Beliefs about health
Health was described in terms of individual factors. The content was mainly focused on well-being, expressed in terms of freedom from disease and bodily pain, and being strong and fit
...free of disease...looking after oneself well... Involves a feeling of well-being with no bodily pain. (6)
...to be strong and fit...someone is strong without any illness. (2)
Measures used in order to feel well and experience good health were also described as individually related factors, and the two subcategories of lifestyle factors and looking after oneself emerged. Lifestyle factors mainly included conforming to the correct diet, but some others mentioned exercise. Hygiene, personal and environmental, compliance with drugs and diabetic diet, and avoiding factors with negative influence on health such as injuries, were included in looking after oneself:
I make sure that I get good body-building foods, maintain good body hygiene, make sure that my environment is clean and follow doctor's instructions on drug taking. (1)
Respondents predominantly talked about individual factors in terms of compliance with diet, drugs and following doctor's instructions and having check-ups as being important for their health as far as DM was concerned. There were also some who talked about lifestyle factors such as regular exercise and maintenance of good personal hygiene.
All respondents, with the exception of one, considered instrumental tangible support from their family members. Assistance mentioned was mainly in terms of material support with provision of money to buy food and drugs, equipment for self-monitoring of blood glucose (SMBG), and help with preparation of food and supervision of meals. Acceptance of a sick person as a diabetic and psychological support to live positively were also mentioned:
...help me to live positively, help with different things...provide money to buy medications and right diet. (10)
...understand my condition so that they will be able to assist when I fall sick. (11)
Health professionals were considered important for health mainly because they give information support about the disease, food preparation and medications. Many also discussed a combination of material and social support concerning health maintenance, expressed as control of the disease and screening for potential health problems, and counselling, e.g. encouragement and reminders to maintain good health. Finally, a few talked about emotional support in understanding the needs of a person with DM:
...give information...teach me those things that I am supposed to and not supposed to do...give more advice on food, especially alternatives that I can eat...inform on how to give injections. (1)
...these people understand me and my needs as a diabetic patient. (6)
...give advice on how to look after myself, food preparation and taking of drugs...monitor my blood sugar levels regularly (3)
Concerning factors harmful to health, it was mainly social factors in terms of a poor economic situation resulting in lack of food, money, expensive or unavailable drugs, and over-working that were mentioned. Some stated social relations such as being single or divorced and others discussed other diseases. One person talked about a harmful lifestyle with smoking.
...everything is just too expensive these days... (20)
...many factors...the way I am living these days...lack of food, lack of money to buy drugs and to come for reviews (1)
Awareness of bodily signs was the predominant way to know whether health became worse, e.g. mainly general body weakness or tiredness or passing too much urine, but also headache, loss of appetite, and drinking too much water were stated. Some talked about check-ups at hospital as a possibility to monitor health status:
...some symptoms that are noticed, for example passing lots of urine, feeling tired and having headaches. (10)
...can only tell when I come for reviews at the hospital...(1)
When discussing the influence of economy on health, all respondents unanimously expressed negative effects as they were unable to buy food or drugs or to go for reviews at the hospital.
...the present situation has become too hard to buy medications and food...I minimize coming for reviews because the situation forces me to. (1)
Measures claimed to improve health when diagnosed with DM were mainly prayers or a healing power (supernatural factors) and household remedies such as various herbs (garlic, zumbani (green leaves from a plant), teas, aloe) or cough remedies, paracetamol etc. (natural factors). However, there was also a group of people who said they had never used nature cure medicine or were not allowed by their church to use them. More than half of the respondents had been in contact with the diabetes association, to share information and disease experience with others, and there they received support and assistance in problem solving from experts, but some did not know about its existence (social factors):
...prayers are useful and can have a healing power (6)
...natural herbs, garlic to lower blood pressure and salicylate ointment for painful joints (17)
...people with diabetes come (to the diabetes association) and share information and ideas concerning solutions to their problems...get assistance from experts and health practitioners (3).
To maintain health and prevent complications related to DM, all respondents brought up individual factors. The majority talked about compliance, mainly in terms of diet with reduction of sugar intake and avoidance of overeating, but also about medication and check-ups. Avoiding stress and working hard to earn a living were also stated.
...avoid foods that contain too much sugar,...live a life that conforms to one with diabetes, go for regular check-ups, test my blood sugar levels and take pills and injections on time. (10)
Beliefs about illness
All respondents, except one, had not suspected DM when they fell ill with the disease. Most described how they felt they were going to die, others suspected witchcraft and a few suspected other diseases such as malaria, HIV and AIDS. Several symptoms, for example, drinking a lot of water, passing a lot of urine, feeling of dying, general body weakness and being tired had been experienced. Most went to the professional sector, to see a physician, either at clinics, doctors' surgeries or hospitals, while a few sought help from the popular sector, such as husbands, wives or friends, and two went to the folk sector to see n'angas (traditional healers).
