Abstract
This study was conducted to examine changes in coffee intake according to the sociodemographic characteristics of the people over 50 and the elderly living in Korea. The data of 2,316 and 3,170 people were extracted respectively from the 2001 and 2011 Korea National Health and Nutrition Examination Surveys. The data were analyzed by gender, age, region area, marital status, educational level, household income, economic activity, and subjective health status. They were also analyzed according to gender and age by average daily intake of coffee, coffee type, place, cups of coffee a day and amount of coffee intake per serving. All statistical analyses were performed with IBM PASW Statistics (SPSS) 21.0 which is capable of complex sample design by frequency analysis, chi-square test, t-test, and logistic regression analysis. The results of the study showed that coffee consumption of the elderly was influenced by their economic activity. In 2011, elderly men ingested averagely more coffee than elderly women, and they also consumed brewed coffee mostly at workplace. Moreover, age groups of over 75 tended to consume a lot of brewed coffee. In this respect, the coffee industry should be aware of the elderly as a new consumption group. Also, this study provides a variety of coffee shops with basic data for product development and marketing activities.
