Hispanic college students face high stress, which may increase their risk for chronic stress-related health issues. Effective and accessible stress management strategies for this population remain limited.
This pilot study filled a gap by studying the effects of psychological stress on diet and physical activity habits and evaluating the impact of moderate-intensity physical exercise (MIPE) and yoga interventions on chronic psychological stress and acute stress responses among Hispanic college students.
A total of 18 Hispanic college students participated in a 6-week intervention consisting of either MIPE or yoga, conducted twice weekly. Anthropometric measurements and lifestyle data were collected at both pre- and post-intervention timepoints. Psychological stress was evaluated using the Perceived Stress Scale-10 (PSS-10), morning salivary cortisol concentrations, and the Trier Social Stress Test (TSST).
Before the intervention, both perceived stress scores and morning salivary cortisol concentrations were positively correlated with the frequency of sweetened beverage intake and negatively correlated with attitudes toward exercise. Psychological stress was not significantly reduced after MIPE or yoga interventions. The salivary cortisol response to TSST was significantly improved after the yoga intervention.
Although this pilot exploratory study suggests that short-term yoga may have beneficial effects in managing acute stress response in Hispanic college students, the efficacy of the interventions needs to be tested and replicated in a fully powered trial.
西班牙裔大学生面临着高压力，这可能会增加他们患与慢性压力相关健康问题的风险。针对这一人群的有效且可及的压力管理策略仍然有限。
这项试点研究通过研究心理压力对饮食和身体活动习惯的影响，并评估中等强度体育锻炼（MIPE）和瑜伽干预对西班牙裔大学生慢性心理压力和急性应激反应的影响，填补了一项空白。
共有18名西班牙裔大学生参加了一项为期6周的干预，干预内容为每周两次的MIPE或瑜伽。在干预前和干预后的时间点收集人体测量数据和生活方式数据。使用感知压力量表-10（PSS-10）、早晨唾液皮质醇浓度和特里尔社会应激测试（TSST）评估心理压力。
在干预前，感知压力得分和早晨唾液皮质醇浓度均与含糖饮料摄入频率呈正相关，与对运动的态度呈负相关。MIPE或瑜伽干预后，心理压力没有显著降低。瑜伽干预后，唾液皮质醇对TSST的反应显著改善。
尽管这项试点探索性研究表明，短期瑜伽可能对管理西班牙裔大学生的急性应激反应有有益影响，但干预的效果需要在一项充分有力的试验中进行测试和重复验证。
