The short answer is yes, you should control for age. You can get the intuition as to why this might be important by graphing mean HAZ by age-in-months. A linear adjustment may be insufficient.
The slightly longer answer is - it depends on the identifying variation in your regression as to whether or not it will matter much. I'm attaching an unpublished working paper that may or may not be relevant, but discusses one context in which the problem can come up.
