Study population

The study will be conducted in two parts: (1) Pilot part: approximately 30 participants who have a physician diagnosis of nocturia. Participants will be recruited by one clinical site in the US. (2) Main part: a sample of 10,000 participants who are representative of the general population in the US stratified by age (≥30), gender, and race. Participants will be recruited by e-mail from a web-based panel of people that have previously opted in to be contacted for research studies.

Inclusion criteria

  • At least 30 years of age;
  • Willing to provide ;
  • Able to read US-English or Spanish
  • Able to use a computer and access the internet.

Exclusion criteria

Exclusion Criteria:

  • Symptomatic acute urinary tract infection (UTI) (experiencing symptoms such as pain or burning when you urinate, strong and frequent urge to urinate, or cloudy, bloody, or strong-smelling urine);
  • Currently pregnant or ≤12 months postpartum;
  • Recent surgery in the last \<6 months;
  • Current lifestyle that leads to irregular or atypical circadian patterns (e.g. employed in overnight shift work)
  • Prior YouGov survey participation in past two weeks
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Groups and cohorts

  • Pilot Part

    After providing consent, participants with nocturia will complete web-based baseline EpiNP survey followed by 3-day bladder diary and then a qualitative interview.

    Diagnostic Test: Testing of EpiNP baseline survey, bladder diary and a qualitative interview · Other: No other intervention

  • Main Part

    After providing consent, participants will complete web-based baseline EpiNP survey. All respondents who report greater than equal to (≥)2 voids/night, and a randomly selected cohort of respondents reporting 0 and 1 void/night will use the EpiNP 3-day web-based bladder diary.

    Diagnostic Test: Baseline EpiNP survey · Diagnostic Test: Bladder diary · Other: No other intervention

Interventions

  • Diagnostic testBaseline EpiNP survey

    The survey takes approximately 20 to 30 minutes to complete, and consists of the following: Short Form Health Survey version 2.0 (SF-12v2.0); Lower Urinary Tract Symptoms (LUTS) Tool; Patient Perception of Bladder Condition (PPBC); Self-report Medical History and Current Medication Form; Nocturia Impact Diary (NID); Disease-Specific Healthcare-Seeking Behavior and Treatment; Epworth Sleepiness Questionnaire (ESS); Patient Reported Outcome Measurement Information System Fatigue-Short Form version 1.0 (PROMIS F-SFv1.0); Patient Health Questionnaire (PHQ-8); Work Productivity and Activity Index (WPAI-SHP); Sexual health questions; lifestyle and sociodemographic questions; additionally, only men will complete the International Prostate Symptom Score (IPSS).

  • Diagnostic testBladder diary

    It consists of four components: measurement of waist and neck circumference, daily voiding diary (to assess voiding patterns, including frequency, volume, associated urgency, and incontinence episodes over a 24-hour period), NID (to assess nocturia impact), and assessment of morning sleepiness for 3 consecutive days and nights (including the morning of the fourth day).

  • Diagnostic testTesting of EpiNP baseline survey, bladder diary and a qualitative interview

    This part briefly reviews the usability of the EpiNP survey and bladder diary. The feedback obtained after qualitative interview will be used to refine and finalize the instructions sent to the participants in the main part.

What researchers measure

Primary outcomes

  1. Prevalence of nocturia due to NP, NP with overactive bladder (OAB), NP with benign prostatic hyperplasia (BPH), and NP with BPH/OAB

    Nocturia due to NP will be derived using data of participants who completed the 3-day bladder diaries. Nocturnal polyuria was defined when nocturnal urine production proportional to daytime urine production was greater than threshold 0.33 (Nocturnal Polyuria index \[NPi\]). Prevalence will be calculated using number of participants with nocturia due to NP, in the numerator (overall and by relevant strata \[e.g., by age/race/gender categories\]), with publicly-available estimates of the US population in the denominator (overall and for relevant strata). In addition, the prevalence of NP with OAB, NP with BPH, and NP with BPH/OAB will also be estimated.

    Time frame: Between July 2019 and June 2020

  2. To describe and compare demographic and clinical characteristics in participants with nocturia due to NP, NP with OAB, NP with BPH, and NP with BPH/OAB

    Time frame: Between July 2019 and June 2020

  3. To describe and compare burden of illness in participants with nocturia due to NP, NP with OAB, NP with BPH, and NP with BPH/OAB

    The burden measures (including health-related quality of life \[HRQL\], work productivity, fatigue, sleep, and depression as assessed through EpiNP survey and bladder diary) in participants with nocturia due to NP, NP with OAB, NP with BPH, and NP with BPH/OAB (overall and by relevant strata \[e.g., by age/race/gender categories\]) will be presented.

    Time frame: Between July 2019 and June 2020

Secondary outcomes

  1. Prevalence of nocturia due to NP across the subgroups of respondents

    Before using 3-day bladder diary in main part, the responders of the baseline EpiNP survey were stratified by three subgroups: all respondents who report ≥2 voids/night, randomly selected cohort of respondents reporting 0 and 1 void/night. Prevalence will be calculated using number of participants with nocturia due to NP across the subgroups of respondents, in the numerator, with publicly-available estimates of the US population in the denominator.

    Time frame: Between July 2019 and June 2020

  2. To describe and compare demographic and clinical characteristics in participants with nocturia due to NP across the subgroups of respondents

    Time frame: Between July 2019 and June 2020

  3. To describe and compare burden of illness in participants with nocturia due to NP across the subgroups of respondents

    Before using 3-day bladder diary in main part, the responders of the baseline EpiNP survey were stratified by three subgroups: all respondents who report ≥2 voids/night, randomly selected cohort of respondents reporting 0 and 1 void/night. The burden measures will be compared across the subgroups of respondents who self- report either 0 or 1 void/night with those reporting ≥2 voids/night.

    Time frame: Between July 2019 and June 2020
