Prevalence of Cardiovascular Disease Risk Factors in the Gambia: A Systematic Review

Cardiovascular risk factors in Moroccan women: systematic review and meta-analysis

BACKGROUND

Cardiovascular diseases (CVD) are the major cause of disability and premature death. This is due to the ascending trend of consuming an unhealthy diet and obesity which increases the risk of hypertension and type 2 diabetes mellitus. The main aim of this review was to fill the knowledge gap by providing an up-to-date overview of the prevalence of CVD risk factors among women and to estimate the pooled prevalence among adolescent and pregnant women in Morocco.

METHODS

The review included original cross-sectional studies reporting the prevalence of CVD risk factors in Moroccan women aged ≥ 15 years, published between January 2008 and December 2022. The databases searched included MEDLINE, Scopus, Web of Science, Google Scholar and national government publications (PROSPERO ID: CRD42023426809).

RESULTS

Initially, 1471 articles were identified, and 76 studies were included. The most commonly reported CVD risk factor was obesity (reported in 56 studies), the prevalence of obesity varies according to the age groups of women with the rate being particularly high in urban women aged ≥ 35 years (ranging of 14-44.9%). Followed by diabetes (ranging from 7.2 to 12.6%) with a high rate in menopausal women. Hypertension prevalence ranged from 29.8 to 39.29%. Among adolescents, the overall prevalence of obesity was 3.15% (95% CI: 2.6%, 3.7%) and the prevalence of physical inactivity was 56.5% (95% CI: 36.9 - 76%). Among pregnant women, the overall prevalence of obesity was 26.8% (95% CI: 15.5 - 38.2%). Gestational diabetes and hypertension were 15.2% (95% CI: 6.3 - 24.1%) and 7.07% (95% CI: 2.5 - 11.6%), respectively.

CONCLUSION

This review highlights the significant burden of CVD risk factors among Moroccan women, with a high prevalences of diabetes, obesity, hypertension. The prevalences of these risk factors varies with age, being notably higher in older age groups. These findings underscore the need for targeted public health interventions to address these risk factors. Future research should focus on longitudinal studies and standardized assessment tools to enhance the robustness of prevalence estimates and inform effective prevention strategies.

Managing hypertension in rural Gambia and Kenya: Protocol for a qualitative study exploring the experiences of patients, health care workers, and decision-makers

Background

Hypertension is the single leading risk factor for premature death in Sub-Saharan Africa (SSA). Prevalence is high, but awareness, treatment, and control are low. Community-centred interventions show promise for effective hypertension management, but embedding such interventions sustainably requires a good understanding of the wider context within which they are being introduced. This study aims to conduct a systematic health system assessment exploring the micro (patients/carers), meso (health care workers and facilities), and macro (broader system) contexts in rural Gambia and Kenya.

Methods

This study will utilise various qualitative approaches. We will conduct (i) focus group discussions with people living with hypertensive to map a 'typical' patient journey through health systems, and (ii) in-depth interviews with patients and family carers, health care workers, decision-makers, and NCD partners to explore their experiences of managing hypertension and assess the capacity and readiness of the health systems to strengthen hypertension management. We will also review national guidelines and policy documents to map the organisation of services and guidance on hypertension management. We will use thematic analysis to analyse data, guided by the cumulative complexity model, and theories of organisational readiness and dissemination of innovations.

Expected findings

This study will describe the current context for the management of hypertension from the perspective of those involved in seeking (patients), delivering (health care workers) and overseeing (decision-makers) health services in rural Gambia and Kenya. It will juxtapose what should be happening according to health system guidance and what is happening in practice, drawing on the experiences of study participants. It will outline the various barriers to and facilitators of hypertension management, as perceived by patients, providers, and decision-makers, and the conditions that would need to be in place for effective and sustainable implementation of a community-centred intervention to improve the management of hypertension in rural settings.

Social determinants of health and hypertension screening among women in The Gambia: an evaluation of 2019-2020 demographic and health survey data

Hypertension is a leading modifiable risk factor for morbidity and mortality among women in Sub-Saharan Africa. Social determinants of health (SDH) are associated with sex-based differences in access to preventative screenings globally. Little research has assessed the influence of SDH on screening for hypertension among women in The Gambia. The aim of this study was to identify SDH associated with the utilization of hypertension screening among women in The Gambia. Data was examined from the 2019-2020 Gambia Demographic and Health Survey. Weighted multivariate logistic was used to identify whether SDH were associated with hypertension screening. Among 4116 women, over one-fifth (21.1%) had not been screened for hypertension in their lifetime. In fully adjusted models, older age, rural residence, higher than secondary educational attainment, employment, identification with specific ethnic groups, richer wealth status, parity (1 or more), and antenatal care visits increased the likelihood of lifetime hypertension screening. Women who indicated that others made their healthcare decisions for them (partners or someone else) were significantly less likely to have been screened for hypertension in their lifetime than women who made their healthcare decisions alone (adjusted odds ratio = 0.552, 95% confidence interval = (0.384-0.794)). SDH influence access to screening for hypertension among women in The Gambia. Initiatives may need to address the role of SDH to improve access and uptake of hypertension screening.

