Background: Most people with dementia live in low- and middle-income countries and little is known about the potential for reducing these numbers by reducing key risk factors.Objective: To investigate the potential for dementia incidence reduction in Brazil, Mozambique, and Portugal (a culturally related, high-income country).Methods: We replicated previously published methods and based on the relative risks from previous studies, we estimated the population-attributable risk (PAR) of dementia in Mozambique, Brazil, and Portugal for seven modifiable risk factors associated with dementia (low educational attainment, physical inactivity, midlife hypertension, midlife obesity, depression, smoking, and diabetes mellitus). The combined PAR was calculated and adjusted for associations between risk factors. The potential for risk factor reduction was assessed by examining the effect of relative reductions of 10% and 20% per decade for each of the risk factors on projections for dementia cases for each decade until 2050.Results: After adjusting for non-independence of risk factors, 24.4%, 32.3%, and 40.1% of dementia cases could be related to seven potentially modifiable risk factors in Mozambique, Brazil, and Portugal, respectively. Reducing the prevalence of each risk factor by 20% per decade could, by 2050, potentially reduce the prevalence of dementia in Mozambique, Brazil, and Portugal by 12.9%, 16.2%, and 19.5%, respectively.Conclusion: There is a substantial difference between the countries in the percentage of dementia cases that could be attributable to the seven potentially modifiable risk factors. The proportion of cases that could be prevented by 2050 if measures were taken to address these main risk factors was higher in Portugal than in Brazil and Mozambique. Each country or region should consider their unique risk factor profile when developing dementia risk reduction programs. [ABSTRACT FROM AUTHOR]

With a worldwide increase in disasters, the effects of climate change are already being felt, and it is the urban poor in developing countries who are most at risk. There is an urgent need to better understand the factors that determine people's capacity to cope with and adapt to adverse climate conditions. This paper examines the influence of formal education in determining the adaptive capacity of the residents of two low-income settlements: Los Manantiales in San Salvador (El Salvador) and Rocinha in Rio de Janeiro (Brazil), where climate-related disasters are recurrent. In both case study areas, it was found that the average levels of education were lower for households living at high risk, as opposed to residents of lower risk areas. In this context, the influence of people's level of education was identified to be twofold due to (a) its direct effect on aspects that reduce risk, and (b) its mitigating effect on aspects that increase risk. The results further suggest that education plays a more determinant role for women than for men in relation to their capacity to adapt. In light of these results, the limited effectiveness of institutional support identified by this study might also relate to the fact that the role of formal education has so far not been sufficiently explored. Promoting (improved access to and quality of) formal education as a way to increase people's adaptive capacity is further supported with respect to the negative effects of disasters on people's level of education, which in turn reduce their adaptive capacity, resulting in a vicious circle of increasing risk.
