Experimental: Eating and physical activity counseling Behavioral: Eating and physical activity counseling

The parents of overweight children will be invited to attend a total of 6 group sessions (the group will be comprised of 6 children with their parents) on a weekly basis, in which 5 aspects will be dealt with 1) Dietary culture, risk-benefit practices, 2) The process of feeding (acquisition/preparation/service Eating behaviors), 3) Physical activity habits, 4) Importance of weighing/measuring oneself and its meaning, 5) feedback and evaluations.

Detailed Description:

Obesity has a multi-causal origin in which participate, in a similar way, the individual behavior and family and community contexts and the social environment.

Participation of primary care services is key to solve the problem. These services have the possibility to detect timely children with high body mass index, and to promote behavior to improve feeding practices and physical activity in both, the child and his family.

The study is divided in two stages:

  1. Design of the intervention. The researchers will use qualitative methods to evaluate feeding practices, physical activity and the environment in which such behaviors are generated. In a similar way the care provided by health professionals to overweight and obese children it will be evaluated; this includes the perception that health providers have about this problem. The information will allow identifying risk behavior and healthy behavior, facilitators and obstacles to receive care. The results will serve to define the contents of the intervention.
  2. Intervention: The study will take place in four family medicine clinics belonging to the Mexican Institute of Social Security. Two clinics will receive the intervention and two will serve as control. In each clinic, fifty children and their mothers will be recruited. At the intervention clinics, the group of mothers will participate in seven weekly sessions and in two individual sessions at 3 and 6 months after the group sessions finish. During the sessions, the researchers will motivate the mothers to change feeding practices and encourage physical exercise of the children and family, this will improve the chance for their children for healthy growing. The control group will receive the usual care that consists only in the recommendations that the family doctor provides.

The evaluation of the study comprise feasibility and acceptability of the intervention and its effect in the behavior of the mothers in terms of changing feeding practices and practicing physical exercise.
