Background: Infrequent voiding is two or lower than two micturitions per day and has not any organic causes; the etiology of this condition has not been found correctly; based on this, we evaluated developmental factors as a probable etiology for infrequent voiding. Methods: In the present study, we enrolled 200 children six to seven years of age (100 cases with infrequent voiding and 100 healthy ones). Height and weight were measured, compatible with gender and age, and related information, including personal and social development, problem-solving, fine motor, gross motor, communication, and defining words, were obtained by the Nelson development table and ages and stages questionnaires. Results: Based on personal-social (P = 0.009), problem-solving (P = 0.006), communication (P = 0.008), and language development (P = 0.006), there are statistically significant differences. However, fine motor (P = 0.557) and gross motor (P = 0.607) do not differ statistically. On the other hand, in terms of growth indices, in the evaluation of girls' height (P = 0.001), boys' height (P = 0.012), girls' weight (P = 0.014), and boys' weight (P = 0.016), there is a statistically significant difference between two groups. Conclusions: Based on the measured odds ratio, children with infrequent voiding have a higher risk of developmental disorders; developmental disorders can also increase the prevalence of infrequent voiding.
