Research Capacity for Prevention and Control of Non-communicable Diseases and their Risk Factors in Nepal: Findings of a Needs Assessment Study.

Background Despite a high burden, there are limited trainings in non-communicable disease research in Nepal. Objective We conducted a needs assessment to assess existing research training capacity in academic health institutions of Nepal for the prevention and control of noncommunicable diseases, identify gaps in research, and explore the feasibility of developing research training program in Nepal targeting non-communicable diseases. Method We did mixed-method research and reviewed academic institution curricula and scientific articles authored by Nepali researchers. We conducted 14 Focus Group Discussions with bachelor and masters level students of public health and community medicine; 25 In-depth Interviews with department heads and faculties, and government stakeholders. We surveyed medical and public health students on their research knowledge and skills development. Result Research methodology component was addressed differently across academic programs. One-third (33.7%) of students expressed lack of skills for analysis and interpretation of data. They felt that there is a wide scope and career-interest in non-communicable diseases research in Nepal. However, specific objectives in the curriculum and practical aspects regarding non-communicable diseases were lacking. Most of the non-communicable diseases research in Nepal are prevalence studies. Lack of funding, conflicting priorities with curative services, and inadequate training for advanced research tools were reported as major barriers. Conclusion Nepal must strengthen the whole spectrum of research capacity: epidemiological skills, research management, and fund development. Generation of a critical mass of non-communicable disease researchers must go together with improved funding from the government, non-governmental, and external funding organizations.

Estimating the global and regional burden of suboptimal nutrition on chronic disease: methods and inputs to the analysis.

BACKGROUND/OBJECTIVES: Global burdens of cardiovascular disease (CVD), diabetes and cancer are on the rise. Little quantitative data are available on the global impact of diet on these conditions. The objective of this study was to develop systematic and comparable methods to quantitatively assess the impact of suboptimal dietary habits on CVD, diabetes and cancer burdens globally and in 21 world regions. SUBJECTS/METHODS: Using a comparative risk assessment framework, we developed methods to establish for selected dietary risk factors the effect sizes of probable or convincing causal diet-disease relationships, the alternative minimum-risk exposure distributions and the exposure distributions. These inputs, together with disease-specific mortality rates, allow computation of the numbers of events attributable to each dietary factor. RESULTS: Using World Health Organization and similar evidence criteria for convincing/probable causal effects, we identified 14 potential diet-disease relationships. Effect sizes and ranges of uncertainty will be derived from systematic reviews and meta-analyses of trials or high-quality observational studies. Alternative minimum-risk distributions were identified based on amounts corresponding to the lowest disease rates in populations. Optimal and alternative definitions for each exposure were established based on the data used to quantify harmful or protective effects. We developed methods for identifying and obtaining data from nationally representative surveys. A ranking scale was developed to assess survey quality and validity of dietary assessment methods. Multi-level hierarchical models will be developed to impute missing data. CONCLUSIONS: These new methods will allow, for the first time, assessment of the global impact of specific dietary factors on chronic disease mortality. Such global assessment is not only possible but is also imperative for priority setting and policy making.
