Serum lipid and lipoprotein in infants and children and their relationship with diet
Insights
This study tracked cardiovascular risk factors in 5,000 children, finding serum lipids vary by age, race, and sex. While diet showed weak correlations, it may significantly impact long-term heart health.
Area of Science:
- Pediatrics
- Cardiovascular Health
- Nutritional Science
Background:
- Cardiovascular disease risk factors can emerge in childhood.
- Understanding pediatric serum lipids and lipoproteins is crucial for long-term health.
- Early identification of risk factors may aid in prevention strategies.
Purpose of the Study:
- To survey cardiovascular risk factor variables in children.
- To determine serum lipid and lipoprotein levels in children from birth through adolescence.
- To investigate the relationship between diet, serum lipids, and lipoproteins in children.
Main Methods:
- Survey of approximately 5,000 children from birth through adolescence.
- Determination of serum lipids and lipoproteins.
- Dietary studies on a selected sample of children.
Main Results:
- Significant variability in serum lipids and lipoproteins related to age, race, and sex.
- Obesity alters serum lipoproteins, particularly in white children.
- Consistent tracking of serum lipids and lipoproteins observed, with clustering of risk factors in older children.
- Weak correlation between dietary components and risk variables despite high-fat, high-cholesterol, high-salt diets.
Conclusions:
- Serum lipid and lipoprotein levels in children show significant variability influenced by demographic factors.
- Clustering of cardiovascular risk factors, including high cholesterol, is evident in older children.
- Further investigation into the precise role of diet in preventing adult cardiovascular disease is warranted.
Abstract:
A survey of children for cardiovascular risk factor variables has determined serum lipids and lipoproteins on some 5,000 children from birth through adolescence. Dietary studies have been conducted on a selected sample. Considerable variability of the serum lipids and lipoproteins occurs with significant relationships to age, race, and sex. Serum lipoproteins are altered with obesity especially in white children and a correlation of dietary intake of fat by infants and children had been noted with serum lipids and lipoproteins. A consistent ranking over time or tracking of the serum lipids and lipoproteins, especially beta-lipoprotein, occurs, and a clustering of multirisk factors including high levels of serum total cholesterol and beta-lipoproteins can be observed, especially in the older children. The trend toward increasing interrelationship of multirisk factors suggests an increasing environmental impact with age. The relationships of dietary components with risk factor variables are of a low order, even though children are consuming a relatively high fat, high cholesterol, high salt diet. Dietary factors are potentially the major environmental influence on the high incidence of coronary artery disease. The evidence of the relationship of diet to the serum lipid levels in children warrants further investigation in an effort to understand the precise role of diet in the prevention of adult cardiovascular disease.
