Abstract：

Objective To explore the impact of obesity level and the level change in childhood on hypertension incidence.Methods A perspective cohort study was conducted.As part of Beijing Child and Adolescent Metabolic Syndrome Study,2189 aged 6-16 year non-hypertensive children was followed up in December,2010.In this study,height,weight,waist circumference (WC) and blood pressure was measured at follow-up,and body mass index (BMI) and WC was respectively used to assess overweight,obesity and abdominal obesity.Non-conditional logistic regression was used to evaluate the association between baseline obesity status, change of obesity status and hypertension incidence. OR and 95%CI were computed in the model using obese status as dummy variable and hypertension at follow up visit as dependent variable.Results The total hypertension incidence of 1184 subjects during 6 years follow-up was 19.9%(236/1184).The hypertension incidence in male (23.2%,149/643) was higher than that in female (16.1%,87/541) (χ2=9.257,P=0.002).The hypertension incidence of non-overweight,overweight and obese children at baseline was 8.7%(45/519),19.3%(35/181) and 32.4%(156/484)respectively (χ2=9.332,P<0.001),and the incidence of non-obese and abdominal obese children at baseline was respectively 10.3%(63/613) and 30.7%(173/567) (χ2=77.753,P<0.001).Hypertension incidence in the baseline obesity group was higher than the non-overweight (BMI:OR=4.9,95%CI:3.4-7.0) and non-obese group (WC:OR=3.9,95%CI: 2.8-5.3).The hypertension incidence increased with the follow-up BMI/WC level,based on the same baseline level of BMI and WC.The hypertension risk increased to 0.21 and 0.07 times respectively with elevation of baseline BMI level by 1 kg/m2 and WC level by 1 cm,and OR(95%CI) were 1.21(1.16-1.26) and 1.07(1.05-1.09),respectively.Similarly,the hypertension risk increased 0.16 and 0.05 times respectively with the elevation of BMI level change by 1 kg/m2 and 1 cm,and OR (95%CI) were 1.16(1.11-1.22) and 1.05(1.03-1.07),respectively.Conclusion Obesity and increased obesity level change in childhood can increase the risk of incident hypertension.

  目的   探讨天津市宝坻区60岁及以上老年居民的体质指数(body mass index, BMI)、腰围(waist circumference, WC)以及腰围身高比(waist-to-height ratio, WHtR)与高血压患病率的关联。   方法   本研究对2018年4-5月参加天津市宝坻区口东卫生院体检的老年人(≥60岁)进行问卷调查和体格检查。采用分层分析和logistic回归分析BMI与WC(或WHtR)对高血压的联合作用和交互作用。   结果   共邀请1 692人, 1 417人(83.75%)参与本研究。老年人群的高血压患病率为46.36%、BMI超重和肥胖者占66.50%、WC中心型肥胖者占74.66%、WHtR超重和肥胖者占75.38%。与BMI或WC正常相比, BMI超重(OR=1.65, 95% CI:1.19~2.30)和肥胖(OR=3.41, 95% CI:2.23~5.20)及WC中心型肥胖(OR=1.49, 95% CI:1.00~2.23)均增加高血压的患病风险。BMI联合WC超重/肥胖(OR=2.49, 95% CI:1.78~3.46), 或BMI联合WHtR超重/肥胖(WHtR超重: OR=2.05, 95% CI:1.41~2.99;WHtR肥胖: OR=2.37, 95% CI:1.50~3.76)的患病风险高于后者单独作用的风险(WC超重/肥胖: OR=1.39, 95% CI:0.90~2.15;WHtR超重: OR=1.02, 95% CI:0.62~1.66;WHtR肥胖: OR=1.44, 95% CI:0.55~3.81)。   结论   三项指标中, BMI与高血压患病的关联性最强, 且BMI超重/肥胖增强WC(或WHtR)与高血压的关联, 提示控制BMI相关体重指标在正常范围内有助于预防和控制高血压。     

不同肥胖指标与MS其他组分患病风险研究

目的分析体质指数(BMI)、腰围(WC)、腰围/身高比值(WHtR)3个肥胖指标与MS及其他组分的相关性。方法选取2008年参加健康体检的延吉市某社区居民,进行问卷调查、血压测量、体格检查及生化指标检测。对资料完整的886例对象按照不同的BMI、WC水平进行分层,比较分析代谢异常组分患病情况。对WHtR指标与MS其他组分异常数量的相关性进行分析,并寻找适合的切点,分析其对MS的患病风险。结果调查对象中肥胖程度比较严重,且各项指标存在性别差异;各项代谢异常患病率均与BMI和WC有关,两者均异常时,各项表示代谢性健康风险的OR值明显高于BMI与WC各单项异常组(P﹤0.01),但仅有腹型肥胖时,其OR值均高于BMI超重而WC正常者;WHtR与代谢异常数量之间存在正相关(r=0.479,P﹤0.01),当WHtR超过0.50时,个体MS患病危险度显著增加(OR:1.564,95%CI:1.046～1.896,P﹤0.01)。结论 BMI和WC异常可增加代谢异常疾病的患病风险,WHtR是较好代表中心性肥胖的指标,在防治MS其他组分时应将体脂增多同时伴有脂肪分布异常者列为重点高危人群。     

Skinfold thickness, body mass index, and fatal coronary heart disease: 30 year follow up of the Northwick Park heart study

STUDY OBJECTIVE: To examine the effect of baseline body mass index (BMI) and skinfold thickness (ST) on fatal coronary heart disease (CHD) and all cause mortality after 30 years of follow up. DESIGN: Prospective cohort study. SETTING: Northwick Park heart study (NPHS) designed to investigate the role of haemostatic variables on CHD. PARTICIPANTS: 1511 men and 691 women enrolled in NPHS aged 40 to 64 years at entry. MAIN RESULTS: Baseline BMI (kg/m(2)) and forearm, triceps, subscapular, and suprailiac skinfolds ST (mm) were measured. Cox regression was used to calculate hazard ratios for fatal CHD and total mortality for each standard deviation unit increase in obesity adjusting for age, smoking status, total cholesterol, systolic blood pressure, fibrinogen, and factor VII activity. Subjects experienced 250 fatal CHDs and 819 all cause deaths over 30 years (median: 26 years; IQR: 22-28 years). Among men, only BMI (RR = 1.29, 95%CI = 1.12 to 1.49) significantly increased the risk of fatal CHD. Among women, BMI (RR = 1.48, 95%CI = 1.07 to 2.06), as well as, subscapular (RR = 1.65, 95%CI = 1.19 to 2.30), forearm (RR = 1.46, 95%CI = 1.08 to 1.97), and triceps (RR = 1.63, 95%CI = 1.12 to 2.39) skinfolds were predictive of fatal CHD. None of the estimates for all cause mortality were significant except for subscapular skinfold in women (RR = 1.20, 95%CI = 1.02 to 1.42). There was no evidence of interaction between obesity and sex for fatal CHD or all cause death. The effect of obesity on fatal CHD or all cause deaths does not seem to be mediated substantially by cholesterol, systolic blood pressure, or haemostatic variables. CONCLUSIONS: BMI is an important risk factor for fatal CHD where its prognostic significance remains after up to 30 years of follow up.     

Body mass index, waist circumference, and risk of coronary heart disease: a prospective study among men and women

