About this study

Official title: Reduction of Inequalities in Overweight and Obesity Management Care Access Among High School Adolescents

Background: The prevalence of overweight and obesity continues to increase in socially less advantaged populations but is stabilizing even is decreasing in socially more advantaged populations. The PRALIMAP trial highlighted the effectiveness of structured screening and care management in decreasing the prevalence of overweight and obesity in high school adolescents over 2 years. The PRALIMAP-INES trial aims to investigate whether a strengthened care management (CM) for socially less advantaged adolescents in school in the short and long term has an equivalent effect as a standard-CM on decreasing the prevalence of overweight and obesity among socially advantaged adolescents.

Intervention: PRALIMAP-INÉS is a mixed prospective and multicenter trial of 1,250 overweight and obese adolescents aged 13 to 18 years who are attending grade 9 and 10 in the 35 state-run schools of the Vosges department (northeastern France) for the academic years 2012-2013 2013-2014 and 2014-2015. Overweight adolescents (including obese) classified as advantaged are allocated to the standard-CM and those less advantaged are randomized to standard CM or strengthened-CM. The standard-CM consists of 5 collective sessions of 2 hr each performed in high school and supervised by a healthcare mobile team specialised in overweight and obesity care management for adolescents. The strengthened-CM consists of 5 collective sessions with the same standard operating procedure as the standard-CM with supplementary interventions between each session: strengthened solicitation with the adolescent and the family, peer-led educational sessions, motivational interviews, financial support for physical activity practice, cooking classes and multidisciplinary consultation meetings. Data on sociodemographics, anthropometrics, physical activity and mental health are collected at 3 visits: at the entry to grade 9 or 10 (before the intervention=T0), at the end of grade 9 or 10 (at the end of the intervention=T1) and at the end of grade 11 (1 year after the intervention=T2). Process evaluation data are also collected during the trial.

Expected results: To confirm the effectiveness of overweight CM for adolescents in a school setting and to highlight or not the effectiveness of specific strengthened interventions adapted for socially less advantaged adolescents to maintain social equality in access to overweight care.

Read the detailed description

Background: The prevalence of overweight and obesity continues to increase in socially less advantaged populations but is stabilizing even is decreasing in socially more advantaged populations. The PRALIMAP trial confirmed major social inequalities in overweight and obesity frequency in adolescents in grade 10. The trial highlighted the effectiveness of structured screening and care management in decreasing the prevalence of overweight and obesity in high school adolescents over 2 years. The PRALIMAP-INES trial aims to investigate whether a strengthened care management strategy for socially less advantaged adolescents in school in the short and long term (just after the intervention and 1 year later) has an equivalent effect as a standard-care management strategy on decreasing the prevalence of overweight and obesity among socially advantaged adolescents.

Hypothesis: A strengthened overweight and obesity care management strategy for overweight and obesity (risk factors of cancer) can improve care access for socially less advantaged adolescents and maintain social equality in terms of overweight and obesity prevalence.

Intervention: PRALIMAP-INÉS is a mixed prospective and multicenter trial (one randomised part and one non-randomised part) of 1,250 overweight and obese adolescents aged 13 to 18 years who are attending grade 9 and 10 in the 35 state-run schools of the Vosges department (northeastern France) for the academic years 2012-2013, 2013-2014 and 2014-2015. After a session to detect overweight and obese adolescents, the social status of included adolescents as "advantaged" or "less advantaged" is determined. Adolescents classified as advantaged are allocated to the standard-care management and those less advantaged are randomized to standard-care management or strengthened-care management. The standard-care management consists of 5 collective sessions of 2 hr each performed in high school and supervised by a healthcare mobile team specialised in overweight and obesity care management for adolescents. The team consists of physicians, dietitians, psychologists and sports educators from the AVRS Association. The content of sessions was validated in the PRALIMAP trial. The strengthened-care management consists of 5 collective sessions with the same standard operating procedure as the standard-care management with supplementary interventions between each session: strengthened solicitation with the adolescent and the family, peer-led educational sessions, motivational interviews, financial support for physical activity practice, cooking classes and multidisciplinary consultation meetings (adjusting the care management according to the social status). Data on sociodemographics, anthropometrics, physical activity and mental health are collected at 3 visits: at the entry to grade 9 or 10 (before the intervention = T0), at the end of grade 9 or 10 (at the end of the intervention = T1) and at the end of grade 10 or 11 (1 year after the intervention = T2). T1 measurement allows for evaluating the short-term effect of the intervention and T2, the long-term effect of a 1-year break from the intervention. Data on participation and from questionnaires, as well as focus group and activity reports, necessary for evaluation, are collected during the trial.

Expected results: With this trial, the investigators expect to confirm the effectiveness of overweight and obesity care management for adolescents in a school setting and to highlight or not the effectiveness of specific strengthened interventions adapted for socially less advantaged adolescents to maintain social equality in access to overweight and obesity care.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Standard care managementBehavioural

    The standard-care management program consists of 5 collective sessions of 2 hr each about nutritional practices (food and physical activity) and on changes of nutritional behaviours. The sessions are organized in high schools by the healthcare team in collaboration with pediatricians, dietitians and the Sickness Insurance Primary Fund.

  • The strengthened care managementBehavioural

    The strengthened care management is the addition of the standard care management and of additional interventions.

    The standard-care management program consists of 5 collective sessions of 2 hr each about nutritional practices (food and physical activity) and on changes of nutritional behaviours. The sessions are organized in high schools by the healthcare team in collaboration with pediatricians, dietitians and the Sickness Insurance Primary Fund.

    The additional interventions are strengthened solicitation and accompaniment, peer-led education, motivational interview, financial support for physical activity practice, cooking classes and meetings of multidisciplinary consultation.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Body Mass Index from to baseline to 1 and 2 years

    Measured: 0-1-2 years

  2. Change in overweight and obesity status according to IOTF norms

    overweight and obesity status is calculated from BMI at each measurement time according to the IOTF norms for age and sex

    Measured: up to 2 years

  3. Change in BMI Z score from baseline to one and two years

    BMI Z score is calculated from BMI at each time measurement using WHO reference and SAS macro

    Measured: up to 2 years

Secondary outcomes (3)

    waist circumference is measured two times at each measurement point by trained nurses and validated by a practitioner

    Measured: 2 years

  2. change in eating attitude score from baseline to 1 and 2 years

    Eating attitudes are measured at each measurement point using then EAT40 questionnaire

    Measured: up to 2 years

  3. Change in anxiety and depression scores from baseline to 1 and 2 years

    HAD questionnaire is used to measure score at each follow-up point
