There is evidence that insufficient sleep and more stressors are individually associated with poor metabolic health outcomes. Examining sleep and stressors jointly may account for greater variability in health outcomes; however, we know little about the combined effect of both insufficient sleep and more stressors on metabolic health. This study examined whether experiencing more stressors in response to insufficient sleep ("stressor reactivity to insufficient sleep") was associated with body mass index in middle-aged workers. One-hundred and twenty-seven participants [M(age) = 45.24 +/- 6.22 years] reported nightly sleep characteristics and daily stressors on 8 consecutive days. We collected height and weight measurements to calculate body mass index [kg m(-2)]. On average, workers reported more stressors following nights with shorter-than-usual sleep duration or poorer-than-usual sleep quality (negative slope means higher stressor reactivity to insufficient sleep). When examining stressor reactivity to insufficient sleep with insufficient sleep represented by shorter-than-usual sleep duration, compared with those with average stressor reactivity to insufficient sleep (within +/- 1/2 SD; reference), workers with high stressor reactivity to insufficient sleep (≤ -1/2 SD) had higher body mass index (B = 3.24, p < .05). The body mass index of these workers fell in the obese range. There was no difference in body mass index between workers with low stressor reactivity to insufficient sleep (>/= -1/2 SD) and the reference group. When examining stressor reactivity to insufficient sleep with insufficient sleep represented by poorer-than-usual sleep quality, stressor reactivity to insufficient sleep was not significantly associated with body mass index. Results suggest that middle-aged workers with higher stressor reactivity to insufficient sleep duration may be at greater risk for obesity. Results may inform future studies on interventions for improving sleep and reducing stress in middle-aged workers.
