인터넷 건강정보이해능력과 정보탐색 유형별 인지된 정보유용성 분석: 다이어트 및 체중조절 관련 정보탐색을 중심으로

초록

Background: This study aimed to examine (1) the patterns of online health information search with respect to seeking and scanning, and (2) how online search, along with eHealth literacy, predicts perceived information usefulness in the context of diet and weight control. Methods: Online survey was conducted with 299 adults from the consumer panel recruited for the purpose of quality assessment of the Korean National Health Information Portal in 2016. We conducted paired sample t-test and multiple logistic regression to address the research questions. Data analysis was performed using IBM SPSS Statistics ver. 24.0 (IBM Corp., Armonk, NY, USA) and SAS ver. 9.3 (SAS Institute Inc., Cary, NC, USA). Results: Of the respondents, 38.8% were ‘high seek-high scanners,’ 35.8% were ‘low seek-low scanners,’ 13.0% were ‘high seek-low scanners,’ and 12.4% were ‘low seek-high scanners.’ eHealth literacy was a significant, positive predictor of online information scanning (odds ratio [OR], 2.46; 95% confidence interval [CI], 1.41–4.29), but not for online information seeking (OR, 1.75; 95% CI, 1.00– 3.05). With respect to perceived usefulness of online information seeking, online seeking (OR, 4.90; 95% CI, 2.19–11.00) and eHealth literacy (OR, 2.30; 95% CI, 1.11–4.75) were significant predictors. Perceived usefulness of online scanning had a significant association with online scanning (OR, 2.38; 95% CI, 1.08–5.22), but not with eHealth literacy. Conclusion: To increase the effectiveness of the health policy for online information search and related outcomes in the context of diet and weight control, it is important to develop education programs promoting eHealth literacy.
