No; astronauts have a negative nitrogen balance.
What factors might lead to a positive nitrogen balance?
Yes
Anabolism creates positive nitrogen balance. That means sort of body building. Catabolism creates negative nitrogen balance. That means loss of proteins from your body.
Positive nitrogen balance
No, it is positive.
No, it is an example of positive nitrogen balance. This is because a pregnant women is in need of protein to allow growth of the child, and in order to build protein you need Nitrogen. Therefor pregnancy is considered positive nitrogen balance.
Positive nitrogen balance occurs when the total nitrogen excreted in the urine, feces and sweat is less than the total nitrogen ingested. Positive nitrogen balance must exist for new tissue to be synthesized. When dietary protein intake or total energy intake is inadequate to maintain tissues total nitrogen balance, negative nitrogen balance occurs and new tissue is unable to be synthesized.

Pregnant women
While growing.
Nitrogen status is positive in growing infants, children, adolescents, pregnant women, and people recovering from protein deficiency or illness.
