Cardiovascular disease risk prediction in sub-Saharan African populations — Comparative analysis of risk algorithms in the RODAM study
(International Journal of Cardiology, 2018-03) Boateng, D.; Agyemang, C.; Beune, E.; Meeks, K.; Smeeth, L.; Schulze, M.B.; Addo, J.; de-Graft Aikins, A.; Galbete, C.; Bahendeka, S.; Danquah, I.; Agyei-Baffour, P.; Owusu-Dabo, E.; Mockenhaupt, F.P.; Spranger, J.; Kengne, A.P.; Grobbee, D.E.; Klipstein-Grobusch, K.
Background: Validated absolute risk equations are currently recommended as the basis of cardiovascular disease (CVD) risk stratification in prevention and control strategies. However, there is no consensus on appropriate equations for sub-Saharan African populations. We assessed agreement between different cardiovascular risk equations among Ghanaian migrant and home populations with no overt CVD. Methods: The 10-year CVD risks were calculated for 3586 participants aged 40–70 years in the multi-centre RODAM study among Ghanaians residing in Ghana and Europe using the Framingham laboratory and non-laboratory and Pooled Cohort Equations (PCE) algorithms. Participants were classified as low, moderate or high risk, corresponding to < 10%, 10–20% and > 20% respectively. Agreement between the risk algorithms was assessed using kappa and correlation coefficients. Results: 19.4%, 12.3% and 5.8% were ranked as high 10-year CVD risk by Framingham non-laboratory, Framingham laboratory and PCE, respectively. The median (25th–75th percentiles) estimated 10-year CVD risk was 9.5% (5.4–15.7), 7.3% (3.9–13.2) and 5.0% (2.3–9.7) for Framingham non-laboratory, Framingham laboratory and PCE, respectively. The concordance between PCE and Framingham non-laboratory was better in the home Ghanaian population (kappa = 0.42, r = 0.738) than the migrant population (kappa = 0.24, r = 0.732) whereas concordance between PCE and Framingham laboratory was better in migrant Ghanaians (kappa = 0.54, r = 0.769) than the home population (kappa = 0.51, r = 0.758). Conclusion: CVD prediction with the same algorithm differs for the migrant and home populations and the interchangeability of Framingham laboratory and non-laboratory algorithms is limited. Validation against CVD outcomes is needed to inform appropriate selection of risk algorithms for use in African ancestry populations. © 2017 The Authors
Effect of socio-economic factors in utilization of different healthcare services among older adult men and women in Ghana
(BioMed Central Ltd., 2016) Saeed, B.I.I.; Yawson, A.E.; Nguah, S.; Agyei-Baffour, P.; Emmanuel, N.; Ayesu, E.
Background: The older adult population is increasing all over the world. In sub-Saharan Africa, due to poverty and low policy coverage, older adults are not well catered for. The effect of socio-economic inequality in the use of healthcare services among older adult men and women in Ghana was investigated in this paper. Methods: The data employed in the study were drawn from Global Ageing and Adult Health survey SAGE Wave 1 Ghana and was based on the design for the World Health Survey 2003, SAGE Wave 0, Ghana. The survey was conducted in 2007-2008 and collected data on socio-economic characteristics and other variables of the 5573 individuals interviewed. Results: Using generalized logit model, the study found that health status is a very strong determinant of the type of healthcare services preferred by older adults Ghanaians. Men with higher income preferred the private health facilities, while those who completed tertiary education, those with health insurance and those who self-rated their health as very bad, bad or moderate preferred public facility. Self-employed men and those in informal employment, preferred other health facilities outside the formal public health service. Women with primary and secondary education, preferred the private health facilities. Women with health insurance, those in middle and upper class income quintiles or those with self-rated bad and moderate health status or being relatively younger preferred the public facility to other health services. Self-employed women and those in informal employment preferred traditional treatment. In Ghana, there are important socio-economic gradients in the use of some healthcare services. In both sexes, those without insurance and rural residents preferred the pharmacy and traditional treatment. Conclusion: These differences may be due to socio-economic inequities but could also indicate that the existing health facilities are not always used in an optimal way. Patient factors may be equally important as supply factors in explaining the differential use of health services. The public health systems in Ghana still have a major role in improving the health of older adults. National commitments in providing basic essential infrastructure and personnel to health centres for the citizenry is imperative. Policy readjustment of the national health insurance scheme to make it truly accessible to the aged is essential.
