Knowledge and attitudes on anemia and menstrual health among Malaysian female university students

Anemia is a significant public health concern, particularly among young female adults due to its potential impact on reproductive health. This study investigated the association between anemia-related knowledge, attitudes, menstrual health, and anemia status among Malaysian university students. This was a cross-sectional study named “SCARF” - Study to Combat Anemia - Research for Female Students, involving 674 university students in Malaysia. Anemia status was determined based on haemoglobin level, while knowledge, attitude and menstrual health were measured using validated questionnaires. The mean menarche age of students in this study was 12.1 ± 1.21 years. Students who were anemic had significantly longer menstrual cycle duration (P = 0.034) and more days with heavy flow (P = 0.038). Most students had poor knowledge (44.5%) and attitudes (84.1%) towards anemia. Students with good knowledge were 1.1 times more likely to have better anemia status compared to those with poor knowledge (95% CI: 1.0–1.2, P = 0.049). This study highlighted a lack of practical application of the knowledge to dietary habits. Collaborative efforts between educators and healthcare providers are crucial in developing a comprehensive strategy, such as interventions to prioritise educational initiatives and practical support to enhance overall menstrual health among female students.

Age at menarche by birth cohort: A pooled analysis of half a million women in Asia

ObjectivesTo evaluate changes in the age at menarche in Asian populations. Study designRetrospective cohort study. MethodsWe included 548,830 women from six countries in Asia. The data were sourced from 20 cohorts participating in the Asia Cohort Consortium (ACC) and two additional cohort studies: Japan Multi-institutional Collaborative Cohorts (J-MICC), and Japan Nurse Health Study (JNHS) with data on age at menarche. Joinpoint regression was used to evaluate changes in age at menarche by birth year and by country. ResultsThe study includes data from cohorts in six Asian countries namely, China, Iran, Japan, Korea, Malaysia and Singapore. Birth cohorts ranged from 1873 to 1995. The mean age of menarche was 14.0 years with a standard deviation (SD) of 1.4 years, ranged from 12.6 to 15.5 years. Over 100 years age at menarche showed an overall decrease in all six countries. China showed a mixed pattern of decrease, increase, and subsequent decrease from 1926 to 1960. Iran and Malaysia experienced a sharp decline between about 1985 and 1990, with APC values of −4.48 and −1.24, respectively, while Japan, South Korea, and Singapore exhibited a nearly linear decline since the 1980s, notably with an APC of −3.41 in Singapore from 1993 to 1995. ConclusionsOverall, we observed a declining age at menarche, while the pace of the change differed by country. Additional long-term observation is needed to examine the contributing factors of differences in trend across Asian countries. The study could serve as a tool to strengthen global health campaigns.

Association between Changes in Menarcheal Age and Adolescent Idiopathic Scoliosis: An Analysis of 38,879 Patients over 20 Years.

Menarche has a significant impact on the progression of adolescent idiopathic scoliosis (AIS); however, studies in this area are insufficient. This study used large-scale school screening data to investigate the relationship between menarcheal age and AIS, especially the severity of scoliosis. Of 2,326,577 students who participated in school screening for scoliosis (SSS) in South Korea from 2001 to 2021, 38,879 girls with AIS, who experienced menarche, were included. Data including the patient's demographics, such as menarcheal age, Cobb angle, Risser stage, and the interval between menarche and the time of screening were retrieved from the SSS database. Pearson correlation coefficient was used to identify the changes in menarcheal age according to the birth year and to investigate the relationship between menarcheal age and each variable of interest. Based on the birth year, the mean menarcheal ages in girls with AIS from 1988 to 2008 demonstrated a steadily decreasing trend over time (r = -0.857, p < 0.001). Girls with AIS and late menarche demonstrated a higher Cobb angle at the time of screening (r = 0.095, p < 0.001). Other variables did not significantly correlate with menarcheal age. Based on the SSS, a large-scale school screening dataset, menarcheal age in girls with AIS demonstrated an ongoing downward trend in the recent 20 years in South Korea. Notably, girls with AIS and late menarche had a higher Cobb angle at screening. Our findings indicate the need for earlier screening of AIS in girls who have not undergone menarche.

