Summary
Identifying distinct weight change patterns in adults can guide personalized interventions. Higher adherence to behavioral sessions and physical activity correlates with successful long-term weight management.
Area of Science:
- Obesity Research
- Behavioral Science
- Weight Management
Background:
- Understanding weight change dynamics is crucial for developing effective, long-term weight loss strategies.
- Personalized interventions may improve outcomes for overweight and obese individuals.
Purpose of the Study:
- To identify distinct weight change patterns over 18 months in adults with overweight/obesity.
- To examine participant characteristics and intervention adherence factors linked to these patterns.
Main Methods:
- A sample of 359 overweight/obese adults participated in a weight loss (0-6 months) and maintenance (7-18 months) intervention.
- Weight loss involved reduced energy intake and increased physical activity (PA); maintenance focused on energy balance and continued PA.
- Latent profile analysis was used to identify weight change patterns.
Main Results:
- Three distinct weight change profiles were identified.
- Participants in successful weight loss profiles (∼14% loss) demonstrated higher attendance at behavioral sessions and increased PA.
- Higher self-efficacy for weight management and exercise barriers were observed in successful weight loss profiles.
Conclusions:
- Weight change patterns are identifiable in overweight/obese adults undergoing intervention.
- These patterns are significantly associated with individual characteristics and adherence to intervention components like behavioral sessions and physical activity.

13.7K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

01:24Obesity
1.5K
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...

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...
