Selected AbstractsLifestyle risk factors for intrahepatic stone: Findings from a case,control study in an endemic area, TaiwanJOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 7pt1 2008Masato Momiyama Abstract Background and Aim:, To examine associations between lifestyle risk factors and intrahepatic stone (IHS), we conducted a case,control study in Taiwan, which has the highest incidence of IHS in the world. Methods:, Study subjects were 151 patients newly diagnosed with IHS at Chang Gung Memorial Hospital between January 1999 and December 2001. Two control subjects per case were selected randomly from patients who underwent minor surgery at the same hospital and from family members or neighbors of the hospital staff. Controls were matched to each case by age and gender. Information on lifestyle factors was collected using a self-administered questionnaire. Strength of associations was assessed using odds ratios derived from conditional logistic models. Results:, Female patients were significantly shorter than female controls. Compared to subjects with two or fewer children, odds ratios for those with six or more children were 20.4 in men (95% confidence interval, 1.89,221) and 2.82 (0.97,8.22) in women. Increasing level of education lowered the risk of intrahepatic stone (trend P = 0.004 for men and < 0.0001 for women). Women who had consumed ground-surface water for a long period had a somewhat increased risk (trend P = 0.05). Conclusion:, Lower socioeconomic status and poor hygiene may be involved in the development of intrahepatic stones. [source] Obesity and lifestyle risk factors for gastroesophageal reflux disease, Barrett esophagus and esophageal adenocarcinomaDISEASES OF THE ESOPHAGUS, Issue 5 2006P. J. Veugelers SUMMARY., The aim of this study was to examine the association of obesity with esophageal adenocarcinoma, and with the precursor lesions Barrett esophagus and gastroesophageal reflux disease (GERD). This case-control study included cases with GERD (n = 142), Barrett esophagus (n = 130), and esophageal adenocarcinoma (n = 57). Controls comprised 102 asymptomatic individuals. Using logistic regression methods, we compared obesity rates between cases and controls adjusting for differences in age, gender, and lifestyle risk factors. Relative to normal weight, obese individuals were at increased risk for esophageal adenocarcinoma (Odds Ratio [OR] 4.67, 95% Confidence Interval [CI] 1.27,17.9). Diets high in vitamin C were associated with a lower risk for GERD (OR 0.40, 95% CI 0.19,0.87), Barrett esophagus (OR 0.44, 95% CI 0.20,0.98), and esophageal adenocarcinoma (OR 0.21, 95% CI 0.06,0.77). For the more established risk factors, we confirmed that smoking was a significant risk factor for esophageal adenocarcinoma, and that increased liquor consumption was associated with GERD and Barrett esophagus. In light of the current obesity epidemic, esophageal adenocarcinoma incidence rates are expected to continue to increase. Successful promotion of healthy body weight and diets high in vitamin C may substantially reduce the incidence of this disease. [source] Cervical carcinoma in Algiers, Algeria: Human papillomavirus and lifestyle risk factorsINTERNATIONAL JOURNAL OF CANCER, Issue 3 2005Doudja Hammouda Abstract We conducted a hospital-based case-control study in Algiers, Algeria. A total of 198 cervical carcinoma (CC) cases (including 15 adeno- and adenosquamous carcinomas) and 202 age-matched control women were included. Human papillomavirus (HPV) DNA in cervical cells was evaluated using a PCR assay. Odds ratios and corresponding confidence intervals were computed by means of unconditional multiple logistic regression models. HPV infection was detected in 97.7% of CC cases and 12.4% of control women (OR = 635). Nineteen different HPV types were found. HPV 16 was the most common type in both CC cases and control women, followed by HPV 18 and 45. Twelve types (HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 66 and 73) were found as single infections in CC cases. Multiple HPV infections did not show a higher odds ratio for CC than single infections. In addition to HPV infection, husband's extramarital sexual relationships with other women (OR = 4.8) or prostitutes (OR = 3.2), residing in a rural environment for most of one's life (OR = 4.9) and indicators of poor sanitation or poor hygiene were the strongest risk factors for CC. Oral contraceptive use was unrelated to CC risk, while multiparity emerged as a significant risk factor after adjustment for sexual habits. Intrauterine device users showed a lower CC risk than nonusers. The role of major risk factors, except inside toilet, was confirmed in the analysis restricted to HPV-positive women. The distribution of HPV types in CC cases and control women in Algeria is more similar to the one found in Europe than the one in sub-Saharan Africa, where HPV 16 is less prevalent. A vaccine against HPV 16 and 18 may be effective in more than 3/4 of CCs in Algeria. [source] Evaluation of dietary, medical and lifestyle risk factors for incident kidney cancer in postmenopausal womenINTERNATIONAL JOURNAL OF CANCER, Issue 1 2004Kristin K. Nicodemus Abstract Kidney cancer incidence rates in the United States have been increasing and are not fully accounted for by better diagnostic techniques. Risk factors in women are incompletely described. A total of 34,637 Iowan women initially free of cancer completed a mailed questionnaire in 1986. Kidney cancer incidence was identified over 15 years of follow-up (n = 124) through linkage to a statewide cancer registry. Adjusted for age and other risk factors, kidney cancer was associated positively with maximum adult weight (p for trend = 0.02) and current waist-to-hip ratio (p for trend = 0.002). Compared to nondrinkers, consumers of alcohol of 3.0 or more grams per day had a relative risk (RR) of 0.52 (95% CI = 0.29,0.92). Total vitamin C intake was associated positively with risk of kidney cancer (p for trend = 0.04), whereas total vitamin E intake was associated negatively with risk (p for trend = 0.002). The few women who used copper supplements had a 6.52-fold increase in risk of kidney cancer (95% CI = 1.95,21.8). Compared to never users, women who were former users of estrogen had an increased risk of kidney cancer (RR = 1.62; 95% CI = 1.11,2.36), but current users of estrogen were not at a higher risk. Women who were nulliparous or had more than 2 live births were also at increased risk of kidney cancer compared with women who had 1 or 2 live births. In conclusion, in these postmenopausal women, overweight, particularly central adiposity, was an important risk factor for kidney cancer. Potential risk factors that warrant further exploration were low intake of alcohol and vitamin E, higher intake of vitamin C, nulli- or multiparity and use of copper supplements. © 2003 Wiley-Liss, Inc.

