Sex differences in the association of physical activity levels and vitamin D with obesity, sarcopenia, and sarcopenic obesity: a cross-sectional study.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this clinical trial publication.

The researchers aimed to examine the sex differences in the relation between vitamin D status, PA levels, obesity and sarcopenia in community-dwelling middle-aged and older adults, as well as whether vitamin D status is a modifier in the relationship between PA and sarcopenia.

Multinomial logistic regression was performed to examine the relationship between PA, vitamin D and sarcopenia and obesity.

Why It Was Studied

The relationship between vitamin D and sarcopenia was inconsistent between men and women.

Physical activity (PA) may interact with vitamin D on sarcopenia.

Who Took Part

The study group was 3713 participants.

PubMed indexes the participants as middle-aged adults and older adults, both men and women.

A total of 3713 participants aged ≥ 50y were included in their study.

How the Study Was Run

The current study was a cross-sectional study based on the baseline survey of the West China Health and Aging Trend (WCHAT) study.

Sarcopenia was defined according to the Asian Working Group for Sarcopenia (AWGS) 2019 consensus.

Obesity was defined by body mass index (BMI) (≥ 28 kg/m2) and body fat mass percentage (≥ 60th percentile in each sex group). 25-hydroxyvitamin D was measured by chemiluminescent microparticle immunoassay and PA was evaluated by a validated China Leisure Time Physical Activity Questionnaire (CLTPAQ).
