Shift workers may be at risk of different diseases. In order to assess cardiometabolic risk in shift workers, a cross-sectional study was performed among active workers.
A total of 481 workers (121 men, 360 women) were investigated; most of them were employees in light industry (58.2%) or in public services (23.9%). Past medical history was recorded and physical examination was performed. Questionnaires were used to characterize daily activity. Fasting venous blood sample was collected for measuring laboratory parameters. Data from shift workers (n = 234, age: 43.9 ± 8.1 years) were compared to those of daytime workers (n = 247, age: 42.8 ± 8.5 years), men and women were analyzed separately.
In men, systolic blood pressure was higher in shift workers compared to daytime workers (133 ± 8 vs 126 ± 17 mmHg; p < 0.05). In women, weight (73.6 ± 15.5 vs 67.7 ± 13.2 kg; p < 0.001), body mass index (27.5 ± 5.7 vs 25.0 ± 4.3 kg/m2; p<0.001) and the prevalence rate of hypertension in the past medical history (24.4 vs 13.4%; p < 0.01) were higher in shift workers compared to daytime workers. In addition, the proportion of current smokers was higher (37.7 vs 21.7%; p < 0.001) and HDL-cholesterol level was lower (1.56 ± 0.32 vs 1.68 ± 0.36 mmol/l; p < 0.01) in female shift workers than in female daytime workers. Both in men and in women, rotating shift workers spent less time sleeping both on working days and on non-working days, spent less time with sport activity, drank more coffee and they spent less time working per day, especially in light physical work, compared to daytime workers. In addition, low and middle educational levels were most frequently found among rotating shift workers as opposed to the daytime workers where high educational level was more common.
Middle-aged active shift workers, especially women, have a less healthy lifestyle and are at higher cardiometabolic risk as compared to daytime workers. Our study highlights the importance of measures for identifying and preventing cardiometabolic risk factors in shift workers.
轮班工人可能面临不同疾病的风险。为了评估轮班工人的心脏代谢风险，对在职工人进行了一项横断面研究。
共调查了 481 名工人（男 121 名，女 360 名）；其中大多数是轻工业（58.2%）或公共服务行业（23.9%）的雇员。记录既往病史并进行体格检查。使用问卷描述日常活动。采集空腹静脉血样检测实验室参数。将轮班工人（n=234，年龄：43.9±8.1 岁）的数据与白班工人（n=247，年龄：42.8±8.5 岁）的数据进行比较，分别对男性和女性进行分析。
在男性中，与白班工人相比，轮班工人的收缩压更高（133±8 比 126±17mmHg；p＜0.05）。在女性中，体重（73.6±15.5 比 67.7±13.2kg；p＜0.001）、体重指数（27.5±5.7 比 25.0±4.3kg/m2；p＜0.001）和既往高血压患病率（24.4 比 13.4%；p＜0.01）在轮班工人中更高。此外，轮班工人中当前吸烟者的比例更高（37.7 比 21.7%；p＜0.001），高密度脂蛋白胆固醇水平更低（1.56±0.32 比 1.68±0.36mmol/l；p＜0.01）。与女性白班工人相比，女性轮班工人工作日和休息日的睡眠时间更短，体育活动时间更少，喝咖啡更多，每天工作时间更短，尤其是从事低体力劳动工作的时间更短。此外，与白班工人相比，轮班工人中低学历和中等学历的比例更高，而高学历的比例则较低。
中年活跃的轮班工人，尤其是女性，生活方式不太健康，心脏代谢风险高于白班工人。我们的研究强调了识别和预防轮班工人心脏代谢危险因素的重要性。
