After one month, data were gathered again and then analized. Results: The mean age of case and control groups were 26.7 ± 4.7 and 23.4 ± 4.4 years respectively and mean duration of gestation was 23.2 ± 11 and 23.4 ± 10 weeks respectively and there was no significant difference between them (p>0.05). Research findings showed that knowledge and self-efficasy health behavior action for osteoprosis pervention were in low stage. After intervention, perceived barriers decreased in case group and pregnant mothers and health behavior action for osteoprosis pervention increased. Conclusion: With knowledge, perceived susceptibility, severity and benefits and self efficasy increased, perceived barriers decreased and health behavior action for osteoprosis pervention  increased.