Prevalence of hypertension, diabetes, obesity, multimorbidity, and related risk factors among adult Gambians: a cross-sectional nationwide study

BACKGROUND

As countries progress through economic and demographic transition, chronic non-communicable diseases (NCDs) overtake a previous burden of infectious diseases. We investigated the prevalence of hypertension, diabetes, obesity, and multimorbidity in older adults in The Gambia.

METHODS

We embedded a survey on NCDs into the nationally representative 2019 Gambia National Eye Health Survey of adults aged 35 years or older. We measured anthropometrics, capillary blood glucose, and blood pressure together with sociodemographic information, personal and family health history, and information on smoking and alcohol consumption. Hypertension was defined as systolic blood pressure of 140 mmHg or more, diastolic blood pressure of 90 mmHg or more, or receiving treatment for hypertension. Diabetes was defined as fasting capillary blood glucose of 7 mmol/L or more, random blood glucose of 11·1mmol/L or more, or previous diagnosis or treatment for diabetes. Overweight was defined as BMI of 25-29·9 kg/m2 and obesity as 30 kg/m2 or more. Multimorbidity was defined as the coexistence of two or more conditions. We calculated weighted crude and adjusted estimates for each outcome by sex, residence, and selected sociodemographic factors.

FINDINGS

We analysed data from 9188 participants (5039 [54·8%] from urban areas, 6478 [70·5%] women). The prevalence of hypertension was 47·0%; 2259 (49·3%) women, 2052 (44·7%) men. The prevalence increased with age, increasing from 30% in those aged 35-45 years to over 75% in those aged 75 years and older. Overweight and obesity increased the odds of hypertension, and underweight reduced the odds. The prevalence of diabetes was 6·3% (322 [7·0%] women, 255 [5·6%] men), increasing from 3·8% in those aged 35-44 years to 9·1% in those aged 65-75 years, and then declining. Diabetes was much more common among urban residents, especially in women (peaking at 13% by age 65 years). Diabetes was strongly associated with BMI and wealth index. The prevalence of obesity was 12·0% and was notably higher in women than men (880 [20·2%] vs 170 [3·9%]). Multimorbidity was present in 932 (10·7%), and was more common in women than men (694 [15·9] vs 238 [5·5]). The prevalence of smoking was 9·7%; 5 (0·1%) women, 889 (19·3%) men. Alcohol consumption in the past year was negligible.

INTERPRETATION

We have documented high levels of NCDs and associated risk factors in Gambian adults. This presents a major stress on the country's fragile health system that requires an urgent, concerted, and targeted mutisectoral strategy.

Lived experience of diet-related health education in type 2 diabetes and hypertension comorbidity in The Gambia

The incidence and prevalence of type 2 diabetes mellitus (T2DM) and hypertension (and their comorbidity) have been increasing in sub-Saharan Africa, including The Gambia. Diet is a critical driver of these public health problems, and diet-related health education is a major strategy employed for their prevention and management. The aim of this paper is to explore the lived experiences of diet-related health education among individuals with comorbid type 2 diabetes and hypertension in Serrekunda, The Gambia, a subject hitherto unexplored in the country. The study employed a qualitative (interpretivist) methodology. Thirty-two interviews were conducted with 18 participants, with most participating in two interviews at separate time-points between November 2018 and July 2019. In addition to participant validation, the two points in time interviews elicited more depth and provided rich data. The data were analysed using Braun and Clarke's six-phased approach to Thematic Analysis. Four main themes were generated in relation to the experiences: (i) one-off blanket dietary advice (ii) education in a vacuum (iii) diabetes-hypertension diet dichotomy and (iv) imbalanced power relationship. The study underscores the need for a reconfiguration of diet-related health education in The Gambia to include lived experiences as critical components of health promotion in tackling T2DM and hypertension. This requires an ecological approach, critical health education, regulations on unhealthy foods, and active participation of individuals as equal partners in health education.

Determinants of Dyslipidemia in Africa: A Systematic Review and Meta-Analysis

Background

Dyslipidemia is a common public health problem in Africa. It has emerged as an important cardiovascular risk factor. It has been steadily increasing due to economic growth, urbanization, and unhealthy dietary pattern. Therefore, it is essential to identify determinants of dyslipidemia to prevent the condition and reduce its long-term sequel.

Methods

Combinations of search terms with Boolean operators were used to retrieve studies from PubMed, EMBASE, Cochrane Database, Cinahl, Scopus, Mednar, and Google Scholar. The methodological quality of each article was evaluated based on the 2017 Joanna Briggs Institute (JBI) Critical Appraisal checklist for prevalence studies. After evaluation of each study against these criteria, studies with a minimum score of 7 or above out of 9 JBI checklists were included. We included articles presented in the English language. The Cochrane Q test was used to assess the heterogeneity across studies. The visual assessment of publication bias was done by creating a funnel plot. The possible causes of heterogeneity were explored by subgroup analyses. Egger's weighted regression test was used to assess the presence of publication bias. Statistical analyses were done by using the STATA software version 14.

Result

A total of 24 articles involving 37,902 participants from 10 African countries were included. The overall pooled prevalence of dyslipidemia was 52.8 (95% CI 40.8–64.9). Individuals with a body mass index (BMI) >25.0 kg/m² and waist circumference (WC) >94 cm were, respectively, 2.36 (95% CI (1.33–4.18), p < 0.001) and 2.33 (95% CI (0.75–0.29) p < 0.001) times more likely to develop dyslipidemia than those with lower values. Furthermore, patients with diabetes mellitus (DM) and hypertension (HTN) were 2.32 (95% CI (0.89–6.05) p < 0.001) and 2.05 (95% CI (1.31–3.21), p < 0.001) times more likely to present with dyslipidemia than non-diabetic patients and those without HTN.

Conclusion

This study revealed that the prevalence of dyslipidemia is relatively high among study participants in African countries and the independent predictors of dyslipidemia were BMI >25.0 kg/m², WC > 94 cm, raised blood glucose level, and raised blood pressure. Therefore, there should be a pressing public health measure to prevent, identify, and treat dyslipidemia with the special emphasis on obese, diabetic, and hypertensive patients.

Increased serum levels of cadmium are associated with an elevated risk of cardiovascular disease in adults

Previous studies have determined the effects of exposure to certain heavy metals on cardiovascular disease (CVD); however, the association between cadmium exposure and CVD in adults remains unclear. The relationship between serum levels of cadmium and the risk of CVD was studied by analyzing available data from 38,223 different participants of the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2016. After adjusting for all covariates, we found that higher serum cadmium concentrations were positively related to both the overall risk of CVD (odds ratio (OR): 1.45; 95% confidence interval (CI): 1.22, 1.72; p for trend <0.001) and the risks of its subtypes, including congestive heart failure, coronary heart disease, heart attack, and stroke. Elevated cadmium levels were associated with increased levels of lipids and inflammatory factors, including blood triglycerides, total cholesterol, white blood cells (WBCs), and C-reactive protein (CRP). Our study provided epidemiological evidence that cadmium may increase the risk of CVD by elevating blood lipids and inflammation.

Chia seeds oil enriched with phytosterols and mucilage as a cardioprotective dietary supplement towards inflammation, oxidative stress, and dyslipidemia

Introduction: Non-communicable diseases are a cluster of metabolic diseases, which include type-2 diabetes, cancer, and cardiovascular diseases (CVDs). The aim of the current research was to incorporate dietary fibers (mucilage) and phytosterol for enriching chia seeds oil for producing new dietary supplements for cardio-protection from oxidative stress, inflammation, and dyslipidemia. Methods: Fatty acids profile, phytosterols, and phenolic compounds content of the prepared dietary supplement were assessed. The cardioprotective potency of the dietary supplement was evaluated in rats fed on a high-fat diet for a month. Biochemical parameters related to inflammation, oxidative stress, lipid profile, cardiac enzymes, and kidney function were determined in all rats. Results: The results revealed that dietary supplement was rich in omega-3 fatty acids. Beta-sitosterol and campesterol were the major phytosterols in chia seeds oil dietary supplement. Phenolic compounds were present by 25.9 ± 1.202 mg gallic acid equivalent (GAE)/g dietary supplements. Rats fed on the high-fat diet showed significant elevation (P < 0.05) in inflammatory markers, oxidative stress, dyslipidemia, and cardiac enzymes in association with the elevation of kidney function compared with normal rats. Administration of both doses of dietary supplement significantly (P < 0.05) improved all the studied biochemical parameters. The high dose of the dietary supplement was promising in the reduction of inflammatory markers, oxidative stress, and improved dyslipidemia in accordance with the reduction of all cardiac enzymes and kidney function. Conclusion: Dietary supplements investigated in the current research showed cardioprotective potency through its anti-inflammatory and dyslipidemic activities, which may be attributed to the presence of phenolic compounds, omega-3 fatty acids, phytosterols, and soluble dietary fibers.
