- Abstract
Background: The proportion of sarcopenia in the elderly is very high, although muscle mass loss before sarcopenia covers a wider population. The present study aimed to analyse the effects of different dietary patterns on muscle mass. Methods: In both 2015 and 2018, using multilayer random sampling, the same participants were selected, and the same questionnaires and machines were used. Results: In total, 502 participants were selected. The >65‐year‐old group showed maximum muscle mass loss in males and females (−1.53 kg ± 4.42 and −1.14 kg ± 2.6 on average, respectively). The cumulative variance of four dietary patterns reached 52.28%. Logistical regression revealed significant differences between ʻJiangnan Dietaryʼ groups: Q2 vs. Q1 [odds ratio (OR) = 0.356, 95% confidence interval (CI) = 0.202–0.629]; Q3 vs. Q1 (OR = 0.457, 95% CI = 0.262–0.797). Relative influence factors for muscle mass loss were age (>65 vs. <45, OR = 2.027, 95% CI = 1.117–3.680), physical activity (OR = 0.550, 95% CI = 0.315–0.960), income (high vs. low, OR = 0.413, 95% CI = 0.210 –0.810), sex (female vs. male, OR = 0.379, 95% CI = 0.235–0.519). Conclusions: After 3 years of follow‐up, participants' muscle mass declined significantly. The ʻJiangnan Dietaryʼ pattern prevented muscle mass loss and is recommended to the wider population.
