Background: The Osteoporosis is a major global public health concern, particularly in developing countries, driven by rising levels of obesity, poor nutrition, and physical inactivity. Methodology: The study used a quantitative quasi-experimental pretest–posttest control group design. It was conducted among 100 premenopausal women aged 35–50 years in Orleanpet and Lawspet, Puducherry, with 50 participants each in the experimental and control groups. Results: At baseline, 62% of women in the experimental group and 70% in the control group had inadequate knowledge, with most exhibiting neutral attitudes and poor osteoporosis preventive practices. After Video Assisted Teaching, 54% attained adequate knowledge, 88% developed a positive attitude, and adequate practices increased to 94% for sunlight exposure, 92% for calcium intake, and 72% each for vitamin D intake and physical activity. Post-test differences between groups were highly significant for sunlight exposure (t = 9.646), calcium intake (t = 5.588), vitamin D intake (t = 3.964), and physical activity (t = 4.272) at p = 0.0001, confirming the effectiveness of Video Assisted Teaching. Conclusion: The study concluded that Video Assisted Teaching was highly effective in improving knowledge, attitude, and lifestyle practices regarding prevention strategies of osteoporosis among premenopausal women.
