Objectives To evaluate dose-response associations between misperceived weight and 32 health risk behaviors in a nationally representative sample of US adolescents. Methods Participants included 13,864 US high school students in the 2011 Youth Risk Behavior Survey. Comparing the degree of agreement between perceived and reported actual weight, weight misperception was determined as 5 categories. Multivariable-adjusted logistic regression analyses evaluated associations of weight misperception with 32 health risk behaviors. Results Both underestimated and overestimated weight were statistically significantly associated with all 32 health risk behaviors in a dose-response manner after adjustment for age, sex and race/ethnicity, where greater weight misperception was associated with higher engagement in health risk behaviors. Conclusions Understanding potential impacts of weight misperception on health risk behaviors could improve interventions that encourage healthy weight perception and attainment for adolescents.

estimates, where fECG generated a higher proportion of interpretable minutes of FHR tracing compared to SEM at BMI 25 (Figure 2). CONCLUSION: fECG consistently generated more interpretable 10 and 1-minute FHR tracing segments compared to SEM in women with BMI > 31 and > 25, respectively. Obese women with BMI > 31 may benefit from use of the fECG device in labor.
