I have a data on obesity status of women in a country. This data is based on across sectional study. Now I want to find the determinants of obesity among the women. Here dependent variable is binary "obese=1/non-obese=0" based on BMI values. There are several co-variates like women age, education, occupational status, food habit, number of children, place of residence children etc. Can I use Structural Equation Model to find out the risk factors for obesity among women? or Logistic regression is the best option? Is there any other approach to do this?
Logistic regression is the classical method used for such situations. Medical journal reviewers as well readers are more familiar with this method. Logistic regression will clearly shows which factors are independently associated with obesity. Odds ratio can also be calculated using logistic regression which will give an idea of the size of effect quantitatively. Most existing studies also would also have used logistic regression so the results can be compared more easily.
Methods of Structural Equation Modelling are less well known, varied, with less clear assumptions, often difficult to interpret and generally more complex.
