Final answer:
Pregnant adolescents with low BMIs due to "fad" dieting are at high risk for having low-birth-weight babies, which can lead to serious health complications and developmental delays for the child.
Step-by-step explanation:
Pregnant adolescents are at high risk for low-birth-weight babies due to lower body mass indexes (BMIs) and "fad" dieting. This condition is particularly concerning as it carries significant risks for the health of both the mother and child. Maternal undernutrition and intrauterine growth restriction, both of which can be consequences of low BMI and improper dieting, can lead to babies being born with low birth weight (less than 2.5 kg, or 5.5 lb.). Such infants are more susceptible to disease and have a higher risk of mortality in infancy. Furthermore, for those who survive, it may result in slow growth and developmental delays during childhood. Pregnant adolescents should, therefore, be carefully monitored to ensure they have healthy nutrition habits to minimize the risks.
Pregnant adolescents are at high risk for low-birth-weight babies due to lower body mass indexes (BMIs) and "fad" dieting. Low birth weight is defined as body weight at least 20 percent higher than a healthy weight for a child of that height. The condition of being extremely overweight or obese, known as obesity, can have negative effects on health and is associated with several risks, including low-birth-weight babies.
