Well-being in high-risk pregnancy: an integrative review.

BACKGROUND: A prerequisite to the interventions for well-being improvement in high-risk pregnancy (HRP) is to make the concept clear, objective, and measurable. Despite the wealth of studies into the concept of well-being in HRP, there is no clear definition for it. This study aimed to explore the concept of well-being in HRP.
METHODS: This integrative review was conducted using the Whittemore and Knafl's approach. A literature search was done without any data limitation in dictionaries, thesauruses, encyclopedias, well-being-related textbooks, midwifery, psychology, and mental health journals, and Iranian and international databases. The most primary inclusion criterion was relevance to well-being in HRP. The full-texts of all these articles were assessed using the checklists of the Joanna Briggs Institute. Data were analyzed through the constant comparison method and were managed using the MAXQDA 10 software. Meaning units were identified and coded. The codes were grouped into subcategories and categories according to the attributes, antecedents, and consequences of well-being in HRP.
RESULTS: Thirty articles were included in the review, from which 540 codes were extracted. The codes were grouped into seven main attributes, eight main antecedents, and five main consequences of well-being in HRP. The four unique dimensions of well-being in HRP are physical, mental-emotional, social, and spiritual well-being. These dimensions differentiate well-being in HRP from well-being in low-risk pregnancy and in non-pregnancy conditions.
CONCLUSION: As a complex and multidimensional concept, well-being in HRP refers to the pregnant woman's evaluation of her life during HRP. It includes physical, hedonic, and eudaimonic components. The assessment of well-being in HRP should include all these components.

Background

Pregnancy is a critical period in women’s lives because pregnant women experience different physical, mental, and social changes. Ineffective coping with such changes cause them serious problems [1]. Although pregnancy is a physiologic phenomenon, some conditions may endanger maternal or fetal health and thereby, turn pregnancy into a high-risk pregnancy (HRP) and cause women to experience stressful conditions [2]. Almost 22% of pregnant women face with HRP [1].

HRP is associated with different physical complications which in turn can cause mood changes and mental and social problems. Studies showed that women with HRP experience negative feelings such as restlessness, fear, loss of control, disability, anger, and anxiety [3-5]. A qualitative study also showed that besides medical problems, women with HRP experience behavioral, affective, and emotional problems as well as problems in personal and familial role performance. Moreover, they are at risk for sociocultural and financial strains and uncontrollable feelings such as uncertainty, concern, and insecurity [4]. Consequently, HRP threatens women’s well-being [4, 6].

Well-being is a widely-used concept in different disciplines [7], particularly in health-related disciplines. Yet, there is no clear definition for it and controversies exist over its definition [8]. Oxford dictionary defines well-being as “the state of being comfortable, healthy, or happy” with the three dimensions of physical, emotional, and psychological well-being [9]. Similarly, Cambridge dictionary defines it as “the state of feeling healthy and happy” [10]. Mosby’s medical dictionary defines it as the “achievement of a good and satisfactory existence as defined by the individual”. In nursing, well-being is considered as personal satisfaction with health status as expressed by individuals [11]. The World Health Organization considers well-being as a keyword in the definition of health, with physical, spiritual, and social dimensions. It also uses well-being to define mental health as the following: “a state of well-being in which every individual realizes his or her own potential, can cope with the normal stress of life, can work productively and fruitfully, and is able to make a contribution to his or her community” [12]. Controversies also exist over the definition of well-being in HRP. Some studies vaguely addressed well-being in HRP [13] and some considered well-being in HRP as the lack of depression, anxiety, or other psychological disorders [14-17]. Another study also equated well-being with physical health [18].

Provision of a clear and objective definition for well-being is a prerequisite to its assessment and improvement among women with HRP [19]. Because of the lack of such definition, the present integrative review was conducted to explore the concept of well-being in HRP.

