Attachment Orientations, Respiratory Sinus Arrhythmia, and Stress Are Important for Understanding the Link Between Childhood Socioeconomic Status and Adult Self-Reported Health.
BACKGROUND
Low childhood socioeconomic status (SES) is reliably associated with poor adult health. Social environments early in life and physiological stress responses are theorized to underlie this link; however, the role of attachment orientations is relatively unknown.


OBJECTIVE
In this study, we examined whether attachment orientations (i.e., attachment anxiety and attachment avoidance) and self-reported stress were mediators of the association between childhood SES and self-reported health in adulthood. Furthermore, we examined whether parasympathetic nervous system functioning was a moderator of associations between attachment orientations and self-reported stress.


METHODS
Participants (N = 213) provided self-reports of childhood SES, attachment orientations, general stress, and self-rated health. Respiratory sinus arrhythmia (RSA) was measured at rest, as well as during an acute social stressor.


RESULTS
Low childhood SES was associated with poor self-reported health via the serial pathway from attachment anxiety to general stress. Moreover, attachment avoidance was associated with self-reported health via general stress, but only among those with high stress-induced RSA. Findings were independent of participant age, sex, race, body mass index, baseline RSA, and adult SES.


CONCLUSIONS
Attachment theory is useful for understanding why those from low SES backgrounds are at greater risk of negative health outcomes in adulthood. Findings extend our knowledge of how interpersonal relationships in childhood can shape emotional and physical health outcomes in adulthood.
