Abstract:
BACKGROUND:Aging, lack of estrogen and few activities may lead to the decrease of resting energy expenditure in menopause women so as to induce the body composition changes, which can result in disease, such as obesity and fracture. OBJECTIVE:To explore the change of body composition and resting metabolic rate among premenopausal, perimenopausal and postmenopausal women. METHODS:2 312 women who came to outpatient clinic were recruited, including 1 310 premenopausal women, 790 perimenopausal women and 212 postmenopausal women. Body composition and resting energy expenditure were measured in each woman. RESULTS AND CONCLUSION:(1) Body fat percentage of perimenopausal and postmenopausal women was significantly higher than that of pre-menopausal women. (2) There was no significant difference in resting metabolic rate among the three groups. When adjusted body weight, the resting energy expenditure per kilogram was significantly lower in perimenopausal women than in premenopausal women. (3) Bone mineral density, femoral neck strength, lower limb maximal strength, and leg muscle distribution coefficient were significantly lower in postmenopausal women than in perimenopausal and premenopausal women (P < 0.05). (4) Weight and leg muscle distribution coefficient were positively correlated with the resting energy expenditure per kilogram, and height, body mass index, body fat percentage were negatively correlated with the resting energy expenditure per kilogram. These findings indicate that the body composition can change in women after menopause, such as body fat increasing, muscle content decreasing, and bone mass loss. There is a certain relationship between the change in body composition and resting energy expenditure.
