Public health concepts and applications

Public Health: Overweight/Obesity

Struggling with weight is one of the most serious health problems faced by the American Public. According to the Guide to Community Preventive Services (2003), more than half of the adult American population is overweight or obese. Indeed, studies have shown that weight problems begin with habits formed during childhood and youth. These habits are cultivated both in the home, in the workplace and in the school community. Education is therefore of primary importance.

For this reason, several preventive measures have been implemented and studied for their effectiveness. In schools, several programs have for example been implemented to cultivate healthier eating and fitness habits in young children. The programs are managed by specially trained personnel, who promote healthy habits by means of "fun" activities both in the home and school.

In the workplace, programs have been incorporated in a multi-functional paradigm: combination of education, increased physical activity, and healthier nutritional habits has resulted in promising short-term results. The problem is however that results appear less promising in the long-term. The most effective period for weight loss occurs during the first six months, whereas weight gain once again appears after this time.
