BackgroundPrevalence of child stunting in the Democratic Republic of Congo (DRC) is among the highest in the world. There is a need to systematically investigate how stunting operates at different levels of determination and identify major factors contributing to the development of stunting. The aim of this study was to look for key determinants of stunting in the DRC.MethodsThis study used data from the DRC Demographic Health Survey 2013–14 which included anthropometric measurement for 9030 under 5 year children. Height-for-Age Z score was calculated and classified according to the WHO guideline. The association between stunting and bio-demographic characteristics was assessed using logistic regression.ResultsPrevalence of stunting was much higher in boys than girls. There was a significant rural urban gap in the prevalence of stunting with rural areas having a larger proportion of children living with stunting than urban.Male children, older than 6 months, preceding birth interval less than 24 months, being from lower wealth quintiles had the highest odds of stunting. Several provinces had in particular high odds of stunting. Early initiation of breastfeeding, mother’s age more than 20 years at the time of delivery had lower odds of stunting. The taller the mother the less likely the child was to be stunted. Similarly, mother’s BMI, access to safe water, access to hygienic toilet, mother’s education were found negatively correlated with child stunting in the bivariate logistic regression, but they lost statistical significance in multivariate analysis together with numbers of children in the family and place of residence.ConclusionsChild stunting is widespread in the DRC and increasing prevalence is worrisome. This study has identified modifiable factors determining high prevalence of stunting in the DRC. Policy implementation should in particular target provinces with high prevalence of stunting and address modifiable determinants such as reducing socioeconomic disparity. Nutrition promotion intervention, including early initiation of breastfeeding should be an immediate priority.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-017-4621-0) contains supplementary material, which is available to authorized users.

Understanding modifiable determinants of full immunization of children provide a valuable contribution to immunization programs and help reduce disease, disability, and death. This study is aimed to assess the individual and community-level determinants of full immunization coverage among children in the Democratic Republic of Congo. This study used data from the Demographic and Health Survey 2013–14 from the Democratic Republic of Congo. Data regarding total 3,366 children between 12 and 23 months of age were used in this study. Children who were immunized with one dose of BCG, three doses of polio, three doses of DPT, and a dose of measles vaccine was considered fully immunized. Descriptive statistics were calculated for the prevalence and distribution of full immunization coverage. Two-level multilevel logistic regression analysis, with individual-level (level 1) characteristics nested within community-level (level 2) characteristics, was used to assess the individual- and community-level determinants of full immunization coverage. This study found that about 45.3% [95%CI: 42.02, 48.52] of children aged 12–23 months were fully immunized in the DRC. The results confirmed immunization coverage varied and ranged between 5.8% in Mongala province to 70.6% in Nord-Kivu province. Results from multilevel analysis revealed that, four Antenatal Care (ANC) visits [AOR: 1.64; 95%CI: 1.23, 2.18], institutional delivery [AOR: 2.37; 95%CI: 1.52, 3.72], and Postnatal Care (PNC) service utilization [AOR: 1.43; 95%CI: 1.04, 1.95] were statistically significantly associated with the full immunization coverage. Similarly, children of mothers with secondary or higher education [AOR: 1.32; 95%CI: 1.00, 1.81] and from the richest wealth quintile [AOR: 1.96; 95%CI: 1.18, 3.27] had significantly higher odds of being fully immunized compared to their counterparts whose mothers were relatively poorer and less educated. Among the community-level characteristics, residents of the community with a higher rate of institutional delivery [AOR: 2.36; 95%CI: 1.59, 3.51] were found to be positively associated with the full immunization coverage. Also, the random effect result found about 35% of the variation in immunization coverage among the communities was attributed to community-level factors.The Democratic Republic of Congo has a noteworthy gap in full immunization coverage. Modifiable factors–particularly health service utilization including four ANC visits, institutional delivery, and postnatal visits–had a strong positive effect on full immunization coverage. The study underlines the importance of promoting immunization programs tailored to the poor and women with little education.

