OBJECTIVE: To examine factors associated with change in grip strength. METHOD: Grip strength was measured at baseline and 3 years later. Change was divided into "decreased >/=5 kg," "increased >/=5 kg," and "no change" and analyzed using multinomial multivariable logistic regression. RESULTS: Decline in grip strength was more likely for men, those reporting having cardiovascular disease, and those with instrumental activities of daily living, lower body functional limitations, high diastolic blood pressure, higher physical activity, and greater body mass. Decline was less likely among those ever having Medicaid, those with basic activities of daily living disabilities, and those unable to see a doctor in past year due to cost. Gain in grip strength was more likely for men and those with instrumental activities of daily living disabilities, lower body functional limitations, high diastolic blood pressure, and higher physical activity; it was less likely for older participants. DISCUSSION: Results can be used to design interventions to improve strength outcomes.

Miller et al. (2010) conducted a cohort in Change in grip strength. Baseline demographic, clinical, and functional predictors (e.g., sex, cardiovascular disease, blood pressure, functional limitations) vs. Reference categories (no change in grip strength) was evaluated on Change in grip strength over 3 years (decreased >=5 kg, increased >=5 kg, or no change). Male sex, cardiovascular disease, functional limitations, high diastolic BP, higher physical activity, and greater BMI predicted a >=5 kg grip strength decline over 3 years.
