Analysis of the effect of smoking and exercise habits on coronary heart disease in Indonesia using logistic regression

The high number of people with coronary heart disease (CHD) is comparable to the high level of smoking in Indonesia. The Indonesian's lack of physical activity pattern, based on Basic Health Research (Riskesdas) results in 2018, rose from 26.1% to 33.5%. The incidence of CHD in Indonesia is potentially increasing. The study aims to analyze the effects of smoking and exercise habits on the incidence of CHD using data from the fifth wave of Indonesian Family Life Survey (IFLS 5). The binary logistic regression model was used to explain the factors affecting whether a respondent has CHD or not. The results showed that the smoking habit, age, hypertension, and high cholesterol were significant predictors for the incidence of CHD (yes or no) in Indonesia. The exercise habits, gender and education were not significant predictors for the incidence of CHD in Indonesia. The main result found that the CHD in Indonesia is 1.898 times more likely to occur among people who smoke than non-smokers.
