We don’t sit and talk about this. : Exploring menarche and menstrual experiences of Primary Teachers in Catalonia and Sweden

Saladrigas Clemente, Marina January 2023 (has links)
We don’t sit and talk about this, aims at quite the opposite. While societies such as the Catalan and Swedish have become more gender equal and seem to advance towards being more welcoming for menstruating bodies, there are still many discomforts and oppressions related to the menstrual experience. The research in this subject has been primarily focused on menstrual health and hygiene management issues, while ignoring the social and cultural aspects related to this natural bodily process. Indeed, the menstrual cycle is a biological and psychological journey, throughout women lifespan. Acknowledging the complexity and uniqueness of the menstrual experience, this study aims at exploring and comparing the menarche and menstruation experiences of Primary school teachers. Aiming at examining two specific settings, this research sampled National and International teachers, specifically 9 teachers working and living in Catalonia and 9 teachers working and living in Sweden. Drawing from these two samples, in-depth interviews were conducted, and the resulting findings were analyzed through thematic analysis. The diverse sample of this investigation shows differences and similarities among the two settings, mainly referring to their current embodied experience of menstruation and their way of approaching menstrual-related issues within the school context. It appears, then, that the women that participated in this study faced menarche without the adequate support and information. Besides, menarche was the period where they learnt and interiorized the social and cultural norms of hiding and concealing menstruation and faced physical restrictions. As they grew older, some of these women changed their way of managing and communicating about their period. However, the topic was still difficult to share and discuss, not only in their private life but in their role as teachers, where they attempt to promote a period positive image and help their daughters and students have a comforting menstrual experience. The findings are further discussed considering the concepts of menstrual etiquette, institutional non-acceptance,and the pollution theory and the development theory of embodiment.

Vybrané auxologické aspekty menarche / Selected auxological aspects of menarche

Švecová, Martina January 2013 (has links)
Thesis aims to analyze some auxological aspects of menarche in a sample of peripubertal school-aged Prague girls. Sample PRAHA 2012 consists of 293 girls from Prague within the age ranging from 11,00 - 14,99 years. Ascertained median age of menarche 12,4 years is significantly lower (p = 0,0004) than median of Prague population - 13,04 years, respectively lower than median age of menarche of Czech population - 13,00 years according to data from the last national anthropological survey (CAV 2001). Our investigation suggests a "break off" in long-term stagnation age of menarche (minus 0,6 year) at least in a urban population in Czech Republic. According to our findings deceleration age of menarche wasn't accompanied by increase of average body height or other nutritional characteristics (body weight, BMI, arm circumference, thickness of skinfolds) in comparison with actual pediatrics standards. Though, there is a clearly evidence that participant's body composition affected age of menarche. A comparison of premenarcheal (n = 139) and postmenarcheal (n = 154) girls of the same age showed statistically significant elevated values in body weight (42,5 kg, 47,6 kg vs 56,3 kg, 54,1 kg), BMI (17,6 kg/mš, 18,3kg/mš vs 21,3 kg/mš, 20,7 kg/mš) and percentage of body fat (19,4%, 19,7% vs 24,5% a 23,1%) at...

