Abstract

Objective

To explore the association between menstrual cycle characteristics and time to pregnancy (TTP) among nurses.

Methods

A retrospective cohort study was conducted between 2019 and 2023. Based on the total number of nurses at the Health Institute of the State of Mexico, the sample size was calculated, resulting in 378 nurses. The study included 600 participants who agreed to participate and had their first pregnancy within the last 14 years. The variables of interest were collected through a questionnaire, and the data analysis employed a discrete-time analogue of the Cox proportional hazards model.

Results

A significant association was identified between increased TTP and the age at menarche (ORF = 0.80; 95% CI: 0.70-0.92), menstrual irregularity (ORF = 0.54; 95% CI: 0.35-0.85), cycles until menstruation became regular (ORF = 0.43; 95% CI: 0.36-0.52), and moderate (ORF = 0.55; 95% CI: 0.35-0.86) or heavy menstrual bleeding (ORF = 0.26; 95% CI: 0.35-0.70).

Conclusions

Menstrual cycle characteristics are significantly associated with TTP among nursing professionals. These findings highlight the importance of monitoring and understanding menstrual patterns to improve fertility planning and management in this professional group. However, methodological limitations of the retrospective design, such as recall bias, should be considered.

月经模式对墨西哥护士怀孕时间的影响：回顾性队列

目的探讨护士月经周期特征与妊娠时间（TTP）的关系。方法2019 - 2023年进行回顾性队列研究。根据墨西哥州卫生研究所的护士总数，计算了样本量，结果是378名护士。该研究包括600名同意参与且在过去14年内首次怀孕的参与者。通过问卷调查收集感兴趣的变量，数据分析采用Cox比例风险模型的离散时间模拟。结果TTP升高与月经初潮年龄（ORF = 0.80, 95% CI: 0.70-0.92）、月经不规律（ORF = 0.54, 95% CI: 0.35-0.85）、月经周期恢复正常（ORF = 0.43, 95% CI: 0.36-0.52）、中度（ORF = 0.55, 95% CI: 0.35-0.86）或重度月经出血（ORF = 0.26, 95% CI: 0.35-0.70）有显著相关性。结论护理人员月经周期特征与TTP有显著相关性。这些发现强调了监测和了解月经模式对提高该专业群体的生育计划和管理的重要性。然而，应该考虑到回顾性设计的方法学局限性，如回忆偏倚。
