In this study, we examined applicability of existing equations to predicting the body surface area (BSA) of children, and newly developed prediction equations for the BSA of children. BSA of 87 children of both genders (7∼12 yr) was determined by the three-dimensional photonic image scanning (3DPS), which was used as reference. BSA predicted using existing equations yielded overestimation or underestimation and/or a systematic error with respect to the reference. BSA prediction equations for boys and girls were developed using height and body mass as independent variables for the validation group and cross-validated for another group. The standard errors of estimation of the prediction equations were 105 cm2 (0.9 %) for boys and 158 cm2(1.4 %) for girls. In the cross-validation group, there was no significant difference between the predicted and measured values without systematic errors. These findings indicate that existing equations cannot accurately predict BSA of children, and that the newly developed prediction equations are capable of predicting BSA of children with adequate accuracy.

Seasonality of nutrient intake was evaluated by 7-successive-day food consumption survey in the ordinary season (March) and the slack season (June) of fish catch among 13 married couples in a Solomon Islands society, who were engaged in traditional horticulture and fishing, together with time allocation study. Males' time spent in gardening and fishing was significantly shorter in June than in March (gardening: -48 min/d, and fishing: -43 min/d; P<0 .05, respectively), while there was no seasonal difference in females. On the other hand, males spent more time in hunting and marketing, and females in particular did more time in marketing (P<0.01). No significant difference in energy intake between March and June was observed for either sex. The protein intake was significantly lower in June than in March (males: -23.9 g/d, P<0.01; females: -12.0 g/d, P<0.05). The males' fat intake was significantly higher in June than in March (+14.8 g/d, P<0.05), thought not significantly in females. To compensate the smaller amount of fish catch in June, the villagers spent more time in hunting and marketing, and they took larger amounts of coconut and a kind of nut, which abounds with fat . This study thus suggested that changes in food obtaining activities and food intake patterns of the villagers played significant roles to cope with seasonal shortage of fish catch.
1 0 0 0 OA エネルギー消費量の変動要因に関する基礎的研究
エネルギー消費量を評価するヒューマンカロリメーターの分析精度を向上させ、食事によるエネルギー消費量の評価法を提案した。また、エネルギー消費量に対する身体組成の影響や食習慣・運動習慣の影響について明らかにした。さらに、身体活動の種類と強度が評価できる3次元加速度計を用いて、歩数が中高強度の身体活動量をかなり反映するが、歩・走行以外の身体活動も重要であること、1日の身体活動量に対する歩・走行以外の身体活動の相対的な寄与が職業間で異なっていることを明らかにした。
