RESUMO

BACKGROUND: Breast cancer is currently the most commonly diagnosed cancer in Ghana and the leading cause of cancer mortality among women. Few published empirical evidence exist on cultural beliefs and perceptions about breast cancer diagnosis and treatment in Ghana. This systematic review sought to map evidence on the socio-cultural beliefs and perceptions influencing the diagnosis and treatment of breast cancer among Ghanaian women. METHODS: This review was conducted following the methodological guideline of Joanna Briggs Institute and reported in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses. The literature search was conducted in PubMed, CINAHL via EBSCOhost, PsycINFO, Web of Science, and Embase. Studies that were conducted on cultural, religious, and spiritual beliefs were included. The included studies were screened by title, abstract, and full text by three reviewers. Data were charted and results were presented in a narrative synthesis form. RESULTS: After the title, abstract, and full-text screening, 15 studies were included. Three categories were identified after the synthesis of the charted data. The categories included: cultural, religious and spiritual beliefs and misconceptions about breast cancer. The cultural beliefs included ancestral punishment and curses from the gods for wrongdoing leading to breast cancer. Spiritual beliefs about breast cancer were attributed to spiritual or supernatural forces. People had the religious belief that breast cancer is a test from God and they resorted to prayers for healing. Some women perceived that breast cancer is caused by spider bites, heredity, extreme stress, trauma, infections, diet, or lifestyle. CONCLUSION: This study adduces evidence of the socio-cultural beliefs that impact on the diagnosis and treatment of breast cancer among women in Ghana. Taking into consideration the diverse cultural and traditional beliefs about breast cancer diagnosis and treatment, there is a compelling need to intensify nationwide public education on breast cancer to clarify the myths and misconceptions about the disease. We recommend the need to incorporate socio-cultural factors influencing breast cancer diagnosis and treatment into breast cancer awareness programs, education, and interventions in Ghana.

RESUMO

BACKGROUND AND PURPOSE: To identify the qualitative and quantitative contributions of conventional risk factors for occurrence of ischemic stroke and its key pathophysiologic subtypes among West Africans. METHODS: The SIREN (Stroke Investigative Research and Educational Network) is a multicenter, case-control study involving 15 sites in Ghana and Nigeria. Cases include adults aged ≥18 years with ischemic stroke who were etiologically subtyped using the A-S-C-O-D classification into atherosclerosis, small-vessel occlusion, cardiac pathology, other causes, and dissection. Controls were age- and gender-matched stroke-free adults. Detailed evaluations for vascular, lifestyle, and psychosocial factors were performed. We used conditional logistic regression to estimate adjusted odds ratios with 95% CI. RESULTS: There were 2431 ischemic stroke case and stroke-free control pairs with respective mean ages of 62.2±14.0 versus 60.9±13.7 years. There were 1024 (42.1%) small vessel occlusions, 427 (17.6%) large-artery atherosclerosis, 258 (10.6%) cardio-embolic, 3 (0.1%) carotid dissections, and 719 (29.6%) undetermined/other causes. The adjusted odds ratio (95% CI) for the 8 dominant risk factors for ischemic stroke were hypertension, 10.34 (6.91-15.45); dyslipidemia, 5.16 (3.78-7.03); diabetes, 3.44 (2.60-4.56); low green vegetable consumption, 1.89 (1.45-2.46); red meat consumption, 1.89 (1.45-2.46); cardiac disease, 1.88 (1.22-2.90); monthly income $100 or more, 1.72 (1.24-2.39); and psychosocial stress, 1.62 (1.18-2.21). Hypertension, dyslipidemia, diabetes were confluent factors shared by small-vessel, large-vessel and cardio-embolic subtypes. Stroke cases and stroke-free controls had a mean of 5.3±1.5 versus 3.2±1.0 adverse cardio-metabolic risk factors respectively (P<0.0001). CONCLUSIONS: Traditional vascular risk factors demonstrate important differential effect sizes with pathophysiologic, clinical and preventative implications on the occurrence of ischemic stroke among indigenous West Africans.

