title: [Socio-demographic and life-style factors in a Swiss study of HIV non-progression].
abstract: OBJECTIVE
  The study investigates associations between socio-demographic or lifestyle factors and the progression of HIV.
  
  
  METHODS
  We recruited a Swiss cohort (n = 56) of long-term survivors and conducted a cross-sectional study of laboratory data as well as factors concerning socio-demography, life-style, and psychology. On the basis of laboratory results, the cohort was divided into 2 subgroups, non-progressors (n = 31) and slow progressors (n = 25), which were subsequently compared.
  
  
  RESULTS
  The comparison of socio-demographic factors showed that non-progressors were younger and had a higher income than slow progressors. Our data do not show an association between lifestyle and disease progression.
  
  
  CONCLUSIONS
  Younger age as a cofactor of non-progression confirms various other studies. The association between income and disease progression, also found in another cohort, cannot be explained by unequal access to therapies since, in accordance with the inclusion criteria, no one in our cohort had received antiretroviral therapies. Further research in this field seems important to determine possible links between socio-economic status and disease progression. The lack of association between disease progression and lifestyle factors such as drug use, physical activity or nutrition is in contrast to a common view of HIV in our study population, but is confirmed by a majority of the research in this field.
