Rawal Prevention of Excessive Weight Gain in Adults Age 20 Years and OlderOverview of Weight GainObesity has taken its toll to a great extent in rural America, affecting people of all demographics and of all ages. Obesity is not a problem of poor and middle-class people in third world countries anymore. It is prevalent among affluent communities throughout the world. It has truly become a worldwide problem, affecting rich and poor across the globe. According to an article published by Harvard School of Public health, it is estimated that roughly 500 million adults are obese throughout the world. This increase includes almost ten percent of men and 14 percent of women, which has nearly doubled the rate of obesity since 1980. It greatly affects many demographics such as Caucasians, African Americans, Hispanics, Native Americans, Asians and Pacific Islanders. In North America, obesity rates are higher in non-Hispanic blacks, Hispanics and Mexican American adults than in non-Hispanic white adults.1 According to one study, it is estimated that Non-Hispanic Black women have the highest rates of obesity in the US, which is close to 59 percent, compared to other ethnicities.2It is predicted that if this trend continues in the United States, roughly half of all men and women will be obese by 2030.2According to the Center for Disease Control and Prevention (CDC), high rates of morbidity and mortality are seen among these populations. An estimated of 300,000 US adults die each year due to obesity and other obesity related non-communicable diseases such as type 2 diabetes and cardiovascular diseases.1CausesObesity is an accumulation of excess fat in the human body, when more calories are consumed than the body burns and the excess calories are stored as fat. It is also defined as an
Rawal individual with a body mass index (BMI) of 30 or higher.3It is important to know the causes of obesity because it is a serious public health problem, which is associated with some of the leading causes of death in the U.S and worldwide. The cause of obesity is well recognized to be multi-factorial, and it includes genetic, nutrition and physical activity. Genetics plays an import role in causing obesity. Human body is instructed by pool of genes for responding to the changes in it environment.4There are some studies which have demonstrated a close link between obesity and genetics. One study published by CDC identified modification in several genes that could be responsible for obesity by increasing hunger and food intake. The same study also proposed an indirect scientific evidence that sizable portion of the variation in weight among adult is due to genetic factors. “Most obesity, however, probably results from complex interactions among multiple genes and environmental factors that remain poorly understood.”4 Lifestyle BehaviorsIndividual lifestyle behaviors such as smoking, poor diet, physical inactivity and alcohol consumption are some of the major contributors of obesity and other obesity related diseases.
