Adolescence is a developmental stage marked by heightened sensitivity to peers’ perceptions and social expectations (Steinberg and Monahan, 2007[36]), during which femininity and masculinity norms1 can strongly shape girls’ and boys’ identities, sense of self, and overall subjective well-being (Al-Attar et al., 2017[37]; De Meyer et al., 2017[38]; Kågesten et al., 2016[39]; Bussey and Bandura, 1999[40]; Hyde et al., 2019[41]). Navigating these expectations is especially challenging at this age. Young people undergo profound physical and hormonal changes associated with puberty (Galambos, Almeida and Petersen, 1990[42]; Patton et al., 2016[43]), while simultaneously confronting multiple – and often conflicting – messages about appropriate attitudes and ideals conveyed by family, peers, media, and wider society (Tiggemann and Slater, 2015[44]; Vandenbosch and Eggermont, 2012[45]). These pressures may clash with adolescents’ own emotions, experiences, and emerging identities, generating tension as they strive to reconcile social expectations with their developing sense of self (Crocetti et al., 2022[46]). Such dissonance can contribute to psychological distress and increase vulnerability to mental health difficulties (Xu, Feng and Rahman, 2024[47]). It can also erode self-confidence, self-awareness, and the formation of a positive self-concept, with implications that extend beyond mental health to affect adolescents’ engagement in learning and their relationships at school, within their families, and in their broader social lives (Cairns and Cairns, 1994[48]; Patton et al., 2016[43]; McGorry et al., 2024[1]).
Norms play a dual role in adolescents’ development: they can provide valuable reference points for shaping a sense of self and social identity, yet they also pose challenges when they reinforce expectations to conform to rigid stereotypes.2 On the one hand, positive and flexible norms can support adolescents’ social and emotional well-being by encouraging authenticity and self-expression. On the other hand, when norms and stereotypes become too rigid, they may restrict adolescents’ personal development, limit their opportunities for self-expression, marginalise those who do not conform, and reinforce broader inequalities in learning motivation, engagement and achievement between boys and girls (Exner-Cortens et al., 2021[49]; Yu, McLellan and Winter, 2020[50]). Dismantling such restrictive norms and stereotypes – particularly in educational settings – is therefore essential for narrowing gaps in learning outcomes and career pathways (Brussino and McBrien, 2022[51]).
Social norms associated with being male or female have generally become more flexible over the past several decades, yet recent years have seen a resurgence of more restrictive and discriminatory stereotypes that promote inflexible notions of what it means to belong to a particular sex. For example, femininity is still widely associated with appearance consciousness, kindness, and care – traits used to justify women’s primary responsibility for caretaking roles. Conversely, traditionally masculine traits such as stoicism, competitiveness, and physical strength are often linked to expectations that men should be the main decision makers and breadwinners (OECD, 2024[52]). Evidence of a renewed attachment to traditional femininity and masculinity norms is also reflected in the attitudes of younger adults toward women’s suitability for leadership positions. In G7 countries, adults aged 18‑34 are less likely than older generations to agree that women are equally suited for leadership roles (Verian Group, 2024[53]).
Stereotypical views are also widespread among children and adolescents. A large proportion 15‑year‑olds surveyed globally in 2023 agreed with sex-related stereotypes, such as girls and boys having inherently different temperaments with regard to sensitivity (49%), empathy (43%), and aggressivity (42%), and women being better suited to caring for children than men (46%) – and more boys agree more with sex-related stereotypes than girls (OECD, 2024[54]). Beliefs about what is appropriate for boys and girls held in adolescence can shape life‑long patterns of stereotyping (UNICEF, 2020[55]). These enduring norms continue to influence educational pathways and career choices (Brussino and McBrien, 2022[51]), as well as broader social and economic outcomes. For example, women continue to spend disproportionate time on unpaid care and housework and face lower employment rates and wages, while men have persistently higher suicide rates (OECD, 2023[56]). Understanding how femininity and masculinity norms influence expectations and behaviours from the earliest stages of life is therefore essential.
It should be noted that femininity and masculinity norms and stereotypes are not the sole drivers of gaps in adolescent boys’ and girls’ social and emotional well-being, nor are they homogeneous across the OECD. Firstly, while general trends emerge in the available data, boys’ and girl’s socialisation remains dependent upon highly variable socio-contextual factors, across and within OECD countries (Torsheim et al., 2006[57]). Additionally, socialisation is intertwined with various developmental, psychological, and hormonal factors that emerge in adolescence and that also play a significant role in shaping sex-specific challenges in this life stage (UK Department for Education, 2019[58]). This can make it difficult to isolate the specific influences of femininity and masculinity norms on adolescent well-being.
Restrictive femininity norms3 intensify pressures on girls’ bodies, self-esteem, and achievement. Norms and stereotypes, combined with the multiple and often conflicting pressures that adolescents face, exert a particularly strong influence on how girls perceive their bodies and how they experience and internalise academic pressure (Landstedt, Asplund and Gillander Gådin, 2009[59]). Conflicting expectations make it particularly difficult to conform to them with no stress. They may be expected to embody traditional feminine qualities – such as being caring, kind, and appearance‑focussed – while simultaneously being encouraged to adopt traits more commonly associated with traditional masculinity, including autonomy, toughness, and stoicism, which tend to be more socially rewarded (Rogers et al., 2019[60]). Norms of femininity can clash with concurrent cultural expectations of performance and perfection embedded within schools (Stentiford, Koutsouris and Allan, 2021[61]). This tension between competing ideals can heighten insecurity, self-doubt, and emotional strain during a developmental period already marked by vulnerability.
Girls tend to experience more anxieties and dissatisfactions related to their appearance than boys, reflecting higher levels of scrutiny and sexualisation over their bodies through social, marketing, and media influences (Smolak, 2004[62]) (Box 2). In France, a study conducted in 2015 in adolescents aged 15 to 18 found that 95% of girls, against 86% of boys, thought that the media imposed a certain body image, and that 81% of girls, against 71% of boys, thought that being attractive was preferable to succeed in life (Ipsos, 2015[63]). Similarly, in most OECD countries, more adolescent girls than boys believe that their body is much too thin or much too fat (Figure 6). Among 15‑year‑olds in seven OECD countries, 43% of girls are dissatisfied with the way that they look, compared to 24% of boys on average (Thévenon, Brüning and Matsumura, 2025[64]). As a result, practices such as makeup and shaving, which derive from pressures to conform to femininity norms, can start in adolescence (Demkowicz et al., 2025[65]). In some cases, these norms can go as far as to encourage dangerous practices, such as when the societal valorisation of thinness increases adolescents’ risk of anorexia (American Psychiatric Association, 2013[25]). Negative body image in adolescents has consistently been linked to lower subjective well-being and self-esteem, heightened levels of distress, and depressive symptoms, as well as mental health conditions such as eating disorders (Neumark-Sztainer et al., 2006[66]; Stice et al., 2017[67]; Baker et al., 2019[68]).
