Experiences and needs of licensed health risk assessors conducting health impact assessment in the Czech Republic.

OBJECTIVE: The main aim of this study is to discover and analyse the utilization of health impact assessment (HIA) among HIA certificate holders, and to ascertain their opinions on the current situation in the Czech Republic and on the possible future nationwide implementation of health impact assessment. METHODS: The target group of the research was identified as holders of professional competence certificates in the field of public health impact assessment. A structured questionnaire was developed. The first part mapped the recent use of HIA in the Czech Republic, the second addressed the issue of linking HIA to regional policies and to the national strategy, the third aimed to gain information about the preparedness of the Czech Republic for the full implementation of HIA, and the last part focused on quality assessment and capacity building for HIA. RESULTS: The results of the survey point to the inconsistencies in the perception of the whole concept of HIA in the Czech Republic by the professional public, and also to a shortage of experts in this area. There is only a narrow circle of experts, especially in the field of health care. It also lacks an informational base, which assist in the unification of processes in this area. As the results of the questionnaire showed, the problems are the lack of interest in the application of the HIA method and, subsequently, the lack of demand. CONCLUSION: The collected data showed obstacles and gaps in the implementation of the HIA methodology in the Czech Republic. At the same time it has revealed possible ways to change the current situation, based on the opinions of those who practice this methodology in the Czech Republic.

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.
