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 adipocytes...

Health Information Technology (HIT)
Health Information Technology, commonly called HIT, integrates advanced information systems and technology in healthcare settings. Its primary functions include:

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...

Background:

Overweight individuals in the US Air Force face health risks.
Behavioral Internet Treatment (BIT) offers a scalable approach to weight management.
Comparing BIT with usual care (UC) is crucial for evidence-based interventions.

Purpose of the Study:

To evaluate the cost-effectiveness of a BIT program for weight management.
To compare BIT with usual care (UC) in a diverse sample of overweight US Air Force adults.
To assess the impact of BIT on weight, body fat, waist circumference, and lifestyle confidence.

Main Methods:

A two-group parallel randomized controlled trial was conducted.
Participants were randomized to either UC or UC plus BIT.
Primary outcomes included changes in body weight, body fat, and waist circumference, analyzed using an incremental cost-effectiveness analysis (ICEA).

Main Results:

The BIT intervention cost $49.24 per participant, with staff-time costs at $14.03 per participant.
Cost per kilogram of weight loss was $25.92, and per centimeter of waist circumference loss was $28.96.
Each point increase on the Weight Efficacy Lifestyle (WEL) subscale cost $37.88, indicating improved confidence in managing eating triggers.

Conclusions:

Behavioral Internet Treatment (BIT) is a cost-effective strategy for weight management in the US Air Force.
While initial investment is higher, BIT leads to significant long-term cost savings.
Internet-based behavioral interventions represent a valuable tool for preventive healthcare, enhancing both individual and public health.