Methods

This integrative review was conducted using the Whittemore and Knafl’s approach. Integrative review allows the assessment of both empirical and non-empirical studies. In this method, concepts are defined, theories and evidence are reviewed, and methodological issues related to the intended concept are analyzed to extract its attributes, antecedents, and consequences, further clarify the concept, and provide a better understanding and clearer definition for it [20, 21]. The Whittemore and Knafl’s integrative review approach consists of five stages, namely problem (or concept) identification, literature search, data evaluation, data analysis, and presentation.

Stage 1. Problem identification

The first stage of each review is to clearly identify the intended problem or concept, acquire an in-depth understanding of it, determine the appropriate sampling framework, and clarify the relevant questions [21]. The main questions of the present study were: “How can the concept of well-being in HRP be clearly defined?” “How is the concept of well-being in HRP defined in different disciplines and communities?” and “What are the uses of the concept of well-being in HRP in the literature?”

Stage 2. Literature search

An online search was conducted in the following Iranian and international databases, SID, Irandoc, Magiran, Google Scholar, CINAHL, Medline via OVID, Embase, PsychINFO, NLM Gateway, Web of Science, Cochrane, ProQuest, ScienceDirect, and Scopus. Search keywords were “high-risk”, “complicated”, “pregnancy”, “maternal”, “mother”, “women”, “wellbeing”, and “well-being”. These keywords were combined using Boolean operators “AND” and “OR”. The search protocol was not limited to any time period. The reference lists of all retrieved articles were also assessed for any relevant study. Dictionaries, thesauruses, and encyclopedias were also searched to determine the definitions, synonyms, and expressions used to describe well-being in HRP. Manual search was also conducted in midwifery, psychology, and mental health journals as well as well-being-related textbooks. The literature search was done and reported using the four-step Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guideline (Fig. 1). The four steps of this guideline are record identification, record screening, eligibility assessment, and inclusion [22].

The PRISMA flow diagram

Records were included if they were related to well-being among women with HRP and had been published in English or Persian. Records addressed well-being in relation to healthy pregnancy, delivery, postpartum period, fetal death, and perineal injuries were not included. In order to reduce record selection bias, literature search and eligibility assessment were performed by two independent researchers (i.e. the first and the corresponding authors). They assessed the titles and the abstracts of the retrieved articles and excluded the ineligible articles.

The primary literature search yielded 15,385 records, 4563 of which were excluded due to duplication. The EndNote reference management software was used to determine and exclude the duplicated records. During the screening step, the titles and the abstracts of the remaining articles were assessed and 10,730 articles were excluded because they were not relevant to the study aim and questions. Moreover, 62 articles were excluded due to ineligibility. Finally, thirty articles were included in the study (Fig. 1) (Table 1). During literature search, we found no textbook relevant to the study aim and questions.

Stage 3. Data evaluation

The 30 articles included in the integrative review were three clinical trials [48, 49, 52], eight descriptive studies [28, 30, 33, 37–40, 50], five reviews [26, 31, 34, 42, 45], two systematic reviews [24, 25], eight cohort studies [14, 27, 35, 36, 41, 46, 47, 51], three qualitative studies [23, 32, 43], and a cross-sectional study [44] (Table 1). The full-texts of all these articles were assessed using the checklists of the Joanna Briggs Institute (JBI). The JBI developed different design-specific checklists for the assessment of studies with different designs [53]. The first and the corresponding authors of the present study independently assessed the included studies using design-specific JBI checklists and resolved their disagreements through seeking other authors’ comments. Articles obtained at least 65% of the total score of the JBI checklists were included in the final analysis [54, 55]. The following questions were also used for eligibility assessment: “Does the article describe well-being in HRP?” “Does the article provide an explicit or implicit explanation or instances of well-being in HRP?” “Has the article introduced or assessed the attributes, antecedents, or consequences of the concept of well-being in HRP?”

Stage 4. Data analysis

Data analysis was performed using the four-step constant comparison method. The four steps of this method are data reduction, data display, data comparison, and conclusion drawing and verification. Data reduction refers to the coding of the data in a manageable framework. Excerpts of the included articles which were relevant to the concept of well-being in HRP were considered as meaning units and were coded. In the second step, the codes were displayed in two tables (Tables 2 and 3). In the third step, the codes were frequently compared with each other, similar codes were grouped into subcategories, and similar subcategories were grouped into categories. In the fourth step, the results were arranged into the following main categories: definitions, attributes, antecedents, and consequences [21, 56]. The MAXQDA 10 software was employed for managing the data.

