The possible influence of diet and body weight on bowel habit in children is unknown. The present study aimed to investigate the inter-relationships between bowel function, excess body weight and dietary intake in a group of preadolescent children.
Eighty-four preadolescent children aged 7-10 years were recruited [mean (SD) age 9.7 (1.0) years]. All children completed a bowel habit diary, examining specific parameters of bowel function and a weighed food inventory concurrently for seven consecutive days. Height and weight measurements were also taken. Children were grouped according to whether they met dietary recommendations and by overweight status; differences in bowel function between the groups were then analysed.
Children who exceeded reference values for fat were more likely to report an incidence of straining to start (P = 0.005) and pain during defaecation (P = 0.021). Subjects who met protein recommendations were less likely to report incomplete evacuation (P = 0.000) and those who met zinc recommendations were less likely to report pain during defaecation (P = 0.044). Excess body weight (according to International Obesity Task Force cut-offs) was also associated with poor bowel habit, with overweight and obese children reporting lower defaecation frequency and a higher incidence of straining and feelings of incomplete evacuation, although these findings were not statistically significant. Defaecation frequency in healthy children was 1.4 defaecations per day compared to 1.2 defaecations for overweight and obese children.
A poor diet that fails to meet dietary recommendations as well as being overweight and obese appears to be associated with increased defaecation problems in preadolescent children.
饮食和体重对儿童肠道习惯的可能影响尚不清楚。本研究旨在调查一组青春期前儿童的肠道功能、超重和饮食摄入之间的相互关系。
招募了 84 名 7-10 岁的青春期前儿童（平均年龄 9.7±1.0 岁）。所有儿童均连续 7 天填写了肠道习惯日记，同时检查了肠道功能的特定参数和称重食物摄入量。还测量了身高和体重。根据儿童是否符合饮食建议和超重情况对其进行分组，然后分析各组之间肠道功能的差异。
脂肪摄入量超过参考值的儿童更有可能报告排便费力（P=0.005）和排便时疼痛（P=0.021）。符合蛋白质推荐摄入量的儿童更不可能报告不完全排空（P=0.000），而符合锌推荐摄入量的儿童更不可能报告排便时疼痛（P=0.044）。根据国际肥胖工作组的标准，超重也与肠道习惯不良有关，超重和肥胖儿童报告的排便频率较低，排便费力和感觉排空不完全的发生率较高，但这些发现没有统计学意义。健康儿童的排便频率为每天 1.4 次，而超重和肥胖儿童的排便频率为每天 1.2 次。
饮食不良，不能满足饮食建议，以及超重和肥胖，似乎与青春期前儿童排便问题增加有关。
