Background: Both the incidence of diabetes mellitus and consumption of sugar-sweetened beverages are high in the Hispanic/Latino population in the United States. The associations between consumption of sugar-sweetened beverages, artificially sweetened beverages, and 100% fruit juice with prediabetes and glucose metabolism markers in the diverse Hispanic/Latino population in the United States are unknown.Objectives: The objective of this study was to examine the cross-sectional associations between consumption of sugar-sweetened beverages, artificially sweetened beverages, and 100% fruit juice with prediabetes and glucose metabolism markers such as fasting glucose and insulin, 2-h oral-glucose-tolerance test, HOMA-IR, HOMA index for β-cell function (HOMA-B), and glycated hemoglobin (HbA1c) among US Hispanic/Latino adults.Methods: Using baseline data from the Hispanic Community Health Study/Study of Latinos (2008-2011), beverage consumption was ascertained using two 24-h dietary recalls and a food propensity questionnaire. Diabetes/prediabetes status was defined by self-report, antihyperglycemic medication use, and American Diabetes Association laboratory criteria. Among 9965 individuals without diabetes (5194 normoglycemia, 4771 prediabetes) aged 18-74 y, the associations of beverage consumption with prediabetes and glucose metabolism markers were analyzed using logistic and linear regressions, respectively, accounting for complex survey design.Results: Compared with individuals who consumed <1 serving/d (<240 mL/d) of sugar-sweetened beverages, individuals who consumed >2 servings/d (>480 mL/d) had 1.3 times greater odds of having prediabetes (95% CI: 1.06, 1.61) and higher glucose metabolism markers including fasting glucose, fasting insulin, HOMA-IR, and HbA1c. Consumption of artificially sweetened beverages showed an inverse association with β-cell function (HOMA-B). Intake of 100% fruit juice was not significantly associated with prediabetes nor with glucose metabolism markers.Conclusions: Among US Hispanic/Latino adults, higher sugar-sweetened beverage consumption was associated with increased odds of prediabetes and higher glucose metabolism markers. Public health initiatives to decrease sugar-sweetened beverage consumption could potentially reduce the burden of diabetes among Hispanics/Latinos in the United States.

Background Trimethylamine- N -oxide (TMAO), a diet-derived and gut microbiota–related metabolite, is associated with cardiovascular disease (CVD). However, major dietary determinants and specific gut bacterial taxa related to TMAO remain to be identified in humans. Objectives We aimed to identify dietary and gut microbial factors associated with circulating TMAO. Methods This cross-sectional study included 3972 participants (57.3% women) aged 18–74 y from the Hispanic Community Health Study/Study of Latinos in the United States. Dietary information was collected by 24-h dietary recalls at baseline interview (2008–2011), and baseline serum TMAO and its precursors were measured by an untargeted approach. Gut microbiome was profiled by shotgun metagenomic sequencing in a subset of participants (n = 626) during a follow-up visit (2016–2018). Logistic and linear regression were used to examine associations of inverse-normalized metabolites with prevalent CVD, dietary intake, and bacterial species, respectively, after adjustment for sociodemographic, behavioral, and clinical factors. Results TMAO was positively associated with prevalent CVD (case number = 279; OR = 1.34; 95% CI: 1.17, 1.54, per 1-SD). Fish (P = 1.26 × 10
−17 ), red meat (P = 3.33 × 10−16 ), and egg (P = 3.89 × 10−5 ) intakes were top dietary factors positively associated with TMAO. We identified 9 gut bacterial species significantly associated with TMAO (false discovery rate <0.05). All 4 species positively associated with TMAO belong to the order Clostridiales , of which 3 might have homologous genes encoding carnitine monooxygenase, an enzyme converting carnitine to trimethylamine (TMA). The red meat–TMAO association was more pronounced in participants with higher abundances of these 4 species compared with those with lower abundance (Pinteraction = 0.013), but such microbial modification was not observed for fish–TMAO or egg–TMAO associations. Conclusion In US Hispanics/Latinos, fish, red meat, and egg intakes are major dietary factors associated with serum TMAO. The identified potential TMA-producing gut microbiota and microbial modification on the red meat–TMAO association support microbial TMA production from dietary carnitine, whereas the fish–TMAO association is independent of gut microbiota.

