更快的进食速度与能量摄入增加有关，但对儿童进食速度，食物摄入量和肥胖之间的关系知之甚少。我们研究了吃得快的孩子是否消耗更多的能量，以及这是否与更高的体重状况和肥胖有关。我们假设进食速度介导儿童体重和随意能量摄入之间的关系。来自新加坡健康成长（GUSTO）队列的儿童（N=386）在4.5岁时参加了视频记录的随意午餐，以测量急性能量摄入。对三种进食行为（咬、咀嚼和吞咽）的视频进行编码，以获得进食速率（g/min）的测量值。测量体重指数（BMI）和肥胖的人体测量指标。一部分儿童（n=153）接受MRI扫描，以测量腹部皮下和内脏脂肪。高于/低于平均进食率的儿童被分为进食速度较慢和较快的儿童，并在身体成分测量中进行比较。进食率与能量摄入呈强正相关（r=0.61，p<0.001），进食率与儿童BMI状态呈线性正相关。进食速度快的儿童比进食速度慢的儿童多消耗75%的热量（Δ131 kcal，95%CI [107.6，154.4]，p<0.001），并且具有更高的全身（p<0.05）和皮下腹部肥胖（Δ118.3 cc; 95%CI [24.0，212.7]，p=0.014）。中介分析显示，进食率介导儿童体重与餐时能量摄入之间的联系（B=13.59，95% CI [7.48，21.83]）。吃得快的孩子有更高的能量摄入，这与BMIz增加和肥胖有关。
Faster eating rates are associated with increased energy intake, but less is known about the relationship between children’s eating rate, food intake and adiposity. We examined whether children who eat faster consume more energy and whether this is associated with higher weight status and adiposity. We hypothesized that eating rate mediates the relationship between child weight and ad libitum energy intake. Children (N=386) from the Growing Up in Singapore towards Healthy Outcomes (GUSTO) cohort participated in a video-recorded ad libitum lunch at 4.5 years to measure acute energy intake. Videos were coded for three eating-behaviours (bites, chews and swallows) to derive a measure of eating rate (g/min). Body mass index (BMI) and anthropometric indices of adiposity were measured. A subset of children underwent MRI scanning (n=153) to measure abdominal subcutaneous and visceral adiposity. Children above/below the median eating rate were categorised as slower and faster eaters, and compared across body composition measures. There was a strong positive relationship between eating rate and energy intake (r=0.61, p<0.001) and a positive linear relationship between eating rate and children’s BMI status. Faster eaters consumed 75% more calories than slower eating children (Δ131 kcal, 95%CI [107.6, 154.4], p<0.001), and had higher whole-body (p<0.05) and subcutaneous abdominal adiposity (Δ118.3 cc; 95%CI [24.0, 212.7], p=0.014). Mediation analysis showed that eating rate mediates the link between child weight and energy intake during a meal (b=13.59, 95% CI [7.48, 21.83]). Children who ate faster had higher energy intake, and this was associated with increased BMIz and adiposity.
