It is widely accepted that the growth of children is a general marker of the health of children in a community. Moreover, it is assumed that the secular changes are affected by environmental conditions such as inadequate nutrition and poverty. Increases in stature of school children living in Sendai diminished at the end of the 20th century, although they remained taller and heavier than those in the preceding years after World War II. Because there was a reacceleration in growth after a reduction in acceleration, further study is required to confirm whether these secular trends are changing or not.

運動後の手掌冷却がその後の持久的運動のパフォーマンスに及ぼす影響について明らかにすることを目的とした。運動習慣のある男子大学生10名(20〜22歳)を対象者とした。1回目の多段階漸増負荷試験後に,回復期に手掌冷却を実施した時としなかった時で,2回目の漸増負荷試験の結果と1回目との変化を比較した。手掌冷却はバケツにためた10〜15度の冷水に手を浸漬した。手掌冷却により回復安静期における鼓膜温は有意に低下した。これは冷却部の放熱量が大きくなり,冷やされた血液が身体の深部に戻ることで深部体温が下がったため,深部体温と相関のある鼓膜温が低下したと考えられた。また、手掌冷却により走行距離や最大酸素摂取量の有意な低減抑制が認められた。これは、深部体温の低下により,蓄熱容量が増大したためであると解された。最大酸素摂取量は中枢性疲労により低下する。手掌冷却により蓄熱容量が増大し,中枢性疲労が抑制されたため最大酸素摂取量の低減抑制が起きたと考えられた。運動後の手掌冷却はその後の持久的運動パフォーマンスの低減を抑制し,バケツにためた冷水に手掌を10分間浸漬する程度でも十分な効果が得られると示唆された。

High/low alcohol tolerance is determined by genetic polymorphisms of ADH2 and ALDH2. Currently, operators conduct ethanol patch testing for assessment of alcohol tolerance in a subjective manner; therefore, the test results may vary among individuals. The present study was designed to verify the reliability of ethanol patch testing, with a focus on changes in skin color due to seasons. Two operators were assigned to perform ethanol patch tests, and alcohol-related genetic polymorphisms were evaluated to verify the results.  The study included 129 healthy students from Utsunomiya University (age range: 21-24 years). These students were selected because they met the eligibility criteria for the study (all necessary information had to be available, i.e. results for all questionnaire items and patch tests, as well as genetic analysis). Alcohol-related genes tested in this study were ADH2 and ALDH2. During the ethanol patch tests, two operators examined the subjects' cutaneous reactions immediately after lint pad had been removed from their skin, and at 10 min after removal.  Ethanol patch test to the subjects was performed twice: once in summer and once in winter. We also administered a questionnaire to assess the students' views on alcohol and drinking habits. According to the cutaneous reactions examined at 10 min, there was significant concordance between the results of ethanol patch tests and ALDH2 genetic polymorphisms. The results of the patch tests performed by the 2 operators (A and B) in summer showed that the concordance rate between the operators was 93.8% (κ coefficient: 0.889; 95% confidence interval: 0.815-0.962, p<0.001) for the cutaneous reactions at 10 min after lint pad removal. Moreover, the same operator's data showed that the concordance rate between the results of the summer and winter patch tests was 70% or higher. These findings suggest that ethanol patch testing is a reliable assay of alcohol tolerance, although the results may be influenced by seasons and individual operator subjectivity. Therefore, during ethanol patch tests, it is important to take into account test conditions such as the time of year and skin color, and to evaluate the results comprehensively.

これまで内臓脂肪面積(VFA)と肥満関連遺伝子との関連性についての報告はない.今回は肥満関連遺伝子としてB3AR、B2ARやUCP1を用い、VFAの蓄積に及ぼす肥満関連遺伝子の影響について検討した.被験者は男性81名、女性186名である.測定項目はVFA、腹囲、血糖、血清脂質、血圧である.アンケートは生活習慣、食習慣及び運動習慣である.3遺伝子の多型別にVFAを比較した結果、有意差は認められなかった.また、年齢、運動習慣、歩行量を調整した分析においても多型間に有意差は見られなかった.一方、男性においては運動習慣との間に有意差が確認され、運動の実施がVFAの減少に影響を及ぼすことが示唆された.

