These data suggest that African American and white men in North Carolina receive comparable treatment for prostate carcinoma. Therefore, efforts to reduce the racial disparity in mortality should be directed toward lessening the high incidence of later stage disease at diagnosis and exploring potential biologic differences that may increase the risk of more aggressive disease among African Americans.

Adequacy of VIA declined with age. However, the squamocolumnar junction was visible to the naked eye in the majority of women, indicating that they are good candidates for VIA.

For most women, community-based self-sampling was an acceptable way to participate in a cervical cancer screening program. In low-resource countries, incorporating community-based self-sampling into screening programs might improve coverage of high-risk women.

Body-composition prediction equations were developed using data from a sample of 201 female and male Guatemalan ladinos (ie, people of Amerindian-European descent) aged 11-25 y. Fat-free mass (FFM) values were estimated from body density by using the two-component model and age- and sex-specific values for the density of FFM. The root-mean-square error (RMSE) of the best model predicting FFM from a set of simple anthropometric variables was 1.59 kg for females and 1.90 kg for males. The addition of more extensive anthropometry to the set of candidate predictors reduced the RMSE to 1.42 kg for females and 1.88 kg for males. The subsequent addition of a bioelectrical impedance measure (Ht2/R) further reduced the RMSE to 1.32 kg for females and 1.82 kg for males. These results suggest that for a marginally undernourished population with relatively little body fat, simple anthropometrics are as useful as more sophisticated measures for the prediction of body composition.
