  • bmi Waist Circumference and risk of incident vertebral fracture in women
    Obesity, 2019
    Co-Authors: Julie M. Paik, Harold N. Rosen, Jeffrey N. Katz, Bernard Rosner, Eric B. Rimm, Catherine M. Gordon, Gary C. Curhan
    Abstract:

    OBJECTIVE The study aimed to investigate the association between BMI, Waist Circumference, and vertebral fracture (VF) risk in women. METHODS This prospective study was conducted in 54,934 Nurses' Health Study participants. BMI was assessed biennially, and Waist Circumference was assessed in the year 2000. Self-reports of VF were confirmed by record review. BMI reflects lean body mass, and Waist Circumference reflects abdominal adiposity when included in the same regression model. RESULTS This study included 536 VF cases (2002 to 2014). Compared with women with BMI of 21.0 to 24.9 kg/m2 , the multivariable-adjusted relative risk (RR) of VF for women with BMI ≥ 32.0 was 0.84 (95% CI: 0.61-1.14; Ptrend  = 0.08). After further adjustment for Waist Circumference, the multivariable-adjusted RR of VF for women with BMI ≥ 32.0 was 0.70 (95% CI: 0.49-0.98; Ptrend  = 0.003). Compared with women with Waist Circumference < 71.0 cm, the multivariable-adjusted RR of VF for women with Waist Circumference ≥ 108.0 cm was 1.76 (95% CI: 1.06-2.92; Ptrend  = 0.01), and after further adjustment for BMI, the multivariable-adjusted RR of VF was 2.49 (95% CI: 1.44-4.33; Ptrend  < 0.001). CONCLUSIONS Greater lean body mass was independently associated with lower VF risk. Larger Waist Circumference was independently associated with higher VF risk. These findings suggest that fat distribution is an important predictor of VF and that avoiding central adiposity, as well as maintaining muscle mass, may potentially confer reduced risk of VF in older women.

  • body mass index Waist Circumference physical activity and risk of hearing loss in women
    The American Journal of Medicine, 2013
    Co-Authors: Sharon G Curhan, Gary C. Curhan, Roland D Eavey, Molin Wang, Meir J Stampfer
    Abstract:

    Abstract Background Acquired hearing loss is highly prevalent, but prospective data on potentially modifiable risk factors are limited. In cross-sectional studies, higher body mass index (BMI), larger Waist Circumference, and lower physical activity have been associated with poorer hearing, but these have not been examined prospectively. Methods We examined the independent associations between BMI, Waist Circumference, and physical activity, and self-reported hearing loss in 68,421 women in the Nurses' Health Study II from 1989 to 2009. Baseline and updated information on BMI, Waist Circumference, and physical activity was obtained from biennial questionnaires. Results After more than 1.1 million person-years of follow-up, 11,286 cases of hearing loss were reported to have occurred. Higher BMI and larger Waist Circumference were associated with increased risk of hearing loss. Compared with women with BMI 2 , the multivariate-adjusted relative risk (RR) for women with BMI ≥40 was 1.25 (95% confidence interval [CI], 1.14-1.37). Compared with women with Waist Circumference 88 cm was 1.27 (95% CI, 1.17-1.38). Higher physical activity was related inversely to risk; compared with women in the lowest quintile of physical activity, the multivariate-adjusted RR for women in the highest quintile was 0.83 (95% CI, 0.78-0.88). Walking 2 hours per week or more was associated inversely with risk. Simultaneous adjustment for BMI, Waist Circumference, and physical activity slightly attenuated the associations but they remained statistically significant. Conclusions Higher BMI and larger Waist Circumference are associated with increased risk, and higher physical activity is associated with reduced risk of hearing loss in women. These findings provide evidence that maintaining healthy weight and staying physically active, potentially modifiable lifestyle factors, may help reduce the risk of hearing loss.

  • BMI, Waist Circumference, and incident urinary incontinence in older women.
    Obesity (Silver Spring Md.), 2008
    Co-Authors: Mary K. Townsend, Gary C. Curhan, Neil M. Resnick, Francine Grodstein
    Abstract:

    Overall body fat and central adiposity may reflect different mechanisms leading to urinary incontinence (UI). We examined the associations of BMI and Waist Circumference with incident UI, including the independent associations of BMI and Waist Circumference with UI type, among women aged 54-79 years in the Nurses' Health Study. Study participants reported their height in 1976 and their weight and Waist Circumference in 2000. From 2000 to 2002, we identified 6,790 women with incident UI at least monthly among 35,754 women reporting no UI in 2000. Type of incontinence was determined on questionnaires sent to cases with at least weekly incontinence. Relative risks (RRs) and 95% confidence intervals (CIs) were estimated using multiple logistic regression. There were highly significant trends of increasing risk of UI with increasing BMI and Waist Circumference (P for trend or =35 kg/m(2) to women with BMI 21-22.9 kg/m(2) and 1.72 (95% CI 1.53-1.95) comparing women in extreme quintiles of Waist Circumference. When BMI and Waist Circumference were included in models simultaneously, BMI was associated with urge and mixed UI (P for trend 0.003 and 0.03, respectively), but not stress UI (P for trend 0.77). Waist Circumference was associated only with stress UI (P for trend

