Regional inequalities in pre-pregnancy overweight and obesity in Sweden, 1992, 2000, and 2010

• Aims: To investigate regional differences and time trends in women's overweight and obesity in Sweden. Methods: Using data from the Swedish Medical Birth Register (women aged 18 years, first pregnancy only) and the Total Population Register accessed through the Umea SIMSAM Lab, age-standardized prevalence of pre-pregnancy overweight/obesity (BMI 25 kg/m(2)) and obesity (BMI 30 kg/m(2)) were estimated by county for the years 1992, 2000, and 2010. Maps were created using ArcMap v10.2.2 to display regional variations over time and logistic regression analyses were used to assess if the observed trends were significant. Results: The prevalence of pre-pregnancy overweight/obesity and obesity increased significantly in all Swedish counties between 1992, and 2010. In 2010, Sodermanland and Gotland exhibited the highest age-standardized overweight/obesity (39.7%) and obesity (15.1%) prevalence, respectively. The sharpest increases between 1992 and 2010 were observed in Vasterbotten for overweight/obesity (75% increase) and in Gotland for obesity (233% increase). Across the years, Stockholm had the lowest prevalence of overweight/obesity (26.3% in 2010) and obesity (7.3% in 2010) and one of the least steep increases in prevalence of both between 1992 and 2010. Conclusions: Substantial regional differences in pre-pregnancy overweight and obesity prevalence are apparent in Sweden. Further research should elucidate the mechanisms causing these differences.
