Objective The aim of this study was to assess the effects of COVID-19 on antenatal care (ANC) utilisation in Kenya, including women’s reports of COVID-related barriers to ANC and correlates at the individual and household levels. Design Cross-sectional study. Setting Six public and private health facilities and associated catchment areas in Nairobi and Kiambu Counties in Kenya. Participants Data were collected from 1729 women, including 1189 women who delivered in healthcare facilities before the COVID-19 pandemic (from September 2019-January 2020) and 540 women who delivered during the pandemic (from July through November 2020). Women who delivered during COVID-19 were sampled from the same catchment areas as the original sample of women who delivered before to compare ANC utilisation. Primary and secondary outcome measures Timing of ANC initiation, number of ANC visits and adequate ANC utilisation were primary outcome measures. Among only women who delivered during COVID-19 only, we explored women’s reports of the pandemic having affected their ability to access or attend ANC as a secondary outcome of interest. Results Women who delivered during COVID-19 had significantly higher odds of delayed ANC initiation (ie, beginning ANC during the second vs first trimester) than women who delivered before (aOR 1.72, 95% CI 1.24 to 2.37), although no significant differences were detected in the odds of attending 4-7 or ≥8 ANC visits versus <4 ANC visits, respectively (aOR 1.12, 95% CI 0.86 to 1.44 and aOR 1.46, 95% CI 0.74 to 2.86). Nearly half (n=255/540; 47%) of women who delivered during COVID-19 reported that the pandemic affected their ability to access ANC. Conclusions Strategies are needed to mitigate disruptions to ANC among pregnant women during pandemics and other public health, environmental, or political emergencies.
This study uses non-representative, cross-sectional data from two samples of participants: (1) women recruited within 7 days of delivery while admitted/on discharge at one of six participating facilities (three public hospitals, two private hospitals and one health centre) in Nairobi and Kiambu Counties from September 2019 through January 2020 (ie, prior to the onset of the COVID-19 pandemic; n=1197)17 and (2) women residing in catchment areas of these same six participating facilities, who delivered since pandemic-related restrictions were mandated in Kenya (ie, from March 16, 2020; n=1135).18 The latter sample was recruited with the specific intent of understanding the effects of COVID-19 on maternal and newborn health by leveraging the existing data among the sample of postpartum women surveyed just prior to the start of the pandemic. Additional information about both samples, including eligibility and recruitment procedures, can be found in previous publications.17 18 In short, eligible participants in both samples were those aged 15–49 years who had delivered a singleton birth within the specified timeframe and had access to a functional phone to allow for follow-up. Vaginal delivery was an additional eligibility criterion among the sample of women who delivered before COVID-19.17 The sample of women who delivered before COVID-19 were conveniently sampled in partnership with facility staff working in the postnatal wards. All women in the postnatal ward during working hours who were still admitted or at discharge were approached to learn about the study and determine interest and eligibility; among the 1357 women approached, a total of 1197 consented and enrolled (88.2%) in this previous study which assessed women’s receipt of person-centred maternity care and its association with maternal and newborn health outcomes. The sample of women who delivered during COVID-19 was conveniently sampled through engagement with community health volunteers and local village leaders and completed the survey in November 2020; among the 1182 women contacted by phone, a total of 1135 consented and enrolled in the study (96.0%).18 An experienced team of nine female enumerators participated in a 3-day, virtual training on the study protocol and survey tools. This was followed by a 1 day piloting exercise among 30 women for the enumerators to practice the study consent, assess and refine the survey flow and test study logistics and quality check procedures. Participants were contacted by phone for both the consent and a one-time, 30-min survey, though participants had the option for scheduling a separate time for the survey to be administered. For those unable to be reached, a total of nine attempts were made across different days and times. Participants received the equivalent of approximately US$1.00 (US dollar) of airtime as a token of appreciation. The primary outcomes of interest were: timing of ANC initiation, total number of ANC visits and adequate ANC utilisation. Items on the number and timing of antenatal visits were adapted from the 2014 Kenya Demographic and Health Survey.6 The timing of ANC initiation was measured by asking women approximately how many months or weeks pregnant they were when they attended their first ANC appointment. A categorical variable was then created to capture if ANC began in the first, second or third trimester. The total number of ANC visits was a categorical variable capturing whether women attended <4, 4–7 or ≥8 visits. Finally, information on the timing of ANC initiation and the total number of ANC visits was used to create a binary variable capturing whether women achieved adequate ANC utilisation, defined as initiating ANC during the first trimester and attending at least four visits (1=yes, 0=no). Among women who delivered during COVID-19 only, we explored whether women reported the pandemic to have affected their ability to access or attend ANC (1=yes, 0=no) as a secondary outcome of interest. We also included information on individual and household sociodemographic characteristics, including age, marital status, educational attainment, employment status, self-rated health and parity. Women who delivered during COVID-19 were asked about household food insecurity using the Household Food Insecurity Access Scale,19 and assigned a score (ranging 0–6) reflecting how many household food insecurity indicators were endorsed (Cronbach’s α=0.80). Women were also asked how the pandemic affected their ability to access or attend ANC. The analytic sample was first restricted to those with complete information on ANC measures (n=8/1197 missing among women who delivered before COVID-19 and n=13/1135 missing among women who delivered during COVID-19). To ensure that a substantial portion of the gestational period occurred during the pandemic (as opposed to a significant period of gestation occurring prior to the start of the COVID-19 pandemic and strictest lockdown measures) and would thus be vulnerable to potential COVID-related effects to ANC utilisation, the sample of women who delivered during COVID-19 was further restricted to those who delivered from July 2020 through the end of the study period in November 2020. This resulted in an additional 582 women who delivered from March 16 through June 2020 being excluded and a final analytic sample of 1189 women who delivered before and 540 women who delivered during COVID-19. Data were analysed using descriptive, bivariate and multivariable statistics using StataSE V.15. Pearson χ2 tests were used to examine differences in the distribution of demographic characteristics and measures of ANC utilisation across study samples. Multivariable logistic regression models were used to assess the relationship between study sample and timing of ANC initiation, number of ANC visits and adequate ANC utilisation, respectively, after controlling for individual level characteristics. Sensitivity analyses were conducted to examine the robustness of the models when restricting the sample of women who delivered during COVID-19 to those who delivered from August through November 2020 (n=372) and then September through November 2020 (n=234), respectively. These groups represent those whose gestational periods would have most significantly overlapped with the pandemic (ie, most or all of their pregnancy occurred after 16 March 2020). A multivariable logistic regression model was also used to assess factors associated with women reporting COVID-19 to affect accessing or attending ANC. The Institutional Review Boards at the University of California, Los Angeles (UCLA) and Kenya Medical Research Institute (KEMRI) approved all study procedures and all women provided verbal consent. Patients and members of the public were not involved in the design of this research; however, members of the public, including community health volunteers and local village leaders in study catchment areas, were involved in the recruitment of women who had delivered during the pandemic. These members of the public were also provided a policy brief of key study findings to disseminate to stakeholders within their communities.