  • Waist Circumference percentiles for Canadian youth 11–18 y of age
    European journal of clinical nutrition, 2004
    Co-Authors: Peter T. Katzmarzyk
    Abstract:

    Objective: To develop age- and sex-specific Waist Circumference reference data for Canadian youth. Design: Cross-sectional population survey. Setting: 1981 Canada Fitness Survey. Subjects: Nationally representative sample of 3064 youth (1540 boys and 1524 girls) 11–18 y of age. Interventions: Waist Circumference was measured with a flexible anthropometric tape. Main outcome measures: Smoothed and weighted 5th, 10th, 25th, 50th, 75th, 90th, and 95th Waist Circumference percentiles derived from LMS regression. Results: Waist Circumference increases with age in both boys and girls, and boys have higher values of Waist Circumference than girls at every age and percentile level. Conclusions: These reference data can be used to identify youth with an elevated risk of developing obesity-related disorders and can serve as a baseline for future studies of temporal trends in Waist Circumference. Sponsorship: This research was funded by the Heart and Stroke Foundation of Ontario (Grant #T4946).

  • Are the recent secular increases in the Waist Circumference of adults independent of changes in BMI
    The American journal of clinical nutrition, 2015
    Co-Authors: David S. Freedman, Earl S. Ford
    Abstract:

    Background Several studies showed that the Waist Circumference of US adults has increased over the past 25 y. However, because of the high correlation between Waist Circumference and body mass index (BMI; in kg/m2) (r ~ 0.9), it is uncertain if these trends in Waist Circumference exceed those expected on the basis of BMI changes over this time period.

  • trends in mean Waist Circumference and abdominal obesity among us adults 1999 2012
    JAMA, 2014
    Co-Authors: Earl S. Ford, Leah M Maynard
    Abstract:

    Waist Circumference is a simple and valuable anthropometric measure of total and intra-abdominal body fat.1 The clinical guidelines from the National Heart, Lung, and Blood Institute on the identification, evaluation, and treatment of overweight and obesity in adults recommend that clinicians assess Waist Circumference of their patients.2 Although the prevalence of abdominal obesity has increased in the United States through 2008,3 its trend in recent years is unknown. Therefore, our objective was to provide recent information about the trends in mean Waist Circumference and prevalence of abdominal obesity among adults in the United States from 1999 to 2012.

  • recent trends in Waist Circumference and Waist height ratio among us children and adolescents
    Pediatrics, 2006
    Co-Authors: Earl S. Ford, Ali H. Mokdad, Stephen Cook
    Abstract:

    OBJECTIVES. Abdominal obesity may be a better predictor than overall obesity for the risk of cardiovascular disease and type 2 diabetes. Waist Circumference and Waist-height ratio are 2 simple, yet effective, surrogate measures of abdominal obesity. We sought to examine the recent trends in mean Waist Circumference and Waist-height ratio and prevalence of abdominal obesity among children and adolescents aged 2 to 19 years in the United States. METHODS. Representative samples of the civilian, noninstitutionalized US population from the National Health and Nutrition Examination Survey conducted during 4 time periods, 1988–1994 (ie, National Health and Nutrition Examination Survey III), 1999–2000, 2001–2002, and 2003–2004, were examined to estimate the mean Waist Circumference and Waist-height ratio of boys and girls in 4 different age groups. Data from the 3 most recent National Health and Nutrition Examination Surveys were combined to establish a National Health and Nutrition Examination Survey 1999–2004 category. RESULTS. Categorized by age group, the unadjusted mean Waist Circumference for boys increased between National Health and Nutrition Examination Survey III and National Health and Nutrition Examination Survey 1999–2004 from 50.7 cm (aged 2–5 years), 61.9 cm (aged 6–11 years), 76.8 cm (aged 12–17 years), and 81.3 cm (aged 18–19 years) to 51.9, 64.5, 79.8, and 86.6 cm, respectively. During the same time periods and within the same age groups, the unadjusted mean Waist Circumference for girls increased from 51.0, 61.7, 75.0, and 77.7 cm to 51.8, 64.7, 78.9, and 83.9 cm, respectively. The relative change in Waist-height ratio was similar to Waist Circumference at each age group for both boys and girls. Using the 90th percentile values of Waist Circumference for gender and age, the prevalence of abdominal obesity increased by 65.4% (from 10.5% to 17.4%) and 69.4% (from 10.5% to 17.8%) for boys and girls, respectively. CONCLUSIONS. Mean Waist Circumference and Waist-height ratio and the prevalence of abdominal obesity among US children and adolescents greatly increased between 1988–1994 and 1999–2004.

