Is 174 pounds considered overweighted for a 13 year old girl?

Depends: Appropriate weight must factor in height.At 174 lb a 13 yo girl is in the heaviest 3% of girls her age. If she is average height for age, 5'2",she would be considered 74 lb above average weight with a body mass index of 32.4.(Obese) .If very tall,at 5'8"she would still be above expected weight and a BMI of 26.4.Desired BMI @ 13 is around 19.

Yes: Unless your daughter is extremely tall, say over 5ft 9 in, this weight woukd be considered heavy - it all depends on her height- check some height-weight tables to find out if she is above the 95th percentile, that would be the cutoff for the heavy, or overweight catagory
