Official title: LA Health: A Prospective Study of Primary and Secondary Obesity Prevention in Children and Adolescents
There is a worldwide pandemic of obesity with far-reaching consequences for the health of our nation. Obesity is the second leading cause of preventable death in the United States. Prevention of obesity, especially in children, has been deemed by public health policy makers to be one of the most important objectives for our country.
Read the detailed description
There is a worldwide pandemic of obesity with far-reaching consequences for the health of our nation. Obesity is the second leading cause of preventable death in the United States. Prevention of obesity, especially in children, has been deemed by public health policy makers to be one of the most important objectives for our country. Obesity disproportionately affects citizens of minority and low socioeconomic status. A consensus of opinion has formed that the recently observed increased prevalence of obesity is caused by environmental and behavioral factors that favor easy access to high calorie foods and sedentary behavior. This prevention project, called LA Health, will test whether modification of these environmental and behavioral factors can prevent inappropriate weight gain in children who are enrolled in the fourth to sixth grades during Year 1. The primary aims of the LA Health project are to test the efficacy of two school-based approaches for obesity prevention. The two approaches are derived from two NIH-funded pilot studies called the HIPTeens project (a secondary prevention program) and the Wise Mind project (a primary prevention program). The study will test the efficacy of primary prevention alone and a combination of primary and secondary prevention in comparison to a no-treatment control group using a cluster randomization research design, with 18 school clusters from 9 different parishes randomly assigned to the three treatment arms. The following parishes were selected for the project: East Carroll, Madison, Franklin, East Feliciana, St. John, St. Helena, Pointe Coupee, Avoyelles, and Sabine Parishes. Thus far East Carroll, East Feliciana, St. John, Pointe Coupee, and Avoyelles Parishes have agreed to participate. We anticipate adding additional parishes in the second year of the project.The project will collaborate with a USDE funded project, LA GEAR UP, to test the relative efficacy obesity prevention programs for children who come from economically disadvantaged environments. The LA GEAR UP program is designed to enhance educational achievement. Since LA GEAR UP will be implemented in all 18 school clusters, all of the preventions intervention arms, including no-treatment, will be combined with an academic enhancement program. The study will span three years and will provide critical tests of strategies that modify the child's environment as a primary prevention strategy and provide health behavior modification via classroom instruction and internet counseling as a secondary prevention strategy. The study will also recruit a similar (but smaller) sample of students to measure changes in body weight relative to height, gender, and age over the same three-year period. This observation only control group will be studied to evaluate secular trends in changes in body weight so that body weight changes observed in the randomized trial can be interpreted within the context of stable versus unstable population changes in body weight. The results of this investigation will significantly impact public health policy related to obesity prevention in rural communities, minority communities, and in children from families that are economically disadvantaged.

What is being measured
The primary outcome is the main question the study is designed to answer.
% Body Fat (Boys)
change in percent body fat between Baseline and 3 years for boys
Measured: Baseline and 3 years
BMI Z-score (Boys)
Body mass index z-scores are measures of relative weight adjusted for child age and sex. The Z-score indicates the number of standard deviations away from a reference population in the same age range and with the same sex. A Z-score of 0 is equal to the mean. Negative numbers indicate BMI values lower than the mean and positive numbers indicate BMI values higher than the mean
Measured: Baseline and three years
% Body Fat (Girls)
change in percent body fat between Baseline and 3 years for girls
Measured: Baseline and 3 years
BMI Z-score (Girls)
Body mass index z-scores are measures of relative weight adjusted for child age and sex. The Z-score indicates the number of standard deviations away from a reference population in the same age range and with the same sex. A Z-score of 0 is equal to the mean. Negative numbers indicate BMI values lower than the mean and positive numbers indicate BMI values higher than the mean

Questions about this trial
What is this clinical trial studying?
A study testing Primary (Environmental) Weight Gain Prevention and Secondary (Behavioral) Weight Gain Prevention in people with Childhood Obesity, run by Pennington Biomedical Research Center at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 10 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 12 Jun 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
% Body Fat (Boys) (time frame: Baseline and 3 years). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00289315, which also lists 9 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jul 2018.