Feasibility and acceptability of ACT for the community case management of malaria in urban settings in five African sites
(2011-08-16) Akweongo, P.; Agyei-Baffour, P.; Sudhakar, M.; Simwaka, B.N.; Konaté, A.T.; Adongo, P.B.; Browne, E.N,; Tegegn, A.; Ali, D.; Amunyunzu-Nyamongo, M.; Pagnoni, F.; Barnish, G.
The community case management of malaria (CCMm) is now an established route for distribution of artemisinin-based combination therapy (ACT) in rural areas, but the feasibility and acceptability of the approach through community medicine distributors (CMD) in urban areas has not been explored. It is estimated that in 15 years time 50% of the African population will live in urban areas and transmission of the malaria parasite occurs in these densely populated areas. METHODS: Pre- and post-implementation studies were conducted in five African cities: Ghana, Burkina Faso, Ethiopia and Malawi. CMDs were trained to educate caregivers, diagnose and treat malaria cases in < 5-year olds with ACT. Household surveys, focus group discussions and in-depth interviews were used to evaluate impact. RESULTS: Qualitative findings: In all sites, interviews revealed that caregivers' knowledge of malaria signs and symptoms improved after the intervention. Preference for CMDs as preferred providers for malaria increased in all sites.Quantitative findings: 9001 children with an episode of fever were treated by 199 CMDs in the five study sites. Results from the CHWs registers show that of these, 6974 were treated with an ACT and 6933 (99%) were prescribed the correct dose for their age. Fifty-four percent of the 3,025 children for which information about the promptness of treatment was available were treated within 24 hours from the onset of symptoms.From the household survey 3700 children were identified who had an episode of fever during the preceding two weeks. 1480 (40%) of them sought treatment from a CMD and 1213 of them (82%) had received an ACT. Of these, 1123 (92.6%) were administered the ACT for the correct number of doses and days; 773 of the 1118 (69.1%) children for which information about the promptness of treatment was available were treated within 24 hours from onset of symptoms, and 768 (68.7%) were treated promptly and correctly. CONCLUSIONS: The concept of CCMm in an urban environment was positive, and caregivers were generally satisfied with the services. Quality of services delivered by CMDs and adherence by caregivers are similar to those seen in rural CCMm settings. The proportion of cases seen by CMDs, however, tended to be lower than was generally seen in rural CCMm. Urban CCMm is feasible, but it struggles against other sources of established healthcare providers. Innovation is required by everyone to make it viable.

Food variety, dietary diversity, and type 2 diabetes in a multi-center cross-sectional study among Ghanaian migrants in Europe and their compatriots in Ghana: the RODAM study
(European Journal of Nutrition, 2017-09) Danquah, I.; Galbete, C.; Meeks, K.; Nicolaou, M.; Klipstein-Grobusch, K.; Addo, J.; Aikins, A.D.-G.; Amoah, S.K.; Agyei-Baffour, P.; Boateng, D.; Bedu-Addo, G.; Spranger, J.; Smeeth, L.; Owusu-Dabo, E.; Agyemang, C.; Mockenhaupt, F.P.; Beune, E.; Schulze, M.B.
Purpose: The importance of dietary diversification for type 2 diabetes (T2D) risk remains controversial. We investigated associations of between- and within-food group variety with T2D, and the role of dietary diversification for the relationships between previously identified dietary patterns (DPs) and T2D among Ghanaian adults. Methods: In the multi-center cross-sectional Research on Obesity and Diabetes among African Migrants (RODAM) Study (n = 3810; Ghanaian residence, 56%; mean age, 46.2 years; women, 63%), we constructed the Food Variety Score (FVS; 0–20 points), the Dietary Diversity Score (DDS; 0–7 points), and the Diet Quality Index-International (DQI-I) variety component (0–20 points). The associations of these scores, of a “rice, pasta, meat and fish” DP, of a “mixed” DP, and of a “roots, tubers and plantain” DP with T2D were calculated by logistic regression. Results: The FVS was inversely associated with T2D, adjusted for socio-demographic, lifestyle, and anthropometric factors [odds ratio (OR) for T2D per 1 standard deviation (SD) increase: 0.81; 95% confidence interval (CI) 0.71–0.93]. The DDS and the DQI-I variety component were not associated with T2D. There was no association of the “mixed” DP and the “roots, tubers and plantain” DP with T2D. Yet, the “rice, pasta, meat and fish” DP is inversely associated with T2D (OR for T2D per 1 SD increase: 0.82; 95% CI 0.71–0.95); this effect was slightly attenuated by the FVS. Conclusions: In this Ghanaian population, between-food group variety may exert beneficial effects on glucose metabolism and partially explains the inverse association of the “rice, pasta, meat and fish” DP with T2D. © 2017 The Author(s)
For money or service? A cross-sectional survey of preference for financial versus non-financial rural practice characteristics among Ghanaian medical students.
