Hypothesis

Does calcium supplementation affect obesity or body composition in postmenopausal women?

Conclusion

Calcium supplementation over four years has a beneficial effect on body composition in postmenopausal women.

Supporting Evidence

  • Calcium intervention groups gained less trunk fat and maintained more trunk lean compared to the placebo group.
  • Changes in trunk fat, trunk lean, and percentage of trunk fat were significantly different between the calcium intervention groups and the placebo group.

Takeaway

Taking calcium can help older women keep their bodies healthier by reducing fat and keeping muscle.

Limitations

The study lacked records of energy intake and physical activity.
