“The Bogalusa Heart Study has been a long-term epidemiologic study. The investigators have identified and followed black and white participants for nearly 40 years, and have described the incidence and prevalence of biologic and behavioral cardiovascular disease risk factors from childhood through adulthood.” It further notes: “The results from the Bogalusa Heart Study have clearly documented that the genesis of atherosclerosis has its basis in childhood, and that prevention can and must begin at the early ages.”

The relation of antemortem risk factors for cardiovascular disease to early atherosclerotic lesions in the aorta and coronary arteries was assessed in those individuals previously examined in the Bogalusa Heart Study (N = 59). Aortic fatty streaks were strongly related to both total and low-density lipoprotein (LDL) cholesterol (r = 0.62, P < 0.0001 for each association), and were inversely correlated with the ratio of high-density lipoprotein (HDL) cholesterol to LDL plus very-low-density lipoprotein (VLDL) cholesterol (r = -0.29, P < 0.01). Coronary artery fatty streaks were associated with elevated total cholesterol, LDL cholesterol, VLDL cholesterol, and systolic blood pressure. These findings emphasize the importance of an approach to preventive cardiology early in life.

The abstract describes it as “a long-term epidemiologic investigation of the early natural history of atherosclerosis, conducted for the first time in 1973-1974 on children from birth through the age of 14 in a biracial (black-white) population.” It further explains that 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.” The conclusion states: “Early identification of adverse levels of cardiovascular disease risk factors… should help to predict and prevent future cardiovascular disease morbidity and mortality.”

The article states: "The Bogalusa Heart Study was begun in 1972 as an epidemiology study of cardiovascular risk factors in children and adolescents; it eventually evolved into observations of young adults." It explains that prior autopsy work on aortas from young to older individuals stimulated "an interest in studying children for early clinical evidence of major adult heart diseases," linking childhood risk factors and later atherosclerotic disease.

The Collaborative Pathology Study is one of the most impressive programs of the Bogalusa Heart Study. Attempts are made to obtain complete and uniform necropsy coverage of all deceased young people who may have been examined in the Bogalusa Heart Study. Since 1978, autopsy specimens have been collected from 190 deaths, representing 65% of all known deaths in the study age category. The relation of antemortem risk factors for cardiovascular disease to early atherosclerotic lesions in the aorta and coronary arteries was assessed in those individuals previously examined in the Bogalusa Heart Study.

The abstract states: “Cardiovascular risk factors begin in childhood and are predictive of cardiovascular risk in adulthood. Observations in the Bogalusa Heart Study have shown an important correlation of clinical risk factors in early life with anatomic changes in the aorta and coronary vessels with atherosclerosis and cardiac and renal changes related to hypertension.” It continues: “These observations have been extended by echo Doppler studies of carotid artery intima-media thickness (IMT). A close association of risk factors in young adults, 20–38 years of age, occurs with IMT, and a marked increase is noted as numbers of risk factors increase.”

In this NEJM paper led by Berenson, the authors report on autopsies of young individuals from Bogalusa: “Body-mass index, systolic and diastolic blood pressure, and serum concentrations of total cholesterol, triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol were strongly associated with the extent of lesions in the aorta and coronary arteries.” They conclude: “These findings indicate that the atherosclerotic process begins in childhood and that the extent of atherosclerosis in young people is directly related to the presence and severity of cardiovascular risk factors and obesity.”

In the Bogalusa Heart Study, autopsies were performed on 93 persons aged 2 to 39 years who had died of external causes and for whom cardiovascular risk factor data were available. The extent of fatty streaks and fibrous plaques in the aorta and coronary arteries increased significantly with the number of risk factors present, including elevated serum lipoproteins, hypertension, obesity, and smoking. These findings support the concept that atherosclerosis begins in childhood and that risk factors identified in youth are associated with the severity of atherosclerosis.

The ACC synopsis notes: “The Bogalusa Heart Study is a long-term epidemiologic study of cardiovascular risk factors from birth through the age of 38 years in a biracial population (65 percent white and 35 percent black).” It states that “these studies have established that the major adult cardiovascular diseases (coronary-artery disease and essential hypertension), begin in childhood.” In the interpretation section, it concludes: “The Bogalusa Heart Study now establishes that precursors of adult cardiovascular diseases begin in childhood. The clearest evidence comes from autopsy studies that show coronary atherosclerotic lesions occur in early life and are strongly associated with very-low-density lipoprotein cholesterol, systolic and diastolic blood pressure, and obesity… The demonstration of cardiovascular disease in early life gives credibility to risk-factor examination of children and the need for beginning of prevention in early life.”

