Wives' and husbands' cortisol reactivity to proximal and distal dimensions of couple conflict.

ABSTRACT: Poor marital quality has been linked repeatedly to spouses' health problems, with alterations to physiological stress response systems, such as the hypothalamic-pituitary-adrenocortical (HPA) axis, as one putative mechanism. This study assessed wives' and husbands' HPA axis (i.e., cortisol) reactivity to marital criticism during laboratory-based conflict discussions, in the context of marital aggression experienced during the previous year. Ninety-five couples provided one saliva sample prior to-and three samples following-a triadic family conflict discussion involving their teenage child. Marital criticism during the conflict discussion was related to heightened HPA reactivity for husbands only. For wives, an interaction emerged between criticism during the conflict and previous-year marital aggression: only those wives who had experienced high levels of marital aggression demonstrated a positive association between criticism and cortisol output. Husbands thus appeared to be more physiologically reactive to the in-the-moment critical behaviors, whereas wives' responses to proximal conflict were related to previous and perhaps more chronic experiences of marital aggression. These findings shed light on ways in which within-couple processes during family conflicts involving children contribute to individual physiological functioning, enhancing our understanding of the role of family relationships in physical health outcomes.

Project description:Distal hair segments collected at delivery may allow for the assessment of maternal cortisol secretion in early pregnancy, an important time window for fetal development. Therefore, an investigation of the validity of distal hair cortisol concentrations is warranted. We examined the concordance between proximal and distal hair cortisol concentrations (HCC), both representing the first trimester of pregnancy. The study population was comprised of a random sample of 97 women participating in the Pregnancy Outcomes Maternal and Infant Study, a prospective cohort study of pregnant women attending prenatal clinics in Lima, Peru. Each participant provided two hair samples: once at enrollment [mean gestational age (GA) = 13.1 weeks] and again at full-term delivery (mean GA = 39.0 weeks). Hair segments reflecting the first trimester were: 3 cm hair segments closest to the scalp on the first hair sample (proximal) and 6-9 cm from the scalp on the second hair sample (distal). HCC was determined using Luminescence Immunoassay. A subset (N = 28) had both hair segments additionally analyzed using liquid chromatography tandem mass spectrometry (LC-MS/MS). HCC values were log-transformed (logHCC), and proximal-distal differences tested using paired sample t-tests. Concordance was evaluated within and across assay types. LogHCC, measured using immunoassay, in distal hair segments was lower compared to proximal hair segments (1.35 versus 1.64 respectively; p = .02). No difference was observed using LC-MS/MS (1.99 versus 1.83, respectively; p=.33). Proximal-distal concordance was low within assay (immunoassay: Pearson = 0.27 and κ = 0.10; LC-MS/MS: Pearson = 0.37 and κ = 0.07). High correlation was observed across assays for both distal (Pearson = 0.78, p < .001; κ = 0.64) and proximal segments (Pearson = 0.96, p < .001; κ = 0.75). In conclusion, distal first-trimester hair segments collected at delivery have lower absolute HCC compared to HCC in proximal first trimester hair segments collected in early pregnancy, and are poorly concordant with HCC in proximal segments. Findings may inform the design of future studies.
