The Association between Smoking, Alcohol Intake, and Low-Salt Diet: Results from the 2008 Community Health Survey

Abstract

ABSTRACT The purpose of this study was to identify the association between health-related behaviors including smok-ing, alcohol intake, and the practice of a low-salt diet using data from a Community Health Survey conducted in 2008. The study subjects were 129,151 persons (19 years and older) without cardiovascular diseases or dia-betes mellitus diagnosis history. An index for evaluating low salinity was created by summing three low sal-inity-related questions (range: 0∼3), and a low-salt diet was defined if the index of low salinity was 3. We examined the levels of smoking and alcohol intake according to the index of low salinity, and conducted multiple logistic regression analysis to examine the odds ratios of low-salt diet practice in relation to smoking and drinking behavior, adjusting for general characteristics. The smoking and drinking status significantly im-proved as the level of low salinity index increase. Adjusting for general characteristics, those with smoking, alcohol intake, or a combined habit of the two behaviors had significantly lower odds ratios for practice of a low-salt diet. In conclusion, smoking and drinking behavior were negatively associated with the practice of a low-salt diet. Based on these findings, it may be necessary to have comprehensive nutritional education pro-grams that consider the multiple effects of smoking, drinking, and a low-salt diet.
