Osteoporosis is a huge public health problem for menopausal women all over the world, both in developing and in developed countries. Roughly one in three menopausal women suffers from osteoporosis and one in two from osteopenia. Prevention is the main stay for osteoporosis. It is very important to study all aspects of a woman’s life that can lead to later development of postmenopausal osteoporosis.
Osteoporosis has been studied extensively in relationship to ethnicity, geographical variations and estrogen depletion in menopause. However, the negative relationship of lactation duration and effect of pregnancies with postmenopausal osteoporosis is still inconclusive. The definite role of hormone replacement therapy in the prevention of osteoporosis is now a resolved issue. In a study by Hwang and colleagues , a cross-sectional survey based on the Korea National Health and Nutrition Examination Survey (KNHANES) 2010 and 2011 data (n = 1222 postmenopausal women), showed that a duration of breastfeeding longer than 37 months was associated with higher prevalence of osteoporosis in postmenopause and more fractures of the lumbar spine. A duration of lactation longer than 37 months was associated with low bone mineral density (BMD) in the lumbar spine and hip; the number of spinal fractures was increased (37 or more months, odds ratio (OR) 3.292; 95% confidence interval (CI) 1.485–7.23). But, interestingly, the number of deliveries had no relationship with postmenopausal BMD.