Menstrual health and hygiene practices of adolescent girls attending school in rural parts of South India and its effect on school attendance in the year 2020: A Descriptive Cross-Sectional Study

Background: Menstruation is a normal and natural process that occurs during a female’s reproductive years, misperceptions surrounding menstruation, which can negatively impact the mental, emotional, and physical health of adolescent girls, as well as their academic performance. Our objective was to describe the menstruation practises among rural school going adolescent girls and its effect on school attendance. Materials and Methods: In the present descriptive and cross-sectional study included 495 students from government and government-aided schools a total of 7 schools. Results: Almost 90% of the girls had regular periods, 59% of these girls’ attained menarche at the age of 13 – 15 years. Out of these students 9% of them skip school frequently during menstrual period due to pain, 3% skip school due to excessive bleeding, and the rest skip school during this period either due to parent’s beliefs (1%) or because they think the sanitation facility at their school is not adequate (0.2%). Conclusion: The mean age of menarche in our study was 12.6, on an average the girls had 35 days of periods, with 5 days of menses, close to 99% of the girls used sanitary pads but most of them did not obtain it from schools, and 13% of girls had been absent often during their menstrual period.

The effect of psychological stress on the menstrual cycle among medical students.

To assess the prevalence of menstrual abnormalities among medical students, and to explore its association with stress levels. TThe cross-sectional study was conducted from May 18 to May 28, 2021, in Baghdad, Iraq, after approval from the ethics review committee of the College of Medicine, Mustansiriyah University, Baghdad, and comprised female medical students in Baghdad. Data was collected using simple random sampling technique and employed an online questionnaire that was distributed through e-mail. The questionnaire had 3 domains: demographic and anthropometric data, menstrual history, and psychological stress. The psychosocial stress levels was assessed using the Perceived Stress Scale-10. Data was analysed using SPSS 25. There were 397 subjects with mean age 20.84±1.621 years (range: 17-24 years). Mean age of menarche was 12.65±1.399 years, mean body mass index was 22.71±6.369kg/m2 and the mean stress score was 22.71±6.016. Dysmenorrhoea was seen in 369(92.9%) cases, and premenstrual symptoms in 391(98.5%). Dysmenorrhoea, premenstrual syndrome and heavy bleeding were significantly associated with stress level (p<0.05). Most students had heavy bleeding and dysmenorrhoea, which were severe enough to require analgesics. There was a significant association between high stress levels and the occurrence of menstrual abnormalities.

Current trend of sexual maturity, teeth eruption, and bone fusion in the present female population, relative to documented age and development of prediction model for age of females.

Understanding sexual maturity and bone fusion is crucial in forensic investigations and legal contexts. This study investigates the contemporary trend of sexual maturity and bone fusion in females, comparing the observed age-related characteristics with documented ages. Such analyses contribute to the accuracy of age estimation methods used in medico-legal scenarios. A comprehensive study was conducted involving a diverse sample of females, and their sexual maturity and bone fusion were assessed relative to documented ages. The research utilized a cross-sectional design, collecting data through interviews, medical examinations, and radiographic imaging. Ethical approval was obtained, and participants provided informed consent. Variables included documented age, age of menarche, stages of sexual maturity, dentition, and bone fusion. Validation of model performance was conducted. Among 70 cases studied, the mean age of menarche was 10.48 years (range: 7-12 years). Maternal reports indicated menarche onset between 12-17 years. Tanner's Staging 5 for pubic hair and fully developed breasts occurred at 14 years. Permanent teeth increased with age, with 28 or more teeth present at age 14 or above. Fusion of the distal end of the Radius and Ulna with the parent bone was positive from 15 years onwards. The regression model predicted age accurately (97.99% fit). The results highlight the early onset of sexual maturation, consistent teeth eruption, and bone fusion patterns in females. The observed correlations offer valuable insights for medicolegal practitioners and forensic experts.

