Effective handwashing is important for preventing exacerbation of allergic diseases, yet the relationship between allergic diseases in adolescents remains underexplored. Utilizing data from the Korea Youth Risk Behavior Survey (2009-2022), a nationwide study involving students aged 12-19, we analyzed the allergic condition, International Study of Asthma and Allergic Conditions (Never, Previous, Current), and their handwashing scores. We analyzed the trend of handwashing by allergic condition. And we conducted the ordinal logistic regression between allergic condition and handwashing, adjusted with gender, age, economic status, urbanization, smoking status, alcohol consumptions, surveyed year, and education on HW. A total of 3,258,610 adolescents were analyzed. We observed spikes in mean handwashing scores in 2009, 2013, 2015, and 2020, which corresponded with trends in allergic conditions. Adolescents with current asthma and allergic rhinitis had higher odds ratios (ORs) for better handwashing practices compared to those without these conditions. Conversely, those with current or previous atopic dermatitis had lower ORs compared to those without these conditions. In adolescent age, asthma and allergic rhinitis positively influence handwashing practices, while atopic dermatitis negatively influences handwashing practice, due to their comorbidities, highlighting the need for specialized handwashing guidelines that address the unique challenges of those with allergic diseases.

有效的洗手对于预防过敏性疾病加重非常重要，然而青少年中过敏性疾病与洗手习惯之间的关系仍需进一步研究。我们利用韩国青少年风险行为调查（2009-2022）的数据进行分析，该调查涉及12至19岁的学生群体。我们分析了国际哮喘和过敏状况研究中的过敏情况（从未有过、曾经有、目前有），以及学生的洗手评分。我们还分析了不同过敏条件下青少年的洗手习惯趋势，并进行了有序逻辑回归分析，探讨了过敏情况与洗手习惯之间的关系，调整因素包括性别、年龄、经济状况、城市化程度、吸烟状态、饮酒状况、调查年份和关于洗手的教育水平。共有3,258,610名青少年参与了本次研究。我们观察到在2009年、2013年、2015年和2020年，平均洗手评分有所上升，这些趋势与过敏情况的变化相符。患有目前哮喘和过敏性鼻炎的青少年比没有这些疾病的同龄人有更高的优秀洗手习惯的可能性比率（OR值）。相反，当前或曾经有过异位性皮炎的青少年相比那些没有这类疾病的人，有较低的优秀洗手习惯的可能性比率。在青少年年龄阶段，哮喘和过敏性鼻炎对积极养成良好的洗手习惯具有正面影响，而异位性皮炎则对其产生负面影响，这是由于这些疾病的共病情况所致，强调了需要制定专门针对过敏性疾病患者独特挑战的手洗指南。
