“No sufro, estoy bien/I am not suffering, so I am doing OK”: A mixed method exploration of individual and network-level factors and Type 2 Diabetes Mellitus (T2DM) among Mexican American adults in New York City
2024
The prevalence of type 2 Diabetes Mellitus (T2DM) is 2-3 times greater among Mexican Americans than non-Latino whites, and Mexican Americans are more likely to develop T2DM at younger ages and experience higher rates of complications. Social networks might play a crucial role in both T2DM etiology and management through social support, access to resources, social engagement, and health behavioral norms.
To quantitatively identify the social network features associated with glycated hemoglobin (HbA1c) in a community sample of Mexican immigrants residing in New York City, and to explore the extent to which these quantitative findings converge with qualitative narratives of their lived experiences.
This study used a convergent mixed methods design. To collect personal network data, we used EgoWeb, and obtained 1,400 personal network ties from 81 participants. HbA1c readings were collected using dried blood spots and categorized according to the laboratory criteria of the American Diabetes Association. Additional survey data were collected using Qualtrics software. To investigate the significance of the network-level factors after accounting for the socioeconomic and demographic individual-level factors that the literature indicates to be associated with T2DM, we used a multiple regression model on quantitative data sources. For the qualitative portion of the study, we selected a subset of individuals who participated in the quantitative portion, which represented 500 personal network ties from 25 participants. We conducted in-depth interviews guided by the visualization of these ties to explore who was helpful or difficult in managing their health and health behaviors.
Individual-level indicators associated with lower HbA1c scores were body mass index (β = -0.07, p<0.05), and healthy eating index scores (β = -0.03, p<0.02). The network-level predictor associated with higher HbA1c levels was the percentage of diabetic alters in the network (β = 0.08, p <0.001, with a 25% increase in the percentages associated 2.0 change in HbA1c levels. The qualitative data highlighted that most of the diabetes-related information diffused through the social networks of our participants was related to dietary practices, such as reducing sugar and red meat consumption, eating out less, and reducing portion sizes. Notably, even among those with elevated levels and diabetes-related health complications, HbA1c was not considered a part of the lay descriptions of good health since they were not \"suffering.\" Participants regarded doctors as the ultimate authority in diabetes care, even if they had supportive members in their personal networks.
Our study provides quantitative evidence for the significant role of diabetic network members in the etiology and management of T2DM among Mexican Americans. Our qualitative findings suggest important ley terms for T2DM management and the importance of physicians, which could be included in in future social networks studies seeking to diffuse diabetes-related health information for T2DM prevention and management efforts in this population.

Cross-Sectional Analysis of Sugar-Sweetened Beverage Consumption, Food Security, and Nativity Among Adults: Associations from National Health and Nutrition Examination Survey 2007–2020
2025
Background/Aims: Immigrant populations face unique dietary challenges influenced by food security and acculturation, particularly regarding sugar-sweetened beverages (SSBs). This study examines the interplay of nativity and food security on SSB consumption patterns. Methods: Data from the National Health and Nutrition Examination Survey (NHANES) 2007–2020 (N = 23,331) were analyzed in this cross-sectional study. SSB consumption was assessed through 24 h dietary recalls. Food security was categorized as high/marginal or low/very low, and nativity as U.S.-born or foreign-born. Stratified regression models by sex evaluated associations between nativity, food security, and SSB consumption. Results: U.S.-born adults with low food security had the highest sugar intake (men: β = 27.5, 95% CI [14.8, 40.3]; women: β = 30.4, 95% CI [11.0, 49.7]) and SSB consumption (men: β = 14.7, 95% CI [11.2, 18.3]; women: β = 23.6, 95% CI [15.2, 31.9]). Conclusions: The findings highlight associations that suggest the importance of culturally tailored interventions targeting vulnerable groups to address disparities in SSB consumption influenced by food security and nativity.

Interest in studying the impact of acculturation on immigrant health has increased in tandem with the growth of the Latino population in the United States. Linear assimilation models continue to dominate public health research despite the availability of more complex acculturation theories that propose multidimensional frameworks, reciprocal interactions between the individual and the environment, and other acculturative processes among various Latino groups. Because linear and unidimensional assessments (e.g., nativity, length of stay in the United States, and language use) provide constricted measures of acculturation, the rare use of multidimensional acculturation measures and models has inhibited a more comprehensive understanding of the association between specific components of acculturation and particular health outcomes. A public health perspective that incorporates the roles of structural and cultural forces in acculturation may help identify mechanisms underlying links between acculturation and health among Latinos.

