AbstractOBJECTIVES
This study was conducted to examine the differences in food literacy between adults and older adults and the association of food literacy with food group intake.METHODSIn total, 4,039 participants from the 2021 Survey for Food Consumption in Seoul were included in this study. The intake of whole grains, high-protein foods, total vegetables, vegetables excluding kimchi and pickles, fresh fruits, and milk and dairy products was assessed using a simple food frequency questionnaire. Food literacy was measured using a food literacy measurement questionnaire.RESULTSWith the exception of milk and dairy, adults had a significantly higher proportion of insufficient food intake than older adults (p<0.001). Both adults and older adults with sufficient food group consumption had higher food literacy scores. Notably, the difference in food literacy scores by level of food intake was highest for fresh fruits (p<0.001). After adjusting for confounding factors affecting food literacy scores, a higher score was associated with a lower probability of having insufficient food intake in all food groups for both adults and older adults. Specifically, those in the highest food literacy score quartile were less likely to have insufficient intake of vegetables (odds ratio [OR], 0.35; 95% confidence interval [CI], 0.28 to 0.43) and fresh fruits (OR, 0.32; 95% CI, 0.24 to 0.43), compared to the lowest quartile.CONCLUSIONSImproving food literacy is an important factor for promoting healthy food intake in older adults as well as adults. Therefore, it is necessary to develop intervention programs to work toward this goal. -
SummaryKorean summary
건강정보 이해능력(health literacy)은 노인에서 만성질환이나 인지능력과의 관련성이 보고되고 있으나 영양정보 이해능력(food literacy)에 대한 연구는 미비하다. 급변하는 식이 환경에서 식사 및 영양과 관련된 정보를 올바르게 이해하고 판단할 수 있는 영양정보 이해능력은 노인성 질환 예방에 중요하다. 본 연구에서 영양정보 이해능력과 식품군 섭취와의 상관성을 분석한 결과 영양정보 이해능력이 높은 노인이 건강한 식품 섭취 부족 위험이 낮았다. 특히 과일 섭취 부족 위험은 영양정보 이해능력이 높은 노인에서 뚜렷하게 낮았다. 국내 영양정보 이해능력 연구는 초기 단계로 주로 성인 대상으로 연구가 이루어져서 본 연구에서의 결과는 그 의의가 크며, 영양정보 이해능력 향상은 성인과 마찬가지로 노인에서도 건강한 식품 섭취를 위한 중요한 요인으로서 이를 위한 프로그램 개발이 필요할 것으로 사료된다.Key Message
The study on food literacy among older adults in Korea is significant as previous research has mostly focused on adults. The results showed that older adults with higher food literacy score had lower risk of insufficient food intake as compared with those with lower food literacy score. Specifically, the risk of insufficient fresh fruits intake was the lowest among older adults with higher food literacy score. Therefore, improving food literacy is an important factor for promoting healthy food consumption among older adults. -
