Roughly one in nine adults uses some form of incontinence product, though the share varies widely by age, sex, and health status. A nationwide survey found that about 11% of adults reported using pads, pull-ups, or diapers, with women using them at nearly three times the rate of men.1PubMed. Association between incontinence product use and quality of life in adult men: results from a nationwide survey The reasons stretch well beyond old age, encompassing childbirth recovery, cancer surgery, neurological disease, and even non-medical motivations that most people never hear about.
How Common Is Adult Incontinence
Urinary incontinence is far more widespread than casual conversation would suggest. Population studies across multiple countries put the prevalence of urinary incontinence somewhere between 25% and 45% of adults, though the range in individual studies stretches from about 5% to 70% depending on how the condition is defined and who is surveyed.2Springer Link. Continence Care Not everyone with leakage reaches for a diaper, of course. Many people manage with lifestyle changes, pelvic-floor exercises, or medications. Among older adults who do have incontinence, a large Chinese cross-sectional study found that about 31% used diapers.3PubMed Central. A large cross sectional study on diaper utilization and beneficial role in outdoor activity and emotions among incontinence elderly people
Fecal incontinence adds another layer. A U.S. population-based survey of more than 71,000 people found that about 14% reported some history of fecal incontinence, with a third of those experiencing episodes within the prior week. Yet nearly two-thirds of respondents with fecal incontinence said they never used any form of barrier protection like pads or diapers.4Gastroenterology. Prevalence of and Factors Associated With Fecal Incontinence: Results From a Population-Based Survey That gap between experiencing leakage and actually using a product hints at how much stigma and avoidance shape the real numbers.
Among those who do use absorbent products for fecal incontinence specifically, women and older adults are overrepresented. One study found that 45% of community-living adults with fecal incontinence used an absorbent product, and 88% of those users were women.5PubMed Central. Use and Evaluation of Disposable Absorbent Products for Managing Fecal Incontinence by Community-Living People The people who resort to diapers or pads tend to have more severe symptoms, which makes intuitive sense but also means the mildest cases are chronically underrepresented in product-use statistics.
Why Women Use Incontinence Products at Much Higher Rates
The gender gap in diaper use is stark. Where about 6% of men in one nationwide survey used incontinence products, the figure for women was closer to 16%.1PubMed. Association between incontinence product use and quality of life in adult men: results from a nationwide survey The anatomy of the female pelvic floor, combined with the physical demands of pregnancy and vaginal delivery, accounts for much of this difference.
Postpartum incontinence is surprisingly common. Two separate studies found that roughly 34% to 36% of women report some degree of urinary leakage within three months of giving birth.6PubMed. Obstetric practice and the prevalence of urinary incontinence three months after delivery7International Journal of Urological Nursing. Examining prevalence of urinary incontinence and risk factors in women in third postpartum month For most, the leakage is mild and improves over time. For a smaller subset, though, it persists and worsens with subsequent pregnancies, eventually requiring daily pad or diaper use years later.
Menopause compounds things further. Declining estrogen thins the urethral lining and weakens pelvic-floor muscles, pushing prevalence upward through the fifth and sixth decades of life. A population-based study in women found that the age-specific rate of fecal incontinence climbed steadily with age through the sixties.8Gastroenterology. Prevalence and Burden of Fecal Incontinence: A Population-Based Study in Women When you add urinary and fecal incontinence together, it becomes easier to understand why incontinence products aimed at women outsell those for men by a wide margin.
Post-Prostate Surgery and Male Incontinence
For men, the single biggest driver of diaper use is surgery for prostate cancer. The prostate sits right next to the urinary sphincter, and removing it can damage the muscle responsible for keeping urine in. One study tracking men after prostatectomy found that about 59% were using pads six weeks after surgery; by a year out, that number had dropped to roughly 22%.9PubMed Central. Risk of Urinary Incontinence Following Prostatectomy: The Role of Physical Activity and Obesity Those are strikingly high numbers considering that prostate cancer is one of the most commonly diagnosed cancers in men.
