School health check up comes under ……….. level of prevention-

Correct option is C

School health check-up is categorized under the secondary level of prevention in public health. Secondary prevention focuses on early detection and prompt treatment of diseases to halt or slow the progression of illness in its earliest stages.

During school health programs, routine check-ups help in:

• Screening for visual defects, anemia, dental issues, nutritional deficiencies, skin diseases, and hearing problems.
• Identifying early signs of physical or mental developmental delays.
• Referring students for further treatment if abnormalities are found.

Thus, the goal is early diagnosis and treatment, which squarely fits within secondary prevention.

Explanation of Each Option:

• (a) Primordial –
  Refers to actions taken to prevent the emergence of risk factors (e.g., promoting healthy eating habits in early childhood). School health check-ups occur after risk factors may have developed.
• (b) Primary –
  Involves preventing the onset of disease, such as immunizations and health education. While school health programs may include these, the check-up or screening part is diagnostic, not preventive.
• (c) Secondary –
  Involves screening and early diagnosis, exactly what school health check-ups are intended to do. This level focuses on identifying conditions before symptoms appear and preventing complications.
• (d) Tertiary –
  This is about rehabilitation and managing established disease, such as physical therapy or long-term treatment—not applicable in general school check-ups.
