Background: Bilingualism may protect against cognitive aging and delay the onset of dementia. However, studies comparing monolinguals and bilinguals on such metrics have produced inconsistent results complicated by confounding variables and methodological concerns.
Methods: We addressed this issue by comparing cognitive performance in a more culturally homogeneous cohort of older Spanish-speaking monolingual (n = 289) and Spanish-English bilingual (n = 339) Mexican-American immigrants from the Sacramento Longitudinal Study on Aging.
Results: After adjusting for demographic differences and depressive symptoms, both groups performed similarly at baseline on verbal memory but the bilingual group performed significantly better than the monolingual group on a cognitive screening test, the Modified Mini-Mental State Examination (3MS; p < 0.001). Group differences on the 3MS were driven by language/executive and language/praxis factors. Within the bilingual group, neither language of testing nor degree of bilingualism was significantly associated with 3MS or verbal memory scores. Amongst individuals who performed in the normal or better range on both tests at baseline and were followed for an average of 6 years, both monolinguals and bilinguals exhibited similar rates of cognitive decline on both measures.
Conclusions: These findings suggest that bilingualism is associated with modest benefits in cognitive screening performance in older individuals in cross-sectional analyses that persist across longitudinal analyses. The effects of bilingualism should be considered when cognitively screening is performed in aging immigrant populations.

Background: This study investigates acculturative stress and its impact on psychological distress among Mexican immigrant women in the United States, with a particular focus on contextual factors shaping these acculturative stress experiences. It also seeks to provide actionable insights to address Mexican immigrant women's mental health needs.
Methods: Using the data from a total of 257 Mexican immigrant women in the National Latino Asian American Survey (NLAAS), path analysis was conducted to examine the relationships between acculturative stress, psychological distress, and various contextual factors.

Background: The race-based traumatic stress model proposes that discrimination elicits trauma-related symptoms. Cumulative discriminatory experiences and subsequent trauma symptoms may lead to prenatal inflammation, with far reaching consequences for the health of a mother and her child.
Methods: Latina mothers, primarily of Mexican and Central American heritage ( = 150), completed the Everyday Discrimination Scale and the Traumatic Avoidance subscale of the Inventory of Depression and Anxiety Symptoms-II during pregnancy (24-32 weeks).

Background: Many present analyses of Hispanic/Latino populations in epidemiologic research aggregate all members of this ethnic group, despite immense diversity in genetic backgrounds, environment, and culture between and across Hispanic/Latino background groups. Using the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), we examined the role of self-identified background group and genetic ancestry proportions in gene-environment interactions influencing the relationship between body mass index (BMI) and a polygenic score for BMI (PGS).
Methods: Weighted univariate and multivariable generalized linear models were executed to compare the effects of environmental variables identified by McArdle et al.

The COVID-19 pandemic was associated with decreases in moderate-to-vigorous physical activity and increases in sedentary time for children and adults, and there is some evidence that Latino populations were particularly affected. This article leverages a two-wave panel, mixed-method social network dataset collected before and during the pandemic with Mexican American immigrants living in New York City to examine social networks and other factors associated with physical activity and explore participants' perceptions about how the pandemic affected their physical activity. Participants (n = 49) completed in-person, egocentric social network interviews between January and June 2019 and virtual follow-up egocentric social network interviews between May and November 2021.
