This study aimed to identify subgroups of active duty U.S. service members (ADSMs) based on physical activity levels and their association with cardiovascular disease (CVD) risk factors. Our secondary aim was to assess how these profiles vary across sociodemographic factors.
A cross-sectional survey of ADSMs, yielding a 9.6% response rate and 17,166 usable surveys, was conducted by the DoD and RAND Corporation in 2018 using stratified random sampling. In this secondary analysis, latent subgroups of ADSMs were determined based on physical activity levels and a weighted multinomial logistic regression was used to examine associations.
Three latent subgroups were identified as "High Activity" (17.1%), "Moderate Activity" (45.3%), and "Low Active" (37.6%). Older age, female, White (as compared to Hispanic), cohabiting, Air Force, Navy, and Coast Guard were associated with increased odds of "Low Active" membership. Compared to the "Low Active" class, the "High Active" class showed lower odds of hyperlipidemia (aOR = 0.62, 95% CI: 0.38, 0.99), hypertension (aOR = 0.69, 95% CI: 0.48, 0.98), and multimorbidity (aOR = 0.55, 95% CI: 0.38, 0.80). Compared to the "Low Active" class, the "Moderate Active" class showed lower odds of hyperlipidemia (aOR = 0.62, 95% CI: 0.47, 0.81) and multimorbidity (aOR = 0.66, 95% CI: 0.53, 0.83). Similar patterns of associations were seen in ADSMs who met the objectives for Healthy People 2030 (HP2030) standards.
The study emphasizes the importance of combining physical activity and strength training to reduce CVD risk factors, supporting the implementation of tailored physical activity programs within the military to align fitness standards.
本研究旨在根据身体活动水平确定美国现役军人（ADSMs）的亚组及其与心血管疾病（CVD）风险因素的关联。我们的次要目标是评估这些特征在社会人口统计学因素方面的差异。
2018年，美国国防部和兰德公司采用分层随机抽样对ADSMs进行了横断面调查，回复率为9.6%，获得了17166份可用调查问卷。在这项二次分析中，根据身体活动水平确定了ADSMs的潜在亚组，并使用加权多项逻辑回归来检验关联。
确定了三个潜在亚组，分别为“高活动水平”（17.1%）、“中等活动水平”（45.3%）和“低活动水平”（37.6%）。年龄较大、女性、白人（与西班牙裔相比）、同居、空军、海军和海岸警卫队与“低活动水平”成员的几率增加有关。与“低活动水平”组相比，“高活动水平”组出现高脂血症（调整后比值比[aOR]=0.62，95%置信区间[CI]：0.38，0.99）、高血压（aOR=0.69，95%CI：0.48，0.98）和多种疾病并存（aOR=0.55，95%CI：0.38，0.80）的几率较低。与“低活动水平”组相比，“中等活动水平”组出现高脂血症（aOR=0.62，95%CI：0.47，0.81）和多种疾病并存（aOR=0.66，95%CI：0.53，0.83）的几率较低。在符合《2030年健康人》（HP2030）标准目标的ADSMs中也观察到了类似的关联模式。
该研究强调了将体育活动和力量训练相结合以降低心血管疾病风险因素的重要性，支持在军队中实施量身定制的体育活动计划以符合健康标准。
