Military Rank And Obesity: A Cross-Sectional Study of Military Dependents Cared for at MAMC
ObjectiveThis study examines BMI data of military spouses based on the rank of their sponsor.
Background• BMI is routinely measured at all clinic encounters to screen for obesity. • Demographics of obesity in military dependents is unknown• USPSTF recommends referral of all adults with a BMI 30 or higher to intensive, multi-component, behavioral interventions
Results• Female spouses of enlisted soldiers have
statistically higher mean BMI in all age groups• No difference in mean BMI of male spouses
however averages were near a BMI of 30 and more data needed
• BMI generally increases with age in both enlisted and officer female spouse
CPT James H Winegarner, MD. Madigan Army Medical Center Department of Family Medicine, Fort Lewis, WA
BMI is consistently higher in female spouses of enlisted soldiers compared to similar aged officer spouses. Male spouse BMI data underpowered to show difference. This data can be used to target interventions to address obesity.
Conclusion
Discussion• Female enlisted spouses are, on average, 2.6-
4.8 BMI points heavier than their age matched officer counterparts. • BMI difference unlikely due to access to health
care or exercise facilities, and possibly food costs as military benefits partially control for these variables• Possible confounders: Size of families, normal
BMI patients less likely to see physicians, number of deployments and low number of male visits • Main socioeconomic status difference between
groups: income and education in household
