在患有先天性心脏病的儿童和青少年中，评估儿童和青少年体育活动问卷（PAQ-C）和青少年体育活动问卷（PAQ-A）的标准效度、内部一致性、信度和临界点。儿童和青少年先天性心脏病是一种特殊的高心血管风险人群，其体育活动尚未得到广泛评估。我们纳入来自加拿大BC儿童医院的84名参与者（13.6±2.9岁，50%为女性），患有单纯（37%）、中度（31%）或重度先天性心脏病（27%）以及心脏移植接受者（6%）。他们完成了PAQ-C（≤11年，n = 28）或a(≥12年，n = 56)，并在右臀部佩戴三轴加速度计（GT3X+或GT9X） 7天（n = 59符合有效磨损时间标准）。每日中至剧烈体力活动的中位数为每天46.9分钟（IQR为31.6-61.8），25%的人符合体力活动指南的定义，即每天≥60分钟的中至剧烈体力活动。paq评分中位数为2.6 （IQR为1.9-3.0）。paq评分与身体活动的加速度测量指标（rho = 0.44-0.55，均p<0.01）和久坐行为（rho = -0.53, p<0.001）显著相关。内部一致性高（α = 0.837）， 4个月期间PAQ-Scores的可靠性（稳定性）也高（ICC = 0.73, 95%CI 0.55-0.84; p<0.001）。在PAQ-C和paq - a联合样本中，我们发现PAQ-Score临界值为2.87区分了符合物理指南和不符合物理指南的样本（曲线下面积= 0.80 (95%CI 0.67-0.92)）。PAQ在儿童和青少年冠心病患者中的效度和信度与先前在健康儿童中的研究相当或更强。因此，PAQ可用于估计患有冠心病的儿童和青少年的一般体力活动水平。
To assess the criterion validity, internal consistency, reliability and cut-point for the Physical Activity Questionnaire for Children (PAQ-C) and Adolescents (PAQ-A) in children and adolescents with congenital heart disease–a special population at high cardiovascular risk in whom physical activity has not been extensively evaluated. We included 84 participants (13.6±2.9 yrs, 50% female) with simple (37%), moderate (31%), or severe congenital heart disease (27%), as well as cardiac transplant recipients (6%), from BC Children’s Hospital, Canada. They completed the PAQ-C (≤11yrs, n = 28) or–A (≥12yrs, n = 56), and also wore a triaxial accelerometer (GT3X+ or GT9X) over the right hip for 7 days (n = 59 met valid wear time criteria). Median daily moderate-to-vigorous physical activity was 46.9 minutes per day (IQR 31.6–61.8) and 25% met physical activity guidelines defined as ≥60 minutes of moderate-to-vigorous physical activity per day. Median PAQ-score was 2.6 (IQR 1.9–3.0). PAQ-Scores were significantly related to accelerometry-derived metrics of physical activity (rho = 0.44–0.55, all p<0.01) and sedentary behaviour (rho = -0.53, p<0.001). Internal consistency was high (α = 0.837), as was reliability (stability) of PAQ-Scores over a 4-months period (ICC = 0.73, 95%CI 0.55–0.84; p<0.001). We identified that a PAQ-Score cut-point of 2.87 discriminates between those meeting physical guidelines and those that do not in the combined PAQ-C and–A samples (area under the curve = 0.80 (95%CI 0.67–0.92). Validity and reliability of the PAQ in children and adolescents with CHD was comparable to or stronger than previous studies in healthy children. Therefore, the PAQ may be used to estimate general levels of physical activity in children and adolescents with CHD.