Factors associated with age at menarche, menstrual knowledge, and hygiene practices among schoolgirls in Sharjah, UAE

ABSTRACT Age at the onset of menarche is affected by several factors. However, the characterization of such factors in the United Arab Emirates (UAE) remains partly elusive. We investigated the factors influencing the mean menarcheal age in schoolgirls from Sharjah, UAE. We also evaluated the menstrual knowledge and hygiene practices in the study population. We recruited 410 schoolgirls aged 8–17 years in this cross-sectional study. Data were obtained via a self-administered questionnaire. The mean age at menarche was 11.5 years (±1.17 SD) in the study population. A significant correlation was found between lower household income and delayed age at menarche (p = 0.005). Students who were less than 12 years old attained menarche earlier than older students (p = 0.001). Among the participants, 57.7% had good knowledge about menstruation and 54.7% adopted adequate hygiene practices. The mean age at menarche in the UAE is lower than in other Gulf regions. Earlier implementation of menstrual education programmes at schools is recommended.

Temporal trend of age at menarche in Korean females born between 1927 and 2004: a population-based study.

The age at menarche has decreased worldwide. Previous studies on Korean adolescents have reported a downward trend in age at menarche. This study aimed to investigate the current trends in age at menarche among Korean adolescents using nationally representative data. The study used data from the Korea National Health and Nutrition Examination Survey 2007-2021. A total of 50,730 females born between 1927 and 2004 with information on age at menarche were included. The trend in age at menarche was analyzed according to 15 birth-year groups (with 5-year intervals) using quantile regression analysis. The mean age at menarche decreased from 16.92 ± 0.06 years for females born before 1935 to 12.45 ± 0.04 years for females born between 2000 and 2004 (p <.001). According to the percentile group of age at menarche, mean menarche age decreased by -0.071 years per year (95% confidence interval [CI], -0.072 to -0.070) in total, -0.050 years per year (95% CI, -0.052 to -0.048) in the 3rd percentile group, -0.088 years per year (95% CI, -0.091 to -0.085) in the 97th percentile group (p <.001 for all). A decreasing trend of age at menarche was more prominent in the obesity group (-0.080 years per year, 95% CI, -0.082 to -0.078) compared to the non-obesity group (-0.069 years per year, 95% CI, -0.071 to -0.068) (p <.001 for both). Ongoing downward trend in age at menarche was observed in Korean females born until 2004, decreasing by 0.71 years per decade. The downward trend was faster in individuals with a higher percentile of age at menarche and in those with obesity.

Endocrine effect of phthalate metabolites and a butterfly effect of prenatal exposure to androgens on qualitative aspects of female sexual response- an initial survey.

There is growing evidence that endocrine disruptive chemicals have deleterious effects on sexual and reproductive function. To examine subjective sexual functions in human females and their relationship to postnatal phthalate exposure and perinatal androgenization, a Sexuality Score (SS) was established from a first-stage survey questionnaire of subjective sexual function filled out by female university students (n = 68; average age 25.23 ± 5.17 years; rural 25.51 ± 6.74 vs. urban 25.85 ± 1.43 years). Seventeen phthalate metabolites in urine samples were analyzed by high-performance liquid chromatography (HPLC) and tandem mass spectrometry (MS/MS). Females were also assessed for the 2D:4D digit ratio as an index of perinatal androgenization. The mean age of menarche was 12.82 ± 1.35 years (rural 12.59 ± 1.39 vs. urban 13.18 ± 1.27; p = 0.01). The mean age at first sexual intercourse was 14.88 ± 6.89 years (rural 14.62 ± 7.20 vs. urban 15.24 ± 6.55), and as the age of first sexual intercourse increases, the SS score tends to increase as well, albeit moderately (r = 0.25, p = 0.037). Mono-iso-butyl phthalate, mono(2-ethyl-5-carboxypentyl) phthalate, mono(hydroxy-n-butyl) phthalate, mono(2-ethyl-5-oxohexyl) phthalate (p ≤ 0.05) and mono(2-carboxymethylhexyl) phthalate (p ≤ 0.01) were negatively associated with SS. A compounding butterfly effect of prenatal exposure to androgens was observed with disruptive effects of mono(2-ethyl-5-oxohexyl) phthalate and mono(2-ethyl-5-carboxypentyl) phthalate on sexual function. Exposure to phthalates in adult females may lead to disruption of subjective sexual function, especially concerning sexual desire and sexual satisfaction, and perinatal androgenization could augment these effects.

