PURPOSE: Several studies reported a difference in herpes zoster (HZ) incidence between males and females, but limitations in design and analysis impeded the assessment of gender as an independent risk factor for HZ. This study examines the independent etiologic association between gender and HZ. METHODS: A total of 335,714 persons were observed prospectively during 2001. We registered gender and HZ occurrence, as well as other risk factors for HZ. We calculated overall crude and adjusted odds ratios (ORs) and stratified to age. RESULTS: The HZ incidence in females was 3.9/1000 patients/year (95% confidence interval [CI], 3.6-4.2), and in males, 2.5/1000 patients/year (95% CI, 2.3-2.8), with a crude OR of 1.53 (95% CI, 1.36-1.74). After adjustment for potential confounders, the adjusted OR was 1.38 (95% CI, 1.22-1.56). The incidence was greater in females in the middle-aged (age, 25 to 64 years; OR range, 1.36 to 1.83) and youngest group (OR, 1.31; 95% CI, 0.90-1.89). Gender effect was inverse in young adults (age, 15 to 24 years; OR, 0.64; 95% CI, 0.41-1.03). CONCLUSION: Female gender is an independent risk factor for HZ in the 25- to 64-year-old age groups.  相似文献

OBJECTIVE We wanted to determine the incidence of hypertension and its risk factors among rural Chinese adults.METHODS A population-based sample of 24,360 rural Chinese adults aged 35 years and older and free from hypertension at baseline was observed from 2004–2006 to 2008. Incident hypertension was defined as a systolic pressure of 140 mm Hg or greater, diastolic pressure of 90 mm Hg or greater, or current use of antihypertensive medication.RESULTS During a mean follow-up period of 28 months, 29.6% of men and 23.4% of women developed hypertension. The age-adjusted incidence was higher in men (12.75 per 100 person-years) than in women (10.04 per 100 person-years). Among men, independent predictors of incident hypertension were baseline age (hazard ratio [HR] = 1.11; 95% confidence interval [CI], 1.10–1.13), Mongolian ethnicity (HR = 1.09; 95% CI, 1.01–1.18), use of alcohol, (HR = 1.14; 95% CI, 1.06–1.23), high income vs low income (HR = 1.11; 95% CI, 1.00–1.22; and HR = 1.11; 95% CI, 1.03–1.20), prehypertension vs normotension (HR = 1.18; 95% CI, 1.08–1.28), overweight and obesity (HR = 1.28; 95% CI, 1.17–1.40), baseline salt intake (HR = 1.00; 95% CI, 1.00–1.01) and family history of hypertension (HR = 1.14; 95% CI, 1.03–1.27). With the exception of use of alcohol and mean income, the results were similar for women, except that low physical activity was shown as a risk factors as well. The awareness, treatment, and control rates for newly developed hypertension were 29.9%, 19.5%, and 1.5%, respectively.CONCLUSIONS These data indicate that the incidence of hypertension is high among these rural Chinese adults and that it is associated with many risk factors. Our findings further suggest that most newly developed hypertension cases are not treated. The increases in hypertension are probably related to rapid social changes in our country and may apply to other areas of the developing world. These findings call for urgent improvements in hypertension prevention and control programs in rural China.  相似文献

BACKGROUND: Figures on GP-diagnosed respiratory tract infections (RTI) are outdated because of demographic changes and increase in co-morbid conditions, respiratory vaccination programmes and change in illness behaviour. OBJECTIVE: To determine the incidence of RTI in patients presenting to the GP according to age, gender and common high-risk co-morbidity in primary care. METHODS: In the Second Dutch National Survey of General Practice 90 computerized general practices with 358,008 patients recorded all consecutive patient contact by use of the ICPC coding system in a year. Incidences were calculated using the mid-year population in the denominator and RTI episodes as the nominator. RESULTS: In all, 4.2% of the patient population were diagnosed with RTI with an incidence rate of 144 per 1000 person-years. Upper RTI were more common in children of 0-4 years than in other year-cohorts [392 versus 80 per 1000; relative risk 4.9, 95% confidence interval (95% CI) 4.8-5.0]. An U-shape association was observed between age and lower RTI (78 and 70 per 1000 in children and persons aged 75 years or over, respectively, versus 23 per 1000 in other age-categories). Females had slightly higher incidence rates of URTI (relative risk 1.4, 95% CI 1.35-1.45) and similar rates for LRTI. Patients with chronic medical conditions as pulmonary and cardiac disease, and diabetes. DISCUSSION: A small proportion of the patient population present themselves to the GP with a RTI. RTI are more common among children, elderly persons and patients with pulmonary and cardiac disease, and diabetes of the ICPC coding system.  相似文献

