The association between daily calcium intake and sarcopenia in older, non-obese Korean adults: the fourth Korea National Health and Nutrition Examination Survey (KNHANES IV) 2009.
Recent data suggest that variations in calcium intake may influence body weight and composition; however, the relationship between daily calcium intake and muscle mass has not been well established. The objective of this study was to assess the relationship between daily calcium intake and sarcopenia. We analyzed data for older adults (over 60 years) from the fourth Korea National Health and Nutrition Examination Survey (KNHANES) conducted in 2009. A total of 1339 Non-Obese (BMI between 18.5 and 25 kg/m²), older adults (592 men and 707 women) were enrolled. Dietary variables were assessed using a nutrition survey that used a 24-hour recall method. Daily calcium intake based on the consumption of each food item was calculated. Sarcopenia was defined as an appendicular skeletal muscle mass divided by body weight less than 2 SD below the sex-specific mean for young adults. We found that daily calcium intake was negatively correlated with total body fat percentage and positively correlated with appendicular skeletal mass (p<0.001). Participants with sarcopenia appear to have significantly lower daily calcium intakes than participants without sarcopenia (p<0.001). The unadjusted prevalence of sarcopenia according to daily calcium intake tertiles were 6.3%, 4.3%, and 2.7% in tertiles 1, 2, and 3, respectively. After adjustment for age, sex, BMI, total energy intake, and lifestyle factors, compared with those in the lowest tertile of daily calcium intake, participants in the highest tertile had an odds ratio for sarcopenia of 0.295 (95% confidence interval, 0.087-0.768; p for trend = 0.014). We found that daily calcium intake, corrected for total energy intake and serum 25(OH)D status, was significantly lower in subjects with sarcopenia than in those without. Our results suggest a strong inverse association between daily calcium intake and sarcopenia in non-obese, older Korean adults.
