SE=standard error; PR=prevalence ratio
Infrequent self-weighers (IFW)=a few times per month or less; Frequent self-weighers (FW)=weekly or a few times per week or more. Bolded odds ratio (95% CI) and p-values indicates significance (p<0.05)
N’s may be different because of missing data among self-reported behaviors.
Poisson regression analyses controlling for age, socio-economic status and race/ethnicity with infrequent self-weighing as reference group.
Mean Difference is the beta coefficient from the linear regression analysis.
Linear regression analyses controlling for age, socio-economic status and race/ethnicity.
