Studies on type of work and physical activity have given conflicting results, but it is opined that stressful conditions, hard labor, and long hours are probably linked to preterm birth. [35] Obesity does not directly lead to preterm birth; [44] however, it is associated with diabetes and hypertension which are risk factors by themselves. [35]
The postpartum period can be divided into three distinct stages; the initial or acute phase, six to 12 hours after childbirth; subacute postpartum period, which lasts two to six weeks, and the delayed postpartum period, which can last up to six months. In the subacute postpartum period, 87% to 94% of women report at least one health problem.
Prolonged labor is the inability of a woman to proceed with childbirth upon going into labor. [1] Prolonged labor typically lasts over 20 hours for first time mothers, and over 14 hours for women that have already had children. [1] Failure to progress can take place during two different phases; the latent phase and active phase of labor. [1]
Toxoplasmosis can be acquired through eating infected undercooked meat or contaminated food, and by drinking contaminated water. [50] The risk of fetal infection is lowest during early pregnancy, and highest during the third trimester. However, in early pregnancy the outcome is worse, and can be fatal. [50]
In the ideal childbirth, labor begins on its own "at term". [17] Babies born before 37 weeks are "preterm" and at higher risk of health problems such as cerebral palsy. [4] Babies born between weeks 37 and 39 are considered "early term" while those born between weeks 39 and 41 are considered "full term". [4]
For example, if there is a gestational age based on the beginning of the last menstrual period of 9.0 weeks, and a first-trimester obstetric ultrasonography gives an estimated gestational age of 10.0 weeks (with a 2 SD variability of ±8% of the estimate, thereby giving a variability of ±0.8 weeks), the difference of 1.0 weeks between the ...

The latent stage, when the cervix is dilated less than 3–5 cm along with regular contractions, can last as long as 20 hours without being considered prolonged. The active stage, when regular contractions are accompanied with dilation greater than 3–5 cm, can also be significantly long, with anything less than 11.7 hours being considered ...