Objectives: The Boston Naming Test (BNT) has been used to assess the language development of children in many epidemiology studies, and its usefulness is confirmed. The BNT consists of 60 black and white line drawings of objects and animals. There are no normative data available for this test for Japanese children. The purpose of this study was to collect normative information in Japan and to examine the correlation between the score of the BNT and Intelligence Quotient (IQ) of the Wechsler Intelligence Scale for Children third edition (WISC-III). Methods: The BNT was translated into Japanese and administered in children registered to the birth cohort of the Tohoku Study of Child Development at the age of 84 months. The participants for analysis in this study were 449 children (237 boys, 212 girls). Results: There were four items with percentage scores below 1%; Igloo, Knocker, Muzzle, and Yoke. Many Japanese children could answer ‘abacus’ and ‘compass’, which are difficult for US children. Although the score of the BNT correlated with IQ of the WISC-III (p<0.001), as compared with the previous studies, the correlation coefficient was low. Conclusions: The BNT is quick and easy to use and valuable for researchers in evaluating language ability in children. Since the BNT was developed in the United States, the cultural values of that country are reflected in the BNT score. This implies that the BNT should be modified to fit Japanese population.

Being overweight is a major risk factor for development of lifestyle-related diseases, and the sheer volume of current evidence that childhood obesity persists into adolescence and adulthood suggests the importance of rectifying obesity in childhood. The present study followed up children in the 1st to 6th grades of elementary school to examine whether being overweight was a continuous trend. In addition, increases and decreases in the adiposity of the students were examined in order to clarify fluctuations in their physical build. The subjects of the study were 3991 students (2046 boys and 1945 girls) attending all 68 schools in city U who were tracked for 6 years. The students were divided into 10th percentiles based on their degree of overweight. Using the median 45-55th percentile as a reference group, univariate logistic analysis was used to calculate the odds ratio of students who were overweight in the 1st grade remaining so in the 6th grade. It became clear that students in the 85th percentile or higher in first grade were 39.8 times more likely for boys and 21.9 times more likely for girls to be overweight in the 6th grade than 1st grade students in the reference group. Boys and girls who were markedly overweight in the 1st grade continued to demonstrate high degrees of obesity in the 6th grade. About 80% of both boys and girls who were overweight in the 1st grade of elementary school continued to be overweight in the 6th grade. Based on the above findings, it is clear that the degree of overweight in the 1st grade of elementary school has a strong influence on the corresponding degree in the 2nd grade and thereafter, thus suggesting the importance of preventing overweight developing upon entry to elementary school.

Objectives: To evaluate child development, social competence, like intellectual ability, is an important aspect. The social competence of a child is prescribed by behaviors suitable for the society (adaptive behaviors) and behaviors not suitable for the society (maladaptive behaviors). The Vineland Adaptive Behavior Scales (VABS) have been widely administered to children in a semi-structural interview to evaluate social competence. The Social Competence test (S-M test) widely used in Japan is a translated version of the Vineland Social Maturity Scale for adaptive behaviors. Since only the region of adaptive behaviors was translated into Japanese, we attempted to develop a Maladaptive Behavior Scale in Japanese based on the VABS to evaluate the social competence of children. Methods: The Maladaptive Behavior Scale of the VABS was translated into Japanese and back-translated to ensure appropriate translation. It was administered to children belonging to the birth cohort of the Tohoku Study of Child Development at the age of 66 months. The subjects for analysis in this study were 451 children (230 boys, 221 girls). Results: To assess internal consistency, we used the standardized Cronbach alpha coefficient and the result was 0.81. The correlation coefficient between the scores of the S-M test and those of the Maladaptive Behavior Scale was −0.15. The correlation coefficient between the scores of the Child Behavior Checklist at 30 months and those of the Maladaptive Behavior Scale was 0.44. Conclusion: These results suggest that the Maladaptive Behavior Scale may be a reliable instrument for assessing maladaptive behavior in Japanese children.
