Latino youth in the US are disproportionately burdened by overweight, obesity and diabetes placing them at greater risk for developing diabetes and other cardiovascular diseases in adulthood. Acculturation, parenting strategies and parental health behaviors, and psychological health have each emerged as correlates of cardio-metabolic disease (e.g., overweight, dyslipidemia, hypertension, dysglycemia) in samples of Latino youth. The objective of the proposed study is to build upon earlier research to test a comprehensive and culturally relevant model of obesity risk informed by Social Cognitive Theory in a diverse sample of Latino children and adolescents (ages 8-14) from across the US. Specific Aims are as follows: (1) Evaluate the influence of youth acculturation and intergenerational differences in acculturation between youth and parents on youth’s lifestyle behaviors and their cardiometabolic risk profiles; (2) Test the association of parenting strategies and parental health beahviors with youth’s lifestyle behaviors and cardiometabolic risk profiles; and, (3) Assess the influence of youths’ psychosocial functioning on youth lifestyle behaviors and cardiometabolic risk profiles. The proposed ancillary study to the Hispanic Community Health Study/ Study of Latino Health (HCHS/SOL), SOL-Youth will recruit a sample of 1,600 boys and girls ages 8 to 14 from each of the 4 field centers (Bronx, NY; Chicago, IL; Miami, FL; San Diego, CA) who have least one parent participating in HCHS/SOL. HCHS/SOL is a NIH-funded multi-center epidemiologic study designed to examine risk factors for cardiovascular diseases and diabetes in 16,000 Latino adults (ages 18-74) of Mexican, Cuban, Puerto Rican and South/Central American descent. SOL-Youth participants will undergo a single 3-hour clinical examination and will wear a portable physical activity monitor for 7 days after the exam. During the clinical examination, youth will complete an interviewer-administered questionnaire with questions on acculturation, pubertal development, psychological functioning, physical activity, diet, and family meal patterns. Clinic staff will collect anthropometric, blood pressure, and blood lipid data from participating youth and participants will complete an aerobic fitness test. Data on the parents of participating youth will be obtained primarily from existing data collected through the HCHS/SOL study in addition to a 1-hour survey about their child’s medical histories, behaviors and their parenting strategies. With detailed parent and child information on risk and protective factors, SOL-Youth will characterize the complex relationships between psychosocial factors and obesity in Latino youth using sophisticated multivariable analyses and structural equation modeling. Findings will have practice and policy implications to prevent youth risk factors from leading to adult health consequences.
