'Tobacco and alcohol use are playing critical role in the interaction of social determinants of non-communicable diseases in Nepal': a systems perspective

Abstract

Background: Tobacco and alcohol use are major behavioural risks in developing countries like Nepal contributing to rapid increase in non-communicable diseases (NCDs). This causal relationship is further complicated by the multi-level social determinants such as socio-political context, socio-economic factors and health system. Systems approach has potential to facilitate understanding of such complex causal mechanism. The objective of this paper was to describe the role of tobacco and alcohol use in the interaction of social determinants of NCDs in Nepal. Method: The study was a qualitative study design guided by the Systemic Intervention methodology. The study involved key informant interviews (n=63) and focus group discussions (n-12) at different levels (policy, district and/or community) and was informed by the adapted Social Determinants of Health Framework . The data analysis involved case study based thematic analysis using framework approach and development of causal loop diagram. The study also involved three sense making sessions with key stakeholders. Results: Five key interacting themes emerged during the data analysis. Habit and misconception relating to alcohol and tobacco use contributed to the use and addiction of tobacco and alcohol. Low focus on prevention by health system further contributed to the problem. Decline in community capital and gendered social constructs influenced tobacco and alcohol use. Socio-economic status of families/communities was discussed as a potential root cause of use and addiction of tobacco and alcohol. These interacting themes were utilized to develop iterative causal loop diagrams showing the influence of tobacco and alcohol use in the interaction of social determinants of NCDs in Nepal. Conclusion: Tobacco and alcohol use and addiction causally linked broader social determinants (social, economic and political) to NCD in the context of Nepal. These CLDs showed how socio-economic circumstances was influencing addiction and availability of tobacco and alcohol products in Nepal. A multi-sectoral response led by health system is urgently needed.
