Estilos de vida asociados con sobrepeso y obesidad en adultos españoles
2009
Objectives: To assess the relationship between life styles
and eating habits with the overweight and obesity prevalence
in a Spanish adult population.
Methods:A population-based, cross-sectional study conducted
on 2640 subjects older than 15 years, in Cadiz
(Spain). Surveys were conducted in subjects’ homes to
obtain life styles, eating habits, and anthropometric data.
Logistic regression has been used to study the association
between the life style variables and overweight and obesity.
Results: Prevalence of overweight and obesity in Cadiz
is 37% and 17%, respectively; higher in males and increases
with age. BMI has an inverse relationship with educational
level (PR = 2.3, 1.57-2.38). The highest levels of
obesity are associated with daily alcohol consumption
(PR = 1.39, 1.29-1.50), greater consumption of television,
and sedentary pursuit (PR 1.5, 1.07-1.24).
A lower prevalence of obesity is observed among those
with active physical activity (10.9% vs 21.6%), with differences
between sex. Following a slimming diet is more frequent
in the obese and in women but dedicate more hours
than men to passive activities. In men is greater the consumption
of alcohol, high energy foods and snacks.
Overweight and obesity is associated with the male sex
(OR = 3.35 2.75-4.07), high consumption of alcohol (OR =
1.38 1.03-1.86) and watching television (OR = 1.52 1.11-2.07),
and foods likes bread and cereals (OR = 1.47 1.13-1.91).
Exercise activities is a protective factor (OR = 0.76 0.63-0.98).
Conclusions: Life styles factors associated with overweight
and obesity present different patterns in men and
women and is necessary to understand them to identify
areas for behavioural intervention in overweight and
obesity patients.
