PROBLEM TO BE SOLVED: To provide a health care device and a health care program capable of easily and accurately calculating a body fat amount.SOLUTION: The health care device 10 includes: a reference fat amount input unit 211 to which a reference fat amount Fo measured by a reference device to measure the fat amount of a subject is inputted a body weight input unit 212 to which the weight of the subject is inputted a memory unit 22 which at least memorizes the reference fat amount and the weight of the subject and a fat amount calculation unit 23 which calculates a body weight change amount ΔW that is a value obtained by subtracting the last weight Wb from the current weight Wn, obtains a fat change amount ΔF that is a value obtained by multiplying the body weight change amount ΔW by a prescribed coefficient k (0≤k≤1), adds the fat change amount ΔF to the reference fat amount Fo, and outputs the result value as a current fat amount Fn.COPYRIGHT: (C)2013,JPO&INPIT【課題】簡単かつ高精度に身体の脂肪量を演算することができる健康管理装置および健康管理プログラムを提供する。【解決手段】健康管理装置10は、被検者の脂肪量を測定する基準装置で計測された基準脂肪量Foが入力される基準脂肪量入力部211と、被検者の体重が入力される体重入力部212と、被検者の基準脂肪量および体重を少なくとも記憶する記憶部22と、今回の体重Wnから前回の体重Wbを差し引いた値を体重変化量ΔWとして算出し、当該体重変化量ΔWに所定の係数k(0≦k≦1)を掛けた値を脂肪変化量ΔFとし、基準脂肪量Foに脂肪変化量ΔFを加算して今回の脂肪量Fnとして出力する脂肪量演算部23と、を備える。【選択図】図2
