Object of this study was the occupational stress of 336 teachers (276 women and 60 men) with stable or temporary employment in schools of Pescara, town of Central Italy. The levels of anxiety were determined by STAI and STAI II, those of job strain", "job insecurity" and social support by the Karasek's questionnaire, and the perception of subjective symptoms by a 12 item test. There were no significant differences depending on the type of school. The women with temporary contract showed higher levels of "job insecurity", while the men with temporary job showed also higher values of STAI I and STAI II. The scores of anxiety of the women were positively correlated with "job strain", "job insecurity" and perception of subjective symptoms and negatively with social support, while the only correlations of STAI I and STAI II of men showing statistical significance of men was that with "job insecurity. Job strain was negatively correlated with the perception of symptoms both in women and men. These results evidence differences in the occupational stress of men and women; in particular, job insecurity may enhance anxiety in men.

77 men working in a university were investigated. Trait and state anxiety were determined by STAI I and STAI II; job strain (job demand/decision latitude), social support and job insecurity were analysed by a 46 item Karasek's questionnaire and subjective symptoms by a 12 item test. The employees of a library (mean age 49 years), in contact with students, showed significantly higher values of job strain, STAI I, STAI II and subjective symptoms than a control group of employees with similar age. Young employees and sanitary staff with temporary employment showed higher level of job insecurity than control subjects with stable position. Blood cytotoxic activity (reported in another study) was significantly lower in the old employees with job strain or in the young employees with job insecurity (but not in the sanitary staff) than in the controls; this demonstrates that not only occupational stress but also job insecurity may play an important role in affecting the health status.

Accidents in building sites led us to study risk perception in workers employed in this field. We disposed of 300 workers, aged 18-65, who had to answer to a questionnaries were signing among seven risks the more present in their activity, chosing among five levels. So for each risk the worker had to quantify parameters such as: danger, frequence of accidents, actitude to risk-control, training on risk. The risk of falling from high sites has been perceived as extremely dangerous but it is possible to control it. Less dangerous is eyes exposition to chemical agents or dust. Manual movementation of weight and lacerations would be the most frequent source of accidents. Moreover would be insufficient the capacity to control the rick related to Weight manual movementation and vibrations. Workers answered in questionnaries that risk training on vibration was not sufficient, on the contrary they knew the risk of falling from high site. So we conclude that to reduce accidents in building sites it is necessary make better training on field, modifying the individual behavior among workers.
