Calcium intake is inversely associated with body fat in postmenopausal women

Abstract

Background & aims: Calcium intake seems to be inversely associated with body fat in several populations; however, little is known about this relationship in postmenopausal women. This study aimed to associate calcium intake with body fat mass in postmenopausal women.

Methods: A cross-sectional study was performed with 107 postmenopausal women who entered in a lifestyle change program. The dietary intake was estimated through three 24-h food recalls. Body fat mass was evaluated by dual-energy X-ray absorptiometry (DXA). Linear regression analyzes were performed associating body fat variables (total fat mass, body fat percentage, trunk fat, gynoid and android fat mass; and body mass index) with calcium intake.

Results: After adjustments for age; carbohydrate, protein, lipids and fiber intakes; and physical activity, it was observed that calcium intake (mg/day) was inversely associated with total fat mass (kg and percentage), trunk fat mass (kg), gynoid and android fat mass (kg). Calcium intake was not associated with body mass index, although a tendency was observed (p = 0.062).

Conclusion: Calcium intake was inversely associated with body fat mass in postmenopausal women.