(2011-11-03) Johnson, J.C.; Nakua, E.; Dzodzomenyo, M.; Agyei-Baffour, P.; Gyakobo, M.; Asabir, K.; Kwansah, J.; Kotha, S.R.; Snow, R.C.; Kruk, M.E.
Abstract Background Health worker shortage and maldistribution are among the biggest threats to health systems in Africa. New medical graduates are prime targets for recruitment to deprived rural areas. However, little research has been done to determine the influence of workers' background and future plans on their preference for rural practice incentives and characteristics. The purpose of this study was to identify determinants of preference for rural job characteristics among fourth year medical students in Ghana. Methods We asked fourth-year Ghanaian medical students to rank the importance of rural practice attributes including salary, infrastructure, management style, and contract length in considering future jobs. We used bivariate and multivariate ordinal logistic regression to estimate the association between attribute valuation and students' socio-demographic background, educational experience, and future career plans. Results Of 310 eligible fourth year medical students, complete data was available for 302 students (97%). Students considering emigration ranked salary as more important than students not considering emigration, while students with rural living experience ranked salary as less important than those with no rural experience. Students willing to work in a rural area ranked infrastructure as more important than students who were unwilling, while female students ranked infrastructure as less important than male students. Students who were willing to work in a rural area ranked management style as a more important rural practice attribute than those who were unwilling to work in a rural area. Students studying in Kumasi ranked contract length as more important than those in Accra, while international students ranked contract length as less important than Ghanaian students. Conclusions Interventions to improve rural practice conditions are likely to be more persuasive than salary incentives to Ghanaian medical students who are willing to work in rural environments a priori. Policy experiments should test the impact of these interventions on actual uptake by students upon graduation.

Gender disparities of chronic musculoskeletal disorder burden in the elderly Ghanaian population: study on global ageing and adult health (SAGE WAVE 1)
(BMC Musculoskeletal Disorders, 2015-08) Nakua, E.K.; Otupiri, E.; Dzomeku, V.M.; Owusu-Dabo, E.; Agyei-Baffour, P.; Yawson, A.E.; Folson, G.; Hewlett, S.
BACKGROUND: Traditionally, non-communicable diseases including musculoskeletal disorders have not been a priority in low-and-middle income countries. The main aim of this paper is to assess age and gender specific burden by estimating the current prevalence of musculoskeletal disorders and associated risk factors in the elderly Ghanaian population. METHODS: Between May 2007 and June 2008, the World Health Organization conducted a nationwide study on AGEing (SAGE) and Adult Health in Ghana. The study employed a multistage cluster sampling strategy to identify participants by stratifying the population by age and setting. A structured questionnaire was used for data collection. A Poisson regression model was fitted with robust error variance. Prevalence estimates took into account the complex survey design and sampling weights. Statistical significance was considered at p ≤ 0.05 significance level. Statistical analysis was performed with STATA version 11.2. RESULTS: The prevalence rates of chronic back pain and chronic arthritis/joints pain were higher in women than men. The overall crude prevalence's rates were 28.2 and 10.7% for chronic back pain and chronic arthritis/joints pain respectively. Substantial differences existed between men and women in terms of socio-economic status, education level and occupational status. Women with primary education had a chronic back pain prevalence of 36.2% (95% CI; 29.2, 43.3) and chronic arthritis/joints pain prevalence of 15.8% (95% CI; 11.1, 20.6) while their male counterparts had prevalence rates of 29.0% (95% CI; 23.4, 34.5) and 9.8% (95% CI; 6.4, 13.2) respectively. Residence (rural and urban) did not appear to influence the prevalence of chronic back pain and arthritis/joints pain. CONCLUSION: Our findings suggest the existence of sex differences in chronic back pain and chronic arthritis/joint pain in the elderly population in Ghana after adjustment for demographic and socio-economic factors. It indicates the existence of inequalities in health between elderly men and women with women suffering more from chronic back pain and chronic arthritis/joints pain.
