Relationships among psychosocial factors, biomarkers, preeclampsia, and preterm birth in African American women: a pilot.

AIM: To explore the relationships among psychosocial factors (optimism, uncertainty, social support, coping, psychological distress), biomarkers (cortisol, cytokines), preeclampsia, and preterm birth in African American women. METHODS: Forty-nine pregnant African American women completed psychosocial questionnaires and had blood collected for biomarkers between 26 and 36 weeks of gestation. Birth outcomes were obtained from birth records. RESULTS: Women reporting higher levels of social support had lower levels of pro-inflammatory cytokines (IL-2, IL-5, and IL-6). Surprisingly, compared with low-risk pregnant women, women diagnosed with preeclampsia reported more optimism and less avoidance, and had lower levels of cortisol and IFN-γ. Similarly, compared to women with full-term birth, women with preterm birth reported higher levels of optimism and lower levels of avoidance, and had lower levels of IL-10. CONCLUSION: Psychosocial factors influence inflammation and pregnancy outcomes. Close assessment and monitoring of psychosocial factors may contribute to improved pregnancy outcomes.

Job strain and psychological distress among employed pregnant Thai women: role of social support and coping strategies.

Most Thai women continue to work throughout their pregnancy; however, little is known about job strain and its relation to psychological distress. This study aimed to examine: (1) the direct effects of job strain, perceived workplace support, perceived family support, and coping strategies on psychological distress and (2) the moderating effect of perceived workplace support, perceived family support, and coping strategies on the relationship between job strain and psychological distress. Lazarus and Folkman's transactional model of stress and coping guided this cross-sectional study. Full-time employed pregnant women (N = 300) were recruited from three antenatal clinics in Thailand. Thai versions of the following instruments were used: the State-Anxiety Inventory and Center for Epidemiological Studies-Depression Scale (psychological distress), the Job Content Questionnaire (job strain and perceived workplace support), the Medical Outcome Study Social Support Survey (perceived family support), and the Ways of Coping Checklist-Revised (coping strategies). Job strain with other predictors explained 54% of the variance in psychological distress. In the separate hierarchical multiple linear regression models, two types of coping strategies, seeking social support and wishful thinking, moderated the effects of job strain on psychological distress. Perceived family support had a direct effect in reducing psychological distress. Job strain is a significant contributor to psychological distress. The average levels of seeking social support and wishful thinking were most beneficial in moderating the negative impact of job strain on psychological distress. Since perceived workplace and family support did not have moderating effects, stress management programs for decreasing the levels of job strain should be developed.

Effects of the 2011 flood in Thailand on birth outcomes and perceived social support.

OBJECTIVE: To determine the effects of displacement due to flooding during pregnancy on birth outcomes (infant birth weight and gestational age) and the moderating effect of perceived social support on the relationship between displacement and birth outcomes. DESIGN: A descriptive, longitudinal study. SETTING: A university-affiliated hospital in Pathum Thani, Thailand. PARTICIPANTS: Pregnant women (N = 175) in the third trimester that had uncomplicated pregnancies and no history of mental illness. METHODS: During pregnancy, the participants completed standardized measurements of depression symptoms, perceived social support, and questionnaires concerning the effect of the flood. After giving birth, infant birth weight and gestational age at birth were retrieved from delivery records. RESULTS: Seventy percent (n = 123) of the participants experienced displacement during the flood. The displaced women had a mean infant birth weight of 175 grams less than that of the nondisplaced women, t(173) = -2.38, p = .02, whereas infant gestational age was not different. Displacement and other variables explained approximately 8% of the variance in infant birth weight. The interaction term between displacement and perceived social support was statistically significant and additionally explained the variance in infant birth weight, F(6, 168) = 3.24, p = .005. CONCLUSION: Being displaced during pregnancy due to a natural disaster affected fetal growth rather than length of gestation. Health care providers should closely monitor maternal weight gain and fetal growth of pregnant women who experience displacement. Among the displaced women, social support was associated with higher infant birth weight; therefore, high levels of perceived social support may be protective for pregnant women who experience stressful events such as displacement from flooding.
