This study evaluated a 4-week program to increase the time families spent engaging in outdoor activity. Parents were provided strategies to increase family outdoor activity and locations to be active. Sixteen families completed the program. Duration and number of family outdoor activity bouts per week, type of activities, locations, and family member attendance were measured using logs. Pre/post surveys were conducted to determine the usefulness of providing educational resources and maps. Compared to baseline (216.1±127.3 min/week), family outdoor activity for weeks 1 (316.1±180.2 min/week), 2 (351.1±209.1 min/week), and 4 (317.5±186.8 min/week) were significantly greater at follow-up. At follow-up, parents reported increased regular exercise and encouragement for their child to be active. Children reported adults engaged in physical activity with them and increased transportation to places to be active. This novel program increased family outdoor activity levels and contributes to limited research on strategies to increase outdoor activity in youth.

Background: The use of mobile phones for physical activity (PA) promotion and assessment represents an attractive research area because this technology is characterized by a widespread reach and dynamic features. Purpose: The purpose of this study was to conduct a systematic review of mobile phone-based approaches for encouraging and assessing PA. Methods: Eligible studies were identified through a search of PubMed and PsycINFO and required to address the usability of mobile phones for PA promotion and/or measurement, be written in English, and be published in a peer-reviewed journal between 2010 and 2013. Results: Fifty-two studies were included in this review. The use of mobile phones for PA promotion, assessment, and both promotion and assessment were addressed by 27, 19, and 6 studies, respectively. Out of 26 studies that reported a PA behavior change outcome, 13 observed favorable PA changes, 3 found mixed results, and 10 found no improvements. Ten studies examined the validity of mobile phones for PA assessment and 9 reported favorable outcomes. Participants found mobile phones to be highly acceptable. Discussion: The findings suggest that mobile phones have great potential as a PA promotion and assessment tool among a variety of individuals. Translation to Health Education Practice: Mobile phones may provide practitioners with efficient ways to promote PA and valid ways to assess PA.

Compared eating behaviors and alcohol drinking habits between female varsity college athletes and female controls (non-athletes). Data from a student survey indicated that self-reported problem drinking and eating behaviors existed in both groups at similar rates. There did not appear to be a significant relationship between self-reported alcohol use and eating disorders. (SM)

Res. 20(1):95-102. 2006. The purpose of the study was to evaluate the validity of an air-displacement plethysmography systeta (AP) within the general population, while wearing (1) a racing-type swimsuit ([AP.sub.ss]) and (2) participant's personal undergarments ([AP.sub.UG]), against hydrodensitometry (HW). Fifty women and 50 men were measured for body volume, density, and fat percentage by HW and compared with [AP.sub.ss] and [AP.sub.UG]. For women, [AP.sub.UG] and [AP.sub.ss] were similar, although significant differences (p < 0.001) were observed between [AP.sub.UG] and HW and between [AP.sub.ss] and HW. For men, there was no significant difference between [AP.sub.UG] and HW; however, significant differences (P [less than or equal to] 0.01) were found between [AP.sub.UG] and [AP.sub.ss] and between [AP.sub.ss] and HW. The small discrepancy in measured values between AP and HW are within the measurement error for the instrumentation and these data support the use of AP for determination of body composition in adults across a wide range of body size (body mass index [BMI] 17.7-35.2 kg.[m.sup.-2]) and age (18-57 y). Participants' personal undergarments provide a practical alternative to a spandex swimsuit when measuring body composition by AP in women but not in men.