Knowledge and awareness of and perception towards cardiovascular disease risk in sub-Saharan Africa: A systematic review
(PLoS ONE, 2017-12) Boateng, D.; Wekesah, F.; Browne, J.L.; Agyemang, C.; Agyei-Baffour, P.; De-Graft Aikins, A.; Smit, H.A.; Grobbee, D.E.; Klipstein-Grobusch, K.
Introduction Cardiovascular diseases (CVDs) are the most common cause of non-communicable disease mortality in sub-Saharan African (SSA) countries. Gaps in knowledge of CVD conditions and their risk factors are important barriers in effective prevention and treatment. Yet, evidence on the awareness and knowledge level of CVD and associated risk factors among populations of SSA is scarce. This review aimed to synthesize available evidence of the level of knowledge of and perceptions towards CVDs and risk factors in the SSA region. Methods Five databases were searched for publications up to December 2016. Narrative synthesis was conducted for knowledge level of CVDs, knowledge of risk factors and clinical signs, factors influencing knowledge of CVDs and source of health information on CVDs. The review was registered with Prospero (CRD42016049165). Results Of 2212 titles and abstracts screened, 45 full-text papers were retrieved and reviewed and 20 were included: eighteen quantitative and two qualitative studies. Levels of knowledge and awareness for CVD and risk factors were generally low, coupled with poor perception. Most studies reported less than half of their study participants having good knowledge of CVDs and/or risk factors. Proportion of participants who were unable to identify a single risk factor and clinical symptom for CVDs ranged from 1.8% in a study among hospital staff in Nigeria to a high of 73% in a population-based survey in Uganda and 7% among University staff in Nigeria to 75.1% in a general population in Uganda respectively. High educational attainment and place of residence had a significant influence on the levels of knowledge for CVDs among SSA populations. Conclusion Low knowledge of CVDs, risk factors and clinical symptoms is strongly associated with the low levels of educational attainment and rural residency in the region. These findings provide useful information for implementers of interventions targeted at the prevention and control of CVDs, and encourages them to incorporate health promotion and awareness campaigns in order to enhance knowledge and awareness of CVDs in the region. © 2017 Boateng et al.

Lifecourse factors and likelihood of rural practice and emigration: A survey of Ghanaian medical students.
(2012-09-06) Kotha, S.R.; Johnson, J.C.; Galea, S.; Agyei-Baffour, P.; Nakua, E.; Asabir, K.; Kwansah, J.; Gyakobo, M.; Dzodzomenyo, M.; Kruk, M.E.
Introduction: Health worker shortages and maldistribution have important implications for the capacity of health systems. Ghana has one of the highest physician emigration rates in the world, and over 75% of those who remain work in Ghana's two largest cities. The aim of this study was to investigate the contribution of experiential factors across Ghanaian medical students' lifespans on intent to practice in a rural area and intent to emigrate. Methods: All fourth year medical students in Ghana were surveyed on demographics, rural and international experience, and future career plans. Key outcomes of interest were students' stated likelihood of practicing in a deprived rural area or emigrating after graduation. Lifecourse predictors of interest were parental socioeconomic status, gender, relationship status, rural and international living experience, and school of study. Bivariate and multivariate logistic regression were used to estimate associations between predictors and outcomes of interest. Results: Of 310 eligible students, 307 (99%) participated in the survey. Of these, 228 were Ghanaian and the focus of this analysis. It was found that 131 (57.5%) were willing to work in a deprived area in Ghana and 148 (64.9%) had considered emigrating after graduation. In the multivariate regression models, willingness to work in a deprived area was predicted by male gender (OR: 2.31, 95%CI: 1.23-4.35), having lived in a rural area but never lived abroad (OR: 2.77, 95%CI: 1.08-7.13), and low parental professional and educational status (OR: 2.33, 95%CI: 1.23-4.43). Consideration of emigration was predicted by having lived abroad but never in a rural area (OR: 3.39, 95%CI: 1.15-9.97). A sub-set of 80 individuals (35%) reported that they were willing to work in a deprived area in Ghana but also considering emigration. These subjects were more likely to be male. Conclusions: Students with parents of a lower socioeconomic class, those with rural experience, and those without international experience are more likely to stay in Ghana and are also more likely to work in a deprived area after graduation. Selective admissions policies based on lifecourse factors combined with exposure to rural practice in medical school may have a role in increasing the number of rural physicians. © SR Kotha, JC Johnson, S Galea, P Agyei-Baffour, E Nakua, K Asabir, J Kwansah, M Gyakobo, M Dzodzomenyo, ME Kruk, 2012.
