    Body mass index (BMI ; wt in kg/ht2 in m) has been proposed as a simple and valid measure for monitoring fatness.

    Using data from a 25-y longitudinal study of rural Guatemalans, we found that, as children, this population was stunted (mean height-for-age z=-2.6) and had low triceps skinfold thicknesses (10% of reference medians), yet had mean BMIs above US reference medians.

    As young adults, mean BMIs were at the 50th and 20th percentiles for women and men, respectively.

    BMIs between ages I and 5 y were moderately correlated (r=0.2-0.3) with those in young adulthood.

    BMI was correlated with subscapular (r=0.5-0.8) and triceps (r=0.2-0.7) skinfold thicknesses at all ages and with predicted percentage body fat in adolescence (r=0.65) and adulthood (r=0.8).

    Fatness was highly centralized, with ratios of subscapular to triceps skinfold thicknesses at the 50th-90th percentiles of reference medians at all ages.

    BMI was a poor indicator of central fat ; the correlation between BMI and waist-to-hip ratio in 14-17-y-old males was - 0.21).

    In stunted populations in developing countries, BMI alone should be interpreted with caution.

    In stunted children, BMls may be high despite small extremity skinfold thicknesses ; BMI alone may overestimate the prevalence of fatness in these children.

    In adults, measures in addition to BMI may be required to identify centralized adiposity in these populations.
