Type 2 diabetes mellitus (DM2) is currently a global epidemic. Incidence and prevalence are increasing in developing and newly industrialized countries. Its impact on public health worldwide consists of social problems, such as reduced quality of life and reduced survival of people with DM2, and economic problems, such as reduced productivity and high treatment costs.
Among the several types of diabetes, DM2 accounts for 90%-95% of cases. It is characterized by an imbalance of the metabolism of carbohydrates, lipids, and proteins and is associated with a deficiency in the secretion and/or action of the hormone insulin secreted by the pancreas. As a consequence, there is a decrease in tissue sensitivity or insulin responsiveness and an increase in blood glucose levels. As a way to combat the complications of hyperglycemia, the goal of treatment is to achieve normal blood glucose levels.
An individual with DM2, if not properly treated and controlled, may develop acute complications, such as hypoglycemia, hyperglycemia, and chronic progressive changes in the retina, kidneys, and peripheral nerves, and may trigger atherosclerotic lesions of the heart, brain, and peripheral members.
Due to the requirement of constant glycemic control, chronicity, and lack of cure, the person with DM2 remains linked to the health system for decades and needs continuous attention focused on the integral care provided by family health and family support nucleus in actions to promote, monitor, and prevent complications of DM2. The complexity of care for people with DM2 requires an interdisciplinary approach with health professionals open to dialogue and willing to plan appropriate consultations and interventions to the specific needs of people with DM2 that are centered on the actions of self-care and glycemic control.
The purpose of the guidelines of self-care and self-control of DM2 proposed by the Brazilian Ministry of Health is to strengthen and qualify care to users and to health professionals through the integrality and longitudinality of care with this disease. Thus, users with DM2 and health professionals who work in primary care should have competencies for self-care and self-control in this pathology. According to Cyrino, competence is a person's ability to mobilize different knowledge to master specific problematic situations faced in daily life and to develop attitudes and practices.
To achieve the goals detailed by the Strategy for the Care of People with Diabetes Mellitus published in the Basic Care Book number 36 of the Ministry of Health, it is proposed that primary care professionals adopt the approach of person-centered health with DM2[6,7]. This approach allows primary care professionals to use objective methods such as anamnesis, physical examination, and laboratory tests as well as subjective methods for analyzing and understanding feelings and ideas, the effects of DM2 on one's life, and expectations of treatment. Thus, health professionals, in addition to the epidemiological and pathophysiological knowledge of DM2, must understand the psychosocial aspects of people; have pedagogical skills, communication skills, listening, understanding, and negotiating with the interdisciplinary health team. On the other hand, people with DM2 must have the skills and autonomy to assume self-care and self-control.
In this way, this article aims to present the self-care and self-control of people with DM2 under the objective point of view, taking into account the current recommendations based on scientific evidence, and also from the subjective point of view, emphasizing the aspects related to experience and the subjectivity of these people. Next, we present the essential skills for self-care and self-control of users and professionals working in primary health care.
SELF-CARE AND SELF-CONTROL OF PEOPLE WITH DM2 UNDER THE OBJECTIVE POINT OF VIEW
Self-care and self-control are shown as possibilities for the person with DM2 to reduce the repercussions caused by the disease. Self-care is understood as the set of activities that involve dietary, corporal, drug, and glucose monitoring practices performed by the patient to promote his health, minimizing hypoglycemia and excessive weight gain. Self-control is the monitoring of the conditions of health and disease by the subject himself, according to objective parameters obtained by biochemical tests of blood glucose and glycohemoglobin.
The main goal of self-management and self-control of people with DM2 is metabolic control and includes tests for fasting blood glucose and glycated hemoglobin. Glycated hemoglobin is the gold standard that provides an index of glycemic control for 6 to 12 wk, dosed quarterly until reaching control and then every 6 mo . In order not to increase the risk of hypoglycemia or other complications of treatment, the patient aims to reach values lower than or equal to 6.5 a 7.0[1,10] .
The monitoring of the annual lipid profile (triglycerides, total cholesterol and its fractions) is of fundamental importance for the control of DM2, since this indicator is associated with cardiovascular diseases, obesity, and arterial hypertension, which may favor the development of insulin resistance and metabolic syndrome.
Blood pressure should be measured query, with ideal targets for systolic pressure < 130 mmHg and diastolic blood pressure of < 80 mmHg. In addition, ophthalmologic evaluations, urinary albumin excretion, and comprehensive examination of feet should be made after the diagnosis in order to avoid retinopathies, nephropathies, ulcers, and amputations, respectively.
