The trends and associated factors of preterm deliveries from 2001 to 2011 in Taiwan

Abstract

The rate of preterm birth has been increasing worldwide. Most preterm babies are at increased risk of central nervous system impairments as well as respiratory and gastrointestinal complications. The aim of this study was to investigate the trends in preterm birth and associated factors contributing to preterm delivery in Taiwan. Information on obstetric antecedents and risk factors of preterm birth of pregnant women was obtained from the Taiwan National Medical Birth Register database. All live births from 2001 to 2011 in Taiwan were included in this study. A total of 2,334,532 live births from 2001 to 2011 were included in this study. Overall, the proportion of preterm deliveries increased by 11.1% (from 8.2% in 2001 to 9.1% in 2011). Multiple logistic regression analyses showed that nulliparity, multiple births, maternal medical complications, maternal age <20 years or ≥40 years, and medical indication for earlier delivery were positively associated with an increased risk of preterm delivery. Nulliparous women aged younger than 20 years and older than 40 years should be recognized as at-risk for preterm birth.

Determinants of preterm birth among mothers who gave birth in East Africa: systematic review and meta-analysis

“…Age of women less than 20 years was correlated with PTB. This is comparable with other studies [22,87]. The increased risk PTB in younger age can be linked to the fact that their reproductive organs are not yet fully developed.…”

“…The contributing factors for PTB also include pregnancy interval [14], body mass Indexes(BMII) [11], antenatal care(ANC) [12,15,16], multiple pregnancy [17], antepartum hemorrhage(APH) [15],urinary tract infections(UTI) [11], premature rupture of membrane(PROM) [15,18], and pregnancy induced hypertension(PIH) [17,19]. Moreover, marital status [12], polyhydramnios or oligohydramnios and genitourinary infections [20], periodontal disease [11], ascending infection (bacteriuria) [21] and exposure to intimate partner violence (IPV) [15,22] are included in contributing factors of PTB.…”

The epidemiologic characteristics and associated risk factors of preterm birth from 2004 to 2013 in Taiwan

“…Previous studies have described that multifetal pregnancies are an important risk factor for preterm delivery [24,40]. Multifetal pregnancies will have higher rate of spontaneous delivery or preterm birth due to PROM before 37 weeks of gestation [41].…”

“…hypertension), as well as obstetric complications (e.G. placenta abruptio) during the pregnancy period [21,24].…”

“…Increased maternal age, multiple pregnanciesand medical complications are significantly associated with the risk of preterm birth. 15 In Goldenberg RL study, gestational ages were 34-36 weeks in 60-70% cases. 16 A Study by Mahajan A majority of cases gestational age was 33-34 weeks.…”
