Prevalence and predictors of overweight and obesity in Brazilian immigrants in Massachusetts

Sociodemographic Variables Associated with Self-reported Access to Mental Healthcare Among Brazilian Immigrant Women in the U.S

Brazilians are a rapidly growing immigrant population in the United States (U.S.), yet little is known about their mental health and access to mental healthcare. Our goal was to access associations between the pursuit of- and access to-mental healthcare with mental health status and socio-demographic characteristics among Brazilian immigrant women. We conducted an online survey of Brazilian women aged 18 or older who reported being born in Brazil and currently residing in the U.S. We recruited respondents via Brazilian cultural media, community organizations serving Brazilian immigrants, and social media. We assessed respondents' perceived access to mental healthcare, self-reported mental health (CES-D-10), and socio-demographic characteristics and conducted multivariable logistic regression. Our analysis included 351 participants. Half (52%) had CES-D-10 scores indicating high levels of depressive symptomatology. A third (33%) reported seeking care for their mental health in the past 12 months, 87% of whom reported obtaining care. Results of multivariable logistic regression determined that respondents who sought mental healthcare were more likely to have higher CES-D-10 scores (OR = 1.09, 95% CI 1.03-1.15), very low incomes (<$10,000 per year; OR = 0.34, 95% CI 0.12-0.96), and were marginally more likely to have a primary care provider (OR = 2.11, 95% CI 1.00, 4.46). We found that despite a high level of depressive symptomology, only one-third reported accessing care. While difficulty accessing care for mental issues is a widespread issue, our findings suggest that efforts are needed to ameliorate mental health issues for Brazilian women to reduce systemic, interpersonal, and individual barriers to seeking care among the 13% who sought healthcare but were unable to receive it.

The (in)visible Brazilians: A perspective review on the need for brain health and dementia research with Brazilian immigrants in the United States

Introduction

The Brazilian population in the United States (U.S.), a Latinx subgroup, is rapidly growing and aging but remains underrepresented in U.S. health research. In addition to group-specific genetic and environmental risks, Brazilian immigrants and their offspring in the U.S. likely have cumulative risks for health inequities.It is estimated that 71% of Brazilian immigrants in the U.S. are undocumented, which may limit healthcare access/utilization. Furthermore, mental health is reported as a health priority by Brazilian immigrants in the U.S., and there is a lack of research on Alzheimer's disease and related dementia (AD/ADRD) in this population.

Methods

We reviewed the scientific literature using traditional (e.g., PubMed) sources and databases generated by U.S. and Brazilian governments, as well as international organizations, and press articles.

Results

This perspective review lists recommendations for researchers, health providers, and policymakers to promote greater inclusion of U.S. Brazilian populations in health research and care. The review identifies research areas in need of attention to address health inequities and promote mental/brain health in Brazilian immigrants and their offspring living in the U.S. These research areas are: 1) epidemiological studies to map the prevalence and incidence of mental/brain health conditions; 2) research on aging and AD/ADRD risk factors among Brazilian populations in the U.S.; and 3) the need for greater representation of U.S-residing Brazilian population in other relevant research areas involving genetics, neuropathology, and clinical trials.

Conclusions

The recommendation and research efforts proposed should help to pave the way for the development of community-engagement research and to promote mental/brain health education, improvement of mental/brain health and AD/ADRD services, and the development of culturally-informed intervention to the U.S.-residing Brazilian communities.

HIGHLIGHTS

The Brazilian population in the United States is growing but is underrepresented in U.S. health research.Approximately 71% of Brazilian immigrants in the United States are undocumented, with an increased risk for health inequities.Mental health is reported as a central health priority by Brazilian immigrants in the United States.There is a lack of research on Alzheimer's disease and other dementias (ADRD) in Brazilian immigrants in the United States.Epidemiological research is needed to map the prevalence/incidence of mental health conditions and ADRD risk factors among Brazilian immigrants in the United States.

Systematic Review and Meta-Analysis of Metabolic Syndrome and Its Components in Latino Immigrants to the USA

The Metabolic Syndrome (MetS) is an increasingly prevalent condition globally. Latino populations in the USA have shown an alarming increase in factors associated with MetS in recent years. The objective of the present systematic review was to determine the prevalence of MetS and its risk factors in immigrant Latinos in the USA and perform a meta-analysis of those prevalence. The review included cross-sectional, cohort, or case−control studies involving adult immigrant Latinos in the USA, published during the period 1980−2020 in any language. Studies involving individuals who were pregnant, aged <18 years, immigrant non-Latinos, published outside the 1980−2020 period, or with other design types were excluded. The Pubmed, Web of Science, Embase, Lilacs, Scielo, and Google Scholar databases were searched. The risk of bias was assessed using the checklists of the Joanna Briggs Institute. The review included 60 studies, and the meta-analysis encompassed 52 studies. The pooled prevalence found for hypertension, diabetes, general obesity, and abdominal obesity were 28% (95% Confidence Interval (CI): 23−33%), 17% (95% CI: 14−20%), 37% (95% CI: 33−40%), and 54% (95% CI: 48−59%), respectively. The quality of the evidence of the primary studies was classified as low or very low. Few studies including immigrants from South America were identified. Further studies of those immigrants are needed due to the cultural, dietary, and language disparities among Latin American countries. The research protocol was registered with the Open Science Framework (OSF).

