“…The incidence of C-sections in older women has been reported in other studies (4,13,(18)(19) . The chance of C-section among women older than 35 years of age was 1.23 greater than among women 20 to 34 years old.…”

“…Deterioration of the function of the myometrium caused by aging is another factor accounting for some disorders during delivery that contribute to an increased number of C-sections. Concern over C-sections is due to its link with maternal morbidity during the perinatal period, that it doubles the risk of neonatal mortality and increases placental complications in Gravena AAF, Sass A, Marcon SS, Pelloso SM subsequent pregnancies, including placenta praevia and placental abruption (18)(19) .…”

“…Risk factors associated with low birth weight are more common among older women such as arthritis, chronic hypertension, depression, cancer and acute myocardial infarction, which are factors that do not depend on fetal growth restriction (18) . All these factors need to be properly monitored during the gestational period.…”

RESUmOO objetivo do estudo foi comparar resultados perinatais de mulheres com idade igual ou superior a 35 anos com os de mulheres entre 20 e 34 anos. O estudo é retrospectivo e foi realizado a partir da consulta às fichas obstétricas de 1.255 puérperas que tiveram partos no único hospital de Sarandi-PR, no período de janeiro de 2007 a dezembro de 2008. As variáveis analisadas foram: estado civil, escolaridade, idade gestacional, tipo de parto, peso ao nascer, índice de Apgar no 1º e 5º minutos e óbi-tos fetais. Na regressão logística, a idade materna avançada esteve associada significativamente à cesariana (OR 1,23, IC 95% 0,19-0,44) e a um índice de Apgar menor que 7 no 5º minuto de vida (OR 5,78, IC 95% 0,76

“…(17,21) Among associated maternal factors, the most emphasized are arthritis; chronic blood hypertension; depression; cancer; and acute myocardial infarction, which constitute independent risk factors for fetal growth restriction. (16) Newborns born to adolescent mothers were 1.44 times more likely to present with an Apgar index of lower than seven in the first five minutes. A research study observed an association of extremely low birth weight and low five-minute Apgar index in children born to women younger than 18 years old.…”

“…(11) It is important to emphasize that the incidence of cesarean section deliveries in advanced-age pregnant women has been reported in other studies. (6,10,12,16,17) Several reasons may explain the high incidence of cesarean section in women with advanced maternal age such as diseases, obstetric indications, and fetal complications. Deterioration of myometrial function with age is another factor responsible for some delivery complications.…”

Objective: To analyze and compare perinatal outcomes of pregnant adolescent women and pregnant women in later age (between 20 and 34 years old) from data of a Live Born Information System. Methods: A cross-sectional study was carried out with data collected retrospectively of 18,009 live born infants from consults of data of a Live Born Information System. Registers of live born infants were distributed in three groups: group I (adolescents) -10 to 19 years old; group II -20 to 34 years old; and group III (later age) -35 years or older. Results: Findings showed that perinatal risks were related to prematurity (OR 1,35) and five-minute Apgar scores of less than seven (OR 1,44) among infants born to adolescent mothers. Conclusion: Results pointed out high indexes of preterm birth in low-birth-weight infants and five-minute Apgar scores of less than seven in pregnancies that occurred in adolescents and in women 35 years and older. ResumoObjetivo: Analisar e comparar os resultados perinatais de gestantes adolescentes e em idade tardia com mulheres entre 20 a 34 anos, a partir dos dados do Sistema de Informação de Nascidos Vivos. Métodos: Foi realizado um estudo transversal, com coleta de dados retrospectiva de 18009 nascidos vivos a partir de consultas aos dados do Sistema de Informação de Nascidos Vivos. Os registros dos nascidos vivos foram distribuídos em três grupos: grupo I (adolescentes) -10 a 19 anos; grupo II -20 a 34 anos e grupo III (idade tardia) -35 anos ou mais. Resultados: Os resultados mostraram riscos perinatais relacionados à prematuridade (OR 1,35) e Apgar quinto minuto menor que sete (OR 1,44) em mães adolescentes. O baixo peso ao nascer apresentou risco de 1,22 e 1,24 vezes entre as gestantes do grupo I e III. Conclusão: Os resultados apontaram elevados índices de nascimento pré-termo, baixo peso ao nascer e Apgar no quinto minuto menor que sete nas gestações ocorridas em adolescentes e em mulheres com idade igual ou superior aos 35 anos.

Objective To evaluate the risk levels for maternal and perinatal complications at > 40, > 45 and > 50 years old compared with younger controls. Methods Electronic databases were searched from their inception until March 2021. We included studies reporting pregnancy outcome in pregnant women aged 40, 45, and 50 years or older compared with controls at the time of delivery. Case reports and case series were excluded. The primary outcome was the incidence of stillbirth. Meta‐analysis was performed using the random effects model of DerSimonian and Laird, to produce summary treatment effects in terms of relative risk (RR) with 95% confidence interval (CI). Heterogeneity was measured using I2 (Higgins I2). Subgroup analyses in women older than 45 years and in those older than 50 years were performed. Results Twenty‐seven studies, including 31 090 631 women, were included in the meta‐analysis. The overall quality of the included studies was moderate to high. Most of the included studies were retrospective cohort studies (21/27), four were population‐based studies, and two were cross‐sectional studies. Women aged ≥40 years had significantly higher risk of stillbirth (RR 2.16, 95% CI 1.86–2.51), perinatal mortality, intrauterine growth restriction, neonatal death, admission to neonatal intensive care unit, pre‐eclampsia, preterm delivery, cesarean delivery, and maternal mortality compared with women younger than 40 years old (RR 3.18, 95% CI 1.68–5.98). The increased risks for maternal mortality were 42.76 and 11.60 for women older than 50 years and for those older than 45 years, respectively, whereas those for stillbirth were 3.72 and 2.32. The risk of stillbirth and cesarean delivery was significantly higher in women >45 years compared with those aged 40–45 years, and in those aged >50 years compared with those aged 45–50 years. The risk of maternal mortality was significantly higher in women aged >50 years compared with those aged 40–45 (RR 60.40, 95% CI 13.28–274.74). Conclusion The risk of stillbirth, cesarean delivery, and maternal mortality increases with advancing maternal age. The risk ratios for maternal mortality were 3.18, 11.60, and 42.76 in women older than 40, older than 45, and older than 50 years, respectively. These data should be used when women with advanced maternal age are counseled regarding their risk in pregnancy. Systematic Review Registration The review was registered with the PROSPERO International Prospective Register of Systematic Reviews (registration No.: CRD42020208788).
