Higher motivation could support to lead behavioral change for obese children and adolescents. This study aimed to evaluate the effects of a nutrition care process (NCP)-based intervention targeted on diet and weight status in moderate to severe obese children and adolescents in Korea. One hundred four subjects (mean age: 10.95 years, body mass index (BMI) ≥97th percentile of age-sex) participated in the present study. Subjects were divided into a usual care group (UG) and a nutrition group (NG). All participants underwent nutrition education 6 times. The NG received individual access and continuous monitoring and setting goals with respect to nutritional problems. Consumption of high-calorie, low-nutrient (HCLN) food was significantly decreased (P < .05) and the Diet Quality Index-International (DQI-I) score also increased with respect to sodium (P < .001). The total self-efficacy score was increased from 9.15 to 10.14 points (P < .01). After 24 weeks, the BMI-z-score decreased from 2.27 to 2.19 in the NG (P < .05); however, no group difference was found. BMI-z-score was negatively associated with self-efficacy (β = -0.03, P < .019). NCP-based intervention might be helpful to solve dietary problems by enhancing self-efficacy and lower BMI-z-score in moderately to severely obese children and adolescents.

基于营养护理过程的 24 周干预可改善肥胖儿童和青少年的饮食质量、体重指数和动力

更高的动机可以支持领导肥胖儿童和青少年的行为改变。本研究旨在评估基于营养保健过程 (NCP) 的干预措施对韩国中度至重度肥胖儿童和青少年的饮食和体重状况的影响。一百四名受试者（平均年龄：10.95 岁，体重指数 (BMI) ≥ 年龄性别的第 97 个百分位）参与了本研究。受试者被分为常规护理组（UG）和营养组（NG）。所有参与者均接受了 6 次营养教育。NG 获得个人访问和持续监测，并就营养问题设定目标。高热量、低营养 (HCLN) 食物的消费显着减少 (P < . 05) 和饮食质量指数 - 国际 (DQI-I) 得分也增加（P < .001）。总自我效能感得分从 9.15 分增加到 10.14 分（P < .01）。24 周后，NG 组的 BMI-z 评分从 2.27 降至 2.19（P < .05）；然而，没有发现群体差异。BMI-z 分数与自我效能感呈负相关（β = -0.03，P < .019）。基于 NCP 的干预可能有助于通过提高中度至重度肥胖儿童和青少年的自我效能和降低 BMI-z 分数来解决饮食问题。BMI-z 分数与自我效能感呈负相关（β = -0.03，P < .019）。基于 NCP 的干预可能有助于通过提高中度至重度肥胖儿童和青少年的自我效能和降低 BMI-z 分数来解决饮食问题。BMI-z 分数与自我效能感呈负相关（β = -0.03，P < .019）。基于 NCP 的干预可能有助于通过提高中度至重度肥胖儿童和青少年的自我效能和降低 BMI-z 分数来解决饮食问题。
