An epidemiological study on the fraction ratio of serum .GAMMA.-GTP(1) and nutrient intakes with the difference of somatotype / 日本農村医学会雑誌

ABSTRACT

The purpose of the present paper is to explore the relationships between the activity and fraction ratio of serum γ-GTP and the dietary intake of nutrients through three groups (lean, normal and overweight) by Broca's index. Broca's index in each groups was under 89 for the lean group, from 90to 109 for the normal group and over 110 for the overweight group. The subjects of study were 249 young healthy men except alcoholic.<BR>Results of the survey were as follows<BR>1) There were statistically significant correlation between serum total γ-GTP activity in normal group and vitamin C intake (P<0.05).<BR>2) High negative correlations were observed between the fraction ratio of serum γ-GTP (1) and the vitamin B 1 intake (P<0.01), between the fraction ratio of serum γ-GTP (1) and vitamin C intake (P<0.01), and between the fraction ratio of serum γ-GTP (1) and the protein intake/kg of body weight (P<0.01) in the lean group. High negative correlations were observed between the fraction ratio of serum γ-GTP (1) and the protein intake (P<0.01), between the fraction ratio of serum y -GTP (1) and the vitamin B 1 intake (P<0.01), between the fraction ratio of serum γ-GTP (1) and vitamin C intake (P<0.01), and between the fraction ratio of serum γ-GTP (1) and the protein intake/kg of body weight (P<0.01) in the normal group. High negative correlation was observed between the fraction ratio of serum γ-GTP (1) and the vitamin C intake (P<0.01) in the overweight group.<BR>3) Multiple regression analysis showed that the variables which correlated best with the fraction ratio of serum γ-GTP (1) were dietary intakes of the energy, the vitamin C and the protein intake/kg of body weight in the lean group. The fraction ratio of serum γ-GTP (1) related to the vitamin C intake and the protein intake/kg of body weight in the normal group. In the overweight group, the fraction ratio of serum γ-GTP (1) related to the vitamin C intake and the animal protein intake.
