Incidence of some oral-based habits among college students and their correlations with use of oral stimulants.

This study explored the incidence of three personal habits and their correlates with popular tensional outlets. The 108 men and 202 women college students estimated how often they bit their fingernails, picked their noses, chewed on pencils or other objects, used specific tobacco products, used specific caffeine products, chewed gum, and exercised. Also, they rated their happiness on a seven-point scale in Likert format. The fingernail-biting incidence observed here was higher than was reported in previous samples of young adults, and more men than women were nail-biters. More men than women admitted to nose-picking; and about 61% of persons of either sex reported being occasional object-chewers. Men were more likely to exercise, use tobacco products, or consume iced tea than were women but were less likely to chew gum. The intercorrelations among the habits were not significant, and they were unrelated to lower self-reports of happiness. Both men and women who were object-chewers reported drinking greater amounts of cola beverages; otherwise, the relationships between these habits and product uses were not significant.