The authors characterized human immunodeficiency virus (HIV) and hepatitis C virus (HCV) incidence and prospective changes in self-reported risk behavior over 2 years among 1,158 injection drug users (IDUs) recruited in Chennai, India, in 2005-2006. At baseline, HIV prevalence was 25.3%, and HCV prevalence was 54.5%. Seropositive persons with prevalent HIV infection were used to estimate baseline HIV incidence by means of the Calypte HIV-1 BED Incidence EIA (Calypte Biomedical Corporation, Portland, Oregon). Longitudinal HIV and HCV incidence were measured among 865 HIV-negative IDUs and 519 HCV antibody-negative IDUs followed semiannually for 2 years. Participants received pre- and posttest risk reduction counseling at each visit. Estimated HIV incidence at baseline was 2.95 per 100 person-years (95% confidence interval (CI): 1.21, 4.69) by BED assay; observed HIV incidence over 1,262 person-years was 0.48 per 100 person-years (95% CI: 0.17, 1.03). HCV incidence over 645 person-years was 1.71 per 100 person-years (95% CI: 0.85, 3.03). Self-reported risk behaviors declined significantly over time, from 100% of participants reporting drug injection at baseline to 11% at 24 months. In this cohort with high HIV and HCV prevalence at enrollment, the authors observed low incidence and declining self-reported risk behavior over time. While no formal intervention was administered, these findings highlight the potential impact of voluntary counseling and testing in a high-risk cohort.  相似文献

BACKGROUND: There have been few long-term population-based studies of viral meningitis, and only a limited number of potential risk factors have been evaluated. METHODS: We estimated the incidence of viral meningitis hospitalization in childhood, and assessed risk factors for this disease through a population-based cohort study comprising all children born in Denmark from 1977 through 2001 (n = 1.5 million). Information on sex, number of children and adults in the household, age of parents at child's birth, degree of urbanization, birth weight, gestational age, and possible complications at birth were linked to the children in the cohort, together with information on hospitalization with viral meningitis. We calculated incidence rates of viral meningitis and estimated rate ratios according to the various risk factors using Poisson regression. RESULTS: The incidence rate was highest in the first 6 months of life (38.7 per 100,000 person-years), with a peak right after birth (58.7 per 100,000 person-years). A secondary peak was seen among 5-year-old children (15.6 per 100,000 person-years). Overall incidence rates decreased throughout the study period, with outbreaks occurring every 3 to 5 years [decrease in rate ratio per calendar year = 0.95; 95% confidence interval (CI) = 0.94-0.96]. Summer and early fall peaks were present. We observed independent effects of sex (girls vs. boys: rate ratio = 0.47 [95% CI = 0.43-0.53]), children in the household (eg, living with 3+ younger children vs. living with none: 1.94 [1.22-3.07]), single parenthood (living with 1 parent vs. living with 2 parents: 1.30 [1.12-1.39]), degree of urbanization (children living in the capital vs. children living in small town and rural areas: 1.54 [1.31-1.80]), low birth weight (increase in RR per 500 g reduction in birth weight = 1.05 [1.00-1.09]), prematurity (increase in RR per 1 week reduction in gestational age = 1.03 [1.01-1.04]), and cesarean section (cesarean section vs. vaginal birth: 1.29 [1.12-1.49]). CONCLUSIONS: Incidence of viral meningitis hospitalization is highest immediately after birth with a secondary peak at age 5. Lack of passive maternally acquired antibodies and preferential hospitalization are the likely causes for the peak in infancy. Increased transmission in kindergarten, preschool, and day care could explain the secondary peak. The incidence decreased throughout the 25-year study period perhaps due to improved public hygiene. Among the assessed risk factors, we found the strongest to be male sex, a high number of children in the household, and degree of urbanization.  相似文献

