A toxic cocktail of five or more hours of daily screen time, indoor lifestyles, and widespread vitamin D deficiency is crippling bone deposition
“The foundation for an adult’s skeletal strength is built during childhood, with nearly 90% of peak bone mass acquired by age 18. Childhood and adolescence are particularly important, as a significant proportion of peak bone mass is built by the age of 18.
“I believe we are looking at bone health too late,” said Dr Vishal Chaudhari, senior orthopaedic consultant and HOD of orthopaedics at Noble Hospital. “Bone mass accrued during childhood depends on four key factors: genetics, nutrition, sunlight, and physical activity,” said Dr Uday Phadke, director and chief consultant, department of endocrinology and diabetes at Sahyadri Super Speciality Hospital. We cannot expect strong bones from a childhood spent largely indoors, sitting for hours and missing opportunities to run, jump, and play. These everyday movements are not merely recreation; they are vital stimuli for developing bones. Alongside adequate nutrition and addressing vitamin D deficiency, we must make active play a priority. “While we cannot control our genetic predisposition, the other three factors are largely influenced by our daily habits. A balanced diet rich in calcium and adequate protein, sufficient sunlight exposure to support vitamin D synthesis, and regular weight-bearing exercises are essential for healthy bone development. With increasing screen time and reduced outdoor play, children risk missing this crucial window. Building strong bones early is an investment in lifelong skeletal health.”
The strongest prescription for future bone health may begin long before a child ever meets a doctor. Global data analysis shows that osteoporosis causes more annual hospitalisations than breast cancer, heart disease, or stroke combined. several can be controlled early in life While multiple factors affect bone mass.
