Abstract

Systemic exposure to cigarette smoke adversely affects the metabolism of vitamin D. An individual's understanding of smoking can significantly shape their attitude towards it. This study sought to explore the correlation between knowledge and attitudes regarding vitamin D levels among active smokers. This cross-sectional research was conducted in the Mejoyo area, in April-July 2023. Respondents were male active smokers who completed the questionnaire and do not have allergies to fish, eggs and milk, by using a purposive sampling technique. Respondents were asked to provide complete demographic data, and fill out a knowledge and attitude questionnaire, as well as a vitamin D status questionnaire. The relationship between knowledge, attitudes and vitamin D status was tested using chi-square tests with p<0.05 as significant. The total number of respondents was 124 people. Most respondents had low level of knowledge (82.40%) and medium attitude level (92.80%). The risk of vitamin D deficiency was 54.80% and no risk of vitamin D deficiency was 45.20%. With the chi-square test, there was no significant relationship between knowledge (p=0.173) and attitude (p=0.960) related to vitamin D and the risk of vitamin D deficiency. Therefore, further research is needed on the factors that influence vitamin D by increasing knowledge and attitudes.
