DESCRIPTION: Vincent Lorant and SILNE-R consortium\,	Institute of Health 
 and Society\, UCLouvain\, Belgium\n\nThe evolving social structure of ad
 olescent smokers: a longitudinal study in six European cities.\n\nAdoles
 cents’ friendship ties at school are key contributors to smoking behavio
 ur thanks to two properties: homophily and centrality.  Indeed\, in a fr
 iendship network\, smokers are more likely to be connected to each other
  (homophily) and also to be more central. Yet\, these two properties may
  have evolved over time\, under the increasing pressure of smoking denor
 malisation and under more stringent school tobacco control policies. We 
 tested two competing hypotheses with different policy implications: “saf
 ety in numbers” and “avoidance of stigma”. The “Safety in numbers” hypot
 hesis suggests that more stringent tobacco control policies lead to grea
 ter homophily among smokers\, as a social shield\; on the opposite\, acc
 ording to “stigma avoidance”\, smokers adapt to school tobacco control p
 olicies (STPs) by diversifying their social ties to avoid identification
  and more stringent enforcement of STPs. This study describes changes\, 
 at the school level\, in the social structure of smokers and non-smokers
  in 38 schools that participated in two waves of data collection\, in 20
 13 and 2016.
