Prevalence of marked overweight and obesity in a multiethnic pediatric population: findings from the Child and Adolescent Trial for Cardiovascular Health (CATCH) study.

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.

Distribution of and factors associated with serum homocysteine levels in children: Child and Adolescent Trial for Cardiovascular Health.

CONTEXT: Although evidence suggests that homocysteine is a risk factor for cardiovascular disease in adults, little information exists on homocysteine levels in children. OBJECTIVES: To describe the distribution of serum homocysteine concentrations among children and to examine the association between homocysteine levels and several characteristics, including serum levels of folic acid and vitamins B12 and B6. DESIGN: Cross-sectional analysis. SETTING: School-based cohort from California, Louisiana, Minnesota, and Texas. PARTICIPANTS: A total of 3524 US schoolchildren, aged 13 and 14 years, from the Child and Adolescent Trial for Cardiovascular Health (completed in 1994). Measurement was conducted in 1997. MAIN OUTCOME MEASURE: Nonfasting serum total homocysteine concentration. RESULTS: The distribution of homocysteine values ranged from 0.1 to 25.7 micromol/L (median, 4.9 micromol/L). Geometric mean homocysteine concentration was significantly higher in boys (5.22 micromol/L) than girls (4.84 micromol/L); blacks (5.51 micromol/L) than whites (4.96 micromol/L) or Hispanics (4.93 micromol/L); nonusers of multivitamins (5.09 micromol/L) than users (4.82 micromol/L); and smokers (5.19 micromol/L) than nonsmokers (5.00 micromol/ L). Serum homocysteine was significantly inversely correlated with serum levels of folic acid (r= -0.36; P = .001), vitamin B12 (r = -0.21; P = .001), and vitamin B6 (r = -0.18; P = .001). Serum homocysteine was not significantly associated with serum lipid levels or family history of cardiovascular disease and was only weakly related to body mass index and systolic blood pressure. After multivariate adjustment, homocysteine remained independently associated with sex, race, serum folic acid and vitamin B12 levels, and systolic blood pressure. CONCLUSIONS: The distribution of homocysteine levels in children is substantially lower than that observed for adults; however, a small percentage of children are still potentially at elevated risk for future cardiovascular disease. Serum folic acid may be an important determinant of homocysteine levels in children.

Three-year maintenance of improved diet and physical activity: the CATCH cohort. Child and Adolescent Trial for Cardiovascular Health.

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.

Are some children and adolescents in Louisiana addicted to tobacco? The Bogalusa Heart Study.

The US Surgeon General concluded that nicotine in tobacco is addictive. Few studies actually explore the nature of nicotine addiction in youth. In Bogalusa, Louisiana, surveys to assess tobacco usage were administered to 11-18 year olds according to a standardized protocol developed in 1976. In 1991-92, a special substudy explored the nature of nicotine addiction in youth. Overall, 14.7% were current cigarette smokers; however, as many as 44.3% of white females, ages 15-16, indicated they were current smokers. Twelve percent of the surveyed population purchased single cigarettes. Thirty-two percent of current smokers reported they smoke a cigarette within 30 minutes after waking up. Thirty-one percent said they would find it difficult to refrain from smoking in places where it is forbidden. And 23% said they continue to smoke cigarettes when they are ill. From the findings in this study, it is clear there are young people who are addicted to tobacco. It is important to develop prevention of tobacco usage in childhood. Those who are addicted require a carefully developed intervention program to assist them with their cessation efforts.

Predictors of overweight and overfatness in a multiethnic pediatric population. Child and Adolescent Trial for Cardiovascular Health Collaborative Research Group.

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.

School-based programs for health-risk reduction.

Based on implications from the pediatric studies of cardiovascular risk, it has become imperative that practical methods be developed to begin prevention of heart disease early in life. Schools provide an excellent setting for introducing comprehensive health education and promotion as a public health approach to the general population. A number of school-based health education programs have been developed (Heart Ahead/Heart Smart, CATCH, Gimme 5) for children in kindergarten through high school, in which education and environmental changes have been shown to be effective in promoting healthful behaviors. The effective implementation of health education depends to a large extent on the training and motivation of teachers, administrators, and food service staff. Training Institutes can be important for increasing personal awareness, disseminating information and materials, motivating health education efforts for teachers, food service staff and their students, and evaluating the health risk of school personnel.

