Trends in principal cancer risk factors in Spain

Using data furnished by successive national health surveys, this article describes trends in the prevalence of smoking, physical inactivity, obesity, consumption of fruit and vegetables, and excessive alcohol consumption in Spain. For most of these factors, trends are shown since the end of the 1980s, and in the case of smoking, since the end of the 1970s. The findings indicate decreases in smoking--except among women aged 45-64 years--physical inactivity and high-risk alcohol consumption, and increases in consumption of fruit and vegetables, and obesity. The inclusion of these risk factors in cancer prevention strategies continues to be a matter of priority, in some cases because they display high prevalences despite their downward trend, as occurs with smoking among men and physical inactivity in the overall population, and in others because they display an upward trend, e.g. smoking among women aged 45-64 years and obesity in the overall population.
