Historically, the Navajo exhibited a low prevalence of overweight, but a number of small studies over the past few decades indicate that the prevalence is increasing.

Two thirds or more of women in all age groups were overweight.
Nineteen percent of the participants underestimated their weight status (underweight, appropriate, overweight) relative to their BMI category and 17% overestimated their weight status.
Women overestimated their weight status more often than men (P<0.05), and participants age 20-39 overestimated their weight status more often than older participants (P<0.001).
Men and women age 60 and older preferred heavier body shape models as ideals of health more often than younger participants (P<0.001).
