title: Knowledge and practice related to trachoma among children in Vietnam: a cross-sectional study.
abstract: A cross-sectional descriptive survey to determine the magnitude and determinants of knowledge and practice in relation to trachoma among children in Vietnam is presented. Interviews were conducted with 358 children ages 6 to 15 years in three districts of Northern Vietnam using a closed-ended questionnaire. Responses related to causes, prevention methods, consequences, and observed preventive practices were standardized. The knowledge of causes of trachoma and prevention methods was assessed as "excellent" in 61.1% and 69.45% of female and male children, respectively. Mode of transmission and consequences of trachoma were very well known to 68.70% and 57.74% of female and male children, respectively. Trachoma control practice was excellent in 54.72% of children. Females had better knowledge, and practice of trachoma control was better in female than male children. Ten- to 15-year-olds had better knowledge and practices than 6- to 10-year-old children. Trachoma knowledge and practice was better in children of Vinh Loc District of Thanh Hoa Province than in those in Tu Ky District of Hai Duong Province. The schools were the best source of the information. Mass media had a limited role. The outcome suggested a limited positive impact of the 6 months intense initiatives of a health education campaign. Based on the study results, the campaign could be reorganized to focus on high-risk groups and to improve the impact. The findings could be compared to the results of a similar study after 2 years of the campaign.