Associations of oral contraceptive use with serum lipids and lipoproteins in young women: the Bogalusa Heart Study.

PURPOSE: Cross-sectional and longitudinal associations of serum lipids and lipoproteins with oral contraceptive (OC) use were examined among white and black women aged 18-27 years in 1985-86 and 1988-1991 in the Bogalusa Heart Study, a study of cardiovascular disease in a Southern community. METHODS: Analyses of covariance. RESULTS: In 1985-1986, white OC users had significantly (p < 0.05) higher adjusted mean total and low density lipoprotein (LDL) cholesterols, and lower high density lipoprotein (HDL) cholesterol compared with nonusers; black OC users had higher triglycerides and LDL cholesterol, and lower HDL cholesterol. In 1988-1991, white OC users had higher total cholesterol, triglycerides, and LDL cholesterol, while black OC users had higher triglycerides. OC use was unrelated to mean HDL cholesterol levels in 1988-1991; however, a lower percentage of white OC users than nonusers in 1988-1991 had HDL cholesterol levels < 35 mg/dl. Longitudinally, white OC nonusers at baseline who used OCs at follow-up had significant increases from baseline levels in total cholesterol, triglycerides, and very low density lipoprotein (VLDL) and LDL cholesterols; black women showed an increase only in LDL cholesterol. White women who stopped using OCs by follow-up had a decrease in VLDL and LDL cholesterols, and an increase in HDL cholesterol. White OC users at both exams also had a significant increase in HDL cholesterol, whereas women who began using OCs by follow-up did not. CONCLUSIONS: The unfavorable lipid profile associated with OC use was not apparent upon discontinued use. Lack of an adverse effect of OC use on HDL cholesterol at follow-up may be the result of changing formulations, and requires further examination.

Parent and physician response to children's cholesterol values of 200 mg/dL or greater: the Child and Adolescent Trial for Cardiovascular Health Experiment.

OBJECTIVE: To determine parental actions and concerns and physician responses to parental notification that a child's cholesterol value was 200 mg/dL or greater, a value recommended by the National Cholesterol Education Program to warrant physician follow-up and evaluation. METHODOLOGY: A telephone survey of parents (n = 784) and physicians (n = 117) was carried out after parental notification of a total blood cholesterol value obtained as part of measurement done while participating in the Child and Adolescent Trial for Cardiovascular Health in 96 schools located in California, Louisiana, Minnesota, and Texas. RESULTS: Only 20% of parents contacted physicians. Factors associated with this action included whether the parent was notified once or twice, the level of the cholesterol, previous cholesterol testing in the parent, and medical insurance that covered the visit. Family history of cardiovascular disease, when other factors were considered, did not increase the likelihood that a physician contact would be made. After contact with the physician, 59% of physicians reported evaluating children for cholesterol; about half reported repeating the cholesterol determination. CONCLUSION: Parental knowledge of a child's cholesterol value of 200 mg/dL or greater did not result in substantially further seeking of health care.

Cigarette smoking attitudes and first use among third- through sixth-grade students: the Bogalusa Heart Study.

OBJECTIVES: This study examined cigarette smoking attitudes, peer and parental influence, and first use among children in southeastern Louisiana. METHODS: Data from 933 children in grades 3 through 6 in the Bogalusa Heart Study (1993 through 1994) were analyzed. RESULTS: Fifteen percent of the children had tried smoking. Of these, 40% first smoked with a family member, and 46% obtained their first cigarette from a family member or from home. Correlates of ever having smoked were race, sex, having a best friend or family member who smoked, and attitudes that smoking is disgusting and that nonsmokers get better grades. CONCLUSIONS: Prevention programs should begin early and focus on family and peer influences as well as attitudes.

Outcomes of a field trial to improve children's dietary patterns and physical activity. The Child and Adolescent Trial for Cardiovascular Health. CATCH collaborative group.

