“…Other studies reported neither reasons for CS nor proportions of planned versus emergency CS. The included studies adjusted for maternal age – a known confounder, since the incidence of elective CS increases significantly with increasing maternal age – are presented in Table S1 . A large national register cohort from Canada showed a three‐fold increased risk [AOR, 3.1 (95% CI, 3.0–3.3)] in overall severe maternal morbidity including haemorrhage requiring hysterectomy, cardiac arrest, venous thromboembolism and major infection in almost 47 000 planned low‐risk CS versus more than 2.3 million planned low‐risk vaginal deliveries .…”

“…Women with medical conditions significantly associated with elective caesarean section were excluded (37% of the total primiparous population and 31% of primiparas with gestational age ≥37 weeks, increasing from 29% among women aged <20 years to 45% in those aged ≥40 years). 19 In the remaining low-risk population the associations between maternal age and mode of delivery were explored using descriptive statistics, contingency tables, chi-square tests, Student's t-tests, and one-way between-groups analysis of variance (ANOVA), with a post-hoc test with Bonferroni correction. Similar procedures were performed to evaluate the in-labour indications, sociodemographic factors, and other contributing factors for emergency caesarean section.…”

Objective To study the association between maternal age and emergency operative delivery. The roles of in-labour indications, and birthweight ≥ 4000 g, gestational age ≥ 42 weeks, induction of labour, and epidural use, according to maternal age were explored.Design Population-based study.Setting Medical Birth Registry of Norway and Statistics Norway.Population We studied 169 583 low-risk primiparous mothers with singleton, cephalic labours, at ≥37 weeks of gestation, from 1999 to 2009. MethodsThe associations between maternal age and mode of delivery were analysed using multinomial regression analyses, adjusting for sociodemographic factors.Main outcome measures Emergency caesarean section and operative vaginal delivery.Results Of women aged ≥40 years, 22% had emergency caesarean sections and 24% had operative vaginal deliveries, giving adjusted relative risk ratios (RRRs) of 6.60 (95% confidence interval, 95% CI 5.53-7.87) and 3.30 (95% CI 2.79-3.90), respectively, when compared with women aged 20-24 years. Adjustments for sociodemographic factors only slightly changed the estimates. Dystocia was the main indication, followed by fetal distress. All of the listed factors increased the level of emergency operative deliveries, mainly because of an increase in dystocia. The increase in risk for emergency caesarean section by all factors, and for operative vaginal deliveries by epidural, were greater in older than in younger women, but were significant for epidural only.Conclusions We found a close association between maternal age and emergency operative delivery in low-risk primiparas. Contributory factors increased the risk for both emergency operative delivery and epidural more in older than in younger women.

“…A previous meta‐analysis suggested a strong association between caesarean delivery and increased offspring BMI (Darmasseelane, Hyde, Santhakumaran, Gale, & Modi, ), and evidence shows that the rate of elective (i.e., not medically indicated) caesarean section increases with advancing maternal age (Herstad et al, ). We also observed a much higher proportion of children delivered by caesarean section in the group with maternal age at birth of ≥31 years.…”

Objectives: Although delayed parenthood has been linked to various adverse health outcomes in offspring, little attention has been given to the relationship between an increased parental age at childbirth and fat distribution in offspring. We aimed to determine the relationship between parental age at childbirth and body fat partitioning in Chinese children. Methods: A total of 463 children (mean age, 8 years; 43% female) were recruited. Dual-energy X-ray absorptiometry was used to determine the fat mass (FM) and percentage of fat mass (%FM) in various areas of the body. Weight and height were measured. The body mass index (BMI) and fat mass index (FMI) were calculated. A questionnaire was used to collect information about parental variables and other confounders. Results: Multiple linear regression analyses suggested that for each additional year of maternal age at delivery, the BMI, FMI, and FM at whole-body, trunk, android, gynoid, and appendicular region increased by 0.115 kg/m 2 , 0.076 kg/m 2 ; 128.4 g, 57.71 g, 10.96 g, 25.07 g, and 67.88 g, respectively, after adjusting for covariates (P = .002-.017). In the analysis of covariance, children of mothers aged ≥31 years exhibited higher BMI, FMI, total-body and segmental FM, compared to those of mothers aged ≤25 years (P-trend = 0.002-0.017). Similar tendencies were also observed for the %FM (P-trend = 0.002-0.017). However, there was no significant relationship between paternal age at childbirth and any of the body fat measures in children.Conclusions: An increasing maternal age at childbirth was associated with increased body fat accumulation in offspring, whereas paternal age at childbirth appeared to have no such association.
