Polycystic Ovarian Syndrome: Prevalence, Predisposing Factors, and Awareness Among Adolescent and Young Girls of South India & More Latest News Here – Up Jobs

Polycystic ovarian syndrome (PCOS) is a common endocrine/hormonal disorder that affects women, especially after puberty. Alternatively, PCOS may be expanded as polycystic ovary syndrome. Around 5-15% of women in the reproductive age group suffer from hormonal imbalances that lead to menstrual irregularities, cysts in ovaries, infertility, and other health problems that include cardiovascular complications, type 2 diabetes mellitus (T2DM), and endometrial cancer [1]. PCOS is recognized as an important reproductive as well as a metabolic disorder since it affects the ovaries, and 40% of the affected women suffer from insulin resistance and are subsequently predisposed to developing T2DM [2]. The global prevalence of PCOS is estimated between 4% and 20% [3].

The World Health Organization (WHO) data suggests that approximately 116 million women (3.4%) are affected by PCOS globally [4]. The data on the prevalence of PCOS in India are scarce. According to the National Health Portal of India, the prevalence rate of PCOS in Maharashtra was noted to be 22.5% [5]. Another previous report from South India, which included adolescents, showed an incidence of 9.13% [6]. However, the diagnostic criteria for PCOS were different in those studies.

The reasons for the development of PCOS have not yet been precisely identified. However, some previous studies show that PCOS could be linked to hereditary, lifestyle, and environmental factors that include early age of puberty, premature fetal development, family history of PCOS among first-degree relatives, physical inactivity, stress, and obesity among others [7,8]. It was also identified that the steroidogenic enzyme, cytochrome P450 enzymes (CYPs) related gene polymorphisms (CYP11A1, CYP17A1, and CYP19A1) could contribute to the development of PCOS [7].

Patients suffering from PCOS may present with irregular or anovulatory cycles with signs of hyperandrogenism such as acne, seborrhea, hirsutism, alopecia, and polycystic ovaries on pelvic sonography. Other prominent features that PCOS patients show include weight gain and mood swings [6]. PCOS among adolescents and young girls is generally undiagnosed and underreported. Moreover, untreated patients develop complications such as infertility, pregnancy-related issues, metabolic disorders, and cardiovascular diseases [9,10]. PCOS patients have an increased chance of developing impaired glucose tolerance and suffer from T2DM. Also, an association of PCOS with gynecological cancers should be considered a cause for serious concern [11].

The diagnosis of PCOS can be performed by using various guidelines/criteria as recommended by the National Institute of Health (NIH), Rotterdam criteria, and the Androgen Excess PCOS Society (AE-PCOS) criteria [12]. Recently, the international evidence-based guidelines suggested that the Rotterdam criteria are superior to others in diagnosing PCOS [13]. Due to a lack of awareness, many menstrual problems including PCOS remain unidentified and untreated, especially among the rural population. Such patients fail to conceive and present themselves at fertility clinics. Therefore, it is increasingly important to improve awareness among females at an early age, which potentially contributes to early diagnosis and prevents late sequelae of PCOS [14].

This prospective study was carried out to assess the prevalence and knowledge of PCOS among adolescents and young girls. An informative briefing on PCOS was used to improve the basic knowledge of PCOS, and a questionnaire-based survey (pre- and post-test) was carried out to identify the level of knowledge, barriers to awareness, complications, and potential predisposing factors for the development of PCOS.

A prospective study was conducted between July and August 2019 and included 250 young and adolescent girls attending schools and colleges in and around Vikarabad, Telangana, India. All the participants of the study were explained the procedure and informed consent was obtained. The study was approved by the Institutional Ethics Committee of Mahavir Institute of Medical Sciences, Telangana, India. Convenient sampling was applied to recruit adolescent and young girls aged 13-19 years and 20-25 years, respectively. Females aged less than 13 years and more than 25 years were excluded from the study.

Data collection procedure

The data were collected in the form of pre-validated questionnaires designated as pre- and post-test questionnaires. The pre-test questionnaire was applied to collect data including sociodemographic details, information regarding awareness of PCOS, causes or predisposing factors, symptoms, complications, and measures to be taken to prevent PCOS. Thirty-minute chalk and board teaching methodology was used along with some charts of the reproductive system to explain the keynotes and provide information regarding PCOS. All the study participants actively participated in the session, which was interactive, wherein questions and doubts raised by the participants were addressed.

