摘要

背景：虽然心血管疾病（CVD）的临床症状通常在成年后才显现，但CVD病理在儿童时期就已经开始了。目的：研究青少年身体活动（PA）和膳食脂肪质量与动脉健康的关系。方法：共117名15 ~ 17岁青少年参与研究。评估久坐时间（ST）、轻度PA、中高强度PA （MVPA）、PA能量消耗（PAEE）、阻力训练量和膳食脂肪质量。采用阻抗心动图评估脉搏波速度（PWV）和心踝血管指数（CAVI），颈动脉超声检查颈动脉内膜-中膜厚度（cIMT）和颈动脉扩张性。结果：ST与cIMT呈负相关（标准化回归系数β = -0.225, p = 0.015）。MVPA和PAEE与PWV呈负相关（β = -0.245 ~ -0.228, p）。结论：MVPA和PAEE与动脉健康状况改善有关。此外，我们的研究结果表明，高PAEE有利于高SFA摄入量的青少年。

Associations of Physical Activity and Dietary Fat Quality With Arterial Health in Adolescents

Background

While the clinical signs of cardiovascular diseases (CVDs) are not usually visible until adulthood, the CVD pathology begins already in childhood.

Objectives

To study the associations of physical activity (PA) and dietary fat quality with arterial health among adolescents.

Methods

Altogether 117 adolescents 15–17 years of age participated in the study. Sedentary time (ST), light PA, moderate-to-vigorous PA (MVPA), PA energy expenditure (PAEE), resistance training volume and dietary fat quality were assessed. Pulse wave velocity (PWV) and cardio-ankle vascular index (CAVI) were assessed by impedance cardiography, and carotid artery intima-media thickness (cIMT) and carotid artery distensibility were assessed by carotid ultrasonography.

Results

ST was negatively associated with cIMT (standardised regression coefficient β = −0.225, p = 0.015). MVPA and PAEE were negatively associated with PWV (β = −0.245 to −0.228, p < 0.05) and CAVI (β = −0.226 to −0.212, p < 0.05), and positively with cIMT (β = 0.235 to 0.269, p < 0.05). MVPA was positively associated with carotid artery distensibility (β = 0.180, p = 0.047). Monounsaturated fat intake was positively associated with carotid artery distensibility (β = 0.190, p = 0.041). PAEE was negatively associated with CAVI in adolescents with higher saturated fat (SFA) intake (β = −0.367, p = 0.017), but not in adolescents with lower SFA intake (β = −0.095, p = 0.526).

Conclusion

MVPA and PAEE were related to better arterial health. Moreover, our results suggest that higher PAEE benefits adolescents with higher SFA intake.

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.
