Pubertal Development and Adolescent Mental Health

Pubertal development represents a complex interplay of hormonal, physical and neural changes that transform a child into a reproductively mature adolescent. This period is marked by activation of the hypothalamic–pituitary–gonadal and hypothalamic–pituitary–adrenal axes, resulting in surges of sex steroids and adrenal androgens. These endocrine shifts coincide with dramatic remodelling of brain circuits involved in emotion regulation, social cognition and reward processing. As a result, puberty is not only a window of physical maturation but also a sensitive period for the emergence or exacerbation of mental health problems. Early or late timing relative to peers, rapid progression through pubertal stages and asynchronous development of hormone levels and physical features have all been linked to elevated risk of depression, anxiety, self‐harm and behavioural problems. Increasing evidence points to both biological pathways, including changes in gene expression, neuroinflammation and neurotransmitter systems, and psychosocial factors such as peer relationships, body image and family environment. Understanding the multidimensional nature of this transition is essential for identifying young people at heightened risk and for designing timely interventions to promote resilience and well‐being.

Research from Nature Portfolio

Recent studies have begun to chart the molecular landscape of puberty, revealing how systemic changes may underlie shifts in vulnerability to mental health disturbances. Longitudinal profiling of immune cell gene expression in a paediatric cohort demonstrated that the transition through menarche is accompanied by a marked shift from innate to adaptive immunity. These transcriptional changes were found to interact with genetic variants, suggesting that individual differences in pubertal timing can modulate immune responses. By linking gene expression trajectories to hormone levels and developmental stage, this work offers a paradigm for integrating molecular and endocrine data. Such approaches promise to elucidate how hormonal surges during puberty may prime neuroimmune pathways that contribute to mood dysregulation and stress sensitivity in adolescence.

Pubertal Development and Adolescent Mental Health publication trend

The graph below shows the total number of articles in pubertal development and adolescent mental health across all publications each year (not limited to Nature Index journals).

Technical terms

Pubertal timing: The relative onset of pubertal milestones (e.g. breast development, voice change) compared with age‐matched peers.

Menarche: The first menstrual bleed in females, marking a key event in pubertal maturation.

Innate immunity: The body’s first line of defence, comprising non-specific cellular and molecular responses to pathogens.

Adaptive immunity: A specialised immune system component that develops memory and specificity to particular antigens over time.

Mendelian randomisation: A causal inference technique that uses genetic variants as proxies for modifiable exposures to assess their impact on outcomes.
