Abstract

Objective:

To obtain expert feedback on a public health messaging campaign to reduce caloric intake in US adults.

Design And Setting:

In 2018, researchers conducted semistructured telephone interviews with US-based experts in obesity prevention, mental health, and health communications.

Participants:

The research team invited 100 experts to participate using purposive and snowball sampling techniques. Of those invited, 60 completed interviews, among which 37 (62%) were obesity prevention experts, 12 (20%) were mental health experts, and 11 (18%) were health communications experts.

Main Outcome Measure:

Expert feedback regarding a public health messaging campaign to reduce caloric intake.

Analysis:

Two researchers reviewed and coded all transcripts. The team identified major themes and summarized findings.

Results:

Most experts identified barriers to effective calorie reduction including social and environmental factors, lack of actionable strategies, and confusion regarding healthy eating messages. Expert suggestions for effective messaging included addressing eating patterns, emphasizing nutrient density, and dissemination through multiple channels and trusted sources. In general, mental health experts more frequently voiced concerns regarding eating disorders, and communications experts raised issues regarding the dissemination of campaigns.

Conclusions And Implications:

Professionals should identify and address barriers to delivering a calorie reduction campaign before implementation, using strategies that enhance delivery to ensure an effective campaign.

Keywords:

Regulation of Food Intake

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Health Literacy

Health Literacy

Health literacy is an individual's or a community's capacity to comprehend, receive, read, and use relevant healthcare information and services. The World Health Organization (WHO, 2018) defines health literacy as the cognitive and social skills that determine the ability of individuals to gain access to, understand, and use information in ways that promote and maintain good health. As a result, the WHO helps individuals manage long-term health concerns, participate in preventative...

Energy Balance

Energy Balance

The human body gets energy from the three macronutrients: carbohydrates, proteins, and fats. Energy is released when the chemical bonds in the organic compounds present in the food are broken down. The energy content of food is measured in kilocalories (kcal), defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. This value is determined by measuring the temperature change of the water surrounding a calorimeter after the complete...

Obesity

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Models of Health Promotion and Illness Prevention II

Models of Health Promotion and Illness Prevention II

The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
The agent-host-environment model states that disease results...

Levels of Health Promotion and Illness Prevention

Levels of Health Promotion and Illness Prevention

Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...
