Association of Anthropometric Measures With the Risk of Prostate Cancer in the Multiethnic Cohort.

In studies of anthropometric measures and prostate cancer risk, conducted primarily in White men, positive associations with advanced disease have been reported. We assessed body size in relation to incident prostate cancer risk in 79,950 men from the Multiethnic Cohort, with 8,819 cases identified over 22 years (1993-2015). Height was associated with increased risk of advanced prostate cancer (≥68 inches (≥ 173 cm) vs. < 66 inches (168 cm); hazard ratio (HR) = 1.24, 95% confidence interval (CI): 1.04, 1.48) and high-grade disease (HR = 1.15, 95% CI: 1.02, 1.31). Compared with men of normal weight, men overweight at baseline were at higher risk of high-grade cancer (HR = 1.15, 95% CI: 1.04, 1.26). Greater weight was positively associated with localized and low-grade disease in Blacks and Native Hawaiians (by race, P for heterogeneity = 0.0002 and 0.008, respectively). Weight change since age 21 years was positively associated with high-grade disease (for ≥ 40 pounds (18 kg) vs. 10 pounds (4.5 kg), HR = 1.20, 95% CI: 1.05, 1.37; P for trend = 0.005). Comparing highest versus lowest quartile, waist-to-hip ratio was associated with a 1.78-fold increase (95% CI: 1.28, 2.46) in the risk of advanced prostate cancer. Positive associations with the majority of anthropometric measures were observed in all 5 racial/ethnic groups, suggesting a general impact of anthropometric measures on risk across populations.

The joint effects of major lifestyle factors on colorectal cancer risk among Chinese men: A prospective cohort study.

Previous studies have suggested individual healthy lifestyle factors are related to lower risk of colorectal cancer. Their joint effects, however, have rarely been investigated. We aimed to assess the combined lifestyle impact on colorectal cancer risk and to estimate the population attributable risks of these lifestyle factors. Using data from the Shanghai Men's Health Study (2002-2013), we constructed healthy lifestyle index composing the following lifestyle factors: smoking, alcohol consumption, diet, waist-hip ratio and exercise participation. Cox proportional hazards models were used to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs). Over a median of 9.28 years' follow-up, 671 colorectal cancer cases occurred (400 colon cancer and 274 rectal cancer) among 59,503 men. Each increment of healthy lifestyle index was associated with a 17% lower risk of colorectal cancer (HR = 0.83, 95% CI: 0.78, 0.89), 10% of colon cancer (HR = 0.90, 95% CI: 0.83, 0.99) and 27% of rectal cancer (HR = 0.73, 95% CI: 0.66, 0.82). If all men in the cohort followed a lifestyle as defined by these five factors, 21% colorectal cancer cases would have been prevented (PAR = 21%, 95% CI: 4%, 36%). In conclusion, combined lifestyle factors are significantly related to lower risk of colorectal cancer and the effects are more pronounced on rectal cancer than on colon cancer.

Abdominal obesity and colorectal cancer risk: systematic review and meta-analysis of prospective studies.

The association between abdominal obesity (as measured by waist circumference (WC) and waist-to-hip ratio (WHR)) and colorectal cancer (CRC) has not been fully quantified, and the magnitude of CRC risk associated with abdominal obesity is still unclear. A meta-analysis of prospective studies was performed to elucidate the CRC risk associated with abdominal obesity. Pubmed and Embase were searched for studies assessing the association between abdominal obesity and CRC risk. Relative risks (RRs) with 95% confidence intervals (95% CIs) were pooled using random-effects model of meta-analysis. Nineteen prospective cohort studies from eighteen publications were included in this meta-analysis. A total of 12,837 CRC cases were identified among 1,343,560 participants. Greater WC and WHR were significantly associated with increased risk of total colorectal cancer (WC: RR 1.42, 95% CI 1.30, 1.55; WHR: RR 1.39, 95% CI 1.25, 1.53), colon cancer (WC: RR 1.53, 95% CI 1.36, 1.72; WHR: 1.39, 95% CI 1.18, 1.63), and rectal cancer (WC: RR 1.20, 95% CI 1.03, 1.39; WHR: RR 1.22, 95% CI 1.05, 1.42). Subgroup analyses further identified the robustness of the association above. No obvious risk of publication bias was observed. In summary, abdominal obesity may play an important role in the development of CRC.

