    BACKGROUND & AIMS: INTRODUCTION:Abnormal ankle-brachial index (ABI) is associated with increased morbidity and mortality in hemodialysis patients. However, whether the decrease in ABI over time carries the prognostic value is unknown. The aim of this study was to assess whether the decrease in ABI over time was a good predictor of poor cardiovascular (CV) prognosis in hemodialysis patients. METHODS:This study enrolled 234 routine hemodialysis patients and 173 patients completed the follow-up. The ABI was measured by an ABI-form device at baseline and at the first year follow-up. The ΔABI was defined as ABI measured at the first year follow-up minus ABI measured at baseline. Progressors of ABI were defined as patients with ΔABI < -0.3. CV events were defined as CV death, hospitalization for unstable angina, nonfatal myocardial infarction, hospitalization for arrhythmia, hospitalization for congestive heart failure and stroke. RESULTS:The follow-up period was 37.8 ± 11.1 months. In the multivariate analysis, progressors of ABI (hazard ratio, 2.71; 95% confidence interval, 1.10-6.68, P = 0.03), decreased albumin and increased high-sensitivity C-reactive protein were associated with increased CV events. CONCLUSIONS:This longitudinal study showed ΔABI < -0.3 was independently associated with an increase in CV events. Hence, a great decrease in ABI over time might be a useful indicator of poor CV prognosis in hemodialysis patients.

    BACKGROUND & AIMS: BACKGROUND:Individuals with HIV disease often must adhere to complex medication regimens. To date, regimen complexity has not been examined in the literature using standardized procedures incorporating all important elements of antiretroviral (ARV) regimens. OBJECTIVE:This article presents a novel method of quantifying regimen complexity using objective criteria addressing the factors that may complicate adherence to ARV regimens. METHODS:Part 1 of this article describes the development of the Antiretroviral Regimen Complexity (ARC) Index scoring system. Based on input from pediatric and adult patients, caregivers of pediatric patients, and health care professionals, this comprehensive system includes the number of medications, dosing schedules, administration methods, special instructions, and required preparations associated with ARV regimens. Weights are applied for each of these factors to produce an overall score representing the regimen's level of complexity. Part 2 of this article presents reliability and validity data for the system. RESULTS:The ARC Index demonstrates excellent test-retest and interrater reliability as well as strong construct and discriminant validity. An on-line version of this system minimizes computation errors. CONCLUSIONS:Although modifications may be necessary for patients requiring nonstandard dosing instructions, preliminary evidence supports the utility of this measure as a reliable and valid indicator of the complexity of antiretroviral treatment regimens.

