Association between serum albumin levels and height loss in Japanese workers: a retrospective study

Table 2 Odds ratios (OR) and 95% confidence intervals (CI) for height loss in relation to albumin level

	Albumin tertile levels			p	1-SD increment of albumin
	T1 (Low)	T2 (Middle)	T3 (High)	p	1-SD increment of albumin
Men
No. of participants	1869	1712	1423
No. of participants with height loss (percentage)	525 (28.1)	415 (24.2)	310 (21.8)
Age-adjusted ORs	Reference	0.91 (0.78, 1.06)	0.84 (0.72, 0.998)	0.043	0.92 (0.86, 0.98)
Multivariable ORs	Reference	0.91 (0.78, 1.06)	0.85 (0.72, 1.01)	0.052	0.92 (0.86, 0.98)
Women
No. of participants	716	957	960
No. of participants with height loss (percentage)	209 (29.2)	233 (24.3)	216 (22.5)
Age-adjusted ORs	Reference	0.80 (0.64, 1.00)	0.71 (0.57, 0.89)	0.003	0.86 (0.79, 0.94)
Multivariable ORs	Reference	0.81 (0.65, 1.02)	0.71 (0.57, 0.89)	0.003	0.86 (0.79, 0.95)

Multivariable ORs: further adjusted for age, drinking status, smoking status, high BMI, hypertension, diabetes, dyslipidemia, and chronic kidney disease. Height loss: the highest quartile of height loss per year. Albumin tertile levels for men were < 4.5 g/dL for T1 (low), 4.5–4.6 g/dL or T2 (middle), and ≥ 4.7 g/dL for T3 (High), and for women the corresponding values were < 4.4 g/dL, 4.4–4.5 g/dL, and ≥ 4.6 g/dL. The 1-standard deviation increment of albumin was 0.2 g/dL in both men and women