RESUMO

BACKGROUND: Maternal mortality is high in Ghana, averaging 310 maternal deaths per 100,000 live births in 2017. This is partly due to inadequate postnatal care especially among rural communities. Ghana can avert the high maternal deaths if women meet the World Health Organisation's recommended early postnatal care check-up. Despite the association between geographical location and postnatal care utilisation, no study has been done on determinants of postnatal care among rural residents in Ghana. Therefore, this study determined the prevalence and correlates of postnatal care utilization among women in rural Ghana. METHODS: The study utilised women's file of the 2014 Ghana Demographic and Health Survey (GDHS). Following descriptive computation of the prevalence, binary logistic regression was fitted to assess correlates of postnatal care at 95% confidence interval. The results were presented in adjusted odds ratio (AOR). Any AOR less than 1 was interpreted as reduced likelihood of PNC attendance whilst AOR above 1 depicted otherwise. All analyses were done using Stata version 14.0. RESULTS: The study revealed that 74% of the rural women had postnatal care. At the inferential level, women residing in Savanna zone had higher odds of postnatal care compared to those in the Coastal zone [AOR = 1.80, CI = 1.023-3.159], just as among the Guan women as compared to the Akan [AOR = 7.15, CI = 1.602-31.935]. Women who were working were more probable to utilise postnatal care compared to those not working [AOR = 1.45, CI = 1.015-2.060]. Those who considered distance as unproblematic were more likely to utilise postnatal care compared to those who considered distance as problematic [AOR = 1.63, CI = 1.239-2.145]. CONCLUSIONS: The study showed that ethnicity, ecological zone, occupation and distance to health facility predict postnatal care utilisation among rural residents of Ghana. The study points to the need for government to increase maternal healthcare facilities in rural settings in order to reduce the distance covered by women in seeking postnatal care.

RESUMO

ABSTRACT: Although anxiety and depression have been central topics for scholars and clinicians in the United States, few studies have examined their correlates in sub-Saharan Africa and none have examined large urban slums. Using face-to-face interviews in two African cities, we analyze self-reported symptoms of anxiety and depression in a community-based sample (n = 495). Ordinary least squares regression was used to analyze a variety of demographic and social predictors including sex, child-rearing, marital status, education, income, age, and neighborhood for residents of Agbogbloshie (Accra, Ghana) and Kangemi (Nairobi, Kenya). Controlling for other factors, two personal network dimensions were significant. Total network size is positively associated with symptoms of anxiety and depression in Kenya but not in Ghana. However, one factor was predictive of symptoms of anxiety and depression in both locations: the reported percentage of ties with older persons. Higher levels of anxiety and depression are associated with a larger share of older individuals in one's personal network.

RESUMO

OBJECTIVE: In the advent of rapid urbanisation, migration and epidemiological transition, the extent to which serum uric acid (sUA) affects cardiovascular disease (CVD) risk among Africans is not well understood. We assessed differences in sUA levels and associations with CVD risk among migrant Ghanaians in Europe and non-migrant Ghanaians in rural and urban Ghana. METHODS: Baseline data from 633 rural, 916 urban and 2315 migrant participants (40-70 years) from the cross-sectional RODAM study were analysed. Hyperuricaemia was defined as sUA >7 mg/dl in men and >6 mg/dl in women. The 10-year risk of atherosclerotic cardiovascular disease (ASCVD) was calculated using the American College of Cardiology (ACC)/American Heart Association (AHA) risk score which takes into account ethnic minority populations. High CVD risk was defined as ASCVD risk scores ≥7.5%. Logistic regressions were used to assess associations between hyperuricaemia and CVD risk. RESULTS: Prevalence for hyperuricaemia in rural, urban and migrant participants was 17.4%, 19.1% and 31.7% for men, and 15.9%, 18.2% and 33.2% for women, respectively. Hyperuricaemia was positively associated with elevated CVD risk among rural residents (adjusted OR for men 3.28, 95% CI: 1.21-8.96, 6.36, 95% CI: 2.98-13.56 for women), urban residents (1.12, 95% CI: 0.45-2.81 for men, 2.11, 95% CI: 1.26-3.52 for women) and migrants (1.73, 95% CI: 1.01-2.96 for men, 4.61, 95% CI: 3.05-6.97 for women). CONCLUSION: Our study shows variations of sUA levels in different African contexts. Hyperuricaemia is associated with elevated 10-year CVD risk in both migrants and non-migrants. Further studies should identify factors driving associations between sUA and CVD risk in Africans.


