Shaping Behaviour and Attitude in Childhood Obesity

Introduction

{{subst:Introduction}}

Background:

The negative health consequences experienced by overweight and obese children are wide ranging and include an increased risk of hypertension, type 2 diabetes and asthma. Children's mental wellbeing has also been shown to be negatively affected by overweight and obesity. The health risks of an unhealthy weight in childhood continue into adulthood and can result in an increased risk of conditions in life including cardiovascular disease..................

Epidemiology: 

The Scottish Health Survey 2011 reports that;

• 65.6% of children aged 2-15 had a healthy weight, a small decrease from 70.3% in 1998.
• 31.6% of children were overweight or obese, a slight increase since 1998 when the prevalence was 28.0%.
• 15.7% of children were obese or morbidly obese, representing a small rise in prevalence from 13.0% in 1998.
  
• Boys were significantly less likely than girls to be a healthy weight (65.1% compared with 69.8%) and were more likely to be overweight or obese (32.7% compared with 28.0%).
• Healthy weight prevalence was significantly associated with age though not in a linear fashion. Prevalence was generally highest in the early years (aged 2-7) and was lowest among boys aged 10-11 (56.6%) and girls aged 12-13 (62.9%).
• Boys aged 10-11 and girls aged 12-13 had the highest prevalence of overweight or obesity (41.9% and 33.4%, respectively).
• There is a strong association between parental BMI and child BMI. Children with parents who are either a healthy weight or underweight are less likely to be overweight or obese than children of obese parents (21.0% compared with 40.1%).
• Boys in the lowest income households were more likely than those in other household income groups to be obese (19.7% compared with 14.2% in the highest income group). 
• Area deprivation was significantly associated with obesity. Girls and boys in the most deprived quintile were less likely to be a healthy weight and more likely to be obese than girls and boys in the least deprived areas. Children living in the 15% most deprived areas in Scotland had a significantly higher prevalence of obesity than those living elsewhere (18.7% compared with 14.5%).

Learning Outcomes

By the end of this Wiki the reader will be able to:

• Recognize demographic and psycho-social aspects underpinning childhood obesity.
• Describe theories that shape and influence behaviour and attitudes.
• To apply behavioural/attitudinal theories to effectively implement strategies to combat childhood obesity in (primary) school.
• To evaluate the effectiveness of your strategy to change the behaviours of the children.
  

Theories of Behaviour Change

Changing Attitude:

Social Cognitive Theory:

Theory of Planned Behaviour:

The theory of planned behavior (TPB) suggests that behavior is dependent on one’s intention to perform the behavior. Intention is determined by an individual’s attitude and subjective norms. 

Behavior is also determined by an individual’s perceived behavioral control, defined as an individual’s perceptions of their ability or feelings of self-efficacy to perform behavior. This relationship is typically dependent on the type of relationship and the nature of the situation.

Transtheoretical (Stages of Change) Model:
