Abstract Introduction. Grip strength (GS) is an appealing measure mainly considered for sarcopenia/disability screening in lieu of other complex lower-extremity function measures directly reflective of the disability causal pathway (e.g., Short Physical Performance Battery [SPPB]). Contexts in which GS may be clinically useful above and beyond SPPB scores remain to be characterized. We examined the association of GS with incident ADL disability independently from SPPB. Methods. Prospective study using Rounds 1 and 4 data from the National Health and Aging Trends Study, which enrolled a U.S. representative sample of Medicare beneficiaries 65 years and older. Nursing home subjects were excluded. Logistic regression estimated the odds of incident need for help in ADLs 3 years later as a function of both baseline GS and SPPB. Results. Lower GS and SPPB scores were both independently associated with incident ADL dependence, as estimated by gender-stratified models including both GS and SPPB, and controlling for demographics, diseases, weight, and previous hospitalization. Per 3 kg higher GS, the adjusted odds of incident ADL dependence incrementally decreased 19.2% (95% CI: 11.5%–26.2%, p<0.001) in women, and 12.5% (95% CI: 6.7%–17.8%, p<0.001). No effect modification by prevalent ADL difficulty or age at baseline was observed. Conclusion. Low GS might adversely impact ADL dependence risk above and beyond the effect of lower-extremity functioning captured by SPPB. Research assessing the extent to which ADL dependence prevention could be enhanced by intervention strategies concomitantly targeting lower- and upper-extremity function, and using SPPB and GS as tracking outcomes measures is warranted.
