Insights
This study established normative handgrip strength values for Colombian youth aged 6-17. Males exhibited higher handgrip strength than females, with strength increasing with age in both sexes.
Area of Science:
- Pediatric physical assessment
- Biostatistics
- Human physiology
Background:
- Establishing normative data for physical parameters like handgrip strength is crucial for assessing child and adolescent development.
- Previous studies have shown sex and age-related differences in handgrip strength, but country-specific data are often lacking.
Purpose of the Study:
- To determine sex- and age-specific normative values for handgrip strength and relative handgrip strength in Colombian children and adolescents (6-17 years).
- To compare these normative values with those reported in international studies.
Main Methods:
- Cross-sectional analysis of 2647 Colombian children and adolescents.
- Handgrip strength measured using a digital dynamometer; relative handgrip strength calculated based on body weight.
- Quantile regression models used to estimate percentiles (P5-P95) for normative values, stratified by sex.
Main Results:
- Handgrip strength values were significantly higher in males compared to females across all age groups.
- Handgrip strength increased with age in both sexes.
- Relative handgrip strength showed a proportional increase with age in males, but not in females.
Conclusions:
- This study provides essential normative data for handgrip strength in Colombian youth.
- Observed differences in handgrip strength between sexes and its relationship with age are consistent with general physiological trends.
- Variability in methodologies across international studies may explain discrepancies in reported handgrip strength values.
Objective:
The objective of this study is twofold: i) to estimate the normative values for handgrip strength and relative handgrip strength, specific to sex and age, for Colombian children and adolescents from 6 to 17 years of age using quantile regression models and ii) to compare the normative values for handgrip strength and relative handgrip strength in Colombian children and adolescents with those in children and adolescents in different countries.
Method:
This was a cross-sectional analysis of a sample of 2647 youngsters. Handgrip strength was evaluated with a TKK 5101 digital dynamometer (Takei Scientific Instruments Co., Ltd., Tokyo, Japan). The relative handgrip strength was estimated according to weight in kilograms. The normative values were estimated to handgrip strength and relative handgrip strength through quantile regression models for the percentiles P5, P10, P25, P50, P75, P90, and P95 developed independently for each sex. All analyses were adjusted for the expansion factor.
Results:
The values for handgrip strength were considerably higher in males than in females in all age ranges. Additionally, as age increased for both sexes, the values for handgrip strength increased. The percentiles by sex and age for relative handgrip strength show for males a proportional increase according to age; for females, this did not occur.
Conclusions:
When making comparisons with international studies, variability is observed in the methodologies used to evaluate handgrip strength and estimation methods, which could influence the discrepancies between the different reports.