OBJECTIF: Avec l'avènement de l'urbanisation rapide, de la migration et de la transition épidémiologique, la mesure dans laquelle l'acide urique sérique (AUs) affecte le risque de maladie cardiovasculaire (MCV) chez les Africains n'est pas bien comprise. Nous avons évalué les différences dans les niveaux d'AUs et les associations avec le risque de MCV chez les ghanéens migrants en Europe et non migrants dans les zones rurales et urbaines du Ghana. MÉTHODES: Les données de base de 633 participants ruraux, 916 urbains et 2.315 migrants, de 40 à 70 ans de l'étude transversale RODAM ont été analysées. L'hyperuricémie a été définie comme une AUs > 7 mg/dl chez les hommes et >6 mg/dl chez les femmes. Le risque sur 10 ans de MCV athérosclérosique (MCVAS) a été calculé en utilisant le score de risque de l'American College of Cardiology (ACC)/American Heart Association (AHA) qui prend en compte les populations des minorités ethniques. Un risque de MCV élevé était défini comme un score de risque MCVAS ≥7,5%. Des régressions logistiques ont été utilisées pour évaluer les associations entre l'hyperuricémie et le risque de MCV. RÉSULTATS: La prévalence de l'hyperuricémie chez les participants ruraux, urbains et migrants était de 17,4% ; 19,1% et 31,7% pour les hommes et 15,9%, 18,2% et 33,2% pour les femmes, respectivement. L'hyperuricémie était positivement associée à un risque élevé de MCV chez les résidents ruraux (OR ajusté 3,28 ; IC95%: 1,21-8,96 pour les hommes, 6,36, IC95%: 2,98-13,56 pour les femmes), les résidents urbains (1,12 ; IC95%: 0,45-2,81 pour les hommes, 2,11 ; IC95%: 1,26-3,52 pour les femmes) et les migrants (1,73 ; IC95%: 1,01-2,96 pour les hommes, 4,61 ; IC95%: 3,05-6,97 pour les femmes). CONCLUSION: Notre étude montre des variations des niveaux d'AUs dans différents contextes africains. L'hyperuricémie est associée à un risque élevé de MCV sur 10 ans chez les migrants et les non-migrants. Des études plus poussées devraient identifier les facteurs à l'origine des associations entre le risque d'AUs et de MCV chez les africains.

RESUMO

BACKGROUND: Since the National Malaria Elimination Action Plan was launched in China in 2010, local malaria transmission has decreased rapidly. Zero indigenous cases were reported since 2017. However, after 2010, the proportion of imported cases in China increased from 45.7% in 2010 to 99.9% in 2016, and almost all provinces of China have reported imported cases in recent years. Prevention of the reintroduction of malaria into China is crucial for the maintenance of its malaria-free status. Hence, it is of utmost importance to correctly identify the source of malaria infections within the country. CASE INTRODUCTION AND RESPONSE: In 2016 and 2017, three laboratory-confirmed cases of malaria caused by Plasmodium falciparum were identified in patients with no previous travel history to endemic areas were reported in Jiangsu Province, China, where malaria due to P. falciparum was eliminated about 30 years ago. These were diagnosed after 41, 31 and 39 days of seeking treatment, respectively, and all of them had received blood transfusions. Further investigations indicated that two of the cases had received blood from foreign students (from Indonesia and Ghana), and the other had received blood from an individual who had worked in Equatorial Guinea. All three blood donors were traced, and found to be carrying asymptomatic P. falciparum infections by microscopic examination and PCR. Furthermore, five polymorphic microsatellite markers (C1M4, C4M62, C13M13, C14M17, and C13M63) were typed and used to link parasites from the donors with those of the transfusion-receiving patients. CONCLUSIONS: Three transfusion-transmitted malaria cases were identified in China, all of which were due to the transfusion of blood donated by individuals who had contracted malaria outside the country. These cases can provide a reference for those faced with similar challenges in malaria case identification and classification in other regions. In addition, a stricter screening policy including the use of appropriate detection methods for malaria parasites should be developed and adopted for blood donation in regions undergoing malaria elimination.

RESUMO

In this study, 268 samples for unrelated males belonging to the five major human subpopulation groups in Ghana (Akan, Ewe, Mole-Dagbon, Ga-Dangme and Guang) were genetically characterised for 23 Y chromosome short tandem repeat (STR) loci using the Powerplex® Y23 STR kit. A total of 263 complete haplotypes were recorded of which 258 were unique. The haplotype diversity, discriminating capacity and match probability for the pooled population data were 0.9998, 0.9627 and 0.0039, respectively. The pairwise genetic distance (RST) for the Ghanaian datasets and other reference populations deposited in the Y-STR Haplotype Reference Database (YHRD) were estimated and mapped using multidimensional scaling (MDS) plot. The Guang and Ewe were significantly different from the Akan, Mole-Dagbon and Ga-Dangme. However, the five Ghanaian datasets were all plotted close together with other African populations in the MDS data mapping.

