Primary Institution: University of Mississippi Medical Center
Hypothesis
The study aimed to assess the scope, socioeconomic and geographic characteristics, and temporal trends of the obesity epidemic in Mississippi.
Conclusion
The 2009 obesity prevalence in all Mississippi counties was substantially higher than the national average and differed by geography and race.
Supporting Evidence
- Obesity prevalence in Mississippi increased from 19.5% in 1995 to 35.4% in 2009.
- Counties with higher obesity rates were clustered in the Delta region and along the Mississippi River.
- Age, sex, race, education, and employment status were associated with obesity.
Takeaway
This study looked at how many people in Mississippi are obese and found that a lot more people are affected than in other states, especially in certain areas.
Methodology
The study used a small-area estimation method applied to BRFSS data to estimate county-level obesity prevalence and assess associations with socioeconomic factors.
Potential Biases
Self-reporting bias may affect the accuracy of obesity estimates.
Limitations
Self-reported data may underestimate obesity prevalence, and the 95% confidence intervals produced were approximations.
Participant Demographics
The study included noninstitutionalized adults aged 18 years or older in Mississippi, with a focus on age, sex, race, education, and employment status.