OBJECTIVE: To assess the outcomes of health behavior interventions, focusing on the elementary school environment, classroom curricula, and home programs, for the primary prevention of cardiovascular disease. DESIGN: A randomized, controlled field trial at four sites with 56 intervention and 40 control elementary schools. Outcomes were assessed using prerandomization measures (fall 1991) and follow-up measures (spring 1994). PARTICIPANTS: A total of 5106 initially third-grade students from ethnically diverse backgrounds in public schools located in California, Louisiana, Minnesota, and Texas. INTERVENTION: Twenty-eight schools participated in a third-grade through fifth-grade intervention including school food service modifications, enhanced physical education (PE), and classroom health curricula. Twenty-eight additional schools received these components plus family education. MAIN OUTCOME MEASURES: At the school level, two primary end points were changes in the fat content of food service lunch offerings and the amount of moderate-to-vigorous physical activity in the PE programs. At the level of the individual student, serum cholesterol change was the primary end point and was used for power calculations for the study. Individual level secondary end points included psychological factors, recall measures of eating and physical activity patterns, and other physiologic measures. RESULTS: In intervention school lunches, the percentage of energy intake from fat fell significantly more (from 38.7% to 31.9%) than in control lunches (from 38.9% to 36.2%)(P<.001). The intensity of physical activity in PE classes during the Child and Adolescent Trial for Cardiovascular Health (CATCH) intervention increased significantly in the intervention schools compared with the control schools (P<.02). Self-reported daily energy intake from fat among students in the intervention schools was significantly reduced (from 32.7% to 30.3%) compared with that among students in the control schools (from 32.6% to 32.2%)(P<.001). Intervention students reported significantly more daily vigorous activity than controls (58.6 minutes vs 46.5 minutes; P<.003). Blood pressure, body size, and cholesterol measures did not differ significantly between treatment groups. No evidence of deleterious effects of this intervention on growth or development was observed. CONCLUSION: The CATCH intervention was able to modify the fat content of school lunches, increase moderate-to-vigorous physical activity in PE, and improve eating and physical activity behaviors in children during 3 school years.

Utility of an automatic instrument for blood pressure measurement in children. The Bogalusa Heart Study.

The Dinamap 845XT automatic blood pressure monitor, Dinamap 8100 (an update model), and two mercury sphygmomanometers were compared in 417 school-aged children examined in the spring of 1992 as part of the Bogalusa Heart Study. This study was conducted in the nearby community of Franklinton, Louisiana, to verify data obtained as part of a cross-sectional survey (1987 to 1988) of school-aged children in Bogalusa. Systolic blood pressure levels were on the average 3 mm Hg higher on the Dinamap instruments than on the sphygmomanometers. Mean levels of diastolic blood pressure using either Dinamap instrument were slightly higher until eight years of age and then were considerably lower than mercury sphygmomanometer fourth phase readings. Diastolic blood pressure levels on the Dinamap 8100 were 4 mm Hg lower than on the Dinamap 845XT. Height was identified as the predominant predictor variable of differences in diastolic blood pressure between the mercury sphygmomanometer and either Dinamap instrument. A 10% random sample of children was reexamined each screening day in the cross-sectional survey to estimate measurement errors. The diastolic readings of the Dinamap 845XT had a lower intraclass correlation (0.68) compared to the mercury sphygmomanometers (0.83 fourth phase and 0.76 fifth phase). The Dinamap offers the ease of measuring systolic blood pressure although the diastolic blood pressure appears to be biased and especially low, particularly on the new 8100 model.

Trends in cigarette smoking among children in a southern community, 1976-1994: the Bogalusa Heart Study.

Cigarette smoking among adolescents continues to be a major public health problem in the United States. Smoking trends from 1976-1977 to 1992-1994 were examined in the Bogalusa Heart Study, an investigation of cardiovascular disease risk factors among black and white, male and female adolescents in a semirural town in the southern United States. Age-race-sex specific chi 2 tests for trends over five survey periods were conducted. In almost every age group, black boys and girls were less likely to be current smokers or to have ever smoked or tried cigarettes, as compared with white boys and girls, respectively (P < 0.01). Within age groups, few significant trends in smoking status from 1976-1977 through 1992-1994 were observed among white boys and girls. Among black males and females, however, sharp decreases were observed among all age groups in the prevalence of having ever smoked or tried cigarettes (P = 0.0001) and among the older age groups in the prevalence of being a current smoker (P = 0.0001). Thus, substantial declines in the prevalence of smoking were observed among black children but not among white children. Further research is required to understand why these ethnic differences in smoking occurred so that public health programs may target further the smoking behaviors in children.

