A community has a population of 10,000 and a birth rate of 36 per 1000. 5 maternal deaths were reported in the current year. The MMR is
First, I need to recall the formula for MMR. MMR is typically calculated as the number of maternal deaths per 100,000 live births. So the formula is (Number of maternal deaths / Number of live births) × 100,000.
The population is 10,000. The birth rate is 36 per 1000, which means for every 1000 people, there are 36 births. To find the total number of live births in the community, I multiply 36 by the population divided by 1000. So 36/1000 * 10,000 = 360 live births.
Now, using the MMR formula: (5 maternal deaths / 360 live births) × 100,000. Let's compute that. 5 divided by 360 is approximately 0.013888... Multiply by 100,000 gives 1388.88... So the MMR is approximately 1389 per 100,000 live births. Since the options aren't given, the correct answer would be around this number.
Wait, but the options might be in different formats. Let me check if I did the calculation correctly. Yes, 36 per 1000 is 3.6% birth rate. 10,000 population gives 360 live births. 5 deaths divided by 360 is 0.013888... Multiply by 100,000 gives 1388.89, so 1389. So the answer is approximately 1390 per 100,000 live births.
Now, the user wants the explanation. Let me structure it according to their guidelines. The core concept is the formula for MMR. The correct answer is right because it uses the correct formula. The wrong options might be based on using population instead of live births or incorrect rates. The clinical pearl is to remember the denominator is live births, not total population. The correct answer is 1390.
**Core Concept**
Maternal Mortality Rate (MMR) is defined as the number of maternal deaths per 100,000 live births during a specific time period. It is a critical public health indicator reflecting maternal healthcare quality.
**Why the Correct Answer is Right**
Given a population of 10,000 and a birth rate of 36 per 1,000, total live births = (36/1,000) × 10,000 = 360. MMR is calculated as (Maternal deaths / Live births) × 100,000. Substituting values:
