[Prevention of osteoporosis during pregnancy and lactation period.]

Post-pregnant osteoporosis, characterized by low back pain and vertebral fractures, is a relatively rare disease. For avoiding post-pregnant osteoporosis and decrease in bone mass during pregnancy or lactation period, it is necessary to obtain sufficient bone mass during the growth period and maintain bone mass in adulthood. From the results of the national nutrition and health survey, the total energy, protein, calcium intake of women aged 20s and 30s is the lowest in all ages. In addition, young women with exercise habits are less than 10%. In addition to the prevention of post-pregnant osteoporosis, to avoid future osteoporosis and fragility fractures of older age, it is necessary to promote young women to take measures such as adequate nutrition intake and exercise habits, considering bone health.
