Brief summary

A randomized control trial to compare the efficacy of two distinct parent treatments on weight loss maintenance for adolescents with obesity participating in a lifestyle intervention including nutrition education, exercise and behavioral support. Funding support from NIH via 1R01HD095910

Detailed description

Investigators will recruit adolescents with overweight or obesity (BMI\>85th percentile) and a parent (BMI \> 25 kg/m2). Families will participate in one of two 4-month treatments: 1) TEENS+ Parents as Coaches (PAC), engaging parents as helpers in their child's weight management, or 2) TEENS+ Parent Weight Loss (PWL), engaging parents in their own weight management. All adolescents will participate in TEENS+, which includes behavioral support, nutrition education, and supervised physical activity. For adolescents, the intervention will consist of weekly behavioral weight management group sessions and weekly 1 hour exercise sessions. Each adolescent also has a monthly individual session with a behavior coach. Parent groups meet weekly for 1 hour according to treatment arm (PAC or PWL). All PWL sessions are separate from their adolescent. Bi-weekly sessions in the PAC arm are combined with parents and adolescent. Assessments will consist of anthropometric measures, psychological surveys and dietary and PA evaluations. Assessments will be completed at baseline, 2 months, 4 months (post-test), 8 months and 1 year.

Body Mass Index (BMI) Change4 months to 12 month [follow up phase]Body Mass Index (BMI) change (kg/m2; adolescent) during the maintenance phase (4-month to 12-month).
Body Mass IndexBaseline, 2-, 4-, 8-, and 12-monthsNational Health and Nutrition Examination Survey (NHANES) Anthropometry methods were used to measure height and weight to calculate Body Mass Index (BMI). At 0, 2, 4, 8, 12 months, trained staff measured adolescent height and weight (in light clothing and after a 12 hour fast) to the nearest 0.1cm and 0.1kg using a precision stadiometer and digital scale, respectively.

Secondary

MeasureTime frameDescription
Role ModelingBaseline, 2-, 4-, 8-, and 12-monthsAt 0, 2, 4, 8, 12 months, adolescents will complete the Family Experiences Related to Food Questionnaire (FERFQ) is an 8 or 9-item measure (father and mother version, respectively) that will assess family commentary about weight and shape as well as family modeling of diet and weight concerns. Scores range from 1-5 with higher scores indicating more negative role modeling of dietary behaviors. Results reflect the adolescent's perception on their parent (mom or dad) participating in the study.
Adolescent Reported Demandingness Parenting StyleBaseline, 2-, 4-, 8-, and 12-monthsThe Authoritative Parenting Index (API) was used to assess adolescent-report of demandingness parenting style and will be administered at 0, 2, 4, 8, 12 months. Scores range from 7-28 with higher scores indicating greater perceived demandingness from the parent. Results reflect the adolescent's perception on their parent (mom or dad) participating in the study.
Adolescent Reported Authoritative Parenting StyleBaseline, 2-, 4-, 8-, and 12-monthsThe Authoritative Parenting Index (API) was used to assess adolescent-report of authoritative parenting style and was administered at 0, 2, 4, 8, 12 months. Scores range from 16-64 with higher scores indicating the adolescent perceives their parent to have a higher level of authoritative parenting behavior. Results reflect the adolescent's perception on their parent (mom or dad) participating in the study.
Home Exercise EnvironmentBaseline, 4-, 8-, and 12-monthsThe Exercise Environment Questionnaire (EEQ) assessed the availability of types exercise equipment in the home. Measures will be completed at 0, 4, 8, 12 months. Scores are calculated by summing responses. Scores range from 0-39 with higher scores indicating more exercise equipment in the home.
Monitoring Child Feeding PracticesBaseline, 2-, 4-, 8-, and 12-monthsParents will complete the Child Feeding Questionnaire (CFQ; Adolescent version) to assess monitoring feeding style. Scores range from 1-5 with higher scores indicating a greater degree of monitoring feeding practices.
Parent WeightBaseline, 2-, 4-, 8-, and 12-monthsTrained staff will measure weight (in light clothing and after a 12 hour fast) to the nearest 0.1kg using digital scale at baseline, 2-, 4-, 8- and 12-months.
Parent Weight Changebaseline to 4 month [intervention phase] and 4 month to 12 month [maintenance phase]Trained staff will measure weight (in light clothing and after a 12 hour fast) to the nearest 0.1kg using digital scale at baseline and 4-months. Weight change will be calculated from these values.
Physical ActivityBaseline, 4-, 8-, and 12-monthsAccelerometers were worn for 1 week by adolescents and parents for each assessment period (0, 4, 8, and 12 months) to assess adolescent and parent physical activity. Results represent total time (minutes/day) spent in moderate/vigorous activity (MVPA). Data reported is based off the average MVPA minutes per day of valid wear days.
Physical Activity Change4-month to 12-monthTo assess adolescent and parent physical activity change during the maintenance physical (post-intervention) phase of the program from 4-months to 12-months. Results represent the change in total time (minutes/day) spent in moderate/vigorous activity (MVPA).
Physical Activity Energy ExpenditureBaseline, 4-, 8-, and 12-monthsAccelerometers will be worn for 1 week by adolescents and parents for each assessment period (0, 4, 8, and 12 months) to assess adolescent and parent physical activity energy expenditure (EE). Results represent the average daily physical activity energy expenditure (kilocalories/day) estimated via accelerometer. Results are based off EE = (Metabolic Equivalent of Task \[MET\] value of activity x body weight kg x \[minutes of activity/60\]) with MET values of 2.5, 4, and 7 utilized for light, moderate, and vigorous activities, respectively.
Physical Activity Energy Expenditure Change4-month to 12-monthTo assess adolescent and parent physical activity energy expenditure change during the maintenance physical (post-intervention) phase of the program from 4-months to 12-months.
