| Note: If the value of an adjusted risk ratio is more than 1, it represents how much more likely a person in that group is to become obese than a person in the reference group. For example, men aged 30 to 39 were 1.6 times more likely to become obese than men aged 50 to 56. If the adjusted risk ratio is less than 1, substract its value from 1 and multiply by 100%. This will give how much less likely is a person in that group is to become obese than a person in the reference group. For example, men in the middle-high income quintile were (1 - 0.60)*100% = 40% less likely to become obese than men in the lowest income quintile. The model also controls for wave length and wave length square. | ||||
