Abstract:
Objective:To investigate the awareness of iodine deficiency disorders prevention and control knowledge among residents in Guiyang City, as well as the behavioral and attitude characteristics of iodized salt consumption, and to determine the focus and direction of future health education on iodine deficiency disorders.Methods:From 0 : 00 to 24 : 00 on May 15, 2021 (the National Day for Prevention and Control of Iodine Deficiency Disorders), through the "Guizhou Disease Control" WeChat official account, the questionnaire was randomly distributed to the residents of Guiyang City who paid attention to the official account in the form of award-winning contest and returned. The survey content included general demographic data, iodine deficiency disorders prevention and control knowledge among residents and the behaviors and attitudes towards iodized salt consumption. The awareness rate of iodine deficiency disorders prevention and control knowledge among residents and the correct rate of their behaviors and attitudes towards iodized salt consumption were calculated.Results:A total of 3 078 valid questionnaires were collected in this survey. The awareness rate of iodine deficiency disorders prevention and control knowledge among residents was 51.3% (9 467/18 468), with a score of (51.26 ± 14.30) points; the correct rate of behavior and attitude towards iodized salt consumption was 93.0% (11 446/12 312), with a score of (92.97 ± 13.13) points. There was a statistically significant difference in the awareness rate of iodine deficiency disorders prevention and control knowledge among residents of different age groups (χ 2 = 23.03, P < 0.001). There were statistically significant differences in the correct rates of behavior and attitude towards iodized salt consumption among residents of different ages, ethnic groups, and professions (χ 2 = 9.66, 4.88, 24.73, P < 0.05), with lower correct rates in the ≥61 years old group, Han minority people and students. The main channels for obtaining knowledge on iodine deficiency disorders prevention and control were promotional materials (59.3%, 1 825/3 078), newspapers and magazines (56.8%, 1 747/3 078), television (56.6%, 1 743/3 078), and the internet (56.2%, 1 731/3 078). Conclusions:The correct rate of behavior and attitude towards iodized salt consumption among residents in Guiyang City is relatively high, but the awareness rate of iodine deficiency disorders prevention and control knowledge is low. We should strengthen health education for residents, especially the elderly, ethnic minorities, and students, and attach importance to promoting the safety of iodized salt and the necessity of long-term iodine supplementation.
