Objective:We examined the feasibility of Dance Dance Revolution (DDR), a dance video game, in participants' homes, to increase physical activity (PA) and to decrease sedentary screen time (SST). Methods and Procedures: Sixty children (7.5 ± 0.5 years) were randomized in a 2:1 ratio to DDR or to wait-list control (10-week delay). DDR use was logged, PA was measured objectively by accelerometry. SST was self-reported at weeks 0 and 10. At week 28, after both groups had access to DDR, accelerometry and SST were repeated. Results: Mean use of DDR was 89 ± 82 (range 0-660 min) min per week (mpw). The DDR group showed increased vigorous PA and a reduction in light PA; the control group showed no increase in moderate and/or vigorous PA (MVPA) although they also had a reduction in light PA. Differences between the groups were not observed. The DDR group also reported a decrease in SST of -1.2 ± 3.7 h per week (hpw) (P < 0.05), whereas the controls reported an increase of +3.0 ± 7.7 hpw (nonsignificant). The difference in SST between the groups was significant, with less SST in the DDR group. Between weeks 10 and 28, numeric reductions in SST were reported in both groups. In the DDR group, SST at week 28 (8.8 ± 6.0 hpw) was lower than baseline (10.5 ± 5.5 hpw; P < 0.03). Discussion: This pilot study suggests that DDR reduces SST and may facilitate slight increases in vigorous PA. Further study is needed to better characterize children and contexts in which DDR may promote a healthy lifestyle.

We conclude that vegans have low baseline omega-3 levels, but not lower than omnivores who also consume very little docosahexaenoic and eicosapentaenoic acids. The vegans responded robustly to a relatively low dose of a vegetarian omega-3 supplement.

In the aftermath of Hurricane Floyd in 1999, a Community Advisory Committee requested assistance from its university partners (University of North Carolina) to address stress and increased risk for intimate partner violence (IPV). Collected from 12 study work sites, baseline data indicated that IPV rates were higher among blue-collar women in eastern North Carolina than national population-based rates suggest. IPV victims reported higher levels of perceived stress, psychological distress, somatic complaints, and post-traumatic stress disorder (PTSD) symptoms than did nonvictimized coworkers. As for the relationship of the flood to IPV, no significant increase in IPV incidence occurred after the flood. Regardless of their flood experience, however, IPV victims consistently reported greater stress, PTSD symptoms, and somatic and psychological problems. Moreover, IPV victims may be at higher risk for stress-mediated chronic illnesses and for using negative coping behaviors. This study uses an established trusting relationship between researchers and community members to explore community needs and inform intervention design.
