Participants in experimental group received health education and six sessions of health literacy. Each session lasted 20-60 minutes within eight weeks. Control group received usual care and health education from health provider. self-administration questionnaire (nutrition literacy, food consumption pattern and self-management) was used to collect the data. Data were analyzed using independent t-test. Group reflection was analyzed using content analysis. Results showed that mean score of nutritional literacy, food consumption and self-management of the experiment group was significantly higher than the mean score of the control group (p-value <.001). Results from the reflection in the experimental group suggested some issues, including the understanding, access to information and applying knowledge.
