Abstract Background Despite established links between reduced nocturnal blood pressure (BP) dipping and cardiovascular disease, BP dipping research in Hispanics is limited. Purpose This study investigated socioeconomic status (SES) as a predictor of BP dipping and the contributions of psychosocial factors to this relationship. Analyses were A. L.

conducted for the overall sample and separately for higher and lower acculturated women. Methods Mexican-American women (N0291; 40–65 years) reported demographics and completed psychosocial assessments and 36-h ambulatory BP monitoring. Results Lower SES related to reduced BP dipping in the overall sample and in more US-acculturated women (r’s0.17–.30, p’s.10). An indirect effect model from SES to BP dipping via psychosocial resources/risk fits well across samples. Conclusions In Mexican-American women, the nature of SES gradients in BP dipping and the roles of psychosocial resources/risk differ by acculturation level. Keywords Ambulatory blood pressure . Nocturnal blood pressure dipping . Hispanic . Psychosocial . Socioeconomic status A substantial body of evidence suggests that ambulatory blood pressure (BP) measures are more predictive of cardiovascular disease outcomes than clinic or resting assessments [1–4]. In addition to elevations in average BP levels during ambulatory monitoring, the circadian variability of BP may provide important information about cardiovascular disease risk. Specifically, during 24-h ambulatory monitoring, intraindividual variations in BP typically follow a rhythm in which BP falls to its lowest levels in the hours following sleep onset and then demonstrates a marked surge during the transition from sleep to wakefulness. The average 10–20 % decline in BP levels during sleep relative to waking is known as noctur
