The Proverbial Ticking Biological Clock: A Symbolic TMT Perspective on Mate Perception

Livick, Kendall Atkins 18 June 2014 (has links)
Past research has shown that mortality salience increases desire for offspring. Additionally, past studies have illustrated that women in a high fertility phase within a menstrual cycle show greater preference for masculine faces while performing facial judgment tasks than do women in a low fertility phase or women using hormonal contraception. However, mortality salience has been shown to influence mate selection. The current study explored whether or not a cue related to fertility salience may produce similar outcomes to cues of mortality salience observed in past studies. In partial replication of a study conducted by Vaughn, Bradley, Byrd-Craven, and Kennison (2010), the current study included 151 heterosexual female participants who self-identified as falling within cyclical high fertility or low fertility categories, or who reported using hormonal contraception. These participants were randomly assigned to either a control condition, a mortality salience condition, or a fertility salience condition and then instructed to judge images of male faces provided by Re, DeBruine, Jones, and Perrett (2013). Participants rated faces in categories of attractiveness, dominance, and health. The study predicted significant interaction effects of salience condition and fertility status on opposite sex facial perceptions. Additionally, participants were asked about procreation preferences. No effects of mortality salience or fertility salience were observed in regard to opposite sex facial perceptions, number of children desired, or preferred age for having a first child. Thus, the current research does not provide support that the fertility salience cue used in the study influences opposite sex perceptions or procreation preferences. / Master of Arts

Utilisation des substrats énergétiques à l'exercice chez la femme : influence de la contraception orale, de la prise alimentaire et de la localisation des graisses

Isacco, Laurie 07 June 2012 (has links)
La production endogène ou la prise exogène d’hormones sexuelles chez la femme génère un climat hormonal qui lui est propre. Ces particularités endocriniennes influent sur la composition corporelle et modifient les sécrétions et/ou la sensibilité de certaines hormones clés du métabolisme énergétique pouvant conduire à une utilisation spécifique des substrats énergétiques à l’exercice. L’objectif de ce travail était d’étudier l’influence d’une contraception orale (CO : mini dosée monophasique), de la prise alimentaire pré-exercice et de la localisation des graisses sur les réponses métaboliques et hormonales de la femme préménopausée et normo-pondérée à l’exercice (45 min à 65% de O2max). Nos résultats ont montré que la prise d’une CO ne modifiait pas les réponses métaboliques et hormonales et l’utilisation des substrats énergétiques à l’exercice quel que soit le statut nutritionnel des sujets (exercice à jeun ou en situation postprandiale). Cependant, à l’exercice, une situation de jeûne a favorisé une augmentation de l’oxydation lipidique et cela quel que soit le statut hormonal des sujets (CO+ ou CO-). En situation postprandiale, l’exercice physique a stimulé l’activité lipolytique chez des femmes CO+ et CO- sans distinction entre les deux groupes. Enfin, quand l’utilisation des substrats énergétiques à l’exercice est appréhendée en fonction du rapport de la masse grasse abdominale/masse grasse des membres inférieurs (A/MI), nos travaux ont montré une augmentation de la mobilisation et de l’oxydation des lipides chez les femmes présentant un plus faible rapport A/MI (malgré des masses corporelles et des tours de taille normaux). Ainsi, au sein d’une population féminine normo-pondérée, les CO minidosées monophasiques ne semblent pas influer sur l’utilisation des substrats énergétiques à l’exercice, alors que la prise alimentaire pré-exercice et la localisation des graisses semblent avoir un impact plus important sur le métabolisme énergétique à l’exercice. / In the female population, sexual hormones (endogen production or exogenous consumption) induce particular hormonal status leading to specific body composition and metabolic and hormonal responses at rest and during exercise. The aim of this work was to determine the influence of oral contraception (low dose monophasic combined OC), pre-exercise food intake and body fat mass localization on metabolic and hormonal responses during exercise (45 min at 65% of O2max) in normal weight premenopausal women. Our results showed that OC did not alter substrate mobilization and oxidation during exercise (in fast and postprandial conditions). However, during exercise performed in fast condition, women exhibited greater lipid oxidation rates whatever their hormonal status (OC+ vs OC-). In postprandial condition, exercise increased lipolytic activity in OC+ and OC- women without differences between both groups. Finally, it has been observed that abdominal to lower body (A/LB) fat mass ratio influenced substrate mobilization and oxidation in premenopausal women with normal weights and waist circumferences. Subjects with a lower ratio exhibited greater lipid mobilization and oxidation than those with a higher ratio. Therefore, in normal weight women, low dose monophasic combined OC do not appear to influence substrate oxidation whereas pre-exercise food intake and body fat mass localization may have an important impact on substrate metabolism during exercise.

Métodos: Foram avaliadas prospectivamente 140 mulheres continentes, divididas em quatro grupos de acordo com a faixa etária, G1 (n = 34) de 30 a 40 anos, G2 (n = 38) de 41 a 50 anos, G3 (n =35) de 51 a 60 anos e G4 (n= 33) acima de 60 anos. Os seguintes parâmetros foram avaliados: dados demográficos utilizando questionário clinico; hipermobilidade do colo vesical usando o teste do cotonete; trofismo vaginal com exame ginecológico; status hormonal da vagina com a colpocitologia; força muscular do AP, utilizando a perineometria e eletroneuromiografia (EMG). Resultados: Não houve diferença estatisticamente significativa entre a força muscular do AP, características demográficas, trofismo vaginal e hipermobilidade do colo vesical nos diferentes grupos (p>0,05). Foi encontrado um maior número de mulheres atróficas acima de 60 anos. Houve uma excelente concordância no trofismo vaginal avaliado pelo exame ginecológico e colpocitologia (Kappa = 0,888). Porém observamos que as mulheres com hipermobilidade apresentavam menor força muscular em relação às mulheres sem hipermobilidade na EMG. Conclusão: Apesar da atrofia vaginal ser maior nas mulheres acima de 60 anos , não observamos diferença na força muscular do AP durante o processo de envelhecimento fisiológico. Sendo assim, não podemos dizer que o trofismo é o único fator relacionado à força muscular do AP, dificultando a indicação de mulheres para profilaxia. Palavras - chave: continência urinária; força muscular; músculo assoalho pélvico; status hormonal; prolapso; hipermoblidade do colo vesical / Objectives: To assess the correlation between hormonal status and PF muscle strength. Methods: 140 continent women were prospectively evaluated, and divided into four groups according to age: G1 (n = 34) 30-40 years, G2 (n = 38) 41-50 years, G3 (n = 35) 51-60, and G4 (n = 33) older than 60 years. The following parameters were evaluated: demographic data using clinical questionnaire; hypermobility of the bladder neck using the swab test; vaginal trophism by gynecological examination; hormonal status of the vagina by cytology; muscle strength of the PF using perineometer and electromyography (EMG). Results: There was no statistical difference between PF muscle strength, demographic characteristics, vaginal trophism, and hypermobility of the bladder neck in the different groups (p > 0.05). There was a larger number of atrophic women among those over 60 years of age. Vaginal trophism assessed by physical examination was highly consistent with the findings of colpocytology (Kappa = 0.888). We found, however, that women with hypermobility by EMG had less muscle strength as compared to those with no hypermobility. Conclusion: Although vaginal atrophy is more intense in women older than 60 years, no difference was found in muscle strength of the PF during the physiological aging process. As a consequence, it is not possible to state that trophism is the only factor related to PF muscular strength, thus precluding the selection of women who should be referred to prophylaxis. Key-notes: urinary continence; muscle strength; pelvic floor muscles; hormonal status; prolapse; bladder neck hypermobility
