Abstract

Background/Aims: To project the numbers of pre-obese (BMI 25-29.99 kg/m²) and obese (BMI > 30 kg/m²) men and women aged 50+ in Germany until 2030 and to compare our estimates with actual figures from four European countries and the USA. Estimates are based on six scenarios encompassing improvements as well as worsenings of current trends. Methods: We used pooled data from 1999 to 2009 of the German Microcensus (n = 1,472,547). Using multinomial logistic regression models we estimated age-specific probabilities of pre-obesity and obesity and applied them to the 12th population projection of the Federal Statistical Office. Results: We project overall increases in absolute numbers of pre-obesity ranging between 14.2 and 18.2 million. However, the prevalence of pre-obesity is likely to decrease slightly. In contrast, absolute and relative numbers of obesity are projected to increase, ranging between 7.2 and 15.8 million. The international comparison revealed that pre-obesity prevalences will remain among the highest in Germany, while obesity is projected to fall below current levels of the UK or the USA. Conclusion: Pre-obesity and, particularly, obesity are likely to become a more prominent health issue in Germany in the near future which could have large repercussions for the public health system.
