Many diseases.Young people become obese or overweight because they

Many studies have been done to examine the connection and the relationship between depression and obesity. High body mass index (BMI) has been associated with depression but the association is uncertain. Some studies have also suggested that an adolescent obesity is a strong predictor of adulthood obesity and it is associated with depression, especially in women and young girls.Obesity is defined as an excessive fat accumulation. The body mass index (BMI) is a number using as an indicator of underweight, overweight and obesity. The BMI is equal to the body weight divided by the height squared. In adults, if BMI is from twenty-five to thirty is regarded as an overweight, if BMI is greater than thirty or equal thirty, it means that the person is obese. BMI varies with age and gender.Obesity makes people more likely to have conditions including heart disease and stroke, high blood pressure, diabetes, osteoarthritis, etc. But not everyone who is obese has these problem, some of this problem can be hereditary.Overweight and obesity in childhood have important impact on physical and physiological health. Obese children are likely to stay obese and overweight in adulthood and are more likely to develop diseases such as diabetes and cardiovascular diseases.Young people become obese or overweight because they do not have enough physical activity or if they have bad eating habits. Genetics also participate to a child´s weight status. If you want to prevent obesity change eating habits, have more physical activity and better lifestyle – avoid to alcohol and smoking.Depression is a serious condition that affects your physical and especially mental health. Depression can affect thoughts, behaviour and feelings of person. Many physical problems are connected to depression for example problems with sleeping (insomnia or hypersomnia) and problems with appetite.Gender, age, ethnicity and socioeconomic status, in other words mediators, affect the relationship between obesity and depression. For example, an association can exist in black youth, but not in white youth. Some studies also showed differences in sex – obese girls more inclinable to depression than obese boys. Also, there is a difference between black and white female adolescents. White females tend to see themselves as obese or overweight when clinically they are not, this leads to low self-esteem and bad weight management.Generally, it is important to recognize moderators such as gender or age to recognize those obese adolescents which might have tendencies to be depressed.Mediators determine how and why moderators such as age, gender, ethnicity, etc. influence causal effect of obesity onto depression. Body dissatisfaction is mediator for the obesity and bullying relationship. Studies found that obese adolescents are at an increased risk for depression because of peer victimization. Peer victimization is enmity toward children by other children in none family relationship. Thus, obesity may lead to peer victimization and this may lead to depression among children and youth. Therefore, obese children are inclinable to become depressed because of bullying by their peers.For long time it has been assumed that any connection between depression and obesity in the general population is largely adventitious, but some recent subanalysis and studies (Luppino and colleagues) found that the effect of obesity on development of depression was stronger in American studies. Luppino and his colleagues highlighted biological ling between overweight, obesity and depression. By Luppino and his colleagues is obesity seen as an inflammatory. Inflammation is also connected with depression, in this
