(2017) Addo, J.; Agyemang, C.; de-Graft Aikins, A.; Beune, E.; Schulze, M.B.; Danquah, I.; Galbete, C.; Nicolaou, M.; Meeks, K.; Klipstein-Grobusch, K.; Bahendeka, S.; Mockenhaupt, F.P.; Owusu-Dabo, E.; Kunst, A.; Stronks, K.; Smeeth, L.
ACKGROUND: The prevalence of diabetes has been shown to be socially patterned but the direction of the association in low-income countries and among migrant populations in Europe has varied in the literature. This study examined the association between socioeconomic position (SEP) and diabetes in Ghanaians in Europe and in Ghana. METHODS: Data were derived from the multicentre Research on Obesity and Diabetes among African Migrants (RODAM) study of Ghanaian adults aged 25-70 years residing in Europe (Amsterdam, Berlin and London) and in urban and rural Ghana. Educational attainment (elementary, secondary or higher) and occupational class (low or high) were used as indicators of SEP. Age-standardised prevalence of diabetes and prevalence ratios were evaluated separately for men and women of different SEP in Ghana and Europe. RESULTS: A total of 5290 participants were included in the analyses. The prevalence of diabetes decreased with increasing level of education in Ghanaian men and women in Europe and in men in urban Ghana, whereas diabetes prevalence increased with increasing level of education in men and women in rural Ghana. The association between occupational class and the prevalence of diabetes followed a less consistent pattern in men and women in the different locations. CONCLUSIONS: The association of diabetes and SEP differed in rural Ghana compared with urban settings in Ghana and Europe and comparing men and women, highlighting the complex interaction of SEP and the development of diabetes. These findings have important implications for diabetes prevention strategies in Ghanaians in different locations.
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
Dietary patterns and type 2 diabetes among Ghanaian migrants in Europe and their compatriots in Ghana: The RODAM study
(Nature Publishing Group, 2018) Galbete, C.; Nicolaou, M.; Meeks, K.; Klipstein-Grobusch, K.; De-Graft Aikins, A.; Addo, J.; Amoah, S.K.; Smeeth, L.; Owusu-Dabo, E.; Spranger, J.; Agyemang, C.; Mockenhaupt, F.P.; Beune, E.; Stronks, K.; Schulze, M.B.; Danquah, I.
Background/objectives: We aimed to study the associations of dietary patterns (DPs) with type 2 diabetes (T2D) among Ghanaian adults. Subjects/methods: In the multi-centre, cross-sectional RODAM (Research on Obesity and Diabetes among African Migrants) study (n = 4543), three overall DPs ("mixed", "rice, pasta, meat and fish," and "roots, tubers and plantain") and two site-specific DPs per study site (rural Ghana, urban Ghana and Europe) were identified by principal component analysis. The DPs-T2D associations were calculated by logistic regression models. Results: Higher adherence to the "rice, pasta, meat and fish" DP (characterized by legumes, rice/pasta, meat, fish, cakes/sweets, condiments) was associated with decreased odds of T2D, adjusted for socio-demographic factors, total energy intake and adiposity measures (odds ratio (OR)per 1 SD = 0.80; 95% confidence interval (CI) = 0.70-0.92). Similar DPs and T2D associations were discernible in urban Ghana and Europe. In the total study population, neither the "mixed" DP (whole grain cereals, sweet spreads, dairy products, potatoes, vegetables, poultry, coffee/tea, sodas/juices, olive oil) nor the "roots, tubers and plantain" DP (refined cereals, fruits, nuts/seeds, roots/tubers/plantain, fermented maize products, legumes, palm oil, condiments) was associated with T2D. Yet, after the exclusion of individuals with self-reported T2D, the "roots, tubers and plantain" DP was inversely associated with T2D (ORper 1 SD = 0.88; 95% CI = 0.69-1.12). Conclusion: In this Ghanaian population, DPs characterized by the intake of legumes, fish, meat and confectionery were inversely associated with T2D. The effect of a traditional-oriented diet (typical staples, vegetables and legumes) remains unclear. © 2018 The Author(s).
Differences in Alcohol Consumption and Drinking Patterns in Ghanaians in Europe and Africa: The RODAM Study
(PloS one, 2018-11) Addo, J.; Cook, S.; Galbete, C.; Agyemang, C.; Klipstein-Grobusch, K.; Nicolaou, M.; Danquah, I.; Schulze, M.B.; Brathwaite, R.; Mockenhaupt, F.P.; Beune, E.; Meeks, K.; de-Graft Aikins, A.; Bahendaka, S.; Owusu-Dabo, E.; Smeeth, L.
