Objective:
To analyse the correlation of dietary factors with haemoglobin concentration and body mass index.
Methods:
This cross-sectional study was conducted in Shaheed Benazirabad district of the Sindh province in Pakistan from September 2015 to April 2016, and comprised students randomly selected from government schools. Data concerning dietary intake, such as meat, milk, egg and fruits, was noted. Baseline data was compared with haemoglobin and serum ferritin levels. Data was analysed using SPSS 20.
Results:
There were 1686 subjects aged 11-18 years; 946(56%) boys and 740(44%) girls. Dietary factors, such as meat, egg and fruits, showed significant association with haemoglobin, serum ferritin levels as well as with Body Mass Index and monthly household income (p<0.05). However, milk consumption had non-significant association with haemoglobin (9p>0.05).
Conclusions:
Iron status in blood was found to be significantly affected by dietary intake, such as meat, milk, fruits and eggs.

Factors Affecting Erythropoiesis
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.
