Delinquency refers to a juveniles’ behavior pattern characterized by repeated offending, and is regarded mainly in its social, but also criminal aspects. Delinquent and non-delinquent individuals may be a product of the same society or even the same family. Young individuals who are unable to find affection and protection within the family may become more susceptible to delinquency as a form of empowerment. More than socioeconomic conditions, the lack of interaction between parents and children, the existence of psychopathological problems in either parent, and academic problems, together with a biological vulnerability, may be deciding factors for the involvement of young individuals in delinquent behavior. This review aims to analyze the influence of environmental and genetic factors in the development of delinquent behavior. Studies related to the influence of the environment and genes on the development of delinquent behavior were obtained from multiple databases, through rigorous exclusion and inclusion criteria. Of the 152 documents retrieved, 87 were retained for further analysis, and 36 final studies were considered eligible for inclusion. In addition to these, ten studies were added trough manual search, with the final sample thus comprising 46 articles, published between 1983 and 2016. Objectives, methodological aspects (samples and instruments), and main conclusions were extracted from each study. Overall, the interaction between genetic and environmental factors appears to best explain the variation of delinquent behavior. Environmental risk factors may have differential effects on the behavior of individuals, particularly according to their genetic propensity for delinquency.

犯罪行为：对遗传和环境风险因素的系统评价。

犯罪行为是指青少年的行为模式，其特征是屡犯不法，主要是在社会方面，在犯罪方面也是如此。犯罪者和非犯罪者可能是同一社会甚至同一家庭的产物。无法在家庭中找到感情和保护的年轻人可能会更容易受到犯罪的影响，这是一种赋权的形式。除了社会经济状况之外，父母与孩子之间缺乏互动，父母双方都存在心理病理问题以及学术问题以及生物学上的脆弱性，可能是年轻人参与犯罪行为的决定因素。本文旨在分析环境和遗传因素对犯罪行为发展的影响。通过严格的排除和纳入标准，从多个数据库中获得了有关环境和基因对犯罪行为发展的影响的研究。在检索到的152篇文档中，保留了87篇以作进一步分析，并且认为有36篇最终研究符合纳入条件。除此之外，通过手动搜索添加了十项研究，最终样本包括1983年至2016年之间发表的46篇文章。目的，方法论方面（样本和仪器）以及主要结论均从每项研究中提取。总体而言，遗传因素与环境因素之间的相互作用似乎可以最好地解释犯罪行为的变化。环境风险因素可能会对个人行为产生不同的影响，
