    <p>Abstract</p> <p>Background</p> <p>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).</p> <p>Methods</p> <p>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.</p> <p>Results</p> <p>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.</p> <p>Conclusions</p> <p>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.</p

    The free-market city: Latin American urbanization in the years of the neoliberal experiment

    We examine the evolution of Latin American cities in the last two decades of the twentieth century and in the first years of the twenty-first on the basis of comparable data from six countries comprising over 80 percent of the region’s population. These years correspond to the shift in hegemonic models of development in the region, from import-substitution industrialization to neoliberal “open markets” adjustment. We examine how the application of the new policies correlates with change patterns in four areas: urban systems and urban primacy; urban unemployment and informal employment; poverty and inequality; and crime, victimization, and urban insecurity. We present detailed analyses of each of these topics based on the latest available data for the six countries. We conclude that significant changes in patterns of urbanization have taken place in the region, reflecting, in part, the expected and unexpected consequences of the application of the new model of development. Implications of our findings for each of the four areas examined and for the future of the region are discussed