Background
Latinos in the United States (U.S.) represent a heterogeneous minority population disproportionally impacted by obesity. Colombians in the U.S. are routinely combined with other South Americans in most obesity studies. Moreover, most studies among Latino immigrants in the U.S. solely focus on factors in the destination context, which largely ignores the prevalence of obesity and contextual factors in their country of origin, and warrant transnational investigations.
Methods
Using 2013-17 data from the New York City Community Health Survey (NYC CHS, U.S.) and the National Survey of the Nutritional Situation (ENSIN, Colombia), Colombians that immigrated to the U.S. and are living in NYC (n = 503) were compared to nonimmigrant Colombians living in their home country (n = 98,829). Prevalence ratios (PR) for obesity (BMI ≥ 30 kg/m
2
) by place of residence were estimated using multivariable logistic regression adjusting for socio-demographic characteristics and daily consumption of sugar-sweetened beverages.
Results
The prevalence of obesity was 49% greater for immigrant Colombians living in NYC when compared to nonimmigrant Colombians living in in their home country (PR = 1.49; 95% CI 1.08, 2.07). Colombian immigrant men in NYC were 72% more likely to have obesity compared to nonimmigrant men living in their home country (PR = 1.72; 95% CI 1.03, 2.87). No significant differences were found in the adjusted models among women.
Conclusions
Colombian immigrants in NYC exhibit a higher prevalence of obesity compared to their nonimmigrant counterparts back home and sex strengthens this relationship. More obesity research is needed to understand the immigration experience of Colombians in the U.S. and the underlying mechanisms for sex difference. Public health action focused on women in Colombia and both Colombian men and women immigrants in the U.S. is warranted to avert the long-term consequences of obesity.

Background
Immigrants are disproportionally impacted by HIV infection in Europe and in Spain. Immigrants are also identified as a vulnerable population during economic crises. Various socioeconomic barriers hinder HIV-positive immigrants from accessing healthcare services in the host country. As a result of the 2008 financial crisis, Spain has implemented multiple austerity measures, one of which was the enactments of Royal Decree Law (RDL) 16/2012 and Royal Decree (RD) 1192/2012 which abolished universal healthcare coverage. In this context, this study examined: 1) Participants’ mixed experiences in accessing health care after the enactment of 2012 RDL and RD, and 2) Distress felt by the participants and their experiences as HIV-positive immigrants living in Spain.
Methods
Participants were recruited through a nongovernmental organization (NGO) during routine visits at the center. A total of 12 participants were interviewed to reach data saturation. Participants were HIV-positive immigrants living in Spain for 1 or more years, allowing for substantial experience with navigating the healthcare system. Thematic analysis was performed to identify common themes in participants’ experiences living as HIV-positive individuals in Spain and in accessing healthcare.
Results
Four primary themes were identified. The primary systemic barrier to accessing health care encountered by participants was the inability to fulfill the requirement of having proof of registration in an Autonomous Community for the required time period, thus not being able to apply for a public health insurance card and utilize free care services. Participants identified a positive impact of third party (NGO, social worker, friend/family member) guidance on their experience of applying for a public health insurance card. Participants expressed experiencing emotional or physical (eg, side effects of medication) distress in adapting to life as HIV-positive individuals. Participants also identified experiencing discrimination while living as HIV-positive immigrants in Spain.
Conclusions
HIV-positive immigrants are underserved in Spain. They encounter systemic barriers while accessing healthcare services, and experience fear and/or discrimination. The study underscores the role of NGOs in helping HIV-positive immigrants navigate the healthcare system. More research is needed on comprehensive approaches to address healthcare needs of HIV-positive immigrants in Spain.

Latinos have high rates of type 2 diabetes mellitus (T2DM) yet are characterized as having health-promoting social networks. The impacts of COVID-19 on personal networks were complex, especially in urban areas with high proportion of immigrants such as the Bronx in NYC. Our objective was to test the extent to which network characteristics increase vulnerability or resiliency for glycemic control based on data gathered from Mexican-origin Bronx dwellers. We used two-wave panel study analyzing self-reported personal social networks (

; 600

) and HbA1c levels via dried blood spots in 2019, before the COVID-19 pandemic, and in 2021, a time after initial lockdowns and when the pandemic was still ravaging the community of study. Regression models adjusted for individual-level variables including sociodemographic and health indicators (i.e., physical health including COVID-19 and mental health). We found that an increase in the proportion of network members with diabetes predicted an increase in participant’s HbA1c levels from 2019 to 2021 (
β
=0.044,
p
< 0.05). Also, a greater proportion of network members consuming “an American diet” in 2019 predicted a decrease in participant’s HbA1c levels (
β
=−0.028,
p
< 0.01), while a greater proportion of network members that encouraged participants’ health in 2019 predicted an increase in participant’s HbA1c levels (
β

p
< 0.05). Our study sheds light on specific social network characteristics relevant to individual diabetes outcomes, including potential longitudinal mechanistic effects that played out at the peak of the COVID-19 crisis.

