OBJECTIVE
: To analyze the associations between socioeconomic status (SES) indicators and physical activity and overweight/obesity in children.
METHODS
: 485 children wore accelerometers for 7 days. Variables included time in sedentary behavior and moderate-to-vigorous physical activity (MVPA), and steps/day. Children were further categorized as meeting or not meeting guidelines of ≥60min/day MVPA and ≥12,000 steps/day. Body mass index (BMI) and body fat percentage (BF%) were measured using bioelectrical impedance. Overweight/obesity was defined as BMI >+1 SD and BF% ≥85th percentile. Parents answered questionnaires that questioned total annual household income, parental education level, parental employment status and automobile ownership.
RESULTS
: Children averaged 59.5min/day in MVPA (44.1% met MVPA guidelines), and 9639 steps/day (18.4% met steps/day guidelines). 45.4% and 33% were overweight/obese classified by BMI and BF% respectively. Higher relative total annual household income level ( 0.31; 95% confidence interval=0.15-0.65), and relatively higher maternal (=0.38; 95%CI=0.20-0.72) and paternal (=0.36; 95%CI=0.17-0.75) education levels were associated with lower odds of children meeting MVPA guidelines. Household automobile ownership was associated with lower odds of children meeting MVPA (=0.48; 95%CI=0.31-0.75) and steps/day guidelines (=0.44; 95%CI=0.26-0.74).
CONCLUSIONS
: SES indicators were not associated with overweight/obesity, but higher SES was associated with lower odds of children meeting MVPA guidelines.
目的
分析社会经济地位（SES）指标与儿童身体活动及超重/肥胖之间的关联。
方法
485名儿童佩戴加速度计7天。变量包括久坐行为时间、中度至剧烈身体活动（MVPA）时间以及每日步数。儿童进一步被分类为是否达到每天MVPA≥60分钟和每日步数≥12,000步的指南标准。使用生物电阻抗测量体重指数（BMI）和体脂百分比（BF%）。超重/肥胖定义为BMI＞+1标准差且BF%≥第85百分位数。家长回答了关于家庭年总收入、父母教育水平、父母就业状况和汽车拥有情况的问卷。
结果
儿童平均每天MVPA为59.5分钟（44.1%达到MVPA指南标准），每日步数为9639步（18.4%达到每日步数指南标准）。分别按BMI和BF%分类，超重/肥胖儿童占45.4%和33%。相对较高的家庭年总收入水平（0.31；95%置信区间=0.15 - 0.65），以及相对较高的母亲（=0.38；95%置信区间=0.20 - 0.72）和父亲（=0.36；95%置信区间=0.17 - 0.75）教育水平与儿童达到MVPA指南标准的较低几率相关。家庭汽车拥有情况与儿童达到MVPA（=0.48；95%置信区间=0.31 - 0.75）和每日步数指南标准（=0.44；95%置信区间=0.26 - 0.74）的较低几率相关。
结论
SES指标与超重/肥胖无关，但较高的SES与儿童达到MVPA指南标准的较低几率相关。
