Diet variety is associated with socio-economic factors

This study examines the relationship between diet variety and socio-economic factors. The analysis included a 24-h recall and measures of socio-economic status from 6545 Koreans aged >= 19. Three variety measures (VM), including two diet variety scores were calculated. The more highly educated consumed a greater variety of foods than the less educated. Results suggest that VM increases faster among less educated when income increases. In summary, the diet variety of Koreans depends on their income, education, and area of residence. Among the less educated, diet variety depends more on income than it does among higher educated. Health implications of dietary variety consumed in Korea requires further attention.