Multi-TheoryModel and Predictors of Likelihood of Accepting the Series of HPV Vaccination: A Cross-Sectional Study among Ghanaian Adolescents
(International Journal of Environmental Research and Public Health, 2020-01-16) Owusu, A.B.; Asare, M.; Agyei-Baffour, P.; Lanning, B.A.; Commeh, M.E.; Boozer, K.; Koranteng, A.; Spies, L.A.; Montealegre, J.R.; Paskett, E.D.
HPV vaccines are e cacious in preventing HPV related cancers. However, the vaccination uptake in Ghana is very low. Studies that utilize theoretical frameworks to identify contributory factors to HPV vaccination uptake in Ghana are understudied. We used multi-theory model (MTM) constructs to predict initiation and completion of HPV vaccination series in Ghanaian adolescents. Adolescents (n = 285) between the ages of 12 and 17 years old were recruited from four selected schools in Ghana to participate in the cross-sectional study. Linear regressions were used to analyze the data. Most participants were female (91.2%) and senior high school students (60.0%). Many of the participants had neither heard about HPV (92.3%) nor HPV vaccinations (95.4%). Significant predictors of adolescents’ likelihood of getting the first dose of HPV vaccination were perceived beliefs and change in a physical environment (p < 0.001), with each variable accounting for 6.1%and 8.8% of the variance respectively. Significant predictors of adolescents’ likelihood of completing HPV vaccination recommended series were perceived beliefs, practice for change, and emotional transformation (p < 0.001), with each variable accounting for 7.8%, 8.1%, and 1.1% of the variance respectively. Findings underscore important opportunities for developing educational interventions for adolescents in Ghana to increase the HPV vaccination uptake.
Perceived barriers and motivating factors influencing student midwives’ acceptance of rural postings in Ghana
(2012-07-24) Lori, J.R.; Rominski, S.D.; Gyakobo, M.; Muriu, E.W; Kweku, N.E.; Agyei-Baffour, P.
Abstract Background Research on the mal-distribution of health care workers has focused mainly on physicians and nurses. To meet the Millennium Development Goal Five and the reproductive needs of all women, it is predicted that an additional 334,000 midwives are needed. Despite the on-going efforts to increase this cadre of health workers there are still glaring gaps and inequities in distribution. The objectives of this study are to determine the perceived barriers and motivators influencing final year midwifery students’ acceptance of rural postings in Ghana, West Africa. Methods An exploratory qualitative study using focus group interviews as the data collection strategy was conducted in two of the largest midwifery training schools in Ghana. All final year midwifery students from the two training schools were invited to participate in the focus groups. A purposive sample of 49 final year midwifery students participated in 6 focus groups. All students were women. Average age was 23.2 years. Glaser’s constant comparative method of analysis was used to identify patterns or themes from the data. Results Three themes were identified through a broad inductive process: 1) social amenities; 2) professional life; and 3) further education/career advancement. Together they create the overarching theme, quality of life, we use to describe the influences on midwifery students’ decision to accept a rural posting following graduation. Conclusions In countries where there are too few health workers, deployment of midwives to rural postings is a continuing challenge. Until more midwives are attracted to work in rural, remote areas health inequities will exist and the targeted reduction for maternal mortality will remain elusive.