BACKGROUND: Little is known about alcohol consumption among Africans living in rural and urban Africa compared to African migrants in Europe. We compared the patterns of alcohol consumption in a group of Ghanaians living in different locations in Ghana and in Europe and examined the factors associated with drinking alcohol. METHODS: Data were from a cross-sectional study (RODAM) of Ghanaians aged 25-70 years living in rural and urban Ghana and in Amsterdam, Berlin and London. Information on how often participants consumed at least one standard alcoholic drink in the preceding 12 months, the type of alcoholic beverage and the average serving size was obtained using a food propensity questionnaire. The associations between drinking alcohol and socio-demographic variables, and frequency of attending religious services were investigated using logistic regression models stratified by site and sex. For Ghanaians living in Europe, the number of years since migration and acculturation were also included in the model as covariates. RESULTS: 4280 participants (62.2% women) were included in the analyses. In both men and women, the prevalence of drinking and amount of alcohol consumed per day was highest in Berlin (prevalence of drinking 71.0% and 61.7%) and lowest in urban Ghana (41.4% and 26.8%). After adjustment for age and education in both men and women in Europe, those attending religious services less frequently reported higher levels of drinking alcohol than non-attendants (never attend/no religion compared to attending service at least once a week men OR 4.60 95% CI 2.85, 7.44; women OR 1.80 95% CI 1.12, 2.90) p-trend with frequency <0.001 in men; 0.002 in women); this association was seen also in men in rural Ghana (p-trend = 0.001) and women in urban Ghana (p-trend = 0.02). The prevalence of drinking was positively associated with years since migration in both men and women in Europe ((OR per years increase in time lived in Europe 1.25 (95% CI 1.02,1.53) test for trend p = 0.03 in women; OR 1.29 (95% CI 1.03, 1.62 p = 0.03 in men) but no association was found with self-reported measures of acculturation (ethnic identity, cultural orientation or social networks). CONCLUSION: There are marked differences in alcohol consumption between Ghanaians living in Europe and in Ghana suggesting migration has an important influence of drinking patterns and also suggesting the possibility of requiring different strategies in alcohol reduction campaigns among Ghanaians in different locations.
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)
Obesity and type 2 diabetes in sub-Saharan Africans - Is the burden in today's Africa similar to African migrants in Europe? The RODAM study.
(2016) Agyemang, C.; Meeks, K.; Beune, E.; Owusu-Dabo, E.; Mockenhaupt, F.P.; Addo, J.; de-Graft Aikins, A.; Bahendeka, S.; Danquah, I.; Schulze, M.B.; Spranger, J.; Burr, T.; Agyei-Baafour, P.; Amoah, S.K.; Galbete, C.; Henneman, P.; Klipstein-Grobusch, K.; Nicolaou, M.; Adeyemo, A.; van Straalen, J.; Smeeth, L.; Stronks, K.
BACKGROUND: Rising rates of obesity and type 2 diabetes (T2D) are impending major threats to the health of African populations, but the extent to which they differ between rural and urban settings in Africa and upon migration to Europe is unknown. We assessed the burden of obesity and T2D among Ghanaians living in rural and urban Ghana and Ghanaian migrants living in different European countries. METHODS: A multi-centre cross-sectional study was conducted among Ghanaian adults (n = 5659) aged 25-70 years residing in rural and urban Ghana and three European cities (Amsterdam, London and Berlin). Comparisons between groups were made using prevalence ratios (PRs) with adjustments for age and education. RESULTS: In rural Ghana, the prevalence of obesity was 1.3 % in men and 8.3 % in women. The prevalence was considerably higher in urban Ghana (men, 6.9 %; PR: 5.26, 95 % CI, 2.04-13.57; women, 33.9 %; PR: 4.11, 3.13-5.40) and even more so in Europe, especially in London (men, 21.4 %; PR: 15.04, 5.98-37.84; women, 54.2 %; PR: 6.63, 5.04-8.72). The prevalence of T2D was low at 3.6 % and 5.5 % in rural Ghanaian men and women, and increased in urban Ghanaians (men, 10.3 %; PR: 3.06; 1.73-5.40; women, 9.2 %; PR: 1.81, 1.25-2.64) and highest in Berlin (men, 15.3 %; PR: 4.47; 2.50-7.98; women, 10.2 %; PR: 2.21, 1.30-3.75). Impaired fasting glycaemia prevalence was comparatively higher only in Amsterdam, and in London, men compared with rural Ghana. CONCLUSION: Our study shows high risks of obesity and T2D among sub-Saharan African populations living in Europe. In Ghana, similarly high prevalence rates were seen in an urban environment, whereas in rural areas, the prevalence of obesity among women is already remarkable. Similar processes underlying the high burden of obesity and T2D following migration may also be at play in sub-Saharan Africa as a consequence of urbanisation.
