Placental Weight Relative to Birth Weight and Long-term Cardiovascular Mortality: Findings From a Cohort of 31,307 Men and Women
Abstract
Birth weight is inversely associated with risk of adult cardiovascular disease, and evidence exists that fetal adaptation to challenges in the intrauterine environment may adversely affect long-term cardiovascular health. The placenta is in a key position to mediate such effects because adequate placental function is necessary for delivery of nutrients, oxygen, and hormones to the fetus. This prospective population study based on data from the hospital birth charts of 31,307 Norwegian men and women born between 1934 and 1959 assessed whether placental weight relative to birth weight was associated with risk of death from cardiovascular disease in adulthood. During 45 years of follow-up, 382 people died from cardiovascular disease (median age, 51.3 years). Results showed that the placenta-to-birth-weight ratio was positively associated with cardiovascular disease mortality; the sex- and cohort-adjusted hazard ratio for the highest versus the lowest third was 1.38 (95% confidence interval: 1.07, 1.77). The authors concluded that a disproportionately large placenta relative to birth weight was associated with increased risk of cardiovascular disease death. This finding suggests that placental function is important in the association of intrauterine factors with cardiovascular disease later in life.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
