RESUMO
The goal of the study was to determine whether overweight or overfatness were predicted from sex, race or ethnicity, school site, and intervention or control status for children who were 9 y old at the outset of the Child and Adolescent Trial for Cardiovascular Health (CATCH). In this ethnically and geographically diverse group of 5106 students, height, weight, and triceps skinfold thickness were measured at 9 (baseline) and 11 y (follow-up) of age. The strongest predictors of status at follow-up were baseline overweight (odds ratio: 69.0; 95% CI: 54.9, 96.3) and overfatness (odds ratio: 27.4; 95% CI: 22.4, 33.4); site, African American race or ethnicity, and male sex were also significant independent associations. Children in the overweight (> 85th percentile for body mass index) group had significantly higher adjusted means for total blood cholesterol, higher apolipoprotein B concentrations, lower mean HDL-cholesterol concentrations, and lower performance on the 9-min run than those in other groups (< 15th, 15-49th, or 50-85th body mass index percentiles). Similar results were found for these factors for those subjects with greater triceps skinfold-thickness measurements. Groups of children who were overweight and overfat at baseline were more likely to be overweight and overfat at follow-up and to have more cardiovascular risk factors than their peers.

Daily school attendance has been suggested as a health status measure for children. The present study compares school absence in children known to have asthma (N = 95) with a random sample of nonasthmatic elementary schoolchildren (N = 711). The differences in average percentage of days absent over one year were analyzed by comparing both groups' conditioning on ethnicity, sex, socioeconomic status, and grade. Children with asthma have a significantly higher absentee rate (absent 8.4% of days) than do nonasthmatic children (absent 5.9% of days) (P less than 9001). This significant difference holds true regardless of ethnicity of sex and for most socioeconomic groups. A comparison by grade level shows a similar trend for children with asthma and nonasthmatic children: absentee rates decrease as children get older; however, except for one grade level, children with asthma have a greater percentage of school days absent. Mean absentee rates for children with asthma were different when compared according to their mother's perception of severity of asthma--mild (6.9%), moderate (7.9%), and severe (13.9%).

This research developed and determined the psychometric characteristics of a measure of self-efficacy expectations (a social cognitive theory construct) for the self-management of cystic fibrosis (CF). Items for the original instrument were sampled from 150 self-management performance objectives for CF that represented behaviors in eight domains of CF care, including aspects of medical care, coping, and communication. The instrument was administered to 199 parents of children and adolescents with CF from two CF centers. The findings support a multidimensional structure for self-efficacy consistent with the multiple types of behavior required for the management of a chronic illness such as CF. An alpha-factor analysis yielded solutions clearly reflecting five theorized aspects of self-management: medical judgment and communication, coping, family communication, compliance, and acceptance. The first factor of the caretaker's scale most closely represents the underlying conceptualization of self-management as requiring self-monitoring of health status and collaboration with the health care provider in making judgments about treatment. The unit weighted factors exhibited high internal consistencies (Cronbach's alpha-factors ranging from 0.73 to 0.88).

OBJECTIVE: To evaluate Watch, Discover, Think and Act (WDTA), a theory-based application of CD-ROM educational technology for pediatric asthma self-management education. DESIGN: A prospective pretest posttest randomized intervention trial was used to assess the motivational appeal of the computer-assisted instructional program and evaluate the impact of the program in eliciting change in knowledge, self-efficacy, and attributions of children with asthma. Subjects were recruited from large urban asthma clinics, community clinics, and schools. Seventy-six children 9 to 13 years old were recruited for the evaluation. RESULTS: Repeated-measures analysis of covariance showed that knowledge scores increased significantly for both groups, but no between-group differences were found (P: = 0.55); children using the program scored significantly higher (P: < 0.01) on questions about steps of self-regulation, prevention strategies, and treatment strategies. These children also demonstrated greater self-efficacy (P: < 0.05) and more efficacy building attribution classification of asthma self-management behaviors (P: < 0.05) than those children who did not use the program. CONCLUSION: The WDTA is an intrinsically motivating educational program that has the ability to effect determinants of asthma self-management behavior in 9- to 13-year-old children with asthma. This, coupled with its reported effectiveness in enhancing patient outcomes in clinical settings, indicates that this program has application in pediatric asthma education.