    BACKGROUND & AIMS: :It is unclear whether overweight but otherwise healthy boys with delayed puberty have a variation of constitutional delay of growth and maturation (CDGM) or a different etiology for their pubertal delay. To characterize better this group of boys and investigate whether their growth pattern distinguishes them from boys with typical CDGM, growth data were analyzed in eight overweight (BMI SDS > or = 85th percentile) and 37 non-overweight (BMI SDS <85th percentile) boys with delayed puberty. Primary outcome measures included predicted height (PH) and adult height (AH). At diagnosis of delayed puberty, the overweight boys had less delayed bone ages (chronological age [CA] - bone age [BA] = 1.2 +/- 1.0 vs 2.5 +/- 1.1 years, p <0.01), greater height SDS for CA (-0.5 +/- 0.7 vs -2.4 +/- 0.8, p <0.001), and greater height SDS for BA (0.6 +/- 0.9 vs -0.4 +/- 1.1, p <0.05). PH for the overweight boys exceeded their mid-parental height (MPH) by 5.0 +/- 7.2 cm while non-overweight boys were predicted to fall below their MPH by 2.8 +/- 6.3 cm (p <0.01). Available AH data corroborated the differences in PH, with a trend for overweight boys to have greater height relative to their MPH than the non-overweight boys. These observations suggest that in the context of delayed puberty, being overweight may modulate adult height and/or that the etiology of delayed puberty in overweight boys may differ from typical CDGM.
    背景与目标: : 尚不清楚青春期延迟的超重但健康的男孩是否存在生长和成熟的体质延迟 (CDGM) 或青春期延迟的不同病因。为了更好地描述这一组男孩,并调查他们的生长模式是否将他们与典型CDGM男孩区分开,对8名超重 (BMI SDS> 或 = 85百分位) 和37名非超重 (BMI SDS <85百分位) 青春期延迟男孩的生长数据进行了分析。主要结局指标包括预测身高 (PH) 和成人身高 (AH)。在诊断青春期延迟时,超重男孩的骨龄延迟较少 (按时间顺序年龄 [CA] -骨龄 [BA] = 1.2/- 1.0 vs 2.5/- 1.1岁,p <0.01),CA的更高高度SDS (-0.5 +/- 0.7 vs -2.4 +/- 0.8,p <0.001),BA的更高高度SDS (0.6 +/- 0.9 vs -0.4 +/- 1.1,p <0.05)。超重男孩的ph值超过其父母中等身高 (MPH) 5.0 +/-7.2厘米,而非超重男孩预计将低于其MPH 2.8 +/-6.3厘米 (p <0.01)。可用的AH数据证实了PH的差异,超重男孩的身高相对于其MPH的趋势比非超重男孩更大。这些观察结果表明,在青春期延迟的情况下,超重可能会调节成人身高和/或超重男孩青春期延迟的病因可能与典型的CDGM不同。

    BACKGROUND & AIMS: STUDY OBJECTIVE:The aim was to examine whether a high intake of aluminium containing antacids is a risk for Alzheimer's disease. DESIGN:The mortality from dementia (1970-87), coded from death certificates as underlying or contributory cause of death, was compared with national rates in a cohort of patients who had surgery for gastroduodenal ulcer disease between 1911 and 1978. SETTING:Patient data were obtained from patient records from major hospitals in western Norway. PARTICIPANTS:4179 patients were identified who met the study criteria, which included having had a documented stomach operation, having a reliably identifiable personal number, and being alive on Jan 1, 1970. MEASUREMENTS AND MAIN RESULTS:The standardised mortality ratio for dementia was 1.10 (95% CI 0.85-1.40, n = 64) for all patients, while for patients operated on in the period 1967-78 it was 1.25 (95% CI 0.66-2.13, n = 13). CONCLUSIONS:As the majority of patients operated on after 1963 have probably been heavy consumers of aluminium containing antacids, the study provides meager evidence that a high intake of aluminium is an important risk factor for Alzheimer's disease, the major cause of dementia. However, the possibility of a raised mortality from Alzheimer's disease cannot be ruled out due to probable misclassification both in diagnosis and exposure. In addition, the observation period may have been too short to detect an effect since the latent period for Alzheimer's disease may be very long.

    BACKGROUND & AIMS: Stress ulcer prophylaxis protects against clinically important gastrointestinal bleeding and has gained widespread use. This study compares the efficacy of omeprazole to ranitidine for this indication. This was a prospective, randomized clinical trial. Sixty-seven high-risk patients were randomized to receive either ranitidine 150 mg (N = 35) intravenously daily or omeprazole 40 mg (N = 32) daily orally or by nasogastric route. Patients were monitored for clinically important bleeding. There was no statistically significant difference between treatment groups in the number of patients enrolled, gender, race, or age. The study groups were comparable in regard to the severity of illness based on their similar APACHE II score, duration of ICU stay, duration of ventilator dependence, and mortality rate. A significant difference was found only in regard to the number of risk factors per patient. The ranitidine-treated group had 2.7 risk factors per patient while the omeprazole-treated group had 1.9 (P < 0.05). Eleven patients (31%) given ranitidine and two patients (6%) given omeprazole developed clinically important bleeding (P < 0.05). Nosocomial pneumonia developed in five patients (14%) receiving ranitidine and one patient (3%) receiving omeprazole (P > 0.05). We conclude that oral omeprazole is safe, effective, and clinically feasible for stress ulcer prophylaxis.

