Association between underweight, serum albumin levels, and height loss in the Japanese male population: a retrospective study

Table 4 Association between serum albumin and height loss

	Serum albumin				P for trend	1 SD increment of serum albumin
	Quartile 1 (low)	Quartile 2	Quartile 3	Quartile 4 (high)	P for trend	1 SD increment of serum albumin
No. of participants	1,642	2,216	2,259	1,979
No. of height loss, n (%)	520 (31.7)	590 (26.6)	522 (23.1)	392 (19.8)
Age-adjusted model	Reference	0.82 (0.71, 0.94)	0.70 (0.61, 0.81)	0.62 (0.53, 0.72)	< 0.001	0.83 (0.79, 0.88)
Multivariable model	Reference	0.83 (0.72, 0.96)	0.72 (0.62, 0.83)	0.63 (0.54, 0.74)	< 0.001	0.84 (0.80, 0.88)

Multivariable model: Adjusted for age, underweight, overweight, obesity, hypertension, daily drinker, non-drinker, smoker, higher HbA1c, high HbA1c, dyslipidemia. SD standard deviation. 1 SD is 0.28 g/dL. Serum albumin levels: < 4.2 g/dL for quartile 1 (low), 4.2–4.3 g/dL for quartile 2, 4.4–4.5 g/dL for quartile 3, and ≥ 4.6 g/dL for quartile 4 (high)
