Mexican mothers have an important role in adolescent sexuality; however, they report multiple barriers to parent–child sex communication, which may impact adolescent sexual behaviour. This cross-sectional study examines whether adolescent perceptions of maternal barriers to communication are associated with adolescent sexual behaviour frequency indirectly through its association with maternal monitoring, and whether these associations differ by age and gender. Mexican adolescents (N = 1433), ages 12–19 (53% girls), completed a survey on normative sexual behaviours, adolescent perceptions of maternal barriers to sex communication, and maternal monitoring. Structural equation modelling analyses revealed that more barriers to communication (adolescent perceptions) were associated with more sexual behaviour frequency (i.e., oral and vaginal sex) among Mexican adolescents indirectly through its association with maternal monitoring. Findings were stronger for adolescents in 8th grades, but no differences were found by gender. This model expands our understanding of the parenting factors that impact Mexican adolescent sexuality.

墨西哥青少年中母亲与青少年就性、母亲监测和性行为进行交流的障碍

墨西哥母亲在青少年性行为中扮演着重要角色；然而，他们报告了亲子性交流的多重障碍，这可能会影响青少年的性行为。这项横断面研究通过与母亲监测的关联，检查青少年对母亲沟通障碍的看法是否与青少年性行为频率间接相关，以及这些关联是否因年龄和性别而异。墨西哥青少年 ( N = 1433)，年龄在 12-19 岁之间（53% 是女孩），完成了一项关于规范性行为、青少年对母亲性交流障碍的看法以及母亲监测的调查。结构方程模型分析表明，墨西哥青少年更多的沟通障碍（青少年的看法）与更多的性行为频率（即口交和阴道性交）间接相关，这与母亲监测有关。8 年级青少年的调查结果更强，但没有发现性别差异。该模型扩展了我们对影响墨西哥青少年性行为的养育因素的理解。
