“…Based on the study outcomes, future interventions would consider targeting elementary-school girls through the school health system. Developing interventions that target elementary-school girls is logical because menstrual pain tends to occur after menarche [ 6 ], the age at menarche is becoming lower [ 36 , 37 ], eating habits are becoming more convenience-oriented, and elementary-school girls are at a stage where they form habits in their daily life [ 38 ]. Therefore, it is critical for girls to form healthy dietary habits to protect themselves from exposure to EDCs starting at an early age.…”

Background Exposure to endocrine-disrupting chemicals (EDCs) occurs mainly through dietary intake. Due to current lifestyle trends, young people tend to consume fast food, to use disposable products, and to utilize convenient household items, all of which are major sources of EDCs. This study aimed to investigate the effects of a dietary modification intervention on menstrual pain and urinary bisphenol A (BPA) levels throughout three menstrual cycles in female college students who experienced severe menstrual pain. We also analyzed participants’ adherence to the intervention and examined whether their level of adherence was associated with differences in the effects of the intervention. Methods A single-group pretest and repeated posttest experimental design was employed. Thirty female college students with a score of 5 or higher on a menstrual pain scale were recruited through convenience sampling. During three menstrual cycles, menstrual pain was scored on a 10-point scale after each cycle, and urinary BPA levels were measured from the first morning urine collected after each cycle. The intervention involved three components: small-group education, follow-up monitoring, and peer support via social network communication. Statistical analyses were conducted using Friedman one-way repeated-measure analysis of variance by ranks, non-parametric two-way analysis of variance, and the Wilcoxon signed-rank test as a post-hoc test. Results The dietary modification intervention had significant effects on menstrual pain at all three time points of menstrual cycles (χ2 = 119.64, p = 0.000) and on urinary BPA levels until the 2nd menstrual cycle (χ2 = 205.42, p = 0.000). Slightly fewer than half (43.3%) of the participants were highly adherent. Menstrual pain differed according to adherence level (F = 4.67, p = 0.032) and decreased over time through the third cycle post-intervention (F = 18.30, p = 0.000). Urinary BPA levels also decreased significantly (F = 7.94, p = 0.000), but did not differ according to adherence level. Conclusions The dietary modification intervention was effective and sustainable for reducing menstrual pain and urinary BPA levels. Detailed information about EDCs and dietary experiences seemed to encourage the young women to become more concerned about EDCs and to perform self-protective actions. Further experimental research is suggested to examine the relationships of EDCs with various health indicators in women. Trial registration: KCT0005472 at 2020-9-24 retrospectively registered.

“…In Indonesia, menarcheal age is 13 years [6]. Carnelo et al, in a systematic review, reported age at menarche in a USA population to be 12 years [7]. In Nigeria, the average age at menarche varies from one geopolitical zone to another [8]- [13].…”

Background: Menarche is an important indicator of pubertal development in adolescent girl. Age at menarche has declined over the years attributable to many factors. Objective: To determine the age at menarche of secondary school adolescent girls and its relationship with anthropometric values, nutritional status, social class of parents, and category of school. Subjects and Methods: Cross-sectional study of 311 secondary school adolescent girls (10 -19 years) from two secondary schools (boarding school-Maria Regina secondary school Nnewi and Anglican Girls Secondary School Nnewi-day school) in Nnewi North LGA of Anambra State, Southeastern Nigeria, between May and June 2018. Semi-structured questionnaires were used to extract their data on sociodemographic characteristics and age at menarche. Height and weight were measured using WHO recommended methods. Body mass index (BMI) was determined using the Quetelet index (kg/m 2 ). The relationship between menarche and anthropometric measurement was determined. Results: Of the 313 participants, 212 (68.2%) were post menarcheal, while 99 (31.8%) were pre-menarcheal. The mean age at menarche was 12.79 ± 1.20 years. Early menarcheal age was associated with significantly higher anthropometric values and BMI. Boarding-students had significantly lower menarcheal age (12.69 ± 1.26) compared to the day students (12.86 ± 1.15); students with parents of the high social class had lower menarcheal age (12.56 ± 1.51), compared to those with parents of low social class (12.90 ± 1.05). Conclusion: There was a significant relationship between age at menarche and the nutritional status of the participants. Students with parents of high social class and those in boarding houses had a relatively lower age at menarche. Adequate attention should be given to the nutrition of premenarcheal school girls and those of parents with low social class. Boarding school authorities should ensure measures to alleviate stress amongst boarding-school students.

“…The results based on such a small group of patients did not reveal any significant gynecological dysfunction. The median age of menarche seems to be higher than current global average which is 12 years, but we need to notice that this age is declining in recent years [23].…”

Introduction. Lung cancer remains the most frequent cause of death related to cancers, reaching 1.8 mln worldwide. We observe globally that the incidence of lung cancer in the never smokers affects women disproportionately more often than men.Material and methods. The aim of the study was to analyse the data about women suffering from lung cancer, with particular emphasis on their gynecological and obstetrical history. Women with confirmed primary lung cancer were evaluated (n = 29). Information about smoking, gynecological and obstetrical history was obtained from a self-administered questionnaire. Demographic data were also collected.Results. The most frequent lung cancer was adenocarcinoma (51.7%), followed by squamous-cell carcinoma (31.0%) and small-cell lung cancer (17.2%). Epidermal growth factor receptor (EGFR) mutations were present in 3 cases. The vast majority of women were smokers (89.7%) with median 30 pack years (IQR 20-48). Evaluating the TNM classification, the highest number of patients was classified to stage III (44.8%).The median age of menarche was 14 years, menopause -50 years, the number of days with bleeding in the menstrual cycle -4 and the length of the menstrual cycle -28 days. An overwhelming majority of women have given birth to a child. Women reported extended menstrual cycles as the most frequent menstrual disorder (6 cases, 20.7%). Hormone replacement therapy and intrauterine contraceptive device use were declared in 10.3%. Conclusions.The results based on the small group of patients did not reveal any significant gynecological dysfunctions in our sample group with lung cancer.
