城市化与青少年健康之间的关系是一个关键问题，但几乎没有经验证据报道。尽管有人提出了一种联系，但将农村与城市进行二分比较可能无法成功地确定青少年环境之间的差异。本研究的目的是评估当地规模的风险行为在全国样本的年轻墨西哥人生活在低收入家庭的影响，同时考虑社会经济地位（SES）的调节作用。这是对墨西哥在农村、半城市和城市地区等不同环境下对低收入家庭进行的三次全国调查的二次分析。我们分析了15-21岁青少年的风险行为及其与城市化的潜在关系。探讨的危险行为有：吸烟和饮酒，性开始和使用安全套。青少年的居住地根据每个地区的居民人数进行分类。我们使用了一个逻辑模型，以确定当地规模和风险行为之间的关联，包括与SES的相互作用项。最终样本包括来自墨西哥704个地区的17，974名青少年。地方规模与烟草和酒精消费相关，在所有SES水平中显示出类似的效果：与农村环境相比，地方规模越大，消费烟草或酒精的风险越低。地点大小对性行为的影响更为复杂。只有在社会经济地位最低的青少年中，在较大的地区，青少年使用安全套的几率较高。我们发现，没有统计学显着的地方大小和性启动之间的关联。结果表明，在这个样本的青少年从墨西哥低收入地区，危险行为与地方规模（居民人数）。此外，对于安全套的使用，这种关系是由社会经济地位的调节。这种异质性表明，需要更详细地分析城市化对行为的影响，以及应对这种情况所需的反应-这也是异质性的。
The relationship between urbanicity and adolescent health is a critical issue for which little empirical evidence has been reported. Although an association has been suggested, a dichotomous rural versus urban comparison may not succeed in identifying differences between adolescent contexts. This study aims to assess the influence of locality size on risk behaviors in a national sample of young Mexicans living in low-income households, while considering the moderating effect of socioeconomic status (SES). This is a secondary analysis of three national surveys of low-income households in Mexico in different settings: rural, semi-urban and urban areas. We analyzed risk behaviors in 15-21-year-olds and their potential relation to urbanicity. The risk behaviors explored were: tobacco and alcohol consumption, sexual initiation and condom use. The adolescents' localities of residence were classified according to the number of inhabitants in each locality. We used a logistical model to identify an association between locality size and risk behaviors, including an interaction term with SES. The final sample included 17,974 adolescents from 704 localities in Mexico. Locality size was associated with tobacco and alcohol consumption, showing a similar effect throughout all SES levels: the larger the size of the locality, the lower the risk of consuming tobacco or alcohol compared with rural settings. The effect of locality size on sexual behavior was more complex. The odds of adolescent condom use were higher in larger localities only among adolescents in the lowest SES levels. We found no statically significant association between locality size and sexual initiation. The results suggest that in this sample of adolescents from low-income areas in Mexico, risk behaviors are related to locality size (number of inhabitants). Furthermore, for condom use, this relation is moderated by SES. Such heterogeneity suggests the need for more detailed analyses of both the effects of urbanicity on behavior, and the responses--which are also heterogeneous--required to address this situation.
