Which of the following is NOT a socio economic indicator of health care?
**Core Concept**
The question is testing the understanding of socio-economic indicators of healthcare, which are measures used to assess the health outcomes and access to healthcare services in different populations. These indicators can provide valuable insights into the relationship between social determinants and health outcomes.
**Why the Correct Answer is Right**
The correct answer is **Life expectancy at birth**. Life expectancy at birth is a demographic indicator that measures the average number of years a person is expected to live at birth. While it is an important indicator of population health, it is not a socio-economic indicator of healthcare. Socio-economic indicators of healthcare typically focus on access to healthcare services, health outcomes, and health inequities among different populations.
**Why Each Wrong Option is Incorrect**
* **Option A:** Infant mortality rate is a socio-economic indicator of healthcare, as it reflects the number of deaths per 1,000 live births in the first year of life. It is often used to assess the quality of healthcare services and the overall health of a population.
* **Option B:** Maternal mortality ratio is another socio-economic indicator of healthcare, as it measures the number of deaths per 100,000 live births due to pregnancy-related complications. It is an important indicator of the quality of maternal healthcare services.
* **Option C:** Healthcare expenditure as a percentage of GDP is a socio-economic indicator of healthcare, as it reflects the proportion of a country's GDP spent on healthcare services. It is often used to assess the financial burden of healthcare on individuals and societies.
**Clinical Pearl / High-Yield Fact**
Socio-economic indicators of healthcare are essential for understanding health inequities and for developing targeted interventions to improve health outcomes. By tracking these indicators over time, policymakers can identify areas where healthcare services need to be improved or expanded.
**Correct Answer: D. Life expectancy at birth.**
