Background: This study aimed to compare the nutritional and bone health status between young men with mild-to-moderate intellectual disability and those without intellectual disability and to determine predictors for their bone health status. Method: A total of 95 men (47 men with intellectual disability; 48 men without intellectual disability), aged 20-39 years, participated in this study. Anthropometric profile, dietary intake, physical activity level and calcaneal speed of sound (SOS) were collected. Results: The men with intellectual disability had moderate diet quality whilst the men without intellectual disability had poor diet quality. More participants with intellectual disability (97.9%) were inactive compared with their counterparts (10.4%). The SOS value was similar between groups and was lower than the reference. Increasing age and low physical activity level were negative predictors for bone health status. Conclusion: Both young men with and without intellectual disability have suboptimal nutritional and bone health status. Strategies to improve their nutritional and bone health status are warranted.
