RESUMEN
OBJECTIVE: Urban minority girls are at risk for summertime weight gain, and may also experience insufficient summertime sleep. Few studies have objectively measured sleep in this population or examined correlates, including physical activity (PA). This study is the first to objectively describe summertime sleep among urban minority girls. METHODS: Data were collected at a community-based summer program that promoted PA (n = 60 girls, ages 10-14 years), at two time points: before beginning programming (T1; unstructured context) and during the final week of programming (T2; structured context). RESULTS: At both time points, participants experienced shorter nighttime sleep than the recommended amount for girls their age. African American girls recorded significantly less sleep than Latina girls in the unstructured context. Findings also suggest that sleep schedules have an influential role in youths' abilities to obtain adequate sleep. CONCLUSION: Overall, summertime sleep is an understudied health behavior that may be important to consider among minority youth.

Low-income minority females are disproportionately affected by obesity. The relevance of summer months to weight gain is often overlooked. Some evidence suggests that summer programming, such as day camps, may offer increased opportunities for structured physical activities resulting in less weight gain. This study examined the effectiveness of Girls in the Game, a six-hour four-week sports and fitness summer camp program, in increasing physical activity (PA) and reducing body mass index and media use. Statistically significant increases were observed in four physical activity measures including total PA, MVPA, average number of ten-minute bouts of MVPA, and minutes participants spent in bouts of at least ten minutes of MVPA. This chapter highlights the importance of investigating the potential relationships among weight, physical activity, sedentary time, media use, and participation in summer camp programming.

Summertime has emerged as a high-risk period for weight gain among low-income minority youth who often experience a lack of resources when not attending school. Structured programming may be an effective means of reducing risk for obesity by improving obesogenic behaviors among these youth. The current multi-method study examined sedentary time, physical activity, and dietary intake among low-income urban minority girls in two contexts: an unstructured summertime setting and in the context of a structured 4-week community-based summer day camp program promoting physical activity. Data were analyzed using paired-sample t tests and repeated-measure analyses of variance with significance at the p < .05 level. Results evidenced no significant differences in total calories and fat consumed between the unstructured and structured settings. Participants exhibited significant increases in fruit consumption and physical activity and significant decreases in sedentary time of over 2 h/day and dairy consumption when engaged in structured summer programming. All improvements were independent of weight status and age, and African-American participants evidenced greater changes in physical activity during programming. The study concludes that structured, community-based summertime programming may be associated with fewer obesogenic behaviors in low-income urban youth and may be a powerful tool to address disparities in weight gain and obesity among high-risk samples.
