Influences of body mass index and waist circumference on physical function in older persons with heart failure

BACKGROUND:

In older persons with heart failure (HF), body composition may influence physical function and treatment effectiveness. There is a lack of research concerning the associations between waist circumference (WC) or body mass index (BMI) and physical function in this population.

OBJECTIVE:

To determine whether BMI and WC are associated with physical function in older men and women with HF.

METHODS:

Seventy-one men and 36 women 65 years of age and older living with HF completed two surveys spaced three months apart. Height, weight, WC, time since diagnosis, edema, comorbidities and physical function were self-reported at baseline and follow-up. Physical function was determined using the physical component score of the Short Form-12 and the physical limitation domain (PLD) of the Kansas City Cardiomyopathy Questionnaire. Multivariate linear regression and analysis of covariance were used to evaluate the relationships between WC and BMI, as well as cross-classifications of WC and BMI with physical function, after adjusting for confounders and interactions.

RESULTS:

The cross-sectional and short-term follow-up analyses did not detect an association between WC or BMI and physical function, with the exception of changes in the PLD, which were significantly different across WC categories. Persons with a moderate WC experienced the greatest improvement in function. The physical component and PLD scores were lower than those reported by Canadians 75 years of age and older and stable HF patients, respectively. Women reported lower physical function scores than men.

CONCLUSION:

Findings from the present study indicate that older persons with HF, especially women, have poor physical functioning regardless of their WC or BMI.

目的 探讨重庆地区人群体重指数（BMI）、腰围（WC）与血压水平及高血压的关系。方法 采用分层整群抽样的方法,抽取重庆地区15岁以上城乡人口5246人进行血压、脉搏、身高、体重、腰围、臀围的测量,并问卷调查。结果 重庆地区人群收缩压、舒张压水平及高血压患病率均随着BMI的增加呈明显的线性上升趋势（线性趋势检验P〈0．01）。腹型肥胖的人群收缩压、舒张压水平及高血压患病率均高于腰围正常的人群,差异均有统计学意义（线性趋势检验P〈0．01）。按BMI分组[〈18．5、18．5～23．9、24．0～27．9、≥28．0（kg／m。）]的高血压患病率分别为9．39％、13．51％、26．23％、32．21％;按WC分组（男〈85cm或女〈80cm,男≥85cm或女≥80cm）的高血压患病率分别为12、39％、28．81％。结论 重庆地区人群血压水平及高血压患病率均与BMI、WC密切相关。BMI、WC是高血压的重要危险因素,对于高血压的发生有着重要的预测作用。     

Prevalence of cardiovascular risk factors in middle-aged Lithuanian women in different body mass index and waist circumference groups

Background and aimsThe aim of this study was to evaluate the prevalence of cardiovascular risk factors in middle-aged Lithuanian women in different body mass index and waist circumference groups.Methods and resultsData selected from the Lithuanian High Cardiovascular Risk (LitHiR) primary prevention program between 2009 and 2016. This community-based cross-sectional study comprised 53,961 women aged 50–64 years old. We compared the prevalence of arterial hypertension, dyslipidaemia, diabetes mellitus, smoking, and metabolic syndrome in different body mass index (BMI) and waist circumference (WC) groups. The most prevalent cardiometabolic risk factor was dyslipidaemia (91.71%, n = 49,488). The prevalence of arterial hypertension, dyslipidaemia, diabetes mellitus, and metabolic syndrome was greater in those with higher-than-normal BMI and WC. Smoking was the most prevalent in women with low BMI and normal WC (24.00% and 13.17% respectively).ConclusionThe analysis showed that all risk factors, except smoking, were significantly more prevalent in women with higher-than-normal BMI and with increased WC or abdominal obesity. The prevalence of dyslipidaemia was surprisingly high in all BMI and WC groups. Obesity measured by WC was more strongly associated with an adverse metabolic profile.     

体重指数和腰围与代谢综合征发生风险的比较研究

目的 比较体重指数、腰围与代谢综合征发生风险的相关性.方法 554例人选者(男316例,女238例),按照体重指数和腰围被分为周围肥胖组192例、腹部肥胖组135例和混合肥胖组237例,7年后进行随访.结果 共随访到520例.周围肥胖组代谢综合征累积发生率26.3%(49/186),腹部肥胖组代谢综合征累积发生率41.7%(50/120),混合肥胖组代谢综合征累积发生率43.0%(92/214).腹部肥胖组和混和肥胖组代谢综合征累积发生率显著高于周围肥胖组(X2分别为7.825和12.082,均P＜0.01),且基线时舒张压、甘油三酯、空腹血糖、空腹胰岛素及稳态模型评估法胰岛素抵抗指数(HOMA-IR)也显著高于前者(均P＜0.05).以有或无代谢综合征分组后基线资料比较,代谢综合征组无论男女,腰围和腰臀比均高于非代谢综合征组(P＜0.01和P＜0.05),体重指数在两组无统计学差异,并且代谢综合征组空腹血糖、空腹胰岛素和HOMA-IR显著高于非代谢综合征组(均P＜0.05).Logistic回归显示,与代谢综合征发生风险相关的因素主要为腰围(P=0.021)、腰臀比(P=0.009)、HOMA-IR(P=0.004).结论 腹部脂肪堆积及胰岛素抵抗是代谢综合征发生的两个重要因素,腰围比体重指数与代谢综合征的发生风险关系更密切.     

