ObjectiveTo estimate the prevalence of antenatal depression in South Asia and to examine variations by country and study characteristics to inform policy, practice and future research.MethodsWe conducted a comprehensive search of 13 databases including international databases and databases covering scientific literature from South Asian countries in addition to Google Scholar and grey sources from 1 January 2007 to 31 May 2018. Studies reporting prevalence estimates of antenatal depression using a validated diagnostic/screening tool were identified, screened, selected and appraised. Primary outcome was proportion (%) of pregnant women identified as having antenatal depression.ResultsThirty-three studies involving 13 087 pregnant women were included in the meta-analysis. Twelve studies were rated as high quality and 21 studies were of moderate quality. Overall pooled prevalence of antenatal depression was 24.3 % (95% Confidence Interval (CI) 19.03 to 30.47). Studies showed a high degree of heterogeneity (I2=97.66%) and evidence of publication bias (p=0.668). Prevalence rates for India (17.74%, 95% CI 11.19 to 26.96) and Sri Lanka (12.95%, 95% CI 8.29 to 19.68) were lower compared with the overall prevalence, whereas prevalence rates for Pakistan (32.2%, 95% CI 23.11 to 42.87) and Nepal (50%, 95% CI 35.64 to 64.36) were higher.ConclusionsWhile robust prevalence studies are sparse in most South Asian countries, available data suggest one in four pregnant women is likely to experience antenatal depression in the region. Findings highlight the need for recognition of the issue in health policy and practice and for resource allocation for capacity building at regional and national levels for prevention, diagnosis and treatment.

Background Human Immunodeficiency Virus (HIV) infection among pregnant women has been associated with a number of adverse maternal and infant outcomes. Nigeria accounts for about 10% of the HIV/AIDS burden worldwide and has the second highest incidence of new HIV infections among women globally. This study estimated the overall prevalence of HIV among pregnant women in Nigeria and examined variations across the geo-political zones of the country. Methods We conducted a systematic review and meta-analysis. A comprehensive search was conducted using eight electronic databases and grey sources for studies published from 1·1·2008 to 31·8·2019. Primary studies reporting prevalence estimates of HIV among pregnant women diagnosed using a diagnostic/ screening test were identified, screened and appraised using a two-stage process. A meta-analysis was conducted with the primary outcome measure as proportion (%) of pregnant women identified as having HIV infection. Results Twenty three eligible studies involving 72,728 pregnant women were included in the meta-analysis. The overall pooled prevalence of HIV among pregnant women was 7·22% (95% CI: 5·64, 9·21). A high degree of heterogeneity (I2=97·2%) and publication bias (p = 0.728) was reported. Prevalence rate for South-East geo-political zone (17·04%, 95% CI: 9·01, 29·86) was higher compared to the overall prevalence. Conclusions Findings imply that 7 out of every 100 pregnant women in Nigeria are likely to have HIV infection. The magnitude of the issue highlight the need for targeted efforts at local, national and international levels towards prevention, diagnosis and treatment. Key messages HIV infection among pregnant women is a major public health issue in Nigeria. Targeted efforts are needed at local, national and international levels towards prevention, diagnosis and treatment.

