Vitamin D, muscle strength and function in South Asian women aged ≥ 60 years living in the North of England: a cross-sectional observational study.

What Was Tested

This observational study looks at Vitamin D, K2, Magnesium and Zinc.

Most of this evidence for the muscular effect has come from white population groups and the evidence base is sparse for other ethnic groups.

This study investigates the relationship between vitamin D status, muscle strength and function in UK South Asian women aged ≥ 60 years.

Who Took Part

By PubMed's age tags, the people studied were middle-aged adults and older adults, women only.

This cross-sectional study included 120 community-dwelling Indian and Pakistani women, aged ≥ 60 years living in the North of England.

How the Study Was Run

Circulating blood 25(OH)D concentration was assessed by HPLC-MS using finger prick blood samples; functional capacity was assessed using handgrip strength, single and repeated chair stands, timed up and go, and balance test.

Regression analysis was used to analyse the relationships between vitamin D status and muscle strength and function.

What Was Measured