    背景与目标: 预防应激性溃疡可预防临床上重要的胃肠道出血,并已获得广泛应用。本研究比较了奥美拉唑与雷尼替丁对该适应症的疗效。这是一项前瞻性随机临床试验。67名高危患者被随机分配,每天静脉注射雷尼替丁150 mg (N = 35) 或每天口服奥美拉唑40 mg (N = 32) 或通过鼻饲途径。监测患者的临床重要出血情况。治疗组在入组患者人数,性别,种族或年龄方面没有统计学上的显着差异。基于相似的APACHE II评分,ICU停留时间,呼吸机依赖持续时间和死亡率,研究组在疾病严重程度方面具有可比性。仅在每位患者的危险因素数量方面发现显着差异。雷尼替丁治疗组每个患者有2.7危险因素,而奥美拉唑治疗组有1.9 (P <0.05)。11名患者 (31%) 接受雷尼替丁治疗,2名患者 (6%) 接受奥美拉唑治疗,出现临床上重要的出血 (P <0.05)。5例接受雷尼替丁治疗的患者 (14% 例) 和1例接受奥美拉唑治疗的患者 (3% 例) 发生院内肺炎 (P> 0.05)。我们得出的结论是,口服奥美拉唑对预防应激性溃疡是安全,有效且临床上可行的。

    BACKGROUND & AIMS: :The effect of body mass index (BMI) and obesity on apolipoprotein (apo) A-I levels and kinetics was examined by gender. Apo A-I kinetics were determined with a primed, constant infusion of deuterated leucine in the fed state in 19 men and 13 postmenopausal women. Compared with nonobese men, nonobese women had a higher level of high-density lipoprotein cholesterol (HDL-C) and apo A-I due to a 48% higher apo A-I production rate (PR) (P = .05). Obesity had no significant effects on apo A-I kinetics in women. In contrast, compared with nonobese men, obese men had a 9% lower apo A-I level due to a 64% higher fractional catabolic rate (FCR) partially offset by a 47% higher PR. Obese women had a 52% higher HDL-C than obese men (50 vs 33 mg/dL, respectively; P = .012), a finding related to the faster apo A-I FCR in obese men. BMI was directly correlated with apo A-I FCR (r = 0.84, P < .001) and PR (r = 0.79, P < .001) in men but not in women. Sixty-two percent of the variability in PR and 71% of the variability in FCR were due to BMI in men and only 3% and 23%, respectively, in women. In conclusion, BMI has a significant effect on apo A-I PR and FCR in men but not in women.
    背景与目标: : 通过性别检查了体重指数 (BMI) 和肥胖对载脂蛋白 (apo) A-I水平和动力学的影响。在19名男性和13名绝经后女性中,通过在进食状态下持续不断地输注氘代亮氨酸来确定Apo A-I动力学。与非肥胖男性相比,非肥胖女性的高密度脂蛋白胆固醇 (hdl-c) 和apo a-I水平较高,原因是apo A-I的生产率 (PR) 48% 较高 (P = .05)。肥胖对女性的apo A-I动力学没有显着影响。相反,与非肥胖男性相比,肥胖男性的apo a-I水平9% 较低,这是由于64% 较高的分解代谢率 (FCR) 部分被47% 较高的PR抵消。肥胖女性的hdl-c比肥胖男性高52% (分别为50 vs 33 mg/dL; P = .012),这一发现与肥胖男性的apo a-I FCR更快有关。BMI与男性的apo A-I FCR (r = 0.84,P <.001) 和PR (r = 0.79,P <.001) 直接相关,而女性则不相关。PR变异性的60 2% 和FCR变异性的71% 是由于男性的BMI,而女性分别只有3% 和23%。总之,BMI对男性的apo a-I PR和FCR有显着影响,而女性则没有。

