Those with low income, especially women of African American and Hispanic heritage have the greatest risk of inactivity and obesity. A 4-session (Internet and video) intervention with healthy snack and gym labs was tested in 2 (gym lab in 1) urban low-middle-income middle schools to improve low fat diet and moderate and vigorous physical activity.1 The gym lab was particularly beneficial (p =.002). Fat in diet decreased with each Internet session in which students participated. Percentage of fat in food was reduced significantly p =.018 for Black, White, and Black/Native American girls in the intervention group. Interventions delivered through Internet and video may enable reduction of health disparities in students by encouraging those most at risk to consume 30% or less calories from fat and to engage in moderate and vigorous physical activity.

Surveys conducted in two midwestern cities investigated the hypothesis that says people will perceive effects of mass media as being greater on others than on themselves. Findings demonstrate this, with almost 90% of respondents judging they were less influenced than were others. Respondents with more education saw others as being even more influenced, but not themselves so much. Older respondents were most likely to feel mass media influenced them less than others, perhaps because older people feel they have other sources of information.

Noncontact rate (NCR) for an electronic telephone survey using a random phone number list is similar to other telephone surveys using a random phone list. Refusals appear to be more an effect of the telephone survey than the mode of conducting it. Break-offs could be reduced if more response time were allowed for each question. Findings suggest that the rejection of a computer-administered telehone survey has an effect on the refusal rate because it is easier for people to hang up on a machine than another human. Further research is needed to determine whether the population that refuses to interact with an electronic telephone survey device is significantly different from the population willing to interact with an electronic survey device or human interviewer.
