Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The "Healthy Habits, Healthy Girls" is a 6-month multi-component school-based intervention developed in reference to Social Cognitive Theory and includes: (1) enhanced physical education classes (2x/week and delivered by a Physical Education teacher), (2) break/lunch-time physical activity sessions (the participating girls will encourage younger girls to make Physical Activity during break and/or lunch-time. This session will only happen after 3 months of enhanced Physical Education classes, so the girls will be able to pass their knowledge for the others), (3) Nutrition and Physical Activity handbooks with 10 health messages (lessons to be done at home and their family); (4) 4 Parent newsletters; (5) Food and Physical Activity diaries for self-monitoring; (6) text-messages using a group application for more interaction and social support; and (7) 10 weekly Nutrition and Physical Activity key messages (delivered by a Nutrition and Dietetics Bachelor degree and/or Physical Education teacher during break). The intervention will be evaluated using a randomised controlled trial in 10 public schools in the city of São Paulo, Brazil (5 control and 5 intervention) and based on the 10 weekly key messages: (1) eat fruit and vegetables daily; (2) Do Physical Activity respecting your limits; (3) Eat a healthy breakfast every day; (4) Do Physical Activity with your family and friends; (5) Control the portion size you eat during meals - and sit while you are eating; (6) Reduce your sitting time during school break, after the school period and on the weekends; (7) Have less "junk food" for meals/snacks and munch less; (8) Identify the excuses for not practicing PA; (9) Drink water and substitute sodas and artificial juices for water, homemade natural fruit juices and coconut water, and; (10)Make family meals.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 19 years (Child, Adult)

Accepts Healthy Volunteers

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: No intervention group
The control group will not receive any intervention during the one year of this study. Only the baseline, 6-12 months assessments (anthropometrics, PA, dietary intake, social cognitive mediators and sedentary behaviors). To prevent compensatory rivalry and resentful demoralization, the control school will be provided with a condensed version of the following 12-month assessments. The condensed version of the program will include the professional learning workshops for intervention schools and the intervention materials (i.e., nutrition and PA handbooks and PA leadership handbook).
Experimental: Healthy habits, healthy girls group
The intervention group will receive a 6-month multicomponent intervention (i.e., enhanced physical education classes; interactive seminars; nutrition workshops; text messages; and parents newsletters) and materials (i.e., nutrition and PA handbooks; cooking books; Choreographies CDs and PA leadership handbook).
Behavioral: Healthy Habits, Healthy Girls Group
The intervention group will receive a 6-month multicomponent intervention (i.e., enhanced physical education classes; interactive seminars; nutrition workshops; text messages; and parents newsletters) and materials (i.e., nutrition and PA handbooks; cooking books; Choreographies CDs and PA leadership handbook).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Body Mass Index
Time Frame: 1 year
Weight will be measured to the nearest 0.1kg without shoes, in light clothes using a portable digital scale and height was recorded to the nearest 0.1cm using a portable stadiometer. BMI was calculated using the standard equation (weight [kg]/height [m2]) and BMI z-score was calculated using the "LMS" method
1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Dietary intake
Time Frame: 1 year
Dietary intake was assessed a 49-item semi-quantitative food-frequency questionnaire (FFQ) Subjects were asked about their consumption over the previous 12-months. The frequency options ranged from "Never" to "at least twice a day" for all the items.
1 year
Physical activity level
Time Frame: 1 year
PA was assessed using a brief PA questionnaire that aims to evaluate the PA frequency and intensity realized in one week. The subjects should inform the number of times of light-to-vigorous intensity PA practiced for at least 30 minutes during a period of seven days (i.e., week and weekends).
1 year
Sedentary behaviors
Time Frame: 1 year
The subjects reported the time spent during the weekdays (Monday through Friday) and weekends (Saturday and Sunday) in the following activities: watching television/videos/DVDs, using the computer for leisure activities (games and social networks), using telephone and studying, reading or doing homework.
1 year
Physical activity social-cognitive mediators
Time Frame: 1 year
Social cognitive scales for dietary and PA behaviors based on constructs from Social Cognitive Theory were adapted and designed for the study. Participants will complete PA scales for the following constructs: self-efficacy, intentions, family and friends support, environment perceptions (situation), behavioral strategies (self-control), outcome expectations (perceived benefits) and outcome expectancies (valued placed on benefits).
1 year
Dietary social cognitive mediators
Time Frame: 1 year
Social cognitive scales for dietary behaviors based on constructs from Social Cognitive Theory were adapted and designed for the study. Participants will complete dietary scales for the following constructs: self-efficacy, intentions, family and friends support, environment perceptions (situation), behavioral strategies (self-control), outcome expectations (perceived benefits) and outcome expectancies (valued placed on benefits)
1 year
Waist circunference
Time Frame: 1 year
waist circumference will be measured to the nearest 0.1cm against the skin using a non-extensible steel tape in line with the umbilicus.