OBJECTIVES: To increase pediatric residents' knowledge of the Guidelines for the Diagnosis and Management of Asthma (GDMA) developed by the Expert Panel of the National Asthma Education Program and to increase the residents' confidence in their ability to implement these guidelines. Emphasis was placed on the diagnosis and treatment of Hispanic children with asthma, a population at increased risk for morbidity. SETTING: A continuity care clinic located in an urban ambulatory care facility. SUBJECTS: Forty-four pediatric residents: 17 first-year residents, 15 second-year residents, and 12 third-year residents. METHODS: Residents participated in a multicomponent asthma management curriculum that stressed active learning strategies, including the following: focus groups, computer-based testing, lectures, hands-on skill development seminars, role modeling by attending pediatricians, provision of GDMA pocket cards and posters, access to peak flowmeters and spirometry, and an interactive computer-based module. Content focused on pulmonary function testing with spirometry and peak flowmeters, stepwise use of medications, recognition of asthma symptoms and triggers, and cultural considerations that impact asthma management. Pediatric faculty and fellows also participated in a series of asthma seminars to increase the likelihood that faculty would role model the GDMA and provide appropriate feedback to residents. RESULTS: Pediatric residents demonstrated significant increases in knowledge about evaluation of asthma, pulmonary function testing, and clinical management, displayed significantly enhanced levels of confidence, and were enthusiastic about the asthma management curriculum, rating it significantly higher than 15 other content areas in the general pediatric curriculum.

OBJECTIVE: To assess differences through grade 8 in diet, physical activity, and related health indicators of students who participated in the Child and Adolescent Trial for Cardiovascular Health (CATCH) school and family intervention from grades 3 through 5. DESIGN: Follow-up of the 4-center, randomized, controlled field trial with 56 intervention and 40 control elementary schools. PARTICIPANTS: We studied 3714 (73%) of the initial CATCH cohort of 5106 students from ethnically diverse backgrounds in California, Louisiana, Minnesota, and Texas at grades 6, 7, and 8. RESULTS: Self-reported daily energy intake from fat at baseline was virtually identical in the control (32.7%) and intervention (32.6%) groups. At grade 5, the intake for controls remained at 32.2%, while the intake for the intervention group declined to 30.3% (P<.001). At grade 8, the between-group differential was maintained (31.6% vs 30.6%, P = .01). Intervention students maintained significantly higher self-reported daily vigorous activity than control students (P = .001), although the difference declined from 13.6 minutes in grade 5 to 11.2, 10.8, and 8.8 minutes in grades 6, 7, and 8, respectively. Significant differences in favor of the intervention students also persisted at grade 8 for dietary knowledge and dietary intentions, but not for social support for physical activity. No impact on smoking behavior or stages of contemplating smoking was detected at grade 8. No significant differences were noted among physiologic indicators of body mass index, blood pressure, or serum lipid and cholesterol levels. CONCLUSION: The original CATCH results demonstrated that school-level interventions could modify school lunch and school physical education programs as well as influence student behaviors. This 3-year follow-up without further intervention suggests that the behavioral changes initiated during the elementary school years persisted to early adolescence for self-reported dietary and physical activity behaviors.

We administered a food frequency instrument to third-fifth grade students (n = 943) in four Texas schools. Comparison of foods reported on the food frequency questionnaire and on 24-hour dietary recalls (n = 7) produced a percent agreement of 83.3. The most frequent 25 foods accounted for 64.0% of food choices across all meals, 93.5% of breakfast choices, 76.4% of lunch choices, 70.5% of supper choices, and 76.0% of snack choices. Breads, milk, hamburger or steak, soda pop, tomato sauce or tomatoes, and cheese were the most frequently consumed foods. Fruits and juices accounted for 6.1% of total selections for boys and 6.6% for girls, while vegetables accounted for 15.7% of total selections for boys and 16.2% for girls. Fruit was more likely to be consumed for snacks than for meals, and vegetables were consumed in about the same frequency at lunch and supper and for snacks. We analyzed the total fat, saturated fat, and sodium content of the most frequently consumed foods. Seventeen of the top 25 foods for the total day and 13-16 for each meal or snack exceeded by at least 50% the recommended levels for fat, saturated fat, or sodium. The pattern of consumption was one of frequent consumption of a relatively small number of foods, many of which are high in fat or sodium.

