New research reveals night-time toilet trips are not a trivial problem
Glasgow – 2 September 2011 –
New data, presented at the International Continence Society (ICS) Congress, highlight the significant detrimental impact of nocturia on the quality of life of patients who suffer from this under-reported and often misunderstood condition.1
Nocturia – the medical term for the complaint of needing to wake one or more times to pass urine at night – is commonly trivialized and often thought of as being a natural and inevitable part of growing older. As such, many patients suffer in silence without discussing their problem with their clinician.
The new research1 involved 5,503 men and women, aged 30-79 years from the city of Boston. Quality of life, from both a mental and physical health perspective, was measured using the internationally recognized SF-12 questionnaire.
Results from the study reveal the extent to which nocturia is associated with a decrease in overall quality of life, comparable to other chronic conditions such as hypertension, diabetes and arthritis. Nocturia was associated with a significant decrease in quality of life indicators, including sleep disturbance, and both the physical and mental health component scores of the SF12 (p-value<0.05).1
The data also suggest that repeated night time trips to the toilet significantly increase the likelihood of patients experiencing depression, especially among younger men and women.1
“This data sheds light on the real impact nocturia can have on the mental well-being and overall quality of life of patients with this under-reported condition” explained Dr Varant Kupelian, New England Research Institutes. “It is important that healthcare professionals engage with their patients to understand if they are experiencing nocturia related sleep disruption, and to discuss how best to manage their condition” he continued.
Results of a separate study2 also presented at ICS showed that nocturia is a problem for shift workers who sleep through the day and work during the evening. The study, involving more than 1,000 men and women aged 18-65, suggests that an increase in the number of night shifts undertaken over the course of a week correlates to a higher prevalence of nocturia.
Investigators concluded the survey results warranted a deeper investigation into the extent to which nocturia is more of a problem in people working night shifts due to a disturbance in their circadian clock which results in a disruption of vasopressin (anti-diuretic hormone) production.
Whilst many other studies have focused on the impact of distributed sleep patterns, the authors believe this is the first time a possible relationship between changes in circadian rhythm due to night time work and nocturia have been examined.
This finding is especially relevant as an estimated 17% of the European workforce are thought to be shift workers.3
Nocturia is the complaint that an individual has to wake and pass urine one or more times at night. The condition is equally common in men and women,4 and although it increases with age, it affects a significant proportion of younger, as well as, older people.5 On average, up to around 20% of adults aged 40-59 years have ≥ two toilet visits per night,6, 7 this increases to around 35% in those over 60 years.5
Nocturia is the leading cause of sleep disruption in older adults.8 Sleep is crucial for well-being, health, vitality and essential biological rhythms;9 disrupted sleep impairs all of these and studies show that insufficient or disrupted sleep can lead to physical and mental problems including depression and mood alteration.10, 11 Indeed, poor sleep is associated with disrupted endocrine and immune functioning, reduced health, and increased mortality.12, 13, 14, 15
Nocturia is a treatable condition and people making repeated night-time visits to the toilet are urged to seek help. Nocturnal polyuria – the production of an abnormally large volume of urine during sleep – is present in the majority of patients with nocturia (60-80%).16, 17, 18, 19, 20, 21
