ヒトの生活において食事は重要な位置づけである。しかし、近年のライフスタイルの多様化に伴って食事の形態は変化し、「孤食」や栄養の偏った「偏食」がみられるようになった。そのような中で、「食育」が叫ばれてきている。食育の中でも食事の環境は大切であると考える。というのは、食事の環境は免疫機能の活性化を大きく左右し、加えて会食は、人間関係を形成するなど、社会的、精神的に良好な生活につながると考えられている。会食を行うことは、身体に必要な栄養素の摂取や心理面における満足感などの食事本来の目的のほかに、笑いや楽しみが得られ、ストレス軽減、免疫能の向上の効果があると考えられる。そこで、免疫系と内分泌系の機能検査として、末梢血中のNK細胞活性とコルチゾール値を用いて会食によるNK細胞活性、コルチゾール値の変化を検討し、会食がストレス軽減につながるかについて考察する。

Methods : Juveniles (1,364 students: 770 boys and 594 girls, aged 6–18 years) attending school in Hokkaido prefecture, Japan, were asked to complete a brief self-administered diet history questionnaire for 10-year-olds (BDHQ10y) providing information about personal history, lifestyle, and intake of nutritional elements. In addition, BMD and grip strength were measured. We analyzed the relationship between BMD and lifestyle factors. Results : The difference in BMD for boys was larger among the junior and senior high school groups. The difference in BMD for girls was larger among older elementary and later school children. Anthropometric variables and grip strength were strongly correlated with BMD. Having a nap-time routine was significantly correlated with BMD, but sleep time and sports club activities were not. BMD among juveniles who attained secondary sexual characteristics was significantly higher than that of juveniles of the same age who had not attained these characteristics. Calcium intake was significantly lower in senior high school students compared with other grades. Consumption of milk by senior high school boys and junior high school girls was weakly correlated with BMD. Conclusions : Our findings encourage educational interventions to counsel students to avoid weight loss and calcium deficiency. This effective intervention should begin before the higher elementary school, when juveniles have the greatest likelihood for preventing lower peak bone mass and osteoporosis.
