Table 1 Change over time in the prevalence of risk factor exposure

From: An investigation of the apparent breast cancer epidemic in France: screening and incidence trends in birth cohorts

Age group HRT (RR = 1.17 [21]a) Alcohol (RR = 1.7 [24]b) Obesity (RR = 2.0 [24]c)
  1980-1990 1995-2005 1980-1990 1995-2005 1980-1990 1995 -2005
50-59 7.9% 31.6% 16.7% 13.5% 4.1% 6.4%
60-69 7.7% 30.7% 7.0% 5.7% 6.1% 10.4%
70-79 2.3% 9.0% 3.7% 3.0% 6.1% 10.4%
  1. a RR resulting from the four available models in table six of "AFSSAPS report"[21]. RR = Total of expected exposed cases (3922.15)/Total of expected non-exposed cases (3358.78) = 1.17
  2. Prevalence data restricted to population based samples: "ESPS-EPAS" and "3C" [21].
  3. b Interpolation between delivered results (1.5 and 2.0)
  4. c Prevalence in age group 60-69 was extrapolated to age group 70-79
