Sedentary behavior has been associated with several cardiometabolic risk factors during childhood. However, little is known about the impact of sedentary behavior on the health and eating habits of physically active children and adolescents.
To evaluate the association between sedentary behavior and cardiometabolic risk factors and eating habits in physically active children and adolescents.
This cross-sectional study was conducted, including 516 physically active children and adolescents (10 to 18 years old; both sexes) enrolled in the social project "Estação Conhecimento-Vale" were evaluated. Biochemical and lifestyle variables (questionnaire) were collected. Sedentary behavior was determined indirectly (questionnaire), by using sitting time ≥ 3 hours per day as a cutoff point. A p-value < 0.05 was considered statistically significant for all tests.
Sedentary behavior was not associated with overweight/obesity (odds ratio = 0.72 [95% confidence interval (CI): 0.325-1.389]), hypertriglyceridemia (odds ratio = 0.63 [95% CI: 0.306-1.297]), low HDL cholesterol (odds ratio = 0.57 [95% CI: 0.323-1.019]), or high non-HDL cholesterol (odds ratio = 0.63 [95% CI: 0.283-1.389]). However, children and adolescents with sedentary behavior were more likely to regularly consume food in front of the television (odds ratio = 1.96 [95% CI: 1.114-3.456]) and to consume at least one ultra-processed food per day (odds ratio = 2.42 [95% CI: 1.381-4.241]). In addition, they were less likely to consume fruit regularly (odds ratio = 0.52 [95% CI: 0.278-0.967]).
There was no association between sedentary behavior and cardiometabolic risk factors in physically active children and adolescents. However, sedentary behavior was associated with inadequate eating habits. Thus, we may suggest that the regular engagement in physical activity may attenuate the deleterious effects of sedentary behavior on the cardiometabolic parameters of children and adolescents.
久坐行为与儿童时期的几种心血管代谢危险因素有关。然而，对于久坐行为对活跃的儿童和青少年的健康和饮食习惯的影响知之甚少。
评估久坐行为与心血管代谢危险因素和活跃的儿童和青少年饮食习惯之间的关联。
进行了这项横断面研究，评估了社会项目“Estação Conhecimento-Vale”中招募的 516 名活跃的儿童和青少年（10 至 18 岁；男女）。收集了生化和生活方式变量（问卷）。久坐行为通过间接（问卷）确定，将每天坐≥3 小时作为截断点。所有测试的 p 值<0.05 被认为具有统计学意义。
久坐行为与超重/肥胖（比值比=0.72[95%置信区间（CI）：0.325-1.389]）、高甘油三酯血症（比值比=0.63[95%CI：0.306-1.297]）、低高密度脂蛋白胆固醇（比值比=0.57[95%CI：0.323-1.019]）或高非高密度脂蛋白胆固醇（比值比=0.63[95%CI：0.283-1.389]）无关。然而，有久坐行为的儿童和青少年更有可能经常在电视机前进食（比值比=1.96[95%CI：1.114-3.456]）和每天至少食用一种超加工食品（比值比=2.42[95%CI：1.381-4.241]）。此外，他们定期食用水果的可能性较低（比值比=0.52[95%CI：0.278-0.967]）。
在活跃的儿童和青少年中，久坐行为与心血管代谢危险因素之间没有关联。然而，久坐行为与不良的饮食习惯有关。因此，我们可以建议，定期进行身体活动可能会减轻久坐行为对儿童和青少年心血管代谢参数的不良影响。
