This randomised controlled trial evaluated changes in parental self-efficacy and children's weight, after a Child-Centred Health Dialogue about preventing obesity.
We randomly assigned 37 Child Health Centres in Skåne county Sweden to provide usual care or the dialogue intervention. They included centres from high and low socioeconomic areas. The outcomes were changes in parental self-efficacy and any moderating effect on their children's body mass index 1 year later.
The baseline data were based on 1115 mothers and 869 fathers representing 1197 children (52% females) aged 4 years (3.9-4.2) with a standardised body mass index (zBMI) of 0.1 ± 0.9. The participation rates at follow-up, 1.1 ± 0.2 years after the intervention were 817 mothers and 508 fathers. Overall, parental self-efficacy had decreased by the 1-year follow-up. There was a significant intervention effect on maternal self-efficacy in promoting physical activity, however with unclear clinical relevance. Mothers' change in perceived self-efficacy in promoting a healthy diet seemed to moderate the intervention effect on zBMI change in children with zBMI > 0 with -0.01 (95% CI: -0.025 to -0.001; p = 0.03).
Our study suggested a possible link between increased maternal self-efficacy in promoting a healthy diet and a favourable development of zBMI.
本随机对照试验评估了以儿童为中心的健康对话预防肥胖后，父母自我效能感和儿童体重的变化。
我们随机分配瑞典斯科讷省的 37 个儿童健康中心提供常规护理或对话干预。它们包括来自高和低社会经济地区的中心。结局是父母自我效能感的变化及其对其子女 1 年后体重指数的任何调节作用。
基线数据基于 1115 名母亲和 869 名父亲，代表 1197 名年龄为 4 岁（3.9-4.2）的儿童（52%为女性），标准化体重指数（zBMI）为 0.1±0.9。干预后 1.1±0.2 年的随访参与率为 817 名母亲和 508 名父亲。总体而言，父母自我效能感在 1 年随访时下降。干预对促进体力活动的母亲自我效能感有显著影响，但临床意义不明确。母亲对促进健康饮食的感知自我效能感的变化似乎调节了 zBMI>0 的儿童的 zBMI 变化的干预效应，差值为-0.01（95%CI：-0.025 至-0.001；p=0.03）。
我们的研究表明，促进健康饮食的母亲自我效能感的增加与 zBMI 的有利发展之间可能存在联系。
