国际上常用身体质量指数(Body\,Mass\,Index,缩写为BMI)来衡量人体胖瘦及健康程度,其计算公式是BMI=((体重)((单位):kg))(((身高))^2((单位):m^2)). 根据BMI,将人体胖瘦程度划分为四个等级,如表所示: 级别(BMI值μ ) 偏瘦(μ 18.5) 正常(18.5≤ μ 24) 偏胖(24≤ μ 28) 肥胖(μ≥ 28)...
An “obesity paradox” for mortality has been shown in chronic disorders such as diabetes, and attributed to methodological bias, including the use of body mass index (BMI) for obesity definition. This analysis investigated the independent association of BMI versus surrogate measures of central adipos...

We tested the hypothesis that body mass index (BMI) aged 20 years modifies the association of adult weight gain and breast cancer risk. Methods We recruited women (aged 47–73 years) into the PROCAS (Predicting Risk Of Cancer At Screening; Manchester, UK: 2009–2013) Study. In 47,042 wo...
BMI=body-mass index. From 1975 to 2014, trends in men's BMI ranged from virtually flat in Nauru (albeit at a very high level), North Korea, and several countries in sub-Saharan Africa, to an increase of more than 1·5 kg/m2 per decade. Similarly, women's BMI did not change in ...
Objective: To assess the relationship between body mass index (BMI) and adiposity as well as the influence of injury level on this relationship in 24 women with spinal cord injury (SCI) and 23 able-bodied (AB) women with similar age, race, and BMI.Design and Methods: Body composition was...
The relationship between body mass index (BMI) and body fatness could differ according to age, sex, and race-ethnicity. We aimed to evaluate in which contexts BMI could be a good measure for body fatness compared to dual-energy X-ray absorptiometry (DXA) derived measures. The study population...
BACKGROUND: As more people live more of their lives obese, it is unclear what impact this will have on muscle mass, strength, and quality. We aimed to examine the associations of body mass index (BMI) from age 15 years onwards with low muscle mass, strength, and quality in early old ...
Pubertal timing has psychological and physical sequelae. While observational studies have demonstrated an association between age at menarche and adult body mass index (BMI), confounding makes it difficult to infer causality. The Mendelian randomization
