Final answer:
The banning of sugary beverages from school vending machines by the local dental hygiene association is an example of health promotion, which is a preventive measure to enhance community health and address factors contributing to obesity. The correct option is D.
Step-by-step explanation:
The local dental hygiene association's policy change that banned sugary beverages from school vending machines is an example of health promotion. Health promotion involves initiatives that are undertaken to reduce health risks and enhance the health and well-being of communities.
The ban on sugary beverages in school vending machines is aimed at reducing the consumption of drinks that can lead to health issues such as dental caries, obesity, and Type 2 diabetes. It is a preventive measure that complements other aspects of public health approaches such as encouraging physical activity and healthy eating, which are fundamental parts of a child's education.
This action represents an effort to correct environmental factors responsible for increasing obesity rates by limiting access to high-calorie, low-nutrient products in schools.
