Cardiovascular disease (CVD) is documented as the leading cause of mortality in on-duty firefighters.
To examine the prevalence of metabolic syndrome (MetS) components, cardiorespiratory fitness levels and the association between them in firefighters in Colorado, USA.
This study included male and female Colorado firefighters. MetS was identified where three or more metabolic abnormalities were present, using Cholesterol Education Program/Adult Treatment Panel III guidelines. Cardiorespiratory fitness (indicated by VO2 max) was evaluated with the Bruce protocol. Poisson regression was conducted to examine the association between MetS components and VO2 max.
Among the 947 male and 76 female study subjects, MetS was present in 9% of all firefighters, in 5% of females and 10% of males. The mean age was 37 ± 10 years. MetS prevalence increased with age (from 3% at age <30 to 17% at 50 and older, data not shown). In addition, 35% had one and 19% had two abnormal MetS components and 49% of participants did not meet the minimum recommended VO2 max of 42.0 ml/kg/min. VO2 max was negatively associated with abnormal MetS components (incident rate ratios = 0.95, 95% confidence interval 0.94-0.96, P < 0.001).
About one in 10 of these Colorado firefighters had MetS and nearly half had insufficient cardiorespiratory fitness. Comprehensive CVD risk management and cardiorespiratory fitness improvement are essential for firefighter health and safety.
心血管疾病（CVD）是在职消防员死亡的主要原因。
检查美国科罗拉多州消防员代谢综合征（MetS）成分、心肺适能水平及其相关性。
本研究纳入了科罗拉多州的男性和女性消防员。采用胆固醇教育计划/成人治疗小组 III 指南，若存在三种或更多代谢异常，则确定为 MetS。心肺适能（以 VO2 max 表示）采用布鲁斯方案进行评估。采用泊松回归检验 MetS 成分与 VO2 max 之间的关联。
在 947 名男性和 76 名女性研究对象中，所有消防员中有 9%存在 MetS，女性为 5%，男性为 10%。平均年龄为 37 ± 10 岁。MetS 患病率随年龄增加而增加（从<30 岁时的 3%到 50 岁及以上时的 17%，数据未显示）。此外，35%的人有一个异常的 MetS 成分，19%的人有两个异常的 MetS 成分，49%的参与者没有达到 42.0ml/kg/min 的最低推荐 VO2 max。VO2 max 与异常 MetS 成分呈负相关（发生率比=0.95，95%置信区间 0.94-0.96，P<0.001）。
这些科罗拉多州消防员中约有十分之一患有 MetS，近一半人的心肺适能不足。综合 CVD 风险管理和心肺适能改善对于消防员的健康和安全至关重要。
