Insights

Attention deficit hyperactivity disorder (ADHD) is linked to a high prevalence of nocturnal enuresis (NE) in children. Risk factors include male sex, low parental education, neonatal sepsis, family history of NE, low birth weight, and C-section delivery.

Area of Science:

  • Pediatrics
  • Child Psychiatry
  • Urology

Background:

  • Attention deficit hyperactivity disorder (ADHD) negatively impacts the resolution of incontinence.
  • Limited research exists on nocturnal enuresis (NE) risk factors in children with ADHD.

Purpose of the Study:

  • To determine the prevalence of NE in children diagnosed with ADHD.
  • To identify specific risk factors associated with NE in this population.

Main Methods:

  • A cohort of 331 children aged 6-10 years with ADHD was studied.
  • ADHD diagnoses were confirmed using DSM-IV-TR criteria.
  • NE was defined as nighttime wetting (with or without daytime wetting) occurring at least twice weekly for 3+ months in children aged 5+ without anatomical abnormalities.

Main Results:

  • The inattentional subtype of ADHD showed the highest NE prevalence (77.5%).
  • Significant risk factors for NE included a history of familial enuresis, cesarean delivery, and neonatal sepsis.
  • Lower birth weight and lower parental education levels were also associated with increased NE rates.

Conclusions:

  • Children with ADHD exhibit a high prevalence of NE.
  • Identified risk factors for NE in ADHD children include male sex, low parental education, neonatal sepsis, familial history of NE, low birth weight, and cesarean delivery.
  • The inattentional ADHD subtype is particularly associated with NE.

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Relative Risk01:12

Relative Risk

Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Intrinsically Disordered Proteins02:18

Intrinsically Disordered Proteins

Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Transcription Factors02:16

Transcription Factors

Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
