158 males employees in the metal industry, aged 35-44 years, were examined to determine the prevalence of tenderness and pain in the neck and shoulders. Type A behaviour was assessed by a series of 16 questions. One or more tender sites were found in 30% and more than three in 7% of the examined employees. Tenderness was twice as common among those with interview-based pain in the past 12 months (40%) as among those without pain (23%). Those with tenderness on palpation more often had a type A behaviour than those without tenderness (p = 0.010). The association was modified by pain but not by occupation. One explanation for the association between tenderness and behaviour might be that type A personality is associated with increased muscle activity in the neck and shoulders leading to muscular fatigue and tenderness.
对158名年龄在35至44岁之间的金属行业男性员工进行了检查，以确定颈部和肩部压痛及疼痛的患病率。通过一系列16个问题评估A型行为。在30%的受检员工中发现了一个或多个压痛部位，7%的员工有三个以上的压痛部位。在过去12个月中有基于访谈的疼痛的员工中，压痛的发生率（40%）是无疼痛员工（23%）的两倍。触诊时有压痛的员工比无压痛的员工更常表现出A型行为（p = 0.010）。这种关联受疼痛影响，但不受职业影响。压痛与行为之间关联的一种解释可能是，A型人格与颈部和肩部肌肉活动增加有关，导致肌肉疲劳和压痛。
