简要总结
This study explores how a physical activity program can affect hormone health and diabetes risk in girls ages 8-12 who may be at higher risk. The study aims to address:
- Does the 'ActiveGirls' program meet the needs of girls and families in engaging them to increase physical activity?
- What is the trend of markers of diabetes risk and puberty hormones over a 1-year period and how are these levels related to physical activity levels?
Participants in this study will either:
- Participate in a 'full' intensity intervention that includes educational messages (text/email) as well as health coaching visits to support physical activity over a 6 month period
- Participate in a delayed 'lower intensity' intervention that includes only educational messages (text/email)
- Participants in both groups will complete at-home activity monitoring, two study visits for check-ups and tests, and surveys
详细描述
This study is a pilot randomized trial to assess the preliminary feasibility and efficacy of a physical activity intervention enrolling peripubertal females.
Participants will be assigned to the intensive intervention group with text messaging and health coaching versus delayed lower intensity comparison group with a lower intensity text-only intervention. Participants in both arms will complete objective measures of body composition, insulin dynamics, reproductive hormones, physical activity and fitness over a one-year period. Participants as well as a caregiver proxy will complete survey measures addressing lifestyle behaviors and social-emotional wellness. Given evidence suggesting increased effectiveness of whole-family lifestyle interventions, a parent/caregiver will assist with child participation in the ActiveGirls program, including facilitating health coaching visits and at-home physical activity sessions. assist in intervention delivery and outcomes assessment.
After the baseline visit, there are 2 more study assessment points at 6-months and 12-months. The baseline and 12-month assessments require in-person visits to the MGH Translational and Clinical Research Centers (TCRC); the 6-month assessment is performed remotely. All study visits will occur at MGH.

研究组 & 干预措施
Full Intensity Intervention
Participants in this arm will receive the 'full' intensive ActiveGirls intervention, which will include educational messaging (3-4/week, via email or text message) as well as a series of 6 health coaching visits for physical activity goal setting. Participants in this arm will receive the intervention in months 1-6 of their study participation.
干预措施: ActiveGirls Physical Activity Program (Full) (Behavioral)
Delayed lower intensity comparison group
Participants in this arm will receive a lower intensity educational messaging only intervention in months 7-12 of their study participation. This group will not receive health coaching.
干预措施: ActiveGirls Physical Activity Program (Delayed Lower Intensity) (Behavioral)
结局指标
主要结局
Retention
时间窗: 12 months
Proportion of participants completing each study assessment point/coaching visit divided by total participants enrolled/eligible
Acceptability
时间窗: 12 months
Intervention rating as acceptable by parent-child dyads using validated measure (Acceptability of Intervention Measure (AIM)); The AIM score is reported on a scale of 0-4. 0 is the minimum and 4 is the maximum. Higher scores mean greater intervention acceptability