LEITE, F. Influência da restrição de crescimento intra-uterino na idade da menarca: estudo da coorte de nascidos vivos de Ribeirão Preto de 1978/9. 2008. 85 p. Dissertação (Mestrado) apresentada à Faculdade de Medicina de Ribeirão Preto/USP. A idade da menarca é um marco da puberdade e, quando antecipada, parece estar associada a um maior risco de desenvolvimento de câncer de mama, síndrome metabólica e obesidade. É possível que alterações no ambiente intrauterino, como a restrição de crescimento do feto, levem a interferências no sistema hipotálamo-hipófise-gonadal resultando em alterações na idade da menarca. Em vista da controvérsia dos fatores que influenciam na idade da menarca, este estudo testou a hipótese da associação entre restrição de crescimento intra-uterino (baixo peso ao nascer, pequeno para idade gestacional, restrição intra-uterina de Kramer) e antecipação da idade da menarca. Em uma sub-amostra foi testada a possível interação entre a restrição de crescimento intra-uterino e o índice de massa corpórea. Para esse estudo foram utilizadas informações coletadas nos seguimentos de 1987/9 e 2004/5 de 1056 meninas nascidas em Ribeirão Preto, provenientes do estudo de coorte dos nascidos vivos em Ribeirão Preto de 1978/9. Menarca antecipada foi definida como primeiro sangramento vaginal ocorrido antes dos 12 anos de idade. Análise univariada foi seguida de análise bivariada e multivariada por meio de modelo generalizado empregando distribuição de Poisson para estimativa de riscos relativos e erro padrão por meio de método robusto. Os fatores de confusão controlados foram idade, escolaridade e situação conjugal da mãe, número de irmãos, comprimento ao nascer, prematuridade e índice de massa corpórea (apenas para a subamostra). Em média, a menarca ocorreu aos 12,3 anos (DP=1,5). A ocorrência de menarca antecipada foi de 27,7% (n= 293) para a coorte inteira e de 29,1% (n= 172) na sub-amostra. Foi encontrada associação negativa entre restrição de crescimento intra-uterino, seja representado por baixo peso ao nascer (Risco Relativo, RR= 0,47; Intervalo de Confiança de 95%, IC95%: 0,26-0,84), pequeno para idade gestacional (RR = 0,57;IC95%:0,37-0,89) ou restrição de Kramer (RR= 0,65; IC95%:0,47-0,92), com a antecipação da idade da menarca. Os resultados foram semelhantes na análise da sub-amostra, porém sem significância estatística. Quando o índice de massa corpórea foi considerado na análise da sub-amostra, não houve modificação dos resultados. Desta forma, este estudo demonstrou associação negativa entre restrição de crescimento intra-uterino e antecipação da idade da menarca, ou seja, a restrição de crescimento foi fator de proteção da menarca antecipada. / LEITE, F. Influence of intrauterine growth restriction on the age of menarche: the cohort study of live births of Ribeirao Preto in 1978/9. 2008. 85 p. Dissertation (Master) submitted to the Faculty of Medicine of Ribeirao Preto/USP. This study tested the hypothesis of association between intrauterine growth restriction and early age of menarche. For this study, follow-up data (n = 1056) from the population based livebirth cohort study of Ribeirao Preto of 19789 were analyzed. Early menarche was defined as having the first menstrual event before 12 years-old and intrauterine growth restriction was defined by three measurements: low birthweight (< 2500grs), small for gestational age (< 10% Williams growth curve) and fetal growth ratio (< 0.85 mean weight for gestational age). Relative risks were estimated by generalized estimation equations (Poisson distribution) with robust method for estimation of standard errors. Analyzes were adjusted for maternal age, education and marital status, number of siblings, birth length and preterm. Body mass index was tested as intervenient or interaction factor in a subsample of the cohort examined at 9 yrs-old. The mean age of menarche was 12.3 years (Standard Deviation = 1.5). Early menarche was observed for 27.7% for the entire cohort and 29.1% for the sub-sample. Negative association was observed between intrauterine growth restriction and early menarche. The adjusted relative risks and respective confidence intervals (95% CI) for low birth weight, small for gestational age and fetal growth ratio were respectively: 0.47 (95% CI: 0.26-0.84), 0.57 (95% CI: 0,37-0,89), and 0.65 (95%CI: 0,47-0, 92). No evidence that body mass index was an intermediate or interaction factor was observed. Thus, this study showed a negative association between intrauterine growth restriction and anticipation of age of menarche.

Idade da menopausa em mulheres idosas do município de São Paulo: fatores associados e análise de sobrevida / Age at menopause among elderly women in the São Paulo municipality: associated factors and survival analysis