For self-care and self-management of DM2 in order to maintain glycemic control, to avoid acute complications, and to reduce the risk of long-term complications, it is recommended that people with D2M regularly participate in medical appointments and care health monitoring of biochemical and blood pressure tests, weight and abdominal circumference measurements, as well as evaluation of drug treatment, diet, and physical activity. But not enough people attend consultations regularly, making necessary adherence to self-care and self-control, which begins with the incorporation of dietary practices and physical activity prescribed by professionals in primary health care.
Behavioral modification related to dietary practices is a requirement imposed by the disease, and the selection of foods and fractionation of meals, energy consumption for the purpose of reducing or avoiding weight gain, and decreased consumption of trans and saturated fats, cholesterol, and sodium should be reviewed. These modifications improve insulin resistance and decrease plasma glucose, abdominal circumference, and visceral fat levels by improving the metabolic profile with reduced levels of low-density lipoprotein, triglycerides and increased high-density lipoprotein[12,13].
As for the body practices, 150 min per week of aerobic physical activity of moderate intensity is recommended. These activities include walking, cycling, running, swimming, and dancing, preferably three times a week, provided that there is no medical contraindication. Exercise improves glycemic control, reduces glycated hemoglobin and cardiovascular risk, contributes to weight reduction, and improves self-esteem. When associated with changes in eating habits, important components of maintenance of glycemic control and weight loss programs are important.
When the desired glycemic levels have not been reached after the use of dietary measures and exercise, antidiabetic medicinal products should be used. Some people with DM2 will require insulin therapy soon after the diagnosis and many throughout the treatment.
SELF-CARE AND SELF-CONTROL OF PEOPLE WITH DM2 FROM THE POINT OF VIEW OF THEIR EXPERIENCE AND SUBJECTIVITY
The subjects should be prepared and motivated from diagnosis to take the treatment. Although people are adaptable to the realization of self-care and self-control, compliance with these practices is not so easy for most people with DM2. At the moment the disease is discovered, the structure of daily life and the forms that sustain it are interrupted. First, ruptures occur with the new limits of normal daily life, as behaviors performed before being sick must be changed, potentially leading to deep breaks in one’s biography and self-concept. Finally, in the various segments of daily life, due to the care they need, people with DM2 must mobilize resources to face the changed situation.
At this stage, the person may be faced with the obstacle of food (one of the most difficult to overcome), the non-acceptance of DM2, fear of insulin, a lack of knowledge about the disease and self-care, the need for commitment and discipline, unfavorable financial situation, and the emotional component involved with feeding[4,15].
Thus, living with the limits imposed by a diagnosis of DM2 is full of conflicts, ruptures, questioning, and nonconformity. Knowing the experience and the subjectivity of these people, of the meanings attributed to them by the disease, favor the identification of limiting aspects and the way in which they articulate different aspects that interact in the production of self-care and consequently in self-control.
Some studies seek to approach the subject and his experience with the disease, taking into account the vision and participation in the management of care treatment adherence, the involvement of friends and family in the treatment, as well as support or self-help groups and social networks.
The experiences of individuals with the disease are socially shared, and their analysis is possible when expressed as subjective narration, that is, the conscious or unconscious mind of people. Thus, one approach to the subjective questions is the social representations, understood as complex subjective productions, because they have an impersonal aspect, in the sense of belonging to all; they are the representation of others, belonging to other people or to another group and are also a personal representation, perceived effectively as belonging to the ego.
Social representations play a fundamental role in the dynamics of social relations by understanding and explaining reality, guiding behaviors and practices, explaining and justifying behaviors in a situation or with partners, and defining identity. The author emphasizes a clear relationship between social representation, identity, and the behavior of people.
It is necessary, then, to understand the social representations in which people with DM2 are anchored and the social identities that underlie them. With this intention, Amorim et al[22,23] investigated the identity representations of users with DM2 of a basic health unit, located in Belo Horizonte, Brazil. From the guiding question: "what comes to mind when I speak, I am diabetic", the speeches were categorized and interpreted by the technique of content analysis and theories of social representation and social identity. As a result of this research, some people with DM2 studied are considered normal, others accept the disease, there are those who are dissatisfied, and others lead a life with difficulty. The "normal" participants coexist with illness in a positive way and minimize the impact of DM2 on their identity when they experience the process of normalization of illness and care, in which the changes and adaptations required to the treatment become routine and are incorporated into daily life. Participants who "accept the disease" do not ideally accept their chronic illness. The ideal acceptance of a disease consists of a psychological state in which the illness is part of the perception of reality and is not perceived as a factor that limits the person. The unfavorable attitudes of the "non-conforming" participants, the information about the risks of the disease and the image of danger that they elaborate on the illness, help to understand the sense that the participants attribute to the "diabetic being". Participants who think that they "have a life fraught with difficulties" face obstacles in taking care of themselves, culminating in negative feelings and attitudes about the disease. It is possible that people with "distressed" DM2, not feeling confident about the future and facing adversity, do not make sustained efforts to achieve their goals, neglecting self-control and self-care. Thus, the obstacles faced by participants who think they are "accepting the disease, think they are "discontented" and “have difficulties" when they put into practice self-care, especially in relation to food, should be understood by the team that works in primary health care, biomedical logic[22,23].
