ObjectiveTo assess the availability and affordability of medicines and routine tests for cardiovascular disease (CVD) and diabetes in the West region of Cameroon, a low-income setting.MethodsA survey was conducted on the availability and cost of twelve routine tests and twenty medicines for CVD and diabetes in eight health districts (four urban and four rural) covering over 60% of the population of the region (1.8 million). We analyzed the percentage of tests and medicines available, the median price against the international reference price (median price ratio) for the medicines, and affordability in terms of the number of days’ wages it would cost the lowest-paid unskilled government worker for initial investigation tests and procurement for one month of treatment.ResultsThe availability of tests varied between 10% for the ECG to 100% for the fasting blood sugar. The average cost for the initial investigation using the minimum tests cost 29.76 days’ wages. The availability of medicines varied from 36.4% to 59.1% in urban and from 9.1% to 50% in rural settings. Only metformin and benzathine-benzylpenicilline had a median price ratio of ≤1.5, with statins being largely unaffordable (at least 30.51 days’ wages). One month of combination treatment for coronary heart disease costs at least 40.87 days’ wages.ConclusionThe investigation and management of patients with medium-to-high cardiovascular risk remains largely unavailable and unaffordable in this setting. An effective non-communicable disease program should lay emphasis on primary prevention, and improve affordable access to essential medicines in public outlets.

Accurate estimates of the prevalence rate of hypertension and determinants in Cameroon are crucial to inform efficient prevention and control policies. The authors carried out a cluster-specific cross-sectional survey in urban areas of the 10 regions of Cameroon to assess the prevalence and risk factors of hypertension in Cameroonian adults using the WHO STEPwise approach to Surveillance (STEPS). Sociodemographic data were collected and blood pressure and glycemia were measured using standardized methods. Participants were adults of both sexes aged 16 years or older. A total of 15,470 participants were surveyed. The age-standardized prevalence rate of hypertension was 29.7%. The awareness rate was 14.1%. Independent correlates of hypertension included higher age, male sex, obesity, hyperglycemia, and living in the Savannah zone. The prevalence of hypertension is high in urban areas of Cameroon, with very low awareness. Prevention and control strategies should emphasize on improvement and vulgarization of population opportunistic screening and education.

BackgroundEpidemiological data on hepatitis B virus (HBV) infection among pregnant women in Cameroon are very scarce, especially in the rural milieu. The purpose of this study was to determine the prevalence and factors associated with HBV infection, and the infectivity of rural pregnant women in the Far North Region of Cameroon.MethodsA cross-sectional study was conducted in three rural health facilities of the Guidiguis health district between December 2013 and March 2014. We consecutively recruited 325 pregnant women attending antenatal consultations. A pretested questionnaire was used to collect socio-demographic data and factors associated with HBV infection. The presence of hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg) and human immunodeficiency virus (HIV) were determined using commercial test strips. Regression analyses were used to assess correlates of HBV infection.ResultsThe mean age was 24.4 (SD5.6) years. Most women were married (97.2%) and housewives (96.4%), with less than secondary education level (80%). Only 4 women (1.2%) had been vaccinated against HBV. Thirty-three women (10.2%) were HBsAg-positive, of whom 4 (12.1%) were positive to HBeAg. The prevalence of HIV infection was 2.5% (8/325). Overall, 5 (1.5%) women were co-infected with HIV and HBV. Independent correlates of HBV infection included history of blood transfusion (adjusted odd ratio 12.59, 95% CI 1.46-108.89; p = 0.021) and concurrent infection by HIV (adjusted odd ratio 22.53, 95% CI 4.76-106.71; p < 0.0001).ConclusionThe prevalence of HBV infection among pregnant women in this rural milieu is high. History of blood transfusion and HIV infection are highly associated with HBV infection. The relative low rate of women positive to both HBsAg and HBeAg suggests that perinatal transmission of HBV might not be the prevailing mode of HBV transmission in this area.

Hypertensive disorders of pregnancy (HDP) are a major contributor to maternal and perinatal morbidity and mortality, especially in resource‐limited settings. Little is known about the magnitude of HDP in Africa. We conducted the first systematic review and meta‐analysis to summarize available data on the prevalence of HDP in Africa. We did a comprehensive literature search to identify review paper published from January 1, 1996, to September 30, 2017, and searched the reference list of retrieved review paper. We used a random‐effects model to estimate the overall and type‐specific prevalence of HDP in Africa. We included 82 studies published between 1997 and 2017 reporting data on a pooled sample of 854 304 women during pregnancy or puerperium. Most studies were hospital‐based, conducted in urban settings across 24 countries. In this population, the overall prevalence of HDP was 100.4‰ (95% CI: 81.4‐121.2). The prevalence was 49.8‰ (95% CI: 32.3‐70.7) for gestational hypertension, 14.7‰ (95% CI: 11.6‐18.2) for chronic hypertension, 9.2‰ (95% CI: 4.2‐16.0) for superimposed preeclampsia, 44.0‰ (95% CI: 36.7‐52.0) for preeclampsia, 22.1‰ (95% CI: 14.8‐30.8) for severe preeclampsia, 14.7‰ (95% CI: 8.1‐23.2) for eclampsia and 2.2‰ (95% CI: 1.2‐3.4) for HELLP syndrome. Prevalence of HDP was significantly higher in Central and Western Africa; there was a consistent tendency of increasing HDP prevalence with income at the country level. In conclusion, the burden of HDP in Africa is high, with about one in 10 pregnancies affected. The higher rate of severe forms of HDP that are associated with significant maternal and perinatal mortality is a major concern in the region.
