Which of the following does NOT affect growth spurts?

• A. High grades
• B. Genetics
• C. Socioeconomic status
• D. Nutrition

Answer: (A)

Growth spurts during puberty are driven by hormonal changes that come from genetics, with nutrition and overall health shaping how well the body develops. High grades don’t influence these hormonal processes, so they don’t affect when or how much someone grows. Genetics largely determines the timing and pattern of growth, while good nutrition provides the building blocks for growth and lack of adequate nutrition can limit it. Socioeconomic status can influence access to nutritious food and health care, which can impact growth outcomes, but it isn’t a direct driver of growth spurts itself.
