Sanitation, Obesity, and Low Body Mass Index as Risk Factors for Bacterial Skin Infections

Area of Science:

• Global health
• Epidemiology
• Infectious diseases

Background:

• Bacterial skin infections pose significant global health risks, leading to disability and mortality.
• Inadequate treatment exacerbates the severity and outcomes of these infections.

Purpose of the Study:

• To investigate the statistical significance of sanitation and body mass index (BMI) as risk factors for bacterial skin infection incidence and prognosis.
• To analyze the relationship between sanitation, obesity, and underweight on the global burden of bacterial skin infections.

Main Methods:

• Utilized country-level data on bacterial skin infection incidence, prevalence, and years lived with disability (YLD) from the Global Burden of Disease study.
• Incorporated World Health Organization data on age-standardized prevalence of obesity (BMI ≥30) and low BMI (BMI <18.5).
• Employed regression models to assess the impact of sanitation, obesity, and low BMI on bacterial skin infection burden.

Main Results:

• Higher rates of basic sanitation access correlated positively with increased incidence, prevalence, and YLD of bacterial skin infections.
• In regions with over 50% basic sanitation coverage, obesity was linked to a greater burden of bacterial skin infections.
• Conversely, in areas with 50% or less basic sanitation coverage, low BMI was associated with a higher burden of bacterial skin infections.

Conclusions:

• Enhancing global access to sanitation is crucial for reducing bacterial skin infection burden.
• Targeted interventions are needed: reducing obesity in well-sanitated regions and addressing malnutrition in areas with poor sanitation.
