) participants [9.5 lbs versus 12.6 Ibs] and an 18.5-lb lower weight gain among overweight participants [-5.0 lbs versus 13.5 Ibs] (both P for trend <.001). Among overweight individuals, 4+ years of yoga practice was associated with a relative odds of 1.85 (95% confidence interval [CI] 0.63-5.42) for weight maintenance (within 5%) and 3.88 (95% Cl 1.30-9.88) for weight loss (> 5%) compared to weight gain (P for trend .026 and .003, respectively).
Regular yoga practice was associated with attenuated weight gain, most strongly among individuals who were overweight. Although causal inference from this observational study is not possible, results are consistent with the hypothesis that regular yoga practice can benefit individuals who wish to maintain or lose weight.

- "Compared to runners and sedentary individuals, yoga practitioners were significantly less likely to eat meat (Satin et al., 2014). Healthy dietary behaviors have been related to frequency of yoga practice (Kristal et al., 2005; Ross et al., 2012) and longer practice duration (Kristal et al., 2005). In the national survey of Iyengar practitioners, daily fruit and vegetable servings were positively associated with frequency of home practice and gentle and standing yoga postures. "

ABSTRACT: Yoga has become increasingly popular in the US and around the world, yet because most yoga research is conducted as clinical trials or experiments, little is known about the characteristics and correlates of people who independently choose to practice yoga. We conducted a systematic review of this issue, identifying 55 studies and categorizing correlates of yoga practice into sociodemographics, psychosocial characteristics, and mental and physical well-being. Yoga use is greatest among women and those with higher socioeconomic status and appears favorably related to psychosocial factors such as coping and mindfulness. Yoga practice often relates to better subjective health and health behaviors but also with more distress and physical impairment. However, evidence is sparse and methodological limitations preclude drawing causal inferences. Nationally representative studies have minimally assessed yoga while studies with strong assessment of yoga practice (e.g., type, dose) are generally conducted with convenience samples. Almost all studies reviewed are cross-sectional and few control for potential confounding variables. We provide recommendations for future research to better understand the correlates of yoga practice.

- "We use a multi-method approach to collect cost data at 6, 12, 26, 40, and 52 weeks. Since our interventions may influence other common comorbidities of cLBP (e.g., depression  and obesity ), we measure total medical utilization, not only back-related utilization. Direct medical costs are measured, which consist of the cost of i) implementing the interventions themselves and ii) ongoing medical utilization during and after the intervention. "

ABSTRACT: Chronic low back pain causes substantial morbidity and cost to society while disproportionately impacting low-income and minority adults. Several randomized controlled trials show yoga is an effective treatment. However, the comparative effectiveness of yoga and physical therapy, a common mainstream treatment for chronic low back pain, is unknown.
This is a randomized controlled trial for 320 predominantly low-income minority adults with chronic low back pain, comparing yoga, physical therapy, and education. Inclusion criteria are adults 18-64 years old with non-specific low back pain lasting >=12 weeks and a self-reported average pain intensity of >=4 on a 0-10 scale. Recruitment takes place at Boston Medical Center, an urban academic safety-net hospital and seven federally qualified community health centers located in diverse neighborhoods. The 52-week study has an initial 12-week Treatment Phase where participants are randomized in a 2:2:1 ratio into i) a standardized weekly hatha yoga class supplemented by home practice; ii) a standardized evidence-based exercise therapy protocol adapted from the Treatment Based Classification method, individually delivered by a physical therapist and supplemented by home practice; and iii) education delivered through a self-care book. Co-primary outcome measures are 12-week pain intensity measured on an 11-point numerical rating scale and back-specific function measured using the modified Roland Morris Disability Questionnaire. In the subsequent 40-week Maintenance Phase, yoga participants are re-randomized in a 1:1 ratio to either structured maintenance yoga classes or home practice only. Physical therapy participants are similarly re-randomized to either five booster sessions or home practice only. Education participants continue to follow recommendations of educational materials. We will also assess cost effectiveness from the perspectives of the individual, insurers, and society using claims databases, electronic medical records, self-report cost data, and study records. Qualitative data from interviews will add subjective detail to complement quantitative data.Trial registration: This trial is registered in ClinicalTrials.gov, with the ID number: NCT01343927.

- "Yoga, a form of physical activity consisting of various postures (asanas), breathing and meditation techniques (pranayama) has been shown to be very effective in managing hypertension and diabetes. Yoga is also effective in reducing stress and body weight. Greene's climacteric scale (GCS) measures menopausal symptoms and consists of 21 items listed under three main independent domains, psychological, somatic and vasomotor, fourth being sexual dysfunction.

ABSTRACT: Many women report an increased level of anxiety, irritability and mood swings during their perimenopausal state. Studies show that physically active people can reduce their anxiety and depression by practicing yoga. Serum minerals such as calcium, copper and magnesium and the ferro-oxidase, ceruloplasmin play an important role in the body during the perimenopausal period.
The objective of this study is to assess the serum mineral status, anthropometric parameters and climacteric symptoms in perimenopausal women before and after yoga intervention.
A total of 30 subjects with perimenopausal symptoms, aged between 40 and 60 years (49.43 ± 6.15) were included in the study. Yoga intervention was given on a daily basis (45 min duration) for 12 weeks. The climacteric symptoms were assessed by Greene's climacteric scale and biochemical parameters were analyzed spectrophotometrically.
A significant decrease in the waist hip ratio (P < 0.036) and body mass index (P < 0.036) was observed after yoga intervention. Systolic (P < 0.064) and diastolic (P < 0.082) blood pressure (BP) showed marginal decrease after yoga therapy. Climacteric symptoms improved significantly (P < 0.001) after yoga intervention. A significant increase (P < 0.001) in serum calcium and copper and a marked decrease in serum magnesium (P < 0.05) and ceruloplasmin (P < 0.028) levels was observed, post yoga therapy. Serum magnesium negatively correlated (r = -0.467, P < 0.035) with systolic BP after yoga intervention.
The overall changes observed in the mineral status and climacteric symptoms suggest that yoga therapy protocol can be effectively used to improve the quality of life in perimenopausal women.
