Obesity01:24

Obesity

356
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...

Classification of Illness01:17

Classification of Illness

7.2K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Classification of Systems-I01:26

Classification of Systems-I

164
Linearity is a system property characterized by a direct input-output relationship, combining homogeneity and additivity.
Homogeneity dictates that if an input x(t) is multiplied by a constant c, the output y(t) is multiplied by the same constant. Mathematically, this is expressed as:

Classification of Systems-II01:31

Classification of Systems-II

132
Continuous-time systems have continuous input and output signals, with time measured continuously. These systems are generally defined by differential or algebraic equations. For instance, in an RC circuit, the relationship between input and output voltage is expressed through a differential equation derived from Ohm's law and the capacitor relation,

Clearance Models: Noncompartmental Models01:17

Clearance Models: Noncompartmental Models

36
Clearance is a pharmacokinetic parameter traditionally defined by compartment models, signifying the rate at which a drug is expelled from the body. However, a noncompartmental model offers an alternative method for assessing clearance, primarily employing empirical data obtained after administering a single drug dose.
The noncompartmental approach capitalizes on extensive sampling data, correlating the volume of distribution to systemic exposure and the administered dosage. This method enables...

Aggregates Classification01:29

Aggregates Classification

295
Aggregate classification is generally based on its size, petrographic characteristics, weight, and source. Size classification ranges from coarse to fine aggregates, defined by the size of the particles. Coarse aggregates are particles that do not pass through ASTM sieve No. 4, and aggregates that pass through the sieve are fine aggregates.
Petrographic classification groups aggregates based on common mineralogical characteristics. Some of the common mineral groups found in aggregates are...

Area of Science:

  • Biomedical Informatics
  • Public Health

Background:

  • Obesity presents a significant global health challenge.
  • Accurate classification of obesity is crucial for effective public health interventions.

Purpose of the Study:

  • To evaluate machine learning models for predicting obesity classes.
  • To identify the best-performing model for obesity classification.

Main Methods:

  • Utilized a dataset of 2,111 individuals categorized into seven body mass index (BMI) groups.
  • Trained and tested classification models using demographic data (age, gender, eating habits), excluding height and weight.

Main Results:

  • Machine learning models successfully classified body mass index (BMI) based on demographic information.
  • The random forest model achieved the highest performance scores in obesity classification.

Conclusions:

  • Machine learning offers a promising approach for obesity classification.
  • These methods can enhance efforts to combat the global obesity epidemic.
