Background: Researchers in numerous disciplines have investigated the effects of the school environment on childhood obesity (CHO), one of the greatest current health concerns in the United States. There is a gap in current empirical evidence, however, on school personnel's perspectives of this issue. This study examined school personnel's perceptions of obesity as a problem among school-aged children and their views on factors contributing to obesity. Methods: Thirty-one semistructured interviews were conducted with elementary school personnel (teachers, administrators, and support staff) from 5 rural schools with a predominantly Hispanic (58.18%) and Black (30.24%) student population. The constant comparison method was used to identify emergent themes. Results: All but one participant considered obesity to be a problem among elementary children. Factors facilitating obesity most frequently cited by school personnel were home environment, poor nutrition, child control of dietary choices, child inactivity, and entertainment electronics. Conclusions: Child control of dietary choices in both home and school environments was identified as a major contributor to obesity. Further exploration of this control is warranted to understand the complexity of this dynamic and its potential link to CHO.