Physical and sedentary activity in school children grades 5-8: the Bogalusa Heart Study.

Physical and sedentary activity in children and adolescents has immediate health benefits and can also set a pattern that carries over into adulthood, resulting in long-term health benefits. Activity levels in a free-living biracial sample of children and adolescents, ages 9-15 yr (N = 995), were examined using a 24-h recall instrument, the Self-Administered Physical Activity Checklist. Selected sedentary activities (television watching and video-/computergame playing) were also assessed. Overall, boys were more physically active than girls and engaged in more heavy physical activity, while girls reported a larger percentage of time spent in light and moderate physical activities. Gender and, to a lesser extent, ethnic differences were seen in the types of activities reported. Although most physical activity occurred after school, children who reported no physical education class during school had less physical activity overall. There was a decrease in moderate physical activity with increasing grade levels in school and an increase in sedentary behavior. Black children reported more sedentary activity than white children, and girls reported more than boys. Although this 24-h recall method has limitations, it allows characterization of the activity of groups of children and provides useful data for policy recommendations.

Epidemiology of hypertension from childhood to young adulthood in black, white, and Hispanic population samples.

RESEARCHERS RECORDED BLOOD PRESSURE LEVELS of children and adolescents in the Bogalusa Heart Study (black and white populations) and in the Brooks Country Study (Hispanic population). Hispanic children had smaller stature, while whites and Hispanics tended to be fatter than blacks in childhood. In Bogalusa, black boys showed higher blood pressure levels. Hispanic girls showed lower systolic blood pressure than the other ethnic groups. In cultures with a high prevalence of hypertension, such as blacks in the United States, it is important to understand the effect of environmental factors like dietary intake and electrolytes and obesity on the control of hypertension.

Prediction of adult cardiovascular multifactorial risk status from childhood risk factor levels. The Bogalusa Heart Study.

There is increasing interest in identifying children at risk for later development of cardiovascular disease. The authors studied 1,457 children who were first examined as part of the Bogalusa Heart Study in 1973 and again 15 years later as young adults. Age-, race-, and sex-specific quartiles were defined for each of three risk factor variables-ponderal index (weight/height3), systolic blood pressure, and cholesterol--for both the child and adult measures. Adults were classified as clustered if they were in the top quartile for each of the variables. Clustered adults had higher levels of several risk factor variables, in addition to the criteria variables, than did nonclustered individuals. Of children who placed in the top quartile on three factors, 21.8% were clustered as adults. Only 1.1% of those with no risk factor levels in the top quartile were clustered as adults (p < 0.0001). Logistic regression was used to predict adult cluster status from childhood variables levels. All three factors were significant predictors, with blood pressure being the most powerful. This well-fitting model is easily interpretable in terms of standard deviations and can be a useful model for identifying at-risk children.

Cardiovascular risk factors among third grade children in four regions of the United States. The CATCH Study. Child and Adolescent Trial for Cardiovascular Health.

Data on cardiovascular risk factors (body mass index, triceps and subscapular skinfolds, blood pressure, serum total cholesterol, high density lipoprotein (HDL) cholesterol, and apolipoprotein B) were collected as part of the baseline examination (fall 1991) of the Child and Adolescent Trial for Cardiovascular Health, a multicenter school-based intervention study for promoting healthful behaviors. A total of 5,106 third grade children (mean age, 8.76 years) in four states (California, Louisiana, Minnesota, and Texas) were examined. After excluding 194 children of other or unknown origin, the study population consisted of 3,530 Anglo-American children, 674 African-American children, and 708 Latino children. African-American children were the tallest by 1-3 cm (p < 0.0001), while Latino children had the largest body mass index (p < 0.05). Blood pressure levels were similar for boys and girls and among the three races, but systolic levels were 2 mmHg higher in Texas than at the other sites. Serum total cholesterol levels were 5 mg/dl higher in girls than in boys (p < 0.05), while HDL cholesterol levels were 2 mg/dl higher in boys (p < 0.05). HDL cholesterol levels were highest in African-Americans (55.5 mg/dl) compared with Anglo-Americans (50.7 mg/dl) and Latinos (51.3 mg/dl) (p < 0.0001).

