The epidemic of stroke mortality attributed to high body mass index in mainland China: Current trends and future prediction

Abstract

BackgroundHigh body mass index (BMI) is an important risk factor for stroke. The aim of this study was to assess the long-term trend of high BMI-attributed stroke mortality and make projections through 2030.MethodsData were extracted from the Global Burden of Disease Study 2019 and World Population Prospects 2019. An age-period-cohort framework was used in the analysis.ResultsFrom 1990 to 2019, the age-standardized mortality rate (ASMR) of high BMI-attributed stroke among females decreased by 15.2%, while among males, it increased by 31.1%. All of the age groups studied showed an increasing pattern over the last 30 years in males, and in female, the age groups encompassing participants who were 25–69 years old showed a decreasing pattern. In the same birth cohort, high BMI-attributable stroke mortality rates increased exponentially with age in both sexes. For females, the period rate ratios (RR) showed a downward trend after 2000–2004, and the cohort RR also showed a downward trend after the birth cohort 1930–1934. For males, the period RR showed an upward trend, but this increase was halted in the most recent period, and the cohort RRs showed a monotonic increasing pattern. It was projected that the ASMR of high BMI-attributed stroke would decrease among females and increase among males in the near future and that the proportion of elderly individuals with death due to high BMI-attributed stroke was projected to increase.ConclusionsOver the last three decades, the high BMI-attributed stroke mortality rate decreased among females and increased among males, and these trends are projected to continue in the future. In addition, the proportion of elderly individuals with high BMI-attributed stroke mortality was projected to increase gradually in both men and women. More health-promoting efforts are needed, especially for elderly individuals and males.

Prevalence and influencing factors of malnutrition in stroke patients with bulbar paralysis: a cross-sectional study in China

“…Data on personal information and illness were based on medical records. Specifically, the patients BMI was assessed with the combination of height and body weight, where BMI < 18.5 kg/m 2 was classified as underweight, BMI ranging from 18.5 to 23.9 kg/m 2 was considered normal weight, BMI between 24.0 and 27.9 kg/m 2 was categorized as overweight, and BMI ≥ 28.0 kg/m 2 was classified as obesity ( 18 ). A patient who had smoked at least one cigarette per week for at least 6 months prior to the day of the investigation was regarded as smoking-Yes based on self-report ( 3 ).…”

Long-term trends in Alzheimer’s disease and other dementias deaths with high body mass index in China from 1990 to 2019, and projections up to 2042

“…The standardized population used in this study was derived from the world standard population compiled by GBD 2019, using a direct standardization method to age-standardize mortality from high BMI leading to AD and other dementias. High BMI in adults (age 18 + years) was defined as BMI ≥ 25 kg / m 2 [ 14 ].…”

How stroke-related dysphagia relates to quality of life: the mediating role of nutritional status and psychological disorders, and the moderating effect of enteral nutrition mode

“…Neurological impairments resulting from stroke, including decreased muscle strength and coordination, negative mental conditions, and limited verbal abilities, significantly impact patients’ quality of life (QOL) ( 3 , 4 ). With global aging, stroke has emerged as a major public health threat ( 5 ). Dysphagia, one of the most frequent and potential complications of stroke, occurs in 37–78% of cases and is associated with pneumonia and malnutrition ( 6 ).…”