Smoking prevalence differs by location of residence among Ghanaians in Africa and Europe: The RODAM study
(Public Library of Science, 2017) Brathwaite, R.; Addo, J.; Kunst, A.E.; Agyemang, C.; Owusu-Dabo, E.; De-Graft Aikins, A.; Beune, E.; Meeks, K.; Bahendeka, S.; Mockenhaupt, F.P.; Amoah, S.; Galbete, C.; Schulze, M.B.; Danquah, I.; Smeeth, L.
Background Although the prevalence of smoking is low in Ghana, little is known about the effect of migration on smoking. Comparing Ghanaians living in their country of origin to those living in Europe offers an opportunity to investigate smoking by location of residence and the associations between smoking behaviours and migration-related factors. Methods Data on a relatively homogenous group of Ghanaians living in London (n = 949), Amsterdam (n = 1400), Berlin (n = 543), rural Ghana (n = 973) and urban Ghana (n = 1400) from the cross-sectional RODAM (Research on Obesity & Diabetes in African Migrants) study were used. Age-standardized prevalence rates of smoking by location of residence and factors associated with smoking among Ghanaian men were estimated using prevalence ratios (PR: 95% CIs). Results Current smoking was non-existent among women in rural and urban Ghana and London but was 3.2% and 3.3% in women in Amsterdam and Berlin, respectively. Smoking prevalence was higher in men in Europe (7.8%) than in both rural and urban Ghana (4.8%): PR 1.91: 95% CI 1.27, 2.88, adjusted for age, marital status, education and employment. Factors associated with a higher prevalence of smoking among Ghanaian men included European residence, being divorced or widowed, living alone, Islam religion, infrequent attendance at religious services, assimilation (cultural orientation), and low education. Conclusion Ghanaians living in Europe are more likely to smoke than their counterparts in Ghana, suggesting convergence to European populations, although prevalence rates are still far below those in the host populations. © 2017 Brathwaite et al.

Type 2 diabetes mellitus management among Ghanaian migrants resident in three European countries and their compatriots in rural and urban Ghana – The RODAM study
(Diabetes Research and Clinical Practice, 2018-02) Bijlholt, M.; Meeks, K.A.C.; Beune, E.; Addo, J.; Smeeth, L.; Schulze, M.B.; Danquah, I.; Galbete, C.; De-Graft Aikins, A.; Klipstein-Grobusch, K.et.al.
Aims To compare Type 2 Diabetes Mellitus (T2DM) awareness, treatment and control between Ghanaians resident in Ghana and Europe. Methods Comparisons were made for the 530 participants of the Research on Obesity and Diabetes among African Migrants (RODAM) study with T2DM (25–70 years) living in Amsterdam, Berlin, London, urban Ghana and rural Ghana. We used logistic regression to assess disparities with adjustment for age, sex and education. Results T2DM awareness was 51% in rural Ghana. This was lower than levels in Europe ranging from 73% in London (age-sex adjusted odds ratio (OR) = 2.7; 95%CI = 1.2–6.0) to 79% in Amsterdam (OR = 4.7; 95%CI = 2.3–9.6). T2DM treatment was also lower in rural Ghana (37%) than in urban Ghana (56%; OR = 2.6; 95%CI = 1.3–5.3) and European sites ranging from 67% in London (OR = 3.4; 95%CI = 1.5–7.5) to 73% in Berlin (OR = 6.9; 95%CI = 2.9–16.4). In contrast, T2DM control in rural Ghana (63%) was comparable to Amsterdam and Berlin, but higher than in London (40%; OR = 0.4; 95%CI = 0.2–0.9) and urban Ghana (28%; OR = 0.3; 95%CI = 0.1–0.6). Conclusions Our findings suggest that improved detection and treatment of T2DM in rural Ghana, and improved control for people with diagnosed T2DM in London and urban Ghana warrant prioritization. Further work is needed to understand the factors driving the differences.
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.