Background The association between accelerometer-assessed physical activity and risk of diabetes remains unclear, especially among US Hispanic/Latino adults who have lower levels of physical activity and a higher diabetes burden compared with other racial/ethnical populations in the country. Objectives To examine the association between accelerometer-assessed physical activity and incident diabetes in a US Hispanic/Latino population. Methods We included 7280 participants of the Hispanic Community Health Study/Study of Latinos who aged 18–74 y and free of diabetes at baseline. Data on moderate-to-vigorous physical activity (MVPA) were collected using a 7-d accelerometer measurement. Incident diabetes was assessed after a mean ± SD of 6.0 ± 0.8 y using standard procedures including blood tests. RRs and 95% CIs of diabetes associated with MVPA were estimated using survey Poisson regressions. The associations of MVPA with 6-y changes in adiposity measures were also examined. Results A total of 871 incident cases of diabetes were identified. MVPA was inversely and nonlinearly associated with risk of diabetes (P -nonlinearity = 0.006), with benefits accruing rapidly at the lower end of MVPA range (<30 min/d) and leveling off thereafter. The association differed by population age (P -interaction = 0.006). Higher MVPA was associated with lower risk of diabetes among individuals older than 50 y (RR
Q4 versus Q1 = 0.50; 95% CI: 0.35, 0.73; P -trend < 0.001) but not among younger individuals (RRQ4 versus Q1 = 0.98; 95% CI: 0.66, 1.47; P -trend = 0.92). An inverse association between MVPA and 6-y gain in waist circumference was also limited to the older group (P -interaction with age < 0.001). Conclusions Among US Hispanic/Latino adults, baseline accelerometer-derived MVPA was inversely associated with incident diabetes only among individuals aged 50 y and older. Further studies are needed to confirm our findings and to clarify potential mechanisms underlying the possible age differences in the MVPA–diabetes association. This study was registered at clinicaltrials.gov as NCT02060344. [ABSTRACT FROM AUTHOR]- Published

Background Genetic or pharmacological inhibition of de novo sphingolipid synthases prevented diabetes in animal studies. Objectives We sought to evaluate prospective associations of serum sphingolipids with incident diabetes in a population-based cohort. Methods We included 2010 participants of the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) aged 18–74 y who were free of diabetes and other major chronic diseases at baseline (2008–2011). Metabolomic profiling of fasting serum was performed using a global, untargeted approach. A total of 43 sphingolipids were quantified and, considering subclasses and chemical structures of individual species, 6 sphingolipid scores were constructed. Diabetes status was assessed using standard procedures including blood tests. Multivariable survey Poisson regressions were applied to estimate RR and 95% CI of incident diabetes associated with individual sphingolipids or sphingolipid scores. Results There were 224 incident cases of diabetes identified during, on average, 6 y of follow-up. After adjustment for socioeconomic and lifestyle factors, a ceramide score (RR
Q4 versus Q1 = 2.40; 95% CI: 1.24, 4.65; P -trend = 0.003) and a score of sphingomyelins with fully saturated sphingoid-fatty acid pairs (RRQ4 versus Q1 = 3.15; 95% CI: 1.75, 5.67; P -trend <0.001) both were positively associated with risk of diabetes, whereas scores of glycosylceramides, lactosylceramides, or other unsaturated sphingomyelins (even if having an SFA base) were not associated with risk of diabetes. After additional adjustment for numerous traditional risk factors (especially triglycerides), both associations were attenuated and only the saturated-sphingomyelin score remained associated with risk of diabetes (RRQ4 versus Q1 = 1.98; 95% CI: 1.09, 3.59; P -trend = 0.031). Conclusions Our findings suggest that a cluster of saturated sphingomyelins may be associated with elevated risk of diabetes beyond traditional risk factors, which needs to be verified in other population studies. This study was registered at clinicaltrials.gov as NCT02060344. [ABSTRACT FROM AUTHOR]- Published

Background: Away-from-home foods (AFHFs) influence diet quality, a modifiable obesity risk factor, with limited generalizable evidence in Hispanic/Latino adults.Objective: We investigated associations between AFHF intake with diet quality and overweight or obesity among US Hispanic/Latino adults.Methods: Cross-sectional baseline (2008-2011) analyses included adults (n = 16,045) aged 18-74 y in the national Hispanic Community Health Study/Study of Latinos. Participants self-reported AFHF consumption frequency from 10 different settings and dietary intake (2-d 24-h recall). The Alternate Healthy Eating Index-2010 (AHEI-2010) was used to measure diet quality; higher scores indicated a healthier diet and scores were categorized into tertiles. WHO classifications categorized overweight [body mass index (BMI; kg/m2): 25.0-29.9] and obesity (BMI ≥30). Multivariate-adjusted associations of AFHF frequency or type with AHEI-2010, overweight, or obesity were assessed by using complex survey logistic regression (ORs and 95% CIs).Results: Almost half of participants (47.1%) reported eating AFHFs ≥5 times/wk. The mean ± SE AHEI-2010 score was 47.5 ± 0.2. More than one-third (37.2%) were classified as overweight and 39.6% classified as obese. Compared with consuming AFHFs ≥5 times/wk, consuming AFHFs <1 time/wk or 1-2 times/wk was associated with greater odds of being in higher AHEI-2010 tertiles, indicating a healthier diet [<1 time/wk-tertile 2: OR (95% CI): 1.6 (1.4, 1.9); tertile 3: 2.5 (2.1, 3.1); 1-2 times/wk-tertile 2: OR (95% CI): 1.4 (1.2, 1.6); tertile 3: 1.5 (1.2, 1.8)]. Consumption of AFHFs ≥1 time/wk from each AFHF setting, compared with consumption of any AFHFs <1 time/wk was associated with lower odds of being in higher AHEI-2010 tertiles. Increasing AFHF intake frequency was not associated with odds of overweight or obesity. Eating from on-street vendors ≥1 time/wk was associated with obesity (OR: 1.5; 95% CI: 1.1, 2.0).Conclusions: Consumption of AFHFs was prevalent among Hispanic/Latino adults and was associated with poorer diet quality. Findings may help to identify dietary targets to improve diet quality and prevent obesity in US Hispanics/Latinos. [ABSTRACT FROM AUTHOR]- Published

