Highest maternal moality is associated with:
**Core Concept**
The question is testing the association between maternal mortality and various risk factors, highlighting the importance of identifying high-risk pregnancies and conditions that contribute to maternal morbidity and mortality. Maternal mortality is a critical public health concern, and understanding its causes is essential for improving maternal health outcomes.
**Why the Correct Answer is Right**
The correct answer is **A. Abortion**. Unsafe abortion is a leading cause of maternal mortality worldwide, particularly in regions where access to safe and legal abortion services is restricted. The World Health Organization (WHO) estimates that approximately 22 million unsafe abortions occur annually, resulting in significant maternal morbidity and mortality. The high mortality rate associated with abortion is attributed to the risks of hemorrhage, infection, and other complications arising from the procedure itself or the underlying conditions that necessitate abortion.
**Why Each Wrong Option is Incorrect**
* **Option B:** **Cardiovascular disease** is a significant risk factor for maternal mortality, particularly in developed countries. However, it is not the highest maternal mortality risk factor globally. Cardiovascular disease accounts for a substantial proportion of maternal deaths, particularly in women with pre-existing conditions or those who develop cardiovascular complications during pregnancy.
* **Option C:** **HIV/AIDS** is a significant public health concern, and HIV-positive women are at increased risk of maternal mortality due to complications such as preterm labor, low birth weight, and postpartum hemorrhage. However, HIV/AIDS is not the highest maternal mortality risk factor. While HIV/AIDS is a critical concern, the mortality risk associated with HIV is lower than that of unsafe abortion.
**Clinical Pearl / High-Yield Fact**
In regions with restricted access to safe abortion services, maternal mortality rates are significantly higher. The World Health Organization (WHO) recommends ensuring safe and accessible abortion services as a key strategy to reduce maternal mortality.
**Correct Answer:** A. Abortion.