Rationale and cross-sectional study design of the research on obesity and type 2 diabetes among African migrants: The RODAM study
(BMJ Open, 2014-03) Agyemang, C.; Beune, E.; Meeks, K.; Owusu-Dabo, E.; Agyei-Baffour, P.; De-Graft Aikins, A.; Dodoo, F.; Smeeth, L.; Addo, J.; Mockenhaupt, F.P.; Amoah, S.K.; Schulze, M.B.; Danquah, I.; Spranger, J.; Nicolaou, M.; Klipstein-Grobusch, K.; Burr, T.; Henneman, P.; Mannens, M.M.; Van Straalen, J.P.; Bahendeka, S.; Zwinderman, A.H.; Kunst, A.E.; Stronks, K.
Introduction: Obesity and type 2 diabetes (T2D) are highly prevalent among African migrants compared with European descent populations. The underlying reasons still remain a puzzle. Gene-environmental interaction is now seen as a potential plausible factor contributing to the high prevalence of obesity and T2D, but has not yet been investigated. The overall aim of the Research on Obesity and Diabetes among African Migrants (RODAM) project is to understand the reasons for the high prevalence of obesity and T2D among sub-Saharan Africans in diaspora by (1) studying the complex interplay between environment (eg, lifestyle), healthcare, biochemical and (epi)genetic factors, and their relative contributions to the high prevalence of obesity and T2D; (2) to identify specific risk factors within these broad categories to guide intervention programmes and (3) to provide a basic knowledge for improving diagnosis and treatment. Methods and analysis: RODAM is a multicentre cross-sectional study among homogenous sub-Saharan African participants (ie, Ghanaians) aged >25 years living in rural and urban Ghana, the Netherlands, Germany and the UK (http://rod-am.eu/). Standardised data on the main outcomes, genetic and non-genetic factors are collected in all locations. The aim is to recruit 6250 individuals comprising five subgroups of 1250 individuals from each site. In Ghana, Kumasi and Obuasi (urban stratum) and villages in the Ashanti region (rural stratum) are served as recruitment sites. In Europe, Ghanaian migrants are selected through the municipality or Ghanaian organisations registers. Ethics and dissemination: Ethical approval has been obtained in all sites. This paper gives an overview of the rationale, conceptual framework and methods of the study. The differences across locations will allow us to gain insight into genetic and non-genetic factors contributing to the occurrence of obesity and T2D and will inform targeted intervention and prevention programmes, and provide the basis for improving diagnosis and treatment in these populations and beyond.
Rural practice preferences among medical students in Ghana: A discrete choice experiment.
(2010) Kruk, M.E.; Johnson, J.C.; Gyakobo, M.; Agyei-Baffour, P.; Asabir, K.; Kotha, S.R.; Kwansah, J.; Nakua, E.; Snow, R.C.; Dzodzomenyo, M.
Objective To determine how specific job attributes influenced fourth year medical students' stated preference for hypothetical rural job postings in Ghana. Methods Based on discussions with medical student focus groups and physicians in practice and in the Ministry of Health, we created a discrete choice experiment (DCE) that assessed how students' stated preference for certain rural postings was influenced by various job attributes: a higher salary, free superior housing, an educational allowance for children, improved equipment, supportive management, shorter contracts before study leave and a car. We conducted the DCE among all fourth year medical students in Ghana using a brief structured questionnaire and used mixed logit models to estimate the utility of each job attribute. Findings Complete data for DCE analysis were available for 302 of 310 (97%) students. All attribute parameter estimates differed significantly from zero and had the expected signs. In the main effects mixed logit model, improved equipment and supportive management were most strongly associated with job preference (? = 1.42; 95% confidence interval, CI: 1.17 to 1.66, and ? = 1.17; 95% CI: 0.96 to 1.39, respectively), although shorter contracts and salary bonuses were also associated. Discontinuing the provision of basic housing had a large negative influence (? = -1.59; 95% CI: -1.88 to -1.31). In models including gender interaction terms, women's preferences were more influenced by supportive management and men's preferences by superior housing. Conclusion Better working conditions were strongly associated with the stated choice of hypothetical rural postings among fourth year Ghanaian medical students. Studies are needed to find out whether job attributes determine the actual uptake of rural jobs by graduating physicians.