The study reports that “both the PDAY study and the Bogalusa Heart Study have shown that atherosclerosis begins in childhood and its extent and severity are related to the presence and intensity of known cardiovascular risk factors.” It finds that “carotid IMT in asymptomatic healthy young adults is associated with traditional cardiovascular risk factors measured since childhood. The LDL-C level and BMI in childhood; LDL-C, HDL-C, and systolic blood pressure in adulthood; and cumulative burden of LDL-C and HDL-C levels since childhood were independent risk factors for having increased carotid IMT in young adulthood.” The authors conclude: “The single measurement of LDL-C level in childhood is predictive of adult changes in IMT of carotid vessels and by inference in coronary arteries.”

Researchers with the Bogalusa Heart Study conducted autopsies and obtained risk factor data on 93 people from two to 39 years of age who had died accidentally, from homicide or suicide or sudden infant death syndrome. The researchers found that the more cardiovascular risk factors a person had, the greater the extent of fatty streaks and fibrous plaques in the arteries. They concluded that atherosclerosis begins in childhood and that risk factors present early in life are associated with the severity of atherosclerotic lesions.

The abstract summarizes: “Observations in the Bogalusa Heart Study have shown an important correlation of clinical risk factors in early life with anatomic changes in the aorta and coronary vessels with atherosclerosis and cardiac and renal changes related to hypertension.” It further notes: “Cardiovascular risk factors begin in childhood and are predictive of cardiovascular risk in adulthood.” The paper emphasizes that noninvasive measurements like carotid intima-media thickness in young adults are closely associated with earlier life risk factor levels, supporting the concept that subclinical cardiovascular disease has childhood origins.

This longitudinal analysis of Bogalusa participants notes: “The Bogalusa Heart Study is a long-term epidemiologic study in a biracial (black-white) community designed to investigate the early natural history of cardiovascular disease.” It reports that “cardiovascular risk factors measured in childhood track into young adulthood” and that “those with higher levels of blood pressure, cholesterol, and body mass index in childhood tended to maintain higher levels as young adults,” supporting the idea that childhood risk affects adult cardiovascular profile.

The article states: "The Bogalusa Heart Study now establishes that precursors of adult cardiovascular diseases begin in childhood." It notes that "the clearest evidence comes from autopsy studies" linking early arterial changes with later cardiovascular disease. The rationale discusses how studying children in Bogalusa was designed to understand "the early natural history of heart disease" before clinical symptoms appear.

The Bogalusa Heart Study is a long-term community-based study that has followed cohorts of children in Bogalusa, Louisiana, into adulthood to examine the evolution of cardiovascular risk factors. Serial cross-sectional and longitudinal examinations have documented the tracking of serum lipids, blood pressure, and obesity from childhood to adult life, and their relation to subclinical atherosclerosis. The authors emphasize that evidence from the Bogalusa Heart Study indicates that the pathogenesis of atherosclerosis and its major risk factors begins in childhood.

This article explains: “The Bogalusa Heart Study is a long-term study of a biracial (65% white, 35% black) community in Bogalusa, Louisiana, designed to examine the natural history of cardiovascular risk factors from childhood into adulthood.” It reports that “overweight children were more likely than normal-weight children to have multiple cardiovascular risk factors” and that “childhood obesity was associated with adverse levels of blood pressure, lipids, and insulin in young adulthood,” demonstrating that childhood weight status is linked with adult cardiovascular risk profiles.

The page notes: “Since 1973, the Bogalusa Heart Study has been at the forefront of cardiovascular research, revealing groundbreaking insights into how heart disease begins in childhood.” It states that “The Bogalusa Heart Study was the first to demonstrate that heart disease starts in childhood, changing how we approach pediatric health.” It also emphasizes that the study “meticulously followed the health of local children into their adult years” and “has shown that childhood factors like obesity, diet, and physical activity impact heart disease risk later in life.”

Using data from the Bogalusa Heart Study, childhood levels of cardiovascular risk factors such as serum lipoproteins, blood pressure, and adiposity were related to carotid artery intima-media thickness measured in adulthood. The study found that higher levels of these risk factors in childhood were significantly associated with thicker carotid intima-media in adult participants, indicating subclinical atherosclerosis. The authors conclude that atherosclerotic cardiovascular disease has its origins in childhood and that early-life risk factor exposure influences arterial structure later in life.

Describing the program’s history, the site states: “Over five decades, it transformed our understanding of heart disease prevention in children.” It highlights a central finding: “The study proved for the first time that heart disease begins in childhood, not adulthood. It found that high blood pressure, high cholesterol, and obesity in children—especially when left unaddressed—are strong predictors of cardiovascular disease later in life.”

