Determinants of health prevention behaviors in Portugal

Abstract Background One of the main causes of death in developed societies are chronic non-communicable diseases, often originated by risky behaviors as tobacco consumption, poor diet, excessive alcohol consumption and lack of physical activity. Changing lifestyles can thus lead to a reduction in chronic diseases and in their economic costs. The objective of this study is to understand what the main factors associated with health behaviors are. Methods We used the data collected through the Portuguese National Health Surveys from 2014 and 2019. The sample analyzed was composed of individuals aged 15 or more years old living in the national territory at the time the surveys were conducted. Data on demographics, socio-economic variables and health related variables was used. A maximum likelihood estimation was performed using a multivariate probit model, by using health behaviors (weekly exercise, healthy diet, non-smoking, and prudent alcohol consumption) as the outcomes of the analysis. Results The results point to a strong association between social class and health behaviors, particularly between higher income and healthy diet. It is important to highlight that having an appointment with a General Practitioner is positively associated with all healthy behaviors. For all behaviors but healthy diet, the coefficients are statistically significant at a 5% significance level and non-smoking displays the highest one (0.135). Conclusions This study presents the first step to understand the determinants of health prevention behaviors, which is important to design policies targeting lifestyles. One of its main conclusions indicates that social class (income and education) and GP appointments are associated with health behaviors. Further research would be needed to study the underlying mechanisms through which some of these factors impact behaviors. This presentation was supported by National Funds through FCT, I.P., within CINTESIS, R&D Unit (reference UIDB/4255/2020). Key messages • This study is an important step in the formulation of policies targeting lifestyles since it allows us to understand which factors are associated with health behaviors. • From this study one can conclude that social class characteristics, particularly income, and access to GP appointments are associated positively with health behaviors.
