Abstract:
Objective:To examine the influences of overweight and obesity on left ventricular hypertrophy (LVH) in school-aged children, and to provide the scientific reference for early screening and making interventional measures for the damage of their heart structure.
Methods:Based on a cross-sectional survey conducted in Jinan between 2012 and 2014, a total of 327 students aged 6-17 who had hypertension were selected. Covariance analysis and trend chi-square test were used to analyze the trend of left ventricular mass index (LVMI) and abnormal LVH rate across different categories of body mass index (BMI) after adjusted for age, gender and blood pressure (BP). Logistic regression analysis was used to evaluate the effects of overweight and obesity on LVH.
Results:After adjusting for age, gender and BP, covariance analysis indicated that with the increase of BMI, the levels of LVMI [(26.8±1.8, 34.7±1.5, 40.1±0.9)g/m2.7] and prevalence of LVH (80.%, 22.4%, 41.4%) showed upward trends (F/χ2=22.68, 24.28, P<0.05). Compared with normal weight school-aged children, the risk of LVH increased for overweight and obese school-aged children, and the odds ratios (95% confidence intervals) were 3.83 (1.16-12.61) and 9.18 (3.10-27.19), respectively.
Conclusion:Overweight and obesity significantly increase the risk of LVH in school-aged children. Effective prevention and treatment of overweight and obesity may reduce the risk of abnormal cardiac structure in school-aged children.
