Interpreting a Widening Life Expectancy Gap
A country's national health survey reports that life expectancy rose from 74.1 to 77.8 years between 2005 and 2020. The same report shows the gap between the highest and lowest socioeconomic quintiles widened from 3.2 to 5.6 years over that period. Self-reported chronic illness rose from 18% to 27% of adults, with the largest increase among the lowest quintile (from 31% to 49%). Over the same years, the government expanded free screening programs and built two new tertiary hospitals in the capital, while rural clinics reported falling staffing levels. A minister cites the rising national life expectancy as evidence that health and wellbeing is improving for all citizens.
1. Using the concepts of health status and burden of disease, evaluate the minister's claim.
Read the worked answer
The minister's claim conflates a population average with the distribution of health. Health status is the overall level of health of an individual or population measured against indicators; a rising national life expectancy is a genuine improvement in that indicator, so the claim is partly supported. However, health status also includes morbidity. Chronic illness rising from 18% to 27% indicates more years lived with disease, and the concentration of that rise in the lowest quintile (31% to 49%) signals worsening inequality. Burden of disease combines fatal and non-fatal impacts; a widening life expectancy gap plus rising chronic illness suggests the non-fatal and premature-mortality burden is shifting toward disadvantaged groups. Because averages hide distribution, the correct judgement is that average health status improved while equity in health status deteriorated. The claim 'for all citizens' is not supported.
2. Explain how two features of the described health system could have contributed to the widening gap rather than narrowing it.

First, the expansion of tertiary hospitals and screening in the capital reflects a curative, urban-centred approach. Screening only reduces burden if followed by accessible treatment; rural residents facing distance and cost may be diagnosed later, so survival gains accrue disproportionately to urban and higher-income groups. Second, falling rural clinic staffing reduces access to primary health care, the level of care most effective at managing chronic disease and preventing complications. With fewer staff, continuity of care weakens, chronic illness prevalence rises, and premature mortality increases in exactly the lowest quintile. Together these features show that resource allocation choices, not just total spending, shape equity. The programs were not designed with an equity lens (for example, outreach, transport support, or rural workforce incentives), so they amplified existing advantage.