[source] An exploration of mental health nursing students' experiences and attitudes towards using cigarettes to change client's behaviourJOURNAL OF PSYCHIATRIC & MENTAL HEALTH NURSING, Issue 8 2010M. J. NASH msc pclt bsc (hons) rnt rmn fhea Accessible summary ,,This study explores the experiences of mental health nursing students in using cigarettes as a means of token economy. ,,The majority of the sample experienced the use of this particular intervention in various settings but also reported that other items apart from cigarettes were also used as part of a reward system. ,,Respondents generally did not like this practice, feeling that it did not work well, led to client staff conflict, was implemented in an ad hoc way and rarely recorded in a care plan. ,,An open debate on tobacco control and the use of cigarettes in behavioural change programmes is urgently required. Abstract Using cigarettes to change client behaviour is a common, yet little studied, practice in mental health care. A questionnaire survey was used to explore mental health nursing student's experiences and attitudes to this practice. The sample was four cohorts of mental health nursing students (n= 151). Of them, 84% had experienced the practice of using cigarettes to change client behaviour in acute wards (73%), rehabilitation wards (28%) and elderly care (14%). Cigarettes were used to change client behaviour in areas such as attending to personal hygiene (57%) or engaging in the ward routine (39%). However, items such as leave (60%) or drinks (tea and coffee) (38%) were also reportedly used. Of the respondents, 54% inferred that the practice did not work well with 46% stating it was not written up in care plans; 52% felt it was an ad hoc practice, 60% inferred that at times it was used as a punishment while 55% intimated that they felt bad withholding cigarettes. There are ethical and moral dilemmas around using lifestyle risk factors as rewards or using client's nicotine addiction as a means of controlling behaviour. The question of whether this intervention should ever be used, given its associated health risk, requires more critical debate in clinical practice. [source] Autochthonous hepatitis E in southwest EnglandJOURNAL OF VIRAL HEPATITIS, Issue 5 2007H. R. Dalton Summary., Although autochthonous hepatitis E has been reported in developed countries, its extent and nature in the United Kingdom are unclear. The aim of the present study was to report the natural history, lifestyle risk factors and molecular epidemiology of autochthonous hepatitis E infection in southwest England. Three hundred and thirty-three patients with unexplained hepatitis were tested for markers of hepatitis E virus (HEV) infection over a 7-year period. HEV RNA isolated from the cases was amplified and characterized. Of the 333 patients, 21 had autochthonous hepatitis E. Patients were middle-aged or elderly and males were more commonly affected. Clinical manifestations ranged from asymptomatic infection to severe hepatitis. Of the 21 patients, 20 recovered within 6 weeks. None of the cases had travelled to an area endemic for HEV. None of the patients were vegetarian and all ate pork. Of the 21 cases, 20 occurred in the spring, summer and autumn months. All polymerase-chain-reaction-confirmed cases carried HEV genotype 3, which bore close sequence homology to HEV circulating in UK pigs. In the United Kingdom, autochthonous hepatitis E may be more common than previously recognized. Although the mode of transmission remains to be determined, it may be a zoonosis with pigs as a reservoir. Hepatitis E should be considered a public health issue in the United Kingdom. [source] Ergonomic and socioeconomic risk factors for hospital workers' compensation injury claimsAMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 7 2009Jon Boyer ScD Abstract Background Hospital workers are a diverse population with high rates of musculoskeletal disorders (MSDs). The risk of MSD leading to workers' compensation (WC) claims is likely to show a gradient by socioeconomic status (SES) that may be partly explained by working conditions. Methods A single community hospital provided workforce demographics and WC claim records for 2003,2005. An ergonomic job exposure matrix (JEM) was developed for these healthcare jobs from direct observation of physical workload and extraction of physical and psychosocial job requirements from the O*NET online database. Occupational exposures and SES categories were assigned to workers through their O*NET job titles. Univariate and multivariate Poisson regression analyses were performed to estimate the propensity to file an injury claim in relation to individual factors, occupational exposures, and SES. Results The jobs with the highest injury rates were nurses, semi-professionals, and semi-skilled. Increased physical work and psychological demands along with low job tenure were associated with an increase in risk, while risk decreased with psychosocial rewards and supervisor support. Both occupational and individual factors mediated the relationship between SES and rate of injury claims. Conclusions Physical and organizational features of these hospital jobs along with low job tenure predicted WC injury claim risk and explained a substantial proportion of the effects of SES. Further studies that include lifestyle risk factors and control for prior injuries and co-morbidities are warranted to strengthen the current study findings. Am. J. Ind.

