【摘要】 目的 了解居民对米酵菌酸的认知、态度、行为情况及其影响因素，为米酵菌酸食物中毒事件预防措施与健康教育策略的制定提供参考。方法 2023年4月29日-5月3日以微信公众号发布的网络问卷进行现况调查，收集居民基本情况、米酵菌酸相关知识、行为和态度3个维度的信息。调查对象按性别、年龄调整权重后采用χ2检验对米酵菌酸知信行情况进行单因素分析；采用单因素和多因素logistic回归模型对调查对象三维度得分进行多因素分析。结果 最终获得有效问卷10 754份，有效率为88%(10 754/12 231)。居民对米酵菌酸知识总体知晓率为50%，行为总体正向率为50%，态度总体积极率为43%。居民米酵菌酸食物中毒防治知信行总体合格率在不同性别、民族、学历、年龄、职业、居住地属性以及月均收入人群中的差异均有统计学意义（χ~2=56.76、316.50、131.19、360.02、75.09、282.14、78.98,P均<0.05）。女性知识、行为、态度得分均高于男性（OR=1.649、1.207、1.108,95%CI:1.506～1.805、1.108～1.315、1.017～1.207）。小学/初中及以下学历（OR=0.615,95%CI:0.499～0.753）、农村地区（OR=0.613,95%CI:0.479～0.779）知识得分更低。月收入<2 000元人群知识和行为得分均低于月收入10 000～元人群（OR=0.746、0.672,95%CI:0.615～0.903、0.565～0.799）。10～<25岁人群知识和行为得分较其他年龄组低。结论 居民米酵菌酸知识和态度整体水平低，预防米酵菌酸中毒的行为正确水平有待提高。需针对男性、年轻、低学历、月收入低及非城市居民制定相应的健康教育策略。更多还原

【Abstract】 Objective To understand the status of knowledge,attitude and practice(KAP)on bongkrekic acid and the influencing factors among the residents,and provide reference for the development of preventive measures and health education strategies for the food poisoning incident of bongkrekic acid. Methods The demographic characteristics,knowledge,attitude and practice of bongkrekic acid were investigated by questionnaire online in April 29th-May 3rd 2023.After adjusting the weights of the survey respondents according to their gender and age,the scores of knowledge,attitude and practice of bongkrekic acid were compared and the influence factors of bongkrekic acid scores were analyzed by chisquare and logistics regression. Results A total of 10 754 valid questionnaires were finally obtained,with a validity rate of88%(10 754/12 231). The total awareness rate of the participants was 50% for bongkrekic acid knowledge. The correct rates of practice and attitude were 50% and 43%,respectively. The overall qualification rate of prevention and control KAP for the food poisoning incident of bongkrekic acid was statistically significant among different gender,ethnicity,educational level,age,occupation,residential attributes and monthly average income group（χ~2=56.76,316.50,131.19,360.02,75.09,282.14,78.98;all P<0.05）. Women had higher scores in the knowledge,practice and attitude than men(OR=1.649,1.207,1.108,95%CI:1.506-1.805,1.108-1.315,1.017-1.207). Knowledge scores were low for those with elementary/middle school or lower education(OR=0.615,95%CI:0.499-0.753),and those in rural areas(OR=0.613,95%CI:0.479-0.779). The knowledge and behavior scores were lower for those with monthly income <2 000 yuan than 10 000-yuan monthly income(OR=0.746,0.672,95%CI:0.615-0.903,0.565-0.799). Knowledge and behavioral scores were lower for those aged 10-<25 years old than those for other age groups. Conclusions The residents had a generally low level of knowledge and attitude;it was necessary to improve their preventive behaviors against bongkrekic acid poisoning. Health education strategies should be designed that cater to men,young,lower educational background,lower monthly income,and non-urban residents.更多还原
