Physical Activity  epidemiology  is a foundational domain within population health science that examines the distribution, determinants, patterns, and health consequences of physical activity across diverse populations and life stages, integrating behavioral science, biostatistics, environmental health, and chronic disease  epidemiology  to understand how movement influences morbidity, mortality, and health equity at a population level; it investigates how age, sex, socioeconomic status, culture, urbanization, technology use, occupational demands, and built environments shape physical activity behaviors, and how these behaviors in turn modify risks for non-communicable diseases such as cardiovascular disease, type 2 diabetes, obesity, hypertension, osteoporosis, selected cancers, depression, and cognitive decline, while also contributing to musculoskeletal health, immune resilience, metabolic regulation, and overall longevity; guided by global frameworks advanced by ...

Nutrition transition and lifestyle diseases represent one of the most profound public health challenges of the 21st century, reflecting the rapid and complex shifts in dietary patterns, physical activity, and overall living conditions that accompany economic development, urbanization, globalization, and technological advancement across the world, particularly in low- and middle-income countries such as India. Traditionally, human diets were largely based on whole grains, legumes, fruits, vegetables, and minimally processed foods, accompanied by high levels of physical activity due to agrarian occupations and manual labor, but over the past few decades, these patterns have shifted dramatically toward diets rich in refined carbohydrates, saturated and trans fats, added sugars, salt, animal-source foods, and ultra-processed products, while daily energy expenditure has declined sharply due to sedentary work, motorized transport, screen-based entertainment, and reduced occupational physical...

  Climate-induced vector-borne diseases represent one of the most critical and rapidly evolving public health challenges of the 21st century, emerging from the complex and accelerating interactions between global climate change, ecological transformation, socioeconomic vulnerability, and human mobility, as documented extensively by World Health Organization and assessed through climate risk frameworks developed by the Intergovernmental Panel on Climate Change , wherein rising global temperatures, altered precipitation patterns, intensified heatwaves, sea-level rise, deforestation, and extreme weather events such as floods, droughts, and cyclones are reshaping the geographical distribution, seasonality, and transmission dynamics of vectors including mosquitoes, ticks, sandflies, and triatomine bugs, thereby expanding the global footprint of infectious  diseases  such as Malaria , Dengue , Zika , Chikungunya , Yellow fever , Japanese encephalitis , West Nile fever , Lyme d...

Occupational exposure to chemicals represents one of the most pervasive and complex hazards in modern workplaces, encompassing a vast spectrum of substances including industrial solvents, heavy metals, pesticides, acids, alkalis, gases, fumes, dusts, fibers, and emerging synthetic compounds that workers may encounter across manufacturing, agriculture, mining, healthcare, construction, laboratories, waste management, and service industries, with exposure occurring through inhalation, dermal absorption, ingestion, or accidental injection, often in combinations that complicate toxicological prediction and risk assessment; the health consequences of such exposures are multifactorial, ranging from acute effects such as  chemicals  burns, irritation of the skin and mucous membranes, respiratory distress, dizziness, nausea, and chemical pneumonitis to chronic outcomes including occupational asthma, chronic obstructive pulmonary disease, liver and kidney dysfunction, neurotoxicity, re...

  Noise pollution is one of the most pervasive yet underestimated environmental health hazards in modern society, emerging as a direct consequence of rapid urbanization, industrial growth, transportation expansion, and unregulated technological development, and it is now formally recognized by World Health Organization as a major environmental determinant of health alongside air and water pollution, with sound levels above recommended limits affecting billions of people daily in cities such as Delhi , Mumbai , New York City , Tokyo , and London , where traffic congestion, aviation activity, construction operations, industrial machinery, amplified social events, and densely packed residential settings generate continuous sound exposure that frequently exceeds safe thresholds of 55 dB during the day and 40 dB at night, transforming  Noise  from a mere nuisance into a chronic environmental stressor that disrupts physiological homeostasis and psychological well-being, with ...
