Résumé : Background
Caribbean Latino adults have disproportionately high prevalence of chronic disease; however, underlying mechanisms are unknown. Unique gut microbiome profiles and relation to dietary quality may underlie health disparities.
To examine the dietary quality of an underrepresented group of Caribbean Latino older adults with high prevalence of chronic disease; characterize gut microbiome profiles in this cohort; determine associations between dietary quality, gut microbiome composition, and short-chain fatty acid (SCFA) production; examine associations of clinical factors (body mass index, type 2 diabetes [T2D] status, and laxative use) with gut microbiome composition.
The study design was cross-sectional.
Recruitment and interviews occurred at the Senior Center in Lawrence, MA, from September 2016-September 2017. A total of 20 adults aged ≥50 years, self-identified of Caribbean Latino origin, without use of antibiotics in 6 months or intestinal surgery were included in the study.
Exposure and outcome measures
Diet was assessed by two, 24-hour recalls and dietary quality was calculated using the Healthy Eating Index 2015 and the Mediterranean Diet Score. The gut microbiome was assessed by 16S rRNA sequencing and fecal SCFA content. Anthropometrics (ie, weight and height) were measured by a trained interviewer, and self-reported laxative use, and other self-report health outcomes (ie, T2D status) were assessed by questionnaire.
Faith Phylogenetic Diversity (alpha diversity) and unique fraction metric, or UniFrac (beta diversity) and nonphylogenetic metrics, including Shannon diversity index (alpha diversity) were calculated. Spearman correlations and group comparisons using Kruskal-Wallis test between alpha diversity indexes and nutrient intakes were calculated. Patterns in the microbiome were estimated using a partitioning around medoids with estimation of number of clusters, with optimum average silhouette width. Log odds were calculated to compare predefined nutrients and diet score components between microbiome clusters using multivariable logistic regression, controlling for age and sex. Pearson correlation was used to relate SCFA fecal content to individual nutrients and diet indexes. Final models were additionally adjusted for laxative use. Differences in lifestyle factors by gut microbiome cluster were tested by Fisher's exact test.
Generally, there was poor alignment of participants diets to either the Mediterranean Diet score or Healthy Eating Index 2015. Range in the Healthy Eating Index 2015 was 36 to 90, where only 5% (n=1) of the sample showed high adherence to the Dietary Guidelines for Americans. Mediterranean Diet scores suggested low conformance with a Mediterranean eating pattern (score range=2 to 8, where 45% scored ≤3 [poor adherence]). The gut microbiome separated into two clusters by difference in a single bacterial taxon: Prevotella copri (P copri) (permutational multivariate analysis of variance [PERMANOVA] R2=0.576, ADONIS function P=0.001). Significantly lower P copri abundance was observed in cluster 1 compared with cluster 2 (Mann-Whitney P Conclusions
Two unique microbiome profiles, identified by abundance of P copri, were identified among Caribbean Latino adults. Microbiome profiles and SCFA content were associated with diet, T2D, and lifestyle. Further research is needed to determine the role of P copri and SCFA production in the risk for chronic disease and associated lifestyle predictors.

Multilevel church-based interventions may help address racial/ethnic disparities in obesity in the United States since churches are often trusted institutions in vulnerable communities. These types of interventions affect at least two levels of socio-ecological influence which could mean an intervention that targets individual congregants as well as the congregation as a whole. However, the extent to which such interventions are developed using a collaborative partnership approach and are effective with diverse racial/ethnic populations is unclear, and these crucial features of well-designed community-based interventions.
The present systematic literature review of church-based interventions was conducted to assess their efficacy for addressing obesity across different racial/ethnic groups (eg, African Americans, Latinos).
Data Sources and Extraction
In total, 43 relevant articles were identified using systematic review methods developed by the Center for Disease Control and Prevention (CDC)s Task Force on Community Preventive Services. The extent to which each intervention was developed using community-based participatory research principles, was tailored to the particular community in question, and involved the church in the study development and implementation were also assessed.
Although 81% of the studies reported significant results for between- or within-group differences according to the study design, effect sizes were reported or could only be calculated in 56% of cases, and most were small. There was also a lack of diversity among samples (eg, few studies involved Latinos, men, young adults, or children), which limits knowledge about the ability of church-based interventions to reduce the burden of obesity more broadly among vulnerable communities of color. Further, few interventions were multilevel in nature, or incorporated strategies at the church or community level.
Church-based interventions to address obesity will have greater impact if they consider the diversity among populations burdened by this condition and develop programs that are tailored to these different populations (eg, men of color, Latinos). Programs could also benefit from employing multilevel approaches to move the field away from behavioral modifications at the individual level and into a more systems-based framework. However, effect sizes will likely remain small, especially since individuals only spend a limited amount of time in this particular setting.

