Grip strength is a measure for upper body functionality. Grip strength is known to be positively correlated with lower-extremity strength in older persons, with reported correlation coefficients between 0.47 and 0.51.1-2 Moreover, grip strength is a reliable (coefficient of variation 3-6% in older persons) 3-4 and portable muscle strength test that is very applicable in large epidemiological studies and in clinical practice. Low grip strength is a strong determinant of functional limitations later in life 5, mobility
disability 6, poor functional performance 7, and premature death.8-9
Measurement instruments in LASA
In LASA grip strength is measured each wave during the medical interview starting from wave C (LASAC161) using a grip strength dynamometer (Takei TKK 5001, Takei Scientific Instruments Co. Ltd., Tokyo, Japan). Measurements were made in duplicate for both hands. Respondents were asked to perform two maximum grip strength trials with each hand, in standing position with their arms along their body. Grip strength was recorded to the nearest 1 kg. Upward of wave 3B, grip strength was measured using a JAMAR 5030J1 Hydraulic Hand Dynamometer. Respondents were instructed to perform two maximum grip strength trials with each hand, in seated position with the back straight and elbow bended in a 90° angle. Both dynamometers were adjusted for hand size.

Previous use in LASA
No standardized way of using grip strength data is available from the literature. Within LASA the data have been used in different ways:
- The maximum strength out of two attempts of the dominant† hand; 7
- The sum of the mean strength of the left and right hand; 10
- The average of the highest score of the left and right hand. 11
† The dominant hand can be derived from file LASAB023. If bevmem08=1 then the left hand is dominant, if bevmem08=2 or 3 then the right hand is dominant. Note: in the Migrant cohort only grip strength of the right hand was measured.
Schaap et al. showed that (including data from the Health Aging and Body Composition (Health ABC) Study, low levels of total testosterone and free testosterone were neither associated with 3-year decline in physical performance nor with 3-year decline in muscle strength 12. They also showed that higher levels of IL-6 and CRP (inflammatory markers) increase the risk of grip strength loss, whereas higher levels of ACT decrease the risk of muscle strength loss in older men and women 11, and that low levels of sex hormones were associated with impaired mobility and low muscle strength in men, but not in women 13. Furrer et al. 14 concluded that in men, higher handgrip strength and physical performance are related to higher bone quality and reduced fracture risk, whereas in women, a moderate to high level of physical activity is associated with reduced fracture risk. Research of Gardner et al. 15 showed that there was little evidence of associations between a larger diurnal drop and balance or grip strength. Swart et al. 16 suggested that in men, higher homocysteine levels were associated with lower grip strength.