Prediagnosis body mass index and waist-hip circumference ratio in association with colorectal cancer survival.

The association of obesity on survival among patients with colorectal cancer (CRC) has not been well characterized. We investigated the association of prediagnostic body mass index (BMI)/waist-hip ratio (WHR) and total/cause-specific mortality in CRC patients. Our study included 1,452 patients who participated in two large cohort studies and were diagnosed with CRC during follow-up period. Participants were measured for anthropometrics and interviewed to collect relevant information at baseline, prior to any cancer diagnosis. Data on site-specific cancer incidence and cause-specific mortality were obtained via in-person surveys and annual record linkage with cancer and vital statistics registries. Cox proportional hazard models were used to evaluate the associations of BMI and WHR with survival. A total of 547 participants died during the follow-up period, including 499 who died of CRC. Relative to normal BMI (18.5 to <25.0 kg/m2 ), obesity (BMI ≥ 30 kg/m2 ) was associated with increased mortality resulting from all causes [hazard ratio (HR) = 1.5, 95% confidence interval (CI): 1.1-2.1] and CRC (HR = 1.5, 95% CI: 1.1-2.1). Elevated risk of death was also found among underweight patients (BMI < 18.5 kg/m2 ), although not all risk estimates were statistically significant. Overweight BMI (25.0 to <30.0 kg/m2 ) was not associated with risk of death among CRC patients, nor was WHR. In conclusion, prediagnostic BMI was associated with survival among CRC patients following a U-shape pattern; obesity was associated with high mortality after CRC diagnosis. These findings provide support for maintaining healthy weight to improve the survival of CRC patients.

Comparing measures of overall and central obesity in relation to cardiometabolic risk factors among US Hispanic/Latino adults.

OBJECTIVE: US Hispanics/Latinos have high prevalence of obesity and related comorbidities. We compared overall and central obesity measures in associations with cardiometabolic outcomes among US Hispanics/Latinos. METHODS: Multivariable regression assessed cross-sectional relationships of six obesity measures with cardiometabolic outcomes among 16,415 Hispanics/Latinos aged 18-74 years. RESULTS: BMI was moderately correlated with waist-to-hip ratio (WHR; women, r = 0.37; men, r = 0.58) and highly correlated with other obesity measures (r ≥ 0.87) (P < 0.0001). All measures of obesity were correlated with unfavorable levels of glycemic traits, blood pressure, and lipids, with similar r-estimates for each obesity measure (P < 0.05). Multivariable-adjusted prevalence ratios (PRs) for diabetes (women, 6.7 [3.9, 11.5]; men, 3.9 [2.2, 6.9]), hypertension (women, 2.4 [1.9, 3.1]; men, 2.5 [1.9, 3.4]), and dyslipidemia (women, 2.1 [1.8, 2.4]; men, 2.2 [1.9, 2.6]) were highest for individuals characterized as overweight/obese (BMI ≥ 25 kg/m(2)) and with abnormal WHR (women ≥0.85; men, ≥0.90), compared with those with normal BMI and WHR (P < 0.0001). Among normal-weight individuals, abnormal WHR was associated with increased cardiometabolic condition prevalence (P < 0.05), particularly diabetes (women, PR = 4.0 [2.2, 7.1]; men, PR = 3.0 [1.6, 5.7]). CONCLUSIONS: Obesity measures were associated with cardiometabolic risk factors to a similar degree in US Hispanics/Latinos. WHR is useful to identify individuals with normal BMI at increased cardiometabolic risk.

Maternal waist to hip ratio is a risk factor for macrosomia.

