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.

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.     

Association of waist circumference,body mass index and conicity index with cardiovascular risk factors in postmenopausal women

Abstract

In menopause, changes in body fat distribution lead to increasing risk of cardiovascular disease and metabolic disorders. The aim of this study was to assess the association of adiposity using the conicity index (CI), body mass index (BMI) and waist circumference (WC) with cardiovascular risk factors (hypertension, diabetes and dyslipidaemia). The sample of this cross-sectional study was collected from June to October 2010 and 165 consecutive menopausal women who had attended the Health and Treatment Centre and Endocrine Research Centre of Firoozgar Hospital in Tehran, Iran were assessed. Age, weight, height, WC, waist–hip ratio (WHR), CI and fat mass were measured. Systolic and diastolic blood pressure (SBP and DBP), fasting blood glucose, insulin, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and total cholesterol (TC) levels were also determined. All statistical analyses were performed by SPSS version 17 (SPSS Inc, Chicago, IL, USA).Results showed that BMI was positively and significantly associated with SBP (r = 0.21; p = 0.009). WC was positively and significantly correlated with SBP (r = 0.26; p = 0.02) and DBP (r = 0.16; p = 0.05). WHR was also significantly and positively associated with SBP (r = 0.29; p = 0.001). Age and WC were associated with CI quartiles at the 0.05 significance level. The correlation of CI quartiles with SBP and weight were at the 0.01 significance level.We showed a significant association of WC with SBP and DBP, and that BMI could be an important determining factor of SBP. For assessing the association between CI and cardiovascular risk factors, future studies with larger sample sizes are recommended.     

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.     

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.
