【Abstract】 Objective To investigate the temporal trends in childbearing age among reproductive-age couples in Yunfu city,Guangdong province, from 2015 to 2023, and to provide evidence for formulating policies to enhance fertility intentions and optimize perinatal health care services. Methods Using delivery data from the Guangdong Provincial Maternal and Child Health Information Platform(2015-2023), this study analyzed the changing trends in childbearing age among reproductive-age couples in Yunfu city.Temporal changes were assessed using three statistical methods: the Mann-Kendall test for monotonic trends, the chi-squared test for trend of proportional shifts, and the general linear model(GLM) for analysis of annual trajectories of childbearing age among these couples. Results After data cleaning and processing, a total of 280 017 reproductive-age couples were included in the analysis. From2015 to 2023, the average maternal age in Yunfu city was 27.98 ± 5.29 years, and the average paternal age was 30.45 ± 5.82 years.Among the participants, 12.04% of mothers were aged 35 years or older, and 7.24% of fathers were aged 40 years or older. The proportion of mothers aged ≥ 35 years showed a year-on-year increase over the nine-year period. Specifically, maternal age rose from26.54 ± 5.04 years in 2015 to 29.75 ± 5.07 years in 2023, while paternal age increased from 29.04 ± 5.58 years to 32.12 ± 5.67 years.The average childbearing age of both parents showed a consistent year-on-year increase. Additionally, primiparous women exhibited a significant upward trend in childbearing age, rising from 24.86 ± 4.50 years in 2015 to 26.94 ± 4.57 years in 2023. Conclusion From2015 to 2023, the childbearing age of reproductive-age couples in Yunfu city increased significantly and consistently, with a year-onyear rise in the proportion of mothers aged ≥ 35 years. It is recommended to advocate for marriage and childbearing at an appropriate age, mitigate the risks associated with advanced maternal age, and promote the long-term balanced development of the population.更多还原
