This study examined the association between socioeconomic status (SES) and obesity risk during early adolescence, ages 10-13 years, and whether this association is present in different racial/ethnic and gender groups during 2 time points in early adolescence. Data were from the Healthy Passages study, which enrolled 4,824 African American, Hispanic, and White 5th graders (ages 10-11) in a population-based, longitudinal study conducted in 3 U.S. metropolitan areas, and assessed them again 2 years later. Weight status was classified from measured body mass index using standard criteria into nonobese and obese (27% in 5th grade). SES was indexed based on highest education attainment in the household. Youth in the highest SES had a significantly lower prevalence of obesity than those of lower SES at both 5th and 7th grades when disregarding race/ethnicity. Within-racial/ethnic group analyses mostly confirmed this pattern for Hispanic and White youth, but not for African American youth. When also considering gender, the SES differential in obesity risk was more pronounced among White girls and 5th-grade Hispanic boys. Growing up in a high SES home, marked by having a member with at least a college degree, is associated with lower risk for obesity among Hispanic and White youth. For African American youth, there appears to be no association between SES and obesity. Thus the health advantage generally attributed to higher SES does not appear consistently across racial/ethnic groups for obesity in youth. Further research should identify influences on weight status beyond SES, especially among African American youth.

Introduction: As with most emerging nations, Brazil lacks up-to-date data on the prevalence of obesity and overweight among its children. Of particular concern is the lack of data on children in early adolescence, considered by many to be the crucial stage for weight-related healthcare. Objective: To assess regional, socioeconomic, and gender differences in the prevalence of obesity and overweight among Brazilian early adolescents. Methods: A cross-sectional study was conducted on a racially diverse sample of students aged 10–13 years, from schools in three geographic regions (north, northeast, south) (N = 1,738). Data on gender, age, race, socioeconomic status (SES), weight, and height were obtained. Weight class was calculated from age- and gender-adjusted body mass index, based on children’s weight and height. Bivariate and multivariable analyses, with post hoc tests, were conducted to estimate differences between groups and were corrected for multiple comparisons. Procedures were approved by institutional review boards at study sites. Results: Analyses revealed a higher prevalence of obesity and/or overweight among: (1) children of higher SES; (2) children in southern Brazil; (3) males; and (4) Black females. Conclusion: The most salient predictor of weight risk among Brazilian early adolescents is higher SES. This finding is consistent with previous findings of an inverse social gradient, in weight risk, among emerging-nation population groups.

There is considerable variability among psychology journals in Brazil, in terms of presence on the international stage. However, research as to why is very scarce. This study empirically examined the relationship between several indices of internationalization and real-world internationalization, among these journals. 661 articles from the top-17 psychology journals in Brazil were coded for: English-language text, editorial board makeup, lead author institution, and article type. Analyses revealed that successful internationalization was associated with: (i) lead author institution from a native English-speaking country; (ii) empirical articles; and (iii) editorial board members from a native English-speaking country. Use of English-language text was not associated with successful internationalization. These findings suggest that the path to internationalization for psychology journals in Brazil may depend on increased publishing of findings from English-speaking countries; or at the very least: increased collaboration between Brazilian and native English-speaking scholars.