Students for Peace is a three-year project (October 1993- September 1996) designed to evaluate a comprehensive, school-based intervention that seeks to prevent violence among sixth-, seventh-, and eighth-grade students in a large urban school district in Texas. This study examines the hypothesis that students exposed to a two-year multiple-component intervention will reduce aggressive behavior compared to students who receive the district's "usual care" of violence prevention activities. Students for Peace is based largely on Social Learning. Theory (SLT), which addresses both the psychosocial dynamics underlying health behavior and the methods of promoting behavior change, while emphasizing cognitive processes and their effect on behavior. SLT explains human behavior in terms of a model in which three factors-behavior, social-environmental influences, and personal factors (such as personality, perceptions and expectations, and affect)-all interact. Theoretically, an individual's behavior is uniquely determined by a combination of these factors; thus, these factors become the elements for intervention strategies. The intervention program includes four main components: (1) modification of the school environment, (2) a violence-prevention curriculum, (3) peer leadership, and (4) parent education. Students for Peace is using a nested cross-sectional and cohort design in which school is the unit of design, allocation, and analysis. Eight schools, four intervention and four control, are participating. In May 1994, a questionnaire was administered to all students in school the day of the survey. A posttest evaluation was taken in the spring of 1995 and will be followed by a final posttest in spring 1996. A total of 8,865 students responded to the baseline survey. Nearly all variables indicated comparability between treatment and control conditions. As a population, Students for Peace participants are largely Hispanic (65%) or African American (19%). Violence-related variables indicated 30-day fighting prevalence, 23%; 12-month prevalence of injuries due to fighting, 14%; 30-day hand-gun carrying prevalence, 11%; 30-day prevalence of taunts and threats at school, 27%, and threats going to and from school, 26%. Overall, the data from Year 1 activities indicate a population in need of violence-prevention intervention. The challenge is to mold existing district resources into a theoretically sound program of interventions. If that program is found effective, the district will already have the necessary documentation, personnel, and skills for broader dissemination.

BACKGROUND: Substantial differences exist in how and where physical education (PE) is conducted in elementary schools throughout the United States. Few effectiveness studies of large-scale interventions to improve PE have been reported. DESIGN: Multicenter randomized trial. SETTING/ PARTICIPANTS: The Child and Adolescent Trial for Cardiovascular Health (CATCH) was implemented in PE classes in 96 schools (56 intervention, 40 control) in four study centers: California, Louisiana, Minnesota, and Texas. INTERVENTION: The 2.5-year PE intervention consisted of professional development sessions, curricula, and follow-up consultations. MAIN OUTCOME MEASURES: Intervention effects on student physical activity and lesson context in PE were examined by teacher type (PE specialists and classroom teachers) and lesson location (indoors and outdoors). RESULTS: Differential effects by teacher type and lesson location were evidenced for both physical activity and lesson context. Observations of 2016 lessons showed that intervention schools provided more moderate-to-vigorous physical activity (p=0.002) and vigorous physical activity (p=0.02) than controls. Classroom teachers improved physical activity relatively more than PE specialists, but PE specialists still provided longer lessons and more physical activity. Classroom teachers increased lesson length (p=0.02) and time for physical fitness (p=0.03). CONCLUSIONS: The intervention improved PE of both specialists' and classroom teachers' lessons. States and districts should ensure that the most qualified staff teaches PE. Interventions need to be tailored to meet local needs and conditions, including teacher type and location of lessons.

