Hensikt: Hensikten med studien er å fordype kunnskapen om hvordan gravide kvinner opplever en tidlig ultralydundersøkelse med risikovurdering for kromosomavvik, og hvordan de resonnerer omkring resultatet. Nytteverdien blir å løfte frem denne kunnskapen, og ta den med i den videre debatten omkring dette tema. Metode: Det ble gjort en kvalitativ intervjuundersøkelse med ti gravide kvinner som skulle få utført en risikovurdering for kromosomavvik. Kvinnene ble intervjuet både før og etter undersøkelsen. Grounded theory ble benyttet som analysemetode. Resultater: I studien ble det ble generert en kjernekategori; Jeg vil ha valget, men ikke ta det, og fem hovedkategorier: Eksistensielle valg, Trygghetsfølelse, Engstelse, Skyldfølelse og Veiledning / Ivaretakelse. Kjernekategorien beskriver kvinnenes konflikt mellom å ville ha muligheten til denne undersøkelsen, og samtidig ha vanskeligheter med å ta de påfølgende valgene. Noen av faktorene som gjorde valgene så vanskelige var engstelse, tap av kontroll / mestring, tilknytning til fosteret, skyldfølelse og sosialt press. Siden kvinnene ønsket selvstendige valg uten påvirkning fra andre, følte de også en større ansvarlighet for de valg som ble tatt. Forståelsen av den kalkulerte risikoen varierte mellom kvinnene, og de benyttet ulike metoder for å lette vurderingen og valget. Gravide kvinner har et stort informasjonsbehov når det gjelder prenatal diagnostikk, og de ønsker en lett tilgjengelighet til spesialisthelsetjenesten. For å få tid til refleksjon over egne verdier og holdninger, er det viktig at informasjonen blir gitt på et så tidlig tidspunkt i svangerskapet som mulig. Konklusjon: Studien viser kompleksiteten av følelser som gravide kvinner kan oppleve i forbindelse med en tidlig ultralydundersøkelse og risikovurdering for kromosomavvik. Disse stressrelaterte følelsene kan sammen med beslutninger på komplisert risikoinformasjon, og på et sterkt ansvarlig og moralsk område vanskeliggjøre beslutningsprosessen. En bedre informasjonsformidling og kontakt med helsevesenet er nødvendig for at kvinnene skal ta informerte valg, som er i tråd med deres verdier og holdninger. Purpose: This qualitative study aimed to increase understanding of how pregnant women experience early ultrasound examination that includes risk assessment for chromosomal anomalies. Moreover, this study examined how such women rationalize test results. Method: I conducted pre- and post-examination interviews of ten pregnant women undergoing risk assessment for chromosomal anomolies, and used grounded theory to analyze the results. Results: The study generated a core category (I want a choice, but I don't want to decide) and five main categories (existential choices, feeling of safety, anxiety, guilt, and counselling and care). Factors contributing to choice difficulty included anxiety, loss of control or coping, emotional connection to the fetus, feelings of guilt, and social pressures. The core category describes the conflict between choice and decision. Since the women sought independent choices without external influence, they also felt greater responsibility. The women's understanding of actual risk varied, and they used different logic and methods to evaluate risk and reach a decision. Conclusion: Pregnant women need for prenatal diagnostic information and want easy access to specialty services. This study shows the complex feelings pregnant women experience regarding early ultrasound examination that includes risk assessment for chromosomal defects. Stress, non-transparent information about actual and perceived risks, and personal moral judgments further complicate the decision-making process. Therefore, improved distribution of information and frequent contact with health professionals will help women to make informed choices in accordance with their values and beliefs.

When examined carefully at the molecular level, the chromosome turns out to have created its own private world full of tricks, back door exits and novel solutions. This "folly" makes it an untamed innovator. Geneticists have been bewildered for decades. What kind of creature was actually the chromosome? Was it plastic, changing by innumerous rearrangements and mutations all the time; or was it a rigid structure which has preserved its basic organisation and functions since the dawn of the cell? It is this conflicting state that seems to be at the base of its "folly". Perplexed by this behavior

Imaginons une société dans laquelle les hommes seraient en majorité plus petits que les femmes (ou les femmes plus grandes que les hommes, selon le point de vue). Impossible, pensons-nous ? Parce que tout ce que fait la Nature est « bien fait »? Et si, en la matière, la Nature était loin de produire des adaptations positives ? Et si, en plus, cette différenciation morphologique n'était pas l'œuvre de la Nature ? Si elle était plutôt l'indice de sélections non naturelles constituées par une entreprise de catégorisation sociale millénaire : le genre ? L'auteur discute dans cet ouvrage des explications évolutives du dimorphisme sexuel de taille corporelle entre mâles et femelles dans le monde vivant. Elle attire l'attention sur l'absence d'un modèle robuste qui rende compte de l'écart sexué de la stature dans l'espèce humaine; en confrontant des données et des modèles disponibles dans des champs disciplinaires éloignés, elle fait peu à peu émerger une hypothèse inédite. Cette recherche illustre le besoin de questionnements transdisciplinaires qui se montrent seuls ici capables de renouveler les termes d'une investigation remarquablement gelée depuis le xixe siècle.
