Effect of group versus individual antenatal care on uptake of intermittent prophylactic treatment of malaria in pregnancy and related malaria outcomes in Nigeria and Kenya: analysis of data from a pragmatic cluster randomized trial

Malar J. 2020 Jan 29;19(1):51. doi: 10.1186/s12936-020-3099-x.

Abstract

Background: Every year, malaria in pregnancy contributes to approximately 20% of stillbirths in sub-Saharan Africa and 10,000 maternal deaths globally. Most eligible pregnant women do not receive the minimum three recommended doses of intermittent preventive treatment with Sulfadoxine-pyrimethamine (IPTp-SP). The objective of this analysis was to determine whether women randomized to group antenatal care (G-ANC) versus standard antenatal care (ANC) differed in IPTp uptake and insecticide-treated nets (ITN) use.

Methods: Prospective data were analysed from the G-ANC study, a pragmatic, cluster randomized, controlled trial that investigated the impact of G-ANC on various maternal newborn health-related outcomes. Data on IPTp were collected via record abstraction and difference between study arms in mean number of doses was calculated by t test for each country. Data on ITN use were collected via postpartum interview, and difference between arms calculated using two-sample test for proportions.

Results: Data from 1075 women and 419 women from Nigeria and Kenya, respectively, were analysed: 535 (49.8%) received G-ANC and 540 (50.2%) received individual ANC in Nigeria; 211 (50.4%) received G-ANC and 208 (49.6%) received individual ANC in Kenya. Mean number of IPTp doses received was higher for intervention versus control arm in Nigeria (3.45 versus 2.14, p < 0.001) and Kenya (3.81 versus 2.72, p < 0.001). Reported use of ITN the previous night was similarly high in both arms for mothers in Nigeria and Kenya (over 92%). Reported ITN use for infants was higher in the intervention versus control arm in Nigeria (82.7% versus 75.8%, p = 0.020).

Conclusions: G-ANC may support better IPTp-SP uptake, possibly related to better ANC retention. However, further research is needed to understand impact on ITN use. Trial registration Pan African Clinical Trials Registry, May 2, 2017 (PACTR201706002254227).