Current treatment of metabolic dysfunction-associated steatotic liver disease focuses on adjusting patients’ lifestyles, including promoting weight loss and physical activity. Here, we suggest adopting a holistic preventive hepatology approach encompassing social nutrition, social prescribing and broader societal changes to facilitate individuals’ engagement with behavioural modifications.
Ivancovsky-Wajcman et al. outline the need for a holistic preventive hepatology approach, involving social nutrition and social prescribing, to address the public health threat of metabolic dysfunction-associated steatotic liver disease (MASLD). They argue that this will facilitate individuals’ engagement in behavioural modifications to treat MASLD.

Healthcare discrimination is an important barrier to accessing services among Latino populations in the United States. However, few validated scales have been developed to systematically examine this issue. In this study, we evaluated the validity and reliability of a bilingual healthcare discrimination scale in a sample of churchgoing Latino adults in Los Angeles, California. The study sample included 336 participants (foreign-born: 250; US-born: 86) who attended 12 Catholic churches in Los Angeles. Psychometric testing of the 7-item healthcare discrimination (HCD) scale included internal consistency; split-half reliability; convergent, discriminant, and predictive validity; and confirmatory factor analyses. The HCD had relatively high internal consistency (full sample Cronbach’s α = 0.92; foreign-born: 0.91; US-born: 0.92) and showed good convergent and discriminant validity, as it was moderately correlated with the depression scale (full sample r = 0.28, p < 0.001) and weakly correlated with the acculturation scale (full sample r = 0.15, p = 0.008). Confirmatory factor analyses yielded further support for a one-factor solution. Our study finds that the HCD is a valid and reliable scale for use among churchgoing Latino adult populations in the United States. Future studies should examine the psychometric properties of the HCD among Latinos of diverse backgrounds, geographic locations, religious beliefs, and languages.

Segmented Assimilation
2017
Segmented assimilation theory posits that immigrants experience distinct paths of assimilation. Using cluster analysis and data from the National Latino and Asian American Survey, this study sought to apply this theory in relation to obesity among Latinos. Four clusters emerged: a “second-generation classic,” a “third-generation classic,” an “underclass,” and a “segmented assimilation” pattern. In analyses controlling for sociodemographic confounders (eg, age), second-generation classic individuals had higher odds of obesity (odds ratio = 2.70, 95% confidence interval = 1.47-4.93) relative to the segmented pattern. Similarly, third-generation classic individuals had higher odds of obesity (odds ratio = 3.23, 95% confidence interval = 1.74-6.01) compared with segmented assimilation individuals.

“There is No Time” to be a Good Biocitizen: Lived Experiences of Stress and Physical Activity Among Mexican Immigrants in New York City
2024
This paper explores the ways in which Mexican immigrants experience, narrate, and describe stress and the extent to which it impacts their efforts at engaging in physical activity using a biocitizenship framework. Data were derived from a mixed-method study among Mexicans living in New York City recruited from a large Catholic church. The qualitative sample of 25 participated in quantitative and qualitative components of the study and as such we include some of these quantitative indicators as descriptors. Our main qualitative findings reveal that study participants experience stress and time constraint as factors that contribute to the waning of their physical and mental well-being. As such, time constraints for many of our participants were among the factors that contributed to high perceived levels of stress. They attributed this to their difficulty maintaining a physically active lifestyle due to factors like the fast-paced lifestyle in New York, working long hours, and not having enough time to exercise, though some important differences in narratives were noted across gender. Findings have implications for interventions aimed at improving the health of immigrants in general and Mexican immigrants in New York City specifically.
Plain Language Summary
Stress is a common reaction we all experience in our daily lives, both physically and emotionally. However, when stress persists, it can have negative effects on our health. To better understand the experiences of Mexican immigrants living in NYC, we conducted individual interviews with 25 participants. We explored their thoughts on stress, physical activity, and life in NYC, as well as how the people around them influenced their efforts. The narratives shared by the participants revealed that Mexican immigrants perceive stress as having a significant impact on their physical and mental well-being. Specifically, discussions about stress affecting their health were linked to factors such as time constraints, long working hours, and not having enough time to exercise. These findings indicate that although participants desired a healthy lifestyle, they encountered barriers that hindered their ability to engage in physical activity. Additionally, our study highlighted that men and women experience stress differently. Women often felt stressed due to household responsibilities like cooking, whereas men experienced stress related to financial obligations. Despite these gender differences, both men and women described how stress negatively affected their overall health. These findings suggest that public health interventions and programs could focus on promoting physical activity to enhance the physical and mental well-being, but these would need to be tailored to fit the needs of Mexican immigrants in New York City and other similar communities.