The state of the reproductive system of adolescent girls after vaccination against human papillomavirus using a quadrivalent vaccine

Background. Currently, oncological diseases and their possible prevention are being actively studied. Cancer mortality remains high. A national project “Healthcare” has been started in Russia, including the Federal projects “Fighting Cancer” and “Development of Children’s Health Care, including the creation of a modern infrastructure for providing medical care to children”. In a number of regions, girls can be vaccinated against the human papillomavirus (HPV). The main reason for refusing HPV vaccination is an unfounded fear of negatively affecting the fertility and other bad data. The aim of the study is an investigation of the reproductive system of adolescent girls with completed course of vaccination against HPV using quadrivalent vaccine. Methods. We selected 65 schoolgirls in Moscow by analyzing medical documentation data. All of them were vaccinated against HPV and examined by a gynecologist. The state of their reproductive system was assessed. Results. Most girls received the vaccine at the age of 12–13, according to the regional vaccination calendar of the city of Moscow. They were vaccinated with the quadrivalent vaccine twice with an interval of 6 months; no adverse event was noted. The mean period of time since vaccination was 2.7 ± 1.1 years. The mean age of menarche, mean menstrual cycle length, and mean bleeding time were normal in girls vaccinated against HPV. Among menstrual disorders, dysmenorrhea and oligomenorrhea were most often observed, but the data did not differ from the population average. The incidence of abnormal uterine bleeding and breast pathology was lower. No papillomas were detected. Pubertal development corresponded to age of all girls. Conclusion. It has been established that vaccination against the human papillomavirus does not have a negative impact on the reproductive system of teenage girls. However, additional dynamic studies are needed at different age periods of girls and women vaccinated against HPV to confirm the positive effect on the sexual sphere and formation of strong adherence to vaccination.

Growth and endocrinopathies among children with β-Thalassemia major treated at Dubai Thalassemia centre

Backgroundβ-Thalassemia major (BTM) is one of the most common hereditary anemias worldwide. Patients suffer from iron overload that results from repeated blood transfusion This in turn leads to multiple organ damage and endocrinopathies. This study aims to assess the prevalence of growth retardation, hypothyroidism, and diabetes mellitus in children and adolescents with BTM treated at Dubai Thalassemia Centre.MethodsA total of 105 children and adolescents were included in this retrospective observational study.Results39 children and 66 adolescents’ data were analyzed. Females composed 51.3% (n = 20) of children and 53.0% (n = 35) of adolescents. Pretransfusion hemoglobin below 9 gm/dl was observed in 10.8% (n = 4) and 10.6% (n = 7) in children and adolescents, respectively. The mean age of menarche was 13.5 years. Among all study participants, 22.6% (n = 14) had normal height velocity whereas 37.1% (n = 23) had reduced height velocity in one year and 40.3% (n = 25) had reduced height velocity in two consecutive years. The proportion of children and adolescents showing reduced height velocity was significantly higher in females compared to the males (90.6% versus 63.3%, respectively, Chi-square = 6.597, p-value = 0.010). Although none of the study participants had diabetes mellitus, 26.1% (n = 12/46) had pre-diabetes. Elevated TSH was observed in 14.7% (n = 5) children and 8.1% (n = 5) adolescents while low FT4 was reported in one child and one adolescent.ConclusionOf all endocrinopathies seen among children and adolescents with BTM, growth delay remains the main concern for this group of patients. Effective treatment is key to further reducing endocrinopathies. Although the sample size is limited, we postulate that the low percentage of endocrinopathies among children with BTM treated at Dubai thalassemia center and the low level of pretransfusion anemia reflect the effective transfusion and chelation at the center.