Román Lay, Alejandra Andrea 15 October 2018 (has links)
Introdução: O crescimento do número de idosos no Brasil tem aumentado o interesse em identificar os determinantes da sua sobrevida e da incidência de doenças crônicas. A menopausa é definida como a cessação permanente da menstruação e está associada à diminuição da secreção de estrógenos por perda da função folicular, marcando o fim da fase reprodutiva na vida feminina. A idade da menopausa tem sido associada em alguns estudos internacionais com a mortalidade e algumas causas de morbidade, mas faltam estudos sobre o tema no Brasil. Esta tese será apresentada por meio de 3 artigos. O primeiro analisou os fatores associados à idade da menopausa natural em mulheres do estudo SABE (Saúde, Bem-estar e Envelhecimento). O tabagismo e a escolaridade estiveram estatisticamente associados com uma menopausa mais cedo nas três coortes analisadas: 2000, 2006 e 2010. Mulheres fumantes atuais tiveram 35% maior risco de ter menopausa precoce (HR=1.35, 95% CI: 1.12, 1.62) e as ex-fumantes 27% maior risco (HR=1.27, 95% CI: 1.09, 1.50), em comparação com as mulheres que nunca fumaram. Em relação à escolaridade, as mulheres com 8 anos ou mais de estudos tiveram 33% menor risco de menopausa precoce (HR=0.67, 95% CI: 0.50, 0.89) comparadas às mulheres sem escolaridade. Estado civil e número de filhos estiveram associados a uma menopausa mais tardia na coorte 2006. No segundo artigo, foi realizada uma análise de sobrevida segundo a idade da menopausa natural das mulheres pertencentes à coorte 2000. Foram identificados 444 óbitos de mulheres até 2016. Mulheres com menopausa precoce tiveram 48% de maior risco de mortalidade geral (HR=1.48, 95% IC: 1.03, 2.14) comparadas às mulheres com idade de menopausa entre os 50 e 54 anos (referência). Em relação à mortalidade específica, mulheres entre 41 e 49 anos apresentaram o dobro de risco de mortalidade por neoplasias em comparação com o grupo de referência. No terceiro artigo, foi realizada uma revisão sistemática e meta-análise dos fatores reprodutivos associados à menopausa natural. Os três fatores estudados apresentaram uma associação com a menopausa tardia. As mulheres com uso de anticoncepcionais orais em relação àquelas que não relataram uso de anticoncepcionais orais (HR=0.86, CI=0.79, 0.92), as com idade da menarca >=13 anos comparadas àquelas com idade da menarca <13 anos (HR=0.88, CI=0.84, 0.93) e aquelas que relataram ter um filho ou mais comparadas com as que não tiveram filhos (HR=0.80, CI=0.76, 0.85). / Introduction: The increase of the elderly population in Brazil has raised concerns about their care and the determinants of survival and incidence of chronic diseases. Menopause is defined as the permanent end of a woman\'s menstruation and is associated with the decline of the release of estrogens due to loss of follicular function, indicating the end of the reproductive phase of a woman\'s life. Age at menopause has been linked with mortality and morbidity in international studies. The first article of this thesis analyzed the factors associated with age at natural menopause among women of the SABE study cohort (Health, Well-Being, Aging). Smoking and education were associated with earlier menopause for the three waves analyzed: 2000, 2006 and 2010. Current smokers had 35% higher risk of earlier natural menopause (HR=1.35, 95% CI: 1.12, 1.62) and former smokers had 27% higher risk of earlier natural menopause (HR=1.27, 95% CI: 1.09, 1.50), in comparison with never smokers. Regarding education, women with 8 years or more of formal education had 33% lower risk of earlier natural menopause (HR=0.67, 95% CI: 0.50, 0.89) than women with no education. Marital status and parity were associated with later age at natural menopause only in 2006. In the second article, a survival analysis was performed according to age at natural menopause in women from SABE 2000. We found a total of 444 deaths from 2000 to 2016. Women with earlier menopause had 48% increased risk of all-cause mortality (HR=1.48, 95% IC: 1.03, 2.14) compared to women with age at menopause between 50 and 54 years (reference group). Regarding cause-specific mortality, women with ages at natural menopause between 41 and 49 had twice the risk of cancer mortality compared to the reference group. In the third article, we performed a systematic review and meta-analysis of the reproductive factors associated with natural menopause. The three factors analyzed were statistically associated with later menopause: women with use of oral contraceptives before menopause compared to women with no use of oral contraceptive (HR=0.86, CI=0.79, 0.92), women with age at menarche >=13 compared to women with age at menarche <13 years (HR=0.88, CI=0.84, 0.93) and those with one or more live births compared to nulliparous women (HR=0.80, CI=0.76, 0.85).