ObjectiveTo evaluate the incidence of hip fracture in patients with antipsychotic treatment, comparing it with that of individuals who have not been treated with antipsychotics.DesignRetrospective cohort study of patients treated with antipsychotic drugs (TAP) and patients without known treatment (non-TAP). The observation period was 2006–2014.SiteAll primary care teams in Catalonia of the Catalan Health Institute (ICS).ParticipantsPatients older than 44 years with TAP lasting at least 3 months. Control cohort: random selection of non-TAP patients matching for baseline comorbidities and other variables. A total of 22,010 are analyzed.Main measurements Incidence rate (1000× person-years: PY) of hip fracture in each group (TAP and non-TAP). Cox regression models to estimate adjusted risks (hazard ratio: HR).ResultsThe hip fracture incidence rate was higher in TAP patients (5.83 vs 3.58 fractures per 1000 PY), and is higher in all strata according to sex, age and type of diagnosis. The risk of suffering a hip fracture was 60% higher (HR: 1.60 95% CI: 1.34–1.92) in the TAP group than in the non-TAP group. The risk was higher in the group with schizophrenia (HR: 3.57 95% CI: 1.75–7.30), followed by bipolar disorder (HR: 2.61; 95% CI: 1.39–4.92) and depression (HR: 1.51; 95% CI: 1.21–1.88).ConclusionsPatients with antipsychotic treatment have a higher risk of hip fracture than those who have not been treated with antipsychotics.  相似文献

OBJECTIVES: This study estimated the risk of incident stroke according to the level of job control and examined whether the association between job control and the risk of stroke varied as a function of gender. METHODS: This was a register-based cohort study of nearly 3 million working people (age 30-64 years in 1990) with a 13-year follow-up (1991-2003) for incident stroke (50 114 events). Job control was aggregated to the data by a secondary data source (job-exposure matrix) in 1990. Gender-specific Cox regressions were applied. RESULTS: The age- and workhour-adjusted hazard ratio of the lowest versus the highest job control quartile was 1.25 [95% confidence interval (95% CI) 1.17-1.32] for any stroke, 1.33 (95% CI 1.15-1.55) for intracerebral hemorrhage, and 1.22 (95% CI 1.14-1.31) for brain infarction among the women, and the corresponding figures for the men were 1.24 (95% CI 1.21-1.28), 1.30 (95% CI 1.21-1.40), 1.23 (95% CI 1.19-1.28), respectively. Adjustment for education, marital status, and income attenuated these associations to 1.07 (95% CI 1.01-1.14) for any stroke, 1.22 (95% CI 1.04-1.42) for intracerebral hemorrhage, and 1.04 (95% CI 0.97-1.12) for brain infarction for the women and to 1.08 (95% CI 1.04-1.12), 1.12 (95% CI 1.03-1.22), 1.08 (95% CI 1.04-1.13), respectively, for the men. CONCLUSIONS: The relative risk of stroke was higher in low job-control occupations. The association between job control and stroke subtypes varied as a function of gender. The relative risk of intracerebral hemorrhage was highest for the women in low job-control occupations.  相似文献

