Menstrual dysfunction and body weight dissatisfaction among Finnish young athletes and non-athletes.
2020
To determine the prevalence of menstrual dysfunction (MD; i.e. oligomenorrhea or amenorrhea) and attitudes towards body weight among athletes and non‐athletes, we studied a cohort of athletes and non‐athletes, in adolescence (14–16 years) and subsequently in young adulthood (18–20 years). We further studied the differences between athletes reporting MD and eumenorrheic athletes at both time periods and identified physical and behavioural characteristicsthat might predict MD in young adulthood. Data were collected using questionnaires, accelerometers, and a pre‐participation screening. In adolescence, the athletes reported current primary amenorrhea more often than the non‐athletes (4.7% vs.…
Associations of Sex Hormones and Hormonal Status With Arterial Stiffness in a Female Sample From Reproductive Years to Menopause
2021
Objective: Loss of sex hormones has been suggested to underlie menopause-associated increment in cardiovascular risk. We investigated associations of sex hormones with arterial stiffness in 19–58-years-old women. We also studied associations of specific hormonal stages, including natural menstrual cycle, cycle with combined oral contraceptives (COC) and menopausal status with or without hormone therapy (HT), with arterial stiffness. Methods: This study includes repeated measurements of 65 healthy women representing reproductive (n=16 natural, n=10 COC-users) and menopause (n=5 perimenopausal, n=26 postmenopausal, n=8 HT-users) stages. Arterial stiffness outcomes were aortic pulse wave veloc…
Self-Reported Restrictive Eating, Eating Disorders, Menstrual Dysfunction, and Injuries in Athletes Competing at Different Levels and Sports
2021
The purpose of this study was to investigate the prevalence of self-reported restrictive eating, current or past eating disorder, and menstrual dysfunction and their relationships with injuries. Furthermore, we aimed to compare these prevalences and associations between younger (aged 15–24) and older (aged 25–45) athletes, between elite and non-elite athletes, and between athletes competing in lean and non-lean sports. Data were collected using a web-based questionnaire. Participants were 846 female athletes representing 67 different sports. Results showed that 25%, 18%, and 32% of the athletes reported restrictive eating, eating disorders, and menstrual dysfunction, respectively. Higher ra…
Vaginadialogeja : kuukautisveren tabu Hanni Haapaniemen Neitsyt Maria -maalauksissa
2015
Tässä pro gradu -tutkielmassa käsitellään kuukautisveren symboliikkaa taiteessa. Tutkimuskohteina ovat Hanni Haapaniemen kolme kuukautisverellä maalattua Neitsyt Maria -aiheista teosta. Tutkimuskysymys voiko lika rikkoa pyhän idean? johdattaa selvittämään pyhän käsitteen muodostumista sekä kansanuskon että kristinuskon konteksteissa, sillä yhteisöt ovat jo ennen kirkkouskontojen syntymistä erottaneet pyhää määrittäneet kohteensa profaanista erilaisin tabusäännöin määritellyin rajanvedoin. Kuukautisveren symboliikka on kahtiajakoinen, sillä se pyhän veren metaforana yhdistyy ruumiineritteeseen, joka ylittää ihmisruumiin symboliset ja fyysiset rajat ”tunkeutuen” ulos pyhän, eheän ruumiin yhte…
Predicting the age at natural menopause in middle-aged women
2021
Objective To predict the age at natural menopause (ANM). Methods Cox models with time-dependent covariates were utilized for ANM prediction using longitudinal data from 47 to 55-year-old women (n = 279) participating in the Estrogenic Regulation of Muscle Apoptosis study. The ANM was assessed retrospectively for 105 women using bleeding diaries. The predictors were chosen from the set of 32 covariates by using the lasso regression (model 1). Another easy-to-access model (model 2) was created by using a subset of 16 self-reported covariates. The predictive performance was quantified with c-indices and by studying the means and standard deviations of absolute errors (MAE ± SD) between the pre…
