To examine the independent and joint effects of psychosocial chronic and acute stressors with weight status and to report the intraclass correlation coefficient for body mass index (BMI).
Baseline data on 2782 employees from a group-randomized weight gain prevention intervention were examined to investigate the effect of high job strain and job insecurity on BMI and on the odds of overweight/obesity including potential confounders and mediating variables. Data were analyzed using mixed models.
The mediating variables removed the effect of high job strain on weight (beta = 0.68, P = 0.07; odds ratios = 1.34, confidence interval = 1.00 to 1.80) whereas job insecurity was never significant. Intraclass correlation coefficient for BMI is 0.0195, 0.0193, and 0.0346 overall, for men and women, respectively.
Worksite wellness should target health enhancing behaviors to minimize the health effects of psychosocial work conditions.
研究心理社会慢性和急性应激源与体重状况的独立和联合作用,并报告体重指数(BMI)的组内相关系数。
对一项群组随机体重增加预防干预的 2782 名员工的基线数据进行了检查,以调查高工作压力和工作不安全感对 BMI 以及超重/肥胖的几率的影响,包括潜在的混杂变量和中介变量。使用混合模型进行数据分析。
中介变量消除了高工作压力对体重的影响(β=0.68,P=0.07;比值比=1.34,置信区间=1.00 至 1.80),而工作不安全感从未具有统计学意义。BMI 的组内相关系数分别为 0.0195、0.0193 和 0.0346,总体而言,男性和女性分别为 0.0195、0.0193 和 0.0346。