...experiencing a feeling of tiredness, loss of weight, dryness of the mouth and passing lots of urine...I got confused because I failed to understand what was happening....feeling of dying...went to seek advice from a sister-in-law (a nurse)...tested my urine...then taken to a private doctor. (9)
...started by excess loss of weight, drinking large amounts of water...and I thought I had been bewitched...was taken to a n'anga but I got worse...Taken to the doctor...later referred for admission to hospital. (5)
DM was perceived by some, and expressed in answers to open-ended questions, as being caused by heredity (individual factors), other drugs such as anti-hypertensives (natural factors) or wrong food (individual factors), while others related it to problems of the pancreas (individual factors), and some didn't know (see Table
2). When a list of potential causes of DM was presented, most talked about individual factors such as heredity, wrong diet and obesity, inactivity and diseases of the pancreas. Supernatural factors such as fate or the influence of God, witches or evil spirits were added as well as social factors such as stress. Thus, a mixture of causes were mentioned, although predominantly focused on individual factors such as heredity, overweight and wrong dietary habits in combination with supernatural factors lying outside the individual's own control in terms of fate, punishment from God and witchcraft.
When discussing what happens in the body when one gets DM and the function of the pancreas, in general limited knowledge was demonstrated. Most knew about the function of insulin in reducing blood sugar.
The majority of respondents perceived DM to be lifelong and persisting until death and only one person indicated that it could be controlled.
Knowledge about the action of drugs was limited. Most of the respondents were treated with oral agents and the others with insulin. Those who discussed the main effects of treatment in general stated regulation of blood sugar levels and a few talked about correction of eye sight or thirst.
Major problems as a consequence of DM were reported by about half of the studied group. These consisted of varying physical matters such as 'reduced vision', 'coma', 'swollen joints', and 'difficult deliveries', financial problems in terms of 'too expensive drugs' and in one case 'taking too frequent meals' (individual and social factors).
All respondents, with the exception of three persons, expressed fears related to DM because of different complications, mainly coma but also loss of sight, heart failure, stroke and diabetic foot ulcers, and in one case inability to buy drugs because of high costs (individual and social factors).
Most respondents experienced problems in their contact with health care staff who checked their DM. These were related to delays by doctors, not coming on time or having lack of time to explain things, and delays at the pharmacy or dispensary.
...doctors start their clinics late...see a lot of people at a time and are always in a hurry, so one does not get enough time to ask questions...delays at pharmacy...something has to be done. (10)
Self-care and care-seeking pattern
Respondents spoke of being informed about the importance of reviewing the progress of DM by regular check-ups of sugar levels and drug doses by a physician.
About half of the group had been informed about foot care but with a limited content:
...advised that diabetic wounds take a long time to heal...should keep blood sugar low, avoid injuries and keep feet dry. (6)
Most respondents reported that advice had been given concerning the importance of SMBG in terms of using bodily signs, e.g. passing urine, drinking a lot, feeling sleepy, bitterness in the mouth etc., to know about blood glucose to avoid sudden changes in sugar and minimizing complications such as coma. Only one had the equipment for monitoring their blood glucose at home. Some had not received any advice at all.
When discussing recommendations for diet, most cited the importance of reducing the intake of carbohydrates, mainly sugar, and increasing the intake of vegetables. A few talked about reduction of fat and regular meals. Four persons had received initial information from a dietician.
Food without much sugar, less carbohydrates and lots of fruit and green vegetables. (10)
...not to eat sugary foods, take fats in small amounts, have snacks in between. (14)
As regards advice about exercise, most had been informed of the importance of regular exercise: 'to exercise regularly...to lose weight by walking or jogging' (4) and 'drugs to be taken as directed'(16).
All respondents in general reported they mainly followed advice received, as it prolongs life. Reasons for not following advice could be:
...I try but it's rather difficult...don't have money to buy drugs and necessary monitoring equipment. (7)
When discussing different common health problems related to DM, such as hyperglycaemia, repeated episodes of hypoglycaemia, gastrointestinal infection, common cold and pharyngitis, urinary infection, problems with the feet (crawling, burning, decreased sensitivity), spasm in the calf, hypertension, and albuminuria, most respondents had used self-care measures related to the individual sphere (e.g. changes of food intake, rest, wait-and-see), nature (medications or herbs) or the supernatural sphere (mainly prayers, sometimes holy water). When necessary, help was sought from the professional sector, mainly from doctors and in some cases from nurses at a hospital based clinic. Most respondents indicated difficulties in identifying the causes of the problems and said they were unsure or gave a variety of causes but often included an association with DM.
