This project will examine the effectiveness of a primary care based intervention to help overweight teen girls adopt healthy lifestyle practices. Participants will be adolescent females from Kaiser Permanente Northwest primary care clinics with a body mass index above the 90th percentile. Teens will be randomly assigned to (1) a behavioral weight control program (enriched intervention), (2) brief primary care counseling (low intensity intervention), or (3) usual-care (control). For both of the project’s active intervention arms, teens’ primary care providers will be given customized plans describing the teen’s eating and physical activity habits and instructions on how to best work with these teens and their families. The behavioral weight control program will be specifically tailored for teen girls and will include separate group meetings for teens and parents, follow-up telephone contacts with their group leader, and coordinated feedback from the teen’s primary care provider.

Overweight / obesity among youth has recently been declared a “public health crisis” in the United States and other Western countries due to its alarming increase in prevalence (Flegal, 1999; Kohn & Booth, 2003; Lobstein et al., 2004; Sokol, 2000). Over the past decade, overweight in youth (Body mass index [BMI] > 95th percentile) has increased 4% for school-age children, 6 – 11 years old. Adolescents, 12 – 19 years of age are even more overweight (5%) (Ogden et al., 2002). Further, American adolescents had the highest prevalence of overweight among 15 western countries included in a cross-sectional, nationally representative school-based study (Lissau et al., 2004). Such trends are particularly troubling given the psychosocial and physical health risks associated with being overweight in childhood (Must & Strauss, 1999). Overweight among youth appears to confer longer-term health risks even among later normative weight adults (Must et al., 1992). Further, both longer-term health risks and the probability of adult obesity is greater for overweight adolescents than for those developing weight problems earlier in childhood (Must et al., 1992; Whitaker et al., 1997). Collectively, these factors suggest adolescent weight control is an important public health priority.
Clinic-based weight control treatments for youth have demonstrated some success, however, most empirically-supported interventions have been designed for younger school-age children and their families (see Epstein et al., 1998 for a review). Even though a large volume of research explores adult-weight control (see NIH-NHLBI, 1998 for a review) and (though more limited) substantial research examines childhood obesity (see Epstein et al., 1998 for a review), obesity treatments for adolescents have not been adequately studied. Furthermore, almost all empirically tested weight control interventions among youth have been based in academic research clinics rather than the primary care medical settings, in which weight problems among these youth are most often identified and, arguably, in which they could be most efficiently treated. Placing adolescent weight-related interventions within primary medical care settings could make such interventions both more cost-effective and easier to disseminate. The purpose of this study is to assess the feasibility, acceptability, relative cost, and efficacy of a collaborative primary care-based behavioral lifestyle intervention (Enriched Intervention – EI) for overweight adolescent females and their families. This multi-component intervention, adapted for gender and developmental stage, will include a combination of assessment, group teen and parent sessions, individual telephone-based coaching contact, and a distinct collaborative care component with follow-up visits to the youth’s primary care provider [PCP]. Further, we will compare the EI to a low intensity intervention [LII] (assessment and information about healthy diet and activity, and follow-up visits with the youth’s PCP) and a usual care control condition.