Variations in hypertension awareness, treatment, and control among Ghanaian migrants living in Amsterdam, Berlin, London, and nonmigrant Ghanaians living in rural and urban Ghana-the RODAM study
(Journal of Hypertension, 2018-01) Agyemang, C.; Nyaaba, G.; Beune, E.; Meeks, K.; Owusu-Dabo, E.; Addo, J.; Aikins, A.D.-G.; Mockenhaupt, F.P.; Bahendeka, S.; Danquah, I.; Schulze, M.B.; Galbete, C.; Spranger, J.; Agyei-Baffour, P.; Henneman, P.; Klipstein-Grobusch, K.; Adeyemo, A. .; Van Straalen, J.; Commodore-Mensah, Y.; Appiah, L.T.; Smeeth, L.; Stronks, K.
Objectives: Hypertension is a major burden among African migrants, but the extent of the differences in prevalence, treatment, and control among similar African migrants and nonmigrants living in different contexts in high-income countries and rural and urban Africa has not yet been assessed. We assessed differences in hypertension prevalence and its management among relatively homogenous African migrants (Ghanaians) living in three European cities (Amsterdam, London, and Berlin) and nonmigrants living in rural and urban Ghana. Methods: A multicenter cross-sectional study was conducted among Ghanaian adults (n=5659) aged 25-70 years. Comparisons between sites were made using prevalence ratios with adjustment for age, education, and BMI. Results: The age-standardised prevalence of hypertension was 22 and 28% in rural Ghanaian men and women. The prevalence was higher in urban Ghana [men, 34%; adjusted prevalence ratio=1.37, 95% confidence interval (CI), 1.10-1.70]; and much higher in migrants in Europe, especially in Berlin (men, 57%; prevalence ratio=2.21, 1.78-2.73; women, 51%; prevalence ratio=1.74, 1.45-2.09) than in rural Ghana. Hypertension awareness and treatment levels were higher in Ghanaian migrants than in nonmigrant Ghanaians. However, adequate hypertension control was lower in Ghanaian migrant men in Berlin (20%; prevalence ratio=0.43 95%, 0.23-0.82), Amsterdam (29%; prevalence ratio=0.59, 0.35-0.99), and London (36%; prevalence ratio=0.86, 0.49-1.51) than rural Ghanaians (59%). Among women, no differences in hypertension control were observed. About 50% of migrants to 85% of rural Ghanaians with severe hypertension (Blood pressure>180/110) were untreated. Antihypertensive medication prescription patterns varied considerably by site. Conclusion: Hypertension prevalence, awareness, and treatment levels were generally higher in African migrants, but blood pressure control level was lower in Ghanaian migrant men compared with their nonmigrant peers. Further work is needed to identify key underlying factors to support prevention and management efforts.
Willingness to work in rural areas and the role of intrinsic versus extrinsic professional motivations - a survey of medical students in Ghana
(2011-08-09) Agyei-Baffour, P.; Kotha, S.R.; Johnson, J.C.; Gyakobo, M.; Asabir, K.; Kwansah, J.; Nakua, E.; Dzodzomenyo, M.; Snow, R.C.; Kruk, M.E
Abstract Background Retaining health workers in rural areas is challenging for a number of reasons, ranging from personal preferences to difficult work conditions and low remuneration. This paper assesses the influence of intrinsic and extrinsic motivation on willingness to accept postings to deprived areas among medical students in Ghana. Methods A computer-based survey involving 302 fourth year medical students was conducted from May-August 2009. Logistic regression was used to assess the association between students' willingness to accept rural postings and their professional motivations, rural exposure and family parental professional and educational status (PPES). Results Over 85% of students were born in urban areas and 57% came from affluent backgrounds. Nearly two-thirds of students reported strong intrinsic motivation to study medicine. After controlling for demographic characteristics and rural exposure, motivational factors did not influence willingness to practice in rural areas. High family PPES was consistently associated with lower willingness to work in rural areas. Conclusions Although most Ghanaian medical students are motivated to study medicine by the desire to help others, this does not translate into willingness to work in rural areas. Efforts should be made to build on intrinsic motivation during medical training and in designing rural postings, as well as favour lower PPES students for admission.
