電子監視は減塩に役立つ可能性がある(Abstract 16922)

電子監視機器の使用により減塩食への良好な適応が得られる
Successful adaptation to a lower sodium diet improves with use of an electronic monitoring device
電子監視機器の使用は心不全患者およびその家族が減塩食を遵守するのに役立つ可能性があるとの研究結果が2014年American Heart Association年次集会で発表された。Family Sodium Watcher Program（Family SWAP）では、減塩食の味付けに適応するための心不全患者と介護者／家族との協力関係に焦点を当て、食品内の塩分含有を検出する電子監視機器を使用し適応期間中には塩分の多い食事を避けた。患者－介護者のペア15組の3か月間トライアルにおいて、患者8人の介入群は、塩分摂取量を徐々に適応させる方法および電子監視機器を用いた12週間の心不全セルフケア教育を受けた。3か月後に、介入群では24時間の尿中ナトリウム排泄量が有意に減少した（患者3,894mg対3,604mg 、p=0.02；介護者4,123mg対3,380mg、p<0.05）。一部の人々は電子監視機器を用いることで減塩食がより楽しくなったと言い、90%の人々が食品中の塩分を味わう能力が変化した、と述べた。介護者らは、このプログラムによる負担の増加はなかった、と報告した。通常管理／コントロール群患者7人は、行動や塩分レベルに変化がなかった。

Using an electronic monitoring device may help heart failure patients and their families stick to a low-salt diet, according to research presented at the American Heart Association's Scientific Sessions 2014.

The Family Sodium Watcher Program (Family SWAP) focuses on a partnership between the heart failure patient and a caregiver/member of the family to adapt to the taste of a low-sodium diet and includes using an electronic monitoring device to detect salt content in food and avoid high-salt food during the adaptation period.
In the three-month trial of 15 patient-caregiver pairs, the intervention group of eight patients received 12 weeks of self-care education for heart failure with gradual adaptive strategies in salt intake and use of the electronic monitor. At three months, the intervention group had a significant reduction in 24 hour sodium secretion (Patients 3894mg vs. 3604mg, p=0.02; caregivers 4123mg vs. 3380mg, p<0.05).

Participants said the device was easy to use and helped them maintain a low-sodium diet. Some said they enjoyed their low-salt diets more and 90 percent noticed a change in their ability to taste salt in their food. Caregivers reported no increased burden due to the program.  The usual care/control group of seven patients didn't change behavior.

The study team members were Misook L Chung, Debra K Moser, and Terry A Lennie from the University of Kentucky in Lexington, Kentucky, USA.  They say that The Family SWAP may help the entire family improve their lifestyles.

The pilot study was funded by the American Heart Association and the University of Kentucky.