...I think it was because of my diabetes...I used herbal leaves to rub over painful joints, smoked the herbs...also prayed for relief of my body pains...it worked. In the second instance I visited my doctor. (8)
When discussing the occurrence of wounds on the feet, a pattern was evident where most respondents had sought help from the professional sector at hospitals (social factors) and related the problem to injuries.
Methods
A consecutive sampling procedure was used, giving all men and women visiting the clinic the same opportunity to participate in the study. The studied group mainly comprised persons with a secondary level of education, of working age, coming from both urban and rural areas of the country. Zimbabwe is considered to have one of Africa's best educational systems and thus the population is relatively well-educated [
20]. Primary school is formally mandatory and followed by further education in secondary school. According to reports by UNESCO, four out of ten children started secondary school in 2002. About two thirds of the population live in rural areas but there is extensive migration into the bigger cities. Thus, the studied group appeared to represent the general population of Zimbabwe. Gender is not problematized in this first explorative step but will be further elaborated in an extended study.
Interviews were held mainly in Shona (n = 18) but also in English (n = 3), which are two of the three official languages in Zimbabwe [
20]. Some 70-80% of the population belong to the Shona-speaking group and this is spoken in everyday life by the majority, but many also speak English, particularly in the cities. Ndebele is the third language, spoken in the south and western part of the country. The site where the study was carried out is situated in the central part of Zimbabwe.
In order to minimize the influence of different languages, the interview guide was pilot-tested in both languages, the interviews were conducted by a bilingual nurse, and the participants were offered a choice as to the language they preferred to use during the interview.
Triangulation of data by using different methods to gain knowledge by open-ended and closed questions, with probing for detailed beliefs and knowledge, made an in-depth understanding possible [
19] and possibly also revealed more or less unconscious beliefs and thus avoided collecting the frequently criticized superficial knowledge obtained by using only structured interviews or questionnaires [
24].
Results from qualitative studies might be seen as limited as regards the possibility of generalizing data from them [
19]. However, the aim of the present study was to explore beliefs in a group of people diagnosed with type 2 DM and the focus was on disclosure of different perspectives and not on finding results generalizable to the whole population. Carefully collected and analysed qualitative data are transferable to other populations, or contexts similar in characteristics [
19].
Results
In this study beliefs about health were expressed from a pathogenic point of view [
25] similar to what has been found in previous studies concerning beliefs about health and illness in Ugandan men and women [
11] and in migrants with DM living in Sweden [
9,
10,
18]. Economic factors were emphasized as a major influence on health and the ability to comply with advice received about the management of DM. Underlying living conditions might thus be a barrier to adequate management of the disease, as well as an underlying cause to it [
26], and need to be considered in diabetes care. A conflict between willingness to comply and ability to comply was demonstrated, and this is related to the current economic crisis in Zimbabwe. The crisis started in the late 1990s and has entailed a social deterioration with increasing poverty, poorer public health, lack of food etc [
20]. In 2006 about 80% of the population of working age were unemployed, 70-80% of the Zimbabweans are estimated to live in poverty, and about 4.3 million people were in need of food aid according to the United Nations World Food Programme in 2005. Similar findings have been shown among Ugandans [
11]. The diabetes epidemic, particularly its distribution, is argued [
26] to be produced by poverty. The cumulative effects of structural constraints on healthy lifestyles and lack of a right to adequate medical care, are results of poverty leading to diabetes and its complications, and to disparities among social groups. However, the differences are avoidable, unjust and unnecessary. The roots of the pandemia lie in inequalities in social power and the solutions required are structural.
Beliefs about health and illness were mainly related to factors in the individual combined with factors in nature and the supernatural sphere as regards ways to improve health or measures to restore health after having problems or being ill. Health care was consulted to a limited extent and with few exceptions in the professional sector when needed.
Health-related behaviour thus did not correspond to what has previously been described in persons of non-western origin [
22,
23]. Non-westerners have been described as focusing on the social or supernatural spheres to explain illness causation, and contacting family or friends in the popular sector first when in need of care and then turning to traditional healers in the folk sector, in contrast to westerners who emphasize factors in the individual or nature and mainly consult the professional health care sector in the event of problems. As in previous investigations [
9‐
11,
18], the results do not correspond to the theoretical models [
22,
23] chosen for analysing data. The differences might be explained by, for example, dissimilarities in health care systems in different countries and restricted empirical testing of explanatory models [
9,
10], which further emphasizes the need to avoid crude generalizations about people's beliefs and instead to probe for and verify the individual's own perspective. However, the models do play an important role as a framework when searching for different perspectives.
