BMI indicates body mass index: SE, standard error; GED, general education degree; voc, vocational; tech, technical; assoc, associate's degree; col, college degree; bach, bachelor's degree; master, master's degree; PhD, doctorate degree.
Acceptable waist circumference is ≤102 cm for men and ≤88 cm for women; values above this are considered high.
The p values are χ2 p values for difference in proportion of categorical variable compared with BMI level and waist circumference level. For continuous variable of BMI and waist circumference, the p value is the difference in means across level of BMI and waist by using analysis of covariance.
This p value is for Alaska and Navajo with BMI categories.
This p value is for difference with Alaska region with BMI categories.
