Dementia Attributable Healthcare Utilizations in the Caribbean versus United States.

Background: Despite the high burden of Alzheimer's disease and other dementias among the Hispanic population worldwide, little is known about how dementia affects healthcare utilizations among this population outside of the US, in particular among those in the Caribbean region.

Objective: This study examines healthcare utilization associated with Alzheimer's disease and other dementias among older adults in the Caribbean as compared to the US.

Methods: We conducted harmonized analyses of two population-based surveys, the 10/66 Dementia Group Research data collected in Dominican Republic, Cuba, and Puerto Rico, and the US-based Health and Retirement Study.

Color disparities in cognitive aging among Puerto Ricans on the archipelago.

This research seeks to contribute new understanding of color disparities and gender in cognitive aging among older adults residing in Puerto Rico. We use the island-representative Puerto Rican Elderly Health Conditions (PREHCO) longitudinal study that measures cognitive health at baseline and cognitive decline between waves. In pooled models, we discern little or no color disparities in cognition at baseline.

Apolipoprotein E (APOE) genotype, dementia, and memory performance among Caribbean Hispanic versus US populations.

Introduction: Apolipoprotein E (APOE) is considered the major susceptibility gene for developing Alzheimer's disease. However, the strength of this risk factor is not well established across diverse Hispanic populations.

Methods: We investigated the associations among APOE genotype, dementia prevalence, and memory performance (immediate and delayed recall scores) in Caribbean Hispanics (CH), African Americans (AA), Hispanic Americans (HA) and non-Hispanic White Americans (NHW).

Race/Ethnic Differences, Skin Tone, and Memory Among Older Latinos in the United States.

Objectives: U.S. Latino populations are diverse.

Associations between education and dementia in the Caribbean and the United States: An international comparison.

Introduction: Despite high dementia prevalence in Hispanic populations globally, especially Caribbean Hispanics, no study has comparatively examined the association between education and dementia among Hispanics living in the Caribbean Islands and older adults in the United States.

Methods: We used data on 6107 respondents aged 65 and older in the baseline wave of the population-based and harmonized 10/66 survey from Cuba, the Dominican Republic, and Puerto Rico, collected between 2003 and 2008, and 11,032 respondents aged 65 and older from the U.S.

The Role of Parents and Family Networks in Adolescent Health-Seeking in Ethiopia.

Objective: This study examines the roles of parents, extended kin, and exchange networks in adolescent health-seeking behavior in Ethiopia.

Background: Prior studies highlight the role of mothers in children's health, whereas fathers, extended kin and other network partners remain largely unexamined. The gender intensification hypothesis suggests that adolescents gravitate toward same gender parents for advice and assistance with health-related issues.

Prospects for the Comparative Study of International Migration using quasi-longitudinal micro-data.

Background: Longitudinal micro-level data about international migration behavior are notoriously difficult to collect, but data collection efforts have become more frequent in recent years. Comparative research of the patterns and processes of international migration, however, remains quite rare, especially that which compares across regions.

Objective: We highlight the promises and difficulties of comparative international migration research, by offering a detailed comparison of two prominent data collection efforts.

Migrant networks and international migration: testing weak ties.

This article examines the role of migrant social networks in international migration and extends prior research by testing the strength of tie theory, decomposing networks by sources and resources, and disentangling network effects from complementary explanations. Nearly all previous empirical research has ignored friendship ties and has largely neglected extended-family ties. Using longitudinal data from the Migration between Africa and Europe project collected in Africa (Senegal) and Europe (France, Italy, and Spain), this article tests the robustness of network theory-and in particular, the role of weak ties-on first-time migration between Senegal and Europe.
