Quick questions on Determinants of young people's health: HSC PDHPE Option

Whether a young person knows what they should do (limit alcohol, attend cervical screening, use sun protection, recognise the signs of depression). School PDHPE is the largest single source for many young Australians. Health literacy is not the same as motivation - knowing what to do is necessary but not sufficient.

Practical capability to act on knowledge. Negotiation skills for safer sex, refusal skills around peer pressure, communication skills for help-seeking, cooking skills for healthy eating, exercise self-management. Skills are taught through practice, not lecture.

What the young person believes about health behaviours. Attitudes are shaped over years by family modelling, peer influence, media exposure, and personal experience. Changing attitudes is harder than changing knowledge.

Risk tolerance, impulsivity, conscientiousness, optimism. Largely stable but interacts with all the other factors.

Genetic predispositions, sex, age. Non-modifiable at the individual level but relevant context for risk.

The single most influential factor for most young Australians. Parental modelling of health behaviours (smoking, drinking, exercise, diet, help-seeking) predicts the young person's behaviour better than school-based education alone. Family connectedness is consistently the strongest protective factor against mental illness, substance use, and risky behaviour in the AIHW Australia's Children and Australia's Youth reports.

Peer influence rises through adolescence and peaks in late adolescence/early adulthood. Peer pressure can be positive (study habits, sport participation, help-seeking culture) or negative (early drinking, drug use, risk-taking). Friendship quality matters more than friendship quantity for mental health outcomes.

A determinant the syllabus has expanded significantly in recent years. Image-based platforms (Instagram, TikTok, Snapchat) correlate with body image concerns and disordered eating in young women in particular. Cyberbullying is a documented risk factor for youth mental illness and suicide attempts.

Cultural and religious community engagement is generally protective for mental health (sense of belonging, intergenerational support, ritual structure). Specific cultures and religions can also create tensions - e.g., around sexual orientation, gender identity, or mental health stigma - that affect specific subgroups of young people.

Higher educational attainment correlates with better health outcomes throughout life. Year 12 completion is the threshold most strongly associated with downstream health benefits. School engagement (not just attendance) is a protective factor against mental illness, substance use, and antisocial behaviour.

Young Australians have the highest unemployment of any age group (roughly double the national average, ABS Labour Force). Employment is protective: it provides routine, income, social contact, identity. Youth unemployment is consistently associated with worse mental health.

Lower-income households experience higher rates of preventable youth health issues - poorer nutrition, higher smoking initiation rates, more housing instability, less access to extracurricular sport. The gap between high- and low-income youth in Australia is widening on several health measures.

Specifically relevant in 2024-2026: rental affordability, food affordability, transport costs. These pressures affect young Australians more than middle-aged Australians because young people earn less and have fewer assets.

Rural and remote young Australians have worse health outcomes across most measures - higher injury rates, less access to mental health services, fewer opportunities for organised sport and recreation, longer travel to GPs and specialists. Suicide rates are roughly three times higher in very remote areas compared to major cities.

GP availability, mental health services, dental services, sexual health clinics. Headspace centres have improved access to youth mental health services but remain unevenly distributed. Bulk-billing rates have declined nationally, raising the gap-fee barrier for low-income young people.