RESUMO

BACKGROUND: The Dutch multi-ethnic Healthy Life in an Urban Setting study recently showed that alcohol consumption was lower in ethnic minority groups than those of Dutch origin, but that binge drinking in drinkers of Turkish and Moroccan origin was relatively high. The aim of the current study is to examine factors that may contribute to the differences in drinking patterns and how they relate to the relationship between drinking patterns and alcohol dependence (AD) across ethnic groups. METHODS: The rate of last year alcohol use, alcohol use patterns and AD was assessed in 4,635 Dutch, 4,317 Moroccan, 4,036 Turkish, 2,459 Ghanaian, 4,426 African Surinamese and 3,357 South-Asian Surinamese participants (both men and women) born in Amsterdam, the Netherlands. RESULTS: Compared to the Dutch, the prevalence of (regular) drinking is substantially lower in all ethnic minority groups and regular drinkers among most ethnic minority groups have a lower adjusted risk to develop binge drinking and AD than the Dutch. For the prevalence of regular drinking, the ethnic differences are bigger than for the prevalence of current drinking. However, regular drinkers of Moroccan origin have a risk similar to the Dutch to develop binge drinking and AD; a finding that could not be explained by group differences in age, sex, religiosity, perceived discrimination, depression or guilt feelings about drinking. DISCUSSION: The prevalence data show that current drinking is lower and that regular drinking is much lower in ethnic minorities and - with the exception of those of Moroccan origin - ethnic minority regular drinkers also have a significant lower risk to develop binge drinking or AD than regular drinkers of Dutch origin. This implies that the magnitude of problematic alcohol use is substantially smaller in ethnic minorities than in the ethnic Dutch population of Amsterdam. Unfortunately, no explanation was found for the special risk situation of regular drinkers of Moroccan origin.

RESUMO

PURPOSE: Psychosocial stress is associated with obesity in some populations, but it is unclear whether the association is related to migration. This study explored associations between psychosocial stress and obesity among Ghanaian migrants in Europe and non-migrant Ghanaians in Ghana. METHODS: Cross-sectional data from the RODAM study were used, including 5898 Ghanaians residing in Germany, the UK, the Netherlands, rural Ghana, and urban Ghana. Perceived discrimination, negative life events and stress at work or at home were examined in relation to body mass index (BMI) and waist circumference (WC). Linear regression analyses were performed separately for migrants and non-migrants stratified by sex. RESULTS: Perceived discrimination was not associated with BMI and WC in both migrants and non-migrants. However, negative life events were positively associated with BMI (ß = 0.78, 95% CI 0.34-1.22) and WC (ß = 1.96, 95% CI 0.79-3.12) among male Ghanaian migrants. Similarly, stress at work or at home was positively associated with BMI (ß = 0.28, 95% CI 0.00-0.56) and WC (ß = 0.84, 95% CI 0.05-1.63) among male Ghanaian migrants. Among non-migrant Ghanaians, in contrast, stress at work or at home was inversely associated with BMI and WC in both males (ß = - 0.66, 95% CI - 1.03 to - 0.28; ß = - 1.71 95% CI - 2.69 to - 0.73, respectively) and females (ß = - 0.81, 95% CI - 1.20 to - 0.42; ß = - 1.46, 95% CI - 2.30 to - 0.61, respectively). CONCLUSIONS: Negative life events and stress at work or at home are associated with increased body weight among male Ghanaians in European settings, whereas stress at work or at home is associated with reduced body weight among Ghanaians in Ghana. More work is needed to understand the underlying factors driving these differential associations to assist prevention efforts.

