Recognition and discrimination of the heaviness of a lifted object.

Individuals' concept of their own bodies.

A person's view of himself.

The mass or quantity of heaviness of an individual. It is expressed by units of pounds or kilograms.

A state of insufficient flesh on the body usually defined as having a body weight less than skeletal and physical standards. Depending on age, sex, and genetic background, a BODY MASS INDEX of less than 18.5 is considered as underweight.

A status with BODY WEIGHT that is above certain standard of acceptable or desirable weight. In the scale of BODY MASS INDEX, overweight is defined as having a BMI of 25.0-29.9 kg/m2. Overweight may or may not be due to increases in body fat (ADIPOSE TISSUE), hence overweight does not equal "over fat".

The process by which the nature and meaning of sensory stimuli are recognized and interpreted.

A status with BODY WEIGHT that is grossly above the acceptable or desirable weight, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).

An indicator of body density as determined by the relationship of BODY WEIGHT to BODY HEIGHT. BMI=weight (kg)/height squared (m2). BMI correlates with body fat (ADIPOSE TISSUE). Their relationship varies with age and gender. For adults, BMI falls into these categories: below 18.5 (underweight); 18.5-24.9 (normal); 25.0-29.9 (overweight); 30.0 and above (obese).

Any observable response or action of an adolescent.

Maleness or femaleness as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or effect of a circumstance.

Decrease in existing BODY WEIGHT.

Increase in BODY WEIGHT over existing weight.

The selecting and organizing of visual stimuli based on the individual's past experience.

The real or apparent movement of objects through the visual field.

The perceiving of attributes, characteristics, and behaviors of one's associates or social groups.

The process whereby an utterance is decoded into a representation in terms of linguistic units (sequences of phonetic segments which combine to form lexical and grammatical morphemes).

The sum of the weight of all the atoms in a molecule.

The mass or quantity of heaviness of an individual at BIRTH. It is expressed by units of pounds or kilograms.

Perception of three-dimensionality.

The process whereby auditory stimuli are selected, organized, and interpreted by the organism.

The sensory discrimination of a pattern shape or outline.

The process by which PAIN is recognized and interpreted by the brain.

The ability to estimate periods of time lapsed or duration of time.
