Socio-Cultural Subgroups of Latina/o Immigrants: A Latent Profile Analysis

Socio-cultural factors, such as familismo, social support, machismo, and multigroup ethnic identity, are strongly associated with Latina/o immigrants' alcohol misuse and depressive symptoms. However, research has rarely explored whether unobserved groups of Latina/o immigrants with similar socio-cultural factors exist. Latent Profile analysis can illuminate which subgroups to target, or which socio-cultural factors need to be supported, to have an impact on the prevention and treatment of alcohol use and/or depression in the Latina/o immigrant population. Cross sectional data from on ongoing longitudinal investigation was utilized (N= 518 Latina/o adults living in Miami-Dade County, Florida and have immigrated to the US within one year prior to assessment). Latent Profile Analyses (LPA) were conducted utilizing validated measures of familismo, social support, neighborhood collective efficacy, ethnic identity, machismo, caballerismo, and marianismo. The LPA revealed three, significantly different profiles: (1) low socio-cultural protection (n=155, 29.98%), (2) high socio-cultural protection (n=21, 4.06%), and (3) high socio-, low-cultural protection (n=341, 65.96%). Profile membership was associated significantly with immigrant documentation status, education level, and past family history of substance use. Results indicate that Latina/o immigrants in the low socio-cultural protection group had significantly higher alcohol use compared to high socio-, low cultural protection group. No significant differences were found for depressive symptoms. We discuss implications of our findings and encourage researchers to continue to unpack the complexities associated with socio-cultural factors and Latina/o mental and behavioral health. Specifically, research should focus on socio-cultural factors can provide protection from negative health outcomes and increase resiliency among this population.

Immigration Stress among Recent Latino Immigrants: The Protective Role of Social Support and Religious Social Capital

Religious institutions can be a source of support for recent Latino immigrants struggling to adjust to a new culture. For undocumented immigrants, who are often marginalized from other formal institutions, they may symbolize a place of refuge and hope through supportive social networks that mitigate common challenges such as social isolation and other forms of immigration stress. This cross-sectional study examined the impact of religious social capital and social support on immigration stress among documented and undocumented recent Latino immigrants (N = 408). Religious social capital was associated with higher levels of social support, while social support was protective against immigration stress. Social support mediated associations between religious social capital and immigration stress, but only among undocumented immigrants. Findings suggest religious social capital may be a particularly useful resource for undocumented immigrants, aiding in the provision of social support and in decreasing levels of immigration stress. Future research directions and implications for culturally tailored service delivery are presented.

Diffusing innovative road safety practice: A social network approach to identifying opinion leading U.S. cities

OBJECTIVE

This study sought to identify opinion-leading U.S. cities in the realm of safe transportation systems by surveying road safety professionals and asking them to identify places that served as models for road safety.

METHODS

Using a purposive sampling methodology, we surveyed professionals employed in road safety-related professions (e.g., transportation engineering, planning, public health, law enforcement, and emergency response). Using 183 professionals' complete responses, we carried out social network analysis to both describe the structure of intermunicipal advice-seeking patterns among road safety professionals and identify those municipalities with relatively high degrees of influence.

RESULTS

We discovered a large intermunicipal monitoring network related to improving road user safety. Half of the network ties (50.4%) crossed regional U.S. census boundaries. Social network statistics informed the identification of 7 opinion-leader and 4 boundary-spanning municipalities.

CONCLUSIONS

This study indicated a large intermunicipal monitoring network, half of which crossed regional boundaries. Road safety professionals have formed a country-spanning example-following network on the topic of improving road user safety in the United States. Researchers and intervention teams can tap into this network to accelerate the uptake and spread of evidence-based road safety practices.

Drinking and Driving among Recent Latino Immigrants: The Impact of Neighborhoods and Social Support

Latinos are disproportionately impacted by drinking and driving arrests and alcohol-related fatal crashes. Why, and how, these disparities occur remains unclear. The neighborhood environments that recent Latino immigrants encounter in their host communities can potentially influence health behaviors over time, including the propensity to engage in drinking and driving. This cross-sectional study utilizes a sample of 467 documented and undocumented adult recent Latino immigrants in the United States to answer the following research questions: (a) How do neighborhood-level factors, combined with social support, impact drinking and driving risk behaviors?; and (b) Does acculturative stress moderate the effects of those associations? Results indicate neighborhood-level factors (informal social control and social capital) have protective effects against drinking and driving risk behaviors via the mediating mechanism of social support. Acculturative stress moderated associations between neighborhood informal social control and social support, whereby the protective effects of informal social control on social support were not present for those immigrants with higher levels of acculturative stress. Our findings contribute to the limited knowledge of drinking and driving among Latino immigrants early in the immigration process and suggest that, in the process of developing prevention programs tailored to Latino immigrants, greater attention must be paid to neighborhood-level factors.

Can social contagion help global health 'jump the shark'? Comment on "how to facilitate social contagion?"

The instrumental use of social networks has become a central tenet of international health policy and advocacy since the Millennium project. In asking, 'How to facilitate social contagion?', Karl Blanchet of the London School of Hygiene and Tropical Medicine therefore reflects not only on the recent success, but also hints to growing challenges; the tactics of partnerships, alliances and platforms no longer seem to be delivering at the same rate and maybe reversing. A better understanding of how social networks work may therefore be needed to strengthen a tactical instrument that has been used to remarkable recent effect. But in focusing on the unbounded rhetoric and narrative options of Global Health, the danger will surely be on missing the fundamental factors constraining network growth. Future growth will depend on understanding these constraints, and Global Health may do well to think of social networks not only instrumentally, but also analytically in terms of the strategic contexts and environments in which such instruments are deployed.

Can international health programmes be sustained after the end of international funding: the case of eye care interventions in Ghana

BACKGROUND

There is general agreement amongst major international policy makers that sustainability is a key component of health interventions in developing countries. However, there is little evidence on the factors enabling or constraining sustainability. Diffusion of innovation theory can help explain how the continuation of activities is related to the attributes of innovations. Innovations are characterised by five attributes: (i) relative advantage; (ii) compatibility; (iii) complexity; (iv) triability; and (v) observability. An eye care programme was selected as a case study. The programme was implemented in the Brong Ahafo region of Ghana and had been funded over a ten-year period by an international organisation.

METHODS

Sustainability in the study was defined as the level of continuation of activities after the end of international funding. Measuring the continuation of activities involved checking whether each eye care activity continued (i.e. out-patient consultation, cataract surgery, outreach, school health, and statistics) or was interrupted after the end of Swiss Red Cross funding the 11 district hospitals where the programme was implemented.

RESULTS

The results showed a relationship between the level of sustainability and the attributes of every activity. The activities with the lowest score for the attributes were less sustained. School health screening was the least sustained activity after the end of international funding. This activity also held the smallest score in terms of attributes: they were the most incompatible and most complex activities, as well as the least triable and observable activities, amongst the four district activities. In contrast, compared to the three other district activities, facility-based consultations were more likely to be routinised because they were perceived by the hospital managers as very compatible, and not complex.

CONCLUSIONS

Using diffusion of innovations theories can help predict the sustainability of specific activities within a health programme. The study also highlighted the need for disentangling the various components of a health programme in order to identify which activities are more likely to be continued within a health system. The same methodology could be used in a different setting and could help predict which innovations are more likely to be adopted and maintained over time.
