25 The response rate was 81% over all in 199525 and gradually dropped to 56% in 2011.26 Analyses were performed across four distinct time points (1995, 1998, 2003 and 2010/2011). 2010 and 2011 were combined due to the smaller sample size in the more recent SHeSs. Analyses were restricted to adults aged 16�C65 who were economically active to allow the comparison between SEP indicators (highest education, occupational class and income). Non-respondents, refused and armed forces are excluded from the study, given that these numbers include unemployed and unemployed are more likely to belong to lower SEP groups and have a higher prevalence of obesity,27 28 the results may be prone to underestimation of overall obesity prevalence rates and for those at lower SEP. In this study, total missing value  including unemployed for occupational social class is only 6.7% within the study sample. These are population based surveys over 16-year period with large sample sizes, the effect of excluding unemployed makes minimal impact, therefore study results are deemed robust. Other socioeconomic indicators also have missing value are education (2.6%) and income (13.8%). Body mass index (BMI) is not available in 12.3% of study population. The final sample includes 27?059 men and women, a total 18.5% sample reduction.  Details of missing value are included in online S1-supplementary table 1. Data handling Obesity Height (m) and weight (kg) were measured by trained technicians. BMI was calculated by dividing weight in kilograms by height in metres squared. Obesity was defined as a BMI��30?kg/m2.29 Socioeconomic position We used three indicators of SEP: education level, occupational social class and household income. Participants education levels were grouped into three levels: (1) Limited/standard grade (grouped together due to small sample size in limited education group)��for those who finished education at age 16 or under; (2) Higher/advanced higher��for those who finished  education at age 17 or 18; and (3) Tertiary��for those who finished education at 19 or over. Occupational social class was categorised by [http://www.selleckchem.com/products/Romidepsin-FK228.html selleck inhibitor] Registrar General's Social Class.30 Owing to unequal sample size, the participants were then collapsed into four groups of roughly comparable size: (1) Semiskilled or unskilled manual; (2) Skilled manual; (3) Skilled non-manual; and (4) Professional or managerial. Household income was recorded on the continuous scale from which it was also divided into time point-specific quartiles. To examine the combined power of the three SEP markers, we developed a composite SEP score. Like previously,11 31 the composite SEP score was calculated by adding up scores from all three SEP markers (each of them have four groups, coded from 0 to 3).
