To examine factors associated with change in grip strength.
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.
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.
Results can be used to design interventions to improve strength outcomes.
研究与握力变化相关的因素。
在基线和 3 年后测量握力。变化分为“下降>/=5 公斤”、“增加>/=5 公斤”和“无变化”，并使用多项多变量逻辑回归进行分析。
男性、报告患有心血管疾病、工具性日常生活活动受限、下肢功能受限、舒张压较高、体力活动较高和体重较大的人，握力下降的可能性更大。曾有医疗补助、日常生活活动能力基本残疾和因费用而无法在过去一年看医生的人，下降的可能性较小。握力增加更可能发生在男性和有工具性日常生活活动障碍、下肢功能受限、舒张压高和体力活动较高的人身上；年龄较大的参与者则不太可能出现这种情况。
结果可用于设计干预措施以改善力量结果。