This investigation predicted adolescents' delay of intercourse onset from attitudes, social norms, and self-efficacy about refraining from sexual intercourse. Age, gender, ethnicity, and parental education were also examined as predictors and moderators of the relationships among the 3 psychosocial determinants and onset. The participants (N = 827), part of a cohort initially surveyed in the 9th grade, reported at baseline that they had never engaged in intercourse. The multivariable proportional hazards regression model suggested that adolescents with more positive attitudinal and normative beliefs, as well as those with a parent who graduated from college, were less likely to engage in intercourse in the follow-up period (up to approximately 2 years). Interventions that include an objective to delay onset may benefit from addressing psychosocial determinants, especially attitudes and norms about sexual intercourse.
PIP: This study predicted adolescent's delay of intercourse onset from attitudes, social norms, and self-efficacy about refraining from sexual intercourse. Age, gender, ethnicity, and parental education were also examined as predictors and moderators of the relationships among the three psychosocial determinants and onset. The longitudinal data for the study were obtained from 827 participants in the US who were part of a cohort initially surveyed in the 9th grade. These participants reported at baseline that they had never engaged in intercourse. Utilizing the multivariable proportional hazards regression model, findings suggested that adolescents with more positive attitudinal and normative beliefs were less likely to engage in intercourse in the follow-up period (up to approximately 2 years). This was also the case for those students with a parent who graduated from college. Attitudes and norms were the most robust predictors of intercourse. In addition, a relatively modest increase in either scale was predictive of a 30% reduction in the onset of future intercourse in the most conservative analytic model. Interventions that include an objective to delay onset may benefit from addressing psychosocial determinants, especially attitudes and norms about sexual intercourse.

The authors test the contention of R. Jessor's (1977) problem behavior theory that adolescent health risk behaviors comprise a single behavioral syndrome. Multidimensional scaling (MDS) and cluster analysis are used to analyze data from a statewide survey of high school students' (n = 5,537) health risk behaviors. A classical MDS analysis was calculated to test the dimensionality of the behaviors. All indicators supported a multidimensional model. An individual-differences MDS (INDSCAL) analysis revealed that a 4-dimensional solution best fit the data, with gender and racial-ethnic differences emerging in the relative salience of the dimensions. The INDSCAL dimensional coordinates for each health risk behavior were then submitted to a hierarchical cluster analysis technique. Five behavioral clusters were identified, 1 of which included many of the traditional "problem behaviors," such as smoking, unprotected sexual intercourse, and alcohol consumption. These findings support a multidimensional structure underlying adolescent health risk behavior. Implications for theory and prevention of health risk behaviors are discussed.

OBJECTIVE: Determine the prevalence of marked overweight and obesity among children in the Child and Adolescent Trial for Cardiovascular Health (CATCH), identify high risk groups, and compare findings to other recent studies. DESIGN: Cohort study. SUBJECTS/SETTING: Five thousand one hundred-six school children who were participants in CATCH at baseline (age approximately 9 years) during 1991 and 4,019 of those children who had follow-up data from 1994 (age approximately 1 years) available. METHODS: Body mass index (BMI), triceps and subscapular skinfolds, subscapular to triceps skinfold (S/T) ratio, and an estimate of body fat distribution from skinfolds was calculated. Findings were compared to population-based reference data from the First National Health and Nutrition Examination Survey, 1971 to 1973 (NHANES I), to data from the Bogalusa Heart Study, and to data from the Third National Health and Nutrition Examination Survey, 1988 to 1994 (NHANES III). RESULTS: Children in CATCH were markedly heavier and fatter than the NHANES I population and more comparable to the NHANES III population, especially those in the upper percentiles. The prevalence of obesity based on BMI and triceps skinfolds >95th percentile among CATCH children was higher in boys than in girls at both baseline (boys 9.1%, girls 8.6%) and follow-up (boys 11.7%, girls 7.2%). It was higher among African-Americans and Hispanics than whites for both sexes. S/T ratios did not differ appreciably from those observed in the NHANES I reference population, suggesting that body fat distribution was more stable over time than BMI and skinfolds. APPLICATIONS: Our findings support other recent reports that American children, especially African-American and Hispanic children, are becoming heavier and fatter. Preventive measures are warranted, especially for high-risk youth.

