Nathan Goodyear on 16 Sep 14Observational study finds BMI increase of 0.375 in both men and women per year. The waist circumference also increased by 0.37% per year in women compared to 0.27% in men. There was a significant reduction in physical activity over the same time period. In women, the reporting of physical inactivity increased to 52% FROM 19% compared to 44% FROM 11% in men. The authors found no association with change in calories. However, an assessment in quality of calories would have likely shown a glaring difference. Clear causation can not be concluded due to the fact that the study was observational.
