Key result
Body mass index (≥28.0 vs 24.0-28.0 kg/m²) was negatively associated with depression scores in stroke patients aged ≥65 years, but showed a U-shaped curve in those <65 years.
Why the study?
Poststroke depression is a common complication of stroke, prompting investigation into its influencing factors and the specific association between BMI and poststroke depression.

What are the influencing factors of poststroke depression and how is BMI associated with it in stroke patients?
BMI and sleep duration are significant influencing factors for poststroke depression, with BMI having age-dependent effects.
May support age-specific BMI considerations in post-stroke depression screening but should not change practice; leaves open causal links for prospective studies.
Poststroke depression (PSD) is a common complication of stroke. We sought to investigate the influencing factors of PSD and explored the association between body mass index (BMI) and PSD. A total of 397 stroke patients in a hospital in Qiqihar City, China, were included in this study in 2016. The order of independent variable importance was the score of the National Institute of Health Stroke Scale, frequency of stroke, age, BMI, and sleep duration. Sleep duration of 7 hours or more (compared with <7 hours) was negatively associated with the Self-Rating Depression Scale (SDS) score in all quantiles. BMI of 28.0 kg/m or more (compared with 24.0-28.0 kg/m) was negatively associated with SDS score, and the coefficients manifested a continuous increasing trend from P30 to P84.1 in patients aged 65 years or more. In addition, the relationship between BMI and SDS score demonstrated a "U"-shaped curve in patients aged less than 65 years. The National Institute of Health Stroke Scale score, the frequency of stroke, sleep duration, and BMI were the influencing factors of PSD. BMI played different roles in the two age groups.

Xue et al. (2019) conducted an observational in Poststroke depression (n=397). Body mass index (BMI) and sleep duration vs. Lower BMI or shorter sleep duration was evaluated on Self-Rating Depression Scale (SDS) score. Body mass index (≥28.0 vs 24.0-28.0 kg/m²) was negatively associated with depression scores in stroke patients aged ≥65 years, but showed a U-shaped curve in those <65 years.
