This study evaluates onychophagia or nail biting (NB) prevalence and association with mental health of a community sample of children from Shiraz, Iran.
The parents of 743 primary school children, selected by random sampling, reported NB behavior of their children and themselves. Children's mental health problem was assessed using the Strengths and Difficulties Questionnaire (SDQ). 22.3% (95% CI: 19.3 to 25.3) of children had NB behavior in the last three months (girls: 20.1% (95% CI: 15.9 to 24.2). The rate in boys was 24.4% (95% CI: 20.1 to 28.7). 36.8% of the children with NB had at least one family member with nail biting. Older age was associated with a higher prevalence of NB while a higher score on the prosocial score was associated with a lower prevalence of NB.
NB is a very common behavior in both genders in children and their family members. Children with NB have less prosocial ability than those without it.
本研究评估了伊朗设拉子社区样本中儿童咬甲癖或咬指甲(NB)的患病率及其与心理健康的关联。
通过随机抽样选取的743名小学生的家长报告了他们孩子及自己的咬指甲行为。使用长处和困难问卷(SDQ)评估儿童的心理健康问题。在过去三个月中,22.3%(95%置信区间:19.3%至25.3%)的儿童有咬指甲行为(女孩:20.1%(95%置信区间:15.9%至24.2%),男孩的比例为24.4%(95%置信区间:20.1%至28.7%)。咬指甲的儿童中,36.8%至少有一名家庭成员有咬指甲行为。年龄较大与咬指甲患病率较高相关,而亲社会得分较高与咬指甲患病率较低相关。
咬指甲在儿童及其家庭成员中是一种非常常见的行为。有咬指甲行为的儿童比没有这种行为的儿童亲社会能力更弱。
