Increasing proportions of Australians are overweight or obese, a problem sh
ared by all developed and, increasingly, developing nations. Now as many pe
ople in the world are overweight as underweight.
Increasing obesity is a serious public health as weft as economic problem.
Its associated greater risks of high blood pressure, heart disease, osteoar
thritis, type 2 diabetes, some cancers and other health problems consume co
nsiderable proportions of healthcare budgets.
Health inequalities often reflect social inequalities, but with overweight
there is also a male-female difference in the relationship between overweig
ht and socioeconomic status. Health promotion campaigns are underestimating
the social determinants of health, and "risk fatigue" is affecting attitud
es to complying with healthy lifestyle standards.
Proposals to reverse the obesity trend, such as taxing or restricting the a
dvertising of unhealthy foods, raise contentious issues of choice and regul
ation.