Influence of Menstrual Cycle or Hormonal Contraceptive Phase on Energy Intake and Metabolic Hormones—A Pilot Study
2021
Sex hormones are suggested to influence energy intake (EI) and metabolic hormones. This study investigated the influence of menstrual cycle (MC) and hormonal contraceptive (HC) cycle phases on EI, energy availability (EA), and metabolic hormones in recreational athletes (eumenorrheic, NHC = 15 and monophasic HC-users, CHC = 9). In addition, 72-h dietary and training logs were collected in addition to blood samples, which were analyzed for 17β-estradiol (E2), progesterone (P4), leptin, total ghrelin, insulin, and tri-iodothyronine (T3). Measurements were completed at four time-points (phases): Bleeding, mid-follicular (FP)/active 1, ovulation (OVU)/active 2, mid-luteal (LP)/inactive in NHC/C…
Dietary Intake, Serum Hormone Concentrations, Amenorrhea and Bone Mineral Density of Physique Athletes and Active Gym Enthusiasts
2023
As the diet, hormones, amenorrhea, and bone mineral density (BMD) of physique athletes (PA) and gym enthusiasts (GE) are little-explored, we studied those in 69 females (50 PA, 19 GE) and 20 males (11 PA, 9 GE). Energy availability (EA, kcal·kgFFM−1·d−1 in DXA) in female and male PA was ~41.3 and ~37.2, and in GE ~39.4 and ~35.3, respectively. Low EA (LEA) was found in 10% and 26% of female PA and GE, respectively, and in 11% of male GE. In PA, daily protein intake (g/kg body mass) was ~2.9–3.0, whereas carbohydrate and fat intakes were ~3.6–4.3 and ~0.8–1.0, respectively. PA had higher protein and carbohydrate and lower fat intakes than GE (p <…
Adolescent Sport Participation and Age at Menarche in Relation to Midlife Body Composition, Bone Mineral Density, Fitness, and Physical Activity
2020
This study aimed to investigate the associations of competitive sport participation in adolescence and age at menarche (AAM) with body composition, femoral neck bone mineral density (BMD), physical performance, and physical activity (PA) in middle-aged women. 1098 women aged 47&ndash
Eating behaviours, menstrual history and the athletic career: a retrospective survey from adolescence to adulthood in female endurance athletes
2023
AimTo evaluate differences in menstrual and pubertal history and trends in eating behaviours among women with and without a competitive sports background. Additionally, we investigated if menstrual history and eating behaviours are associated with sports career-related factors.MethodsThis retrospective study was conducted on 100 women with a competitive endurance sports background and their age-matched, gender-matched and municipality-matched controls (n=98). Data were collected using a questionnaire using previously validated instruments. Generalised estimating equations were used to calculate associations of menstrual history and eating behaviours with outcome variables (career length, pa…
Alapään tiivisteen vuodosta öljynvaihtoviikkoihin : kuukautistabun vaikutus kuukautisasenteisiin ja -kiertoilmauksiin
2018
Tämän tutkielman aiheena on kuukautistabun näkyminen kiertoilmauksien käytössä, affektisuudessa sekä puhumiseen liittyvissä asenteissa. Tutkielma pyrkii selvittämään kuukautistabun olemassaoloa kyselytutkimuksella. Aineistona tutkielmassa toimii 787 kyselylomaketta, joiden analyysissä hyödynnettiin monimuotoisesti kvantitatiivisen analyysin eri keinoja, kuten luokittelua sekä vertailua. Kyselyssä vastaajat saivat arvioida omaa asennettaan kuukautisista puhumiseen sekä määrittää kiertoilmausvaihtoehdoista ne, joita käyttävät. Tämän lisäksi tutkielmassa selvitetään kiertoilmausten käytön syitä sekä ilmauksien affektisuutta. Tutkielma lähestyy aihetta neljän tutkimuskysymyksen avulla: 1. Mitä …