体质指数与腰围指标联合应用对心血管病危险的预测作用

目的 分析和评价在体质指数(BMI)分层基础上,增加腰围指标对心血管病危险因素的检出作用以及对心血管病发病危险的预测作用.方法 以1992年建立的中国多省市前瞻性队列35～64岁共30 378人数据为依据,在基线BMI分为正常、超重和肥胖的基础上,分析和评价加入腰围指标对心血管病代谢因素的检出作用以及心血管病发病危险的预测作用.诊断标准分别参照<中国成人超重和肥胖症预防控制指南>中的BMI切点和<中国成人血脂异常防治指南>中的腹部肥胖切点.结果 (1)联合应用BMI和腰围指标诊断肥胖时,呈现交叉重叠情况.以BMI为标准,队列人群肥胖率是10%,其中76.4%的人同时伴有腹部肥胖;以腰围为标准诊断人群腹部肥胖率为17.5%,其中有43.4%的人同时符合BMI的肥胖标准.(2)在BMI分层中加入腰围指标,男女两性有腹部肥胖者其心血管病危险因素患病率均高于无腹部肥胖组.在调整了年龄、性别、吸烟和体力活动等因素后,其特点仍存在,并有统计学的显著性.(3)以BMI和腰围均正常组为对照,多因素分析显示:超重和肥胖组中有腹部肥胖者的缺血性心血管病发病危险分别增加了38%(RR=1.383,95%CI 1.083～1.765)和57%(RR=1.570,95%CI 1.226～2.010).结论 在BMI分层中加入腰围指标可增加心血管病代谢危险因素以及心血管病发病危险的预测作用.

Waist circumference, body mass index and waist to hip ratio for prediction of the metabolic syndrome in Chinese

Background and aimsTo explore the ability of waist circumference (WC), body mass index (BMI) and waist to hip ratio (WHR) to predict two or more non-adipose components of the metabolic syndrome (MetS) among individuals aged 18–85 in North China.Methods and resultsThis study is a cluster sample survey of 101,510 individuals, complete data are 75,788 subjects, 59,874 males and 15,914 females. Their ages were 51.9 ± 12.7 years (males) and 48.7 ± 11.5 years (females). Receiver operating characteristic (ROC) analysis was used to examine discrimination and find optimal cut off values of WC, BMI and WHR to predict two or more non-adipose components of MetS. The area under the ROC curve (AURC) for WC (0.694) and BMI (0.692) in females showed no difference. In males BMI (0.657) had a better discrimination than WC (0.634). WHR was weaker in both sexes. The optimal cut off value of WC in males (86.5 cm) was higher than in females (82.1 cm); and that of BMI was about 24 kg/m² in both genders. The optimal cut off values of WC, BMI, and WHR, increased with age in both sexes.ConclusionsBMI and WC are more useful than WHR for predicting two or more non-adipose components of MetS. Cut off values for WC in males, and those of BMI and WHR in both sexes are lower than that in present MetS criteria; WC in females is slightly higher. Cut off values of WC, BMI and WHR were increased with age in the Chinese.     

Waist-to-height ratio,waist circumference,body mass index,waist divided by height0.5 and the risk of cardiometabolic multimorbidity: A national longitudinal cohort study

Background and aimsCardiometabolic multimorbidity (CM) is an increasing public health burden. This study aimed to evaluate the association of waist-to-height ratio (WHtR), waist circumference (WC), waist divided by height^0.5 (WHT.5R) and body mass index (BMI) with the risk of CM.Methods and resultsWe used data from the China Health and Retirement Longitudinal Study (CHARLS). A total of 10,521 participants aged 45 years and over were recruited, including 8807 individuals with 0 cardiometabolic diseases at baseline (stage I) and 1714 individuals with 1 cardiometabolic disease at baseline (stage II). CM was defined as self-reporting of two or more of the following conditions: stroke, diabetes and heart disease. Logistic regression was conducted to estimate the odds ratios (ORs) and 95% confidence intervals (CIs). The net reclassification index (NRI) and integrated discrimination improvement (IDI) were used to evaluate the incremental predictive value beyond conventional factors. In stage I, an increased risk of CM was observed among participants with WHtR ≥0.5 (OR: 1.76, 95% CI: 1.05–2.97), WC ≥ 90 cm (men) + WC ≥ 80 cm (women) (OR: 2.06, 95% CI: 1.29–3.27), WHT.5R ≥ 6.54 cm^0.5 (OR: 1.81, 95% CI: 1.16–2.83) or BMI ≥24 kg/m² (OR: 1.48, 95% CI: 0.98–2.24). Furthermore, the NRI and IDI of WHtR, WC and WHT.5R were all higher than those of BMI. In stage II, the adjusted ORs (95% CIs) of WHtR, WC, WHT.5R and BMI were 2.04 (1.24–3.35), 1.89 (1.29–2.77), 1.86 (1.24–2.78) and 1.47 (1.06–2.04), respectively. In addition, WC exhibited the highest NRI and IDI.ConclusionWHtR, WC, WHT.5R and BMI are independent predictors of CM in the middle-aged and older Chinese population. WHtR, WC and WHT.5R show better abilities in predicting CM than BMI.