RESUMO

Objective: Ethnic minorities report different levels of drinking and smoking and higher rates of depression compared to native populations. In this study we aimed to investigate in six ethnic groups whether tobacco and alcohol use were associated with depressive symptoms, which are more prevalent in ethnic minorities.Methods: Cross-sectional data from the multi-ethnic Healthy Life in an Urban Setting (HELIUS) study sample (N = 22,471) was used, comprising 4,580 native Dutch participants which were compared with participants from five ethnic minority groups (3,259 South Asian Surinamese, 4,292 African Surinamese, 2,262 Ghanaian, 3,891 Turkish, and 4,187 Moroccan).Results: Alcohol misuse was positively associated with depressed mood in all ethnic groups except for the Dutch and the Ghanaians. Nicotine dependence was positively associated with depressed mood in all ethnic groups except for the Ghanaian group.Conclusions: Alcohol misuse and nicotine dependence were significantly associated with depressed mood in most but not all ethnic groups and especially in men. However, across all groups the contribution of alcohol misuse and nicotine dependence to depressed mood was small. Prospective multi-ethnic studies should confirm whether the relations are causal and elucidate their direction.

RESUMO

OBJECTIVE: To investigate subtype-specific risk of germline alleles associated with triple negative breast cancer (TNBC) in African ancestry populations. BACKGROUND: Breast cancer (BC) mortality is higher in African American (AA) compared to White American (WA) women; this disparity is partly explained by 2-fold higher TNBC incidence. METHODS: We used a surgically maintained biospecimen cohort of 2884 BC cases. Subsets of the total (760 AA; 962 WA; 910 West African/Ghanaian; 252 East African/Ethiopian) were analyzed for genotypes of candidate alleles. A subset of 417 healthy controls were also genotyped, to measure associations with overall BC risk and TNBC. RESULTS: TNBC frequency was highest in Ghanaian and AA cases (49% and 44% respectively; P < 0.0001) and lowest in Ethiopian and WA cases (17% and 24% respectively; P < 0.0001). TNBC cases had higher West African ancestry than non-TNBC (P < 0.0001). Frequency of the Duffy-null allele (rs2814778; an African ancestral variant adopted under selective pressure as protection against malaria) was associated with TNBC-specific risk (P < 0.0001), quantified West African Ancestry (P < 0.0001) and was more common in AA, Ghanaians, and TNBC cases. Additionally, rs4849887 was significantly associated with overall BC risk, and both rs2363956 and rs13000023 were associated with TNBC-specific risk, although none as strongly as the Duffy-null variant. CONCLUSIONS: West African ancestry is strongly correlated with TNBC status, as well as germline variants related to BC risk. The Duffy-null allele was associated with TNBC risk in our cohort.

RESUMO

BACKGROUND: Several viruses have been described as causes of acquired inflammatory myopathies; however, the mechanisms by which they cause muscle disease are still unclear. The aim of this study was to describe the laboratory features of benign acute myositis in a small case series. METHODS: A detailed pathological and serological analysis was performed in five African migrants who developed an acute viral myositis complicated by rhabdomyolysis. RESULTS: Muscle biopsies clearly documented an inflammatory myopathy with histological features similar to polymyositis including CD8+ T cells surrounding and invading nonnecrotic muscle fibers, CD68+ macrophages and major histocompatibility complex class I antigen upregulation. In addition, positivity for myositis-specific antibodies (MSA), in particular anti-aminoacyl tRNA synthetases, was found in the serum of two patients. CONCLUSIONS: Our study demonstrated that T-cell mediated injury occurs in muscle of patients with acute viral myositis, and that MSA may be present in the serum of these patients.

RESUMO

A 22-year-old HIV-negative man from Ghana was diagnosed with severe hemophagocytic lymphohistiocytosis (HLH) induced by multiorgan tuberculosis with peritoneal, hepatic, pericardial, myocardial, pleural, pulmonary, and bone manifestation. His body mass index was 12.9 m2/kg. Bioptic material of a peritoneal biopsy grew M. tuberculosis, sensitive to all first-line antituberculous drugs. HLH resolved with antituberculous therapy, without additional anti-inflammatory therapy being given. The initial CT scan of his brain was normal. After 5 months of antituberculous treatment, he developed a paralysis of the left arm. A cerebral MRT showed ring-enhanced lesions. Blood cultures and lumbar puncture revealed Cryptococcus neoformans var. grubi. The HIV test was repeatedly negative. Antituberculous treatment was continued for a total of 9 months, and additional treatment with antifungal therapy was established. He recovered fully after 14 months of antifungal treatment.

