Youth knowledge of unhealthy lifestyle choices and obesity vary by gender and behavior

Background: Obesity continues to rise in youth and is associated with increased morbidities. Although studies have focused on parental knowledge and attitudes of obesity, little is known regarding youth understanding of unhealthy lifestyle choices and resultant outcomes. Objective: To determine factors affecting youth knowledge regarding unhealthy lifestyle choices and obesity in 2 zip codes. Design/Methods: Surveys were collected (6/06-10/06) from 437 youth (mean + SD=15.5+2.2 yrs) in Mt. Vernon and Peekskill, NY. Chi square analysis was used. Results: Females (F) more than males (M) overestimated the prevalence of overweight among youth (63% vs. 37%, p=0.015). However, females better understood the role genetics play in overweight (67%F vs. 33%M, p=0.014) and diabetes (64%F vs. 36%M, p=0.005). Of those who did not realize the connection between overweight and diabetes, 87% were Black vs. 13% Non-Black (p=0.047). Poorer nutritional behaviors were associated with incorrect knowledge about the prevalence of overweight (p=0.001) and the link between TV-watching and overweight risk (p= 0.002). Surprisingly, correct knowledge about the link between TV-watching and overweight risk was higher among frequent TV-watchers (p=0.045), but lower among frequent video game players (p=0.009). Higher parental education was positively associated with correct knowledge about: TV-watching and overweight risk (p=0.013), the role genetics play in diabetes (p= 0.002) and the link between maternal diabetes and neonatal outcome (p=0.043). Conclusions: Youth knowledge regarding obesity and resultant outcomes are significantly affected by demographic and behavioral factors. This research will be used to develop targeted public health initiatives in these two communities.
