Moms and teens team up to fight obesity in black girls

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria for daughters are: * English speaking; * Black; * grade 9 or 10; * daily access to the internet outside of school and/or work through an iOS or android smart phone, tablet, or personal computer; * either high-normal weight (between ≥50th and \<85th percentile for age and gender) or overweight (between ≥85th and \<95th percentile for age and gender) as the purpose of this study is weight maintenance and obesity prevention in at-risk daughters rather than obesity treatment; 98 and * have either a poor diet, (defined as consuming \<1 vegetable or \<1 fruit per day) 99 or inadequate PA (defined as \< 60 minutes per day, 7 days per week). 99,100 Inclusion criteria for mothers are: * English-speaking; * Black; * co-residing biological mother or mother-figure and legal guardian of the participating daughter; * the person primarily responsible for meals in the household; and * access to the internet through an iOS or android smart phone, tablet or personal computer. In a longitudinal study of 480 adults, 84% of adults with obesity were adolescents with high normal weight status (≥50th and \<85th percentile). National data on cell phone ownership show that 81% of Black students and 68% of Black parents own a smart phone Exclusion Criteria: The exclusion criteria for both daughters and mothers includes: * having conditions/procedures that prevent the oral consumption of foods (e.g., gastric feeding tubes); * presence of physical limitations that would preclude participation in the PA activity components of the intervention; * altered dietary intake (e.g., pregnancy, eating or metabolic disorders except for type 1 or type 2 diabetes); and * at baseline physical assessment, participants screened for uncontrolled blood pressure (systolic \> 130, diastolic \>80 for daughters; and systolic \>160, diastolic \>100 for mothers) will be eligible only with a healthcare provider release. * participants with diagnosed type 1 or 2 diabetes will be eligible for participation only with a healthcare provider release. * mothers will be screened for cardiovascular disease and musculoskeletal risk factors with the 7-item Physical Activity Readiness Questionnaire. Mothers that answer 'yes' to any item on the Physical Activity Readiness Questionnaire will be eligible only with a healthcare provider release. Daughters or mothers who are asked to provide healthcare provider release will be referred to the Chicago Department of Public Health if they do not have a primary care provider. To be eligible to participate in either condition, both the daughter and her mother must be willing and eligible to participate in the study.
