Obesity

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Binge Eating Disorders

Binge Eating Disorders

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Bulimia Nervosa

Bulimia Nervosa

Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Stress Prevention and Stress Management Techniques IV

Stress Prevention and Stress Management Techniques IV

Stress often leads to unhealthy habits like smoking, excessive drinking, and overeating, which offer short-term relief but ultimately increase long-term health risks. These behaviors create a cycle that temporarily lowers stress levels but can result in severe long-term health consequences. Breaking these habits is essential to reduce the risk of chronic diseases and improve overall well-being. Three primary changes that support better health include quitting smoking, reducing alcohol intake,...

Anorexia Nervosa

Anorexia Nervosa

Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.
Symptoms and Physical Effects
Individuals with anorexia nervosa commonly exhibit extreme...

Applications of GIS: Disaster Management and Emergency Response

Applications of GIS: Disaster Management and Emergency Response

Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

Area of Science:

Public Health
Environmental Health
Epidemiology

Background:

Natural disasters trigger long-term health issues, notably obesity, a precursor to noncommunicable diseases like cardiovascular disease, diabetes, and cancer.
This systematic review investigates the association between natural disasters and obesity, alongside contributing risk factors.

Approach:

A comprehensive literature search was performed across major scientific databases (PubMed, Scopus, Web of Science, HINARI, Google Scholar) supplemented by manual searches.
Studies reporting weight gain and associated risk factors following natural disasters were included. Study quality was assessed using Joanna Briggs Institute (JBI) tools, and data were synthesized.

Key Points:

The review analyzed 17 cohort studies with participants aged 3 months to 67 years, focusing on children, adults, and adolescents.
Post-disaster weight gain was observed, with identified risk factors including sedentary lifestyles, poor nutrition, maternal high Body Mass Index (BMI), stress, and environmental factors like temporary housing.

Conclusions:

Addressing post-disaster obesity is crucial for public health, requiring integration with immediate disaster response priorities like trauma care.
Effective strategies are needed to mitigate the intergenerational impact of obesity following natural disasters, informing policy development.
