If Australians increased their level of vigorous physical activity each week, what changes in health status would result? (A) Increased life expectancy and decreased incidence of breast cancer (B) Decreased life expectancy and decreased incidence of colon cancer (C) Increased life expectancy and increased prevalence of cardiovascular disease (D) Decreased life expectancy and decreased prevalence of cardiovascular disease - HSC - SSCE Personal Development and Physical Education - Question 9 - 2007 - Paper 1

Increasing physical activity generally leads to a higher life expectancy, contradicting this option. While physical activity can lower the incidence of colon cancer, the assertion of decreased life expectancy makes this option incorrect.

This option is inconsistent with research findings. An increase in physical activity is associated with lower rates of cardiovascular diseases, not increased prevalence. Thus, this option is incorrect.

This option is inaccurate as increasing physical activity is typically associated with increased life expectancy, not a decrease. Furthermore, it generally reduces the prevalence of cardiovascular disease.