IJCM_387A: Prevalence of premenstrual syndrome among medical undergraduate &amp; postgraduate female students in central India: a cross-sectional study

Background: Premenstrual syndrome (PMS) is a menstrual disorder that can be described as a group of physical, behavioural, and emotional symptoms that occurs during the last week of luteal phase, which is usually the week before the mensuration. A study on PMS prevalence among different countries worldwide found that 47.8% of women have PMS. PMS is a common problem with symptoms that can negatively affect daily life. Therefore, this study aimed to determine the prevalence of Premenstrual syndrome and its severity among medical undergraduate and postgraduate female students in central India. Objectives: To estimate the prevalence of Premenstrual syndrome among medical undergraduate and postgraduate female students. To assess severity of premenstrual syndrome using the Premenstrual syndrome scale. Methods: A cross sectional study was conducted among 358 participant between the age group of 18 to 45 years. Premenstrual syndrome scale was used to assess the prevalence and severity of premenstrual syndrome. The data was analysed using SPSS software. Results: Age of the study participants range from 20 to 35 years, with mean age of 26.3±4.62 years. The mean age of menarche among participants was 12.8+0.98 years. The prevalence of PMS was 69%. There is a statistically significant association of age at menarche with premenstrual syndrome. Conclusion: The study showed that a higher proportion of medical students had PMS with majority of them having moderate symptoms. Therefore, greater attention needs to be given to PMS as part of healthcare service to improve work-life balance and productivity at work.

Attributes of Menstruation among Young Physical Therapy Female Students of Karachi

The average age of menarche is between 9 to 14 years of age. Menarche is considered a normal milestone of every female's life. This period is supposed like a special period of every girl's life because in this stage girl is converted to the woman's age. Menarche is the indicator sign of a female that is ready to take part in reproduction activity. Objective:To determine the attributes of menstruation among young physical therapy female students of Karachi. Methods: This cross-sectional study was done among 385 young physical therapy female students in Karachi-Pakistan to reveal the age, duration, symptoms, and length of the menstruation cycle. The duration of the study was between June to November 2023. A non-probability purposive sampling technique was used. The validated questionnaire was used from a previous study done in 2016. Data were analyzed through SPSS version 23.0 software. Results: A total number of 385 young females was included in this study. The mean age of menarche revealed 187 (48.57%) found between 11 to 13 years. The regularity of menses was found in 299 (77.66%)participants. The average days of menstruation flow were about 6 to 8 days in 218 (56.62%) of research participants. The average length of the menstrual cycle was 21 to 35 days in 221 (57.40%) while the most common symptom found in research participants was lower abdominal pain in 187 (48.57%). Conclusions:There were significant differences between the characteristics of every young female related to the pattern, duration, age, regularity, and cycle length of the menstrual cycle.

Menstrual cycles and the impact upon performance in elite British track and field athletes: a longitudinal study.

To assess the prevalence of menstrual disorders and the perceived effect of menstrual cycles upon performance in elite athletes. A longitudinal survey in the form of a questionnaire was sent to female track and field athletes at British Athletics every 6 months, over a five-year period between 1st October 2014 and 1st October 2019 in the United Kingdom (UK). 128 athletes completed an average of 4.2 ± 2.9 questionnaires across the study period. The mean age of menarche was 14.2 ± 1.4 years, 13.4 ± 1.3 years and 12.8 ± 1.4 years in endurance, power, and thrower athletes respectively (p < 0.05). Two-thirds (66%; n = 82) reported consistently regular cycles, 30% (n = 37) irregular at some point during the period of observation and 4% (n = 5) were amenorrhoeic. 87 athletes (68%) reported dysmenorrhoea and 40 (31%) menorrhagia. More than three quarters (76.8%; n = 96) described their cycle negatively affected performance. Amongst those who reported when the negative impact occurred (n = 91), 40% (n = 36) reported this in the late luteal phase and 35% (n = 32) during the early follicular phase. 79% (n = 100) of athletes reported at least one cyclical symptom, of which bloating, lower back and pelvic pain were most frequently experienced. This data highlights the complex interrelationship between women's health and elite athletic performance. Athletes perceive a negative impact from their menstrual cycles upon performance with a desire to manage these more effectively, particularly during competition. Female reproductive health expertise in the multi-disciplinary management of elite athletes is required.

