Using the body mass index as a measure of weight-related health, with data from 2014, age-standardised global prevalence of underweight in women and men were 9.7% and 8.8%, respectively. These values were lower than what was reported for 1975 as 14.6% and 13.8%, respectively, indicating a worldwide reduction in the extent of undernutrition. [6]
Stunted growth, also known as stunting or linear growth failure, is defined as impaired growth and development manifested by low height-for-age.
