The study includes 12 high schools and 19 of their feeder middle schools in the Los Angeles Unified School District and the surrounding communities. Interventions will be implemented among parents, health care providers, and in schools in an integrated fashion with the goal of improving social context factors related to health outcomes among adolescents. The evaluation phase will include in-school surveys with adolescents at all middle schools ## Detailed Description In the current study we plan to implement interventions at four social context levels, that is, with parents, providers or in other medical institutions, schools and community venues, to improve communication between adolescents and adults, facilitate increased access and utilization of health care services, and appropriate supervision of adolescents outside of school hours. As such the goals of the specific level interventions are as follows. Among parents: (1) to enhance communication and relationship satisfaction; (2) increase parents participation in the healthcare of their adolescents; and (3) to enhance appropriate monitoring and supervision of adolescents. Among school-based health care providers: (1) to increase access to and utilization of services by adolescents; and (2) to increase STD screening of adolescents. In middle schools: (1) to increase access and utilization to supervised after-school activities, either at school or in the community; (2) to address quality and fidelity of health education curriculum provision and teacher training; (3) to increase parental participation in school-related activities. In high schools: (1) to increase access and utilization to supervised after-school activities, either at school or in the community; (3) to address quality and fidelity of health education curriculum provision and teacher training; (4) to increase parental participation in school-related activities; (5) to increase awareness and utilization of school-based condom availability programs. In community venues: (1) increase adolescents utilization of community-based clinical services; (2) to increase adolescent utilization of non-clinic-based screening; and (3) to increase utilization of community-based supervised activities for youth. Activities will address these goals with the ultimate purpose of reducing adolescent risk for STDs, including HIV, and teen pregnancy through (1) increased age at first intercourse, (2) return to abstinence among sexually active adolescents, (3) decreased rates of unprotected sex among adolescents, (4) and increased screening and treatment of STD-infected adolescents. ## Eligibility - **Minimum age:** 11 Years - **Maximum age:** 20 Years - **Sex:** ALL - **Healthy Volunteers:** Yes ``` Inclusion Criteria: * Student at participating school Exclusion Criteria: * None ``` ## Interventions - **Project Connect** (BEHAVIORAL) ## Primary Outcomes - **Proportion of students who return to abstinence (measured yearly for 6 years)** - **Proportion of sexually active students who have unprotected intercourse (measured yearly for 6 years)** - **Proportion of sexually active students screened for chlamydia (measured yearly for 6 years)** - **Prevelance of chlamydia from Baseline to Year 6** - **Number of students who are sexually experienced (measured yearly for 6 years** ## Secondary Outcomes - **Parental monitoring (measured yearly for 6 years)** - **Parental communication (measured yearly for 6 years)** - **Supervision (measured yearly for 6 years)** - **Participation in after-school activities (measured yearly for 6 year)** - **Use of reproductive health care services (measured yearly for 6 years)** ## Locations (1) - Health Research Association, Los Angeles, California, United States ## Recent Field Changes (last 30 days) - `eligibility.maxAge` — added _(2026-05-12)_ - `eligibility.sex` — added _(2026-05-12)_ - `status.overallStatus` — added _(2026-05-12)_ - `status.whyStopped` — added _(2026-05-12)_ - `status.primaryCompletionDate` — added _(2026-05-12)_ - `status.completionDate` — added _(2026-05-12)_ - `status.lastUpdatePostDate` — added _(2026-05-12)_ - `design.phases` — added _(2026-05-12)_ - `design.enrollmentCount` — added _(2026-05-12)_ - `eligibility.criteria` — added _(2026-05-12)_ - `eligibility.minAge` — added _(2026-05-12)_ - `outcomes.primary` — added _(2026-05-12)_ - `outcomes.secondary` — added _(2026-05-12)_ - `armsInterventions.interventions` — added _(2026-05-12)_ - `sponsor.lead` — added _(2026-05-12)_ - `sponsor.collaborators` — added _(2026-05-12)_ - `results.hasResults` — added _(2026-05-12)_ - `locations.health research association|los angeles|california|united states` — added _(2026-05-12)_ --- *Canonical: https://parkinsonspathways.com/agent/trials/NCT00146406.md* *Source data (authoritative): https://clinicaltrials.gov/study/NCT00146406* *This page is a raw mirror with no AI summary, no editorial enrichment, and no Parkinson's-specific filtering.*
