Commentary: Assessing food insecurity in Trinidad and Tobago

Gulliford and colleagues report in this issue of the International Journal of Epidemiology on a study in Trinidad and Tobago that investigated whether household food insecurity was associated with obesity in this middle-income country. They found that food insecurity was associated with underweight but not with obesity. Food insecurity was also associated with decreased consumption of fruits and vegetables, a result previously reported in several studies, and with physical limitations, a result previously reported for elders in the US.
