Black and white adolescents' perceptions of their weight were examined in this study. A 22-item questionnaire on weight perceptions and weight control was administered to 341 adolescents from two inner city schools in the midwest (138 black and 193 white students). Students were classified as thin, normal, or heavy based on National Health Survey data on height and weight measurements for youth ages 12-17. Significant differences (p less than .05) occurred in how the heavy black and white males and females perceived their weight in comparison to actual weight. All heavy white females perceived they were heavy, in comparison to only 40% of heavy black females; 78% of heavy white males labeled themselves heavy vs. 36% of heavy black males. Thin black and white females were dieting and exercising to lose weight and thin white males were exercising to lose weight. Black males were significantly more likely to believe emotions did not affect their weight when compared to white males. Black females believed exercise levels accounted for their weight, while white females attributed their weight to eating habits. Beliefs about exercise and eating contributed 23% to the variance found in perceived weight status of black males. White males believed access to food and their emotions accounted for their perceived weight. Leading sources of weight control information regardless of ethnicity were television, family members, friends and magazines for females; males used TV, family members, and athletic coaches.

Evidence-based interventions (EBIs) are used in public health to prevent HIV infection among youth and other groups. EBIs include core elements, features that are thought to be responsible for the efficacy of interventions. The authors evaluate experiences of organizations that adopted an HIV-prevention EBI, Focus on Kids (FOK), and their fidelity to the intervention's eight core elements. A cross-sectional telephone survey was administered to 34 staff members from organizations that had previously implemented FOK. Questions assessed how the organization adhered to, adapted, dropped, or altered the intervention. None of the organizations implemented all eight core elements. This study underscores the importance for HIV intervention researchers to clearly identify and describe core elements. More effort is needed to reflect the constraints practitioners face in nonresearch settings. To ensure intervention effectiveness, additional research and technical assistance are needed to help organizations implement HIV prevention EBIs with fidelity.

Background Adult women living in rural areas have high rates of obesity. Although rural populations have been deemed hard to reach, Internet-based programming is becoming a viable strategy as rural Internet access increases. However, when people are able to get online, they may not find information designed for them and their needs, especially harder to reach populations. This results in a “content gap” for many users.Objective User-centered design is a methodology that can be used to create appropriate online materials. This research was conducted to apply a user-centered approach to the design and development of a health promotion website for low-income mothers living in rural Maryland.Methods Three iterative rounds of concept testing were conducted to (1) identify the name and content needs of the site and assess concerns about registering on a health-related website; (2) determine the tone and look of the website and confirm content and functionality; and (3) determine usability and acceptability. The first two rounds involved focus group and small group discussions, and the third round involved usability testing with individual women as they used the prototype system.Results The formative research revealed that women with limited incomes were enthusiastic about a website providing nutrition and physical activity information targeted to their incomes and tailored to their personal goals and needs. Other priority content areas identified were budgeting, local resources and information, and content that could be used with their children. Women were able to use the prototype system effectively.Conclusions This research demonstrated that user-centered design strategies can help close the “content gap” for at-risk audiences.

The present study examined adolescents' actual and perceived weights in relation to why adolescents think they weigh what they do, where adolescents obtain weight control information, and adolescents' weight locus of control. The study was conducted in a Midwestern high school, based on information obtaind from 194 freshmen. Thirty percent of the adolescents perceived their weight category inaccurately when compared to their actual weight and height. One-third of those who were thin, one-half of those who were normal weight, and two-thirds of those who were heavy had been exercising during the past six months to control or lose weight. Six percent of the thin, 41% of the normal weight, and 56% of the heavy students had dieted within the past six months to control or lose weight. The leading sources of weight control information were television, family, friends, and magazines. Teachers were identified as sources of information by less than 10% of the students. Mother, family, and friends were identified as those most helpful in adolescents' attempts to lose weight. Significant chi-square differences were found between weight locus of control orientations and actual and perceived weight categories. Finally, a multivariate analysis of variance was used to analyze adolescents' perceptions of weighing what they do. Eat too much vs too little and exercise too much vs too little were the two reasons identified that were statistically significant. The information obtained from this study may be useful in designing and implementing weight control and nutritional programs for adolescents. For many of the adolescents, their perceptions were different from reality.
