Prevalence of overweight, obesity and underweight and associated factors in a three-generation population-based study in a large Russian region
Authors' conclusion
Overweight/obesity prevalences among schoolchildren/adolescents were similar to mean global figures and higher than 15 years ago. Overweight/obesity prevalences in medium-aged adults (39.3% and 30.3%, respectively) and in old adults (41.5% and 18.7%, respectively) were higher than mean global figures. Associations of BMI-related parameters with other variables differed between the three generations. In old adults, higher BMI was related to metabolic syndrome but not with diabetes mellitus and hypertension.

Further findings
Factors associated with higher obesity prevalence in UEMS
- Younger age, female sex, Russian ethnicity, lower education, shorter height, less current smoking and alcohol, lower serum bilirubin and HDL, higher leukocyte count, more DM and metabolic syndrome, higher hypertension stage, more thoracic spine pain and CVD incl. stroke, higher intraocular pressure
Factors associated with higher obesity prevalence in UVOS
- Younger age, female sex, urban habitation, shorter height, less alcohol consumption, more metabolic syndrome