OBJECTIVE: The purpose of the study was to assess the risk of CHD associated with excess weight measured by BMI and waist circumference (WC) in two large cohorts of men and women. DESIGN, SETTING, SUBJECTS: Participants in two prospective cohort studies, the Health Professionals Follow-up Study (N = 27,859 men; age range 39-75 years) and the Nurses' Health Study (N = 41,534 women; 39-65 years) underwent 16-year follow-up through 2004. RESULTS: 1,823 incident cases of CHD among men and 1,173 cases among women were documented. Compared to men with BMI 18.5 to 22.9 kg/m2, those with a BMI > 30.0 kg/m2 had a multivariate-adjusted RR of CHD of 1.81 (95% CI 1.48 - 2.22). Among women, those with a BMI > 30.0 kg/m2 had a RR of CHD of 2.16 (95% CI 1.81 - 2.58). Compared to men with a WC < 84.0 cm, those with WC of greater than 102.0 cm had a RR of 2.25 (95% CI 1.77 - 2.84). Among women, the RR of CHD was 2.75 (95% CI 2.20 - 3.45) for those with WC of greater than 88.0 cm. CONCLUSIONS: In these analyses from two large ongoing prospective cohort studies, both BMI and WC strongly predicted future risk of CHD. Furthermore, WC thresholds as low as 84.0 cm in men and 71.0 cm in women may be useful in identifying those at increased risk of developing CHD. The findings have broad implications in terms of CHD risk assessment in both clinical practice and epidemiologic studies.     

Prospective study of optimal obesity index cutoffs for predicting development of multiple metabolic risk factors: the korean genome and epidemiology study

Background: In this prospective cohort study, we estimated the risk of developing more than 1 metabolic risk factor, using different obesity indices. In addition, we investigated the relative usefulness of the obesity indices for predicting development of such risk factors and calculated optimal cutoffs for the obesity indices.Methods: The cohort comprised 10 038 representative residents of a small city and a rural county who were recruited in 2001-2002. Follow-up examinations were conducted every 2 years. Among the 3857 participants without metabolic syndrome at baseline, 1102 new cases occurred during the 6-year follow-up. Receiver operating characteristic (ROC) curves for the obesity indices were plotted to compare the usefulness of the obesity indices.Results: The numbers of new cases of multiple metabolic risk factors among people in the highest quintiles of body mass index (BMI), waist circumference (WC), waist-hip ratio (WHR), and waist-height ratio at the baseline examination were 2 to 3 times those in the lowest quintiles. The area under the ROC curve for WHR was significantly higher than that for BMI. The optimal BMI cutoff was 24 kg/m(2) in men and women, and the optimal WC cutoffs were 80 cm and 78 cm in men and women, respectively.Conclusions: Both overall obesity and central obesity predicted risk of developing multiple metabolic risk factors, and WHR appeared to be a better discriminator than BMI. To prevent development of metabolic diseases among Koreans, it might be useful to lower the cutoff for abdominal obesity, as defined by WC.

目的 分析我国成年人BMI和腰围与缺血性卒中发病风险的关联。方法 从2010年中国慢性病监测项目选取60个监测点人群（城市监测点25个、农村监测点35个）作为本次研究对象,共计36 632人。将2010年中国慢性病监测项目数据作为基线数据。2016-2017年对该60个监测点人群进行随访,实际完成者27 762人。采用Cox比例风险回归模型分析不同人群BMI和腰围与缺血性卒中发病风险比,敏感性分析将死亡者和高胆固醇血症者剔除。结果 共纳入26 907人进入分析,随访期间观察到缺血性卒中事件1 128例（男性491例,女性637例）。调整相关混杂因素后,以BMI正常/腰围正常者为参照,全人群和男性具有CVD危险因素人群,BMI正常/腹型肥胖组、超重/腹型肥胖组和肥胖/腹型肥胖组缺血性卒中发病风险分别增加50%（HR=1.50,95% CI：1.07~2.08）、51%（HR=1.51,95% CI：1.20~1.91）、46%（HR=1.46,95% CI：1.09~1.96）和63%（HR=1.63,95% CI：1.12~2.38）、56%（HR=1.56,95% CI：1.20~2.03）、45%（HR=1.45,95% CI：1.05~2.01）,超重/腰围正常组未见发病风险增加;女性全人群和女性CVD危险因素人群,超重/腹型肥胖组和肥胖/腹型肥胖组发病风险分别增加40%（HR=1.40,95% CI：1.15~1.72）、46%（HR=1.46,95% CI：1.16~1.83）和35%（HR=1.35,95% CI：1.08~1.69）、30%（HR=1.30,95% CI：1.01~1.67）,超重/腰围正常组和BMI正常/腹型肥胖组未见发病风险增加。敏感性分析结果未见变化。结论 在男性人群中,超重/肥胖且腹型肥胖或单纯腹型肥胖缺血性卒中发病风险增加;在女性人群中,超重/肥胖且腹型肥胖发病风险增加;提示在控制体重预防缺血性卒中,应将BMI和腰围进行结合来评价人群肥胖情况。     

