Insights
Fetal growth conditions impact adult coronary heart disease (CHD) risk in Chinese populations. Lower birth size, indicating fetal growth restriction, is linked to increased CHD occurrence later in life.
Area of Science:
- Cardiovascular Epidemiology
- Developmental Origins of Health and Disease (DOHaD)
Background:
- Clinical studies suggest a link between fetal growth and adult coronary heart disease (CHD).
- No prior studies have investigated this association within a Chinese population.
Purpose of the Study:
- To examine the relationship between neonatal birth characteristics and the incidence of CHD in a Chinese cohort.
Main Methods:
- Retrospective cohort study of 2,033 individuals born between 1921 and 1954 at Peking Union Medical College Hospital.
- Collected neonatal data included birth-weight, placental weight, length, and head circumference.
- Follow-up occurred from May 2002 to April 2004 to ascertain CHD occurrence.
Main Results:
- Coronary heart disease (CHD) was diagnosed in 135 patients.
- Higher birth-weight, head circumference, and placental weight were inversely associated with CHD risk (P < 0.05).
- The ratio of birth-weight to birth length emerged as an independent predictor of CHD, alongside obesity and age.
Conclusions:
- Low birth size or disproportion, indicative of fetal growth retardation, is associated with adult CHD in China.
- This highlights the influence of both prenatal and postnatal environmental factors on CHD development.
Background:
Clinical epidemiological studies suggested a link between fetal growth conditions and later coronary heart disease (CHD) in adult life. However, no such studies have been conducted in a Chinese population.
Objectives:
We investigated the association between various birth characteristics and CHD occurrence in a Chinese cohort.
Design:
Retrospective cohort study.
Setting:
Peking Union Medical College Hospital, Beijing, China.
Participants:
A total of 2,033 subjects who were born at Peking Union Medical College Hospital between 1921 and 1954.
Measurements:
Neonatal birth-weight, placental weight, length from crown to heel, head circumference, and biparietal and occipitofrontal diameters were routinely recorded at the time of birth. All participants were followed up between May 2002 and April 2004 for the occurrence of CHD.
Results:
CHD was identified in 135 patients. The occurrence of CHD was inversely related to birth sizes, such as birth-weight, head circumference, placental weight (P < 0.05), but was not significantly related to birth length or ponderal index (birth-weight/birth length(3)). After multivariable logistic regression, the ratio of birth-weight to birth length was an independent predictor of CHD along with two other variables: obesity and age.
Limitations:
This was a single-center retrospective study.
Conclusions:
In China low birth size or birth disproportion, which is suggestive of fetal growth retardation, has an effect on CHD occurrence during adulthood. This suggests that environmental factors operate in both the prenatal and postnatal periods with regard to the development of CHD.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
