Noi cercet\u0103ri realizate sugereaz\u0103 c\u0103 aceste temeri ar putea fi asociate cu o \u00eemb\u0103tr\u00e2nire mai rapid\u0103 la nivel celular \u00een r\u00e2ndul femeilor.<\/p>\n

\u201eAnxietatea legat\u0103 de \u00eemb\u0103tr\u00e2nire nu este doar o preocupare psihologic\u0103, ci poate l\u0103sa urme \u00een corp, cu consecin\u021be reale asupra s\u0103n\u0103t\u0103\u021bii\u201d.<\/p>\n

Mul\u021bi adul\u021bi se confrunt\u0103 cu \u00eengrijor\u0103ri legate de \u00eemb\u0103tr\u00e2nire, inclusiv temeri privind boala, declinul fizic \u0219i pierderea independen\u021bei. Cercet\u0103ri anterioare au ar\u0103tat c\u0103 stresul psihologic persistent poate influen\u021ba \u00eemb\u0103tr\u00e2nirea biologic\u0103 prin modific\u0103ri epigenetice, adic\u0103 schimb\u0103ri \u00een modul \u00een care genele sunt activate sau dezactivate.<\/p>\n

\u201e\u0218tim din cercet\u0103ri anterioare c\u0103 anxietatea, depresia \u0219i s\u0103n\u0103tatea mintal\u0103, \u00een general, sunt asociate cu numeroase rezultate privind s\u0103n\u0103tatea fizic\u0103, dar p\u00e2n\u0103 acum cercet\u0103torii nu s-au concentrat asupra faptului dac\u0103 exist\u0103 o corela\u021bie \u00eentre \u00eengrijorarea fa\u021b\u0103 de \u00eemb\u0103tr\u00e2nire \u0219i procesul de \u00eemb\u0103tr\u00e2nire \u00een sine\u201d, a explicat Rodrigues.<\/p>\n

Femeile pot fi deosebit de vulnerabile la anxietatea legat\u0103 de \u00eemb\u0103tr\u00e2nire. A\u0219tept\u0103rile sociale privind tinere\u021bea \u0219i aspectul fizic, precum \u0219i preocup\u0103rile legate de fertilitate, pot amplifica stresul la v\u00e2rsta mijlocie.<\/p>\n

\u201eFemeile aflate la mijlocul vie\u021bii pot avea multiple roluri, inclusiv \u00eengrijirea p\u0103rin\u021bilor \u00een v\u00e2rst\u0103. Pe m\u0103sur\u0103 ce \u00ee\u0219i v\u0103d membrii mai \u00een v\u00e2rst\u0103 ai familiei \u00eemb\u0103tr\u00e2nind \u0219i \u00eemboln\u0103vindu-se, pot \u00eencepe s\u0103 se team\u0103 c\u0103 li se va \u00eent\u00e2mpla \u0219i lor acela\u0219i lucru\u201d, a explicat Rodrigues.<\/p>\n

Detaliile studiului<\/h2>\n

Pentru a analiza leg\u0103tura dintre anxietatea legat\u0103 de \u00eemb\u0103tr\u00e2nire \u0219i \u00eemb\u0103tr\u00e2nirea biologic\u0103, cercet\u0103torii au examinat datele a 726 de femei participante la studiul Midlife in the United States (MIDUS).<\/p>\n

Participantele au raportat \u00een ce m\u0103sur\u0103 se tem c\u0103 vor deveni mai pu\u021bin atractive, c\u0103 vor dezvolta probleme de s\u0103n\u0103tate sau c\u0103 vor fi prea \u00een v\u00e2rst\u0103 pentru a avea copii.<\/p>\n

Au fost analizate \u0219i probe de s\u00e2nge, folosind dou\u0103 \u201eceasuri\u201d epigenetice consacrate. Unul a m\u0103surat viteza \u00eemb\u0103tr\u00e2nirii biologice (DunedinPACE), iar cel\u0103lalt a estimat deteriorarea biologic\u0103 acumulat\u0103 \u00een timp (GrimAge2).<\/p>\n

Femeile care au raportat niveluri mai ridicate de anxietate legat\u0103 de \u00eemb\u0103tr\u00e2nire au prezentat semne de \u00eemb\u0103tr\u00e2nire accelerat\u0103, conform ceasului DunedinPACE.<\/p>\n

Cercet\u0103ri anterioare au asociat aceast\u0103 accelerare cu declin fizic \u0219i cu un risc mai mare de boli legate de v\u00e2rst\u0103.<\/p>\n

Nu toate tipurile de \u00eengrijor\u0103ri au avut acela\u0219i impact.<\/p>\n

Temerile legate de deteriorarea s\u0103n\u0103t\u0103\u021bii au fost cel mai puternic asociate cu \u00eemb\u0103tr\u00e2nirea biologic\u0103 accelerat\u0103. \u00cen schimb, preocup\u0103rile privind aspectul fizic \u0219i fertilitatea nu au fost asociate semnificativ cu \u00eemb\u0103tr\u00e2nirea epigenetic\u0103.<\/p>\n

Cercet\u0103torii noteaz\u0103 c\u0103 \u00eengrijor\u0103rile legate de s\u0103n\u0103tate pot fi mai persistente \u00een timp, \u00een timp ce cele privind frumuse\u021bea \u0219i reproducerea pot sc\u0103dea odat\u0103 cu \u00eenaintarea \u00een v\u00e2rst\u0103.<\/p>\n

S\u0103n\u0103tatea mintal\u0103 \u0219i s\u0103n\u0103tatea fizic\u0103 sunt str\u00e2ns legate<\/h3>\n

Rezultatele subliniaz\u0103 c\u00e2t de str\u00e2ns legate sunt s\u0103n\u0103tatea mintal\u0103 \u0219i cea fizic\u0103 de-a lungul vie\u021bii, chiar dac\u0103 adesea sunt tratate separat.<\/p>\n

\u201eCercetarea noastr\u0103 identific\u0103 anxietatea legat\u0103 de \u00eemb\u0103tr\u00e2nire drept un determinant psihologic m\u0103surabil \u0219i modificabil, care pare s\u0103 influen\u021beze biologia \u00eemb\u0103tr\u00e2nirii\u201d, a declarat un profesor asociat de \u0219tiin\u021be sociale \u0219i comportamentale \u0219i autorul senior al studiului.<\/p>\n
