There was a highly significant association between sun exposure duration and vitamin D status ( p < 0.001).
Socioeconomic status showed a trend towards significance ( p = 0.08), with the highest deficiency observed in the upper socioeconomic class (71.4%), followed by middle (38.8%) and lower (31.4%) classes.
We planned exploratory trend interpretation when p approached significance (0.05–0.10) while emphasizing the risk of type I error.