The Role of Menstruation : a Case Study amongst Women from Nakwa Village in Tanzania / Menstruationens roll : En fallstudie bland kvinnor från Nakwa Village i Tanzania

Danielsson, Anna January 2017 (has links)
This study investigates what role menstruation have for women in the village of Nakwa, Tanzania; how inadequate MHM affects the perception of women; and how menstruation is affecting the gender equality within a marriage in Nakwa. Most women in Nakwa village struggle to maintain high standards of cleanliness regarding their own Menstrual Hygiene Management (MHM). This is due to many contributing factors relating to ingrained cultural beliefs that menstruation is something shameful and dirty. Most males within the household manage the finances, and menstrual hygiene products are not considered a priority, which further detaches the women from the possession of power over their own MHM. The theoretical framework used in this study is built upon two pillars, the woman as the inferior sex, and menstruation as something dirty and polluting, contributing to menstrual shame. These pillars are constructed upon two academic works; The Second Sex (1953) by Simone De Beauvoir, and Purity and Danger (1984) by Mary Douglas. Substantive previous research is accounted for to support the two pillars. Two weeks of field studies in Nakwa village during February and March 2017 included 23 individual semi-structured interviews and one group interview, with regularly menstruating married women. The results show a linkage between inadequate MHM, devaluation and inferiority of women and gender inequality.

Edad de menarquia y su asociación con el Índice de Masa Corporal en estudiantes universitarias, Lima, 2018

Urteaga Flores, Anthony Andre, Robles Heredia, Miluska Daniela 28 October 2020 (has links)
Introducción/objetivos: Estudios previos reportaron asociaciones inconsistentes entre la edad de la menarquia y el Índice de masa Corporal (IMC). El objetivo del presente estudio fue examinar esta relación entre estudiantes universitarias. Materiales y métodos: Las participantes incluidas fueron 309 mujeres entre 18 y 30 años de una universidad privada en la ciudad de Lima, Perú durante 2018 - 2019. Estudio observacional transversal analítico donde la edad de menarquia se obtuvo por auto reporte y el IMC fue medido por los evaluadores. Se utilizó un análisis de regresión lineal múltiple para evaluar la asociación entre la edad de menarquia y el IMC ajustado por sus posibles confusores. Resultados: La media de edad de menarquia fue de 12.0 ± 1.4. Se encontró sobrepeso y obesidad en el 26.8% y 5.50% de las participantes respectivamente. No se encontró correlación significativa entre la edad de menarquia y el IMC. (Rho= -0.08; 95% Intervalo de confianza [IC] -0.19 a 0.03; p=0.165) En el modelo ajustado por la edad, actividad física y consumo de frutas y verduras a la que pertenecía la participante, la edad de menarquia estuvo inversamente asociada al IMC de forma significativa. (coeficiente β: -0.29, IC 95% -0.57 a 0.01; p=0.042) Conclusiones: Una edad de menarquia menor estuvo asociada significativamente con un mayor IMC en estudiantes universitarias. / Introduction/objectives: Previous studies reported inconsistent associations between age at menarche and Body Mass Index (BMI). The aim of the present was to examine this relationship among college students. Materials and methods: The participants included 309 women between 18 to 30 years old from a private university in Lima, Peru, from 2018 to 2019. Observational transversal analytic study where the age at menarche was obtained by self-reports and the BMI was measured by the researchers. A multiple linear regression analysis was used to assess the association between age at menarche and BMI adjusted for its possible confounders. Results: The mean age at menarche was 12 ± 1.4. Overweight and obesity were found among 26.8% and 5.5% of the participants, respectively. No significant correlation was found between the age at menarche and the BMI. (Rho= -0.08; 95% confidence interval [CI] -0.19 to 0.03; p=0.165) In the adjusted model by age, physical activity and fruit and vegetable consumption, the age at menarche was inversely associated with the BMI in a significant manner. (coefficient β: -0.29, IC 95% -0.57 to 0.01; p=0.042) Conclusions: Earlier menarche was significantly associated with a greater BMI in college students. / Tesis