One hundred and ninety-nine patients and their primary caregivers at two metropolitan cystic fibrosis centers participated in a clinical trial to evaluate the effectiveness of a health education program designed to help improve self-management skills for the care of CF. The baseline data from the study was used to test a structural model that hypothesized the relationship between educational, behavioral, and health status variables. Controlling for the effects of all other variables, including demographic, self-efficacy (confidence in being able to perform a behavior) was the most important educational factor predicting self-management behavior for monitoring and treating respiratory problems. Knowledge about the management of CF was only related to the ability of caretakers to apply coping skills to problems associated with CF. The more caretakers reported performing monitoring behaviors the more likely they were to report performing self-management treatment behaviors. The findings suggest that educational interventions that focus on increased knowledge alone are not likely to be effective in improving self-management behavior for CF. Based on the structural model analyses, it is recommended that educational programs for CF patients and families address increased self-efficacy and improved monitoring skills to influence the improvement of self-management treatment for CF.

PURPOSE: To evaluate the effect of a violence prevention curriculum and of trained peer leaders on self-reported aggressive behaviors, knowledge about violence and conflict-resolution skills, self-efficacy, and attitudes among 223 6th graders. METHODS: The effect of two intervention groups (violence prevention curriculum taught by the teacher with or without the assistance of trained peer leaders) and one control group were compared. Ten 6th grade classes (four control and six intervention classes) of four middle schools participated in the study. Students were evaluated before and shortly after the implementation of the curriculum, as well as 3 months later. RESULTS: The intervention reduced self-reported aggressive behaviors among boys, but this reduction was significant only in two of the six intervention classes. Both interventions had an overall significant effect on increasing knowledge about violence and skills to reduce violence. After the intervention, students also developed a more negative attitude toward responding violently when provoked. Attitude change was stronger among students from the teacher plus peer leader group. No intervention effect was observed on self-efficacy nor on attitudes toward skills to reduce violence. Changes were not maintained over time. CONCLUSIONS: Results emphasize the need for continuous and comprehensive interventions, follow-up evaluations, and careful selection of peer leaders. Aggressive behaviors, not knowledge alone, should be used as the main dependent variable.

PURPOSE: To describe the frequency of violence-related behaviors and their association with other health behaviors among high school students. METHODS: The Youth Risk Behavior Survey was administered to all ninth and eleventh graders (n = 2075) of a school district in Texas. It provided information regarding violence-related behaviors and other health behaviors. Students were classified into four mutually exclusive, violence-related categories according to whether they were involved in a physical fight and/or carried a weapon. RESULTS: Overall, 20% of the students were involved in a physical fight but had not carried a weapon, 10% carried a weapon but had not been involved in a physical fight, and 17% had been involved in a physical fight and had carried a weapon. Prevalence of weapon-carrying and fighting were higher among males than females, and among ninth graders than eleventh graders. Among males, 48% had carried a weapon the month prior to the survey. Students who both fought and carried a weapon were 19 times more likely to drink alcohol six or more days than students who did not fight nor carried a weapon. Logistic regression analyses showed that drinking alcohol, number of sexual partners, and being in ninth grade were predictors of fighting. These three variables plus having a low self-perception of academic performance and suicidal thoughts were predictors of fighting and carrying a weapon. CONCLUSIONS: The data indicate that violence-related behaviors are frequent among high school students and that they are positively associated with certain health behaviors. Interventions designed to reduce violence should also address coexisting health-risk behaviors and target high-risk groups.

