Summary
Urinary incontinence (UI) in older women is linked to central obesity, including higher visceral fat and waist circumference. Maintaining a normal BMI offers protection, suggesting interventions targeting fat reduction and chronic disease management may improve urinary health.
Area of Science:
- Gerontology
- Urology
- Public Health
Background:
- Urinary incontinence (UI) significantly impacts older women's quality of life and healthcare costs.
- Understanding the relationship between body composition and UI is crucial for targeted interventions.
Purpose of the Study:
- To investigate the association between UI and body composition (visceral fat, waist circumference, muscle mass) in older Iranian women.
Main Methods:
- A case-control study involving 845 women aged ≥60 years.
- Body composition analyzed using dual-energy X-ray absorptiometry (DXA).
- Multivariate logistic regression identified predictors of UI.
Main Results:
- UI prevalence was 52.5%; UI cases had higher obesity rates, larger waist circumference, and increased visceral fat.
- Normal BMI (<25) was associated with 48% lower odds of UI compared to obesity.
- Each additional chronic disease increased UI risk by 40%.
Conclusions:
- Central obesity and chronic diseases are strong predictors of UI in older women.
- Normal BMI demonstrates a protective effect against UI.
- Interventions focused on reducing visceral fat and managing comorbidities may enhance urinary health.

The nursing assessment of the genitourinary (GU) system involves a systematic inspection and palpation to identify abnormalities in the kidneys, bladder, and surrounding structures.InspectionMouth: Inspect for signs of kidney dysfunction, such as stomatitis (inflammation of the mouth) and ammonia breath, which may occur in advanced kidney disease due to the buildup of urea, breaking down into ammonia.Skin: Check for pallor, which could indicate anemia caused by kidney disease.

Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

The genitourinary system is critical to maintaining fluid balance, waste elimination, and reproductive function. Nurses play a vital role in assessing this system, beginning with a thorough health history. This process involves gathering patient information, identifying risk factors, and recognizing symptoms of genitourinary disorders. Early detection is vital for timely interventions and management.1.

01:23Urinary Bladder
4.6K
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

2.1K
Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...

The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
