The health benefits of regular physical activity are well documented. However, there are few studies associating this practice with sedentary behavior and cardiovascular risk in adolescents.
To evaluate physical activity levels and sedentary behavior and their associations with cardiovascular risk using the Pathobiological Determinants of Atherosclerosis in Youth (PDAY) score
A cross-sectional study carried out in state-owned public schools in Campina Grande, PB, Brazil, with 576 adolescents aged 15 to 19 years, investigating socioeconomic; demographic; lifestyle; and clinical variables. Data were collected using a validated form covering anthropometry data; blood pressure measurements; and laboratory tests. Data were analyzed using descriptive statistics, Pearson's chi-square test, and binomial logistic regression using SPSS 22.0 and adopting a 95% confidence interval.
Mean age was 16.8 years. The majority of the adolescents were female (66.8%); non-white (78.7%); and belonged to socioeconomic classes C, D and E (69.1%). The prevalence rates of sedentary behavior and physical inactivity were 78.1% and 60.2%, respectively. According to the PDAY score, 10.4% of adolescents were at high cardiovascular risk and 31.8% and 57.8% were at intermediate risk and low risk, respectively. PDAY scores were associated with sex and abdominal adiposity.
It was found that abdominal fat and being male were important cardiovascular risk factors in adolescents. Considering that modifiable risk factors were present, preventive measures aimed at lifestyle changes are essential.
定期进行体育活动对健康有益，这已得到充分证明。然而，很少有研究将这种做法与青少年的久坐行为和心血管风险联系起来。
使用青少年动脉粥样硬化病理生物学决定因素（PDAY）评分来评估身体活动水平、久坐行为及其与心血管风险的关联。
在巴西帕拉伊巴州坎皮纳格兰德的国有公立学校进行了一项横断面研究，研究对象为576名15至19岁的青少年，调查社会经济、人口统计学、生活方式和临床变量。使用经过验证的表格收集数据，内容包括人体测量数据、血压测量和实验室检查。使用SPSS 22.0进行描述性统计、Pearson卡方检验和二项逻辑回归分析，并采用95%置信区间。
平均年龄为16.8岁。大多数青少年为女性（66.8%）、非白人（78.7%），属于社会经济阶层C、D和E（69.1%）。久坐行为和身体不活动的患病率分别为78.1%和60.2%。根据PDAY评分，10.4%的青少年心血管风险高，31.8%和57.8%的青少年分别处于中度风险和低风险。PDAY评分与性别和腹部肥胖有关。
研究发现腹部脂肪和男性是青少年重要的心血管危险因素。鉴于存在可改变的危险因素，旨在改变生活方式的预防措施至关重要。