Correlation Between the Pre and Post Menstrual Symptoms and Body Mass Index Among Females Aged Between 18-25 Years

BACKGROUD AND OBJECTIVE: Menstruation is the cyclical and periodic loss of progestational endometrium and blood. Menorrhagia, Amenorrhea, dysmenorrhea, vomiting, mood changes etc., are common forms of pre and post menstrual diseases. The aim of the study was to assess the relationship between pre and post menstrual symptoms and BMI in females aged between 18-25 years. METHODOLOGY: A total of 100 females aged 18 to 25 years volunteered to participate as subject in this study according to the inclusion and exclusion criteria. The descriptive data like age, weight, height, hip waist ratio and abdominal circumference were collected from each subject after initial brief explanation of the study and written informed consent. The subjects were selected for the study by using a pre designed questionnaire which evaluate the pre and post menstrual symptoms and other factors. Data were analysed by SPSS 21.0 and all the quantitative descriptive data were expressed in mean and standard deviation, and quantitative data expressed in percentage. RESULTS: Among 100 individuals considered for the study, mean age of menarche was 13.22 ± 1.14 years, waist hip ratio 0.74 ± 0.05, abdominal circumference 31.25 ± 3.44 and pain 7.05 ± 1.63. In the study respondents were experiencing abdominal cramps, mood swings, leg cramps, breast tenderness, vaginal discharge, headache, vomiting, giddiness and diarrhea as premenstrual symptoms. And respondents were experiencing dysmenorrhea, menorrhagia, oligomenorrhea, amenorrhea as post menstrual symptoms. CONCLUSION: The present study concluded that there was no statistically significant correlation between the pre and post menstrual symptoms with BMI. Keywords: BMI, Menstruation, Dysmenorrhea, Menorrhagia, Oligomenorrhea, Waist- hip ratio, Amenorrhea, Height, Weight, Menstrual cycle

Menstrual health affecting school absenteeism during menstruation among adolescent girls in Nepal

Background: Girls' adolescence characterized by the multiple changes and the significant one is the initiation of menarche. Despite being the natural regular normal process, there are some menstrual abnormalities female adolescents may encounter in their life. Inability to manage those anomalies efficiently can affect physical, psychological and emotional well-being, including their education because of school absenteeism. Objective: The main aim of the study is to assess characteristics of menstruation and examine its association with school absenteeism among adolescent girls of Nepal. Methodology: A quantitative, community based cross sectional analytical study was conducted among 317 adolescent girls who had already experienced menstruation in 11 different study sites. The questionnaire was self-administered to adolescent girls which was collected on the same day of data collection. Collected data were entered in Epi-data version 3.1 which was further imported to SPSS for further analysis. Logistic regression analysis was used to examine association between school missed due to menstruation and menstrual characteristics. Results: The study showed that the mean age of menarche is 12.9±0.97 years. The majority of adolescent girls (89.6%) have normal length of menstrual cycle where as 42.0% of them had moderate amount of bleeding and 35.3% of them had irregular menstruation cycle. Concerning the menstrual symptoms, adolescent girls experienced depressed mood (30.6%), rapid mood change (24.0%), and dizziness (15.31%). Almost half (46.7%) of adolescent girls had missed school due to menstruation. Dysmenorrhea, (AOR=1.75, 95% CI=1.08-2.83) experience of lower back pain (70.8%, AOR=2.81, 95% CI=1.11-7.10) and dizziness (72.0%, AOR=2.82, 95% CI=1.12-7.10) and use of clothes as absorbent (50.6%, AOR=1.87, 95% CI=1.04-3.38) during menstruation were found significantly associated with missing school during menstruation. Conclusions: Majority adolescent girls have normal menstruation but still there are many girls experiencing varies menstrual issues which influence school absenteeism during menstruation.

