3. Intro
 Long-term results of the treatment
of obesity are disappointing.
 Primary prevention is preferable
than treatment so as to decline the
incidence of obesity in the community.
 The influence of family history and
the age when body weight initially
increased are critical to identify those
people who are more susceptible to
become obese.

4. Methods
 955 Females
 Age: 39.8±12.7(M±SD), range: 18 - 78
 BMI: 35.11±6.57
All answered a questionnaire, if they had:
 Obese father (BMI>30)
 Obese mother (BMI>27)
 Obese brothers (BMI>27 for females and >30 for males)
 When body weight increased for the first time,
more than the 95th percentile for their age

10. Conclusions
 Females with strong family history of obesity
and mainly with obese mother, are in high risk
to become obese.
 Those cases are fatter
 The age of first appearance of obesity is
usually the childhood and adolescence.
 In those age groups and up to the 25th year
of life, prevention strategies must be applied.
