Bedwetting 3X more likely with low vitamin D – June 2014

3X more likely for 5-7 year-old children to have NE if low vitamin D - 2014

Vitamin D has been recognized to contribute to various physiological processes. However, no study has investigated serum 25-hydroxyvitamin D [25(OH)D] concentrations in children with nocturnal enuresis (NE) in the English literature.

In the present study, serum 25(OH)D concentrations were measured in five- to seven-year-old children with NE and compared with those in non-enuretic children to investigate whether there was any relationship between 25(OH)D and NE as the first time in the literature.

Two hundred forty-seven five- to seven-year-old children were recruited from Taizhou, Zhejiang Province, China. Serum 25(OH)D concentrations were measured, and the structured questionnaire was administered to the parents of all children. Low 25(OH)D was defined as serum 25(OH)D concentrations below 20 ng/ml.

The prevalence of NE was 7.3% in the group of children with 25(OH)D concentrations that exceeded 20 ng/ml; this prevalence was much lower than the 17.5% observed in the group of children with 25(OH)D concentrations below 20 ng/ml (p<0.05). After adjusting for potential confounders, serum 25(OH)D (≥20 ng/ml) was significantly associated with NE and represented a protective factor against NE (OR = 0.31, 95%CI = 0.092, 1.0, P<0.05). A nonlinear relationship between 25(OH)D and NE was observed. The prevalence of NE decreased with increasing 25(OH)D concentrations above 19 ng/ml. Additionally, children exhibiting higher frequencies of bedwetting had lower 25(OH)D concentrations [5-7 times/week: 18.3±4.8; 2-4 times/week: 20.9±4.1; 0-1 times/week: 23.6±6.4 (ng/ml), P<0.05)].

CONCLUSIONS: Low 25(OH)D was associated with an increased risk of NE in children aged five to seven years.

44% of 7-15 yearold children cured by 1,000 IU daily for 2 months - RCT June 2018

Nocturnal enuresis is known to be a common urinary bladder complication in children. Recent studies have associated vitamin D and omega-3 insufficiency with nocturnal enuresis.

This was a 2-month randomized, placebo-controlled, double-blind trial to measure the effects of vitamin D, omega-3 supplements, and their combination on nocturnal enuresis among 7-15-year-old children.

Participants (180 children with nocturnal enuresis) were selected from children referred to the Pediatric ward of Imam Reza Clinic in Shiraz, Iran. Demographic information and anthropometric measures were taken. Fasting blood and urine samples were also collected, and serum vitamin D and urine prostaglandin E2 were measured before and after intervention. Enuretic children were randomly assigned to four groups: Group A, vitamin D (1000 IU/day); Group B, omega-3 (1000 mg/day); Group C, both omega-3 (1000 mg/day) and vitamin D (1000 IU/day); and Group D, placebo.

The results suggested that the study groups were not significantly different regarding demographic and anthropometric measures at baseline. Comparison of different groups revealed that 44.4% of participants in Group A, 28.2% of Group B and 45% of Group C were cured from enuresis (P = 0.03). Serum 25(OH) D was significantly increased in Group A, but urine prostaglandin E2 was not significantly decreased in response to supplementation. Although supplementation with both Group A and Group B were found to be effective, the combined intervention did not increase the effect of each intervention solely.

The results showed that supplementation with vitamin D and omega-3 could reduce the number of wet nights among 7-15-year-old children with nocturnal enuresis.
