RESUMO
BACKGROUND: Puerto Rican adults residing in the US mainland experience a high prevalence of metabolic syndrome (MetS). A diet containing healthy protein-rich sources may help control risk factors for MetS. OBJECTIVE: This study aimed to evaluate 2-year longitudinal associations between intake of various protein-rich foods and changes in the six MetS components. DESIGN: This is a secondary analysis of a longitudinal cohort study using data from the baseline (2004-2007) and 2-year follow-up visits (2006-2011) in the Boston Puerto Rican Health Study. PARTICIPANTS/SETTING: Participants were self-identified Puerto Ricans, aged 45 to 75 years, residing in Boston, Massachusetts, or the surrounding area (n = 1,126). MAIN OUTCOME MEASURES: MetS components were fasting glucose, high-density lipoprotein (HDL) cholesterol, triglycerides, systolic and diastolic blood pressures, and waist circumference. STATISTICAL ANALYSIS: Baseline intake of foods reported in a semiquantitative food frequency questionnaire were expressed as servings/day, and protein-rich foods were categorized as unprocessed white meat, unprocessed red meat, processed meat, milk and yogurt, cheese, fish and seafood, beans, nuts, and eggs. Associations between each continuous protein food group and continuous 2-year change in MetS components were assessed using linear mixed models adjusted for socioeconomic and behavioral factors, and other dietary sources. RESULTS: The top contributors to total protein intake were unprocessed red meat (13.3%) and unprocessed poultry (13.0%), and the lowest were eggs (2.92%) and nuts (0.91%). Higher intake of processed meats was associated with an increase in waist circumference over 2 years (ß = 1.28; standard error [SE] = 0.63), whereas higher intake of fish and seafood was associated with a decrease in waist circumference (ß = -3.47; SE = 1.39). Intake of unprocessed poultry was associated with a decrease in triglycerides (ß = -24.5; SE = 9.13). No other significant associations were observed between protein sources and 2-year changes in MetS components. CONCLUSIONS: Consuming less processed meat and more fish and seafood and unprocessed poultry was associated with decreases in waist circumference and triglycerides among US mainland Puerto Ricans. Other dietary protein sources were not related to cardiometabolic health.

BACKGROUND: Adults in Puerto Rico experience an excessive burden of central obesity. It remains unknown which dietary components are more strongly associated with central obesity in this high-risk group. We aimed to evaluate the relationship of the Mediterranean diet (MeDS) and Alternate Healthy Eating Index 2010 (AHEI) with central obesity in the Puerto Rico Assessment of Diet, Lifestyle and Diseases (PRADLAD) cross-sectional study. METHODS: Data from PRADLAD participants (ages 30-75 years) were used (n = 166). Dietary intake was assessed by food frequency questionnaire. The MeDS [nine components; range: 0 (lowest) to 9 (highest observance of a Mediterranean-like diet)] and AHEI [11 components; range: 0 (lowest) to 110 (highest diet quality)] were defined. Daily intake of foods and beverages within each MeDS component was ranked by contribution to total energy intake. Multivariable logistic regression was used to evaluate associations between MeDS and AHEI with central obesity (waist circumference > 102 cm males,â¯> 88 cm females). RESULTS: Mean ± SD MeDS was 4.46 ± 1.77 and AHEI was 60.2 ± 11.1. Traditional foods representative of the MeDS included potatoes, root vegetables, fruit juice, avocados, bread, oatmeal, beans, chicken, seafood, low-fat milk, cheese, eggs and beer. Adjusted odds ratios and 95% confidence intervals of central obesity were 0.78 (0.63-0.97) per unit increment of MeDS and 0.61 (0.42-0.90) per 10-unit increment of AHEI. CONCLUSIONS: Higher adherence to MeDS or AHEI was associated with lower central obesity in adults in Puerto Rico. Consuming traditional foods reflecting these dietary patterns (i.e., Mediterranean-like) may reduce central obesity in high-risk populations.

Dysfunctional eating behaviors (DEB: emotional eating (EE), uncontrolled eating (UE) and cognitive restraint (CR)) are prevalent in U.S. Latinos and may influence diet. However, this has not been studied in Puerto Rico (PR). This study documents DEB in PR, and explores associations with diet. Cross-sectional study of adults (n = 92) in Ponce, PR. DEB were measured with the TFEQ-R18-V2. The Block Fat and Fruits and Vegetables Screener measured dietary intake. Analysis included adjusted proportions, means and linear regressions. 76%, 88%, and 87% of participants experienced EE, UE and CR, respectively. EE was associated with calories from fats (ß = 1.95, 95% CI 0.40, 3.51) and saturated fats (ß = 3.26, 95% CI 0.67, 5.85), and CR with fruits and vegetables (ß = 0.69, 95% CI 0.20, 1.19). A large percentage of the sample experienced DEB. EE and CR were associated with dietary intake. Studies are needed to understand associations between DEB, diet and health in PR.