OBJECTIVE: Fetal growth during pregnancy may be affected by the metabolic activity and distribution of fat stores in women. This study investigates the association between waist to hip ratio (WHR) as a measure of the distribution of adiposity in primiparous mothers living in Avon, England, and macrosomia in their offspring. DESIGN: Prospective historical cohort study. SETTING: The Avon Longitudinal Study of Parents and Children (ALSPAC) prospective cohort study in Avon, UK. POPULATION: A cohort of 3083 primiparous women with a term singleton delivery with expected dates of delivery from 1 April 1991 to 31 December 1992. METHODS: The distribution of WHR was categorised into quartiles. We compared the second, third and fourth quartiles against the first (reference) quartile with respect to whether the mother delivered a macrosomic newborn. We controlled for maternal age, gestational age, body mass index (BMI), marital status and racial group using multivariate logistic regression. MAIN OUTCOME MEASURES: Macrosomia defined in three ways: birthweight ≥ 4000 g; birthweight ≥ 4500 g; large for gestational age (LGA: ≥ 95th percentile of birth weight adjusted for sex and gestational age). RESULTS: Waist to hip ratios in the third and fourth quartiles were associated with a higher odds of delivering a macrosomic infant, defined as a birthweight ≥ 4000 g (third quartile, OR 1.59, 95% CI 1.12-2.26; fourth quartile, OR 1.69, 95% CI 1.18-2.42) or as LGA (≥95th percentile of the cohort; third quartile, OR 1.77, 95% CI 1.10-2.85; fourth quartile, OR 1.78, 95% CI 1.09-2.91). When defined as a birthweight ≥ 4500 g, the fourth quartile was associated with increased odds of macrosomia (OR 2.74, 95% CI 1.05-7.16). Odds ratios after adjustment for confounding factors followed a similar pattern. CONCLUSION: Independent of confounding factors, women with increased WHRs were significantly more likely to give birth to macrosomic newborns.

The association of anthropometric measures and osteoarthritis knee in non-obese subjects: a cross sectional study.

OBJECTIVE: Body mass index (BMI) and knee osteoarthritis have a strong association, but other anthropometric measures lack such associations. To date, no study has evaluated non-obese knee osteoarthritis to negate the systemic and metabolic effects of obesity. This study examines the validity of the contention that BMI and other anthropometric measures have a significant relationship with knee osteoarthritis. METHODS: In total, 180 subjects with a diagnosis of knee osteoarthritis were recruited and classified according to Kellgren-Lawrence (KL) grades. Body mass index, mid-upper arm circumference, waist-hip ratio and triceps-skinfold thickness were recorded by standard procedures. Osteoarthritis outcome scores (WOMAC) were evaluated. RESULTS: (1) In both genders, the BMI was significantly higher for KL grade 4 than for grade 2; triceps-skinfold thickness was positively correlated with the joint space width of the tibial medial compartment. (2) In males, triceps-skinfold thickness significantly increased as the KL grades moved from 2 to 4; the significantly higher BMI found in varus aligned knees was positively correlated with WOMAC scores. (3) In females, the waist-hip ratio was significantly higher for KL grade 4 than for grade 2; a significant correlation was found between BMI and WOMAC scores. The waist-hip ratio was significantly associated with varus aligned knees and it positively correlated with WOMAC scores and with the joint space width of the tibial medial compartment. The mid-upper arm circumference demonstrated no correlation with knee osteoarthritis. CONCLUS'ON: This study validates the contention that BMI and other anthropometric measures have a significant association with knee osteoarthritis. Contrary to common belief, the triceps-skinfold thickness (peripheral fat) in males and the waist-hip ratio (central fat) in females were more strongly associated with knee osteoarthritis than BMI.

Joint effects of physical activity, body mass index, waist circumference, and waist-to-hip ratio on the risk of heart failure.

