Low bih weight statistics of a hospital is best shown by-
**Core Concept**
Low birth weight (LBW) is a critical public health concern as it is associated with increased morbidity and mortality in neonates. The World Health Organization (WHO) defines low birth weight as a birth weight of less than 2,500 grams (5.5 pounds).
**Why the Correct Answer is Right**
The most effective way to show low birth weight statistics is by calculating and presenting the prevalence of low birth weight among the total number of births. This can be expressed as a percentage, allowing for easy comparison and interpretation of data across different populations. The prevalence of low birth weight can be calculated by dividing the number of low birth weight births by the total number of births, then multiplying by 100 to obtain a percentage.
**Why Each Wrong Option is Incorrect**
**Option A:**
Calculating the mean birth weight would not provide an accurate representation of low birth weight statistics, as it is a measure of central tendency that can be skewed by extreme values. This method would not account for the proportion of births that are actually low birth weight.
**Option B:**
Presenting the median birth weight would not be an effective way to show low birth weight statistics, as it is a measure of central tendency that can be influenced by outliers. This method would not provide a clear picture of the proportion of births that are low birth weight.
**Option C:**
Reporting the mode birth weight would not be an effective way to show low birth weight statistics, as it is a measure of central tendency that indicates the most frequently occurring value. This method would not account for the proportion of births that are actually low birth weight.
**Clinical Pearl / High-Yield Fact**
The World Health Organization (WHO) recommends that countries establish a birth weight standard of less than 2,500 grams (5.5 pounds) to define low birth weight. This standard is widely accepted and used globally to track and compare low birth weight statistics.
**Correct Answer: D. Prevalence of low birth weight among total number of births.**
