Body weight and height of Japanese boys and girls aged 12–14 years were measured to calculate the prevalence of obesity, leanness and anorexia nervosa. In boys, the prevalence of obesity as well as leanness was significantly higher in the areas where population density was lower and among the boys who attended schools with smaller numbers of pupils. In the girls, these findings were similar to the boys. On the other hand, anorexia nervosa was found in girls only more commonly in the areas with higher population density and in the larger schools. These results suggest that higher prevalence of obesity in certain subjects may be associated with increased numbers of leanness but not with anorexia nervosa.

“…Because it is not so easy to evaluate specifically volume of fat tissue (Ohzeki et al, 1992;Tsukuda et al, 1994), body weight and some indices for overweight (RollandCachera et al, 1982;Ohzeki et al, 1989Ohzeki et al, ,1990) are commonly applied to estimate body fatness instead of measurement of adipose volume. Serum leptin levels are influenced by age and=or sex predominantly, but not completely, through alteration in volume of fat tissue (Blum et al, 1997;Carlsson et al, 1997;Ahmed et al, 1999;Nakanishi et al, 1999).…”

Objective: To demonstrate sexual dimorphism in serum leptin levels not only during puberty, but also in childhood in Japan. Design: Cross-sectional study. Setting: Hamamatsu-Hokuen study in Japan. Subjects: Body weight and height were measured in normal-weight Japanese children and adolescents (143 boys, 178 girls), and 161 boys and 129 girls whose percentage of overweight for the standard (%Wt) was more than þ 25%. Serum leptin levels were compared with %Wt. Subjects were divided into group 1 (6 -10 y of age) and group 2 (11 -15 y of age) according to their age. Results: In overweight subjects, leptin was more highly correlated with %Wt in boys of group 2 (r ¼ 0.67, P < 0.0001) than group 1 (r ¼ 0.32, P ¼ 0.004). In girls as well, a correlation coefficient was greater in group 2 (r ¼ 0.67, P < 0.0001) than group 1 (r ¼ 0.44, P ¼ 0.0011). In normal-weight boys, there was no significant correlation between serum leptin and %Wt both in groups 1 and 2. On the contrary, statistical significance was demonstrated in the correlation between serum leptin and %Wt in group 1 (r ¼ 0.31, P ¼ 0.0019) and group 2 (r ¼ 0.35, P ¼ 0.0014) as well as in the total normal-weight girls (r ¼ 0.28, P ¼ 0.0011). Conclusions: It is suggested that sexual dimorphism is present in serum leptin levels, especially when compared to weight, as early as during childhood.

“…The index of excess weight (EW) was calculated using the following equation [3,8]: F.W(%) = (actual weight -standard weight) X 100/standard weight. The standard values for calculation of EW were based on a report by the Japanese Ministry of Education [7], The subjects with EW of2()%or m oreand-20% or less(67 boys and 64 girls) were excluded for determination of normal ranges because of the criteria for over-and underweight [3.…”

We measured body weight, height, and skinfold thickness (SFT) at ulnar, triceps, subscapular and suprailiac regions in 1,656 Japanese children aged 3-11 years. Means of SFT in boys and girls with normal weight exhibited similar changes with age to Caucasian children. However, nadirs of SFT were observed 1 year earlier and means at 11 years were slightly higher in Japanese. Correlation coefficients between SFT and excess weight (EW) were high in boys and girls when EW was more than 10 %. Some children with EW of more than 10 % had abnormal SFT. Skinfolds in all children with EW of 30% or more were beyond the normal limits. In this study, normal ranges of SFT in Japanese children are demonstrated and their racial characteristics are compared to Caucasians. It is suggested that children with EW of 10-30% are heterogenous and determination of fat volume is essential to confirm the diagnosis of obesity in these subjects.
