Abstract
Objective The goal of this study was to examine the purported effects of calcium on modulating body weight. Design Retrospective data was used to assess the relationship between calcium intake and weight change over an 8- to 12-year period among middle-aged adults. Subjects Participants were 10,591 men and women aged 53 to 57 years recruited during 2000-2002. Statistical Analysis Linear regression was used to model associations of 10-year weight change and calcium intake, adjusted for weight at age 45 years, energy intake, physical activity, and other factors. Results Calcium intake was associated with 10-year weight change only in women. Women with current calcium supplement dose of >500 mg/day had a 10-year weight gain of 5.1 kg (95% confidence interval 4.7 to 5.5) compared to 6.9 kg (95% confidence interval 6.5 to 7.4) among nonusers ( P for trend=0.001). Trends were similar for total calcium intake from diet plus supplements ( P for trend=0.001). Dietary calcium alone had no significant effect on 10-year weight change. Conclusions Increasing total calcium intake, in the form of calcium supplementation, may be beneficial to weight maintenance, especially in women during midlife.
