Thin ideal preferences appear to be established between 5-6 years
By 3 years old children learn negative stereotypes about
overweight individuals (Latner & Schwartz, 2005)
This bias appears to intensify during teenage
years, then possibly diminish slightly
In boys, attributing negative characteristics to larger figures and
positive characteristics to thinner figures were associated with
fathers having more negative attitudes towards obese persons.
In girls, attributing positive characteristics to thinner figures was
only associated with greater maternal dietary restraint.
The Biology of Energy Storage
Energy storage is biologically adaptive
Differences between males and
females in energy storage needs.
Main Health Risks of Obesity
Cardiovascular disease
Diabetes
Sleep apnea
Osteo-arthritis
Gall bladder stones
Cancer of the colon
Fat Distribution Patterns And Health Risks
Gluteal-femoral obesity (hip and thigh) (typical
female pattern of fat deposition)
Relatively low health risk
Abdominal (visceral) obesity (typical male pattern of fat deposition)
Associated with hypertriglyceridemia, low high density
cholesterol and high low density cholesterol levels.
Associated with an insulin resistant state (pre-diabetic)
Associated with raised blood pressure.
Waist Circumference as a Measure of
Increased Health Risk
Waist circumference can give an indication of fat
located the abdominal region (and associated
with greater risk of diabetes, CHD etc);
ForCaucasians: Overweight:
Men >94 cm; Women >80 cm
Obese: men >102 cm; Women >
88cm Limited use in obesity
Consequences: Economic
Australia 2008- Total $58.2 billion, Direct costs $8.2
billion, Indirect costs (lost wellbeing/ “burden of
disease”) $49.9 billion
