Individual changes in anthropometric measures after age 60 years: a 15-year longitudinal population-based study.

ABSTRACT:

Background

weight loss is commonly observed with ageing. We explored the trajectory of body mass index (BMI) and two proxies of muscle mass-calf circumference (CC) and mid-arm circumference (MAC)-and identified their determinants.

Methods

within the SNAC-K cohort, 2,155 dementia-free participants aged ≥60 years were followed over 15 years. BMI, CC and MAC were measured at baseline and follow-ups. Baseline sociodemographic and lifestyle factors were collected through interviews. Diabetes and vascular disorders were diagnosed by physicians through clinical examination and medical records. Data were analysed using linear mixed-effect models stratified by age (younger-old [<78 years] vs. older-old [≥78 years]).

Results

over the 15-year follow-up, BMI remained stable among
