A sample of 1003 children from grades one to six were recruited using convenient sampling.

The sample included 42.6% males and 57.4% females, with most attending public schools (65.3%) and 70.9% achieving excellent academic performance. Most fathers (79.3%) and mothers (94.9%) had higher education, and 37% of families reported a monthly income between 1,000 and 1,600 USD.

Significant factors associated with NE include being male (aOR: 1.6; 95% CI: 1.1-2.2), family history of NE (aOR: 6.1; 95% CI: 4.3-8.5), high fluid intake before bedtime (aOR: 1.6; 95% CI: 1.2-2.2), lower academic performance (aOR: 1.5; 95% CI: 1.1-2.1), daytime incontinence (aOR: 3.5; 95% CI: 1.4-8.5), and severe to extreme social anxiety (aOR: 7.4; 95% CI: 1.2-49.0).</p><p><strong>Conclusions: </strong>Considering the high prevalence of NE in the current study and its strong link with social anxiety, it underscores the need for integrated psychological support alongside medical management.
