The purpose of this study was to estimate the frequency and to assess the determinants of physical fighting among Portuguese school-going adolescents.
A cross-sectional evaluation of urban adolescents born in 1990 and enrolled in public and private schools of Porto was performed in 2007. We identified 3161 17-year-old eligible adolescents and 73.3% accepted to participate. Information was collected using a self-administered questionnaire assessing socio-demographic, behavioural, family and health-related characteristics. The magnitude of the associations between those characteristics and physical fighting was estimated using logistic regression.
Overall, 33.8% of adolescents (48.6% of boys and 20.1% of girls; p < 0.001) engaged in a physical fight during the previous 12 months. The school premises were the most frequently reported setting where fights occurred (girls--41.2% and boys--46.7%, p = 0.179). After adjustment, and in both genders, we found statistically significant associations between physical fighting and grade retention, smoking, drinking and age at first sexual intercourse.
Physical fighting among school-going adolescents is frequent, tends to occur at school premises and to cluster with other well recognized adverse health behaviours.
本研究旨在评估葡萄牙在校青少年发生身体打架的频率，并分析其决定因素。
2007 年对波尔图市公立和私立学校中 1990 年出生的城市青少年进行了一项横断面评估。我们共确定了 3161 名 17 岁的合格青少年，其中 73.3%的人同意参与。使用自我管理式问卷收集了有关社会人口统计学、行为、家庭和健康相关特征的信息。使用逻辑回归评估了这些特征与身体打架之间的关联程度。
总体而言，33.8%的青少年（男孩 48.6%，女孩 20.1%；p < 0.001）在过去 12 个月内发生过身体打架。打架最常发生的地点是学校场地（女孩为 41.2%，男孩为 46.7%；p = 0.179）。调整后，在两性中，我们发现身体打架与留级、吸烟、饮酒和初次性行为年龄之间存在统计学显著关联。
在校青少年中，身体打架现象普遍存在，往往发生在学校场地，且与其他公认的不良健康行为相关。
