Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but children taking medication that affects appetite or attention are excluded from participating.

What data supports the effectiveness of the treatment Attentional bias to food cues for childhood obesity?

Research suggests that children with obesity have a stronger attention bias towards food, similar to adults with obesity. This indicates that addressing attentional biases could be a useful part of obesity treatment, although a pilot study found that training to reduce this bias was not effective in maintaining weight loss in obese children.12345

Is the treatment of attentional bias to food cues safe for humans?

The research does not provide specific safety data for the treatment of attentional bias to food cues, but it does not report any adverse effects or safety concerns in the studies conducted.26789

How does the treatment for parental feeding practices for childhood obesity differ from other treatments?

This treatment focuses on modifying parental feeding practices to address childhood obesity, which is unique compared to other treatments that may focus on diet, exercise, or medication. It targets the underlying behavioral aspects of feeding, aiming to change how parents influence their children's eating habits, rather than directly altering the child's diet or physical activity.2571011

What is the purpose of this trial?

The preschool years (2-5 years of age) is a critical timeframe to shape the lifetime risk of obesity. While the causes of obesity are complex, appetitive traits related to overeating, such as high food approach and low food avoidance, are robustly associated with a greater BMI among children. Some children are genetically pre-disposed to expressing obesogenic appetitive traits, and those traits may mediate a genetic risk for obesity. Separately, parental feeding practices are emerging as an important, yet modifiable, influence on children's obesity risk. Coercive control feeding practices, such as strictly limiting a child's intake of highly palatable foods (restriction) and using food to control children's negative emotions (emotional feeding), are believed to be detrimental for young children because they impede self-regulatory skills around eating and may increase the saliency of highly palatable foods. The goal for this project is to disentangle the inter-relationships between coercive control feeding practices, children's obesogenic appetitive traits, and children's dietary intake across the preschool years to understand how coercive control feeding practices ultimately impact children's adiposity gain over time. Importantly, the investigators aim to understand how those effects differ based on children's underlying genetic risk for obesity. The investigators hypothesize that parents will respond to children's obesogenic appetitive traits by exhibiting more coercive control feeding practices (restriction, emotional feeding), which in turn, will promote future increase in obesogenic appetitive traits and overconsumption, leading to excess adiposity gain among children. Importantly, the investigators hypothesize children with a high genetic risk for obesity will be most susceptible to the negative effects of coercive control feeding practices because food is highly salient for them. The investigators will test the hypotheses among a cohort of children aged 2.5 years old using a longitudinal study design with repeated assessments every 6 months until children are 5 years old. If successful, study findings may be leveraged to develop tailored strategies to help parents support healthy eating behaviors among their young children that consider the heterogeneity in obesogenic appetitive traits among young children due to genetic risk factors.

Eligibility Criteria

This trial is for children aged 2.5 to 5 years who may be at risk of obesity due to genetic factors and certain eating behaviors. It focuses on understanding how parents' feeding practices influence their child's weight gain over time, especially in those with a high genetic predisposition for obesity.

Inclusion Criteria

My child is between 2 years 3 months and 2 years 11 months old with normal or corrected vision.

Exclusion Criteria

I do not have food allergies, dietary restrictions, take medication that affects my appetite or attention, and no relatives are in this study.

Treatment Details

Interventions

  • Attentional bias to food cues
Trial Overview The study examines the relationship between parental feeding methods, like restricting food or using it as an emotional tool, and children's appetitive traits that can lead to overeating. The goal is to see how these factors contribute to childhood obesity, particularly in genetically susceptible kids.

Findings from Research

A study involving interviews and diaries from 22 mothers of healthy weight children aged 3-5 revealed that parental feeding behaviors are primarily motivated by practical and health considerations rather than concerns about weight.
Parents demonstrated a variety of feeding strategies, including promoting or restricting food intake and responding to their children's individual appetitive traits, suggesting that obesity prevention efforts should align with parents' motivations and focus on their children's unique characteristics.

A study involving 50 children (25 overweight and 25 healthy-weight) aged 8-12 years found that both groups initially orient towards food stimuli, but overweight children continue to show a preference for food images during longer attention spans (500 ms and 1500 ms).
This suggests that while all children may initially notice food cues, overweight children have a sustained attentional bias towards food, indicating a potential mechanism that could contribute to the risk of obesity later in life.

A training program aimed at improving cognitive control over unhealthy food choices was found to be feasible and acceptable for 36 obese youngsters aged 9-15 years in an inpatient treatment program.
However, the preliminary results indicated that the cognitive training tasks did not effectively help these children in maintaining weight loss after treatment, suggesting a need for further research to improve intervention strategies.
