Comparative analysis of the health status of the population in six health zones in South Kivu: a cross-sectional population study using the WHODAS

Abstract

Background The eastern Democratic Republic of Congo (DRC) has experienced decades-long armed conflicts which have had a negative impact on population’s health. Most research in public health explores measures that focus on a specific health problem rather than overall population health status. The aim of this study was to assess the health status of the population and its predictors in conflict settings of South Kivu province, using the World Health Organization Disability Assessment Schedule (WHODAS). Methods Between May and June 2019, we conducted a community-based cross-sectional survey among 1440 adults in six health zones (HZ), classified according to their level of armed conflict intensity and chronicity in four types (accessible and stable, remote and stable, intermediate and unstable). The data were collected by a questionnaire including socio-demographic data and the WHODAS 2.0 tool with 12 items. The main variable of the study was the WHODAS summary score measuring individual’s health status and synthesize in six domains of disability (household, cognitive, mobility, self-care, social and society). Univariate analysis, correlation and comparison tests as well as hierarchical multiple linear regression were performed. Results The median WHODAS score in the accessible and stable (AS), remote and stable (RS), intermediate (I) and unstable (U) HZ was 6.3 (0–28.6); 25 (6.3–41.7); 22.9 (12.5–33.3) and 39.6 (22.9–54.2), respectively. Four of the six WHODAS domain scores (household, cognitive, mobility and society) were the most altered in the UHZs. The RSHZ and IHZ had statistically comparable global WHODAS scores. The stable HZs (accessible and remote) had statistically lower scores than the UHZ on all items. In regression analysis, the factors significantly associated with an overall poor health status (or higher WHODAS score) were advanced age, being woman, being membership of an association; being divorced, separated or widower and living in an unstable HZ. Conclusions Armed conflicts have a significantly negative impact on people’s perceived health, particularly in crisis health zones. In this area, we must accentuate actions aiming to strengthen people’s psychosocial well-being.

The effect of mentorship as a means of strengthening leadership in the health system at the operational level: a case study of the Walungu rural health zone in the eastern Democratic Republic of Congo

“…However, in 2018, the trend curves indicated a significant disruption in progress due to events such as the loss of skilled human resources and an epidemic emergency, as reported by our respondents. Similar constraints have been noted in other low-income contexts, where the success of interventions like RIPSEC not only relies on initial outcomes but also on the health system's resilience to acute emergencies and the sustainability of funding and managerial practices (4,22,49,50). These findings suggest that while programs like RIPSEC can positively impact health outcomes, they are insufficient on their own to overcome all challenges.…”

“…Scores were adjusted based on expected results and predefined standards, allowing for comparative analysis. Walungu's performance in the 13 selected indicators was benchmarked comparatively to standards used by the DRC's health system to assess HZs achievements (4,31,33). Results were illustrated through curves showing changes from 2014 to 2019.…”

“…(3). This reality is starkly evident in the east of the Democratic Republic of Congo (DRC), where decades of armed conflict have fostered a persistent crisis (4). The ongoing conflict has gradually eroded infrastructure and led to an inadequate distribution of healthcare resources (1), while the state struggles to finance quality, accessible health services for all.…”

“…The results of the correlation test process with MRL can be seen in Table 2. Table . 2 shows that the results of the R. Square test produced have a significant level of relationship all predictor variables (X) and the output (Y) [44]. Based on the output obtained, the value of the R. Square test results obtained is 90.7%.…”

Etiologies and factors associated with mortality in patients with non-traumatic coma in a tertiary hospital in Bukavu, eastern Democratic Republic of the Congo

“…Bukavu, the capital city of the province of South-Kivu in eastern DRC, has a population of approximately one million (density: 16,600 inhabitants/km 2 ) [ 14 ]). This war-torn province has experienced socioeconomic and political instability since the late 1990s, impacting the well-being of its population [ [15] , [16] , [17] ].…”
