Help or hindrance? Social policy and the ‘social determinants of health’

In recent years, public health research has become increasingly focused on issues of social inequality and social disadvantage. This is because social issues, such as poor housing and unemployment, have been found to impact health significantly, and are now referred to as ‘the social determinants of health‘. As a result of this shift, public health is now principally concerned with what are historically considered to be social policy issues. This paper discusses the confluence of public health and social policy; it examines the opportunities and risks posed by this convergence for those working in social policy seeking to reduce poverty and inequality. We argue that, while much can be gained in the two fields by working more closely together, there remain fundamental differences in perspectives and approaches. In order to maximise benefits, these points of difference need to be thought through sooner rather than later.     

Revising the standard wisdom of C. elegans natural history: ecology of longevity

Here, we consider that most of the research concerning Caenorhabditis elegans has been laboratory focused and that only limited research has directly considered the worm's biology relative to its natural history in the wild. We describe that, although the worm has traditionally been considered a soil nematode, we could not find it in soil but frequently recovered it from snails. Finally, we discuss how a better understanding of the natural history of C. elegans may enhance its usefulness as a model organism for studying aging and other phenomena.     

Using satellite remote sensing and household survey data to assess human health and nutrition response to environmental change

Climate change and degradation of ecosystem services functioning may threaten the ability of current agricultural systems to keep up with demand for adequate and inexpensive food and for clean water, waste disposal and other broader ecosystem services. Human health is likely to be affected by changes occurring across multiple geographic and time scales. Impacts range from increasing transmissibility and the range of vectorborne diseases, such as malaria and yellow fever, to undermining nutrition through deleterious impacts on food production and concomitant increases in food prices. This paper uses case studies to describe methods that make use of satellite remote sensing and Demographic and Health Survey data to better understand individual-level human health and nutrition outcomes. By bringing these diverse datasets together, the connection between environmental change and human health outcomes can be described through new research and analysis.     

Knowledge and education for peoples’ sovereignty

ABSTRACT

Living examples of peoples’ sovereignty can illustrate the path toward positive people-centred alternatives to control by the capitalist State, wealthy private land-owners and corporations. Efforts to undermine Indigenous and other peoples’ sovereignty have been deliberate and continue to take place in industrialized and ‘developing’ countries. Yet peoples’ sovereignty has the capacity to unite and educate people in important ways. Many examples of education to promote peoples’ sovereignty are emerging, building on the knowledge that communities have generated over time. This is a very different educational model than the one most commonly recognized and implemented in industrialized societies. People working in higher education everywhere have the responsibility to educate our students about the history of colonization and destruction of peoples’ sovereignty, so that they understand the real history of their countries, to build alliances with other educators globally, and to form bonds of solidarity with peoples’ movements.     

The Impact of Paternity and Marital Status on Low Birth Weight and Preterm Births

In the United States the number of births to unmarried mothers is at a record high. Although being unmarried is a significant risk factor for low birth weight and preterm births, paternal presence may have a protective effect. In addition to marital status, paternity may be a proxy measure for paternal support. Virginia birth registry data were analyzed to investigate the effect of marital and paternity status on low birth weight and preterm births. Findings from this study show that women who reported being unmarried and with no paternity status were 1.6 (odds ratio = 1.57, 95% confidence interval = 1.41–1.75) and 1.4 (odds ratio = 1.39, 95% confidence interval = 1.21–1.61) times more likely to have preterm low birth weight and term low birth weight babies, respectively. Being unmarried and lack of established paternity appear to be significantly correlated with and may be important risk factors for preterm and low birth weight deliveries. Health care professionals should be aware of the potential role of paternal presence and marital status may play with respect to preterm births and low birth weight.
