Effects of a behavioural approach on lifestyle habits in a healthy Italian population: a before-after interventional study.

Background: The study aimed to assess the effectiveness of an educational intervention promoting adherence to healthy diet and physical activity. Study design: Before-after interventional study. Methods: Participants were healthy volunteers, 18-70 y old, from Bologna. They followed a training course consisting of seven meetings and signed a contract to comply with the promoted habits, verified through questionnaires at the engagement phase (T0), three months later (T1) and one year later (T2). Results: One hundred, fifty-three subjects were involved, 75.8% were evaluated at T1 and 41.2% at T2. More than 80% of the subjects involved at T1 achieved an improvement of planned goals. Moreover, 77% of T1 compliants retained healthy eating and physical activity at T2. Conclusions: The proposed pathway of empowerment positively affected nutrition and promotion of physical activity at 3 months after the intervention (T1) and were maintained even after a year. The results appear to be promising for primary prevention across the spectrum of a healthy lifestyle educational approach.

[Behavior of blood gamma glutamyltransferase in workers exposed to hepatotoxic agents]. / Comportamento della gamma-GT sierica in alcune categorie di lavoratori esposti ad agenti epatotossici.

The behaviour of serum GT is evaluated as an indicator of exposure to enzymatic inductors that are potentially hepatotoxic. Serum GT was measured in 437 exposed workers and 149 controls. The statistically significant variation observed in the exposed group probably indicates enzymatic induction.

[Ocular fatigue syndrome in subjects exposed to video display terminals: definition and evaluation in a group of VDT operators]. / La sindroma da "affaticamento visivo" negli esposti a videoterminali: definizione e valutazione in un gruppo di operatori SIP.

The incidence of the "ocular fatigue syndrome" in a group of VDT telephone operators is evaluated and compared with a control group (people not working at VDT), by using questionnaires. The results show that the "ocular fatigue syndrome" is much more frequent in VDT operators in comparison with the control group.
