Obesity, hypertension, and migration: a meta-analysis of populations of the South Asian diaspora.

The effects of migration on human health have been a topic of interest for demographers and human biologists. Even if migrants to a new region achieve a higher standard of living in their new place of residence, their improved living conditions may not be associated with better health. Part of the difficulty of understanding the health consequences of migration is the complications in trying to control for variables that may affect health, such as gender, age, and urban or rural environment of migrants and nonmigrants.

Indentured migration and differential gender gene flow: the origin and evolution of the East-Indian community of Limón, Costa Rica.

After the emancipation of African slaves in the Caribbean, the labor void left by out-migrating former slaves was filled by in-migrating indentured servants from prepartition India and China. In some areas of the Caribbean such as Trinidad, Suriname, and Guyana, the East-Indian migrants formed large communities. In this article, we report a study based on mtDNA and Y-chromosomal markers of a small East-Indian community from Limón, Costa Rica.
