BMI group	Number of workers	Value (mean ± SD)				Value of health locus of control (mean ± SD)
BMI group	Number of workers	Age (years)	SOC (score)	Stress (score)	GHQ-12 (score)	SHLC (score)	IHLC (score)	CHLC (score)	FHLC (score)	PHLC (score)
No increase	89	52.3 ± 2.69	128.4 ± 16.1	28.2 ± 4.47	1.28 ± 1.10	11.5 ± 4.68	24.5 ± 3.30	14.8 ± 4.76	21.3 ± 3.95	19.0 ± 4.23
