Special Issue Information

Dear Colleagues,

Obesity is one of the most pressing global public health challenges of the 21st century. Its rapid rise across both high- and low-income countries is driven by complex, interrelated factors including urbanization, sedentary lifestyles, dietary transitions, socioeconomic disparities, and environmental influences. As obesity continues to fuel a cascade of chronic diseases such as type 2 diabetes, cardiovascular diseases, certain cancers, and musculoskeletal disorders, there is an urgent need for population-level, systems-oriented solutions. 

This Special Issue seeks to provide a platform for original research and review articles that examine the population health implications of obesity and propose multilevel strategies for prevention, management, and policy response. 

We welcome submissions from a broad range of public health perspectives, including but not limited to 

  • Social and structural determinants of obesity; 
  • Health systems and policy responses; 
  • Community and environmental interventions; 
  • Life-course approaches to obesity prevention; 
  • Health promotion and education; 
  • Urban planning, food systems, and built environment;
  • Economic evaluations of obesity-related interventions; 
  • Cultural and indigenous perspectives; 
  • Technological and digital health approaches; 
  • Multidisciplinary, intersectoral, and equity-focused work is particularly encouraged. 

We invite researchers, practitioners, and policymakers to contribute evidence that informs action and translates knowledge into meaningful population health outcomes. We welcome high-quality original research, systematic reviews, meta-analyses, commentaries, and perspectives that contribute to a deeper understanding of obesity burden and offer practical or policy-oriented solutions.

Background: Excess body weight is a major global health problem and an established independent risk factor for chronic kidney disease (CKD). This study aimed to determine the prevalence of overweight and obesity and to evaluate sex-, age-, and time-related trends—including the COVID-19 period—among patients treated at the Outpatient Clinic of the Division of Nephrology, Dialysis and Arterial Hypertension, University Hospital of Split, from 2016 to 2024. Methods: This study included 3033 subjects over 18 years of age, 44.8% men and 55.2% women with a mean age of 60 years. Body composition was assessed using the Tanita MC-780 bioelectrical impedance analyzer and body mass index (BMI, kg/m2) was measured. Results: The study population had median BMI of 28.0 kg/m2, with 33.1% overweight and 37% obese participants, including 6.6% with class III obesity. Men showed greater muscle and bone mass (p < 0.001), whereas women had higher fat mass and obesity prevalence (38.2% vs. 35.6%, p < 0.001). Participants under 65 years had higher absolute fat and muscle mass but similar fat percentage compared to older adults. Overweight and obesity prevalence increased with age, peaking at 75–78% in the 55–74-year group. BMI and fat mass rise significantly during and after the COVID-19 period, while phase angle values declined. Conclusions: Excess body weight is highly prevalent in nephrology patients, particularly in middle-aged adults. The COVID-19 pandemic further worsened body composition indicators, reinforcing the need for preventive strategies. Full article

Violence is an emerging social determinant of health in Latin America; however, empirical evidence from Peru remains limited. This study examined the association between crime rates and the prevalence of obesity and high blood pressure in Peru from 2019 to 2023. Using a repeated cross-sectional design with department–year aggregates, we analyzed nationally representative data from the Demographic and Family Health Survey, adjusting for sociodemographic, mental health, and geographic factors. Regional statistics on crime were incorporated into the analysis. The findings revealed a significant association between higher levels of crime and increased prevalence of self-reported high blood pressure and obesity. The association with obesity was particularly pronounced in border regions such as Tumbes, Madre de Dios, and Callao, where criminal activity is more prevalent. The findings indicate that prolonged exposure to violence may negatively impact biological stress responses, limit physical activity, and encourage the emergence of detrimental behaviors, consequently increasing the cardiometabolic risk burden in affected populations.
