From: Gender and socioeconomic disparities in BMI trajectories in the Seychelles: a cohort analysis based on serial population-based surveys

  Men

Current smoking -1.46 P < 0.001 -2.17 P = 0.001
High SES (vs. low) 1.58 P = 0.003 -1.79 P = 0.011
Age (10 years) 0.55 P = 0.073 2.55 P < 0.001
Age^2 (10 years) -0.18 P = 0.145 -0.69 P < 0.001
Cohort (10 years) 0.52 P = 0.050 1.82 P < 0.001
Age * high SES 1.61 P = 0.004 0.08 P = 0.908