Results

During the integrative review of the 30 articles, 540 codes about well-being in HRP were extracted (Table 2). Findings revealed that there were different definitions for well-being in HRP, none of which was comprehensive. Thus, the attributes, antecedents, and consequences of the concept were extracted (Table 3) in order to provide a better understanding about it.

The attributes of well-being in HRP

Through the analysis of the explicit and the implicit definitions of well-being in HRP, seven attributes, symptoms, or components were identified for the concept. These attributes were as the following: well-being as a multidimensional and complex concept [29, 52], controlled physical conditions [26, 32], controlled mood, emotions, and affections [14, 29], perceived threat [32, 48], self-efficacy and competence for multiple role performance [29, 44], maintained social relationships [23, 32], and meaning seeking and relationship with the Creator [39].

Well-being as a multidimensional and complex concept

Well-being in HRP is a multidimensional and complex subjective concept which may change during pregnancy. It is integrated with the concept of health and is considered as the abstract understanding of health [29, 52].

Controlled physical conditions

Well-being in high risk pregnancy refers to the successful control of physiologic parameters [26, 57] and successful control of physical health conditions [32, 51]. In other words, it denotes that the physical problems of HRP have been controlled and are bearable [47, 51].

Controlled mood, emotions, and affections

The components of negative well-being in HRP are anxiety [14, 27, 28, 41, 48], depression [14, 24, 44, 47], and stress [14, 24, 32, 40, 44, 57]. A woman with HRP may feel well-being when she is satisfied with her conditions, her positive feelings overweigh her negative feelings [32, 37, 47], and does not experience unpleasant affective and emotional feelings [23, 44, 46]. Thereby, well-being in HRP is achieved when mood, emotions, and affections are under control.

Perceived threat

In HRP, women with poor well-being feel concern and have fear over the adverse consequences of pregnancy [37, 44, 45]. They may feel that they and their fetuses are at risk for threats and hence, are uncertain about pregnancy outcomes [37, 40, 41, 43, 44].

Self-efficacy and competence for multiple role performance

One of the key components of well-being in HRP is self-efficacy and self-control for showing appropriate responses to pregnancy [44, 52]. Limitation of behaviors and activities [14, 38], a sense of strain, and damages to maternal roles in family [23, 32] are indicative of poor well-being in HRP.

Maintained social relationships

Damage to social activities and relationships and disturbances in marital relationships also indicate poor well-being in HRP [32].

Meaning seeking and relationship with the Creator

Well-being in HRP is an abstract concept with two existential and religious dimensions. It is closely related to pregnant women’s mental and general health [34, 39, 42].

The antecedents of well-being in HRP

Data analysis revealed that the antecedents of well-being in HRP were personal and socioeconomic characteristics, physical tensions, availability and perceived quality of health services, psychological context, social support, interpersonal relationships, coping strategies, and spirituality and religiosity. These are explained in the following.

Personal and socioeconomic characteristics

Personal and socioeconomic characteristics such as age, number of pregnancies, educational level, marital status, income level, and employment status are related to well-being in HRP [33, 41, 44, 47, 48]. Accordingly, women who are nulliparous, younger [33], with a lower educational level [44], lower financial status, and financial insecurity are at greater risk for poorer well-being [23, 41, 47, 48].

Physical tensions

Physical problems such as pain, nausea, and vomiting are the predictors of poor well-being in HRP. The tension caused by the physical problems of pregnancy, development of pregnancy to an HRP, and hospitalization-induced functional limitations can be associated with psychological distress and poorer well-being in HRP [14, 23, 24, 31–33, 35, 37, 39, 40, 44, 47, 49, 57].

