Mexican American children are disproportionately affected by obesity. Data on how the acculturation process influences diet and body weight among adolescents are limited. We used the data from the 1999-2004 NHANES, restricting to 2286 Mexican American children between 12 and 19 y old. Acculturation was measured by generation status and language preference. Diet was assessed using 24-h diet recall. Multiple linear, Tobit, logistic, and quantile regression models were used. We found, after adjusting for socio-demographic factors, health, dietary intake, physical activity, and sedentary behaviors compared to the first generation, second and third generations had greater odds of overweight and obesity. Adolescents in the second generation had higher BMI Z-scores than adolescents in the first and third generations. Both second and third generation adolescents consumed less fruit, whole fruit, vegetables, grains, and meats but more sweetened beverages, whole grains, saturated fat, sodium, oil, and energy from discretionary foods. Higher language acculturation was associated with poorer diet and greater body weight. Our findings suggest that Mexican American adolescents face challenges in terms of poorer diet and excessive weight gain associated with their immigration experience.

Background-Despite the reported effects of smokeless tobacco (ST) on the periodontium and high prevalence of ST use in rural populations and in men, studies on this specific topic are limited. The purpose of this cross-sectional investigation is to evaluate the periodontal health status of male ST users from a rural population.

This article presents a framework for developing and carrying out an implementation monitoring plan of a complex structural intervention in an organizational setting and describes seven steps for analyzing and reporting results for fidelity and completeness of implementation. This process is illustrated using the Environmental Interventions in Children's Homes (ENRICH) Wellness Project. ENRICH aimed to promote physical activity and healthful nutrition behaviors among children residing in children's group homes by working collaboratively with organizational staff. A comprehensive implementation monitoring plan was developed based on the particulars of the setting, context, and the program framework and used multiple data sources, criteria for evidence of implementation, and data triangulation to examine evidence for organizational implementation. Eleven of 17 organizations (65%) met the criteria for nutrition implementation whereas 9 of 17 (53%) met the criteria for physical activity implementation. Implementation data can be used descriptively, as described here, and may also be used in future outcome analyses to better understand project outcomes. The framework and evaluation approach are applicable to complex interventions in other organizational settings.