The social representations about the feeding of these people with DM2 were investigated. Some respondents indicated that the person with DM2 should eat healthy. Others relied on the quality of food, representing it as "eating vegetables and fruits" and "avoiding sweets." There are still those whose speech was based on eating little, worrying about the quantities of food eaten. There are those who represented eating as not eating too much, focusing on the frequency of feeding, as they consider that breaking down the food in many meals is not appropriate. Others focused their speech on selective food intake, specifically those that do not harm the body. Finally, others considered that food does not imply following a specific diet[24,25].
In analyzing the social representations of the diet of people with DM2 as they represent their identity and its implications for glycemic control, it was found that adequate HbA1c values of the participants considered to be "normal" are adequate and are related to the actions of self-care, allowing to infer about the effectiveness of feeding. Proper nutrition improves insulin resistance, decreases the levels of plasma glucose and waist circumference, and improves metabolic visceral fat profile of triglycerides and cholesterol. People who think they have a normal life represent eating in the categories eating healthy, eating reduced, eating vegetables and fruits, and divert from sweets.
The particular way in which the participants who judge "accepting the disease", "having difficulties", and "nonconformists" perform the self-care related to the alimentary practice is derived from the different processes of subjectivation in which each one of them relies on to construct its social representations on the identity and feeding and consequently have mean values of HbA1c above normal values. Participants who "accept the disease" are based on "no" to represent their diet: do not eat too much and do not eat at all. Participants who "have a life with difficulties" represent their eating in the negative categories: do not eat too much, do not eat at all, and do not follow the diet. A participant who represents eating in eating vegetables and fruits, unlike normal people, has difficulty putting their thinking into practice. "Nonconformists" represent their food in the negative categories: not eating much and not eating at all. Two participants represented their diet in eating vegetables, but in practice they eat the forbidden foods.
USER ABILITIES REQUIRED FOR SELF-CARE AND SELF-CONTROL
The adherence of people with DM2 to self-care and self-control therapies is still low in developed countries, with around 50%, and it is estimated that in developing countries this percentage is lower, compromising the effectiveness of the treatment.
Due to the complexity of self-care and self-control in DM2, Cyrino, based on the literature and the joint evaluation with specialists in the area, defined a list of competencies required by people with DM2 to conduct the treatment. A total of 47 skills classified in the fields of knowledge - technical dimension of illness and know-how-practical dimension were elaborated, contemplating the general notions about DM2 and its complications, glycemic self-control, self-care in acute complications, and self-care in drug treatment.
In addition to the knowledge and skills portrayed in the competency roll, it is necessary to consider the attitudes and the necessary awareness that influence the user's behavior and consequently the health improvement. For Sousa et al the increase in knowledge when correlated significantly with attitude is associated with the predisposition to assume self-care.
In order to verify the knowledge and attitudes of people with DM2 who partici-pated in a self-care education program, Rodrigues et al used the instruments validated for use in Brazil, the Diabetes Knowledge Questionnaire and the Diabetes Attitude Questionnaire. The Diabetes Knowledge Questionnaire covers issues related to knowledge about basic physiology, hypoglycemia, food groups and their substitutions, management of DM2 in the course of another disease, and general principles of care. The Diabetes Attitude Questionnaire presents issues that include stress associated with DM2, treatment receptivity, treatment confidence, personal efficacy, health perception, and social acceptance. After applying these two instruments, Rodrigues et al concluded that although participants had a good level of knowledge, they still did not change their attitude towards coping with the disease.
As knowledge does not always lead to a change in attitude towards the daily demands that treatment imposes on daily life, it is necessary to listen to the feelings, the hidden complaints of the person with DM2. In this line of reasoning, according to which the subjective perspective of the patient is considered and valued, Cyrino developed a study with the objective of knowing the skills developed by users with DM2 of a health service for self-care and self-control in DM2, from their testimonials. A set consisting of 98 competences derived from the knowledge of the experience of those who live the disease was raised, distributed in the fields of knowledge, know-how and know how to be and know how to communicate. The competences related to psychological and social difficulties to self-care were expressed by people with DM2, showing differences in conceptions about the disease and care among health professionals and their patients.