Risk Factors Of Ovarian Cancer Among The Postmenopausal Women

Background: Ovarian cancer ranks 5thin cancer deaths among women. A woman’s risk of getting ovarian cancer during her lifetime is about 1 in 75. Cancer mainly develops in older women.&#x0D; Methods: The case control study was carried out among 154 respondents in medical oncology department, NIRCH, Dhaka from July 2016 to June 2017. Among the participants, 77 were cases who had ovarian cancer and another 77 were controls who had no ovarian cancer. Convenient sampling technique was used and data were collected by face-to-face interview using a pretested semi-structured questionnaire. Data were entered on to the template of SPSS and analysis was done.&#x0D; Results: The mean age of case and control group were 60.06±7.00 and 59.89±6.96 years respectively. Highest number of respondents were illiterate. Majority came from rural area and had no personal monthly income. Most of them were taken high fiber diet, 83.1% in case and 77.9% in control group. About 80.5% in case and 66.2% in control group had BMI ≥25 kg/m2. Sedentary workers 40.3% in case and 13.0% in control group; moderate workers were 31.2% in case and 20.8% in control group and hard workers were 28.5% and 66.2% in case and control group respectively. The mean age of menarche 12.02±1.19 years and 12.87±1.30 years in case and control group respectively and mean age of menopause in case and in control groups respectively 51.54±2.39 and 49.61±1.29 years. In case group 49.3% had early term pregnancy whereas in control group 9.5% had early term pregnancy; in case group 82.1% and in control group 86.5% had breast feeding history. Around 16.9% in case group and 27.3% in control group used to take OCP. Significantly more respondents 6.5% in case group had personal H/O breast cancer than control group. Positive family history of breast and ovarian cancer was found 16.9% in case group and 2.6% in control group. In binary logistic regression analysis for risk factors of OC was found that sedentary activity was associated with increased risk, increased BMI (≥25 kg/m2), early age of menarche (≤12 years), late age of menopause (&gt;51 years), nullipara and early term pregnancy. Family H/O breast or ovarian cancer significantly associated with development of ovarian cancer.&#x0D; Conclusion: Ovarian cancer observed more in older age group (≥60 years) among sedentary worker with high body mass index (≥25 kg/m2). Early age of menarche (≤12 years), late menopause (&gt;50 years), never having given birth to a child in life time, early term of pregnancy and family history of breast and ovarian cancer were significantly associated with ovarian cancer among post-menopausal women.&#x0D; JOPSOM 2021; 41(2):28-35

The Effect of Social Media Addiction on Premenstruel Syndrome and Sleep Quality

Objective: This study was conducted to determine the impact of social media addiction on premenstrual syndrome (PMS) and sleep quality. Material-Method: The study population consisted of female students enrolled in the Health Sciences Faculty of a public university (n=884). Data were collected using the "Personal Information Form," "Social Media Addiction Scale (SMAS)," "Premenstrual Syndrome Scale (PMSS)," and "Pittsburgh Sleep Quality Index (PSQI)" instruments. Descriptive statistics, Pearson correlation analysis and Linear Regression Analysis were used for statistical evaluation. Results: The mean age of the students was 20.40±1.65, and the mean age of menarche was 13.42±1.60. The mean total score for PMSS was 129.57±37.75, the mean total score for SMAS was 12.93±4.84, and the mean score for PSQI was 13.22±2.04. The correlation analysis revealed a positive relationship between SMAS and the total scores of PMSS and PSQI (r=.325, p=.000; r=271, p=.000). In addition, as a result of the regression analysis, a 1-unit change in the social media addiction scale score causes a positive increase of .325 units (β) on the total score of the premenstrual syndrome scale and a positive increase of 0.444 units (β) on the total score of the PSQI. Conclusion: Social media addiction was found to be an effective variable in increasing premenstrual syndrome symptoms and poor sleep quality.

