Prevalence and Incidence of Bronchopulmonary dysplasia
Bronchopulmonary dysplasia: Rare Disease
Bronchopulmonary dysplasia is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Bronchopulmonary dysplasia, or a subtype of Bronchopulmonary dysplasia,
affects less than 200,000 people in the US population.
Ophanet, who are a consortium of European partners,
currently defines a condition rare when if affects 1 person per 2,000.
They list Bronchopulmonary dysplasia as a "rare disease".
More information about Bronchopulmonary dysplasia is available from Orphanet

Premature labor:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
The possible causes of premature labor are many; they may include premature rupture of the membranes (occurs in 30% to 50% of premature labors), preeclampsia, chronic hypertensive vascular disease, hydramnios, multiple pregnancy, placenta previa, abruptio placentae, incompetent cervix, abdominal surgery, trauma, structural anomalies of the uterus, infections (such as rubella or toxoplasmosis), congenital adrenal hyperplasia, and fetal death.
Other important provocative factors include:
❑ Fetal stimulation: Genetically imprinted information tells the fetus that nutrition is inadequate and that a change in environment is required for well-being; this provokes onset of labor.
❑ Oxytocin sensitivity: Labor begins because the myometrium becomes hypersensitive to oxytocin, the hormone that normally induces uterine contractions.
❑ Myometrial oxygen deficiency: The fetus becomes increasingly proficient in obtaining oxygen, depriving the myometrium of the oxygen and energy it needs to function normally, thus making the myometrium irritable.
❑ Maternal genetics: A genetic defect in the mother shortens gestation and precipitates premature labor.

About prevalence and incidence statistics:
The term 'prevalence' of Bronchopulmonary dysplasia usually refers to the estimated population
of people who are managing Bronchopulmonary dysplasia at any given time.
The term 'incidence' of Bronchopulmonary dysplasia refers to the annual diagnosis rate,
or the number of new cases of Bronchopulmonary dysplasia diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