Availability and perceived quality of health services

Good access to healthcare services gives women with HRP the sense of well-being [32, 37, 49]. Contrarily, limited access to diagnostic, therapeutic, and intensive care services are associated with fear, stress, and poorer well-being [32, 49]. Moreover, mothers who perceive that health services are appropriate and are not disturbing feel higher levels of well-being [32, 38]. Informed and free choice of health services also improves satisfaction and well-being among pregnant women [43, 49].

Psychological context

The history of psychological disorders, critical negative life events [23, 35, 37, 47], adverse pregnancy outcomes in previous pregnancies [37, 44, 49], and infertility is associated with lower levels of well-being in HRP [30, 49]. Conversely, wanted pregnancy and personal competencies such as good self-esteem improve well-being in HRP [29, 33, 41, 47, 48].

Social support

Social and emotional support received from family, spouse, peers, neighbors, colleagues, and healthcare providers can improve well-being in pregnancy [23, 32, 37, 40, 41, 44, 47, 48]. Moreover, supportive rules, regulations, and services at workplace and in communities for women with HRP are associated with higher levels of well-being [41]. Informational support and quality educational services by healthcare providers and the possibility of communication with successful peer models can also improve well-being among women with HRP [37, 38, 43, 49].

Interpersonal relationships

Healthy and committed marital relationships improve well-being among pregnant women, while poor marital relationships reduce it [23, 48]. Moreover, healthcare providers’ empathy with pregnant women improves their well-being [37, 49].

Coping strategies

Coping strategies can also affect well-being through reducing stress and depression, increasing engagement in recreational activities [23, 32, 37, 44], and promoting adherence to health-promoting behaviors [35, 38, 48].

Spirituality and religiosity

Spiritual and religious beliefs and engagement in religious rituals can also improve well-being among women with HRP [39].

The consequences of well-being in HRP

The integrative review of the existing literature revealed five main consequences for well-being in HRP. These consequences were maternal health [31, 37], mother-fetus emotional attachment [24, 33], success in pregnancy [14, 45, 49], fetal well-being [24, 25, 36, 45], and consequences related to child’s future [25, 36, 50].

Maternal health

Pregnant women with lower well-being are less likely to engage in health-promoting behaviors [33]. Well-being is a facilitator to the achievement of physical health and is associated with lower morbidity and mortality rates [14, 29]. Well-being also improves mental health among pregnant women [39].

Mother-fetus emotional attachment

Poor maternal well-being ruins maternal image of the fetus as a real person [24] and thereby, negatively affects mother-fetus emotional attachment [33].

Success in pregnancy

Well-being in pregnancy is associated with a successful pregnancy [14, 45]. Contrarily, poor well-being in pregnancy is associated with adverse pregnancy outcomes [45, 49]. For example, it can increase the likelihood of preterm delivery .

Fetal well-being

Fetal well-being directly depends on maternal well-being, so that changes in maternal well-being are associated with changes in fetal well-being [58, 59]. For example, maternal depression or emotional distress during pregnancy can result in retarded fetal growth [45], fetal hyperactivity, and irregular fetal heart rhythm. Hormonal, nervous, and epigenetic changes in the fetus are also observed in case of poor maternal mental-emotional well-being [25]. Moreover, poor maternal physical well-being can be associated with low birth weight and preterm delivery. Contrarily, improvement in maternal wellbeing reduces adverse fetal outcomes [37].

Consequences related to child’s future

Poor maternal well-being can result in adverse neonatal and infantile consequences such as low birth weight, prematurity, increased neonatal mortality rate, hormonal and nervous changes, and motor and behavioral disorders. Moreover, the child of mothers with poor well-being in pregnancy may develop growth and development disorders, autism spectrum disorders, and behavioral and criminal disorders later in adolescence [24, 25, 36].

