A Study on Associations Between Multidimensional Human Phenotypic Traits and Human Growth and Development

16. oktober 2026 opdateret af: Nanfang Hospital, Southern Medical University

This observational study aims to investigate the associations between multidimensional human phenotypic characteristics and growth and developmental features. A total of 500 participants aged 6 to 60 years are planned to be enrolled. Multidimensional phenotypic characteristics will be assessed using non-invasive methods, including fingerprint imaging, foot morphology assessment, facial and tongue feature acquisition, anthropometric measurements, and musculoskeletal examinations. Development-related musculoskeletal characteristics, including plantar arch morphology, lower-limb alignment, joint range of motion, and generalized joint mobility, will also be assessed. The collected data will be analyzed to explore associations between external phenotypic characteristics and musculoskeletal growth and developmental features.

Detaljeret beskrivelse

Primary Objective:

The primary objective of this study is to investigate the associations between multidimensional human phenotypic characteristics and musculoskeletal growth and developmental features. Multidimensional phenotypic data will be collected using non-invasive assessment methods. Fingerprint characteristics will be obtained using high-resolution fingerprint imaging and characterized according to dermatoglyphic patterns and quantitative features. Foot morphology and plantar arch characteristics will be assessed using three-dimensional foot scanning. Facial and tongue features will be acquired using standardized digital imaging methods. Anthropometric characteristics and joint range of motion will also be measured using standardized procedures.

Musculoskeletal growth and developmental characteristics will be evaluated through physical examination and quantitative measurements. These assessments will include plantar arch morphology, lower-limb alignment, joint range of motion, and generalized joint mobility assessed using the Beighton score. Associations between multidimensional phenotypic characteristics and these musculoskeletal developmental features will be examined using appropriate statistical methods.

Secondary Objective:

The secondary objective is to explore whether combinations of multidimensional phenotypic characteristics are associated with specific patterns of musculoskeletal growth and development. The study will integrate fingerprint, foot, facial and tongue, anthropometric, and musculoskeletal data to investigate potential relationships among different phenotypic dimensions. Exploratory multivariable and machine-learning analyses may be used to identify combinations of phenotypic features associated with musculoskeletal developmental characteristics.

Kohorter og interventioner

Gruppe / kohorte
Intervention / Behandling
Adult Group

Adult participants aged 18 to 60 years who undergo multidimensional phenotypic assessments, including fingerprint imaging, foot morphology assessment, facial and tongue feature acquisition, anthropometric measurements, joint range of motion assessment, and evaluation of generalized joint mobility and other musculoskeletal developmental characteristics.

Fingerprint images of all ten fingers will be collected using a high-resolution fingerprint scanner. Dermatoglyphic characteristics, including fingerprint pattern types (arch, loop, and whorl), total ridge counts, and ridge counts of individual fingers, will be quantitatively and qualitatively assessed. These naturally occurring phenotypic characteristics are observed and measured only, with no intervention assigned to participants.

Minor Group

Participants aged 6 to 17 years who undergo multidimensional phenotypic assessments, including fingerprint imaging, foot morphology assessment, facial and tongue feature acquisition, anthropometric measurements, joint range of motion assessment, and evaluation of generalized joint mobility and other musculoskeletal developmental characteristics.

Fingerprint images of all ten fingers will be collected using a high-resolution fingerprint scanner. Dermatoglyphic characteristics, including fingerprint pattern types (arch, loop, and whorl), total ridge counts, and ridge counts of individual fingers, will be quantitatively and qualitatively assessed. These naturally occurring phenotypic characteristics are observed and measured only, with no intervention assigned to participants.

Foranstaltningsbeskrivelse
Tidsramme
Foot Arch Morphology Assessed by Arch Index
Tidsramme: Baseline

Foot arch morphology will be assessed using the Arch Index derived from standardized foot measurements. The Arch Index will be used as a quantitative indicator of plantar arch morphology to characterize variations in foot development among participants.

Baseline
Generalized Joint Hypermobility Assessed by Beighton Score
Tidsramme: Baseline

Generalized joint hypermobility will be assessed using the 9-point Beighton scoring system. The total score ranges from 0 to 9, with higher scores indicating greater generalized joint hypermobility.

Tidsramme
Anthropometric and Limb Proportional Measurements
Tidsramme: Baseline

Anthropometric measurements, including height, body weight, upper- and lower-limb lengths, and other relevant body dimensions, will be collected using standardized measurement procedures. Limb proportional indices will be calculated to characterize individual differences in body and limb morphology.

Baseline
Foot Morphological Characteristics
Tidsramme: Baseline

Foot morphological characteristics will be assessed using standardized foot scanning and measurement procedures. Measures will include foot dimensions and morphological features derived from plantar and foot-shape data to characterize individual variations in foot morphology.

Baseline
Fingerprint Dermatoglyphic Characteristics
Tidsramme: Baseline

Fingerprint images will be collected using a standardized acquisition procedure. Dermatoglyphic characteristics, including fingerprint pattern types and other morphological features, will be extracted and analyzed to investigate their associations with foot morphology, limb proportions, and generalized joint hypermobility.

Baseline
