INTRODUCTION
The association between hypertension and pregnancy is frequent1. Regarding the epidemiological context, hypertensive disorders during pregnancy affect about 10% of all pregnant women worldwide1-2. In developed countries, this incidence varies between 2 and 8%, lower than in developing countries, such as Brazil, which can have rates above 10%3).
This group of hypertensive disorders includes preeclampsia and eclampsia, gestational hypertension and chronic hypertension, being an important cause of severe acute morbidities, long-term disabilities and even death of mothers and babies2.
The diagnosis of hypertension during pregnancy is made when blood pressure levels are 140/90 mmHg or higher. It can be classified as preeclampsia when hypertension arises after the 20th week of gestation associated with proteinuria; as chronic hypertension, when identified before pregnancy or before the 20th week; and preeclampsia on chronic hypertension, when the patient has previous hypertension and proteinuria after the 20th week of pregnancy1.
Hypertension in pregnancy is also called Gestational Hypertensive Syndrome (GHS), a term used in this study to characterize this health condition, whose complications increase the incidence of morbidity and mortality and, together with infections and hemorrhages, are among the three main causes of maternal death in Brazil4.
It is important to highlight risk factors that increase the likelihood of developing GHS, such as diabetes, kidney disease, obesity, multiple pregnancy, primiparity, age over 30 years, personal and/or family history of preeclampsia, chronic hypertension and ethnicity5.
Prenatal care is one of the fundamental actions for the prevention and treatment of GHS, positively impacting maternal and child health indicators. Thus, the main objective of prenatal and puerperal care is to provide medical attention for women from the beginning of pregnancy, ensuring a healthy end of pregnancy and childbirth and guaranteeing maternal and neonatal well-being6.
Therefore, knowledge of the epidemiological profile, centered on the socioeconomic, demographic and obstetric characteristics of pregnant women with GHS, favors the planning of prenatal care, the early identification of the disease and the development of a therapeutic plan for the appropriate follow-up of high-risk pregnant women.
Nurses plays an important role in the care of hypertensive pregnant women, since they are capable of directing care to their clinical needs, thus improving the quality of care and, consequently, preventing complications caused by this problem. This study aims to describe the socioeconomic, demographic and obstetric profile of pregnant women with GHS and to verify correlations or associations between the variables.
METHODS
Descriptive, correlational and exploratory study, derived from the thesis entitled “Effect of an educational intervention for the prevention of complications of GHS: a randomized clinical trial”, conducted in a maternal-fetal public tertiary care unit, located in a municipality in northeastern Brazil, reference in the care of high-risk pregnant women.
Pregnant women with medical diagnoses of GHS participated in the study. The age of the participants was not considered as a criterion. The criteria were: to be literate and have ability for verbal communication in the Portuguese language. Exclusion criteria were: gestational age greater than 33 weeks. This criterion was adopted because the development of the randomized clinical trial required two post-test applications after the intervention. The first post test was applied seven days after the intervention and the second was applied 30 days after. The limit considered for participants to go into labor was 38 weeks of pregnancy, to prevent sample loss. The sample consisted of 120 pregnant women.
Data were collected from November 2017 to April 2018, through interviews that used a questionnaire composed of objective questions developed by the researchers. Data collection was performed after the Informed Consent Form was signed.
The quantitative variables of the study were: age, educational level, family income, Body Mass Index (BMI), Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP), number of prenatal consultations for the current pregnancy and previous pregnancies, childbirths, and abortions. The categorical variables of the study were: religion, skin color, employment, marital status, age group, educational level group, family income group, and type of hypertension diagnosis (chronic or gestational).
The family income, age and educational level groups were categorized using the median as cutoff point. BMI was categorized as: category I - overweight (25 - 29.99), obesity I (30 - 34.99); obesity II (35 - 39.99) and III (over 40).
Descriptive statistics were performed considering absolute (n) and relative (%) frequency results for the categorical variables. Data for quantitative variables were analyzed considering the means, standard deviation, median, minimum and maximum values.
The nonparametric Mann-Whitney U test was used for analytical statistics of association between quantitative and categorical variables, according to an abnormal distribution assessed by the Shapiro-Wilk test. P-values less than or equal to 0.05 were considered significant.
The article was approved by the Research Ethics Committee (CAAE: 69789617.5.0000.5404) on October 2, 2017, in compliance with the ethical standards of Resolution 466/127.
RESULTS
Among the 120 pregnant women with GHS, 73 had a diagnosis of chronic arterial hypertension (60.83%) and 47 (39.17%) of gestational hypertension. The socioeconomic, demographic and obstetric conditions of pregnant women with GHS are shown in Tables 1 and 2.
No significant differences were observed between BMI categories regarding SBP, DBP, educational level, family income and history of deliveries (p> 0.05). However, significant differences were found regarding the number of prenatal consultations during the current pregnancy (p = 0.026), previous pregnancies (p = 0.008), abortions (p = 0.017), and age (p = 0.002) (Table 3).
In the comparisons between age groups, there was no statistical significance in relation to SBP, DBP, family income and the number of prenatal consultations of the current pregnancy (p> 0.05). But significant differences were found regarding educational level (p = 0.043), history of pregnancies (p = 0.001), deliveries (p = 0.001), abortions (p = 0.004), and BMI (p = 0.026) (Table 3).
When compared to the educational level categories, no significant results were identified regarding SBP, DBP, number of prenatal consultations of the current pregnancy, abortions, BMI, and age (p> 0.05). Regarding the history of pregnancies (p = 0.010), childbirth (p = 0.001) and family income (p = 0.007), significant differences were observed (Table 3).