RESUMO

BACKGROUND AND AIMS: Cardiovascular disease (CVD) risk factors may occur among a substantial proportion of normal weight individuals, particularly among some ethnic minorities. It is unknown how many of these individuals would be missed by commonly applied eligibility criteria for cardiovascular risk screening. Thus, we aim to determine cardiovascular risk and eligibility for cardiovascular risk screening among normal weight individuals of different ethnic backgrounds. METHODS AND RESULTS: Using the HELIUS study (Amsterdam, The Netherlands), we determined cardiovascular risk among 6910 normal weight individuals of Dutch, South-Asian Surinamese, African Surinamese, Ghanaian, Moroccan and Turkish background. High cardiovascular risk was approximated by high metabolic risk based on blood pressure, HDL, triglycerides and fasting glucose. Eligibility criteria for screening were derived from Dutch CVD prevention guidelines and include age ≥ 50 y, family history of CVD, or current smoking. Ethnic group comparisons were made using logistic regression. Age-adjusted proportions of high metabolic risk ranged from 12.6% to 38.4% (men) and from 2.7% to 11.5% (women). This prevalence was higher among most ethnic minorities than the Dutch, especially among women. For most ethnic groups, 79.9%-86.7% of individuals with high metabolic risk were eligible for cardiovascular risk screening. Exceptions were Ghanaian women (58.8%), Moroccan men (70.9%) and Moroccan women (45.0%), although age-adjusted proportions did not differ between groups. CONCLUSION: Even among normal weight individuals, high cardiovascular metabolic risk is more common among ethnic minorities than among the majority population. Regardless of ethnicity, most normal weight individuals with increased risk are eligible for cardiovascular risk screening.

RESUMO

Parental autonomy support has been related to positive adolescent outcomes, however, its relation to outcomes in collectivist cultural groups is unclear. This study examined relations of specific autonomy supportive behaviors and outcomes among 401 adolescents (Mage  = 12.87) from the United States (N = 245) and collectivist-oriented Ghana (N = 156). It also examined whether adolescents' self-construals moderated the relations of specific types of autonomy support with outcomes. Factor analyses indicated two types of autonomy support: perspective taking/open exchange and allowance of decision making/choice. In both countries, perspective taking/open exchange predicted positive outcomes, but decision making/choice only did so in the United States. With regard to moderation, the more independent adolescents' self-construals, the stronger the relations of decision making/choice to parental controllingness and school engagement.

RESUMO

BACKGROUND: Metabolic syndrome (MetSyn) is an important risk factor for cardiovascular diseases and type 2 diabetes. It is unknown whether the MetSyn prevalence differs within a homogenous population residing in different settings in Africa and Europe. We therefore assessed the prevalence of MetSyn among Ghanaians living in rural- and urban-Ghana and Ghanaian migrants living in Europe. METHODS: We used data from the cross-sectional multi-centre RODAM study that was conducted among Ghanaian adults aged 25-70 years residing in rural- and urban-Ghana and in London, Amsterdam and Berlin (n = 5659). MetSyn was defined according to the 2009 harmonized definition. Geographical locations were compared using age-standardized prevalence rates, and prevalence ratios (PRs), adjusted for age, education, physical activity, and smoking and stratified for sex. RESULTS: In men, the age-standardized prevalence of MetSyn was 8.3% in rural Ghana and showed a positive gradient through urban Ghana (23.6%, adjusted PR = 1.85, 95% confidence interval 1.17-2.92) to Europe, with the highest prevalence in Amsterdam (31.4%; PR = 4.45, 2.94-6.75). In women, there was a rural-to-urban gradient in age-standardized MetSyn prevalence (rural Ghana 25%, urban Ghana 34.4%, PR = 1.38, 1.13-1.68), but small differences in MetSyn prevalence between urban-Ghanaian and European-Ghanaian women (Amsterdam 38.4%; London 38.2%). CONCLUSION: MetSyn is highly prevalent in Ghana as well as in Ghanaian migrants in Europe. To assist prevention efforts, further research is needed to understand the mechanisms driving the geographical differences in MetSyn prevalence between migrant and non-migrant Ghanaians.