    BACKGROUND & AIMS: :Hepatocellular carcinoma (HCC) is a common malignancy and the main cause of mortality in patients with chronic liver diseases. This study reports the inhibitory effect of boron on HCC induced in rats by administering thioacetamide (TAA) (0.03%) in drinking water for 400days. Boron (4mg/kg body weight) was administered orally after induction of carcinoma. Treatment was continued for 122days, and cell proliferation, histology and biochemistry of treated and control group of rats were studied. Proliferating cell nuclear antigen (PCNA), and [(3)H]-thymidine incorporation, which increased in rats exposed to carcinogen, significantly decreased after boron treatment. PCNA index decreased from 80 in HCC rats to 32 after boron treatment. In the control group, it was 20. Boron caused a dose-dependent decrease in carcinogen-induced [(3)H]-thymidine uptake by the rat hepatocyte. It could partially reverse the activity of selected biochemical indicators of hepatic damage, oxidative stress, selenium and serum retinol, which are depleted in liver cancer, and improved overall health of animal. The study implicates the elevated levels of mammalian molybdenum Fe-S containing flavin hydroxylases, which increase the free radical production and oxidative stress, consequently causing increased hepatic cell proliferation in HCC, and reports boron to ameliorate these changes in liver cancer.

    BACKGROUND & AIMS: :Inflammation affects the reliability of ferritin. The serum level of transferrin receptor protein (sTfR) represents true demand of iron in the body. This study attempts to identify levels of sTfR and correlate the trends of sTfR/ferritin index with BMI in the population of Karachi. 132 gender matched volunteers between the ages of 20-60 years were recruited for this cross-sectional study. BMI was calculated using the formula: (weight in kg / height in m2). Following groups were made according to South Asian criteria of BMI; Group A: normal weight (18.0-22.9 kg/m2), Group B: overweight (23.0-24.9 kg/m2), Group C: obese (>25.0 kg/m2). Serum ferritin, sTfR and CRP levels were determined using ELISA kits. Statistical comparisons were performed using Mann Whitney U and Spearman's rank correlation, where p<0.05 was considered significant. The results identified increased in TIBC, sTfR, ferritin and CRP in obese as compared to normal weight individuals (p<0.001). sTfR/ferritin ratio was 0.822 which signifies increased risk of acute myocardial infarction in group C. Serum iron (r=-0.359,p=0.004) showed negative correlation with BMI while serum ferritin (r=0.237,p< 0.001) and sTfR (r=0.263,p= 0.036) levels were positively associated to BMI. This study highlights a novel finding that sTfR is most likely a better clinical measure of iron status in inflammatory conditions as its expression is effected by erythropoiesis and not by inflammation. Risk of Acute myocardial infarction can also be predicted by increased sTfR/ferritin ratio.

    BACKGROUND & AIMS: PURPOSE:To investigate the effect of the glycemic index (GI) of pre-exercise snack bars on substrate utilization during subsequent moderate intensity exercise. METHODS:Fourteen male participants (Age: 27 ± 5 yr; BMI: 22.5 ± 2.7 kg m(-2); [Formula: see text]: 48.7 ± 6.1 mL kg(-1 )min(-1)) completed two trials in a randomized and counterbalanced crossover design. Two iso-caloric snack bars with different GI values (20, LGI versus 68, HGI) were provided to the participants. Ninety minutes later, all participants completed 45 minutes of ergometer cycling at 65% [Formula: see text]. Substrate utilization was measured using indirect calorimetry. RESULTS:During exercise, higher fat oxidation and lower carbohydrate (CHO) oxidation were observed in the LGI trial (LGI versus HGI: CHO, 87.3 ± 20.1 versus 99.2 ± 19.0 g, p < 0.05; Fat, 15.0 ± 5.8 versus 9.7 ± 7.0 g, p < 0.05). CONCLUSION:Compared with an iso-caloric HGI snack bar, pre-exercise LGI snack bar consumption may facilitate a shift of substrate utilization from CHO to fat during subsequent moderate intensity exercise.

    BACKGROUND & AIMS: OBJECTIVE:To assess the use of the International Index of Erectile Function (IIEF), routinely used in patients being treated for localized prostate cancer, including potency-preserving, nerve-sparing radical prostatectomy (RP), as many patients complain that the results of the IIEF over 4 weeks before RP are not representative. PATIENTS AND METHODS:The study included 123 consecutive patients (mean age 64.6 years, range 52-78) who had endoscopic-extraperitoneal RP and who completed the IIEF. The interval between the diagnosis of the disease and surgery was >4 weeks in all. The patients completed the same questionnaire referring to the last 4 weeks before their prostate biopsy, as a modified index of their sexual status (IIEFm and EFm). RESULTS:The clinical stage of disease was cT1c (34.9%), cT2a (49.5%), cT2b (5.7%) and cT2c (9.9%) before RP. The mean IIEF score was 42.8 and the mean EF domain score was 16.9; the mean IIEFm was 54.9 and the EFm domain score was 23.7. All the differences were statistically significant (P < 0.001). CONCLUSION:The IIEF questionnaire scores are influenced by many factors. Depression after a diagnosis of cancer, and the prostate biopsy-related symptoms, e.g. prostatitis, perineal pain and haemospermia, might compromise the patients' well-being and libido, and thus affect the IIEF scores before RP. We therefore suggest using the IIEFm and EFm scores before prostate biopsy to assess the patients' sexual status before any treatment for localized prostate cancer.

    BACKGROUND & AIMS: OBJECTIVE:Cross-sectional data suggest that obesity, particularly central obesity, may be associated with decreased production of sex steroid hormones in men. However, longitudinal hormone data on men in relation to obesity status are limited. Previous studies have not consistently demonstrated whether sex steroids are associated specifically to body mass index or to measures of central obesity. Our objective was to examine the relation of obesity (body mass index > 30 kg/m2), and of central obesity (waist circumference > 100 cm or waist to hip ratio > 0.95) to longitudinal change in sex steroid hormones in men. DESIGN:Prospective follow-up of a population-based sample of men in Boston. PATIENTS:Nine hundred forty-two (942) men in the Massachusetts Male Ageing Study with complete anthropometry and hormone data at baseline (1987-1989, ages 40-70) and follow-up (1995-1997). MEASUREMENTS:Free and total testosterone (FT and TT), dehydroepiandrosterone sulphate (DHEAS), and sex hormone-binding globulin (SHBG) were assessed using standardized methods. Health behaviours and medical history were obtained by structured interview. Repeated measures regression was used to describe trends in steroid hormones and SHBG in relation to obesity status, adjusting for age, smoking, alcohol, comorbidities, and physical activity. RESULTS:Obesity was associated with decreased levels of total and free testosterone, and of SHBG at follow-up relative to baseline. For any given baseline concentration of TT, FT or SHBG, follow-up levels were lowest among men who remained obese or who became obese during follow-up. This was true for all three indices of obesity. Central adiposity was associated with lower DHEAS levels at follow-up, while elevated body mass index was not. CONCLUSIONS:Obesity may predict greater decline in testosterone and SHBG levels with age. Central adiposity may be a more important predictor of decline in DHEAS than is body mass index.

