Job stress, social support and health amongst shrimp fishermen

Samples of shrimp fishermen (n = 211) and land-based workers (n = 99) drawn from a US Gulf Coast community are compared with regard to their degree of exposure to occupational stressors, level of social support, and extent of non-clinical depression and somatization. As hypothesized, shrimp fishermen report significantly greater levels of stressor exposure, support, depression and somatization at the zero-order level. At the multivariate level, with several covariates controlled, shrimpers report greater levels of stressor exposure, support and somatization. A model of the stress process which hypothesizes positive effects of stressors, and direct and indirect negative effects of social support on distress, is evaluated for each group. Occupational stressors predict as hypothesized, but social support does not. An explanation is offered which emphasizes the migratory character of shrimping as an occupation.     

Job relocation: Stress and the role of the family

Job relocation is an accepted feature of the career structure for an ever increasing number of employees. Moving from one work environment to another, coupled with relocating the family, can induce stress and so influence performance at work. This paper reviews the available evidence concerning possible roles the family may play in the relocation process. It is argued that a systemic approach is ideally suited to unravelling the complex relationship between work and home environments that underlies the process of individual and family adaptation to relocation. This relationship must be understood in order to provide constructive advice to employers concerning effective relocation policies.     

Providing maternity care for disadvantaged women in Aotearoa New Zealand: The impact on midwives

BackgroundHealth inequities and socio-economic disadvantage are causes for concern in Aotearoa New Zealand. Becoming pregnant can increase a woman’s vulnerability to poverty, with the potential for an increase in multiple stressful life events. Providing midwifery care to women living in socio-economic deprivation has been found to add additional strains for midwives. Exploring the perspectives of the midwives providing care to women living with socio-economic deprivation can illuminate the complexities of maternity care.AimTo explore the impact on midwives when providing care for socio-economically disadvantaged women in Aotearoa New Zealand.MethodInductive thematic analysis was used to analyse an open-ended question from a survey that asked midwives to share a story around maternal disadvantage and midwifery care.FindingsA total of 214 stories were received from midwives who responded to the survey. Providing care to disadvantaged women had an impact on midwives by incurring increased personal costs (time, financial and emotional), requiring them to navigate threats and uncertainty and to feel the need to remedy structural inequities for women and their wider families. These three themes were moderated by the relationships midwives held with women and affected the way midwives worked across the different maternity settings.ConclusionMidwives carry a greater load when providing care to socio-economically deprived women. Enabling midwives to continue to provide the necessary support for women living in socio-economic deprivation is imperative and requires additional resources and funding.

Prenatal stress,health, and health behaviours during the COVID-19 pandemic: An international survey

BackgroundPregnant women’s stress, mental and physical health, and health behaviours can have important implications for maternal and child health outcomes.AimTo examine pregnant women’s levels of stress, mental and physical health, and health behaviours during the COVID-19 pandemic.MethodsA cross-sectional survey was conducted online, with recruitment and data collection occurring between 16/6/20 and 17/7/20. Participants were pregnant women recruited via online pregnancy/parenting communities. Participants self-reported their levels of general stress, pregnancy-specific stress and COVID-19 related stress, mental and physical health, general health behaviours, and COVID-19 related health behaviours.Findings573 pregnant women participated in the survey. Participants were most commonly resident in the United States (42.6%, n = 243), Ireland (41.2%, n = 235) or the United Kingdom (10%, n = 57). The majority (80.0%, n = 457) were married and educated to degree level or above (79.3, n = 453). Pregnant women reported high levels of pregnancy-specific and COVID-19-related stress, and low levels of mental and physical health, during the pandemic. Encouragingly, pregnant women in this study generally reported high levels of adherence to public health advice and pregnancy health behaviours. Stress and general mental health outcomes were best predicted by well-being factors (including stress and social support). Health impairing behaviours (e.g. poor diet) were predicted by both well-being and demographic factors.DiscussionInterventions targeting pregnancy- and pandemic-specific stress at the population level will be essential to support mental health and minimise adverse outcomes for women and children during the pandemic.     

The impacts of the COVID-19 pandemic on birth satisfaction in a prospective cohort of 2,341 U.S. women

ProblemBirth satisfaction is an important health outcome that is related to postpartum mood, infant caretaking, and future pregnancy intention.BackgroundThe COVID-19 pandemic profoundly affected antenatal care and intrapartum practices that may reduce birth satisfaction.AimTo investigate the extent to which pandemic-related factors predicted lower birth satisfaction.Methods2341 women who were recruited prenatally in April–May 2020 and reported a live birth between April–October 2020 were included in the current analysis. Hierarchical linear regression to predict birth satisfaction from well-established predictors of birth satisfaction (step 1) and from pandemic-related factors (step 2) was conducted. Additionally, the indirect associations of pandemic-related stress with birth satisfaction were investigated.FindingsThe first step of the regression explained 35% of variance in birth satisfaction. In the second step, pandemic-related factors explained an additional 3% of variance in birth satisfaction. Maternal stress about feeling unprepared for birth due to the pandemic and restrictions on companions during birth independently predicted lower birth satisfaction beyond the non-pandemic variables. Pandemic-related unpreparedness stress was associated with more medicalized birth and greater incongruence with birth preference, thus also indirectly influencing birth satisfaction through a mediation process.DiscussionWell-established contributors to birth satisfaction remained potent during the pandemic. In addition, maternal stress and restriction on accompaniment to birth were associated with a small but significant reduction in birth satisfaction.ConclusionStudy findings suggest that helping women set flexible and reasonable expectations for birth and allowing at least one intrapartum support person can improve birth satisfaction.
