The effect of lifestyle on some non-communicable diseases: discuss the human and financial cost of these non- communicable diseases to an individual, a local community, a nation or globally

The idea

Non-communicable diseases cannot be passed between people, yet they still impose heavy costs. Human cost means suffering: pain, reduced mobility, anxiety, stigma, lost independence and premature death. Financial cost means money spent or income lost. For an individual, this could be paying for medicines, transport to hospital or adapting a home, plus lost wages. A local community may lose a carer or volunteer and fundraise for treatment. A nation pays for NHS staff, screening and long-term care, and loses tax revenue when workers are ill. Globally, low-income countries may struggle to afford prevention and treatment. A useful method is to name the disease, then trace one human and one financial consequence at each level, using a concrete example such as type 2 diabetes or lung cancer.

What earns the marks

• Distinguishes human cost (suffering, pain, anxiety, stigma, reduced quality of life, premature death) from financial cost (direct treatment costs and indirect lost income or productivity).
• Applies the distinction at more than one level, for example an individual paying for insulin versus a nation funding diabetes care and losing tax revenue.
• Uses a named non-communicable disease, such as type 2 diabetes, coronary heart disease, lung cancer or chronic obstructive pulmonary disease, to make the discussion concrete.
• Recognises that costs interact: illness can reduce a person's income, which worsens health outcomes and increases the burden on public services.
• Considers prevention as a way to reduce cost, for example anti-smoking campaigns or sugar reduction, and links this to lower future spending.
• Reaches a supported judgement about which level carries the greatest cost, rather than listing points without comparison.

Common mistakes and how to put them right

• Treating all disease cost as financial only.

  Put it right: Human cost includes pain, anxiety, stigma and lost independence, which are not measured in money.

• Assuming non-communicable diseases affect only wealthy countries.

  Put it right: They cause a large share of deaths worldwide, including in low- and middle-income countries.

• Confusing non-communicable with infectious disease.

  Put it right: Non-communicable diseases are not passed from person to person, so costs arise from long-term care rather than transmission.

• Giving a vague statement such as 'it costs a lot'.

  Put it right: Specify who pays and for what, for example a family paying for transport to dialysis.

Exam tips

• Use the levels in the question as paragraph prompts: individual, local community, nation, global.
• Include both human and financial consequences for each level you discuss to show balance.
• Anchor each point to a named disease so the discussion stays specific and creditworthy.
• Finish with a short comparative judgement rather than a new point.
