| Summary: | External and internal factors, including body composition, active participation in physical activities, and adequate calcium intake (CI), have been suggested as important measures to optimize bone health, particularly among young adults, as peak bone mass accumulates during this stage of life. This cross-sectional study was conducted to investigate the relationship between body composition, physical activity levels (PAL), and CI with bone mineral density (BMD) in Malaysian university students. A total of 216 students from Universiti Kebangsaan Malaysia (72 each from Malay, Chinese, and Indian ethnicities) with a mean age of 22.1 ± 2.2 years were recruited. The assessment included body mass index (BMI), waist circumference (WC), body fat (BF), lean mass (LM), BMD, PAL, and CI. These were measured using a measuring tape, digital scale, quantitative ultrasound, the international physical activity questionnaire, and a 24-hr dietary recall alongside a food frequency questionnaire, respectively. The results showed that BMI, WC, BF, LM, BMD, PAL, and CI levels were 22.7 ± 4.5 kgm-2, 79.8 ± 12.3 cm, 23.2 ± 8.6%, 46.9 ± 11.4 kg, 0.29 ± 1.2, 2106.0 ± 1381.0 MET-min/week, and 335.4 ± 211.0 mg/day and 449.4 ± 284.6 mg/day, respectively. This means that the subjects had normal body composition, normal BMD levels, and moderate PAL. However, their calcium intake was generally low. The BMD mean of overweight subjects was significantly higher (f= 2.792, p=0.041) compared to the BMD of underweight subjects. A trend toward a significant increase of BMD (p=0.058) was also shown when PAL was increased. All parameters, except for body fats (r=-0.013, p=0.847) had a significantly weak correlation with BMD (r values: 0.143 to 0.198, p<0.05). The results of this study highlight the importance of maintaining body composition, living an active lifestyle, and optimizing CI levels for strong bones to prevent osteoporosis in old age. |
