Trends in least square mean (±standard error) values for body mass index and waist circumference

Data were from 1998, 2001, 2005, and 2007 Korea National Health and Nutrition Examination Survey (K-NHANES) (10,043 men and 12,758 women aged 20+). Regression analyses were employed to estimate age-adjusted least square means (standard errors) of obesity measures and to test time trends of the means, after taking account of primary sampling units, stratification, and sample weights from the K-NHANES.
