Effect of Multiparity and Prolonged Lactation on Bone Mineral Density

OBJECTIVES This study was done to determine the effect of multiparity and prolonged lactation on bone mineral density (BMD). METHODS This cross-sectional study included 196 perimenopausal and postmenopausal women aged 40 to 60 years old. Age, body mass index (BMI), menopausal status, duration of menopause, parity and total duration of lactation, nutritional history were recorded. Lumbar spine...

[Pregnancy, lactation and bone mineral density].

Evidence shows that pregnancy and lactation lead to the decrease of bone mineral density (BMD), which is related to mobilization of skeletal calcium. Numeorous mechanisms are involved in maternal adaptation to the increased demand for calcium. BMD has been proved to return to the baseline level after weaning. Pregnancies and long or repeated periods of feeding do not seem to determine the diagn...

Effects of multiparity and prolonged breast-feeding on maternal bone mineral density: a community-based cross-sectional study

BACKGROUND Studies conducted in Western countries have shown that bone loss associated with pregnancy and breast-feeding is recovered after weaning. However, it is not clear whether recovery takes place after repeated pregnancies followed by prolonged periods of breast-feeding; especially in developing countries where nutritional intake is comparatively low.This study was designed to examine th...

Effect of exercise training on loss of bone mineral density during lactation.

PURPOSE During lactation, women transfer approximately 200 mg of calcium per day to breast milk. For 6 months, this is equivalent to 3%-9% of bone mineral density (BMD) loss at trabecular-rich sites. Bone mass usually returns to prepregnancy levels with cessation of lactation but not in all women. Therefore, the purpose of this study was to determine whether exercise slows bone loss from 4 to 2...