Findings from open-ended questions showed that many respondents were unsure of the cause of DM, while some stated biomedical explanations (antihypertensive drugs, pancreatic disease). When adding results from discussions of a list of potential causes, respondents mainly mentioned individual factors such as obesity and unhealthy diet but also supernatural causes such as fate, punishment from God, spirits etc. lying outside the person's own control. Thus, the pattern appears to be more similar to what has been found in Europeans citing medically oriented causes, e.g. heredity and obesity [
9,
10,
17,
18] but also a fatalistic view discussing factors beyond a person's own control such as fate, the will of God etc. (an external locus of control; shown in Ugandans [
11], North Africans [
17] and Middle-Easterners [
9,
10]. Thus, a mixture of explanations was found that might be related to limited knowledge about DM, also evident in discussions concerning the pathophysiology of DM, action of drugs, and many were unable to identify the disease at the onset and suspected other diseases such as HIV, AIDS, malaria etc. The results confirmed previous findings in Ugandans [
11] and concerning limited knowledge about DM in Africans [
12‐
15]. The limited knowledge about DM is also reflected in self-care measures undertaken to restore and maintain health, as many had problems in identifying the causes of their health problems and frequently used supernatural measures (prayers, holy water) and natural factors (herbal remedies). Frequent use of folk medicine and visits to traditional healers have previously been shown in Nigerians [
27], and the use of complementary alternative medicine might be explained by its accessibility in countries where this is part of and recognized in the existing health care system, as e.g. in Zimbabwe [
5]. However, knowledge deficit might be related to the organization of diabetes care, as many expressed dissatisfaction in contact with health care related to delays by doctors and disruptions in the continuity of care, and limited time for consultations affecting the encounters with physicians and the ability to pose questions and receive information about the management of DM. Another factor influencing knowledge might be the fact that staff managing the clinic were not specialized in the area of diabetes care, which has previously been shown to affect beliefs about health and illness in persons with DM [
28]. In a study in South Africa, lack of knowledge and need for further education related to diabetes care have been identified as barriers to optimal diabetes care [
29]. The health care system in the present study did not serve the diabetic persons and introduced barriers to health. Structural conditions in the health care system and the society thus, influenced individual beliefs about health and illness and the results confirm the importance of considering that population health is not only related to life-style but is also tied into concrete conditions of existence and a broader socio-economic context [
30]. Health promotion is an activity concerned with improving living conditions and empowering communities to gain control over the determinants of health. Reports from Havana [
31] demonstrate that a different approach to care in terms of empowering patients with skills and perceptions to cope with diabetes in a Continuing Interactive Education in group discussions, cultural activities, dining out, and the like can be effective in an impoverished situation. The patients might need a complete new setting to learn to live with the disease under their conditions.
Conclusions
Although limited knowledge was demonstrated there were indications of a potential to develop an attitude for improving knowledge and self-care if this is supported by relevant information about DM and improved socioeconomic conditions, as many respondents emphasized a willingness to comply with advice received, knew that the disease is life-long and had adequate fears of developing complications related to DM. Thus, it is important is to organize health care in a way that elicits individual beliefs about health and illness in persons with DM and then supports and provides the individual with appropriate information to strengthen the patient's self-care capability to become an active participant and partner in diabetes care [
13]. In a country and life situation with a highly strained economic situation, as for example in Zimbabwe today [
20] and in many other developing countries, health care needs to switch from predominantly focusing on disease control and compliance with medication to a holistic attitude starting from an individual perspective but also considering social determinants of health [
26,
30] to promote health and prevent DM and complications related to DM [
26] in order to decrease the burden of the disease in light of the overarching pandemic of DM [
2,
8]. Health promotive work need to focus on the importance of structural changes with improving living conditions and development of quality care easily accessible and equally delivered [
30]. The importance of patient education needs to be considered and the health care organization developed by giving room for the patient's thoughts and questions [
9‐
11,
18], considering the need for specialist training of staff working in diabetes care [
27], choosing an appropriate category of staff to provide patient education, and finding optimal strategies for teaching, as regards both methods and point in time and also to empower them and gain control over the determinants of health [
26,
30].
In conclusion, this study found limited knowledge about DM based on beliefs about health and illness, including both modern biomedical and traditional explanations related to the influence of supernatural forces such as fate, God, spirits, witchcraft etc., that influence health-related behaviour and thus self-care measures and care-seeking behaviour. A factor of the utmost importance affecting management of DM was the strained economic situation, and in order to develop cost-effective and optimal diabetes care in a country with limited economic resources and 'the double burden of disease' [
2,
7,
8] not only educational efforts based on individual beliefs are needed. Also the influence of structural factors in the health care system and society [
26,
30] need to be considered as regards both patients with DM and health care staff working in diabetes care, in order to promote health and prevent the occurrence of costly complications related to DM.
