Is obesity an epidemiological concern?

Literature supporting increased morbidity in obese individuals is quite overwhelming. Epidemiological studies have shown the links between obesity and adverse health outcomes, and physiological mechanisms are provided to support these relationships.

How does obesity relate to epidemiology?

Obesity greatly increases risk of chronic disease morbidity—namely disability, depression, type 2 diabetes, cardiovascular disease, certain cancers—and mortality. Childhood obesity results in the same conditions, with premature onset, or with greater likelihood in adulthood (6).

What is epidemiological triangle?

A number of models of disease causation have been proposed. Among the simplest of these is the epidemiologic triad or triangle, the traditional model for infectious disease. The triad consists of an external agent, a susceptible host, and an environment that brings the host and agent together.

What is the agent in obesity?

In the case of obesity, the World Obesity Federation argues, foods with high energy density are the primary agent, alongside other environmental factors such as low physical activity.

When did obesity become a problem?

According to the findings, the obesity epidemic spread rapidly during the 1990s across all states, regions, and demographic groups in the United States. Obesity (defined as being over 30 percent above ideal body weight) in the population increased from 12 percent in 1991 to 17.9 percent in 1998.

What are the 3 major types of epidemiological studies?

Three major types of epidemiologic studies are cohort, case-control, and cross-sectional studies (study designs are discussed in more detail in IOM, 2000). A cohort, or longitudinal, study follows a defined group over time.

What environmental factors affect obesity?

Environmental factors like high fat foods, super-sized portions, fast food consumption play a major role in occurrence of obesity. Individuals are addicted to high fat and calorie, highly palatable and inexpensive foods. Behaviour is one of the factors influencing weight gain.

Who obesity epidemiology?

Of these over 650 million adults were obese. In 2016, 39% of adults aged 18 years and over (39% of men and 40% of women) were overweight. Overall, about 13% of the world’s adult population (11% of men and 15% of women) were obese in 2016. The worldwide prevalence of obesity nearly tripled between 1975 and 2016.

What is the epidemiology of obesity in the world?

The epidemiology of obesity Obesity is a complex multifactorial disease. The worldwide prevalence of overweight and obesity has doubled since 1980 to an extent that nearly a third of the world’s population is now classified as overweight or obese. Obesity rates have increased in all ages and both sexes irrespective of geograph …

How does the epidemiologic triangle help your students?

The Epidemiologic Triangle is a model that scientists have developed for studying health problems. It can help your students understand infectious diseases and how they spread. and facts.

How many people in the world are obese?

Obesity is a complex multifactorial disease. The worldwide prevalence of overweight and obesity has doubled since 1980 to an extent that nearly a third of the world’s population is now classified as overweight or obese.

Which is the vertex of the epidemiologic triangle?

Here are more details on the parts of the Epidemiologic Triangle: Vertex 1. The Agent—“What” The agent is the cause of the disease. When studying the epidemiology of most infectious diseases, the agent is a microbe—an organism too small to be seen with the naked eye. Disease-causing microbes are bacteria, virus, fungi, and protozoa