BACKGROUND: Obesity increases heart failure (HF) risk; however, the independent effect of physical activity and the joint effect of physical activity and adiposity on HF risk are not established. We evaluated the single and joint associations of physical activity and different indicators of adiposity (body mass index, waist circumference, and waist-to-hip ratio) with HF risk. METHODS AND RESULTS: Study cohorts included 59 178 Finnish participants who were 25 to 74 years of age and free of HF at baseline. During a mean follow-up of 18.4 years, 1921 men and 1693 women developed HF. The multivariable-adjusted hazard ratios of HF associated with low, moderate, and high physical activity were 1.00, 0.79, and 0.69 (P(trend)<0.001) for men and 1.00, 0.86, and 0.68 (P(trend)<0.001) for women, respectively. The multivariable-adjusted hazard ratios of HF at different levels of body mass index (<25, 25 to 29.9, and >or=30 kg/m(2)) were 1.00, 1.25, and 1.99 (P(trend)<0.001) for men and 1.00, 1.33, and 2.06 (P(trend)<0.001) for women, respectively. Abdominal adiposity, measured by waist circumference or waist-to-hip ratio, was associated with a greater risk of HF among both men and women (all P(trend)<0.01). In joint analyses, the protective effect of physical activity was consistent in subjects at all levels of body mass index. CONCLUSIONS: General overweight and general and abdominal obesity are independently associated with an increased risk of HF, whereas moderate or high levels of physical activity are associated with a reduced risk of HF. The protective effect of physical activity on HF risk is observed at all levels of body mass index.

Fundamento: A hipertensão arterial sistêmica (HAS), considerada um problema de saúde pública devido a sua elevada prevalência e dificuldade de controle, é descrita também como um dos mais importantes fatores de risco para doenças cardiovasculares. Objetivo: Estimar a prevalência da HAS, assim como as características de seu controle e tratamento, na população de 18 a 90 anos da região urbana de Nobres - MT. Métodos: Estudo transversal, de base populacional, com amostragem aleatória e com reposição. O critério para classificação da HAS foi pressão arterial (PA) > 140/90 mmHg ou uso atual de anti-hipertensivos. As entrevistas foram realizadas utilizando-se questionários padronizados e testados previamente. As variáveis foram descritas por médias ± desvios-padrão e frequências. As médias foram comparadas utilizando-se o teste t-Student e as associações por meio do teste do qui-quadrado de Pearson, com nível de significância de 5 por cento. Resultados: Nos 1.003 indivíduos maiores de 18 anos analisados, foi observada prevalência de HAS de 30,1 por cento. Entre os hipertensos (N = 302), 73,5 por cento sabiam dessa condição, 61,9 por cento faziam tratamento e 24,2 por cento tinham a PA controlada. Observou-se a associação positiva entre HAS e idade; analfabetismo; escolaridade inferior a oito anos; IMC > 25kg/m²; circunferência da cintura aumentada e muito aumentada; razão cintura-quadril (RCQ) em faixa de risco; sedentarismo e etilismo. Conclusão: A HAS revelou-se um importante problema de saúde pública também em um município de pequeno porte do interior do país. Os níveis de controle e tratamento da hipertensão nessa população foram considerados insatisfatórios, apesar de melhores em comparação aos observados em outros estudos.

Background: Systemic Arterial Hypertension (SAH), considered a public health problem due to its high prevalence and difficult control, is also described as one of the most important risk factors for cardiovascular diseases. Objective: This study aimed to determine the prevalence of SAH, as well as characteristics related to its control and treatment, among individuals aging between 18 and 90 years from the urban region of Nobres, MT. Methods: Cross-sectional, population-based study, with random sampling and with replacement. For classification of SAH, criteria included blood pressure (BP) > 140/90 mmHg or current use of antihypertensive drugs. Individuals were interviewed with standardized questionnaires previously tested. Variables were described as means ± standard deviations and frequencies. Means were compared with the Student´s t test and associations were determined with the Pearson chi-square test, with a significance level of 5 percent. Results: SAH has a prevalence of 30.1 percent in the sample, composed of 1,003 individuals older than 18 years. Among hypertensive individuals (N = 302), 73.5 percent knew about their condition, 61.9 percent were under treatment and for 24.2 percent the BP was under control. A positive association was observed between SAH and age; illiteracy; less than 8 years education; BMI > 25 kg/m²; high and very high waist circumference; waist-hip ratio (WHR) at risk level; sedentariness; and alcoholism. Conclusions: This study showed that SAH represents an important public health problem even in a small district in the interior region of Brazil. Levels of control and treatment of hypertension in the population were higher than those observed in similar studies, but were considered not satisfactory.