The definition of well-being in HRP

Well-being in HRP is a multidimensional, complex and abstract subjective concept and a cognitive and emotional self-evaluation of one’s own life in HRP. Its four main dimensions are physical, mental-emotional, social, and spiritual well-being. These dimensions are interrelated and affect each other. In the physical dimension, pregnant women with good well-being have control over their physiologic parameters and physical health conditions. In the mental-emotional dimension, women with good well-being have more positive feelings towards their pregnancy, so that they have lower concerns, fears, depression, anxiety, and stress in relation to the adverse maternal and fetal outcomes of pregnancy, are more satisfied with their conditions, and feel greater self-efficacy for managing their conditions in HRP. In the social dimension, women with good well-being in HRP are able to fulfill their roles and maintain their social interactions and have positive interpersonal relationships. In the spiritual dimension, they have meaning and purpose in life and pregnancy and establish relationships with God or a supreme power. Well-being in HRP is affected by personal and socioeconomic characteristics, physical, mental, social, environmental, and behavioral contexts, and spiritual and religious beliefs. HRP among women with good well-being is associated with lower adverse maternal, fetal and infantile consequences.

Discussion

This integrative review aimed to explore the concept of well-being in HRP and identify its attributes, antecedents, and consequences. Findings indicated that multidimensionality, complexity, and subjectivity were among the characteristics of well-being in HRP. These characteristics are also for the concepts of general well-being [60-62] as well as situation-specific well-being such as perinatal well-being and well-being in other disciplines [63, 64]. Yet, complexity, multidimensionality, and subjectivity are not unique to the concept of well-being; rather, many other concepts such as quality of life and comfort are multidimensional, complex, and subjective. Despite their similar characteristics, concepts such as quality of life and comfort cannot interchangeably be used with the concept of well-being [65, 66].

Findings also showed that the four dimensions of well-being in HRP concept were physical, mental-emotional, social, and spiritual well-being. Similarly, a former systematic review reported that child well-being includes the five physical, psychological, cognitive, social, and economic dimensions which vary from negative to positive well-being [67]. Well-being in pregnancy may also vary from positive to negative extremes [63]. Compared with low-risk pregnancy, negative well-being is perceived more commonly in HRP [68]. Although the dimensions of well-being in HRP are in some ways similar to the dimensions of well-being in other conditions, their definitions and subcategories are different. Well-being refers to self-perception and self-evaluation of one’s own position in life with respect to goals, expectations, standards, and concerns. Consequently, well-being in HRP differs from HRP in low-risk pregnancy and non-pregnancy conditions, though well-being is a complex and multidimensional concept in all conditions. Some studies suggested that pregnancy is associated with feelings of happiness, satisfaction, and self-worth because reproductive role is socially well-accepted. A concept analysis of the perinatal well-being concept defined well-being as the level of adaptation to pregnancy-induced physical and emotional changes which has physical, psychological, social, spiritual, economical, and ecological dimensions and is affected by cultural, social, spiritual, ecological, and economic factors [63]. In the present study, economic and ecological factors were determined as the antecedents of the well-being concept not as its attributes. Another study defined well-being in low-risk pregnancy as the absence of any illness [69]. However, the present study showed that well-being can also be defined in HRP, where pregnant women suffer from a disorder of illness.

In the presents study, the physical well-being dimension was one of the most common attributes of well-being in HRP. Physical well-being is necessary and important to achieve general well-being and health [66, 70]. This dimension refers to the successful control of physiologic parameters and physical health conditions [26, 32, 43, 51]. Physical disorders can turn normal pregnancy into HRP [2, 71]. Therefore, physical disorders, perceived and expressed as ailment, are the first problems experienced by women with HRP compared with normal pregnancy. In other words, a woman feels acceptable level of well-being when her physical problems are under control, her physiologic parameters are in safe ranges [72], and she is able to cope with physical stress [51]. Physical well-being also refers to functional ability and pertains to environmental factors such as facilities, equipment, and habitation standards [60, 73]. A previous study into the well-being of doctorate students also found physical well-being, health maintenance, and work-life balance as the components of well-being [64]. However, a study into the concepts of well-being and quality of life reported that the core of well-being is its psycho-spiritual dimensions, happiness, and inner energy and did not consider physical well-being as a key component of well-being [65]. Some scholars believe that the physical dimension of well-being is more evident in medicine and nursing [65, 71]. Physical tensions and suffering [14, 32, 47] and perceived quality of health services were among the antecedents of physical well-being in HRP in the present study. Thus, reducing pregnant women’s physical tensions and suffering and improving their access to quality health services can improve their sense of well-being [32, 38, 43, 49].

