To investigate the determinants of dyslipidemia in preschoolers.
A total of 227 preschoolers residing in an urban area of the city of Diamantina, Minas Gerais, Brazil were evaluated at age 5 years, using a cross-sectional design. Dietary intake from a food frequency questionnaire, anthropometric/biochemical parameters, and socioeconomic/behavioral information from a questionnaire were evaluated. 'Mixed diet', 'snack', and 'unhealthy' dietary patterns were identified using principal component analysis. The determinants of dyslipidemia were examined using Poisson regression analysis.
The prevalence of dyslipidemia in this study was 65.19%. Preschoolers who less frequently consumed foods in the 'mixed diet' dietary pattern had a higher risk of high concentrations of low-density lipoprotein cholesterol (PR=2.30; p=0.004) when compared with those with more frequent consumption of the 'mixed diet' dietary pattern. Preschoolers whose mothers had lower levels of education presented a lower risk of high concentrations of low-density lipoprotein cholesterol (PR=0.43; p=0.003), and preschoolers who were overweight/obese presented with greater risk of high concentrations of low-density lipoprotein cholesterol (PR=2.23; p=0.003).
The determinants of dyslipidemia identified in this study were less frequent consumption of foods in the 'mixed diet' dietary pattern, higher body mass index, and lower level of maternal education. This study shows that despite the young age of the group under study, they already present a high prevalence of dyslipidemia, which is an important risk factor for cardiovascular disease.
探讨学龄前儿童血脂异常的决定因素。
本研究采用横断面设计,对巴西米纳斯吉拉斯州迪亚曼蒂纳市城区 227 名 5 岁学龄前儿童进行评估。通过食物频率问卷评估膳食摄入量、人体测量学/生化参数以及来自问卷的社会经济/行为信息。采用主成分分析识别“混合饮食”、“零食”和“不健康”的饮食模式。采用泊松回归分析检验血脂异常的决定因素。
本研究血脂异常的患病率为 65.19%。与经常食用“混合饮食”模式的儿童相比,较少食用“混合饮食”模式食物的儿童患高浓度低密度脂蛋白胆固醇的风险更高(PR=2.30;p=0.004)。母亲受教育程度较低的儿童患高浓度低密度脂蛋白胆固醇的风险较低(PR=0.43;p=0.003),而超重/肥胖的儿童患高浓度低密度脂蛋白胆固醇的风险更高(PR=2.23;p=0.003)。
本研究确定的血脂异常决定因素为较少食用“混合饮食”模式食物、较高的体重指数和较低的母亲受教育程度。本研究表明,尽管研究对象年龄较小,但他们已经存在高血脂血症的患病率,这是心血管疾病的一个重要危险因素。
