C\u2019est l\u2019hypoth\u00e8se que Lisa-Marie Davignon, \u00e9tudiante au doctorat en psychologie \u00e0 l\u2019Universit\u00e9 du Qu\u00e9bec \u00e0 Montr\u00e9al (UQAM), a voulu explorer. Les r\u00e9sultats viennent d\u2019\u00eatre publi\u00e9s dans la revue scientifique Neuropsychopharmacology.<\/p>\n
Constats<\/p>\n
Sous la supervision de Marie-France Marin, professeure au d\u00e9partement de psychologie de l\u2019UQAM et chercheure au Centre de recherche de l\u2019Institut universitaire en sant\u00e9 mentale de Montr\u00e9al (CR-IUSMM), l\u2019\u00e9quipe de recherche a recrut\u00e9 147 participantes et participants r\u00e9partis en quatre groupes: des femmes utilisant la pilule, des anciennes utilisatrices, des femmes n\u2019y ayant jamais eu recours et des hommes.<\/p>\n
\u00c0 l\u2019aide d\u2019une imagerie par r\u00e9sonance magn\u00e9tique et de capteurs mesurant la transpiration dans la paume de la main, les chercheures ont \u00e9valu\u00e9 les r\u00e9actions de peur face \u00e0 des contextes s\u00e9curitaires et mena\u00e7ants.<\/p>\n
\u00abNos r\u00e9sultats montrent que, dans des contextes s\u00e9curitaires, les femmes qui prennent la pilule affichaient des r\u00e9actions de peur plus \u00e9lev\u00e9es que celles qui ne l\u2019avaient jamais prise, particuli\u00e8rement lorsque la pilule contenait des doses \u00e9lev\u00e9es d\u2019\u0153strog\u00e8ne synth\u00e9tique, explique Lisa-Marie Davignon, par voie de communiqu\u00e9. Les anciennes utilisatrices de pilule pr\u00e9sentaient elles aussi des r\u00e9actions accrues. Ces r\u00e9sultats nous laissent croire que certains effets de la prise de contraceptifs oraux peuvent subsister \u00e0 long terme.\u00bb<\/p>\n
Les r\u00e9sultats sugg\u00e8rent que l\u2019utilisation des contraceptifs oraux s\u2019accompagne de variations dans l\u2019activit\u00e9 de l\u2019hippocampe, une r\u00e9gion c\u00e9r\u00e9brale sensible aux hormones sexuelles et essentielle \u00e0 la m\u00e9moire contextuelle ainsi qu\u2019\u00e0 la r\u00e9gulation des \u00e9motions.<\/p>\n
Une activit\u00e9 plus importante de cette r\u00e9gion c\u00e9r\u00e9brale a \u00e9t\u00e9 observ\u00e9e chez les femmes n\u2019ayant jamais pris la pilule, ce qui pourrait expliquer leur meilleure capacit\u00e9 \u00e0 interpr\u00e9ter les contextes comme non mena\u00e7ants.<\/p>\n
\u00abNos r\u00e9sultats t\u00e9moignent de l\u2019importance de mieux comprendre l\u2019impact des hormones sur la sant\u00e9 des femmes afin de soutenir des d\u00e9cisions de contraception \u00e9clair\u00e9es, conclut la doctorante, dans la m\u00eame communication aux m\u00e9dias. Il est toutefois trop t\u00f4t pour \u00e9mettre des recommandations m\u00e9dicales \u00e0 ce sujet, puisque chaque femme est diff\u00e9rente. Si nous \u00e9veillons l\u2019int\u00e9r\u00eat de la communaut\u00e9 scientifique \u00e0 continuer d\u2019\u00e9tudier la sant\u00e9 des femmes, notre mission sera accomplie.\u00bb<\/p>\n","protected":false},"excerpt":{"rendered":"C\u2019est l\u2019hypoth\u00e8se que Lisa-Marie Davignon, \u00e9tudiante au doctorat en psychologie \u00e0 l\u2019Universit\u00e9 du Qu\u00e9bec \u00e0 Montr\u00e9al (UQAM), a…\n","protected":false},"author":2,"featured_media":32379,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[82],"tags":[17188,1487,12,13,18,17,1619,17189,17190,16585,1247,17191,10334,15926,4050,17192,17193,17194,1473,17195,4888,3814,1967,17196,17197,86,17198,12450,10454,17199,1637,4130,17200,17201,17202,17203,17204,17205,17206,17207,17208,17209,17210,1642,17211,17212,17213,17214,2543,17215,87,17216,1990,17217,1651,1652],"class_list":{"0":"post-32777","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-sante","8":"tag-acne","9":"tag-background","10":"tag-be","11":"tag-be-fr","12":"tag-belgique","13":"tag-belgium","14":"tag-birth","15":"tag-blister","16":"tag-conception","17":"tag-container","18":"tag-contraception","19":"tag-contraceptive","20":"tag-control","21":"tag-cycle","22":"tag-cycling","23":"tag-daily","24":"tag-druggist","25":"tag-drugstore","26":"tag-education","27":"tag-estrogen","28":"tag-family","29":"tag-fat","30":"tag-female","31":"tag-gynecologist","32":"tag-gynecology","33":"tag-health","34":"tag-hormonal","35":"tag-hormone","36":"tag-hospital","37":"tag-intercourse","38":"tag-medical","39":"tag-medicine","40":"tag-menstruation","41":"tag-oral","42":"tag-overweight","43":"tag-ovulation","44":"tag-packaging","45":"tag-period","46":"tag-periods","47":"tag-pharmacist","48":"tag-pharmacy","49":"tag-pill","50":"tag-planning","51":"tag-pregnancy","52":"tag-prescribe","53":"tag-prescription","54":"tag-preventative","55":"tag-progesterone","56":"tag-protection","57":"tag-rose","58":"tag-sante","59":"tag-sex","60":"tag-tablet","61":"tag-tablets","62":"tag-week","63":"tag-woman"},"share_on_mastodon":{"url":"","error":"Validation failed: Text character limit of 500 exceeded"},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/posts\/32777","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/comments?post=32777"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/posts\/32777\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/media\/32379"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/media?parent=32777"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/categories?post=32777"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/tags?post=32777"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