  • Trends in Waist Circumference among U.S. Adults
    Obesity research, 2003
    Co-Authors: Earl S. Ford, Ali H. Mokdad, Wayne H. Giles
    Abstract:

    Objective: Waist Circumference has been proposed as a measure of obesity or as an adjunct to other anthropometric measures to determine obesity. Our objective was to examine temporal trends in Waist Circumference among adults in the U.S. Research Methods and Procedures: We used data from 15, 454 participants ≥20 years old in National Health and Nutrition Examination Survey (NHANES) III (1988 to 1994) and 4024 participants ≥20 years old from National Health and Nutrition Examination Survey 1999 to 2000. Results: The unadjusted Waist Circumference increased from 95.3 (age-adjusted, 96.0 cm) to 98.6 (age-adjusted, 98.9 cm) cm among men and from 88.7 (age-adjusted 88.9 cm) to 92.2 (age-adjusted 92.1 cm) cm among women. The percentiles from the two surveys suggest that much of the Waist Circumference distribution has shifted. Statistically significant increases occurred among all age groups and racial or ethnic groups except men 30 to 59 years old, women 40 to 59 and ≥70 years old, and women who were Mexican American or of “other” race or ethnicity. Discussion: These results demonstrate the rapid increase in obesity, especially abdominal obesity, among U.S. adults. Unless measures are taken to slow the increase in or reverse the course of the obesity epidemic, the burden of obesity-associated morbidity and mortality in the U.S. can be expected to increase substantially in future years.

  • Waist Circumference percentiles among Turkish children under the age of 6 years
    European journal of pediatrics, 2012
    Co-Authors: Nihal Hatipoğlu, M. Mümtaz Mazıcıoğlu, Serpil Poyrazoğlu, Arda Borlu, Duygu Horoz, Selim Kurtoglu
    Abstract:

    Waist Circumference, a proxy measure of abdominal obesity, is associated with cardio-metabolic risk factors in childhood and adolescence. Although there are numerous studies about Waist Circumference percentiles in children, only a few studies cover preschool children. The aim of this study was to develop age- and gender-specific Waist Circumference smoothed reference curves in Turkish preschool children to determine abdominal obesity prevalence and to compare them with reference curves obtained from different countries. The design of the study was cross-sectional. A total of 2,947 children (1,471 boys and 1,476 girls) aged 0–6 years were included in the study. The subjects were divided according to their gender. Waist Circumference was measured by using a standardized procedure. The age- and gender-specific Waist Circumference reference curves were constructed and smoothed with LMS method. The reference values of Waist Circumference, including 3rd, 10th 25th, 50th, 75th, 90th, and 97th percentiles, and standard deviations were given for preschool children. Waist Circumference values increased with age, and there were differences between genders. The prevalence of abdominal obesity was calculated as 10.1 % for boys and 10.7 % for girls. Having compared our data with two other countries’ data, we found that our Waist Circumference data were significantly lower. This is the first cross-sectional study for age- and gender-specific references of 0- to 6-year-old Turkish children. The gender- and age-specific Waist Circumference percentiles can be used to determine the risk of central obesity.

  • Waist Circumference percentiles for 7- to 17-year-old Turkish children and adolescents.
    European journal of pediatrics, 2007
    Co-Authors: Nihal Hatipoğlu, M. Mümtaz Mazıcıoğlu, Selim Kurtoglu, Ahmet Öztürk, Selda Seyhan, Fikret Lokoglu
    Abstract:

    Abdominal obesity is associated with risk of cardiovascular disease and type 2 diabetes mellitus. Waist Circumference as a measure of obesity may be clinically useful as a predictor of metabolic syndrome in children. To develop age- and sex-specific reference values for Waist Circumference we evaluated the data obtained from Turkish children and adolescents. Waist Circumference measurements from 4,770 healthy schoolchildren were obtained. Smoothed percentile curves were produced by the LMS method. The median curves of Turkish children were compared with four other countries: Australia, the UK, USA (Bogalusa) and Japan. Smoothed percentile curves and values for the 3rd, 5th, 10th, 25th, 50th, 75th, 85th, 90th, 95th and 97th percentiles were calculated for boys and girls. We found that Waist Circumference increased with age both in boys and girls. The 50th percentile Waist Circumference curve of Turkish children was over the British and Japanese but lower than the Bogalusa children and adolescents. This study presents data and smoothed percentile curves for Waist Circumference of healthy Turkish children aged 7–17 years. The differences in Waist Circumference of different countries can be explained by lifestyles and cultural characteristics. These data can be added to the existing international reference values for Waist Circumference of children and adolescents.
