Conference on 'Understanding the role of sex and gender in nutrition research'

Nutrition plays a pivotal role in health and disease prevention and management and through its interactions with social and personal factors, influences an individual's growth, development and life chances, as well as long-term health and longevity. These factors include amongst others, genetic inheritance, ethnicity, socio-cultural context, sex and gender. Although different interpretations exist, in general sex refers to the genetic, biological and physiological attributes that distinguish females, males and intersex whereas gender refers to socio-cultural and politically constructed roles and behaviours associated with a feminine, masculine or non-binary identity, which vary from society to society. Sex has implications for key biological processes involving food and nutrients as well as life-stage differences in nutritional requirements. Sex and gender may have implications in how individuals engage in different dietary behaviours and respond to nutrition interventions. The Irish Section Nutrition Society 2023 Conference sought to enhance understanding of the role of sex and gender in nutrition research; explore the influence of sex and gender on risk of non-communicable diseases and examine sex- and gender-specific considerations across the life course. This short editorial provides an overview and highlights of the conference.