    BACKGROUND & AIMS: BACKGROUND:Recent studies of pancreatic cancer suggest a role for hyperinsulinemia in carcinogenesis. Because insulin is secreted in response to elevated blood glucose concentrations, dietary factors that increase these concentrations may be important in pancreatic carcinogenesis. OBJECTIVE:The objective was to examine prospectively the relation between pancreatic cancer risk and dietary glycemic load (GL), overall glycemic index (GI), and intake of total carbohydrates and mono- and disaccharides. DESIGN:The Netherlands Cohort Study consisted of 120,852 men and women who completed a baseline questionnaire in 1986. After 13.3 y of follow-up, 408 pancreatic cancer cases were detected, 66% of which were microscopically confirmed. A validated 150-item food-frequency questionnaire, completed at baseline, was used to calculate carbohydrate and mono- and disaccharide intakes and the GL and GI of the diet. RESULTS:Dietary GL, GI, or intake of carbohydrates and mono- and disaccharides were not associated with pancreatic cancer risk in this cohort. Also, the associations were not modified by sex. Our results did not change after the analysis was restricted to microscopically confirmed pancreatic cancer cases or after individuals who reported a history of diabetes at baseline were excluded from the analyses. CONCLUSIONS:Overall, our findings do not support the hypothesis that GL, GI, or intake of carbohydrates and mono- and disaccharides are positively associated with pancreatic cancer risk. This is in agreement with previous prospective studies that investigated the relation between GL and GI and pancreatic cancer risk.

    BACKGROUND & AIMS: We demonstrated that the prognosis of breast cancer patients who received adjuvant immunochemotherapy with Krestin (PSK) showed a tendency to be better than that of breast cancer patients receiving chemotherapy only. We retrospectively investigated the usefulness of HLA typing for selecting patients to receive adjuvant immuno-chemotherapy with PSK. One hundred and thirty-four patients with operable breast cancer were typed as HLA-A, -B, -C by a lymphocytotoxicity test. Patients without vascular invasion had no adjuvant therapy (NA group). Patients with vascular invasion in the tumor and/or in the metastatic lymph node were randomized into two groups. In group 1 (FEMP only), a combination chemotherapy of 100 mg of 5-fluorouracil (F), 50 mg of cyclophosphamide (E), 2 mg of mitomycin C (M), and 5 mg of predonisolone (P) was orally administered daily for 28 days (one course). In group 2 (FEMP+PSK), FEMP and 3.0 g of PSK were orally administered for 28 days (one course). Two courses a year of these agents were given for five years in both groups. Each group (NA, FEMP, FEMP+PSK) was stratified by the presence of HLA B40 type (B40(+)) or not (B40(-)). Five- and 10-year disease-free survival (DFS) rates (93%, 80%, respectively) of patients with B40(+) seemed to be better than those (83% and 51%) of patients with B40(-). In the NA group, 5- and 10-year DFS were 100% and 71% in patients with B40(+), 92% and 76% in those with B40(-), respectively. In the FEMP group (chemotherapy only), 5- and 10-year DFS of patients with B40(+) were both 84%. These were not statistically significant compared with those (82% and 33%) of patients with B40(-). On the other hand, in the FEMP+PSK group, 5- and 10-year DFS of patients with B40(+) were both 100%, and those of patients with B40(-) were 76% and 55%, respectively. DFS of patients with B40(+) was significantly better than that of patients with B40(-). It is concluded that HLA typing may be a predictive index in determining the use of immunochemotherapy combined with PSK for patients with operable breast cancer.

