Table 6. Comparison of averages of vitamin D levels, according to solar exposure.

Stages	Low (1)	Mild (2)	Appropriate (3)	F value	p value
	(n=204)	(n=59)	(n=68)
2	24.5	-	29.3	0.971	0.415
3A	24.6	24.9	31.1	2.190	0.124
3B	21.0	27.5	34.6	2.476	0.000
4	20.7	23.2	29.4	9.764	0.000
5	14.5	22.0	21.5	2.039	0.156

There are statistically significant differences in the averages of vitamin D levels and the solar exhibition for the 3b and 4 stages