Background: Healthful diet quality has been associated with a lower risk of metabolic syndrome (MetS) in several populations, but reports on Hispanic and Latino cohorts, grouped or by ethnic background, have been limited and inconsistent.Objective: We aimed to examine diet quality by using the 2010 Alternate Healthy Eating Index [(AHEI) range: 0-110, lowest to highest quality] and its cross-sectional association with MetS and its cardiometabolic components across 6 Hispanic and Latino backgrounds.Methods: We studied 12,406 US Hispanics and Latinos, aged 18-74 y and free of diabetes, from the multicenter, population-based Hispanic Community Health Study/Study of Latinos cohort. Food and nutrients were assessed from two 24-h recalls. MetS was defined by using the 2009 harmonized guidelines. Complex survey procedures were used in multivariable-adjusted linear regression models to test the association of the AHEI with continuous markers and in logistic regression models with MetS as an outcome.Results: The prevalence of MetS was 24.2%. Overall, Hispanics and Latinos had low scores for intakes of sugar-sweetened beverages and fruit juices, whole grains, and fruit and favorable scores for trans fats and nuts and legumes, according to AHEI criteria. Adjusted mean AHEI and its individual components differed by ethnic background (P < 0.001), ranging from 43.0 for Puerto Ricans to 52.6 for Mexicans. Overall, adjusted odds (95% CIs) of having MetS were 22% (9%, 33%) lower for each 10-unit increase in AHEI. This association was modified by ethnic background (P-interaction = 0.03), with significantly lower odds observed only for Mexicans (30%; 95% CIs: 13%, 44%) and Central Americans (42%; 95% CIs: 9%, 64%) for each 10-unit increase in AHEI. AHEI was inversely associated with waist circumference, blood pressure, and glucose among Mexicans and Puerto Ricans and with triglycerides among Mexicans only, and positively associated with HDL cholesterol among Puerto Ricans and Central Americans (all P < 0.05).Conclusions: Diet quality differed by Hispanic or Latino background. Although healthier diet quality was associated with lower odds of MetS in the overall Hispanic and Latino cohort, the association of AHEI and cardiometabolic factors varied by ethnic background. Nutrition-related research and interventions among ethnically diverse groups should consider individual ethnic backgrounds to optimally address diet quality and cardiometabolic health. This trial was registered at clinicaltrials.gov as NCT02060344. [ABSTRACT FROM AUTHOR]- Published

Background: Studies have suggested that the fat mass and obesity- associated (FTO) genotype is associated with individual variability in weight loss in response to diet/lifestyle interventions, but results are inconsistent. Objective: We aimed to provide a summary of the literature evaluating the relation between the FTO genotype and weight loss in response to diet/lifestyle interventions. Design: A search of English-language articles in the PubMed and Embase databases (through 30 April 2015) was performed. Eligible studies were diet/lifestyle weight-loss intervention studies conducted in adults that reported changes in body weight or body mass index (BMI) by the FTO variant rs9939609 (or its proxy). Differences in weight loss between FTO genotypes across studies were pooled with the use of fixed-effect models. Results: A meta-analysis of 10 studies (comprising 6951 participants) that reported the results of additive genetic models showed that individuals with the FTO TA genotype and AA genotype (those with the obesity-predisposing A allele) had 0.18-kg (95% CI: 20.09-, 0.45-kg; P = 0.19; NS) and 0.44-kg (95% CI: 0.09-, 0.79-kg; P = 0.015) greater weight loss, respectively, than those with the TT genotype. A metaanalysis of 14 studies (comprising 7700 participants) that reported the results of dominant genetic models indicated a 0.20-kg (20.43-, 0.04-kg) greater weight loss in the TA/AA genotype than in the TT genotype (P = 0.10). In addition, differences in weight loss between the AA genotype and TT genotype were significant in studies with a diet intervention only, adjustment for baseline BMI or body weight, and several other subgroups. However, the relatively small number of studies limited these stratified analyses, and there was no statistically significant difference between subgroups. Conclusions: This meta-analysis suggests that individuals carrying the homozygous FTO obesity-predisposing allele may lose more weight through diet/lifestyle interventions than noncarriers. Our data provide evidence for genetic variability in response to diet/lifestyle interventions on weight loss, although clinical applications of these findings need further investigations.
