    A Cross-Sectional Comparison of Incisive Biting Force and Grip Strength in Males and Females Ages 10 to 24
    (1971) Harrington, John Fulton
    A cross-sectional study involving 150 subjects, both male and female, ages 10 to 24, was made to see if there was a correlation between grip strength and incisal biting force considering other variables such as age, sex, handedness, height and weight. The Collins Grip Strength Dynamometer was used to test the incisal bite force. A nonstatistical comparison was made with other investigators' reports of grip strength versus age and a similarity in results was noted between this sample and previous samples. Correlation coefficients (r) between all of the independent variables, except for handedness, and the incisal bite force were found to be significant at P = .01. When the stepwise regression analysis was used, only the squared term of right-hand grip was found to be significant and the rest of the independent variables were eliminated showing a curvilinear relation of right-hand grip with bite force. An R value of 0.494 and an RSQ of 0.244 were derived for the square of right grip. This means that one-fourth of the variation in incisal force was due to right-hand grip. Clinically this is not significant. Further investigations using larger samples might shed a great deal of light on this relationship or it might prove to be unique to this sample.

    A Study of the Correlation of Incisive Force with Hand Grip Strength, Height, and Weight in Adult Males
    (1972) Kamisugi, Arthur Tadao
    Incisive force in a sample of 76 adult white males was tested for correlation with grip strength, height, and weight. A cantilever beam intraoral force transducer connected to a Techni-Rite Recorder with an SST Conditioner recorded the incisive forces. Grip strength was measured by the Collins Grip Test Dynamometer #70113-060. Correlation coefficients "r" and a stepwise regression analysis revealed that the independent variables were not of predictive value in determining incisive force for this sample. Height and weight were significant at the .01 level, and grip strength and weight were significant at the .05 level. The author believes that incisive force cannot be predicted by general body development characteristics, and that the limiting parameter of obtaining maximum biting force levels is the subject's emotional state of fear of pain and injury.

    Hand Grip Strength and Body Composition in HIV-Infected Rural Kenyan Women
    (2012-04-23) Ernst, Judith A.; Ettyang, Grace; Johnson, Cynthia; Nyandiko, Winstone; Siika, Abraham; Neumann, Charlotte
    To determine if meat in the diets of HIV infected rural Kenyan women prevents the loss of strength and body mass in those not yet ill enough to warrant antiretroviral drugs.

    Predictors of change in grip strength over 3 years in the African American health project
    (Sage Publications, 2010-03) Miller, Douglas K.; Malmstrom, Theodore K.; Miller, J. Philip; Andresen, Elena M.; Schootman, Mario; Wolinsky, Fredric D.; Department of Medicine, IU School of Medicine
    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.