PURPOSE: The Child and Adolescent Trial for Cardiovascular Health is a multi-site study of a school-based intervention designed to reduce or prevent the development of risk factors for cardiovascular disease. The goal was to change (or prevent) related risk behaviors and the psychosocial variables that theoretically influence those behaviors. DESIGN: A nested design was used in which schools served as the primary unit of analysis. Twenty-four schools participated at each of four sites (Austin, San Diego, Minneapolis, and New Orleans). Each site had 10 control and 14 intervention schools. SETTING AND SUBJECT: Ninety-six schools (with more than 6000 students) in the four sites were randomized to three treatment conditions: control, school-based interventions, and school-plus-family interventions. The sample included approximately equal numbers of males and females and was 67.5% white, 13.9% African-American, 13.9% Hispanic, and 4.7% other. MEASURES: The psychosocial determinants included improvements in dietary knowledge, intentions, self-efficacy, usual behavior, perceived social reinforcement for healthy food choices, and perceived reinforcement and self-efficacy for physical activity. RESULTS: The findings indicated significant improvements in all the psychosocial determinants measured (p < .0001). The results revealed a greater impact in the school-plus-family intervention schools for two determinants, usual dietary behavior and intentions to eat heart-healthy foods. CONCLUSIONS: These findings support theory-based interventions for changing selected psychosocial determinants of cardiovascular disease risk behavior among children.

Performance objectives for the self-management of cystic fibrosis (CF) were developed and subjected to a two-stage content validation. A multidisciplinary team of health care professionals generated a list of 149 medical and adjustment performance objectives. Behaviors included monitoring symptoms and judging their significance, treating symptoms and communicating with health care providers about symptoms and treatment plans. In the first stage a panel of experts in the medical and behavioral aspects of CF rated each behavior. In general, the eleven panelists rated the 149 behaviors as somewhat important or important (mean 2.6, S.D. 0.17, on a 3-point scale). In the second stage, 84 of 155 CF center directors rated all behaviors as somewhat important or important (mean 2.9, S.D. 0.23). Specific behaviors related to medical regimens were more consistently rated as important than were those related to psychosocial adjustment. The performance objectives provide a framework for developing and evaluating health education programs for the self-management of CF in order to promote optimum health and adjustment.

In this report we describe the development of the Watch, Discover, Think and Act asthma self-management computer program for inner-city children with asthma. The intervention focused on teaching two categories of behaviors--asthma specific behaviors such as taking preventive medication and self-regulatory processes such as monitoring symptoms and solving asthma problems. These asthma self-management behaviors were then linked with empirical and theoretical determinants such as skills and self-efficacy. We then further used behavioral science theory to develop methods such as role modeling and skill training linked to the determinants. We matched these theoretical methods to practical strategies within the computer simulation and created a culturally competent program for inner-city minority youth. Finally, we planned a program evaluation that linked program impact and outcomes to the theoretical assumptions on which the intervention was based.

An interactive multimedia computer game to enhance self-management skills and thereby improve asthma outcomes in inner city children with asthma was evaluated. Subjects aged 6-17 were recruited from four pediatric practices and randomly assigned to the computer intervention condition or to the usual-care comparison. The main character in the game could match the subject on gender and ethnicity. Characteristics of the protagonist's asthma were tailored to be like those of the subject. Subjects played the computer game as part of regular asthma visits. Time between pre- and post-test varied from 4 to 15.6 months (mean, 7.6 months). Analysis of covariance, with pre-test scores, age, and asthma severity as covariates, found that the intervention was associated with fewer hospitalizations, better symptom scores, increased functional status, greater knowledge of asthma management, and better child self-management behavior for those in the intervention condition. Interactions with covariates were found and discussed in terms of variable efficacy of the intervention.

The practice of health education involves three major program-planning activities: needs assessment, program development, and evaluation. Over the past 20 years, significant enhancements have been made to the conceptual base and practice of health education. Models that outline explicit procedures and detailed conceptualization of community assessment and evaluation have been developed. Other advancements include the application of theory to health education and promotion program development and implementation. However, there remains a need for more explicit specification of the processes by which one uses theory and empirical findings to develop interventions. This article presents the origins, purpose, and description of Intervention Mapping, a framework for health education intervention development. Intervention Mapping is composed of five steps: (1) creating a matrix of proximal program objectives, (2) selecting theory-based intervention methods and practical strategies, (3) designing and organizing a program, (4) specifying adoption and implementation plans, and (5) generating program evaluation plans.
