Racial/Ethnic Differences in Physical Activity in a Low-Income Sample in Texas.

Introduction: National data reveal that the age-adjusted prevalence of leisure-time physical inactivity is higher among Blacks and Hispanics compared with Whites.

Factors related to poor diet quality in food insecure populations.

It is well-known that consumption of nutrient-rich foods, especially fruits and vegetables, are low among food insecure populations.

In this analysis, we examine these underlying factors across food-secure and food-insecure populations in Texas.
