Applying socio-cultural lenses to childhood obesity prevention among African migrants to high-income western countries : the role of acculturation, parenting and family functioning

Migration from third-world and low-income countries to high-income Western countries presents significant challenges for individuals and families, and for health service providers in the receiving societies. Cultural conflicts related to preferred body size/shape and parenting practices, together with differential inter generational rates and styles of acculturation, can affect nutritional and lifestyle choices and be associated with high rates of childhood obesity. Using African cultures as an example, this paper examines these issues. It concludes that, in designing and implementating obesity prevention programmes, health service providers need to understand these factors and how they play out.

How is men's conformity to masculine norms related to their body image? Masculinity and muscularity across western countries

Previous research has suggested that men's conformity to masculine norms (CMN) is an important correlate of men's drive for muscularity. The present study aimed to further delineate the relationship between masculinity and men's body image by examining various dimensions of CMN in relation to various dimensions of men's body image (muscularity, leanness, and fitness) in a cross-national sample. Participants comprised young men from the United States (n = 192), the United Kingdom (n = 141), Australia (n = 160), and Sweden (n = 142). Multigroup path analyses showed that CMN was related to drive for muscularity, leanness, and fitness in all 4 countries, but there were differences across countries in which dimensions of CMN predicted men's body image. Whereas conformity to the masculine norm of winning was a salient predictor across the 4 countries, conformity to the norm of risk-taking was linked to Australian men's body image, and conformity to the norm of violence to British men's body image. The findings support previous research suggesting that men's endorsement of the male gender role plays a significant role in their desire for an ideal body, but the results uniquely document that this relationship may differ across countries.

Migrants getting fat in Australia: acculturation and its effects on the nutrition and physical activity of African migrants to developed countries

Obesity is a significant health problem in Australia and other developed countries and acculturation is one fo the many risk factors. This new book summarizes acculturation and anthropometric outcomes among sub-Saharan African migrants in Australia. The book further examines the relationship between acculturation and food, energy and nutrient intake and physical activity. Some policy recommendations are proposed.

Assessing the economic benefits of starling detection and control to Western Australia

The common starling (Sturnus vulgaris) has a proven invasion history in many countries, and at a continental scale in North America and Australasia. In Australia, starlings are firmly established throughout the eastern states and Tasmania. Incursions of starlings into Western Australia (WA) represent a significant threat to this State’s agricultural, public amenity and biodiversity assets. We present models of starling population dynamics that incorporate environmental and control effort variability. We incorporate knowledge of starling ecology with economic data to assess the potential economic cost of starlings establishing in WA, evaluating the cost–benefits for each management scenario. We calculated starling population size will approach carrying capacity in WA within as little as 30 years if left unchecked. A population of this size could cost the WA economy up to $43.7 million annually in 2011/2012 dollars. Over a 50 year horizon, the conservative benefit–cost ratio for ongoing detection and control at the current level of expenditure is 6.03:1. However, even under current levels of control, starling numbers are projected to increase to almost 11 million by 2061. Further improvements in the efficiency of starling detection and control and/or an increased level of expenditure on detection and control are required.

Institutional economics approach to irrigation management with special reference to developing countries

Neoclassical economics has failed to address irrigation management issues in developing countries successfully. Institutions are at the heart some of these failures. Many academics in various disciplines in the social sciences now emphasize the need to pay attention to the multitude of informal institutions such as rotational irrigation in developing countries and not to treat them as irrelevant for development. Water user associations have been initiated for irrigation management in many countries. These have shown much promise although many problems still constrain the full adoption of this institutional mode. Water pricing is still at its infancy and significant problems remain in the use of the market system for improved management of irrigation water.

Effectiveness of prevention programmes for obesity and chronic diseases amongst immigrants to developed countries - a systematic review

Objective: To determine whether interventions tailored specifically to  particular immigrant groups from developing to developed countries  decrease the risk of obesity and obesity-related diseases.

Design: Databases searched were MEDLINE (1966–September 2008), CINAHL (1982–September 2008) and PsychINFO (1960–September 2008), as well as Sociological Abstracts, PsychARTICLES, Science Direct, Web of Knowledge and Google Scholar. Studies were included if they were randomised control trials, ‘quasi-randomised’ trials or controlled before-and-after studies. Due to the heterogeneity of study characteristics only a narrative synthesis was undertaken, describing the target population, type and reported impact of the intervention and the effect size.

Results: Thirteen studies met the inclusion criteria. Ten out of thirteen (77 %) studies focused on diabetes, seven (70 %) of which showed significant improvement in addressing diabetes-related behaviours and glycaemic control. The effect on diabetes was greater in culturally tailored and facilitated interventions that encompassed multiple strategies. Six out of the thirteen studies (46 %) incorporated anthropometric data, physical activity and healthy eating as ways to minimise weight gain and diabetes-related outcomes. Of the six interventions that included anthropometric data, only two (33 %) reported improvement in BMI Z-scores, total skinfold thickness or proportion of body fat. Only one in three (33 %) of the studies that included cardiovascular risk factors reported improvement in diastolic blood pressure after adjusting for baseline characteristics. All studies, except four, were of poor quality (small sample size, poor internal consistency of scale, not controlling for baseline characteristics).

Conclusions: Due to the small number of studies included in the present review, the findings that culturally tailored and facilitated interventions produce better outcomes than generalised interventions, and that intervention content is more important than the duration or venue, require further investigation.

Macroeconomic impact of foreign aid to developing countries

The thesis looks at the macroeconomic impact of foreign aid. It is specially concerned with aid's impact on the public sector of less developed countries < LDCs> . Since the overwhelming majority of aid is directed to the public sector of LDCs, one can only understand the broader macroeconomic impact of aid if one first understands its impact on this sector. To this end, the thesis econometrically estimates " fiscal response" models of aid. These models, in essence, attempt to shed light on public sector fiscal behaviour in the presence of aid inflows, being specially concerned with the way aid is used to finance various categories of expenditures. The underlaying concern is to extent to which aid is " fungible" -that is, whether it finances consumption expenditure and reductions in taxation revenue in LDCs. A number of alternative models are derived from a utility maximisation framework. These alternatives reflect different assumptions regarding the behaviour of LDC public sectors and relate to the endogeniety to exogeniety> of aid, whether or not recurrent expenditure is financed from domestic borrowing and the determination of domestic borrowing. The original frameworks of earlier studies are extended in a number of ways, including the use of a public sector utility function which is fully consistent with expected maximising behaviour. Estimates of these models' parameters are obtained using both time-series and cross-section data, dating from the 1960s, for Bangladesh, India, Pakistan and the Philippines. Both structural and reduced-form equations are estimated. Results suggest that foreign aid to the official sector> is indeed fungible, albeit at different levels. Moreover, the overall impact of aid on public sector investment, consumption, domestic borrowing and taxation varies between countries. Generally speaking, aid leads to increases in investment and consumption expenditure, but reduces taxation and domestic borrowing. Comparative analysis does, however, show that these results are highly sensitive to alternative behavioural assumptions and, therefore, model specification.
