Comparative Study
Overweight and obesity in native-American adolescents: comparing nonreservation youths with African-American and Caucasian peers.
Previous studies have consistently shown that, compared to national standards, Native Americans across all age groups are disproportionately overweight or obese. Although most available data on rates of obesity in this group come from studies conducted on reservations, the proportion of Native Americans residing on reservation lands is rapidly declining. This study examines the prevalence of overweight and obesity in a population of Midwestern adolescents in public school settings and contrasts Caucasian and African-American adolescents with Native-American youths of the same age. ⋯ Age-specific BMI means for Native-American and Caucasian girls fell largely below the NHANES II reference data. We present several explanations for these results. Given the study limitations, further objective study of the weight status of Native-American children and adolescents in direct comparison with other ethnic groups is recommended.

This study uses quantitative and qualitative information to examine the relationships between predisposing, reinforcing, and enabling factors from a health education planning model and levels of mammography screening, clinical breast exam (CBE), and breast self-exam (BSE) among African-American women. We analyzed data from a random sample household survey of African-American women in a Florida community (n = 281) and three age-homogenous focus groups from the same population. Two thirds of the random sample and all of the focus group participants had less than a high school education and household incomes below $10,000. ⋯ In addition, knowing mammography and BSE guidelines and having been taught BSE in a physician's office were significant predictors of breast-screening behavior for both low- and moderate-income women. Focus-group participants unanimously reported a willingness to listen to physician instructions regarding breast screening and to receive a mammogram if their physician recommended one. Both survey and focus group results emphasize the particular importance of physicians in promoting breast screening among African-American women regardless of their income.
