# The prevalence of contraceptive use among postpartum women and its associated factors during the early phase of COVID-19 outbreak: a time series study

## TL;DR

This study found that postpartum check-ups are important for new mothers to start using effective birth control, even during the early stages of the COVID-19 pandemic.

## Contribution

The study highlights the role of postpartum check-ups in promoting long-acting reversible contraception during a health crisis.

## Key findings

- The proportion of women initiating non-permanent modern contraceptives was similar during the pandemic and pre-pandemic periods.
- Fewer women chose long-acting reversible contraception (LARC) during the pandemic compared to before.
- Postpartum check-ups were independently associated with higher odds of LARC initiation.

## Abstract

Unintended pregnancies can adversely affect maternal health, preventable through timely postpartum contraception. During the COVID-19 pandemic, family planning services were constrained by policies that curtailed outpatient visits. We investigated the prevalence of postpartum contraceptive initiation at King Chulalongkorn Memorial Hospital (KCMH) during January to June 2020, comparing with the same period in 2019, and identified factors associated with such initiation.

We reviewed the medical records of 4506 postpartum women who delivered at KCMH during the study period. Logistic regression was conducted to test the association between early COVID-19 phase deliveries and post-partum long acting reversible contraception (LARC) initiation including copper intrauterine devices, levonorgestrel intrauterine systems, contraceptive implants, and progestogen-only injectable contraceptives.

A total of 3765 women (83.6%), of whom 1821 delivered during the pandemic and 1944 during the historical cohort period, were included in this study. The proportion of women who initiated non-permanent modern contraceptives at six weeks postpartum was comparable between the COVID-19 (73.4%) and historical cohort (75.3%) (p = 0.27) periods. The proportion of women who initiated LARC at six weeks postpartumwas comparable between the historical cohort period (22.5%) and the COVID-19 (19.7%) (p = 0.05) period. Accessing a six-week postpartum check-up was independently associated with LARC initiation, of which the adjusted odds ratio (OR) (95% confidence interval) was 3.01 (2.26 to 4.02).

Our findings demonstrated that accessing postpartum care significantly associate with the use of LARC. The data suggest the strong influence of postpartum check-ups in facilitating the adoption of effective contraception, emphasizing the need for accessible postpartum care to sustain maternal health during health crises.

In this study, we looked at how often new mothers used birth control methods after giving birth during the COVID-19 pandemic in Thailand. We also wanted to find the factors that influenced their decision to use birth control. We reviewed the medical records of 4,506 women who had recently given birth at King Chulalongkorn Memorial Hospital. Out of these, 3,765 women were included in the study. Some gave birth during the pandemic, and others gave birth before the pandemic. We found that a similar number of women started using birth control about six weeks after giving birth, whether it was during the pandemic or before it. However, slightly fewer women chose very effective methods of birth control during the pandemic compared to before it. One important factor we found was that women who went for a check-up six weeks after giving birth were more likely to use highly effective birth control. This means that getting regular check-ups after childbirth can help women make better choices about birth control. In summary, our study showed that receiving postpartum care is closely linked to using LARC. This underlines how important it is for new mothers to have their check-ups after giving birth, to help them start using effective birth control if they choose.
