| Summary: | Grip strength indicates the description of the status and general muscle strength of
hand and overall upper extremity strength. It is an important measure used to evaluate
outcomes of treatment after injured hands. Currently, there are not any established
local data regarding grip strength norms. As such, these norms should be developed
for various nationalities living in the same or different geographical region. The aim
of the present study is to determine the hand grip and pinch strengths and its associated
factors among Malaysian students in Universiti Putra Malaysia.
A cross-sectional study using multistage random sampling was carried out among
Malaysian students aged 18-29 years in Universiti Putra Malaysia from November
2017 until April 2018. The sample size was 848 respondents based on two group mean
comparison formula. Data was collected using Structured questionnaire on
sociodemographic characteristics, medical history, lifestyle practices, and
measurements, including anthropometry and handgrip strength were taken. Data
collected coded and analyzed using IBM SPSS software. Data was analyzed using
descriptive and analytical statistics. Pearson correlation test was used to examine the
relationship between hand grip strength and pinch grip strength.
The results show that the overall response rate was 94% . Majority of the respondents
were Malays (81.6%) followed by Chinese (12.4%) and finally Indian (6%). The
overall mean age was 21.05 ±sd= 1.79 years and ranged between 18 and 29 years. The
overall mean hand grip strength (HGS) was 18.32 (±sd=5.99) kg and ranged between
8.17 to 41.0. The mean hand grip strength (HGS) for male students was 24.74
(±sd=7.66) kg and ranged between 11.50 to 41.00. While the overall mean HGS among female students was 16.94 (±sd=7.66) kg and ranged between within 8.17 to
30.67. In Conclusion there was a significant relationship between hand grip strength
and socio-demographic characteristics (age, gender, ethnicity, BMI and hand
dominance). There was a significant association between BMI and pinch grip strength
in terms of (KP, PP, TP) in both right and left hands. Gender, BMI, ethnicity and age
are predictor factors that affecting hand grip strength. Three predictor factors which
are gender, BMI and ethnicity were affecting key pinch and palmar pinch strengths.
While only two predictors factors which are gender and BMI were affecting tip pinch.
