The call to action: health promotion in The Gambia - closing the implementation gap?

Analysis of main risk factors contributing to obesity in the region of East Africa: meta-analysis

Background

Over a few decades obesity has become a major global health problem. Its prevalence worldwide has more than doubled since 1980. The situation is expected to worsen in the future, especially in the developing countries that experience nutrition transition due to economic growth. It contributes to reduction in malnutrition which supports an increase in obesity prevalence.

Objectives

The aim of this study was to analyse the predictors of obesity in the region of East Africa.

Methods

Meta-analysis of existing studies was used in order to find the different risk factors and their significance in obesity development. Data extracted from 16 published academic research articles described the situation in East African countries. The significance of the effect of each variable was tested by means of an asymptotic chi-square test, or Fisher's exact (factorial) test and the risk ratios were calculated.

Results

Based on the chi-square test and the risk ratios of the aggregated data, three risk factors were found to be significant in the development of obesity – gender, type of residence and socio-economic status. In East African countries, women are significantly more likely to be obese. Living in an urban area and socioeconomic status are also positively associated with obesity. Because of insufficient data three other risk factors did not prove to be of any significance – alcohol consumption, smoking and education level.

Conclusion

Conclusions of this meta-analysis confirm world trends but we also found results that are not in line with them (e.g. education). This meta-analysis confirms the huge existing research gap concerning obesity predictors in the East African region.

A rollercoaster of policy shifts: global trends and reproductive health policy in The Gambia

Global trends influence strategies for health-care delivery in low- and middle-income countries. A drive towards uniformity in the design and delivery of healthcare interventions, rather than solid local adaptations, has come to dominate global health policies. This study is a participatory longitudinal study of how one country in West Africa, The Gambia, has responded to global health policy trends in maternal and reproductive health, based on the authors' experience working as a public health researcher within The Gambia over two decades. The paper demonstrates that though the health system is built largely upon the principles of a decentralised and governed primary care system, as delineated in the Alma-Ata Declaration, the more recent policies of The Global Fund to Fight HIV/AIDS, Tuberculosis, and Malaria and the GAVI Alliance have had a major influence on local policies. Vertically designed health programmes have not been easily integrated with the existing system, and priorities have been shifted according to shifting donor streams. Local absorptive capacity has been undermined and inequalities exacerbated within the system. This paper problematises national actors' lack of ability to manoeuvre within this policy context. The authors' observations of the consequences in the field over time evoke many questions that warrant discussion, especially regarding the tension between local state autonomy and the donor-driven trend towards uniformity and top-down priority setting.