The risk perception bias associated with non-paying partners, time as a commercial sex worker and age should be taken into account when planning interventions targeting CSW. Access to condoms and VCT should be improved because they are likely to impact on behaviour.

BackgroundHypertension remains a public health challenge worldwide. In the Democratic Republic of Congo, its prevalence has increased in the past three decades. Higher prevalence of poor blood pressure control and an increasing number of reported cases of complications due to hypertension have also been observed. It is well established that non-adherence to antihypertensive medication contributes to poor control of blood pressure. The aim of this study is to measure non-adherence to antihypertensive medication and to identify its predictors.MethodsA cross-sectional study was conducted at Kinshasa Primary Health-care network facilities from October to November 2013. A total of 395 hypertensive patients were included in the study. A structured interview was used to collect data. Adherence to medication was assessed using the Morisky Medication Scale. Covariates were defined according to the framework of the World Health Organization. Logistic regression was used to identify predictors of non-adherence.ResultsA total of 395 patients participated in this study. The prevalence of non-adherence to antihypertensive medication and blood pressure control was 54.2 % (95 % CI 47.3–61.8) and 15.6 % (95 % CI 12.1–20.0), respectively. Poor knowledge of complications of hypertension (OR = 2.4; 95 % CI 1.4–4.4), unavailability of antihypertensive drugs in the healthcare facilities (OR = 2.8; 95 % CI 1.4–5.5), lack of hypertensive patients education in the healthcare facilities (OR = 1.7; 95 % CI 1.1–2.7), prior experience of medication side effects (OR = 2.2; 95 % CI 1.4–3.3), uncontrolled blood pressure (OR = 2.0; 95 % CI 1.1–3.9), and taking non-prescribed medications (OR = 2.2; 95 % CI 1.2–3.8) were associated with non-adherence to antihypertensive medication.ConclusionThis study identified predictors of non-adherence to antihypertensive medication. All predictors identified were modifiable. Interventional studies targeting these predictors for improving adherence are needed.

Context: Homeless children are at risk of getting many diseases, including sexually transmitted infections (STI). The number of street children is on the rise in the Democratic Republic of Congo (DRC), while very little is known about their health problems. Objectives: To determine knowledge of HIV (transmission and prevention means), sexual activity, exposure to HIV-prevention services, and to identify correlates of risky sexual behaviour (not having used a condom at first or last sexual encounter and/or having multiple sexual partners over a 12-month period) among street children in Kinshasa. Results: At the time of the survey, most participants (85.8%, 95% CI = 83.5-88.1) were sexually experienced and 55.8% had their first sexual intercourse when they were already living on the streets. The median age at first sexual activity was 14.3 years for males and 13.5 years for females. Compared to males (median number of sexual partners = 1), females tended to be more involved with multiple sexual partners (median = 12). Condoms were used less at the fist sexual encounter (20.2%; 95% CI =17.3-23.1) and the pattern of condom use depended on the type of sexual partners (61.1% at last sexual encounter with a paid/paying partner and 23.1% at last sexual encounter with a non-paid/non-paying partner). In males, sleeping in a NGO-provided night shelter (OR= 0.47; 95% CI = 0.27-0.79), and having had the first sexual intercourse while living on the streets (OR = 0.55; 95% CI = 0.35-0.88) were protective of risky sexual behaviour, while a history of drug use (OR = 3.00; 95% CI = 1.46-6.18), and being aged 20 to 24 years (OR = 1.59; 95% 1.00-2.55) increased the likelihood of displaying risky sexual behaviour. In females, not knowing where to get a condom (OR = 0.04; 95% CI = 0.005-0.29), having started sexual activity when living on the streets (OR = 0.10; 95% CI = 0.01-0.73) and not having an income-generating activity (OR = 0.09; 95% CI = 0.01-0.44) were protective of risky sexual behaviour. Conclusion: Street children need to be regarded as a high-risk group for acquiring HIV. The potential benefit of providing homeless youth with night-shelters should be explored more since this could be an opportunity to integrate risk-reduction programmes that take into account all problematic behaviors such as risky sexual behaviour and drug use.
