Prior research finds that sex ratio, defined as the proportion of males and females in a given context, is related to engagement in risk-taking behaviors. However, most research operationalizes sex ratio at a local context (e.g., regional or county), which fails to reflect with precision the sex ratios contexts of individuals at a closer level. Furthermore, the relationship between sex ratio and risk-taking behaviors may be affected by individuals’ life history strategy, with previous studies showing fast life history strategies linked to risk-taking behaviors, compared to slow life history strategies. The present study analyzes the relationship between classroom sex ratio and risk-taking behaviors and the interaction between classroom sex ratio and life history strategy in adolescents. The sample comprised 1214 participants nested in 57 classrooms, 49.75% females, 91.5% Spanish and a mean age of 16.15 years (SD = 1.23, range 14–21). Results from multilevel modeling showed a negative relation between classroom sex ratio and risk-taking behaviors in female adolescents with faster life history strategy. By contrast, classroom sex ratio in male adolescents related positively to risk-taking behaviors but did not interact with life history strategy. These findings underscore the importance of studying proximate sex ratio on risk-taking behaviors in adolescents and underline its potential influence in the development and expression of life history strategies.

男性太多还是女性太多?课堂性别比例、生活史策略和冒险行为

先前的研究发现,性别比例(定义为特定背景下的男性和女性的比例)与参与冒险行为有关。然而,大多数研究在当地(例如,区域或县)背景下操作性别比例,这未能在更接近的层面上准确反映个人的性别比例背景。此外,性别比例与冒险行为之间的关系可能会受到个人生活史策略的影响,之前的研究表明,与慢速生活史策略相比,快速生活史策略与冒险行为相关。本研究分析了青少年课堂性别比例与冒险行为之间的关系以及课堂性别比例与生活史策略之间的相互作用。SD  = 1.23,范围 14-21)。多层次建模的结果显示,在具有更快生活史策略的女性青少年中,课堂性别比例与冒险行为之间存在负相关关系。相比之下,男性青少年的课堂性别比例与冒险行为呈正相关,但与生活史策略没有相互作用。这些发现强调了研究近似性别比对青少年冒险行为的重要性,并强调其对生活史策略的发展和表达的潜在影响。