RESUMO

In the UK, ethnic minority groups tend to have higher levels of poverty than the white British population and therefore may be at high risk of food insecurity. Ghanaians, living in Ghana or as migrants are thought to have a high level of social support in their communities, but the role of this resource in relation to food security is unknown. We explored participants' perceptions of social and economic factors influencing food security among Ghanaian migrants in Greater Manchester. Participants aged ≥25 years (n = 31) of Ghanaian ancestry living in Greater Manchester were interviewed using a semi-structured interview guide developed by the researchers. Participants varied in socioeconomic status (SES), gender and migration status. Interviews were transcribed verbatim and analysed thematically using a framework approach. Participants offered similar accounts of the social and economic factors influencing food security. Accounts were based on participants' perceptions and/or personal experiences of food insecurity within the community. Participants indicated that they and their fellow Ghanaians can 'manage' even when they described quite challenging food access environments. This has negative implications on their food choices in the UK. Participants reported food insecure households may be reluctant to make use of food banks for fear of 'gossip' and 'pride'. Paradoxically, this reluctance does not extend to close network. Many participants described the church and other social groups as a trusted base in which people operate; support given through these channels is more acceptable than through the 'official context'. Government assisted food banks could partner with the social groups within this community given that these are more trusted. Keywords: food insecurity; food choice; social networks; Ghanaians; healthy eating; migrants.

RESUMO

BACKGROUND: This paper explored the health beliefs and behaviours of families towards the health needs of children with intellectual and developmental disabilities (IDD) in Accra, Ghana. The aim was to inform health promotion strategies for the children and their families. METHOD: Twenty-two parents of children with IDD participated in this study. Semi-structured interviews were the primary means of data collection. The interviews were analysed using constant comparison. RESULTS: The signs that alerted the parents that the children might be ill included high temperature, vomiting and excessive sleep. The parents explained that some children expressed feelings of ill-health through verbal or non-verbal communication. Most of the parents self-prescribed medication for the children or waited for symptoms to persist for a while before accessing health care because they experienced difficulties managing the behavioural challenges associated with the IDD of the children in public and attitudinal barriers when accessing health care. The parents did not often patronise health facilities in their neighbourhoods due to private health insurance requirements for accessing care at designated facilities, poor confidence in neighbourhood facilities and long-term established relationships with facilities elsewhere. Further, many parents did not patronise religious interventions for the children. However, some parents explained that in addition to seeking medical care to address the physical symptoms of the children's disabilities and/or illnesses, they sought religious interventions because they believed that there could be a spiritual dimension to the situation. CONCLUSION: The findings highlight key areas to address in health promotion for children with IDD and their families in Accra, Ghana.

RESUMO

BACKGROUND: Herbal medicine has become the panacea for many rural pregnant women in Ghana despite the modern western antenatal care which has developed in most parts of the country. To our knowledge, previous studies investigating herbal medicine use have primarily reported general attitudes and perceptions of use, overlooking the standpoint of pregnant women and their attitudes, and utilisation of herbal medicine in Ghana. Knowledge of herbal medicine use among rural pregnant women and the potential side effects of many herbs in pregnancy are therefore limited in the country; this qualitative study attempts to address this gap by exploring the perceptions of herbal medicine usage among pregnant women in rural Ghana. METHODS: A sample of 30, conveniently selected pregnant women, were involved in this study from April 11 to June 22, 2017. Data from three different focus group discussions were thematically analysed and presented based on an a posteriori inductive reduction approach. RESULTS: The main findings were that pregnant women used herbal medicine, most commonly ginger, peppermint, thyme, chamomile, aniseeds, green tea, tealeaf, raspberry, and echinacea leaf consistently throughout the three trimesters of pregnancy. Cultural norms and health beliefs in the form of personal philosophies, desire to manage one's own health, illness perceptions, and a holistic healing approach were ascribed to the widespread use of herbs. CONCLUSION: We recommend public education and awareness on disclosure of herbal medicine use to medical practitioners among pregnant women.

RESUMO

BACKGROUND: The use of traditional/alternative medicine for health care in Africa has been examined for various conditions. However, there is limited research about traditional/alternative health care for intellectual disability. The present authors explored the explanatory models (EMs) of intellectual disability held by traditional/faith healers in Ghana. METHODS: Using a case vignette, the present authors conducted semi-structured interviews with 36 traditional/faith healers in Accra, Ghana. Using the EMs of illness framework as a guide, participants were asked questions to examine their beliefs about the nature, causes, course and recommended treatment of intellectual disability. RESULTS: The healers' causal explanations included maternal negligence during pregnancy and spiritual factors. They also believed that intellectual disability was a congenital, lifelong condition which could not be cured. CONCLUSIONS: Unlike other conditions which traditional healers claimed to cure, participants admitted that intellectual disability was not curable. The present authors suggest that the findings highlight opportunities that exist for collaboration between biomedicine and traditional medicine.