ObjectiveTo estimate prevalence of HIV infection in Nigeria and to examine variations by geopolitical zones and study characteristics to inform policy, practice and research.MethodsWe conducted a comprehensive search of bibliographic databases including PubMed, CINAHL, PsycINFO, Global Health, Academic Search Elite and Allied and Complementary Medicine Database (AMED) and grey sources for studies published between 1 January 2008 and 31 December 2019. Studies reporting prevalence estimates of HIV among pregnant women in Nigeria using a diagnostic test were included. Primary outcome was proportion (%) of pregnant women living with HIV infection. A review protocol was developed and registered (PROSPERO 2019 CRD42019107037).ResultsTwenty-three studies involving 72 728 pregnant women were included. Ten studies were of high quality and the remaining were of moderate quality. Twenty-one studies used two or more diagnostic tests to identify women living with HIV. Overall pooled prevalence of HIV among pregnant women was 7.22% (95% CI 5.64 to 9.21). Studies showed high degree of heterogeneity (I2=97.2%) and evidence of publication bias (p=0.728). Pooled prevalence for most individual geopolitical zones showed substantial variations compared with overall prevalence. North-Central (6.84%, 95% CI 4.73 to 9.79) and South-West zones (6.27%, 95% CI 4.75 to 8.24) had lower prevalence whereas South-East zone (17.04%, 95% CI 9.01 to 29.86) had higher prevalence.ConclusionsWhile robust national prevalence studies are sparse in Nigeria, our findings suggest 7 in every 100 pregnant women are likely to have HIV infection. These figures are consistent with reported prevalence rates in sub-Saharan African region. WHO has indicated much higher prevalence in Nigeria compared with our findings. This discrepancy could potentially be attributed to varied methodological approaches and regional focus of studies included in our review. The magnitude of the issue highlights the need for targeted efforts from local, national and international stakeholders for prevention, diagnosis, management and treatment.

To estimate the prevalence of antenatal depression in South Asia and to examine variations by country and study characteristics to inform policy, practice and future research. METHODS We conducted a comprehensive search of 13 data bases including international data bases and databases covering scientific literature from South Asian countries in addition to Google Scholar and grey sources from 1•1•2007 to 31•5•2018. Studies reporting prevalence estimates of antenatal depression using a validated diagnostic/ screening tool were identified, screened, selected, and appraised. Primary outcome was proportion (%) of pregnant women identified as having antenatal depression. RESULTS Thirty-three studies involving 13,087 pregnant women were included in the meta-analysis. Twelve studies were rated as of high quality and 21 studies were of moderate quality. Overall pooled prevalence of antenatal depression was 24•57% (95% CI: 19•34, 30•69). Studies showed a high degree of heterogeneity (I 2 =97•55%) and evidence of publication bias (p=0•722). Prevalence rates for India (17•74%, 95% CI: 11•19, 26•96) and Sri Lanka (15•87%, 95% CI: 14•04, 17•88) were lower compared to the overall prevalence whereas prevalence rates for Pakistan (32•2%, 95% CI: 23•11, 42•87) and Nepal (50%, 95% CI: 35•64,64•36) were higher. CONCLUSIONS While robust prevalence studies are sparse in most South Asian countries, available data suggests one in four pregnant women is likely to experience antenatal depression in the region.

Background Antenatal depression carries significant adverse implications for the health and well-being of women, babies and their families. While prevalence of perinatal mental disorders in low-and lower-middle-income countries tends to be higher compared to high-income countries, rates tend to vary widely among countries in certain regions such as South Asia. This study estimated the pooled prevalence of antenatal depression in South Asia and examined variations in individual countries. Methods We conducted a systematic review and meta-analysis. A comprehensive search was conducted on thirteen electronic databases and grey sources for articles published between 1·1·2007 and 31·5·2018 from South Asian countries including Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka. Studies reporting quantitative prevalence estimates of antenatal depression using a validated diagnostic/ screening tool identified, screened and appraised using a two-stage process. A meta-analysis was conducted using the proportion (%) of pregnant women identified as having antenatal depression as the primary outcome. Results Thirty-three studies involving 13,087 pregnant women were included in the meta-analysis. Overall pooled prevalence was 24·57% (95% CI: 19·34, 30·69). Prevalence rates for India (17·74%, 95% CI: 11·19, 26·96) and Sri Lanka (15·87%, 95% CI: 14·04, 17·88) were lower compared to the overall prevalence whereas the rates for Pakistan (32·2%, 95% CI: 23·11, 42·87) and Nepal (50%, 95% CI: 35·64,64·36) were higher. Conclusions While robust prevalence studies are sparse in most South Asian countries, one in four pregnant women is likely to experience antenatal depression in the region. The issue needs to be recognised in health policy and practice for resource allocation and capacity building at regional and national levels for prevention, diagnosis and treatment.
