Adolescent girls will attend healthy lifestyle sessions that include nutritional education and physical activity education and build skills in the areas of values clarification, mindfulness, self-regulation skills, acceptance of uncomfortable states, goal-setting, problem solving, and self-monitoring.

This includes 15 sessions that are each 90 minutes in length. Intervention sessions will be weekly for the first 2 months, bi-weekly for the next 2 months, and monthly for the last 2 months.

Number of teens who enrolled and completed both initial baseline visits. The recruitment strategy will be deemed 'feasible' if 15 participants are recruited within the 8 weeks.

The attrition strategy will be deemed "feasible" if there is less than 50% attrition at the end of the 6-month intervention. This percentage details attrition, or the percentage of participants who did not complete the intervention.

Of the participants who completed baseline visits, this percentage details what percentage of enrollees decided to participate in the intervention. The study will be deemed "acceptable" if at least 80% of enrolled participants decide to participate in the intervention.

This percentage details the percentage of those who attended all 15 intervention sessions among intervention completers (n=11). The study will be deemed 'acceptable' if at least 70% of intervention completers attend all sessions.

Body mass index (BMI) z-scores are measures of weight adjusted for the height, age, and sex of the child. BMI z-scores correspond with growth chart percentiles. These scores are calculated with an external reference rather than internal references. In this study, the Centers for Disease Control and Prevention SAS program was used to calculate scores based on 2000 CDC growth charts. Additionally, a clinically significant change in BMI z-score was defined as greater than or equal to -0.15 as this decrease has shown improvements in one or more cardiovascular disease risk factor. The central z-score value is 0, representing the population mean, and standard deviations below the mean indicate better outcomes.

Number of teens who enrolled and completed both initial baseline visits. The recruitment strategy will be deemed 'feasible' if 15 participants are recruited within the 8 weeks.

60 participants were screened for eligibility. 43 were excluded (12 did not meet eligibility criteria; 31 declined to participate). 17 consented and 16 completed initial baseline visits. 13 decided to participate in the intervention. 11 received the allocated intervention and 2 did not (dropped out due to time constraints). Demographic variables were assessed among intervention participants, explaining the discrepancies between the results and participant flow sections.