By analyzing the Mann-Whitney U test results, regarding family income categories, a significant difference was evidenced only in relation to educational level (p = 0.043). Regarding employment, a significant difference was observed in relation to the family income (p = 0.002). For comparisons regarding marital status, a significant difference regarding DBP was evidenced (p = 0.013).
Considering the type of gestational hypertension, it was observed that women with chronic hypertension were older (p = 0.0024), with a mean age of 32.47 ± 6.69 years, while the mean age of the others was of 28.57 ± 6.74 years, and they had a lower gestational age (p = 0.0219) and a higher number of abortions (p = 0.0140).
DISCUSSION
It is relevant to consider that pregnancy develops in a sociocultural context that determines its evolution and trajectory in healthcare. Considering this, it is also appropriate to point out aspects such as obstetric history and socioeconomic and demographic variables to know the risk factors that may interfere with maternal and fetal health assistance and so guide the care8.
In this study, 120 pregnant women diagnosed with GHS were interviewed. Most (59.2%) declared themselves to be Catholic, 70.8% had brown skin color, 60% were employed, 75.8% were in a stable union, 50% were aged 32 to 46 years, 87.5% had up to 11 years of schooling, and just over half (50.8%) had a family income of up to R$ 954.00. These findings are in accordance with the profile of high-risk pregnant women evidenced in other national studies8-9.
The recommendations of the Ministry of Health for high-risk pregnancies10, as well as the principles of the Prenatal and Birth Humanization Program11 and the Cegonha Network12, suggests that pregnant women should have clinical and obstetric aspects evaluated often for early and appropriate identification of situations that may lead to complications to the development of pregnancies and, when found, refer the pregnant woman to high-risk prenatal care.
Regarding the obstetric profile, 50% of the women had a BMI of obesity II and III, SBP average of 129.86 ± 16.43 mmHg and DBP of 81.08 ± 13.28 mmHg, had a mean of 5.29 ± 2.70 prenatal consultations for the current pregnancy and average history of 2.77 ± 1.72 pregnancies, 1.18 ± 1.39 deliveries and 0.55 ± 0.98 abortions. These findings converge with other researches, showing obstetric factors as risk factors for the development of GHS. It is important to note that all participants evaluated had a diagnosis of GHS.
Regarding marital status, occupation and educational levels, the study corroborates a research conducted with high-risk pregnant women, which showed 52% of married respondents and 64% with complete high school (11 years) 4, but disagreed regarding occupation, as 60% of the interviewees were employed. Previous studies show a higher prevalence of housewives13-14.
Among these variables, the years of formal schooling deserve attention, since a lower time studying may represent a risk factor for one of the complications resulting from GHS15, as it is related to the lower access to information and the limited understanding of the importance of healthcare actions, especially regarding the prevention of early pregnancy and prospective history of multigestation, since significant differences in these variables were evidenced among those with lower educational levels.
The sample of this research can be characterized as vulnerable, due to the shorter time of schooling and family income, which makes it representative of the population attended by the public health service. It is noteworthy that unsatisfactory socioeconomic conditions may increase the risk of problems during pregnancy, since they are usually associated with greater stress and poor nutritional conditions16.
Regarding nutritional status during pregnancy, half the pregnant women reported being overweight, and there were significant differences, among those with lower BMI, with regards to the number of prenatal consultations of the current pregnancy, previous pregnancies, abortions, and age. Both maternal nutritional status and gestational weight gain have been the focus of several studies, due to the increasing prevalence of eating disorders, as well to the essential role of gestational outcomes. Maternal obesity influences maternal health, gestation time, and possible pre- and postpartum complications (16.
Among the 120 pregnant women, half were older than 35 years of age, corroborating a previous study13. Women aged 35 years old or older are generally susceptible to adverse perinatal outcomes and maternal morbidity and mortality, since they are considered to be late pregnancies. Thus, studies show that due to ovarian senescence and the increased frequency of chronic diseases in women in this age group, as pregnancy is delayed, women are more likely to be susceptible to various risks17-18. It was noticed that, among the interviewees, the educational level and the history of pregnancies, births, abortions and BMI were different between younger and older women. The group of pregnant women with chronic hypertension was older than 30 years, which is in agreement with the literature5.
Longitudinal and population-based studies are needed to better define the risks associated with the occurrence of GHS in pregnant women assisted not only in the public service but also in the private sector. Identifying and controlling these factors as early as possible may reduce the impact of possible gestational complications.
Knowing the profile of pregnant women with GHS is important for professionals, especially those working in prenatal care, to direct actions for early diagnosis and prevention of major mother and newborn complications that GHS can cause during and after pregnancy.
Therefore, professionals must identify early the risk factors for GHS, enabling benefits for one of the most prominent public health sectors, which is currently targeted for maternal and neonate healthcare programs, thus reducing the mortality rates of mothers and children.
CONCLUSIONS
The group of pregnant women with GHS had a mean age of 30.9 years, social vulnerability, and overweight or obesity. Considering the type of arterial hypertension, pregnant women with chronic arterial hypertension are older and have a higher number of abortions.
The limitation of this study was its methodological design. The descriptive and exploratory design made it impossible to contribute to evidence GHS risk factors, limiting the study within the proposed descriptive setting. However, it is important to highlight that the results found can contribute to health services, since the information yielded can direct actions, especially during the prenatal consultation.
Thus, the results of the present study highlight the importance of knowing and analyzing the sociodemographic and obstetric data of the population in order to enable guided assistance in the promotion of healthy prenatal, delivery, and puerperium.