Robinson PhD Abstract Background Studies of truck drivers and cardiovascular disease (CVD), myocardial infarction, or ischemic heart disease (IHD) are limited, although studies of other professional drivers reported increased risk. Methods US mortality data from 1979 to 1990 for ages 15,90 were used to calculate proportional mortality ratios (PMRs) for heart disease and lung cancer for short and long haul truck drivers. Analysis was performed for Black (998 short haul and 13,241 long haul) truck drivers and White (4,929 short and 74,315 long haul) truck drivers separately. Results The highest significantly elevated proportionate heart disease (IHD, acute myocardial infarction (AMI), and other forms of heart disease) and lung cancer mortality was found for White and Black male long haul truck drivers age 15,54. Mortality was not significantly elevated for short haul truck drivers of either race or gender, nor for truck drivers who died after age 65, except for lung cancer among White males. An indirect adjustment suggested that smoking could explain the excess IHD mortality, but no direct data for smoking or the other known risk factors for heart disease were available and occupational exposures were not measured. Conclusions The highest significant excess proportionate mortality for lung cancer, IHD and AMI was found for long haul truck drivers who were under age 55 at death. A cohort or longitudinal study of heart disease among long haul truck drivers, that obtains data for occupational exposures as well as lifestyle risk factors, could help explain inconsistencies between the findings of this and previous studies.

[source] Modelling the impact of modifying lifestyle risk factors on dementia prevalence in Australian population aged 45 years and over, 2006,2051AUSTRALASIAN JOURNAL ON AGEING, Issue 3 2010Binod Nepal Aim:, To model impact of modifiable risk behaviour on dementia prevalence among the Australian population aged 45 years and over. Methods:, A group-based computer model was constructed to estimate the impact of modifying risk behaviour on dementia prevalence. Results:, Based on population ageing, the number of people aged 45 years and over living with dementia is expected to triple from 187 000 in 2006 to 650 000 by 2051. A drop in proportion ever smokers by 5% every 5 years would lower population with dementia by 2% in 2051. If obesity rate drops by 5%, dementia prevalence would be lower by 6%. A decline in physical inactivity rate by 5% would reduce dementia by 11%. Persistence of the growing trend in obesity and physical inactivity would result in a larger than expected dementia epidemic. Conclusion:, Improving the risk behaviours has potential to make a substantial reduction in the number of people with dementia. [source] Preventing Fractures in Large Rural Centres: Sociodemographic Sub-Groups at Risk of Osteoporosis from their LifestyleAUSTRALIAN JOURNAL OF RURAL HEALTH, Issue 6 2000Hedley G. Peach ABSTRACT Middle-aged people living in non-metropolitan Victoria have higher hospitalisation rates from osteoporotic fractures than those in metropolitan areas. This may reflect a higher prevalence of lifestyle risk factors for osteoporosis. One-fifth of Victoria's non-metropolitan population live in ,large rural centres'. The aim of the present study was to identify the sociodemographic sub-groups in a ,large rural centre' at risk of osteoporosis because of their lifestyle. Adults on Ballarat's electoral rolls were invited to complete a questionnaire and have their height and weight measured. A total of 335 eligible people participated in the present study (67% response). The sub-groups at risk of osteoporosis were identified using logistic regression analyses. Among women, being single/separated/divorced/ widowed was associated with being underweight and having low dietary calcium. A lack of exercise was associated with not completing high school and smoking with being aged 25,44 years. Among men, low dietary calcium was associated with not completing high school and smoking was associated with being employed in a non-professional/ non-managerial occupation. These sub-groups must be considered when planning preventative strategies for people in ,large rural centres'.
