We examined the associations between late preterm (LPT) birth children aged ≥5 years and the frequency of bedwetting. Moreover, those who were born full-term/low birthweight (BW), LPT/low BW, LPT/normal BW and LPT/low BW were compared.
In total, we evaluated 614 patients who underwent assessments for frequent bedwetting at the three hospitals from January 2014 to December 2016. Data at the initial visit were collected from the electronic medical records. We assessed the patients' bladder diaries and questionnaires containing detailed information on demographics and frequency of bedwetting per month. Neonatal data were collected from the Maternal and Child Health Handbook.
Frequency of bedwetting in the LPT/low BW group was higher than in the term/low BW group (28 vs. 22.5, p < 0.05). However, the frequency between the LPT/normal BW group and the LPT/low BW group was not significantly different (28 vs. 28, p = 1.00). Multiple regression analyses were conducted to eliminate potential confounding factors, attention-deficit/hyperactivity disorder and intellectual disability, but results were not changed.
This study revealed that LPT/low BW was associated with increased frequency of bedwetting in children. The results suggest that gestational age should be considered when examining patients with severe bedwetting.
我们研究了≥5 岁的晚期早产儿（LPT）儿童与遗尿频率之间的关系。此外，还比较了足月/低出生体重（BW）、LPT/低 BW、LPT/正常 BW 和 LPT/低 BW 出生的儿童。
我们共评估了 2014 年 1 月至 2016 年 12 月期间在 3 家医院因频繁遗尿接受评估的 614 例患者。初始就诊时从电子病历中收集数据。我们评估了患者的膀胱日记和包含人口统计学和每月遗尿频率详细信息的问卷。新生儿数据从母婴健康手册中收集。
LPT/低 BW 组的遗尿频率高于足月/低 BW 组（28 比 22.5，p < 0.05）。然而，LPT/正常 BW 组和 LPT/低 BW 组之间的频率没有显著差异（28 比 28，p = 1.00）。进行了多变量回归分析以消除潜在的混杂因素，如注意力缺陷/多动障碍和智力残疾，但结果没有改变。
本研究表明，LPT/低 BW 与儿童遗尿频率增加有关。结果提示在检查严重遗尿症患者时应考虑胎龄。