Trigliceridemia de jejum e pós-prandial em mulheres: avaliação de co-morbidade, fatores de risco e circunferência abdominal / Fasting and postprandial triglyceridemia in women: comorbid, risk factors and abdominal circumference evaluation

A prevalência da obesidade continua a aumentar. A adiposidade abdominal parece exercer papel crítico no desenvolvimento e na progressão de fatores de risco cardiometabólicos. O estudo procurou avaliar a presenta de co-morbidade, bem como a associação possível entre os valores da circunferência abdominal e a trigliceridemia em jejum e pós-prandial em mulheres.

The prevalence of obesity is growing. Abdominal obesity seems to have a critical role in the development and progression of cardiometabolic risk factors. The objective of the study is to assess the frequency of comorbidities and the possible association betweem abdominal waist and fasting and nonfasting triglycerides.

Nutritional status, especially body mass index, from birth to adulthood and lung function in young adulthood.

OBJECTIVE: The study assessed the impact of body mass index (BMI) at birth, infancy, and adulthood, and waist circumference on lung function. METHODS: Using a longitudinal design 1221 Chilean young adults were studied. A standardized respiratory questionnaire was used. Forced expiratory volume in 1 s (FEV(1)), forced vital capacity (FVC), height, weight and waist circumference were measured. Data at birth and at 1 year were obtained from clinical notes. RESULTS: Males with a BMI > or = 30 and women with a BMI < 20 had a lower FEV(1) (-230 mL, 95% CI -363 to -98; -106 mL, 95% CI -211 to -0.18, respectively). In both sexes those with a BMI 20-25 had the highest FEV(1) and FVC. In males there was a negative association between waist circumference and FEV(1) and FVC while in women the middle tertile had the highest FEV(1) and FVC. There was an association between birthweight and BMI at birth, and FEV(1) in men, when unadjusted for other measurements. CONCLUSIONS: BMI and waist circumference in adulthood make a greater impact on lung function in adulthood than anthropometric measurements at birth and infancy. Proxy measures of fatness in adulthood reduce lung function, but the pattern between fatness and lung function by sex may be different.

[Association between abdominal circumference and hypertension among women: the Pró-Saúde Study]. / Associação entre circunferência abdominal e hipertensão arterial em mulheres: Estudo Pró-Saúde.

This study aimed to estimate the prevalence of hypertension according to levels of abdominal circumference (AC) and body mass index (BMI, expressed as kg/m(2)) among public employees at a university in Rio de Janeiro, Brazil. Cross-sectional data were obtained for 1,743 non-pregnant women aged 24-69 years participating in the Pró-Saúde Study. Underweight women and those with BMI > 35 kg/m(2) were excluded. Hypertension was defined as systolic blood pressure >140 mmHg or diastolic > 90 mmHg or the use of anti-hypertensive drugs. Age-adjusted prevalence rates for hypertension were calculated considering two strata of AC (normal: < 88 cm; high: > 88 cm) and three levels of BMI (normal: 18.5-24.9 kg/m(2); overweight: 25.0-29.9 kg/m(2); and obesity I: 30.0-34.9 kg/m(2)). Among normal-weight women, participants with high AC showed a two-fold higher prevalence of hypertension as compared to those with AC < 88 cm (18% vs. 8%, p < 0.05). Routine measurement of AC, in addition to BMI, could contribute to early identification of hypertension in women.

