Which is prone to premature birth? We analyzed the risk factors of premature birth in 311 cases, and considered that the main causes of premature birth were the most closely related to the following factors.

1 preterm birth and age: women under the age of 20 or more than 35 years of age were significantly higher, especially those who are less than 20 years old, the incidence of premature birth is 11 times that of 20~34 years old group.

Because the abortion to the cervix of the uterus have different degree of damage, leading to cervical incompetence, so that the rate of preterm birth increased.

The relationship between the 3 position and preterm birth: the incidence of preterm breech presentation was 20.4%, is 7 times the total rate of maternal premature.

The relationship between preterm birth and disease: 4 of pregnancy complicated with acute infectious diseases and some internal and surgical diseases, such as measles, influenza, acute infectious hepatitis, acute pyelonephritis, acute cholecystitis, acute appendicitis, pregnancy induced hypertension, heart disease, easily lead to premature delivery. Endocrine disorders, progesterone or estrogen deficiency in pregnant women, severe hyperthyroidism, diabetes, etc., can cause premature birth.

Maternal malnutrition, especially protein deficiency and vitamin E, folic acid deficiency, is also one of the causes of premature birth.

Emotional fluctuation or mental strain, can make the cerebral cortex function disorder, increased catecholamine secretion, sympathetic nerve activation and vasoconstriction, easily lead to premature delivery. Frequent sexual life in late pregnancy, easy to cause premature rupture of membranes, is a common cause of premature birth. Pregnant women smoking and excessive drinking, but also closely related to the occurrence of premature birth.
