Insights
Low threshold intervention for children with impending obesity successfully prevented BMI SDS increase. Early childhood interventions are key to preventing childhood obesity.
Area of Science:
- Pediatrics
- Public Health
- Nutrition Science
Context:
- Childhood obesity is a growing public health concern, with rapid weight gain often starting between ages 4-5.
- Early identification of children at risk is crucial for effective intervention.
Purpose:
- To investigate the effectiveness of a low-threshold prevention program in mitigating BMI SDS increase in children with impending obesity.
- To assess the impact of an age-adapted nutrition and exercise program on weight management in early childhood.
Summary:
- A study involving 365 children (ages 4-7) with impending obesity randomly assigned them to an intervention or control group.
- The intervention group, after opting in, showed stabilized BMI SDS, while the control group and non-participating intervention children experienced an increase.
- Participants in the intervention group demonstrated reduced energy intake and improved protein consumption, indicating successful dietary changes.
Impact:
- Low-threshold interventions in early childhood can effectively prevent the progression of obesity.
- This approach highlights the potential for lifestyle modifications to manage weight in at-risk children.
Background And Objective:
Obesity in children is characterized by a rapid gain of weight starting at an age of 4 to 5 years. We investigated whether low threshold prevention prevented a further increase of the Standard-Deviation-Score of the BMI (BMI SDS) in children with impending obesity.
Patients And Methods:
The network CrescNet collected data from more than 300,000 children. We selected 365 children with impending obesity (age 4 to 7 years). After randomisation the study population was divided into an intervention group (180 children) and a control group (185 not informed children). The paediatrician carried out a low threshold intervention consisted of an age-adapted nutrition and exercise program to inspire the awareness of the adequate nourishment and motion.
Results:
59 children of the intervention group opted for a participation and 49 of them took part to the end of the study. This study population stabilized their BMI SDS (p < 0.025). The children randomised in the intervention group who were not interested to participate, and the children of the control group increased their BMI SDS within the observation period of one year (p < 0.001, p = 0.002). According to nutrition diaries a decrease energy intake of the participants of the intervention group was detected. The percentage of protein intake was particularly remarkable, amounting to 363 % fulfillment of demand at the beginning of the study and 274 % at the end. A regression analysis suggests that an intervention and also the approval to take part in the study had a significant influence on changes in BMI SDS.
Conclusion:
A low threshold intervention in early childhood could successfully prevent an increase of obesity.
