However, obesity may impact the reliability of age estimations based on pelvic joints. Over the past several decades, the prevalence of obesity has dramatically increased in the United States (US). Since the rate of progression through age\u2010related stages of weight\u2010bearing joints may be influenced by excessive body mass, it is important that anthropologists understand how obesity affects age\u2010related morphological changes in the skeleton. This study investigates the effects of obesity on the validity of the estimated age\u2010at\u2010death based on the Buckberry\u2013Chamberlin and Suchey\u2013Brooks methods by comparing US adults considered normal BMI (BMI 18.5\u201324.9) and obese (BMI\u2009\u2265\u200930). The obese group exhibits overall greater bias (overestimation of age) and inaccuracy, less precision, and lower correlations between estimated and known age than the normal BMI group using both methods, although differences in the pubic symphysis are not statistically significant. For the auricular surface the age of transition from one phase to the next is lower and the standard deviations are greater for the obese as compared to normal weight individuals. This study helps to elucidate how obesity affects the rate of age\u2010related skeletal change of the human pelvis, and shows that the pubic symphysis may be a more reliable indicator of age in obese individuals and that greater standard deviations are needed for obese individuals when estimating age\u2010at\u2010death from the pelvis.
