I feel like this question is very troll but my guess is for less weight to hold them down....
It takes 2 to 3 weeks depending how bad (1-2 weeks to heal up, 3 to go away completely )<span> you might need to see a doctor to get some Prednisone (a steroid to speed up your immune system and fight it off)

I believe the answer is: B. High self-esteem
Risk factor in this context refers to the things that might negatively influence the life of either the teen parents or the children.
Higher self esteem mean that the parents understand their own capabilities and defect and would not contribute to the negative effect.