Even newer surgical techniques have not eliminated the problem. Robot-assisted radical prostatectomy, now the dominant approach in many countries, still carries a meaningful risk of postoperative incontinence that may require ongoing pad use and can significantly affect quality of life.10International Journal of Urological Nursing. Urinary Incontinence, Pads and Health‐Related Quality of Life After Robot‐Assisted Radical Prostatectomy The majority of male incontinence seen clinically traces back to sphincter weakness following some form of prostate surgery, and as both the elderly population and the number of prostate-cancer interventions grow, male incontinence rates are increasing.11PubMed Central. Management of male urinary incontinence
Neurological Conditions and Cognitive Decline
Incontinence is not always a plumbing problem. The brain and spinal cord coordinate bladder and bowel function through a complex signaling chain, and when that chain gets disrupted, the result is often involuntary leakage. Stroke and spinal cord injury are two of the most common culprits, producing what clinicians call neurogenic voiding dysfunction.12PubMed Central. Neurogenic Voiding Dysfunction in Spinal Cord Injury and Stroke: Urodynamic Evaluation, Functional Classification, and Therapeutic Strategies Multiple sclerosis, Parkinson’s disease, and spina bifida also commonly produce incontinence that erodes quality of life and often leads to long-term diaper use.13PubMed Central. Health-related quality of life and economic impact of urinary incontinence due to detrusor overactivity associated with a neurologic condition: a systematic review
Dementia adds a distinct wrinkle. Many people with dementia retain physical continence for years, but cognitive decline can erode the awareness of when to go, the ability to find a bathroom, or the coordination needed to manage clothing in time. An ethnographic study in hospital wards found deeply embedded “pad cultures” in which continence pads were routinely placed on dementia patients regardless of whether they were actually incontinent. Staff viewed pads as a precautionary strategy to prevent accidents, and there was a blanket expectation that people living with dementia would both wear and use them.14Health and Social Care Delivery Research. Understanding approaches to continence care for people living with dementia in acute hospital settings: an ethnographic study This is a troubling finding because unnecessary pad use can accelerate loss of independence and worsen skin problems, creating a self-fulfilling cycle.
The Financial Burden
Diapers and pads are a recurring expense with no natural endpoint. Women who used incontinence products weekly reported spending a median of about $3 per week, though the average was pulled higher by heavy users, reaching a mean of roughly $5.40 a week with some individuals spending up to $100.15PubMed Central. The burdens of incontinence: Quantifying incontinence product usage and costs in women That might sound manageable until you realize it compounds over years and often coincides with other rising healthcare costs.
For men with prostate cancer, the economic hit extends well beyond the products themselves. A study analyzing U.S. Medical Expenditure Panel Survey data from 2016 to 2021 found that urinary incontinence imposes a significant economic burden on prostate-cancer survivors, driven by increased outpatient visits and non-clinical expenditures like medical supplies. Disparities in insurance coverage and socioeconomic status made this burden worse for those with fewer resources.16Urology. Economic Burden of Urinary Incontinence in Men With Prostate Cancer: Results From the Medical Expenditure Panel Survey (2016-2021) In the United States, Medicare covers some incontinence supplies for homebound beneficiaries, but many private insurance plans do not cover disposable products at all, leaving the cost entirely to the individual.
Skin Health Risks From Prolonged Use
Wearing a diaper for hours at a time is not without physical consequences. Prolonged or repeated contact between skin and urine or feces can cause incontinence-associated dermatitis, a type of irritant skin reaction marked by redness, pain, softening of the skin, erosion, and scaling. Secondary infection is common once the skin barrier breaks down.17PubMed Central. Incontinence-Associated Dermatitis in Older Adults: A Critical Review of Risk Factors, Prevention and Management Friction from the product itself can aggravate the damage, and older adults are especially vulnerable because aging skin is thinner and more fragile.18PubMed. Incontinence-Associated Dermatitis: Pathogenesis, Contributing Factors, Prevention and Management Options
Prevention centers on frequent changes, barrier creams, and proper sizing. Products with superabsorbent polymer particles can wick moisture away from the skin more effectively than older fluff-pulp designs, and they help control pH, which matters because alkaline urine is especially irritating.19International Nonwovens Journal. Nonwovens Containing Immobilized Superabsorbent Polymer Particles Even with good product technology, though, nothing replaces regular skin checks and timely product changes, particularly for people who cannot change themselves.
Why Most People Never Bring It Up With a Doctor
Given how treatable many forms of incontinence are, it’s remarkable how few people ever discuss it with a healthcare provider. A nationwide study in Saudi Arabia examined the barriers and found that embarrassment consistently topped the list, followed by a preference for a same-sex physician and simple lack of knowledge that treatment options exist. Among adults over 45, nearly 40% rated the same-sex physician preference as a major barrier.20PubMed Central. Barriers to Seeking Medical Consultation for Urinary Incontinence: A Nationwide Population‐Based Study in Saudi Arabia While those specific percentages come from a Saudi population, the themes are echoed in studies worldwide: shame, normalization of leakage as “just part of aging,” and unawareness that pelvic-floor therapy, medications, or surgery could help.
