中国における妊婦の過度の体重増加予防を目的とする社会的ネットワークの有効性の検証

本年度我继续进行了探索中国孕妇控制妊娠期体重增加潜在障碍的质性研究：1）将收集的数据汇总为英文科学数据; 2）使用photovoice进行了参与式行动研究，以探索潜在的干预工具（健康板块和教育）1）总结工作“无法控制妊娠期体重增加：中国孕妇的定性分析》成功发表在BMJ Open上。2）15名参与者被单独邀请到微信群，其中包括两名医务人员。向他们发放了健康牌和教育材料（指哈佛大学健康牌）。最后，受访者接受访谈，了解他们使用该车牌的感受和经验。采访表明，盘子是有用的摄入量，可以很好地提醒平衡饮食。此外，图文并茂的教材对家庭成员也有正面的影响。然而，他们中的大多数人表示他们不习惯使用盘子（例如，与普通碗相比太重，与其他人一起吃饭时不方便，担心盘子的质量）。许多其他研究（西方国家）显示食物盘子是有用的。然而，它可能是文化不兼容的中国设置。在进一步的研究中，相关的教育材料（健康板）有望成为一种有效的干预策略。健康板的插图被认为比交付真实的板更具成本效益。

This year I continued the qualitative study on the exploration of potential barriers of controlling gestational weight gain among pregnant Chinese women: 1) summarized the collecting data to English scientific data; 2) conducted a participatory action research using photovoice to explore potential intervention tools (Health Plate and education)1) The summarized work “Inability to control gestational weight gain: a qualitative analysis of pregnant Chinese women” was successfully published on BMJ Open.2) 15 participants were invited to a WeChat group individually including two medical staffs. They were delivered a Health Plate and education materials (referred to Harvard University Health Plate). Finally, they were interviewed on their feelings and experiences on using the plate. The interview showed that the plate is useful on intakes and can be a good reminder of balance diet. In addition, the education material with plenty illustrations also positively influenced their family members. However, most of them said they were not used to using the plate (e.g. too heavy compared to the normal bowl, not convenient when eat with other people, be anxious for the quality of plate).The food plate is showed to be useful in many other studies (western countries). However, it may be culturally incompatible in Chinese setting. Related education material (Health Plate) is expected to be an effective intervention strategy in further research. The illustration of Health Plate is considered to be more cost-effectiveness than delivering a real plate.