The article characterizes the Bogalusa Heart Study as “a long-term population study with a continued relationship with a community,” addressing cardiovascular risk in a biracial rural environment. It discusses evidence of “structural and functional changes related to risk factors, such as hypertension and parental history of cardiovascular disease” and notes that these parental cardiovascular events serve “as a surrogate measure of future heart disease” in the children. Carotid artery studies and related measures are used to link childhood risk factors to early vascular changes.

Tulane’s article explains: “The Bogalusa Heart Study, which tracked the health of the town’s children into adulthood, found for the first time that heart disease begins in childhood.” It adds that the community-wide study “pioneered a new approach to pediatrics by proving that high blood pressure and high cholesterol in children doesn’t fade with age, with no intervention, and could result in hypertension and heart disease later in life.”

The overview explains that "the study’s original goal may have been to find a link between age and the development of heart disease, but it gradually grew to include much more." It notes that the study "started with thorough data collection and in-depth evaluations of children’s daily routines, meals, and physical activity" and that the Bogalusa Heart Study "has revolutionized our understanding of cardiovascular disease by revealing that it begins in childhood." It describes continuing follow-up of participants and expansion into brain health research.

The research overview notes: “The Bogalusa Heart Study is one of the longest-running epidemiological investigations in the United States, focused on a biracial, semi-rural community in Bogalusa, Louisiana.” It describes that the study was “initiated to explore the long-term effects of cardiovascular and metabolic changes on health throughout the lifespan” and that its contributions “have provided invaluable insights from both cross-sectional and longitudinal perspectives on over 12,000 children and adults in Bogalusa.” It emphasizes examining “how early life exposures and behaviors affect health across an individual’s lifetime.”

LSU’s research magazine reports: "The landmark Bogalusa Heart Study, named for the town in which it originated, was one of the first long-term studies to track the health outcomes of people from childhood all the way through adulthood." It emphasizes that "the rich dataset reveals that health experiences early in life might impact health outcomes across the lifespan." It also notes that the study "followed and collected the blood pressure and cholesterol levels of the participants at least every two years from childhood through adulthood" and that most participants are now in middle age.

The Bogalusa Heart Study is described as a long-term epidemiologic study of cardiovascular risk factors from childhood through adulthood. Autopsy specimens were collected from over 100 deceased children and young adults, of whom approximately forty percent had been previously examined in the Bogalusa Heart Study. The Pediatric Pathology Risk Factor Program documented the relationship of cardiovascular disease risk factors to anatomic and pathologic changes, including early atherosclerotic lesions in the aorta and coronary arteries.

A blog entry summarizing the findings states that the Bogalusa Heart Study “was one of the first ever longitudinal studies to find that cardiovascular risk factors were detectable even at a young age, despite notions that heart disease had little to do with children.” Another post titled “The Study that Proved Heart Disease Starts in Childhood” notes: “Most people used to think heart disease had nothing to do with kids. But the Bogalusa Heart Study shattered this myth. This long-term study, founded in 1973 by Dr. Gerald Berenson, was the first to prove that heart disease in…” and goes on to describe early signs and prevention decades before diagnosis.

The listing describes: “The Bogalusa Heart Study has been a long-term epidemiologic study.” It notes “on-going follow-up of heart disease risk factors and related outcomes,” indicating continued surveillance of participants’ cardiovascular risk factors and clinical outcomes over time.

This clinical summary explains: “The Bogalusa Heart Study was initiated in 1972 in Bogalusa, Louisiana and stands as the longest running biracial study of children, focused on identifying early contributors to coronary artery disease and hypertension.” It notes that in one classic analysis, “children recruited for weight and cardiovascular risk assessment were found to have higher frequencies of cardiac risks factors as their BMIs increased,” and that “being overweight was considered an effective screening tool for cardiovascular risk with over 50% of overweight participants having at least 1 risk factor.” The article emphasizes that these childhood risk patterns are relevant because they track into adult cardiovascular risk.

In cardiovascular epidemiology, the Bogalusa Heart Study is widely cited as a foundational longitudinal cohort that began with children in the early 1970s and repeatedly followed them into adulthood. Its publications documented that traditional cardiovascular risk factors such as obesity, elevated blood pressure, and dyslipidemia often track from childhood to adult life and are associated with subclinical atherosclerotic changes (e.g., carotid intima-media thickness), supporting the concept that cardiovascular disease processes can begin in childhood.
