Glanz & Rimer (2005) suggested that theory helps” practitioners to interpret the findings of their research and make the leap from facts on a page to understanding the dynamic interactions between behavior and environmental context”.
The health belief model was developed by Irwin Rosenstock in 1966 and has been identified as one of the earliest and most influential models in health promotion. The model included four components: 1) Perceived susceptibility 2) perceived severity 3) perceived barriers 4) perceived cost of adhering to the proposed intervention.
The health belief model can be applied to diverse cultural and ethnic groups. For example some Latino mothers believe that the more robust their babies the healthier they are, this belief leads to child obesity and the risk of cardiovascular diseases. Using the health belief model can be useful to acknowledge the obesity as a health problem. Make Hispanic mothers understand the threat posed by the health problem, the benefits of avoiding the threat and factors influencing the decision to act.
When applying the HBM, health providers should assess whether or not the target population believe in the seriousness of the health problem and whether the believe action can reduce the threat at an acceptable cost. (Glanz K, 2002). Community level model can also be useful in promoting healthy eating pattern. They offers strategies that work in a variety of setting such as schools, community group, worksites,and governmental agencies. The involment of governmental agencies in the schools can help decreased the number of children with obesity problem by providing healthy lunch at a low cost,so low income students can afford them.
