-Adult [[start|Lifelines]] participants completed [[1A|baseline]] questions on a broad range of topics, enabling researchers from the [[https://www.rug.nl/staff/a.v.ballering/research|University Medical Center Groningen]] to calculate a gender index. This index is a continuum, ranging from 0% (masculinity) to 100% (femininity). A gender index of 50% indicates androgyny, where equal levels of feminine and masculine characteristics are present ([[sections]]: [[demographics]] ([[sex & gender]]) and [[secondary & linked variables]]).
+Researchers from the [[https://www.rug.nl/staff/a.v.ballering/research|University Medical Center Groningen]] calculated a gender index for adult [[start|Lifelines]] participants based on [[1A|baseline]] questions on a broad range of topics, in order to facilitate the research into the role of gender versus sex in healthy ageing.\\
+Notably, biological [[https://en.wikipedia.org/wiki/Sex|sex]] and psychosocial [[https://en.wikipedia.org/wiki/Gender|gender]] are not the same concepts. Sex refers to the biological characteristics, included but not limited to genes, anatomy, hormones of males and females. Gender, in contrast, entails the embodiment of different roles, behaviors, identities, and relationships of men and women prescribed by societal norms, that result in different social expectations, opportunities and experiences for women and men in a given society. Gender and its embodiment is dynamic over time, while biological sex is mostly stable.\\
