Abstract
Introduction: The latest data on prevalence of overweight (OW) and
obesity (OB) in the general Swiss resident population rely on the
Swiss Health Survey (SHS), a telephonic interview performed in 2007.
However, body mass index (BMI) is underestimated when self-reported,
leading to a misclassification of up to 60% of obese subjects. The last
survey with measured BMI performed in the 3 linguistic regions of
Switzerland dates back to 1977. We explored the regional prevalences
of OW and OB by measured BMI in the general Swiss resident
population.
Methods: Cross-sectional population-based survey in the 3 linguistic
regions of Switzerland in 2010-2011. Data on 1471 participants aged
15-95 years (712 men, 759 women) were available for the analysis. BMI
was calculated from measured height and weight and categorized into
3 groups according to WHO classification: lean (<25 kg/m2), overweight
(25-30 kg/m2) and obese (>= 30 kg/m2). Data on medication, smoking,
education, physical activity and dietary habitudes were collected using
a questionnaire.
Results: The overall prevalence of OW and OB was 32.1% and 13.9%,
respectively. OB prevalence was similar across the 3 linguistic regions
(13.5% in German-, 15.6% in French- and 12.0% in Italian-speaking
Switzerland, p = 0.40), unlike OW prevalence, which significantly
differed in unadjusted analyses (35.4%, 29.1% and 25.4%, respectively,
p = 0.005). In analyses including age, sex, smoking, physical activity
and education as covariates, living in the Italian-speaking region was
associated neither with BMI (linear regression) nor with OW or OB
(logistic regressions) . Age (beta coefficient [SE]: 0.064[0.006] kg/m2 per
year, p <0.001) and sex (-1.76 [0.23] kg/m2 in women, p <0.001) were
significantly associated with BMI.
Conclusions: Overweight and obesity affect nearly half of the Swiss
population aged >15 years. We observed no significant differences
across regions once we accounted for age, sex, education and lifestyle.
Public health interventions addressing modifiable behavioral factors to
reduce overweight and obesity in Switzerland can be expected to have
substantial benefits.
