Body mass index is a value derived from the mass and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is universally expressed in units of kg/m², resulting from mass in kilograms and height in metres. https://en.m.wikipedia.org/wiki/Body_mass_index

Sir, it's better we first define "socio-demographic indicators"!

Socio-demographics are nothing more than distiquishing characteristics of a population which are reflection or distribution of their social life, sex, culture, also average physical or health or development features. Generally, characteristics such as age, gender, ethnicity, education level, average height, years of experience, location, etc. are being considered as socio-demographics indicators.

A large and growing body of evidence and research shows that sociodemographic factors such as Age, BMI, Location, Access to healthcare and Language, and socioeconomic status (SES), such as income and education, can influence choice of health related activities, health outcomes, health-related quality of life (HRQL) and utility values. For example, BMI can determine quality of life and health, frequency to health care centres and some interventions, and choices of purchase and partners(friends and spouses) :) why not?

Thank you so much for this helpful contribution@Ibiloye

To specifically answer your question, no it's not a socio-demographic indicator. Its an anthropometric indicator. That is, its a value used in the scientific study of the measurements and proportions of the human body. The determinants of that anthropometric outcome are many, including genetic, environmental and a range of socil-demographic indicators like education, wealth, sex, etc.

Body Mass Index is a simple calculation using a person's height and weight. The formula is BMI = kg/m2 where kg is a person's weight in kilograms and m2 is their height in metres squared. A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9. https://www.diabetes.ca/managing-my-diabetes/tools---resources/body-mass-index-(bmi)-calculator

no it is not a socio-demographic feature nut rather a factor of an individual's height and weight as Chinaza Godswill Awuchi explained

BMI is an anthropometric indicator which includes weight and height of the individual. It can't be used as a socio demographic indicator.

Anthropometric indicator for nutritional status

Body mass index is an anthropometric index used to ascertain nutritional status and as such it is not a socio-demographic index.

To justify our answer to this question, we first need to understand what socio-demographics refers and the scope. But surprisingly, little attention have been given to establish a clear conceptual and theoretical meaning of socio-demographics.

However, a recent work of Abdullahi (2020) proposed that:

"Socio-demographics describe the relationship that exists between individuals, or groups of individuals and their attained socio-demographic statuses (socio-demographic positions and successes) in a given population over a given period. Socio demographic statuses are common, universal, and desirable positions, achievements, and advantages every individual strives and competes to attain, achieve, maintain, and upgrade which are influenced by the biological and social environments, driven and regulated by a continuum of competitions (through genetic competition, physiological competition, demographic competition, psychosocial competition) and selectively evolved through the mechanism of genetic selection, physiological selection, demographic selection, psychosocial selection, and resultant psychosocial fitness and socio-demographic evolution".

Reference:

Abdullahi, K.B. Socio-Demographic Statuses: Theory, Methods, and Applications. Preprints 2019, 2019020051 (doi: 10.20944/preprints201902.0051.v2).

Looking at this definition, we ask ourselves one question. Does BMI a premise of competition and natural selection? And how common, universal, and desirable is it to individuals in a population?

If yes and it satisfy the universality and commonality characteristics of the individuals in the population, then it is considered among the sociodemographic chacteristics. I guess it isn't, but a an anthropometric index as other colleagues have responded.

One thing I can add about the relationship of BMI with socio-demographics is: In clinical studies, BMI (the measure of nutritional status) can be related to the socio-demographics of individuals.

I hope this can help or ignite further criticism.

Thank you.

Reference man is between 18-29 years of age and weighs 60 kg with a height of 1.73m with a BMI of 20.3 and is free from disease and physically fit for active work; on each working day, he is engaged in 8 hours of occupation which usually involves moderate activity, while when not at work he spends 8 hours in bed, 4-6 hours in sitting and moving about, 2 hours in walking and in active recreation or household duties.

Reference woman is between 18-29 years of age, non-pregnant non- lactating (NPNL) and weighs 55 kg with a height of 1.61m and a BMI of 21.2, is free from disease and physically fit for active work; on each working day she is engaged in 8 hours of occupation which usually involves moderate activity, while when not at work she spends 8 hours in bed, 4-6 hours in sitting and moving about, 2 hours in walking and in active recreation or household duties.

The anthropometric values for the age group 18-29 y for both genders. The reference body weights employed for computing the revised RDA are given in Table 3.3. The method adopted for computing reference body weights for different age categories is as follows:

Infants

The Committee decided to retain the approach adopted by the previous committee and used the average of birth weight and body weight at 6 months for computing the reference body weights of infants (0-6 months). For 6-12 months, an average of body weights at 6 months and at 12 months was adopted.

Children

For children 1-3y, an average of bodyweight at 18 m, 30 m and 42 m of WHO/MGRS median weights was taken.

Since WHO/MGRS data covers till the age group of 1-5 y, and the age category for computing RDA is 4-6y, it was decided to obtain the body weights from NNMB/India Nutrition Profile data from 4-6 y onwards. Therefore, for children of 4-6 y an average of 4+, 5+and 6+ and similarly for other age groups were obtained from the 95th centile values of body weights of rural India.

Adults

The average of age category of 18-19, 20-24 and 25-29 years was used for computing the reference body weights for adult man and woman.
