Objectives: Diet-disease associations may vary by population. We aimed to compare diet quality and its association with excess body weight (EBW: overweight and obesity), central adiposity (CA), and cardiovascular disease risk factors (CVDR) among Brazilian adolescents from São Paulo, Brazil and Hispanic/Latino adolescents from USA.
Methods: Cross-sectional data from adolescents aged 12-16y was analyzed from The Health Survey of São Paulo (HSP; n=189), and The Hispanic Community Health Study/Study of Latino Youth (SOL-Youth; n=787). Socioeconomic, anthropometric, clinical, and lifestyle data were collected in person and by phone. EBW was defined using World Obesity Federation cutoffs; CA was defined as waist circumference > 90th sex- and age-specific percentile; and CVDR was categorized as ≥ 3 of: obesity, high systolic or diastolic blood pressure, dyslipidemia, high fasting plasma glucose or hemoglobin A1c, or insulin resistance. Food intake was assessed by two 24-hour dietary recalls and NCI method was used to estimate usual intake. Diet quality was defined using the Alternate Healthy Eating Index-2010 (AHEI) and the Revised Brazilian Healthy Eating Index (BHEI-R). Adjusted odds ratios (95% CI) for EBW, CA, and CVDR by diet quality index were tested using logistic regression models. Results: Prevalence (95% CI) of EBW, CA, and CVDR was 28.7% (21.7, 35.7), 6.5% (2.9, 10.1), and 18.8% (12.9, 24.7) in HSP and 42.5% (37.5, 47.5), 12.6% (9.5, 15.6), and 17.2% (14.2, 20.3) in SOL-Youth. HSP participants with EBW (vs. without) had marginally lower (unhealthier) scores for whole grains and sugary beverages using BHEI-R. SOL-Youth participants with EBW had lower scores of nuts and legumes using AHEI, and sodium using BHEI-R, but higher scores of whole grains and dairy using BHEI-R. In HSP, BHEI-R was inversely associated with EBW (0.87; 0.80, 0.95) and CVDR (0.89; 0.80, 0.98) and AHEI was marginally associated with CA (0.90; 0.79, 1.02). In SOL-Youth, AHEI was inversely associated with EBW (0.93; 0.87, 0.99). No other associations were significant.
Conclusions: Healthier diet quality was associated with lower odds of EBW in Brazilian and USA-Hispanic/Latino adolescents and with lower CVDR in Brazilian adolescents, especially when measuring diet quality with indexes applicable to each population.