    背景与目标: 我们证明,接受Krestin (PSK) 辅助免疫化疗的乳腺癌患者的预后显示出比仅接受化疗的乳腺癌患者更好的趋势。我们回顾性研究了HLA分型对选择接受PSK辅助免疫化疗的患者的有用性。通过淋巴细胞毒性试验将134例可手术的乳腺癌患者分为hla-a,-B,-C。无血管侵犯的患者没有辅助治疗 (NA组)。肿瘤和/或转移淋巴结中血管浸润的患者被随机分为两组。在第1组 (仅FEMP) 中,每天口服给药100 mg 5-氟尿嘧啶 (F),50 mg环磷酰胺 (E),2 mg丝裂霉素c (M) 和5 mg泼尼松龙 (P) 的联合化疗,持续28天 (一个疗程)。在第2组 (FEMP + PSK) 中,FEMP和3.0g PSK口服给药28天 (一个疗程)。在两组中,这些代理商每年接受两次课程,为期五年。每组 (NA,FEMP,FEMP PSK) 均通过存在HLA B40型 (B40 ()) 或不存在 (B40(-)) 进行分层。B40(+) 患者的5年和10年无病生存率 (DFS) (分别为93% 、80%) 似乎优于B40(-) 患者的 (83% 和51%)。在NA组中,B40(-) 患者的5年和10年DFS分别100% 和71%,B40(-) 患者的92% 和76%。在FEMP组 (仅化疗) 中,B40(+) 患者的5年和10年DFS均为84%。与B40(-) 患者的 (82% 和33%) 相比,这些没有统计学意义。另一方面,在FEMP PSK组中,B40 () 患者的5年和10年DFS均为100%,B40(-) 患者的5年和10年DFS分别为76% 和55%。B40(+) 患者的DFS显著优于B40(-) 患者。结论HLA分型可能是确定免疫化疗联合PSK用于可手术乳腺癌患者的预测指标。

    BACKGROUND & AIMS: OBJECTIVE:Auriculotherapy is based on the stimulation of reflex points in the ear. However, little is known about its weight-reducing effects. The aim of the present systematic review and meta-analysis was to investigate the effects of auriculotherapy on weight and/or (BMI) reduction in overweight or patients with obesity. METHODS:Twelve articles were selected for systematic review. Four randomized controlled trials (RCTs) investigating weight reduction and five investigating BMI reduction were selected for the meta-analyzes. RESULTS:The results revealed an association between auriculotherapy and weight reduction (WMD, 1.507; 95% CI, 0.606-2.407; p < 0.000). Auriculotherapy was also significantly associated with BMI reduction (WMD, 0.865; 95% CI, 0.533-1.196; p < 0.004). CONCLUSIONS:We found that auriculotherapy was effective in reducing weight and/or BMI in overweight or patients with obesity. However, the findings should be interpreted with caution due to heterogeneity.

    BACKGROUND & AIMS: BACKGROUND:The incidence of heart failure (HF) is decreasing in older ages, but increasing rates have been observed among younger persons in Sweden. Therefore, we investigated the relationship between risk of hospitalization for HF and body mass index (BMI). METHODS:This was a prospective registry-based cohort study. We included 1,374,031 women aged 18-45 years (mean age 27.9 years) who gave birth during 1982-2014, and were registered in the Medical Birth Register. Information on hospitalization because of HF was collected through linkage to the National Inpatient Register. RESULTS:Compared to women with a BMI of 20-<22.5 kg/m2, women with a BMI of 22.5-<25.0 had a hazard ratio (HR) of 1.24 (95% confidence interval (CI), 1.10-1.39) for HF after adjustment for age, year, parity, baseline disorders, smoking, and education. The HR (95% CI) increased to 1.56 (1.36-1.78), 2.39 (2.05-2.78), 2.82 (2.43-3.28), and 4.51 (3.63-5.61) in women with a BMI of 25-<27.5, 27.5-<30, 30-<35, and ≥35 kg/m2, respectively. The multiple-adjusted HRs (95% CI) associated with risk of HF per one-unit increase in BMI in women with a BMI ≥ 22.5 kg/m2 ranged from 1.01 (0.97-1.06) for HF related to valvular disease to 1.14 (1.12-1.15) for coronary heart disease, diabetes, or hypertension. CONCLUSION:Increasing body weight was strongly associated with the risk of early HF in women. Compared with lean women, the risk for HF started to increase at high-normal BMI levels, and was nearly five-fold in women with a BMI ≥ 35 kg/m2.
