چکیده
conclusions the current study revealed that a significant difference existed in hgs among the low, medium, and high bmi groups. a positive correlation existed between hgs and weight and height, while sex was the most significant factor affecting hgs. these findings can serve as a reference to assess hgs prediction, whereby the sex effect should be considered. results the results showed that there were significant differences in hgs (26.80 ± 5.83, 34.55 ± 7.84, and 42.30 ± 5.35 kgf; p < 0.001) among low, medium, and high bmi subjects, respectively. however, in this study ancova was based on the covariance of sex; the three groups did not show major variations in rhgs and l-rhgs (p > 0.05). weight and height strongly correlated with hgs for hands (correlation (r) ranged from 0.000 - 0.775). regression analysis showed that when using sex and bmi as independent variables for predicting the dependent variable hgs, the coefficient of the determinant r2 was 0.753 (p < 0.001). background hand grip strength (hgs) is a predictor of upper extremity function and changes in muscle strength, physical movement and ability to undertake activities of daily living. body mass index (bmi) is a critical indicator of physical health; however, the relationship between hgs and bmi has not yet been thoroughly examined. objectives the current study aims to compare hgs in low, medium, and high bmi males and females in both hands, and also investigates the correlation between hgs and anthropometric characteristics among the three bmi groups. patients and methods the study included 200 participants who were divided into three groups based on their bmi (60 low, 58 medium, and 82 high). hgs was assessed using a hand-held jamar dynamometer. bmi was assessed by an electric body-weight height analysis machine. data was analyzed using descriptive and inferential statistics at p < 0.05.

hand grip strength in pregnant and non-pregnant females
conclusions the current study revealed that pregnant females had significantly lower hgs compared with non-pregnant ones. high parity and gravidity and later stage of pregnancy led to significantly lower hgs. higher level of adiposity led to poorer performance of hgs in females. it is recommended to evaluate hgs in antenatal care, which may have diagnostic and prognostic benefits. background ha...

Hand Grip Strength and Myocardial Oxygen Consumption Index among Coronary Artery Bypass Grafting Patients
Background: Hand grip strength (HGS) is a reliable indicator of peripheral muscle strength. Although, numerous studies have investigated the strength of hand grip; little attention has been given to coronary artery disease (CAD) patients, exploring the relationship between HGS and myocardial oxygen consumption (MVO2) index. The current study aimed to evaluate the interaction between HGS and MVO...
متن کاملThe Relationship between Acne Severity and Body Mass Index in Females
Introduction: Acne is one of the most common diseases in dermatology. It has been claimed that acne and weight gain are clinical markers of hyperandrogenism, and it seems that obesity is associated with increased responsiveness to androgenic hormones and acne severity. This investigation may aid in finding the possible relationship between severity of acne and Body Mass Index (BMI) in order to ...
