Adaptation and validation of the All Aspects of Health Literacy Scale (AAHLS) in healthcare settings of Addis Ababa, Ethiopia.

BACKGROUND: Since health literacy is known to be related to health outcomes, it should be measured to explain how it is associated with the health status of the population. Health literacy tools are designed to measure different dimensions of health literacy of individuals based on their objective. The AAHLS tool is comprehensive and can cover all aspects of health literacy. Overall in Ethiopia, there is no standard health literacy tool that has been developed or/and validated. Therefore, the aim of this study was to adapt and validate the All Aspects of Health Literacy Scale (AAHLS) in healthcare facilities in Addis Ababa city, Ethiopia. METHODS: A mixed-method, facility-based, cross-sectional study was conducted in Addis Ababa city from February 1, 2022, to May 30, 2022. The study was conducted in three phases: forward and backward translation and expert review, cognitive interviews and survey administration. For the cognitive interviews, a total of 16 participants and for the survey administration, 199 participants were involved. Coding and analysis of the qualitative data were performed using OpenCode 4.03 computer software. Then, pretesting (survey administration) was conducted to check the validity and reliability of the tool. CFA was conducted using SPSS version 26 and Stata version 14. RESULTS AND DISCUSSION: The original three response categories were revised to five response categories based on the cognitive interview findings and expert reviews. The survey was administered to 199 participants, 55.8% of whom were males. The Kaiser‒Meyer‒Olkin measure of sampling adequacy was 0.685, with a significant difference according to Bartlett's test of sphericity (p < 0.001). After removing the empowerment factor model fit indices, the internal reliability and convergent and divergent validities improved. Confirmatory factor analysis showed that the model fit indices of the tool were satisfactory. The overall internal consistency, Cronbach's alpha, was 0.71. CONCLUSION: The three response categories of the tool were revised to five response categories. The AAHLS tool was revised to include 10 items. The tool has exhibited adequate model fitness. The validated tool can be used for future health literacy assessments and interventions.

Effectiveness of community-based interventions for prevention and control of hypertension in sub-Saharan Africa: A systematic review.

Hypertension poses a significant public health challenge in sub-Saharan Africa due to various risk factors. Community-based intervention for prevention and control of hypertension is an effective strategy to minimize the negative health outcomes. However, comprehensive systematic review evidence to inform effective community-based interventions for prevention and control of hypertension in low resource settings is lacking. This study aimed to synthesize the effectiveness of community-based interventions on prevention and control of hypertension in sub-Saharan Africa. A comprehensive search for studies was carried out on PubMed, CINAHL, Web of Science Core Collection, Embase, Scopus, and Google scholar databases. The result of the review was reported according to PRISMA guidelines. Studies published in English language were included. Two independent reviewers conducted critical appraisal of included studies and extracted the data using predefined excel sheet. Experimental, quasi experimental, cohort and analytical cross-sectional studies conducted on adults who have received community-based interventions for prevention and controls of hypertension in sub-Saharan Africa were included. In this systematic review, a total of eight studies were included, comprising of two interventional studies, two quasi-experimental studies, three cohort studies, and one comparative cross-sectional study. The interventions included health education, health promotion, home-based screening and diagnosis, as well as referral and treatment of hypertensive patients. The sample sizes ranged from 236 to 13,412 in the intervention group and 346 to 6,398 in the control group. This systematic review shows the effect of community-based interventions on reduction of systolic and diastolic blood pressure. However, the existing evidence is inconsistence and not strong enough to synthesize the effect of community-based interventions for the prevention and control of hypertension in sub-Saharan Africa. Hence, further primary studies need on the effect of community-based interventions for the prevention and control of hypertension in sub-Saharan Africa.

Pregnant Women's Intentions to Deliver at a Health Facility in the Pastoralist Communities of Afar, Ethiopia: An Application of the Health Belief Model.

Despite the significant benefits of giving birth at a health facility to improve maternal and child health, the practice remains lower than expected in pastoralist communities of Ethiopia. Understanding the intentions of pregnant women to use health facilities for delivery predicts the adoption of the behavior, yet documented evidence of intention in the context of pastoralist populations remains scarce. The current study aimed to assess pregnant women's intentions to use a health facility for delivery in the Afar region of Ethiopia using the framework of the health belief model (HBM). A community-based, cross sectional survey was conducted from April 1 to April 30 2016 among 357 randomly sampled pregnant women using an interviewer-administered, semi-structured questionnaire. Data were entered into EpiData and exported to SPSS version 20.0 for analysis. Principal component factor analysis was done to extract relevant constructs of the model, and the reliability of items in each construct was assessed for acceptability. Multivariate logistic regressions were applied to identify predictors of pregnant women's intentions to give birth at a health facility. The odds ratio was reported, and statistical significance was declared at 95% CI and 0.05 p value. Three hundred fifty seven pregnant women participated in the study (104.6% response rate indicating above the minimum sample size required). Among the respondents, only 108 (30.3%) participants intended to use a health facility for the delivery for their current pregnancy. Higher household average monthly income [AOR = 1.23, 95% CI = (1.10 - 2.90), antenatal clinic (ANC) attendance for their current pregnancy [AOR = 1.41, 95% CI = (1.31 - 2.10), perceived susceptibility to delivery-related complications [AOR = 1.52, 95% CI = (1.30 - 2.70), and perceived severity of the delivery complications [AOR = 1.66, 95% CI = (1.12 - 2.31) were positively associated with pregnant women's intentions to deliver at a health facility. Intention was negatively associated with participants' perceived barriers to accessing a health facility [AOR = 0.62, 95% CI = (0.36 - 0.85). Conclusions: A low proportion of pregnant women in the sampled community intended to deliver at a health facility. Pastoralist communities may have special needs in this regard, with household income, antenatal care attendance, perceived risk of complications, and perceived barriers to accessing a health facility largely explaining the variance in intention. Community-based interventions providing counseling and messaging on danger signs in the perinatal period and emphasizing benefits of delivering at a facility are recommended, alongside improving access.
