Child Mortality and Socioeconomic Status: An Examination of Differentials by Migration Status in South Africa1

INTERNATIONAL MIGRATION REVIEW, Issue 1 2007
Kevin J. A. Thomas
This study examines child mortality and socioeconomic status among migrants and nonmigrants. It also examines child mortality by migration status in all quintiles of socioeconomic status, comparing immigrants to the native-born and internal migrants to nonmigrants. The results show that among migrants, child mortality decreased faster as socioeconomic status increased than among nonmigrants. The results also show a cross-over in the likelihood of child mortality by immigration status as socioeconomic status increased. In the poorest socioeconomic quintiles immigrants had a greater likelihood of child mortality than the native-born while in the wealthiest quintiles child mortality was greater among the native-born.

Plasticity in vertical behaviour of migrating juvenile southern bluefin tuna (Thunnus maccoyii) in relation to oceanography of the south Indian Ocean

FISHERIES OCEANOGRAPHY, Issue 4 2009
SOPHIE BESTLEY
Abstract Electronic tagging provides unprecedented information on the habitat use and behaviour of highly migratory marine predators, but few analyses have developed quantitative links between animal behaviour and their oceanographic context. In this paper we use archival tag data from juvenile southern bluefin tuna (Thunnus maccoyii, SBT) to (i) develop a novel approach characterising the oceanographic habitats used throughout an annual migration cycle on the basis of water column structure (i.e., temperature-at-depth data from tags), and (ii) model how the vertical behaviour of SBT altered in relation to habitat type and other factors. Using this approach, we identified eight habitat types occupied by juvenile SBT between the southern margin of the subtropical gyre and the northern edge of the Subantarctic Front in the south Indian Ocean. Although a high degree of variability was evident both within and between fish, mixed-effect models identified consistent behavioural responses to habitat, lunar phase, migration status and diel period. Our results indicate SBT do not act to maintain preferred depth or temperature ranges, but rather show highly plastic behaviours in response to changes in their environment. This plasticity is discussed in terms of the potential proximate causes (physiological, ecological) and with reference to the challenges posed for habitat-based standardisation of fishery data used in stock assessments.

VARYING EFFECT OF FERTILITY DETERMINANTS AMONG MIGRANT AND INDIGENOUS FEMALES IN THE TRANSITIONAL AGRO-ECOLOGICAL ZONE OF GHANA

Samuel Nii Ardey Codjoe
ABSTRACT. The transitional agro-ecological zone of Ghana, located between the richly endowed south and the impoverished north, has attracted seasonal and permanent farm migrants, mainly from northern Ghana, who now live side by side with the indigenous people. While migrants have higher numbers of Muslims, indigenous people are mainly Christians. Although the majority of the migrants live in migrant quarters with less favourable socio-economic conditions, they are more successful farmers and therefore wealthier. The objectives are to examine the varying effect of fertility determinants among migrants and indigenous females. This paper uses data collected in 2002 among 194 females aged 15 to 49 years. Multiple regression models are used to assess fertility determinants. Results show that although migrant households were wealthier, migrant females were more traditional. They had more children living in foster care, and a lower proportion of them approved of men participating in household activities. In addition, they were less well educated, recorded higher infant mortality, gave birth earlier and used less contraception. Furthermore, while a female's migration status is statistically significant so far as non-proximate determinants of fertility are concerned, the same variable is not significant with respect to proximate determinants. In addition, a married female migrant would on average have almost one more child compared to her indigenous counterpart, and migrant females who had experienced the loss of a child would on average have 2.5 more children compared to their indigenous counterparts. Finally, more affluent migrant females have 0.08 fewer children compared to their indigenous counterpart. [source]

Australian asylum policies: have they violated the right to health of asylum seekers?

AUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 1 2009
Vanessa Johnston
Abstract Objectives: Notwithstanding recent migration policy amendments, there is concern that Australian asylum policies have disproportionately burdened the health and wellbeing of onshore asylum seekers. There may be a case to be made that Australian governments have been in violation of the right to health of this population. The objective of this paper is to critically examine these issues and assess the implications for public health practice. Methods:The author undertook a review of the recent empirical literature on the health effects of post-migration stressors arising from Australian policies of immigration detention, temporary protection and the restriction of Medicare to some asylum seekers. This evidence was examined within the context of Australia's international law obligations. Results: Findings reveal that Australian asylum policies of detention, temporary protection and the exclusion of some asylum seekers from Medicare rights have been associated with adverse mental health outcomes for this population. This is attributable to the impact of these policies on accessing health care and the underlying determinants of health for aslyum seekers. Conclusion: It is arguable that Australian Governments have been discriminating against asylum seekers by withholding access on the grounds of their migration status, to health care and to the core determinants of health in this context. In so doing, Australia may have been in violation of its obligation to respect the right to health of this population. Implications: While the ,right to health' framework has much to offer public health, it is an undervalued and poorly understood discipline. The author argues for more education, research and advocacy around the intersection between heath and human rights. [source]

Demographic, migration status, and work-related changes in Asian female sex workers surveyed in Sydney, 1993 and 2003

AUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 2 2006

Objective: To compare demography, sexual health awareness, migration and workplace conditions of Asian female sex workers in Sydney in 1993 and 2003. Method: A Chinese interpreter and a Thaispeaking health education officer (HEO) were used to administer a questionnaire survey to Thai- and Chinese-speaking sex workers attending sexual health clinics in 1993. A follow-up survey, which included some women contacted at work as well as clinic attenders, was administered by Thai-and Chinese-speaking HEOs in 2003. Results: Ninety-one female sex workers were surveyed in 1993 and 165 in 2003. Median age increased (26 years vs. 33 years, p=0.000), as did numbers of Chinese- versus Thai-speakers (1993, 25.3% Chinese vs. 2003, 58.2% Chinese, p=0.000). In 2003, the women reported more years of schooling and better English skills. Fewer reported previous sex work (48.4% vs. 17.6%, p=0.000). Numbers currently or ever on a contract decreased sharply (27.5% vs. 9.1%, p=0.000) and the majority were apparently working legally. Condom use at work for vaginal (51.6% vs. 84.8%) and oral sex (39.6% vs. 66.1%) increased significantly (p=0.001). Chinese-speaking sex workers were less informed about HIV transmission and safer sex practices than were Thai sex workers. Drug and alcohol use was low. Conclusions and Implications: Positive changes have occurred in the conditions of Asian female sex workers surveyed over 10 years in Sydney. Maintaining current levels of health service delivery will ensure continued improvements in health and workplace conditions and address inequalities between language groups. [source]
