[Ergonomic and hygiene-associated aspects of work among supervision wardens].

Occupations associated with supervision involve various activities. Individuals employed in supervisory capacity may work as doorkeepers and receptionists, exit ticket inspectors, parking wardens or plant supervisors patrolling the area around the factory similarly to industrial guards. Supervision wardens are exposed to factors detrimental to human body. These negative factors include such phenomena as work in changeable climatic conditions, shift work, or a potential risk of injuries. The present authors emphasize the fact that the power expenditure at this kind of work is fairly low (314 kcal/8 h); however 75% of the examined persons suffer from overweight or obesity (BMI >30), and in many of these individuals, the cholesterol level is far above the reference range of 330 mg%. Eating habits of the majority of supervision wardens are derived from their previous occupational activity, e.g. as carpenters.
