Abstract
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.

Plain language summary
Children and adolescents with obesity are at a high risk of being obese in adulthood. The aim of this study was to develop a multidisciplinary lifestyle intervention program targeted at children and adolescents with moderate to severe obesity. The study is based on the Intervention for Childhood and Adolescents Obesity via Activity and Nutrition (ICAAN) – quasi-experimental intervention trial - which recruited 103 participants aged between 6 and sixteen years (63 were boys and 40 girls). The study was based on 2 active treatment groups (usual care group vs exercise group) receiving a 16-week intervention program. Results indicate that children and adolescents with obesity can achieve positive effects on body composition, physical fitness, and cardiometabolic markers, particularly with the exercise intervention. Authors conclude that the moderate-intensity multidisciplinary lifestyle intervention program they developed, can be sustained in the real-world setting and it is applicable to both moderate and severe obesity.
Abstract
This study aimed to develop a multidisciplinary lifestyle intervention program targeted at children and adolescents with moderate to severe obesity, and assess the additional effects of exercise intervention when compared to usual care. Overall, the 103 enrolled participants were ≥85th percentile of age and sex-specific body mass index (BMI). Participants were divided into groups that received 16 weeks of either usual care or exercise intervention. The BMI z-score of the overall completers decreased by about 0.05 after the 16-week intervention (p = 0.02). After the intervention, only the exercise group had a significantly lower BMI z-score than the baseline score by about 0.1 (p = 0.03), but no significant group by time interaction effects were observed. At the 16-week follow-up, significant group by time interaction effects were observed in percentage body fat (%BF) (β = -1.52, 95%CI = -2.58⁻-0.45), lean body mass (LM) (β = 1.20, 95%CI = 0.12⁻2.29), diastolic blood pressure (β = -5.24, 95%CI = -9.66⁻-0.83), high-sensitivity C-reactive protein (β = -1.67, 95%CI = -2.77⁻-1.01), and wall sit test score (β = 50.74, 95%CI = 32.30⁻69.18). We developed a moderate-intensity intervention program that can be sustained in the real-world setting and is practically applicable to both moderate and severe obesity. After interventions, the exercise group had lower %BF and cardiometabolic risk markers, and higher LM and leg muscle strength compared to the usual care group.
