Finally, sport factors were associated with SUM only in urban girls.
Girls and boys perform differently with respect to A-dep (−4.25±1.60, p=0.008), that is, depression, as characterised by A-dep, changed in relation to the earthquake and sport factors.
3 13 26 This investigation extends previous knowledge of associations between sport factors and SUM by emphasising the specific multivariate association of poor competitive achievement and long participation with a higher likelihood of smoking in urban girls.
5 The fact that an association between sport factors and alcohol consumption is found solely in urban girls is a logical reflection of the clear differences between urban and rural girls in regard to sports (rural girls participate in sports less frequently; see Results section).
After excluding two items with no sufficient factor loadings ("Feeling inferior to most people" and "Prefer to watch rather than take part in games and sports"), factor analysis was again conducted with the remaining 44 items on a hypothesized 6-factor structure.
Through a regional analysis of WR evolution during the Olympic era, this study underlines the positive or negative impact of historical (World Wars I and II, Cold War), political (Cultural Revolution), economical (Great Depression, Emergence of China) and sports factors (OG organisation, swimsuits introduced in 1999) on human performance.
Sports factors are specifically correlated with SUM for urban girls.
Sports factors included questions on the amount of time they have spent in sports (in years) and their most significant competitive achievements in sports.
Also, sports factors are characteristically related to SUM solely among urban girls, while the highest SUM is found in those girls who participate in sports for a prolonged period while being less successful.
Most of the existing studies focus on exercise through sports, individual factors, genetic factors, or occupational factors.
