Prolonged periods without food intake during pregnancy increase risk for elevated maternal corticotropin-releasing hormone concentrations

Article Abstract:

Fasting during pregnancy could increase a woman's risk of premature birth by increasing her blood level of corticotropin-releasing hormone. This hormone stimulates the pituitary to produce corticotropin, which in turn stimulates the adrenal glands to produce the stress hormone cortisol.

Second trimester folate status and preterm birth

Article Abstract:

A study is conducted to show that maternal folate status during pregnancy may be related to preterm birth. The results support the hypothesis that low folate levels during the second trimester of pregnancy are associated with an increased risk of preterm birth.

Maternal plasma corticotropin-releasing hormone associated with stress at 20 weeks' gestation in pregnancies ending in preterm delivery

Article Abstract:

Stress may be a factor in premature birth and elevated levels of corticotropin-releasing hormone (CRH) could be a marker of stress. CRH is produced by the placenta and increases substantially in the few weeks before delivery. It is believed to be one of the hormones involved in the induction of labor. Researchers measured CRH in blood samples from 524 pregnant women at various stages of pregnancy. Women who subsequently delivered prematurely had higher CRH levels as early as 18 weeks of pregnancy. These women were also more likely to score higher on tests of stress.
