BACKGROUND: Tobacco use and tobacco-related diseases disproportionately affect Alaska Native (AN) people. Using telemedicine, this study aims to identify culturally-tailored, theoretically-driven, efficacious interventions for tobacco use and other cardiovascular disease (CVD) risk behaviors among AN people in remote areas.DESIGN: Randomized clinical trial with two intervention arms: 1) tobacco and physical activity; 2) medication adherence and a heart-healthy AN diet.PARTICIPANTS: Participants are N = 300 AN men and women current smokers with high blood pressure or high cholesterol.INTERVENTIONS: All participants receive motivational, stage-tailored, telemedicine-delivered counseling sessions at baseline and 3, 6, and 12 months follow-up; an individualized behavior change plan that is updated at each contact; and a behavior change manual. In Group 1, the focus is on tobacco and physical activity; a pedometer is provided and nicotine replacement therapy is offered. In Group 2, the focus is on medication adherence for treating hypertension and/or hypercholesterolemia; a medication bag and traditional food guide are provided.MEASUREMENTS: With assessments at baseline, 3, 6, 12, and 18 months, the primary outcome is smoking status, assessed as 7-day point prevalence abstinence, biochemically verified with urine anabasine. Secondary outcomes include physical activity, blood pressure and cholesterol, medication compliance, diet, multiple risk behavior change indices, and cost-effectiveness.COMMENTS: The current study has the potential to identify novel, feasible, acceptable, and efficacious interventions for treating the co-occurrence of CVD risk factors in AN people. Findings may inform personalized treatment and the development of effective and cost-effective intervention strategies for use in remote indigenous communities more broadly. Clinical Trial Registration # NCT02137902.

This aim of this study was to examine whether the construct of physical appearance perception differed among the three largest racial/ethnic groups in the United States using an adolescent sample.Black (46%), Latino (31%), and White (23%) adolescents in Grade 10 from the Healthy Passages study ( N = 4,005) completed the Harter's Self-Perception Profile for Adolescents-Physical Appearance Scale (SPPA-PA) as a measure of physical appearance perception.Overall, Black adolescents had a more positive self-perception of their physical appearance than Latino and White adolescents. However, further analysis using measurement invariance testing revealed that the construct of physical appearance perception, as measured by SPPA-PA, was not comparable across the three racial/ethnic groups in both males and females.These results suggest that observed differences may not reflect true differences in perceptions of physical appearance. Measures that are equivalent across racial/ethnic groups should be developed to ensure more precise measurement and understanding.

Little is known about influences on weight loss attempts, yet about one-half report making such attempts during adolescence. The aim was to examine the relationships among weight loss attempts, body size, and body perception in racially/ethnically diverse young adolescents.3,954 African American, Latino, and White 5th-graders completed the Self-Perception Profile-Physical Appearance Scale and questions regarding body perceptions and past and current weight loss attempts, and had their weight and height measured.Latino youth most often and White youth least often reported weight loss attempts. Larger body size and negative body perception were related to more reported weight loss attempts in White and Latino youth. Body perception mediated the relationship between body size and weight loss attempts for White youth.Motivations to lose weight appear to differ among racial/ethnic groups, suggesting that interventions for healthy weight control in youth may need to target racial/ethnic groups differently.