The relation between herpes simplex virus type 2 (HSV-2) and human immunodeficiency virus (HIV) acquisition was evaluated among 4,295 high-risk, HIV-negative men who have sex with men in an intensive behavioral intervention (colloquially referred to as "EXPLORE") study in the United States from 1999 to 2003. Sexual behavior data were obtained by computer-assisted self-interview, and sera were collected semiannually for HIV and HSV-2 serology. HSV-2 infection was classified as "recent incident" (at the first HSV-2 seropositive visit), "remote incident" (within 24 months of the first positive visit), and "prevalent" (for visits >24 months after the first HSV-2 positive visit). Baseline HSV-2 prevalence was 20.3%. HSV-2 incidence was 1.9 (95% confidence interval (CI): 1.6, 2.2) per 100 person-years; significant risk factors were African-American race, unprotected receptive anal intercourse, an HIV-positive male sex partner, and six or more male partners in the prior 6 months. The behavioral intervention did not reduce HSV-2 acquisition (adjusted hazard ratio (HR) = 1.2, 95% CI: 0.9, 1.6). Overall HIV incidence was 1.9 (95% CI: 1.7, 2.2) per 100 person-years. HIV risk was elevated among men who have sex with men with recent incident HSV-2 (adjusted HR = 3.6, 95% CI: 1.7, 7.8), remote incident HSV-2 (adjusted HR = 1.7, 95% CI: 0.8, 3.3), and prevalent HSV-2 (adjusted HR = 1.5, 95% CI: 1.1, 2.1) infection compared with HSV-2 seronegative participants. HIV intervention strategies targeting HSV-2 prevention and suppression among men who have sex with men should be evaluated.  相似文献

Background

The relative and absolute risks of stroke and heart failure attributable to atrial fibrillation (AF) have not been sufficiently examined.

Methods

A prospective study of 23,731 community-dwelling Japanese individuals was conducted. Participants were divided into two groups based on the presence or absence of prevalent AF (n = 338 and n = 23,393, respectively). Excess events (EE) due to AF and relative risks (RRs) determined using the non-AF group as the reference for incident stroke and heart failure were estimated using Poisson regression stratified by age groups (middle-aged: 40–69 years old; elderly: 70 years of age or older) after adjustment for sex and age.

Results

There were 611 cases of stroke and 98 cases of heart failure during the observation period (131,088 person-years). AF contributed to a higher risk of stroke both in middle-aged individuals (EE 10.4 per 1000 person-years; RR 4.88; 95% confidence interval [CI], 2.88–8.29) and elderly individuals (EE 18.3 per 1000 person-years; RR 3.05; 95% CI, 2.05–4.54). AF also contributed to a higher risk of heart failure in middle-aged individuals (EE 3.7 per 1000 person-years; RR 8.18; 95% CI, 2.41–27.8) and elderly individuals (EE 15.4 per 1000 person-years; RR 7.82; 95% CI, 4.11–14.9). Results obtained from multivariate-adjusted analysis were similar (stroke: EE 8.9 per 1000 person-years; RR 4.40; 95% CI, 2.57–7.55 in middle-aged and EE 17.4 per 1000 person-years; RR 2.97; 95% CI, 1.99–4.43 in elderly individuals; heart failure: EE 3.1 per 1000 person-years; RR 7.22; 95% CI, 2.06–25.3 in middle-aged and EE 14.1 per 1000 person-years; RR 7.41; 95% CI, 3.86–14.2 in elderly individuals).

Conclusions

AF increased the risk of stroke by the same magnitude as that reported previously in Western countries. AF increased the RR of heart failure more than that in Western populations.  相似文献

Recurrence and second primary cancer (SPC) continue to represent major obstacles to long-term survival in head and neck cancer (HNC). Our aim was to evaluate whether established demographics, lifestyle-related risk factors for HNC and clinical data are associated with recurrence and SPC in HNC. We conducted a multicentre study by using data from five studies members of the International Head and Neck Cancer Epidemiology consortium—Milan, Rome, Western Europe, Sao Paulo, and Japan, totalling 4005 HNC cases with a median age of 59 (interquartile range 52–67). Multivariate hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated for recurrence and SPC. During follow-up, 1161 (29%) patients had recurrence and 343 (8.6%) developed SPC. Advanced tumour stage was associated with increased risk of recurrence in HNC overall (HR?=?1.76, 95% CI 1.41–2.19). Women with laryngeal cancer had a reduced risk of recurrence compared to men (HR?=?0.39, 95% CI: 0.24–0.74). Concerning predictors of SPC, advanced age (HR?=?1.02; 95% CI: 1.00–1.04) and alcohol consumption (>?1 drink per day, HR?=?2.11; 95% CI: 1.13–3.94) increased the risk of SPC among patients with laryngeal cancer. Additionally, women were at higher risk of SPC, in HNC overall group (HR?=?1.68; 95% CI: 1.13–2.51) and oropharyngeal cancer group (HR?=?1.74; 95% CI: 1.02–2.98). Tumour stage and male gender (larynx only) were positive predictors of cancer recurrence in HNC patients. Predictors of SPC were advanced age and alcohol use among laryngeal cancer cases, and female gender for oropharyngeal and HNC overall.  相似文献

