Insights
Children with primary monosymptomatic enuresis nocturna (PMNE) have significantly lower vitamin D levels. Vitamin D deficiency is a key factor associated with childhood bedwetting, suggesting routine testing and supplementation may be beneficial.
Area of Science:
- Pediatrics
- Endocrinology
- Nutritional Science
Background:
- Primary monosymptomatic enuresis nocturna (PMNE) is a common pediatric condition.
- The role of vitamin D in PMNE is not fully understood.
- Vitamin D deficiency is prevalent globally, particularly in children.
Purpose of the Study:
- To investigate the association between vitamin D deficiency and PMNE in children.
- To identify risk factors for PMNE.
- To explore the correlation between vitamin D levels and enuresis frequency.
Main Methods:
- Retrospective case-control study involving 307 PMNE patients and 254 healthy controls (aged 5-18).
- Serum 25(OH)D3 levels measured via chemiluminescence immunoassay.
- Statistical analyses included Mann-Whitney U, Chi-square, Pearson correlation, and logistic regression.
Main Results:
- PMNE patients exhibited significantly lower serum 25(OH)D3 levels compared to controls (p < 0.001).
- Vitamin D deficiency was more common in the PMNE group.
- Vitamin D deficiency (OR: 3.164) and family history of enuresis (OR: 2.790) were independent risk factors for PMNE.
- A significant negative correlation was observed between vitamin D levels and weekly bedwetting frequency (r = -0.377, p < 0.001).
Conclusions:
- Children with PMNE demonstrate significantly lower serum 25(OH)D3 levels.
- Vitamin D deficiency is an independent associated factor for PMNE.
- Routine vitamin D level evaluation and investigation into supplementation benefits for children with PMNE are recommended.
Abstract:
Objective: The aim of this study was to investigate the relationship between primary monosymptomatic enuresis nocturna (PMNE) and vitamin D deficiency in children. Patients and Methods: This retrospective case-control study included 307 PMNE patients aged 5-18 years and 254 age- and sex-matched healthy control subjects. Demographic data and biochemical parameters of the participants were obtained from hospital records. Serum 25(OH)D3 levels were measured using the chemiluminescence immunoassay method. The Mann-Whitney U test, Chi-square test, Pearson correlation and multivariate logistic regression analysis were used for statistical analyses. Results: Serum 25(OH)D3 levels were significantly lower in the PMNE group compared to the control group (p < 0.001). The rate of vitamin D deficiency was higher in the PMNE group. Vitamin D deficiency (OR: 3.164, 95% CI: 1.195-8.378, p = 0.02) and family history of enuresis (OR: 2.790, 95% CI: 1.01-5.8, p = 0.04) were found to be independent associated factors for PMNE. A significant negative correlation was found between serum vitamin D level and weekly bedwetting frequency (r = -0.377, p < 0.001). Conclusions: Serum 25(OH)D3 levels were significantly lower in the PMNE group (p < 0.001, Cohen's d = 0.89). It is recommended that vitamin D levels should be routinely evaluated in children with PMNE and the potential benefits of vitamin D supplementation should be investigated in prospective studies.
