Abstract

Background

Parental weight status is a key predictor of childhood obesity. However, limited evidence exists on how longitudinal changes in parental BMI influence children's weight trajectories, particularly in families at elevated risk for type 2 diabetes.

Objectives

To investigate children's body mass index-for-age z-score (BMIz) changes over a 2-year period, associated with independent and cumulative changes in parents' BMI.

Methods

In the Feel4Diabetes study, data from 12 280 children (age: 8.2 ± 1.0 years) and their parents were analysed to assess changes in child BMI-for-age z-scores over 2 years in relation to parental BMI changes. Analyses were adjusted for study design and baseline socio-demographic factors and were conducted in both the total sample (all-families) and high-risk for type 2 diabetes families (HR-families).

Results

In the all-families dataset, a 1 kg/m² independent decrease in maternal and paternal BMI was associated with a −0.037 (−0.041, −0.033) and −0.027 (−0.031, −0.023) change in child's BMIz [mean (95% CI)]. The joint parental effect was stronger [−0.32 (−0.36, −0.28)], particularly in HR-families [−0.34 (−0.42, −0.26)].

Conclusions

Parental BMI reductions, especially when both parents are involved, contribute to favourable BMI changes in children. The changes were more pronounced in HR-families, underscoring the need for interventions targeting the whole family in populations at elevated risk for type 2 diabetes.

追踪亲子双体的BMI变化：来自Feel4Diabetes研究的见解。

背景：父母体重状况是儿童肥胖的关键预测因素。然而，关于父母体重指数的纵向变化如何影响儿童体重轨迹的证据有限，特别是在2型糖尿病风险较高的家庭中。目的：调查儿童体重指数-年龄z分数（BMI）在2年内的变化，与父母BMI的独立和累积变化相关。方法：在Feel4Diabetes研究中，分析了12280名儿童（年龄：8.2±1.0岁）及其父母的数据，以评估儿童BMI年龄z分数在2年内的变化与父母BMI变化的关系。根据研究设计和基线社会人口因素对分析进行调整，并在总样本（所有家庭）和2型糖尿病高危家庭（hr -家庭）中进行分析。结果：在所有家庭数据集中，母亲和父亲体重指数每下降1 kg/m2，儿童体重指数变化分别为-0.037（-0.041,-0.033）和-0.027(-0.031,-0.023)[平均值（95% CI）]。联合亲代效应更强[-0.32(-0.36,-0.28)]，特别是在hr家庭[-0.34(-0.42,-0.26)]。结论：父母BMI的降低，特别是当父母双方都参与时，有助于儿童BMI的良好变化。这种变化在hr家庭中更为明显，强调了针对2型糖尿病高危人群的整个家庭进行干预的必要性。

期刊介绍： Pediatric Obesity is a peer-reviewed, monthly journal devoted to research into obesity during childhood and adolescence. The topic is currently at the centre of intense interest in the scientific community, and is of increasing concern to health policy-makers and the public at large. Pediatric Obesity has established itself as the leading journal for high quality papers in this field, including, but not limited to, the following: Genetic, molecular, biochemical and physiological aspects of obesity – basic, applied and clinical studies relating to mechanisms of the development of obesity throughout the life course and the consequent effects of obesity on health outcomes Metabolic consequences of child and adolescent obesity Epidemiological and population-based studies of child and adolescent overweight and obesity Measurement and diagnostic issues in assessing child and adolescent adiposity, physical activity and nutrition Clinical management of children and adolescents with obesity including studies of treatment and prevention Co-morbidities linked to child and adolescent obesity – mechanisms, assessment, and treatment Life-cycle factors eg familial, intrauterine and developmental aspects of child and adolescent obesity Nutrition security and the "double burden" of obesity and malnutrition Health promotion strategies around the issues of obesity, nutrition and physical activity in children and adolescents Community and public health measures to prevent overweight and obesity in children and adolescents.