A post-test questionnaire was used to assess the perception of students regarding the effect of awareness programs on students’ satisfaction and knowledge, reasons for barriers to the lack of awareness, and suggestions for increasing awareness.

Statistical analysis

The data collected were systematically entered into a Microsoft Office 2019 Excel sheet (Microsoft® Corp., Redmond, WA), and were used to prepare tables and calculate the mean and percentage. The data collected were processed using statistical software SPSS 11.0 (IBM Corp., Armonk, NY), and the chi-square test was applied to find out the significance of the results.

The mean age of the study participants was 16.95 years. Among them, the majority were adolescents (78.8%) followed by young girls (53%). Of the participants included in the study, 35.6% were high school girls, 16% were junior college girls, 28.4% were non-medical undergraduates, and 20% are medical undergraduates. The BMI was found normal in 78% of study participants, 17.6% were underweight, and 4.4% were noted to be overweight. The sociodemographic details and other aspects of the study participants are shown in Table 1.

Only 54 (21.6%) study participants were aware of the term PCOS, and 6.8% had already been diagnosed and were receiving treatment for PCOS. Among the study participants who were aware of PCOS, the majority acquired information through teachers (37%), followed by doctors (31.5%), the internet (11.1%), and other sources (12.9%), and a few participants collected information from friends (7.5%). The awareness of PCOS was more among young women (84.9%) as compared to adolescent girls (4.5%). Similarly, participants who were pursuing undergraduate (both medical and non-medical) degrees had higher awareness levels (92%) as compared to the pre-university girls (2.5%). A pre- and post-test comparison of awareness among the study participants regarding the potential reasons for developing PCOS is delineated in Table 2.

The awareness levels of the study participants regarding the symptoms of PCOS along with the pre- and post-test comparisons are delineated in Table 3.

The awareness levels of the study participants regarding the complications of PCOS along with the pre- and post-test comparisons are delineated in Table 4.

The awareness levels of the study participants regarding the measures required to prevent PCOS along with the pre- and post-test comparisons are delineated in Table 5.

The reasons for the lack of knowledge and the barriers to information regarding PCOS included lack of information (45.2%), no advertisements (18%), and social stigma (5.6%), among others, as shown in Table 6.

The study participants suggested that conducting surveys (28%), awareness programs (22%), campaigns (4.4%), advertisements (3.6%), and seminars (2%) could improve the knowledge and awareness of PCOS among the susceptible populations.

PCOS is one of the major endocrine diseases of concern among women. PCOS results in hormonal, gynecological, metabolic, and cosmetic disorders. It was first described by Stein and Leventhal in 1935 among women, and the prevalence ranges between 5% and 15% depending on the criteria applied to diagnosis [1].

According to the International Classification of Diseases (ICD), PCOS is a complex disease that manifests as infertility, hirsutism, obesity, and menstrual disturbances such as oligomenorrhea, amenorrhea, and anovulation. PCOS is associated with bilateral enlarged ovaries studded with atretic follicles and evidence of fluid-filled cysts as identified by ultrasound scanning [15].

Mechanisms involved in the development of PCOS and associated complications

The mechanisms underlying the development of PCOS and complications associated with it appear to be influenced by several factors. Elevated activities of testosterone were found among the patients suffering from PCOS. This may contribute to the reduced activities of follicle-stimulating hormone (FSH) and disrupt the function of ovaries. Hyperandrogenism also causes hirsutism, elevated insulin secretion, glucose intolerance, dyslipidemia, and T2DM. The hormonal imbalances occur due to the disturbed hypothalamic-pituitary-ovary axis and result in menstrual irregularities, anovulation, and infertility. Most patients who developed PCOS had a genetic predisposition [7]. Moreover, environmental factors, food, and lifestyle were influential in the development of PCOS and associated complications [3].

Currently, PCOS has no definite cure, but the associated comorbidities can be addressed to improve the quality of life and minimize the long-term complications associated with PCOS. The metabolic disturbances worsen with time, and the prognosis becomes poor gradually over time. The time lag between the appearance of symptoms and diagnosis of PCOS needs to be lessened to reduce the deleterious effects that include infertility, impaired glucose tolerance, insulin resistance, obesity, cardiovascular complications, and endometrial cancer, among others. Moreover, PCOS also affects the health of post-menopausal women, as evidenced by the increased occurrence of obesity and T2DM among postmenopausal women with PCOS as compared to others [11,16].

