Abstract
Purpose: This study explored the relationship between migrant farmworker (MFW) stress and salivary cortisol (sC) in a sample of MFWs prior to migration. Sample: The sample, 40 ( N = 14 male, 26 female) adult MFWs residing in the lower Rio Grande Valley of Texas, primarily comprised middle-aged immigrants with a middle-school education. Design: This pilot feasibility study included a self-report farmworker stress inventory and five serial sC specimens in 24 hr. Results: The sC measures reflected an expected diurnal pattern. Lower total cortisol (area under the curve with respect to ground) was significantly associated with greater waist circumference ( r = –.63, p ≤ .01). Repeated measures analysis of variance (ANOVA) indicated that participants who perceived high levels of farmworker stress exhibited a significant change in sC over time; F(2.14, 72.65) = 43.90, p < .001. High- and low-perceived-stress groups differed significantly in the trajectory of changes in sC over the five time points. Conclusion: MFWs experienced significant levels of stress during premigration. Their sC responses varied significantly by level of perceived farmworker stress. Lower perceived stress may reflect blunting of the sC response pattern.
