The aim of this study was to examine the effects of the Family-Based Health Behavior Development Program (FHEBIP) on obesity risk factors and body mass index (BMI) to prevent the increasing prevalence of overweight and obesity in children. The randomized controlled trial sample consisted of 96 fourth-grade primary school students and their mothers in Aksaray province. Data were collected using questionnaires and the Family Nutrition and Physical Activity Scale, and height and weight measurements were taken. Ethics committee and institutional approvals were obtained.

Obesity is an important public health problem due to the many chronic and non-chronic diseases it causes. It is not only seen in adults, but its prevalence is increasing in children. According to WHO 2018 statistical reports; While the prevalence of overweight (obesity) in children aged 5-19 was 4% in 1975, it increased to 18% in 2016. While 43 million children were obese in 2010, according to 2016 statistics, 340 million children and adolescents were overweight or obese in the world. One in every four children in European countries and one in every three children in the United States of America (USA) are obese.

In the studies conducted by the Ministry of Health, we see that the prevalence of obesity in children increases as the age groups change and the years increase. In order to prevent the increase in the prevalence of obesity, states globally offer various research and development (R&D) studies, incentives and support this with laws and regulations. Turkey, as one of these countries, closely follows the activities and takes part in the projects as a collaborator Although the causes of CBO are not fully known, it is known that many factors play a role in the development of CBO. Although the general mechanism is accepted as the energy intake being higher than the energy expenditure, there are factors that cause or support the development of obesity. Genetic factors, metabolism, hormones, psychological factors, sleep, screen time, socioeconomic level differences, unhealthy eating habits and physical inactivity, perinatal characteristics such as delivery method, birth weight and some environmental factors have been proven by studies to cause obesity. The vast majority of the causes of CBO are external factors (environmental factors) and excess energy intake, while a small portion is made up of biochemical factors such as genetic and endocrine causes. Studies on childhood overweight and obesity indicate four main environmental factors. These factors are nutrition, physical activity, screen time and sleep.

In addition to the many factors that cause obesity, there are also various health problems that obesity brings with it. Children with CSA, in particular, have a higher risk of early onset of chronic diseases such as cardiovascular diseases, diabetes and hypertension, and psychological distress such as anxiety, depression, social stigma and bullying. The variety of factors that cause CSA, the difference in obesity management according to developmental stages in children, basic differences in family factors, the high probability of those who are obese in childhood to become obese in adulthood, chronic diseases caused by CSA and the scarcity of randomized controlled trials (RCTs) in this area indicate that more research with high level of evidence is needed.
