Teacher:Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.
Teacher: Now, understand the problem? Solve this instance: Question: Do serum osmolarity and haematocrit modify the association between the impedance index ( Ht ( 2 ) /Z ) and total body water in the very old : the Newcastle 85+ study?
Answer: The association between the impedance index and TBW was not modified by hydration status, which may support the utilisation of leg-to-leg bioimpedance for the assessment of body composition in the very old.