A prospective study of waist circumference and body mass index in relation to colorectal cancer incidence.

OBJECTIVES: To study the association between waist circumference and colorectal cancer, and whether it is independent of body mass index (BMI). METHODS: Between 1997 and 2005, 953 incident colorectal cancer cases (546 men and 407 women) were identified among 95,151 participants (44,068 men and 51,083 women) from the Cancer Prevention Study-II Nutrition Cohort. RESULTS: Waist circumference was associated with increased colorectal cancer incidence in both men (multivariable adjusted rate ratio (RR) 1.68, 95% confidence interval (CI) 1.12-2.53 for waist circumference > or =120 cm compared to <95 cm, p trend = 0.006) and women (RR 1.75, 95% CI 1.20-2.54 for > or =110 compared to <85 cm, p trend = 0.003). High levels of BMI were also associated with increased risk. After adjustment for BMI, waist circumference remained associated with a nonstatistically significant increase in colorectal cancer incidence in both men (RR 1.41, 95% CI 0.81-2.45 for > or =120 compared to <95 cm, p trend = 0.10) and women (RR 1.48, 95% CI 0.89-2.48 for > or =110 compared to <85 cm, p trend = 0.13). CONCLUSIONS: Our results confirm that waist circumference is associated with increased colorectal cancer incidence, possibly partially independent of BMI.

Association between GERD-related erosive esophagitis and obesity.

BACKGROUND AND OBJECTIVES: To date, many studies have reported on the association of obesity with gastroesophageal reflux disease (GERD), although none of these have been systematic. In light of this, we conducted this study to examine the association of obesity and GERD. SUBJECTS AND METHODS: A total of 3363 patients underwent gastroscopy at Hanyang University Health Promotion Center. Among these patients, we prospectively examined patients who were diagnosed with GERD-related erosive esophagitis on endoscopy. RESULTS: Multivariate analysis showed that the significant risk factors were waist-to-hip ratio (WHR), hiatal hernia, body mass index (BMI), and smoking. As compared with patients who had a WHR less than 0.8, the multivariate odds ratio for erosive esophagitis were 4.055 for a WHR more than 1.0 and 2.316 for a WHR of 0.8 to 1.0. As compared with patients who had a BMI of 20 to 22.5, the multivariate odds ratio for erosive esophagitis was 3.308 (95% confidence interval, 1.792 to 6.107) for a BMI greater than 30. CONCLUSIONS: Obesity, especially abdominal obesity, was the significant risk factor for erosive esophagitis.

Is central obesity a better discriminator of the risk of hypertension than body mass index in ethnically diverse populations?

OBJECTIVE: To compare the performance of body mass index (BMI) against waist circumference, waist: hip ratio (WHR) and waist: height ratio in the discrimination of hypertension in ethnically diverse populations. METHODS: Meta-analysis of 19 cross-sectional studies. MAIN OUTCOME MEASURES: Discrimination of hypertension (SBP/DBP > or = 140/90 mmHg) was adjudicated from Receiver Operating Characteristic curves; optimum thresholds were defined as those that maximized sensitivity plus specificity. RESULTS: Irrespective of which measure of overweight was used, the strength of the association with blood pressure was consistently greater among Asians compared with Caucasians or Pacific Islanders; however, in all regions, and for all anthropometric measures, the increment in blood pressure, and the additional risk of hypertension, were broadly similar for the same relative increment in each of the four measures. Optimum thresholds varied by region; WHR was the most consistent between the regions, with thresholds of 0.92-0.94 for men and 0.80-0.88 for women. No anthropometric variable was systematically better than others at the discrimination of hypertension. CONCLUSIONS: Blood pressure is similarly associated with each of the four measures of overweight chosen, but the associations were stronger among Asians. WHR has advantages in terms of consistency of thresholds for hypertension across ethnic groups in the Asia-Pacific.
