BACKGROUND
Early research showed weight gain in children during the COVID-19 pandemic.
OBJECTIVE
To compare changes in BMI z-score of children with overweight and obesity in a personalised lifestyle intervention before and during the pandemic.
METHODS
Changes in BMI z-score half a year (T6) and twelve months (T12) after the first lockdown were included for 71 children in the '2020 during COVID' group and compared to 48 children in the '2019 before COVID' group, using a marginal model for repeated measures (model 1). Model 2 corrected for lifestyle intervention characteristics, and model 3 corrected additionally for family characteristics.
RESULTS
The mean difference in BMI z-score change was significantly different at T12 (+0.07 in 2020 versus -0.09 in 2019, = 0.022). Model 3 showed significant differences in BMI z-score change at both T6 (+0.15, = 0.024) and T12 (+0.18, = 0.016). This model also defined 'having a mother with obesity' (+0.13, = 0.019) and the frequency of no-show consultations (+0.41 per missed consultation per month, = 0.025) as related factors.
CONCLUSIONS
Lifestyle intervention in children with overweight and obesity is less successful in decreasing BMI z-score during the COVID-pandemic. Identified risk factors for less success could contribute to identifying children with higher risks for, and possibly prevent, BMI z-score increase.
背景
早期研究表明，在 COVID-19 大流行期间儿童体重增加。
目的
比较在大流行前后，对超重和肥胖儿童进行个性化生活方式干预前后 BMI z 分数的变化。
方法
将首次封锁后半年（T6）和一年（T12）的 BMI z 分数变化纳入“2020 年 COVID 期间”组的 71 名儿童和“2019 年 COVID 前”组的 48 名儿童，使用边缘模型进行重复测量（模型 1）。模型 2 校正了生活方式干预特征，模型 3 另外校正了家庭特征。
结果
T12 时 BMI z 分数变化的平均差异有统计学意义（2020 年为+0.07，2019 年为-0.09， = 0.022）。模型 3 显示 T6（+0.15， = 0.024）和 T12（+0.18， = 0.016）时 BMI z 分数变化均有显著差异。该模型还将“母亲肥胖”（+0.13， = 0.019）和错过咨询的频率（每月错过一次咨询增加 0.41， = 0.025）定义为相关因素。
结论
在 COVID-19 大流行期间，对超重和肥胖儿童进行的生活方式干预在降低 BMI z 分数方面效果较差。确定的低成功率的风险因素有助于识别 BMI z 分数升高风险较高的儿童，并可能预防 BMI z 分数升高。
