Stress contributes to dietary patterns that impede health. Yoga is an integrative stress management approach associated with improved dietary patterns in burgeoning research. Yet, no research has examined change in dietary patterns, body mass index (BMI), and stress during a yoga intervention among stressed adults with poor diet.
Objectively-measured BMI and a battery of self-report questionnaires were collected at four time points during and following a 12-week yoga intervention (N = 78, 71% women, mean BMI = 25.69 kg/m±4.59) - pre-treatment (T1), mid-treatment (6 weeks; T2), post-treatment (12 weeks; T3), and at 3-month follow-up (24 weeks; T4).
T1 to T3 fruit and vegetable intake, BMI, and stress significantly declined in the overall sample. Reduction in vegetable intake was no longer significant after accounting for reductions in caloric intake, and reduction in caloric intake remained significant after accounting for reductions in stress.
Findings may be interpreted as yoga either encouraging or adversely impacting healthy dietary patterns (i.e., minimizing likelihood of future weight gain vs. decreasing vegetable intake and overall caloric intake among individuals who may not need to lose weight, respectively). Continued research is warranted, utilizing causal designs.
压力会导致妨碍健康的饮食模式。瑜伽是一种综合的压力管理方法，与新兴研究中改善饮食模式有关。然而，在饮食不良的压力大的成年人中，还没有研究在瑜伽干预期间和之后检查饮食模式、体重指数（BMI）和压力的变化。
在 12 周的瑜伽干预期间和之后的四个时间点（N=78，71%为女性，平均 BMI=25.69kg/m±4.59）-治疗前（T1）、治疗中期（6 周；T2）、治疗后（12 周；T3）和 3 个月随访（24 周；T4），收集了客观测量的 BMI 和一系列自我报告问卷。
总体样本中，T1 至 T3 的水果和蔬菜摄入量、BMI 和压力均显著下降。在考虑到热量摄入减少后，蔬菜摄入量的减少不再显著，而在考虑到压力减少后，热量摄入的减少仍然显著。
研究结果可以解释为瑜伽可能会鼓励或对健康的饮食模式产生不利影响（即，减少未来体重增加的可能性，与那些可能不需要减肥的人减少蔬菜摄入量和总热量摄入相对比）。需要进行进一步的研究，采用因果设计。
