Previous studies have suggested that emergent events may affect pregnancy planning decisions. However, few have investigated the effect of factors related to the COVID-19 pandemic on pregnancy planning, measured by attempting conception, and how attempting conception status may differ by individual-level factors, such as social status or educational level.
This study aimed to examine the effects of factors related to the COVID-19 pandemic, until March 2021, on attempting conception status and to assess the effect measure modification by educational level and subjective social status.
We conducted a longitudinal analysis within a subgroup of 21,616 participants in the Apple Women's Health Study who enrolled from November 2019 to March 2021, who met the inclusion criteria, and who responded to the monthly status menstrual update question on attempting conception status (yes or no). Participants reporting hysterectomy, pregnancy, lactation, or menopause were excluded. We used generalized estimating equation methodology to fit logistic regression models that estimate odds ratios and 95% confidence intervals for the association between the proportion of participants attempting conception and the month of response (compared with a prepandemic reference month of February 2020) while accounting for longitudinal correlation and adjusting for age, race and ethnicity, and marital status. We stratified the analysis by social status and educational level.
We observed a trend of reduced odds of attempting conception, with an 18% reduction in the odds of attempting conception in August 2020 and October 2020 compared with the prepandemic month of February 2020 (August odds ratio: 0.82 [95% confidence interval, 0.70-0.97]; October odds ratio: 0.82 [95% confidence interval, 0.69-0.97). The participants with lower educational level (no college education) experienced a sustained reduction in the odds of attempting to conceive from June 2020 to March 2021 compared with February 2020, with up to a 24% reduction in the odds of attempting to conceive in October 2020 (odds ratio, 0.76; 95% confidence interval, 0.59-0.96). Among participants that were college educated, we observed an initial reduction in the odds of attempting to conceive starting in July 2020 (odds ratio 0.73; 95% confidence interval, 0.54-0.99) that returned near prepandemic odds. Moreover, we observed a reduction in the odds of attempting to conceive among those with low subjective social status, with a decline in the odds of attempting to conceive beginning in July 2020 (odds ratio, 0.83; 95% confidence interval, 0.63-1.10) and continuing until March 2021 (odds ratio, 0.79; 95% confidence interval, 0.59-1.06), with the greatest reduction in odds in October 2020 (odds ratio, 0.67; 95% confidence interval, 0.50-0.91).
Among women in the Apple Women's Health Study cohort, our findings suggested a reduction in the odds of attempting to conceive during the COVID-19 pandemic, until March 2021, particularly among women of lower educational level and lower perceived social status.
先前的研究表明突发情况可能会影响妊娠计划决策。然而,很少有研究调查与 COVID-19 大流行相关的因素对妊娠计划的影响,这些因素通过尝试受孕来衡量,以及尝试受孕的状态如何因个体因素(如社会地位或教育水平)而有所不同。
本研究旨在研究截至 2021 年 3 月与 COVID-19 大流行相关的因素对尝试受孕状态的影响,并评估教育水平和主观社会地位对测量效果的影响。
我们对 2019 年 11 月至 2021 年 3 月期间参加 Apple 女性健康研究的 21616 名符合纳入标准且对尝试受孕状态(是或否)进行每月月经更新问题的回答的参与者进行了纵向分析。排除了接受子宫切除术、怀孕、哺乳或绝经的参与者。我们使用广义估计方程方法拟合逻辑回归模型,估计比例尝试受孕的参与者与反应月份(与 2020 年 2 月大流行前参考月份相比)之间的关联的优势比和 95%置信区间,同时考虑到纵向相关性,并调整了年龄、种族和民族以及婚姻状况。我们按社会地位和教育水平对分析进行分层。
我们观察到尝试受孕的几率呈下降趋势,与 2020 年 8 月和 10 月相比,尝试受孕的几率分别下降了 18%和 18%,与大流行前的 2020 年 2 月相比(8 月的优势比:0.82 [95%置信区间,0.70-0.97];10 月的优势比:0.82 [95%置信区间,0.69-0.97])。受教育程度较低(没有大学学历)的参与者从 2020 年 6 月到 2021 年 3 月尝试受孕的几率持续下降,与 2020 年 2 月相比,尝试受孕的几率最多下降了 24%,2020 年 10 月的受孕几率(优势比,0.76;95%置信区间,0.59-0.96)。在接受过大学教育的参与者中,我们观察到从 2020 年 7 月开始尝试受孕的几率最初下降(优势比 0.73;95%置信区间,0.54-0.99),随后接近大流行前的几率。此外,我们观察到低主观社会地位者尝试受孕的几率降低,2020 年 7 月开始受孕几率下降(优势比,0.83;95%置信区间,0.63-1.10),并持续到 2021 年 3 月(优势比,0.79;95%置信区间,0.59-1.06),2020 年 10 月的受孕几率降幅最大(优势比,0.67;95%置信区间,0.50-0.91)。
在 Apple 女性健康研究队列的女性中,我们的研究结果表明,在 2021 年 3 月之前,COVID-19 大流行期间尝试受孕的几率下降,特别是在教育程度较低和社会地位较低的女性中。