The emotional weight compounds quietly. Living with incontinence affects social outings, intimate relationships, and self-image. One personal account published in a nursing journal described double incontinence as a condition that reshapes daily life not just for the person affected but for their caregivers as well. The large Chinese study mentioned earlier found an interesting silver lining: among incontinent elderly people who used diapers, the odds of going out at least once a month were actually better than for those who did not use them, suggesting that having a reliable containment strategy can partially restore the willingness to leave the house.3PubMed Central.

Adult Baby and Diaper Lover Communities
Not all adult diaper use is medical. A subset of adults wear diapers as part of a sexual or comfort-related behavior known as ABDL (Adult Baby/Diaper Lover). The largest survey of this community included nearly 2,000 members and found that most participants were male, most identified their ABDL interests as having started in childhood, and both men and women described a component of wanting to feel dominated or nurtured. The study noted that most participants were comfortable with their behavior and reported few related problems.21PubMed. Adult baby/diaper lovers: an exploratory study of an online community sample
A smaller Italian study explored psychological characteristics in more depth, finding that ABDL adults scored higher than population norms on measures of anxiety, depression, and perceived parental rejection.22PubMed Central. An Exploratory Study of Adult Baby-Diaper Lovers’ Characteristics in an Italian Online Sample Whether those elevated scores are a cause or a consequence of the behavior, or simply a reflection of belonging to a heavily stigmatized subculture, is an open question. The research in this area is still sparse, and sample sizes are small enough that broad conclusions would be premature. What is clear is that this population exists, is larger than most people assume, and is distinct from the medical-incontinence population in both motivation and experience.
The Growing Environmental Problem
Used adult diapers are one of the fastest-growing segments of municipal waste in aging societies, and the numbers are startling. Modeling for Australia projected that by 2030, absorbent hygiene product waste from adults will be four to ten times larger than that from infants, driven by demographic aging.23Waste Management. Adult incontinence products are a larger and faster growing waste issue than disposable infant nappies (diapers) in Australia Across OECD countries, adult diapers already account for an average of about 4.8% of municipal waste by weight, outpacing baby diapers at 2.7%.24PubMed. Waste management and environmental impact of absorbent hygiene products: A review
The products themselves are a recycler’s nightmare. A used adult diaper is roughly 60% urine and feces by mass, with the remaining solid material containing about 20% non-biodegradable synthetic components like superabsorbent polymers and plastic backsheets. In Australia, about half of these products end up in landfills equipped with both leachate and biogas collection, but the other half goes to facilities without those safeguards.23Waste Management. Adult incontinence products are a larger and faster growing waste issue than disposable infant nappies (diapers) in Australia Industrial composting or recycling of used diapers exists in pilot form in a few countries but remains far from mainstream. The persistent synthetic composition of adult diapers, combined with regulatory and infrastructure gaps, means that landfill disposal is the norm almost everywhere.25Journal of Circular Economy. Adult Diaper Waste in Landfills: A Critical Review of Systemic Failure and Pragmatic Pathways
Access Gaps in Lower-Income Countries
The picture changes dramatically outside wealthy nations. In Pakistan, a qualitative study found that adult diapers were largely unavailable, prohibitively expensive, and not considered suitable for regular use by the people who needed them.26PLOS ONE. Managing incontinence in low-and middle income-countries: A qualitative case study from Pakistan People improvised with cloth, towels, or simply stayed home. In sub-Saharan Africa, a similar pattern emerges: diapers can be bought without a prescription and are sometimes the only management option available because surgical and therapeutic services for incontinence are scarce, yet the cost adds a financial burden on top of the condition itself.27Frontiers in Urology. Urinary incontinence among women in sub-Saharan Africa – an overview
In these settings, government health systems tend to rank incontinence treatment as a low priority compared with infectious disease, maternal mortality, and other acute needs. The result is a population of people, disproportionately older women, whose incontinence goes unmanaged or poorly managed, often leading to social isolation, skin breakdown, and preventable infections. The contrast with wealthier countries, where the concern has shifted from product availability to environmental impact of product disposal, underscores how much context matters when talking about who wears diapers and why. Incontinence itself is a near-universal human vulnerability, but the experience of managing it depends enormously on where you happen to live.
