Of the 56 intervention schools, half [28] receive a school-based program and half [28] receive both school-based and family-based programs.

One group of students, those that are in the 3rd grade in the 96 schools in the school year, comprise the study cohort. Cohort students in the intervention schools receive three consecutive years of behavioral health education concerning eating habits, physical activity, and tobacco use.

Evaluation methods include process, psychosocial, behavioral, and physiological measures. Data is managed and quality control assured through a coordinating center in Massachusetts. N2 - The Child and Adolescent Trial for Cardiovascular Health CATCH is a multi-center field trial funded by the National Heart, Lung, and Blood Institute, to test the efficacy of primary prevention of cardiovascular disease and the promotion of cardiovascular health with pre-adolescents.

Overview Fingerprint. Results of a recent month study involving sixth-grade elementary students showed that youths who received both health information and skills interventions had less intention to smoke and less cigarette use than youths who received no intervention or health information alone.

Prior studies using peer-led models with seventh graders report similar results. The research literature on the effects of physical activity promotion is sparse.

One of the few intervention studies on physical activity with school children to report increased endurance fitness and reduced body fat associated with an intensive daily physical program is the Australian Health and Fitness Study.

This randomized, controlled trial was designed to compare the effects of integrated physical activity and health education programs on body fat, blood pressure, and endurance fitness in year-old school children in primary schools located in Adelaide.

The Oslo Youth Study was successful in designing and implementing within the school system a comprehensive health educational program involving grades Positive results were obtained in the intervention group relative to the reference group with reductions in smoking onset, improved eating habits, and increased physical activity over a two-year period. Over the past ten years, school-based research studies have become more theoretically-grounded and have employed more sophisticated research design strategies and measurement techniques.

The prevention of cigarette smoking has been the major focus of this research. There is still considerable need to build the base of scientific knowledge about the development of dietary, smoking, and exercise habits during childhood and about the interventions that are effective in school settings. CATCH consisted of a three-and-a-half year feasibility study conducted from September through March , the main trial beginning in April , and the Tracking Study, in a follow-up study to allow measurements on the cohort through ages 13 to 14 years.

The purpose of the feasibility study was to test the acceptability of the interventions and measurements in 1, third, fourth, and fifth grade boys and girls, ages 7 to The main components of the Phase I intervention programs at the eight schools included classroom curricula for the third, fourth, and fifth grades; home curricula designed to involve parents and children in CATCH activities at home and family fun nights to enhance family involvement; a physical activity program centered around a new physical activity curriculum; and a school nutrition program for school food service directors and staff.

Blood samples were obtained from 1, children during risk factor screening. Other measurements included blood pressure, height, weight, triceps, and subscapular skinfolds. Nutrient intake was pilot-tested with an interactive hour recall approach, supplemented by food records, a home food inventory, and follow-up calls to parents.

Physical activity was measured with a physical activity interview and the Caltrac motion sensor. The main trial or Phase II, beginning in and ending in , included two study groups, an Intervention Group and a Control Group, with a total of approximately 8, students. The measurement cohort included 5, students.

The Intervention Group received a school-based program consisting of the CATCH curriculum, the physical education program, the school food service program, and programs to establish smoke-free schools. One-half of the Intervention Group received the same school-based program plus a family-based program. The primary endpoints at the school level were reduction in fat and saturated fat in school lunches and increased moderate to vigorous activity in PE classes.

The primary endpoint at the student level was serum cholesterol change between the third and fifth grades. Secondary endpoints included health knowledge, self-efficacy and behavioral skills that related to the adoption and maintenance of cardiovascular health behaviors; dietary fat intake; dietary sodium intake; physical activity; and systolic blood pressure. The unit of randomization was the elementary school.

Schools were recruited for participation and then randomly assigned to the study groups. Twenty-four schools were recruited from each of the four participating field centers for a total of 96 schools.

In each center, ten of 24 schools were assigned to the Control Group and 14 to the Intervention Group. Among the 14 intervention schools, seven were randomly assigned to the school-based intervention alone and seven to the school-based and family component. Measures of behavioral outcome and process variables were made during each grade from three through five.

Physiological measurements were made at baseline in grade three and at the end of grade five. Final measurements were completed in May Close-out and final data analysis were conducted in the latter part of and in Ten major mainstream papers were published in Preventive Medicine in The objectives were to measure the effects of CATCH II intervention programs on subsequent smoking prevalence rates during the end of the eighth grade and to observe the onset, development, and inter-correlation of cardiovascular risk factors from early to middle adolescence in the cohort.

Psychosocial measures, dietary fitness, and smoking data were collected annually. The full panel of physiological measures and biochemical validation of smoking was conducted during the last semester of eighth grade.

The study was active through November under UHL, the coordinating center. The substudy used serum samples collected in eighth graders in the spring of for analyses of homocysteine, folic acid, vitamin B, vitamin B-6, lipids, lipoproteins, blood pressure, weight and height.

A mail survey was conducted to collect data on the children's family history of cardiovascular disease and vitamin supplementation. The results paper was published in JAMA in It's purpose was to assess the degree to which CATCH intervention goals reduction of fat and saturated fat in school meals, increase in physical activity, no tobacco use, and implementation of the CATCH curriculum were maintained or institutionalized in the original 56 CATCH intervention schools and in 20 control schools.

To determine the influence of secular trends, the outcome measures were also assessed in 12 newly recruited unexposed schools. Measures of school climate, teacher and staff characteristics, school turbulence and school facilities and resources were assessed to help explain the variation in the degree of institutionalization in the CATCH intervention and control schools.
