BACKGROUND Health trends, which promote performance enhancement and maintaining or increasing muscle strength, may appeal to soldiers looking to maintain health standards set by the US Army, but often these trends require further investigation to assess safety and efficacy. High-intensity interval training (HIIT) and use of weight loss and/or performance-enhancing/body-building dietary supplements (WL/PES DS) are two such trends that, if implemented inappropriately, can negatively impact soldier health and readiness. OBJECTIVE Our aim was to establish health/psychosocial profiles of US Army soldiers who participate in HIIT and/or use WL/PES DS. DESIGN This cross-sectional observational study used data from the 2016 US Army Global Assessment Tool. PARTICIPANTS Data were analyzed from respondents to the 2016 US Army Global Assessment Tool (n=299,996) who consented to have their data used for research purposes. RESULTS Soldiers were classified into four groups based on HIIT and/or WL/PES DS use. Thirty-five percent of soldiers participated in HIIT and 10% took WL/PES DS at least once per month in the last year. HIIT participation was associated with higher reported odds of healthy behaviors and higher emotional and social fitness. In contrast to HIIT, WL/PES DS use was associated with higher reported odds of risky behaviors (hazardous drinking and tobacco use) and lower psychosocial fitness. The group participating in HIIT but not using WL/PES DS reported fewer unhealthy behaviors compared to the HIIT+WL/PES DS and WL/PES DS-only groups. CONCLUSIONS Engaging in HIIT is associated with higher reported odds of healthy behaviors and increased psychosocial fitness. However, soldiers who engaged in HIIT also have increased odds of WL/PES DS use, which is associated with greater reported risky behaviors and reduced fitness. Although HIIT and WL/PES DS use are related, they are associated with different reported health/risky behaviors and different psychosocial attributes.

美国士兵的健康行为和社会心理特征

背景技术促进性能增强和维持或增加肌肉力量的健康趋势可能会吸引希望维持美国陆军设定的健康标准的士兵，但通常这些趋势需要进一步调查以评估安全性和有效性。高强度间歇训练 (HIIT) 和使用减肥和/或增强性能/健美的膳食补充剂 (WL/PES DS) 是两个这样的趋势，如果实施不当，会对士兵的健康和战备状态产生负面影响。目标 我们的目标是建立参与 HIIT 和/或使用 WL/PES DS 的美国陆军士兵的健康/心理社会档案。设计这项横断面观察性研究使用了 2016 年美国陆军全球评估工具的数据。参与者 对 2016 年美国陆军全球评估工具（n=299，996）谁同意将他们的数据用于研究目的。结果 根据 HIIT 和/或 WL/PES DS 的使用情况，士兵被分为四组。去年，35% 的士兵参加了 HIIT，10% 的士兵每月至少参加一次 WL/PES DS。HIIT 参与与更高的健康行为几率以及更高的情绪和社交健康相关。与 HIIT 相比，WL/PES DS 的使用与更高的风险行为（危险饮酒和吸烟）和较低的社会心理适应度相关。与 HIIT+WL/PES DS 和仅 WL/PES DS 组相比，参与 HIIT 但不使用 WL/PES DS 的组报告的不健康行为更少。结论 参与 HIIT 与更高的健康行为几率和增加的社会心理健康相关。然而，参与 HIIT 的士兵也增加了使用 WL/PES DS 的几率，这与报告的风险行为和健康下降有关。尽管 HIIT 和 WL/PES DS 的使用是相关的，但它们与报告的不同健康/危险行为和不同的社会心理属性有关。