Comorbidity of overweight and obesity in a nationally representative sample of German adults aged 18-79 years

ABSTRACT: BACKGROUND: Overweight has increased in many countries over the past 20 years and excessive body weight is an established risk factor for adverse health outcomes and chronic diseases. This study aimed to determine comorbidity associated with overweight and obesity in a nationally representative sample of German adults. METHODS: In the German National Health Interview and Examination Survey 1998 standardized measures of body weight, height and waist circumference (WC) were obtained for 7,124 men and women 18 to 79 years of age. Information on pre-existing health conditions, health-related behaviors, and sociodemographic characteristics was collected using physician-administered computer-assisted interviews and self-administered questionnaires. World Health Organization (WHO) cut-off criteria were applied to define overweight (BMI: 25.0-29.9 kg/m2) and obesity (BMI [GREATER-THAN OR EQUAL TO]30.0 kg/m2) and abdominal obesity (men: WC [GREATER-THAN OR EQUAL TO]102 cm; women: WC [GREATER-THAN OR EQUAL TO]88 cm). RESULTS: The crude prevalence of persons with cardio metabolic risk factors, diabetes mellitus, cardiovascular disease (CVD), gall bladder disease, and osteoarthritis showed a significant stepwise increase from the lowest to the highest BMI category in both sexes. In multiple logistic regression models adjusting for age, social status, and smoking, significant associations with overweight and obesity persisted for cardio metabolic risk factors and osteoarthritis. For example, obese persons had a three- to fourfold higher chance of having any cardio metabolic risk factor compared to normal weight persons (odds ratio (OR) = 4.07, 95% CI: 3.16-5.25 for men; OR = 3.40 (2.60-4.46) for women). Only in women, overweight and obesity as well as abdominal obesity, independent of BMI category, were significantly and consistently associated with diabetes (overweight: OR = 1.85 (1.03-3.30); obesity: OR = 2.94 (1.63-5.31); abdominal obesity: OR = 1.44 (1.08-1.92) and gall bladder disease (overweight: OR = 1.65 (1.22-2.25); obesity: OR = 3.06 (2.26-4.14); abdominal obesity: OR = 1.73 (1.25-2.39)). CONCLUSION: Current estimates of disease burden underline the public health importance and clinical relevance related to overweight and obesity and needs to take into account comorbidity aspects.     

体重指数、腰围与代谢性健康风险的关系

目的比较体重指数（BMI）、腰围（WC）与代谢性健康风险的大小。方法对苏州市和常熟市两个社区的江苏省多代谢异常和代谢综合征（MS）防治研究中，经济发达地区基线资料的1604例对象按BMI和WC分组，在正常体重（BMI：18～23．9）、超重（BMI：24～27．9）、肥胖（BMI≥28）类别中，计算高血压、高血糖、血脂异常的相对危险度（RR），并对WC类别中腹型肥胖（男≥85cm，女≥80cm）和WC正常个体进行比较。结果无论是男性还是女性，其高血压、糖脂代谢各项指标以及MS的罹患率均与BMI和WC相关，控制混杂因素后，这样的相关性依然存在；但仅BMI超重时，各项表示代谢性健康风险的aRR值基本上都低于BMI超重合并腹型肥胖的aRR值；男、女性BMI正常但有腹型肥胖时，均较BMI超重而WC正常者的健康风险高。结论WC在表示代谢性健康风险方面比BMI更为有效。
