perception of lay people regarding determinants of health and factors affecting it: an aggregated analysis from 29 countries

background: this study aimed to evaluate the perception of lay people regarding determinants of health at global level and factors affecting it. methods: data was collected from international social survey program (issp) and world bank website. multilevel regression analysis was done and lay people’s perception regarding health behavior, environment, poverty and genes as health determinants was assessed. various socio demographic factors were used as independent variables. results: the highest percentage of people agreed environment as determinant of health. an inverse relationship was observed between gni quartiles and an individual’s agreement with poverty, health behavior, and environment as health determinant. there was a significant negative association of females with health damaging behavior ( p <0.05) and positive association with environment and genes ( p <0.05) as health determinants. elderly people agreed with poverty as determinant of health ( p <0.05). gni was negatively related to environment ( p <0.05) and poverty ( p <0.05) as health determinant. conclusion: the common public is now becoming aware of a broadened concept of health and people belonging to different backgrounds have different perceptions regarding determinants of health. our results show that highest percentage of people agreed with environment as determinant of health, which is consistent with scientific view of increased burden of disease, caused by environmental factors. thus, tailored health programs and policies that address an individual's specific problems are likely to induce a change in behavior and attitude, hence decreasing the disease burden. eywords: issp, determinants of health, multilevel analysis, tailored approach