Association of fasting insulin level with serum lipid and lipoprotein levels in children, adolescents, and young adults: the Bogalusa Heart Study.

OBJECTIVE: To assess whether circulating insulin is a major contributor to adverse lipid profiles during the transition from adolescence to young adulthood. METHODS: The association between fasting insulin levels and serum lipid and lipoprotein levels was examined in a cross-sectional survey of 4136 young individuals aged 5 to 30 years from a biracial community. RESULTS: Fasting insulin levels were strongly and positively correlated with serum triglyceride and very-low-density lipoprotein cholesterol levels and negatively correlated with high-density lipoprotein cholesterol levels in all age groups (5 to 11, 12 to 17, 19 to 24, and 25 to 30 years). An increasing impact of insulin level on low-density lipoprotein cholesterol level was observed in young adults aged 25 to 30 years. In multivariate analysis, fasting insulin level was associated with very-low-density lipoprotein cholesterol level for most of the age groups in both races independently of age, sex, glucose levels, obesity, cigarette smoking, and alcohol intake. The independent relationship to low-density lipoprotein cholesterol level persisted in young adults aged 25 to 30 years. The independent and negative association with high-density lipoprotein cholesterol level remained in whites aged 5 to 24 years and blacks aged 19 to 24 years. When individuals were divided into tertiles according to insulin concentration and subscapular skinfold thickness, the independent effect of insulin level and obesity on lipoprotein fractions was also noted. Furthermore, a stronger association of insulin level with lipoprotein fractions was observed in obese than in lean white males. CONCLUSIONS: These data indicate that an increasing association of insulin levels with adverse lipoprotein levels in young adults, especially obese individuals, may have adverse consequence for adult cardiovascular diseases.

The emergence of clinically abnormal levels of cardiovascular disease risk factor variables among young adults: the Bogalusa Heart Study.

BACKGROUND: The Bogalusa Heart Study, a long-term epidemiologic investigation of the early natural history of atherosclerosis, was conducted for the first time in 1973-1974 on children from birth through the age of 14 in a biracial (black-white) population. METHODS: The emergence of clinically recognizable abnormalities (obesity, hypertension, and hyperlipidemia) was studied in 1,928 young adults, ages 19-32 years, examined in the 1988-1991 survey. RESULTS: The occurrence of morbid levels of cardiovascular disease risk factors varied by race and gender. The prevalence of severe overweight, body mass index > or = 31.1 kg/m2 for males and > or = 32.3 kg/m2 for females, was much higher for black women (20.1% than for white women (8.7%), black men (14.0%), or white men (11.7%). The frequency of hypertension [systolic blood pressure (BP) > or = 140 mm Hg, diastolic BP > or = 90 mm Hg, or treatment for high BP] was greatest for black women (13.9%) versus black men (10.1%), white men (6.2%), or white women (5.0%). Approximately 9.5% of the men and 6% of the women had elevated LDL cholesterol ( > or = 160 mg/dl), while elevated triglycerides ( > or = 250 mg/dl ranged from 0% in black females to 7.4% in white males. Dyslipoproteinemia related to HDL cholesterol ( < or = 35 mg/dl) was more marked among white men (16%) compared with other groups (approximately 4%). Correlations for risk factors in a subgroup of 1,587 individuals initially surveyed as children in 1973-1974 were examined as an indication of tracking over a 15-year period. Highly significant correlations were seen for obesity, blood pressure, and LDL cholesterol. CONCLUSION: Early identification of adverse levels of cardiovascular disease risk factors defined by clinical experience should help to predict and prevent future cardiovascular disease morbidity and mortality.