Mental-emotional well-being was another dimension of well-being in HRP. The characteristics of mental-emotional well-being are successful control over mood, emotions, and affections, perceived threat, sense of self-efficacy, and competence for multiple role performance. A pregnant woman may have low levels of well-being if she is experiencing depression, anxiety, and stress [14, 41, 47, 48, 74] and feels guilty and alone [19, 37, 46]. Contrarily, a woman with feelings of satisfaction [32, 37, 47–49], vitality [44], hopefulness [46], and successful control over mood and emotions will feel acceptable level of well-being in HRP.

Perceived threat is a component of psychological well-being. A pregnant woman with HRP may feel threat due to her fear and concern over the adverse outcomes of pregnancy and uncertainty about pregnancy outcomes. In other words, well-being in HRP largely depends on feelings of safety and security [40, 41, 43]. Safety is also a key component of well-being in other disciplines [64, 75, 76]. However, the difference between well-being in HRP and well-being in other disciplines pertains to pregnant woman’s confidence in her health, her fetus’s health, and pregnancy outcomes.

Perceived threat and successful control of mood, emotions, and affections in the psychological dimension of well-being in HRP refer to the hedonic approach to well-being. In this approach, well-being is defined based on pleasure, happiness, positive emotions [61, 62, 77], balance between positive and negative emotions, and happiness [78-80]. In other words, the components of psychological well-being are positive emotions and affections, life satisfaction, marital satisfaction, positive mood, and absence of depression and anxiety [81]. Accordingly, a person with great life satisfaction, deep feeling of pleasure, and low levels of negative emotions (such as discomfort, tension and anger) will have high levels of psychological well-being and vice versa [82, 83].

Findings revealed that the psychological context of a woman with HRP affects her well-being and thereby, it is an antecedent of her mental-emotional well-being. Studies reported that the history of psychological disorders, negative life events [23, 35, 37, 47], negative pregnancy outcomes [37, 44, 49], and infertility are associated with low levels of well-being among women with HRP [30]. On the other hand, effective coping strategies can reduce stress and improve well-being [23, 32, 37, 38, 84–88]. Therefore, interventions are needed to improve coping skills among women with HRP.

Self-efficacy for the management of HRP was another aspect of mental well-being in HRP in the present study. Most health and well-being theories assert that feeling control over thoughts, feelings, behaviors, environment [89, 90], body and high-risk conditions of pregnancy and personal ability to manage pregnancy and its complications are among the key components of well-being [29, 44].

We also found competence for multiple role performance as another aspect of psychological well-being in HRP. HRP may cause disturbances in personal and familial life, inefficiencies in role performance and thereby, give women feeling of incompetence in role performance [4]. Competence was also reported to be a component of well-being in other disciplines. For instance, a previous study assessed faculty well-being based on the Self-Determination Theory. The two main components of this theory are competence and autonomy [91]. Another study used a competence scale to assess well-being among the parents of preschool children with autism [92].

Maintaining marital, interpersonal, and social relationships was identified as the social dimension of well-being. In HRP, women experience problems in their personal, familial, and social life [4, 5] and hence, their well-being is damaged. Contrarily, maintaining normal social relationships and interactions can help women with HRP protect their well-being. We also found social support and interpersonal relationships as the antecedents of social well-being in HRP. Three earlier qualitative studies reported social support and empathetic relationships with spouse, healthcare providers, and society as the fundamental needs of women with HRP [5, 93, 94]. Social well-being is also among the key components of well-being in other disciplines [65, 67, 76]. For instance, active engagement in social activities, quality social relationships, and maintenance of positive relationships with spouse, peers, and relatives were reported as the components of general, geriatric, and perinatal well-being [60, 63, 72, 76]. A former concept analysis study also found dynamicity in interactions, maintenance of relationships, negotiation for growth and development, and social support as the attributes of the concept of well-being in older adults [95].

