The Effect of Smoking Habit on Vitamin D Status of Adults in Indonesia

Abstract

Abstract Smoking will reduce the metabolism of vitamin d in the body. Indonesia, as a tropical country that has a high level of sun exposure, is one with a high prevalence of smokers. Early identification of vitamin D status can be used as a preventive measure for risks associated with vitamin D deficiency. This study aimed to determine smoking behavior with vitamin D status. This research was conducted in April -November 2021. The research design was cross-sectional, using a purposive sampling method. Variables were smoker behavior, vitamin D status, and vitamin D deficiency. The differences between vitamin D status and smoker behavior in the smoker and non-smoker group used the chi-square test and the relationship used the contingency coefficient. This study involved 144 subjects, consisting of 73 non-smokers and 71 smokers. The groups at risk for vitamin D deficiency were 17 non-smokers (23.29%) and 31 smokers (43.66%). The smokers’ group had a 2,553 times higher risk of vitamin D deficiency than non-smokers. There was a significant difference between smokers and non-smokers on 25(OH)D level vitamin D status. There was a significant relationship between vitamin D status in smokers and non-smokers. There was a weak relationship between smokers and non-smokers on vitamin D status.
