Relations Between Protein Energy Intake, Micronutrient Intake, and the Grip Strength of Elderly Women

Background: Handgrip strength is one of the measurements and assessments of muscle function. It is essential to maintain muscle strength to keep mobility and productivity. The decrease of this muscle function is caused by many factors including nutritional status, nutrient intake, and physical activity. Aim: This research aims to analyze the relations of protein-energy intake, micronutrient intake (calcium, iron, zinc), and the grip strength of elderly women. Settings and Design: This study uses a cross-sectional study design with a sample of 65 respondents.Samples were selected with purposive sampling technique. The samples in this study were obtained from elderly women in the work area of the Poris Gaga Lama Health Center, Tangerang City, Banten. Methods and Material:. Data of protein and energy intake were obtained using 2x24h food recall form, and data of micronutrient intake was taken using SQ-FFQ form. Hand grip strength was taken with a digital handgrip dynamometer. Statistical analysis used: Pearson and Spearman correlation test. Results: The results of the analysis of protein energy intake as well as the micronutrient intake of respondents were mostly sufficient based onthe recommended nutritional adequacy rate for elderly women. There were relations between energy intake (p= 0.0001, r=0.75), protein intake (p=0.0001, r=0.80), calcium intake (p=0.0001, r=0.74), iron intake (p=0.0001, r=0.62), and zinc intake (p=0.0001, r= 0.77) as well as the grip strength. Conclusions: There are relations between protein energy intake, micronutrient intake and the grip strength of the elderly. The elderly are advised to consume macronutrients such as protein energy and micronutrients to increase muscle mass.