A timely diagnosis of PCOS in symptomatic adolescent girls is important for the initiation of appropriate treatment and management initiatives. However, this can be achieved by spreading awareness through educational interventions and other measures such as educating the susceptible population regarding the symptoms, etiology, age of onset, and PCOS-related health care services [14].

The present study included the majority of adolescents, and the awareness among them was critically poor when compared to the young girls in the age group of 20-25 years who had a better knowledge of PCOS. This probably might be due to less exposure to society, i.e., the parents of the participants belonging to rural backgrounds restrict their social behavior. This, in a long run, could have created stigma regarding the expression of their enthusiasm toward the physical and mental transformations occurring after menarche.

In our study, the participants were briefed on the facts of PCOS, and an effort was made to explain them logically. Enlightening the age group of 13-19 years was found to be more fruitful compared to the young girls, probably due to rigid perceptions in the latter group.

A 21.6% awareness was observed in the current study, which was on the lower side in contrast to the results obtained in a study from Indore, central India, as reported by Patel and Rai who reported an awareness level of 41% [17]. This suggests that the women in the age group of >18 years, who are studying in colleges, and working women might have acquired knowledge regarding PCOS through socializing, news, media, workshops, conferences, etc. Another study by Rajkumari et al. from Orissa, East of India, reported 22% awareness, a similar finding to our study results [18]. The reason could have been the inclusion of rural and semi-urban populations. A study conducted among non-medical undergraduates in Dhaka, Bangladesh, revealed that more than 50% of the participants had knowledge of PCOS, which was significantly higher than our result [19]. This might be due to the rural background of our participants who had restricted access to information.

Most study participants were unaware of the symptoms of PCOS and that this condition may result from genetic reasons and can possibly be inherited from parents and predisposing factors for the development of PCOS including obesity, among others. The majority believed that hormones and their imbalances are related to the development of PCOS and that symptoms such as irregular menses, mood swings, hirsutism, and hair loss could be attributed to PCOS. Most participants were aware that infertility and abortion could be long-term sequelae associated with PCOS. However, they were not aware of the association of PCOS with cardiovascular complications, diabetes, and gynecological cancers. The awareness regarding symptoms and complications of PCOS was significantly increased after the educational intervention done in our study. Knowledge about healthy diet and physical activity/exercise and their beneficial effect on the prevention and management of PCOS was noted among the study participants, a finding similar to that reported in a previous study by Pitchai et al. from Mumbai, India [20].

Teachers and doctors were noted to play a key role in the dissemination of information regarding PCOS. It was found that the level of education positively correlated with the levels of awareness. The highest awareness percentages were noted among medical undergraduates followed by non-medical graduate students.

Limitations

The PCOS prevalence rates observed in this study do not necessarily reflect the real prevalence. A selected age group of participants were enrolled (adolescents and young girls), and other women, of different ages, and those who reached menopause were excluded from the study. Also, the diagnosis of PCOS among the study participants was not performed based on definitive diagnostic criteria. The inclusion of limited subpopulations and subgroups from a defined geographical area could have contributed to bias in the results obtained from this study.

PCOS is a common problem encountered by females after attaining puberty. Most study participants were unaware of the symptoms and management of the condition. Therefore, the disease burden noted in this study does not necessarily depict the real prevalence. PCOS is an endocrine disease associated with hormonal imbalances wherein women suffer from hyperandrogenism and increased activities of testosterone. PCOS presents as irregular menstruation, anovulation, and/or polycystic ovaries. It affects women of all age groups, and the knowledge of PCOS is essential to efficiently manage the condition and minimize the long-term complications associated with it like insulin resistance, glucose intolerance, diabetes, cardiovascular disease, and endometrial cancers, among others. However, the prevalence of PCOS and the knowledge of symptoms, complications, prevention, and management of this condition are highly variable in different geographical regions and population groups. Owing to the complexity of the disease, its presentations, and potential complications, efforts should be made by the governments to increase its awareness, especially among the rural and low socioeconomic populations.
