Purpose
This study aims to better understand advanced maternal age (AMA) and its impact on maternal and perinatal health by investigating the prevalence, sociodemographic profiles and adverse pregnancy outcomes of AMA in Abu Dhabi, UAE.

Design/methodology/approach
This study is a part of a large multicenter cross-sectional study. The project aimed to improve maternal and early child health in Abu Dhabi, UAE. It was conducted at seven healthcare centers located in the urban, suburban and rural areas of Abu Dhabi. The project’s data included all mothers (i.e. Emirati and non-Emirati mothers) who came to the centers looking for healthcare follow-up.

Findings
From the total of 1,710 enrolled mothers with complete data, 379 were with AMA, having a prevalence of 22.2% (95% confidence interval [CI] = 20.2, 24.2). Among 379 advanced maternal age (AMA) mothers, 328(84.5%), and 51(15.5) mothers were between 35 and 39 years, and =40 years, respectively. The mean (SD) of maternal age was 30.0(5.2) years. No significant association was found between AMA, and parent’s education, family income, child gender, preterm birth and low birth weight. In multivariable logistic regression analysis, factors significantly associated with AMA were higher parity (adjusted odd ratio [AOR] = 2.24, 95%CI = 2.00, 2.50), p-value < 0.001, non-Arab mothers (AOR = 2.44, 95%CI = 1.83, 3.24), p-value < 0.001, maternal employment (AOR = 1.37, 95%CI = 1.05, 1.77), p-value = 0.019, and cesarean delivery (AOR = 2.44, 95% CI = 1.83, 3.24), p-value = 0.011, pre-pregnancy maternal overweight (AOR = 1.49, 95%CI = 1.12, 1.98), p-value = 0,006, and pre-pregnancy maternal obesity (AOR = 2.15, 95%CI = 1.35, 3.44), p-value = 0.001.

Research limitations/implications
First, unlike other studies, not all obstetrical outcomes (e.g. maternal and perinatal mortality and morbidity) were included as the current study data were part of a large project, and such limitations are expected; second, only quantitative method was used in the present study, it is clear from the literature AMA is a dilemma. Therefore, a qualitative study and mixed methods (both quantitative and qualitative) will provide a better explanation for such an understudied topic. Therefore, further research is recommended to overcome the abovementioned limitations aiming to explore the complexity of AMA, including studying its social determinants. Furthermore, it is worth emphasizing that future research involves more concerned parties, including health, culture and planning authorities, to better understand AMA issues.

Originality/value
The study provided valuable information regarding AMA issues in the UAE. Such information is of paramount importance to all involved parties, including policymakers, to take action regarding improving the health of mothers with advanced ages. Specific actions can be taken through thorough counseling of all expectant mothers with advanced ages before pregnancy, throughout pregnancy and delivery and beyond, by dealing with existing medical conditions and highlighting possible risks of AMA on pregnancy outcomes and how to overcome them in advance. In addition, further research is recommended to explore the social determinants of AMA.
