    Abstract
    Background: The age associated decline of muscle mass inevitably leads to declines in functional capacity. Studies have proven a relationship is evident between strength, function and compositional markers. Pinch strength is an emerging technique predicted as a tool for estimating nutritional status based on strength related to markers of composition and function. Objective: To assess if there is any relationship between pinch strength and markers of composition and function as a measure of nutritional status in healthy university students. Design: A cross sectional study was conducted with students recruited randomly. Non-evasive measures of composition (weight, height, body mass index, mid arm circumference, calf circumference, Bio electrical Impedance (BIA)) and function (pinch strength, handgrip strength and one minute sit to stand test) were carried out in each healthy participant (n=13). Results of assessments were analysed and tested for correlation with Pinch Strength. Results: With exception to calf circumference and total muscle mass from BIA scales there were no other significant correlations (p>0.05) found between pinch strength when tested with compositional markers. A strong relationship (r>-0.07) was seen between pinch strength and handgrip however no relationship was evident with the one minute sit to stand test. Further investigations with handgrip found comparable results with pinch strength tests and total muscle mass. Conclusion: For healthy university students trends have been demonstrated with pinch strength and markers of composition (ie. Calf circumference and BIA) and muscle function (ie. handgrip). This suggests that pinch strength has potential for identifying signs of nutritional impairment related to muscular declines. Key Words: Pinch Strength, Body Composition, Function, Nutrition.