Résumé : Higher frequency of eating outside the home can be an unhealthy behavior that may contribute to higher rates of obesity among Latinas, a disproportionately affected group. There is a growing need to understand potentially modifiable factors (eg, dispositional mindfulness, self-efficacy, nutrition knowledge) associated with higher frequency of eating outside the home in this population. This study assessed associations of cognitive factors (ie, dispositional mindfulness, self-efficacy of eating and purchasing healthy foods, nutrition knowledge) with frequency of eating out among Latinas. A secondary analysis was performed of data from a cross-sectional study of Latinas between February and May 2015. The study comprised a convenience sample of 218 Spanish- or English-literate Latinas, between the ages of 18 and 55 years, who lived in South or East Los Angeles and self-identified as the primary person responsible for grocery shopping in the household. Most participants identified as foreign-born Mexican Americans. Frequency of eating out was assessed as the outcome variable, and three cognitive variables (mindfulness disposition, self-efficacy, nutrition knowledge) served as independent variables. Multinomial models assessed the association between cognitive factors and frequency of eating out. Models were adjusted for age, English-speaking ability, income, having an obesity-related disease (ie, overweight or obesity, diabetes, high blood pressure, cardiovascular disease), household size, and education level. For every 1-unit increase in mindfulness disposition, the risk of a participant eating out every week compared with every month decreased by a factor of 0.42 (relative risk ratio [RRR] = 0.58, P Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=https://www.sciencedirect.com/science/a [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=267080

Mots-clés : Rappel alimentaire de 24 heures Multiple Source Method National Cancer Institute method Résumé : The Multiple Source Method (MSM) and the National Cancer Institute (NCI) method estimate usual dietary intake from short-term dietary assessment instruments, such as 24-hour recalls. Their performance varies according to sample size and nutrients distribution. A comparison of these methods among a multiethnic youth population, for which nutrient composition and dietary variability may differ from adults, is a gap in the literature.
To compare the performance of the NCI method relative to MSM in estimating usual dietary intakes in Hispanic/Latino adolescents.
Data derived from the cross-sectional population-based Hispanic Community Health Study/Study of Latino Youth, an ancillary study of offspring of participants in the adult Hispanic Community Health Study/Study of Latino Youth cohort. Dietary data were obtained by two 24-hour recalls.
One thousand four hundred fifty-three Hispanic/Latino youth (aged 8 to 16 years) living in four urban US communities (Bronx, NY; Chicago, IL; Miami, FL; and San Diego, CA) during 2012 through 2014.
Main outcome measures
The NCI method and the MSM were applied to estimate usual intake of total energy, macronutrients, minerals and vitamins, added sugar, and caffeine.
Mean, standard deviation, minimum and maximum values, coefficient of variation, variance ratio, and differences between NCI and MSM methods and the 2-day mean were estimated in several percentiles of the distribution, as well as concordance correlation coefficients and Bland-Altman plot analysis.
The distributions of all nutrients studied were very similar between NCI and MSM. The correlation between NCI and MSM was >0.80 for all nutrients (P
Overall, both MSM and NCI method provided acceptable estimates of the usual intake distribution using 24-hour recall, and they better represented the usual intake compared with 2-day mean, correcting for intraindividual variability.

Résumé : Background: Black women suffer disproportionately poor birth outcomes, including increased morbidity and mortality for mothers and babies, in the United States (US).
Objective: The purpose of this study is to explore racial/ethnic differences in women receiving prenatal care in Federally Qualified Health Centers (FQHCs).
Methods: We conducted a retrospective secondary analysis of 17,086 prenatal women receiving care at FQHCs for the period 2012-2017.
Results: Compared to both White and Latinx pregnant women, Black women were less likely to initiate prenatal care in the first trimester and less likely to be partnered during their pregnancy. Black women are at greater risk for elevated pre-pregnancy body mass index (BMI) compared to White women and more at risk for hypertension compared to Latinx women.
Conclusion: This study highlights prenatal differences in Black, White and Latinx women. Education on the importance of first trimester entry into prenatal care, adequate social support and healthy nutrition are important to include in the care of Black women of childbearing age.