Menstrual Patterns and Age of Menarche in Young Women from the United States

Background Menarche is a salient event for adolescents that marks the beginning of reproductive life and the commencement of menstrual cycles. Despite this, much less is known about how the timing of menarche is related to menstrual patterns. Methods To that end, a cross-sectional sample of 523 young women in college from the United States provided data on menarcheal age, menses and cycle length, blood loss during menses, dysmenorrhea, and menstrual cycle regularity. Sociodemographic data such as age of first sexual intercourse, presence of biological father while growing up, self-reported body weight, and urban versus rural place of residence were also obtained. Results Mean menarcheal age was 12.89±1.31-years. Regarding cycle length, 42 (8.2%) of the women had cycles shorter than 21-days, 402 (78.2%) between 21 and 35-days, and 70 (13.6%) had cycles longer than 35-days. Concerning menorrhagia, 61 (11.8%) reported a small quantity of blood loss, 363 (70.1%) a medium quantity, and 94 (18.1%) reported a large loss of blood (menorrhagia). Duration of menstrual bleeding also showed variability with 33 (6.4%), 280 (54.2%), and 204 (39.5%) reporting menstrual bleeding lasting less than 3-days, 2 to 5-days, and greater than 5-days, respectively. The overall prevalence of dysmenorrhea was 61.7% (n=319) of the sample, while 36.3% (n=187) reported irregular menstrual cycles. Logistic regression indicated that early menarche, long menses duration, large self-reported amount of blood loss, and early age of first sexual intercourse were significant predictors of dysmenorrhea, while women with small self-reported amount of blood loss, a short menses duration, and long cycles were less likely to have dysmenorrhea. Concerning the timing of menarche, participants who were over-weight, grew up in urban environments, had dysmenorrhea, had early first consensual sexual intercourse, and grew up without a biological father, were more likely to have early menarche. Conclusion These findings suggest that menstrual disorders are common among a sample of young women from the United States and also identify sociodemographic variables that are related to menarcheal age.

Determinants of menstrual hygiene among adolescent school girls in a rural area of Patna, Bihar, India: A cross-sectional study.

Adolescence is a transitional phase marked by the onset of menarche. Most adolescent girls have incomplete or inaccurate information about menstrual physiology and hygiene. There are several misconceptions and taboos linked with it, resulting in adverse health outcomes. However, numerous factors associated with menstrual hygiene are modifiable. If these are adequately identified and addressed, it can empower young girls to lead healthy life in a positive environment. (1) To assess the knowledge and practices regarding menstrual hygiene among adolescent school girls. (2) To determine the association of menstrual hygiene practices with sociodemographic and related factors. A descriptive cross-sectional study was conducted in rural Patna, Bihar, in which 300 eligible adolescent school-going menstruating girls (13-17 years) were recruited from four schools. They were interviewed using a predesigned questionnaire, and relevant information on sociodemographic profiles and menorrhoeal characteristics was obtained. Median scores were calculated for the knowledge and practices domain. Multiple logistic regression was used to determine the associated factors of menstrual hygiene practice. The mean age of girls was 14 ± 1.07 years, while the mean age of menarche was 12.37 ± 0.92 years. More than half (59.3%) were found to possess good knowledge (scores 7 and above) regarding menstruation and its physiology. Half (50.3%) of the girls had good menstrual hygiene practices (scores 9 and above). Multiple logistic regression model revealed that adolescent girls studying in government schools (AOR = 0.05, CI = 0.02-0.12) and those living in nuclear families (AOR = 0.05, CI = 0.02-0.12) were likely to be significantly associated with poor menstrual hygiene practices. Menstrual hygiene is still far from satisfactory; hence, it should be a vital aspect of the school health educational curriculum. There is an imperative need to design acceptable awareness/advocacy programs for adolescent girls in the future.