To know the skills of people with DM2 for self-care, a scale containing 27 items was developed and validated, assessing physical abilities (vision, touch, dexterity, and manual ability), mental abilities (reading, attention, memory, discrimination and classification of knowledge within certain situations, judgment of certain situations, and conceptualization of a system of actions to act in certain situations), and motivational and emotional capacities[31,32]. This scale of identification of the competence of the person with DM2 for self-care (ECDAC) allows a qualitative and quantitative evaluation of the capacities of people with DM2 for the exercise of the self-care actions necessary for the maintenance of health. The deficiencies in the physical, mental, and motivational capacities pointed out by the ladder provide subsidies for the planning and implementation of intervention methods based on the person-centered approach, favoring a global and individualized assistance practice.
ABILITIES OF HEALTH PROFESSIONALS NECESSARY FOR SELF-CARE AND SELF-CONTROL
The complexity involved in self-care and self-management of people with DM2 requires an approach of interdisciplinary care with family health strategy professionals and family health support nucleus open to dialogue, with the ability to communicate, employing person-centered care and valuing the objective and subjective aspects. In this sense, it is recommended that these professionals overcome the biomedical paradigm of being the experts responsible for curing diseases and help people achieve health and normality, through a systemic and comprehensive view of the individual, family, and community in the promotion, specific protection, rehabilitation, and care, working with creativity and critical thinking.
Within this context, Torres et al developed a training program for primary health care professionals for DM2 education. The competency role required by people with DM2 to conduct the treatment developed by Cyrino was adapted and applied, including questions related to pathophysiology, nutrition, physical exercise, and insulin therapy, to assess the knowledge of the professionals of basic health units concerning self-care. The difficulties identified by the professionals pointed out the need for continuing education and supported the planning and development of the educational program in DM2. For the professionals' training, the work workshops modality was used to motivate the exchange of experiences and knowledge and reflection on the obstacles they experienced in their daily lives when caring for people with DM2.
In order to overcome these obstacles, primary health care professionals should value the individual's own experience, his subjectivity, his conceptions of illness[17,37], as well as his beliefs[38,39]. By living the disease in their everyday experience, the subject mobilizes knowledge and attributes meanings to master specific problematic situations, developing the skills (i.e. attitudes and practices related to self-care and self-control in DM2).
Thus, in practicing the person-centered approach, health professionals should have the ability to distinguish the disease from the experience of the disease, so that they find methods of health promotion and preventive care more appropriate to the world of the person, varying according to the person, the moment, and the question of health care. The use of qualitative methodologies provides an in-depth understanding of the broad context of understanding the subjective issues of the person being treated.
After this stage, health professionals and the person in care should work together on a joint problem management plan to define goals, care priorities, and care roles. To apply problem solving requires the ability to recognize the problem, ability to generate alternative solutions, and insight to select an appropriate option.
This pathology requires a holistic view of the health-disease process by the health professional, with the apprehension of the subject in its biopsychosocial dimension, integrating preventive, promotional, and coordinated assistance actions, for a more comprehensive understanding of the disease and to favor more effective interventions and accession. A structured intervention in multidisciplinary teams for the effective development of programs of education and health promotion of these patients and relatives is fundamental.
The abilities for self-care and self-control in DM2 of users and health professionals are illustrated in Table 1.
Table 1 Abilities for self-care and self-control in diabetes mellitus type 2.
Abilities for self-care and self-control in diabetes mellitus type 2
People with diabetes face obstacles, often filled with social representations. The rules to be followed by these individuals should be adapted to deal with the restrictions, prohibitions, and difficulties that act as contingency to put into practices the desired behavior.
So, to ensure the effectiveness in meeting the people with DM2, the experience of listening, the ability to communicate and understand the subjective aspects of people and the context in which they operate, is a key skill to be developed by health professionals in primary health care. A change in the behavior of health professionals is possible to be motivated by the institution in which it is linked as well as by an internal involvement mediated by the self-conscience of its professional activity.
On the other hand, people with DM2 should have knowledge about the disease, motivation and positive attitude from diagnosis to self-control and self-care, and support from the social network and family. Participation in the educational process should be active, this essential condition to ensure effective results for better acceptance of the disease, treatment adherence, metabolic control, and quality of life.
