BACKGROUND & AIMS: Cystic Fibrosis (CF) may impact nutritional status. Handgrip strength (HGS) may be used for nutrition assessment. The objective of the study was to evaluate changes in HGS over time in children with CF compared to children without CF. A secondary purpose was to analyze the relationship of clinical characteristics of CF with HGS.
METHODS: A prospective, longitudinal study was conducted. The non-CF group (n = 76) was recruited from a school and the CF group (n = 75) from an accredited CF center. Height, weight, mid-upper arm circumference, triceps skinfold, and HGS were measured at baseline and approximately three and six months in both groups. Data for pulmonary function, nutrition risk, enteral supplementation, CF transmembrane conductance regulator modulator, steroids, antibiotics, vitamin levels, CF related diabetes (CFRD), and recent hospitalization were collected for the CF group. A mixed model determined the difference in the change in HGS between the CF group and the non-CF group. For all analyses, p=<0.05 was significant.
RESULTS: The rate of change in HGS z-score in the CF-group (0.18 ± 0.05) versus the non-CF group (0.06 ± 0.06) was not significant (p = 0.15). Initial mean dominant HGS z-score was significantly lower (p = 0.02) in those with vitamin D deficiency (-1.35 ± 0.09) versus those without (-1.02 ± 0.11). HGS z-score significantly (p = 0.02) decreased over time in children with CFRD (-0.19 ± 0.22) versus children without CFRD (0.32 ± 0.14), p = 0.02.
CONCLUSION: Serial measurements of HGS may help detect changes in muscle function related to CFRD and vitamin D deficiency. Further investigation is warranted to elucidate HGS's role in nutrition assessment of children with CF.
