Figures & data

Table 1. Demographic characteristics information is shown.

	40–49	50–59	60–69	70–87
Age (years)	45.30 ± 2.77	55.43 ± 2.97	64.13 ± 2.73	75.18 ± 4.18
Height (cm)	165.40 ± 9.22	166.14 ± 6.02	164.77 ± 5.80	161.55 ± 7.41^b,c
Weight (kg)	69.09 ± 14.20	60.00 ± 10.36^a	59.51 ± 9.45^a	52.52 ± 9.27^a,b,c
BMI (kg/m^2)	25.27 ± 4.83	21.69 ± 3.42^a	21.95 ± 3.52^a	20.12 ± 3.27^a,b,c

Data are presented as average ± standard deviations.

^aValue was statistically significantly different from the 40 to 49 years group (p < .05).

^bValue was statistically significantly different from the 50 to 59 years group (p < .05).

^cValue was statistically significantly different from the 60 to 69 years group (p < .05).
