Abstract

Background and Objectives

Research on the relationship between body mass index (BMI) and strain values in children and adolescents is limited. Our aim was to analyse the relationship between BMI and strain values of both ventricles and left atrium in children and adolescents.

Methods

Both ventricles and left atrial strain values were compared among different BMI categories in children and adolescents from a town in the South of Spain.

Results

Of the 198 subjects, aged 6–17 years, 53% were of normal weight, 26% were overweight and 21% had obesity. Lower absolute values of left ventricular global longitudinal strain (25.9 ± 2.0% vs. 26.9 ± 2.2%, p = 0.002) and right ventricular free wall longitudinal strain (29.5 ± 4.2% vs. 30.8 ± 4.5%, p = 0.04) were found in subjects with obesity and overweight versus subjects with normal weight. A lower right ventricular four-chamber longitudinal strain was also observed in males with obesity and overweight (24.8 ± 3.3% vs. 26.4 ± 3.6%, p = 0.03). Statistically significant negative correlations of BMI were found for all ventricular, but not atrial, strain values in univariate analysis. This association turned non-significant for right ventricular four-chamber longitudinal strain in multivariate analysis.

Conclusions

Utilizing this new strain software, children and adolescents with high BMI were associated with significantly lower values for left and right ventricular free wall longitudinal strain, without impact in left atrial strain.

肥胖对西班牙农村儿童和青少年纵向心室和心房应变的影响，通过一种新的应变软件进行评估

背景与目的关于儿童和青少年身体质量指数(BMI)与应变值之间关系的研究是有限的。我们的目的是分析BMI与儿童和青少年心室和左心房应变值之间的关系。方法对西班牙南部某城镇不同BMI类别儿童和青少年的心室和左心房应变值进行比较。结果198名6 ~ 17岁儿童中，53%体重正常，26%超重，21%肥胖。肥胖和超重组左心室总纵应变绝对值(25.9±2.0%比26.9±2.2%，p = 0.002)和右心室游离壁纵应变绝对值(29.5±4.2%比30.8±4.5%，p = 0.04)低于正常体重组。肥胖和超重男性也存在右下心室四室纵向应变(24.8±3.3% vs. 26.4±3.6%，p = 0.03)。在单变量分析中，BMI与所有心室应变值呈显著负相关，而心房应变值无显著负相关。在多变量分析中，这种关联在右心室四室纵向应变中不显著。结论使用该应变软件，高BMI的儿童和青少年左、右心室自由壁纵应变值显著降低，且对左心房应变无影响。

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.
