Strengths
  Considers the biological mechanisms through which shiftwork affects health.
Weaknesses
  Created using data from females only. Some variables in the JEM are highly dependent on personal behaviours (poor diet, lack of physical activity, lack of vitamin D). Some occupational codes included in the JEM contain very small numbers.