Meaning seeking and relationship with the Creator were extracted as the spiritual dimension of well-being in HRP. Spiritual well-being was conceptualized by Ellison in 1983 [96]. It has two dimensions, namely existential and religious well-being. Existence is the horizontal aspect of spiritual well-being and encompasses meaning and purpose in life, while religion is the vertical aspect of spiritual well-being and refers to relationship with God or a supreme power. Spiritual well-being has close relationship with physical and mental health [97]. Spiritual well-being helps women cope with HRP-associated stress [98]. It is affected by spirituality and engagement in religious rituals which were extracted in the present study as its antecedents.

Self-efficacy for managing HRP, competence for multiple role performance, maintained social relationships, positive interpersonal relationships, and meaning seeking and relationship with the Creator, which were identified as the components of well-being in the present study, are close to the underpinnings of the eudemonic approach to well-being. Ryff, a eudemonic theorist, holds that well-being should not simply be equated with greater pleasure; rather, it encompasses attempts for perfection and actualization of individual potentials. To define well-being, she combined theories in the following six areas: self-acceptance, positive relations with others, autonomy, environmental mastery, purpose in life, and personal growth. According to the eudaimonic approach, well-being is the ability to address three main psychological needs, namely autonomy, competence, and relationship [99-101]. A study, with the assumption that Japanese people have lower level of well-being compared with western people, reported that Japanese people’s well-being is closer to the eudaimonic approach than the hedonic approach [102]. Contrarily, people in the Latin American countries, who have lower socioeconomic status, have higher levels of hedonic well-being and hence, development in these countries necessitates interventions to improve eudaimonic well-being [76]. These findings denote that well-being assessment and improvement in HRP should be performed using a holistic approach to address not only positive feelings, pleasure, peace, and satisfaction, but also awareness of values and meaning in life [103].

The main outcomes of well-being are general health and quality of life [75, 76]. As pregnancy directly involves two persons, i.e. a pregnant woman and her fetus, the outcomes of well-being in pregnancy can affect the health of both woman and fetus. Maternal well-being can affect fetal health and well-being through affecting mother-fetus relationships and causing hormonal and behavioral changes in the fetus. Studies showed that depression and distress are among the components of poor well-being in HRP [14, 24, 32, 44, 57]. These components can affect the health and the future of the fetus. Maternal depression can also cause neuromotor impairments, growth and development disorders, speech disorders, and autism spectrum disorders during childhood and criminal behaviors during adolescence [25].

Strengths and limitations

The strengths of the present study were its integrative review design and inclusion of studies without any date limitation. The limitations of the study were the inclusion of only English or Persian articles, inaccessibility of gray literature, and analyzing the data and interpreting the findings using a subjective approach.

Conclusion

Well-being in HRP refers to the pregnant woman’s evaluation of her life during pregnancy. As a complex and multidimensional concept, well-being in HRP includes a physical component, hedonic components such as balance between positive and negative feelings, and three eudaimonic components, namely autonomy, competence, and relationship. Thus, well-being assessment and improvement programs need to address all these components. Due to the significant effects of well-being on both maternal and fetal health, policies and interventions are needed to improve the different aspects of well-bring in HRP. As previous studies used different instruments for well-being measurement, an integrative review is recommended to review all these instruments. Moreover, a comprehensive instrument should be developed for well-being measurement in HRP. That instrument should be tested in different cultures and settings.

This integrative review provides a clear understanding about well-being in HRP and hence, its results can be used in both theory and practice. Healthcare providers usually focus mainly on the physical aspect of health during HRP management and may neglect pregnant women’s perceptions, feelings, and experiences. Meanwhile, evidence shows that a very basic step in care delivery to women with HRP in countries with effective HRP management and low maternal mortality rate is the use of holistic woman-centered approaches. Therefore, healthcare providers need to not only manage HRP-associated physical health problems, but also pay careful attention to pregnant women’s feelings, satisfaction, and well-being.
