In Italy, 42.5% of adult males is overweight and 10.5% obese, while 26.6% of the women is overweight and 9.1% obese. The economical consequences of a growing number of obese workers are relevant: obesity is associated to reduced participation to productive life, increased absenteeism, disability and need for health care, lower salaries, negative impact on productivity. The obese worker is characterized by reduced tolerance to effort, limited range of motion at spinal and joints level, reduced muscle strength normalized per body weight, lower tolerance to prolonged postures, reduced balance and overall reduced work capacity linear to the increase of body mass index. The present article reviews the most evident relationships between work factors (stress, musculoskeletal disorders, etc.) and obesity and speculates about possible interventions to prevent occupational issues for obese workers.

The psycho-social problems of a group of 365 Italian emigrants to Switzerland, admitted to psychiatric hospitals, were studied. It was found that non professional subjects (housewives, unemployed, retired) and manual workers (builders, waiters, factory workers) were more likely to suffer from psycho-social disorders. Only 11.1% of those studied had received a secondary education, therefore it could be assumed that subjects having a low technical and cultural level were less prepared, psychologically, for their new situation and were thus more susceptible to psycho-social disorders. The most frequent diagnoses were found to be: affective disorders, alcohol addiction, opiate addiction and schizophrenia. The study revealed that emigrants ran a greater risk of first time admittance to psychiatric wards whereas the local population had a greater number of relapses. In conclusion it is stressed that assistance with an aim to improve work, social and relationship conditions and to integrate the emigrants into their host society can reduce some forms of psycho-social disorders.

The relationship between alcohol and work was studied in a group of 260 voluntary patients (186 male and 74 female) admitted to the unit of Medicina del Lavoro, Pavia University for alcohol rehabilitation. The highest incidence of alcohol abuse was found in non-working subjects (pensioners, unemployed, housewives) although the start of excessive drinking takes place after beginning a working activity; a cause-effect relationship between these two factors can not be clearly determined, however. It is true that the stress provoked by this new condition (introduction to the work experience) can, in certain subjects, be a contributing factor in alcohol abuse. The increasingly lower age of initiation to alcohol reconfirms the need for prevention and instruction even at scholastic level.