Gut Microbiota Profile and Its Association with Clinical Variables and Dietary Intake in Overweight/Obese and Lean Subjects: A Cross-Sectional Study

We aimed to differentiate gut microbiota composition of overweight/obese and lean subjects and to determine its association with clinical variables and dietary intake. A cross-sectional study was performed with 96 overweight/obese subjects and 32 lean subjects. Anthropometric parameters were positively associated with Collinsella aerofaciens, Dorea formicigenerans and Dorea longicatena, which had higher abundance the overweight/obese subjects. Moreover, different genera of Lachnospiraceae were negatively associated with body fat, LDL and total cholesterol. Saturated fatty acids (SFAs) were negatively associated with the genus Intestinimonas, a biomarker of the overweight/obese group, whereas SFAs were positively associated with Roseburia, a biomarker for the lean group. In conclusion, Dorea formicigenerans, Dorea longicatena and Collinsella aerofaciens could be considered obesity biomarkers, Lachnospiraceae is associated with lipid cardiovascular risk factors. SFAs exhibited opposite association profiles with butyrate-producing bacteria depending on the BMI. Thus, the relationship between diet and microbiota opens new tools for the management of obesity.

Health Conditions and Dietary Intake Among Brazilian Immigrants in the United States of America

Immigration can improve economic status and access to education compared to the country of origin, but it challenges access to health and preventive care. Assess Brazilian immigrants' overall health conditions and dietary intake in New Jersey (US). This pilot study assessed health conditions and dietary intake. Brazilians immigrants were interviewed through their communities. Trained dietitians interviewed them using a questionnaire and three days of 24H recall. Dietary intake was analyzed using the Nutrition Data System for Research software. A sample of 118 individuals completed the protocol, majority female and overweight/obese, living in the US for 11.3 years with 21.1% declaring having Noncommunicable Diseases. The average number of daily meals was 2.20 ± 1.04. Energy intake does not correlate with time in the US. Obesity, dyslipidemia, and hypertension are the most prevalent Noncommunicable Diseases, demanding interventions that include managing saturated fat, cholesterol, and sodium intake.

High Prevalence of Obesity but Low Physical Activity in Children Aged 9-11 Years in Beijing

OBJECTIVE

To investigate the prevalence and associated factors of childhood overweight/obesity in the Shunyi district of Beijing, China.

METHODS

This study adopted a cross-sectional survey and included 10,855 children aged 6-18 years in the Shunyi district of Beijing, China. Analyses were stratified by age group (6-8, 9-11, 12-14, and 15-18 years).

RESULTS

The prevalence of overweight and obesity among children aged 6-18 years was high with 17.62% and 29.05% in boys, 17.57% and 18.04% in girls, respectively. Both boys and girls aged 9-11 years had the highest rate of obesity in comparison with the other age groups, though the differences in children aged 9-11 years and 12-14 years were not statistically significant. Compared with age 6-8 years, age 9-11 years (OR=1.59, 95% CI 1.41-1.79, P<0.01) and 12-14 years (OR=1.26, 95% CI 1.48-1.73, P<0.01) were independently positively associated with obesity. Importantly, in all subjects, the percentages of being physically active (exercise time ≥120 minutes/week) were lower in children aged 9-11 years in comparison to children in other age groups. This phenomenon remained when this comparison was performed respectively in the normal-weight, overweight, and obesity groups. Even after adjustment for other potential confounders, the probability of being physically active (exercise time ≥120 minutes/week) was lower in children aged 9-11 years (OR=0.86, 95% CI 0.78-0.94, P<0.01), but higher in children aged 12-14 years (OR=1.91, 95% CI 1.69-2.17, P<0.01) and aged 15-18 years (OR=2.22, 95% CI 1.85-2.66, P<0.01), when compared with children aged 6-8 years.

CONCLUSION

Children aged 9-11 years had a higher prevalence of obesity, but a lower percentage of being physically active. Targeted intervention programs in this key group are needed to address this problem in China.
