Recommendations

PRIMARY PREVENTION OF CHILDHOOD OBESITY
SUGGESTIONS TO INCREASE PHYSICAL ACTIVITY
1. Limit television, computer time and video games to approximately 2 hours per day.
2. Plan family activities for the weekend. These activities can include bike riding, hiking, trips to the zoo, museum or library, and house or yard projects.
3. Walk the dog. 4. Take family walks. Walk with friends instead of talking with
them on the telephone. 5. Play outdoors every day. If it is raining or snowing, dress
appropriately and still go outside to play in the snow or puddles. 6. Define indoor areas for physical play such as ‘Nerf’ balls, bouncy
balls or scooter toys.

PRIMARY PREVENTION OF CHILDHOOD OBESITY
TIPS TO MODIFY EATING BEHAVIOR
1. Families should eat together at the dinner table. The family table encourages discussion, problem solving and interaction which diverts attention from eating thereby slowing the process and allowing for satiety to develop more naturally.
2. Establish routine daily family meal and snack times. 3. Television should be turned off during meals. Television tends to
stimulate children to eat more. 4. Slow down eating. Meals should last at least 20 to 30 minutes to
allow enough time for the normal sensations of fullness and satiety to be felt.
5. Prepare plates in the kitchen rather than allow self serve. 6. Eat regularly, 3 meals a day with 1 snack a day for children. This
prevents excessive hunger and overeating.

Dear Parent, Your child has been identified as being overweight or obese. As you know, childhood obesity rates have reached epidemic proportions. A recent study showed that 37% of Houston area school children are overweight or obese. We are concerned because the health consequences of being overweight are very serious and can cause many associated diseases. The most severe and life threatening obesity related diseases seen in children include sleep apnea (sudden cessation of breathing while asleep), diabetes and liver disease caused by fat accumulation in the liver. These diseases were very rare in children until recently but now because of the obesity epidemic doctors are diagnosing them routinely in overweight children. Children can also develop problems with both the hip and knee joints that can lead to permanent disability when obesity puts increased weight on their legs. Other chronic diseases associated with obesity in children include high blood pressure, gall bladder disease, high blood cholesterol, and polycystic ovary disease in girls. Many children who are overweight develop poor self-esteem or become depressed because they don’t like to be overweight. We think it is very important that all parents help their children achieve a normal weight to prevent the diseases of obesity and allow their children to lead a normal and productive life. The time for you to get started on this is NOW. Ask us to help.
