先前的研究支持生活在马萨诸塞州波士顿地区的波多黎各成年人的心理压力和慢性疾病之间的关系。压力可能通过影响饮食和身体活动模式来影响健康。因此，在生活在马萨诸塞州波士顿地区的>1300名波多黎各人（年龄45-75岁; 70%为女性）中，研究了感知压力和两种假设的压力相关食物摄入介质胰岛素和皮质醇与饮食和活动模式的可能关联。使用多元线性回归和ANCOVA分析数据。更大的感知压力与更低的水果，蔬菜和蛋白质摄入量，更多的咸味零食消费和更少的体育活动参与有关。压力与甜食摄入量增加有关，特别是在2型糖尿病患者中。在没有糖尿病的人中，皮质醇和压力呈正相关。皮质醇与高饱和脂肪摄入有关，糖尿病患者则与甜食有关。独立于糖尿病，感知压力与较高的循环胰岛素和BMI相关。我们的研究结果支持了这一人群中压力、皮质醇、饮食和活动模式之间的联系。对于高糖食物，这种关系在2型糖尿病患者中可能特别重要。有必要进行纵向研究来确定这些已确定关联的因果途径。由爱思唯尔有限公司发布
Previous research supports a relationship between psychological stress and chronic disease in Puerto Rican adults living in the Boston, Massachusetts area. Stress may affect health by influencing dietary and physical activity patterns. Therefore, perceived stress and two hypothesized mediators of stress-related food intake, insulin and cortisol, were examined for possible associations with dietary and activity patterns in >1300 Puerto Ricans (aged 45-75 years; 70% women) living in the Boston, Massachusetts area. Data were analyzed using multiple linear regression and ANCOVA. Greater perceived stress was associated with lower fruit, vegetable, and protein intake, greater consumption of salty snacks, and lower participation in physical activity. Stress was associated with higher intake of sweets, particularly in those with type 2 diabetes. Cortisol and stress were positively associated in those without diabetes. Cortisol was associated with higher intake of saturated fat and, in those with diabetes, sweet foods. Independent of diabetes, perceived stress was associated with higher circulating insulin and BMI. Our findings support a link between stress, cortisol, and dietary and activity patterns in this population. For high-sugar foods, this relationship may be particularly important in those with type 2 diabetes. Longitudinal research to determine causal pathways for these identified associations is warranted.
