Is being childless detrimental to a woman's health and well-being across her life course?

BACKGROUND: Childlessness is a growing phenomenon. Previous research examining health and well-being differentials between women with and without children has produced conflicting results. Most of this research has been conducted in the United States or parts of Europe. There has been limited research in Australia that has examined the health and well-being of women with and without children across the life course. The aim of the current study was to examine the association between motherhood status and general physical and mental health and well-being over a 10-year time period. METHODS: Using 10 waves of data from the Household, Income and Labour Dynamics in Australia study, longitudinal linear mixed models with time varying variables (both dependent and independent) were constructed to assess the effect of childlessness on health and well-being based on the Short Form-36 Health Survey Version 1 (n=52,381 observations). FINDINGS: Findings suggest that childless women experience poorer physical and mental health and well-being during the peak reproductive years; however, this trend is reversed for women aged 65 years or more. Although never-married, childless women experienced better health and well-being compared with mothers, this was not the case for childless women who were divorced, separated, or widowed or in a relationship. CONCLUSION: The findings support the notion that whether or not a woman has children does have consequences for her health and well-being; however, this differs across the life course.

Assessment and optimization of chemical industrial processes from a life cycle perspective

During the PhD program in chemistry, curriculum in environmental chemistry, at the University of Bologna the sustainability of industry was investigated through the application of the LCA methodology. The efforts were focused on the chemical sector in order to investigate reactions dealing with the Green Chemistry and Green Engineering principles, evaluating their sustainability in comparison with traditional pathways by a life cycle perspective. The environmental benefits associated with a reduction in the synthesis steps and the use of renewable feedstock were assessed through a holistic approach selecting two case studies with high relevance from an industrial point of view: the synthesis of acrylonitrile and the production of acrolein. The current approach wants to represent a standardized application of LCA methodology to the chemical sector, which could be extended to several case studies, and also an improvement of the current databases, since the lack of data to fill the inventories of the chemical productions represent a huge limitation, difficult to overcome and that can affects negatively the results of the studies. Results emerged from the analyses confirms that the sustainability in the chemical sector should be evaluated from a cradle-to-gate approach, considering all the stages and flows involved in each pathways in order to avoid shifting the environmental burdens from a steps to another. Moreover, if possible, LCA should be supported by other tools able to investigate the other two dimensions of sustainability represented by the social and economic issues.

Participation in Further Education over the Life Course: a longitudinal study of three birth cohorts in the Federal Republic of Germany

In this paper we address the issue of who is most likely to participate in further training, for what reasons and at what stage of the life course. Special emphasis is given to the impact of labour-market policies to encourage further education and a person's individual or cohort possibilities to participate in further education. We apply a Cox proportional hazard model to data from the West German Life History Study, separately for women and men, within and outside the firm. Younger cohorts show not only higher proportions of participation in further education and training at early stages of the life course, they also continue to participate in higher numbers during later stages of the life course. General labour-force participation reduces and tenure with the same firm increases the propensity to participate in further education and training. Contrary to expectations, in Germany labour-market segmentation has been enhanced rather than reduced by further education and training policies, since in the firm-specific labour-market segment, i.e. skilled jobs in large firms, and in the public sector both women and men had a higher probability of participation. Particularly favourable conditions for participation in further education outside the firm prevailed during the first years of the labour promotion act (Arbeitsförderungsgesetz) between 1969 and 1974, but women did not benefit to the same extent as men. Training policies are, therefore, in need of continuous assessment based on a goal-achievement evaluation to avoid any unintended effects of such policies.

Toxic Stress and Child Hunger Over the Life Course: Three Case Studies

The causes and contexts of food insecurity among children in the U.S. are poorly understood because the prevalence of food insecurity at the child level is low compared to the prevalence of household food insecurity. In addition, caregivers may be reluctant to admit their children may not be getting enough food due to shame or fear they might lose custody of their children. Based on our ongoing qualitative research with mothers of young children, we suggest that food security among children is related to adverse childhood experiences of caregivers. This translates into poor mental and physical health in adolescence and adulthood, which can lead to inability to secure and maintain meaningful employment that pays a living wage. In this paper we propose that researchers shift the framework for understanding food insecurity in the United States to adopt a life course approach. This demands we pay greater attention to the lifelong consequences of exposure to trauma or toxic stress—exposure to violence, rape, abuse and neglect, and housing, food, and other forms of deprivation—during childhood. We then describe three case studies of women from our ongoing study to describe a variety of toxic stress exposures and how they have an impact on a woman’s earning potential, her mental health, and attitudes toward raising children. Each woman describes her exposure to violence and deprivation as a child and adolescent, describes experiences with child hunger, and explains how her experiences have shaped her ability to nourish her children. We describe ways in which we can shift the nature of research investigations on food insecurity, and provide recommendations for policy-oriented solutions regarding income support programs, early intervention programs, child and adult mental health services, and violence prevention programs.

Access to parental leave in Australia: evidence from Negotiating the Life Course

Although unpaid parental leave has been available to most Australian employees for more than a decade, and public sector legislation and company policies provide at least some employees with an entitlement to paid parental leave, there is as yet little information available on accessibility, take-up rates or the extent to which current leave provisions meet the needs of parents. In this paper, data from the Negotiating the Life Course survey are used to examine the first of these issues: accessibility. Variations in perceptions of access to paid and unpaid parental leave are examined in bivariate and multivariate analyses, which emphasise marked divisions in the Australian labour market between permanent and casual status. The data also suggest that access to unpaid parental leave is more variable than might be expected from a reading of formal legislative provisions, and raise questions over the accessibility of paid parental leave to those who need it most-employees with young children.