This prospective study evaluated regular physical activity and self-reported physician-diagnosed osteoarthritis of the knee and/or hip joints among 16,961 people, ages 20-87, examined at the Cooper Clinic between 1970 and 1995. Among those aged 50 years and older, osteoarthritis incidence was higher among women (7.0 per 1000 person-years) than among men (4.9 per 1000 person-years, P = 0.001), while among those under 50 years of age, osteoarthritis incidence was similar between men (2.6) and women (2.7). High levels of physical activity (running 20 or more miles per week) were associated with osteoarthritis among men under age 50 after controlling for body mass index, smoking, and use of alcohol or caffeine (hazard ratio = 2.4, 95% CI: 1.5, 3.9), while no relationship was suggested among women or older men. These findings support the conclusion that high levels of physical activity may be a risk factor for symptomatic osteoarthritis among men under age 50.  相似文献

The authors investigated the cancer risk of patients hospitalized for depression in a nationwide Danish cohort study. All 89,491 adults in Denmark who had been admitted to a hospital with depression, as defined in the International Classification of Diseases, Eighth Revision, between 1969 and 1993 were identified. There were 1,117,006 person-years of follow-up. Incidence rates of all cancers and of site-specific cancers were compared with national incidence rates for first primary cancers, with data being adjusted for sex, age, and calendar time. A total of 9,922 cases of cancer were diagnosed in the cohort, with 9,434.6 having been expected; this yielded a standardized incidence ratio of 1.05 (95% confidence interval (CI): 1.03, 1.07). The risk of cancer was increased for the first year after hospital admission, with brain cancer especially occurring more frequently than expected. When the first year of follow-up was excluded, the increase was attributable mainly to an increased risk of tobacco-related cancers: Standardized incidence ratios for non-tobacco-related cancers were 1.00 (95% CI: 0.97, 1.03) after 1-9 years of follow-up and 0.99 (95% CI: 0.95, 1.02) after 10 or more years of follow-up. These data provide no support for the hypothesis that depression independently increases risk of cancer, but they emphasize the deleterious effect that depression can have on lifestyle factors.  相似文献

The goal of this study was to estimate the incidence of Parkinson's disease by age, gender, and ethnicity. Newly diagnosed Parkinson's disease cases in 1994-1995 were identified among members of the Kaiser Permanente Medical Care Program of Northern California, a large health maintenance organization. Each case met modified standardized criteria/Hughes diagnostic criteria as applied by a movement disorder specialist. Incidence rates per 100,000 person-years were calculated using the Kaiser Permanente membership information as the denominator and adjusted for age and/or gender using the direct method of standardization. A total of 588 newly diagnosed (incident) cases of Parkinson's disease were identified, which gave an overall annualized age- and gender-adjusted incidence rate of 13.4 per 100,000 (95% confidence interval (CI): 11.4, 15.5). The incidence rapidly increased over the age of 60 years, with only 4% of the cases being under the age of 50 years. The rate for men (19.0 per 100,000, 95% CI: 16.1, 21.8) was 91% higher than that for women (9.9 per 100,000, 95% CI: 7.6, 12.2). The age- and gender-adjusted rate per 100,000 was highest among Hispanics (16.6, 95% CI: 12.0, 21.3), followed by non-Hispanic Whites (13.6, 95% CI: 11.5, 15.7), Asians (11.3, 95% CI: 7.2, 15.3), and Blacks (10.2, 95% CI: 6.4, 14.0).

The current study describes the age- and sex-specific incidence rates and risk factors for asymptomatic and symptomatic peripheral arterial occlusive disease (PAOD) among 2,327 subjects and the incidence of intermittent claudication in asymptomatic PAOD subjects. The study population was selected from 18 general practice centers in the Netherlands. PAOD was assessed with the ankle-brachial blood pressure index, and intermittent claudication was assessed with a modified version of the Rose questionnaire. After 7.2 years, the overall incidence rate for asymptomatic PAOD, using the person-years method, was 9.9 (95% confidence interval (CI): 7.3, 18.8) per 1,000 person-years at risk. The rate was 7.8 (95% CI: 4.9, 20.3) for men and 12.4 (95% CI: 7.7, 24.8) for women. For symptomatic PAOD, the incidence rate was 1.0 (95% CI: 0.7, 7.5) overall, 0.4 (95% CI: 0.3, 10.0) for men, and 1.8 (95% CI: 1.0, 10.3) for women. Multivariate analyses showed that increasing age, smoking, hypertension, and diabetes mellitus were the most important risk factors. The overall incidence rate for intermittent claudication among PAOD subjects who were asymptomatic at baseline was 90.5 per 1,000 person-years at risk (95% CI: 36.4, 378.3). The incidence of asymptomatic PAOD was higher than the incidence of symptomatic PAOD, with women developing PAOD more often than men. In the development of preventive strategies, modification of atherosclerotic risk factors, such as smoking, hypertension, and diabetes, should be the main goals.  相似文献

BACKGROUND: The independent influence of childhood social circumstances on health in later life remains uncertain. We examined the extent to which childhood socio-economic circumstances are related to the risk of coronary heart disease (CHD) in older British men, taking account of adult social class and behavioural risk factors. METHODS: A socio-economically representative sample of 5552 British men (52-74 years) with retrospective assessment of childhood socio-economic circumstances (father's occupation and childhood household amenities) who were followed up for CHD (fatal and non-fatal) for 12 years. RESULTS: Men whose childhood social class was manual had an increased hazard ratio (HR) 1.34 (95% CI 1.11-1.63)-this effect was diminished when adjusted for adult social class and adult behavioural risk factors (cigarette smoking, alcohol, physical activity and body weight) (HR 1.19; 95% CI 0.97-1.46). Men whose family did not own a car in their childhood were at increased CHD risk even after adjustments for adult social class and behaviours (HR 1.35, 95% CI 1.04-1.75). Men with combined exposure to both childhood and adult manual social class had the highest risk of CHD (HR 1.51; 95% CI 1.19-1.91); this was substantially reduced by adjustment for adult behavioural risk factors (adjusted HR 1.28; 95% CI 0.99-1.65). CONCLUSIONS: Less affluent socio-economic conditions in childhood may have a modest persisting influence on risk of CHD in later life.  相似文献

Purpose

Considering the high prevalence of heart failure and the economic burden of the disease, factors that influence in‐hospital mortality are of importance in improving outcomes of care for this patient population. The purpose of this study was to examine the determinants of in‐hospital mortality for adult heart failure patients.

Methods

The study design is a retrospective observational study design using the 2010 Nebraska Hospital Discharge data set including 4,319 hospitalizations for 3,521 heart failure patients admitted to 79 hospitals in Nebraska. Hierarchical logistic regression models including patient‐ and hospital‐specific random intercepts were analyzed. Covariates included in the analysis were patient age in years, gender, comorbidity status, length of stay, primary payer, type and source of admission, transfers, and rurality of county of residence.

Results

Overall, 3.5% of heart failure patients died during their hospital stay. In logistic regression analysis that adjusted for age, sex, and comorbidities, the odds of dying in hospital for heart failure patients increased with age (OR = 1.03, 95% CI: 1.01‐1.04), co‐morbidity (OR = 1.15; 95% CI: 1.05‐1.25) and length of stay (OR = 1.03, 95% CI: 1.01‐1.05). The patient's gender, payer source, rurality of county of residence, source, and type of admission were not risk factors for in‐hospital death.

Conclusion

Increasing age, comorbidity and length of stay were risk factors for in‐hospital death for heart failure. An understanding of the risk factors for in‐hospital death is critical to improving outcomes of care for heart failure patients.  相似文献
