Effectiveness of health checks conducted by nurses in primary care: final results of the OXCHECK study. Imperial Cancer Research Fund OXCHECK Study Group.

OBJECTIVE--To determine the effectiveness of health checks, performed by nurses in primary care, in reducing risk factors for cardiovascular disease and cancer. DESIGN--Randomised controlled trial. SETTING--Five urban general practices in Bedfordshire. SUBJECTS--2205 men and women who were randomly allocated a first health check in 1989-90 and a re-examination in 1992-3 (the intervention group); 1916 men and women who were randomly allocated an initial health check in 1992-3 (the control group). All subjects were aged 35-64 at recruitment in 1989. MAIN OUTCOME MEASURES--Serum total cholesterol concentration, blood pressure, body mass index, and smoking prevalence (with biochemical validation of cessation); self reported dietary, exercise, and alcohol habits. RESULTS--Mean serum total cholesterol was 3.1% lower in the intervention group than controls (difference 0.19 mmol/l (95% confidence interval 0.12 to 0.26)); in women it was 4.5% lower (P < 0.0001) and in men 1.6% (P < 0.05), a significant difference between the sexes (P < 0.01). Self reported saturated fat intake was also significantly lower in the intervention group. Systolic and diastolic blood pressures and body mass index were respectively 1.9%, 1.9%, and 1.4% lower in the intervention group (P < 0.005 in all cases). There was a 3.9% (2.4 to 5.3) difference in the percentage of subjects with a cholesterol concentration > or = 8 mmol/l, but no significant differences in the number with diastolic blood pressure > or = 100 mm Hg or body mass index > or = 30 kg/m2. There was no significant difference between the two groups in prevalence of smoking or excessive alcohol use. Annual rechecks were no more effective than a single recheck at three years, but health checks led to a significant increase in visits to the nurse according to patients'' degree of cardiovascular risk. CONCLUSIONS--The benefits of health checks were sustained over three years. The main effects were to promote dietary change and reduce cholesterol concentrations; small differences in blood pressure may have been attributable to accommodation to measurement. The benefits of systematic health promotion in primary care are real, but must be weighed against the costs in relation to other priorities.     

Reduction in the concentration and activity of plasma cholesteryl ester transfer protein by alcohol.

Plasma cholesteryl esters, synthesized within high density lipoproteins (HDL), may be transferred from HDL particles to other lipoproteins by plasma cholesteryl ester transfer protein (CETP). Alcohol consumption is associated with increased HDL cholesterol concentration and reduced plasma CETP activity. The alcohol-induced decrease in CETP activity may be due to a low concentration of CETP in plasma or the inhibition of CETP by specific inhibitor proteins or alterations in the composition of plasma lipoproteins. The first two possibilities are studied further in this paper using data on 47 alcohol abusers and 31 control subjects. The activity of CETP was measured as the rate of cholesteryl ester transfer between radio-labeled low density lipoproteins and unlabeled HDL using an in vitro method independent of endogenous plasma lipoproteins. Plasma CETP concentration was determined by a Triton-based radioimmunoassay. The alcohol abusers consuming alcohol (on average 154 g/day) had 28% higher HDL cholesterol (P less than 0.01), 27% lower plasma CETP concentration (P less than 0.001), and 22% lower plasma CETP activity (P less than 0.001) than the controls. Plasma CETP concentration showed a negative correlation with HDL cholesterol among all the subjects (r = -0.317, P less than 0.01) but not among the alcohol abusers alone (r = -0.102, N. S.). During 2 weeks of alcohol withdrawal, plasma CETP concentration and activity of 8 subjects increased, whereas HDL cholesterol decreased by 42% (P less than 0.02).(ABSTRACT TRUNCATED AT 250 WORDS)     

Effectiveness of health checks conducted by nurses in primary care: results of the OXCHECK study after one year. Imperial Cancer Research Fund OXCHECK Study Group.

OBJECTIVE--To assess the effectiveness of health checks by nurses in reducing risk factors for cardiovascular disease in patients from general practice. DESIGN--Randomised controlled trial. SETTING--Five urban general practices in Bedfordshire. SUBJECTS--2136 patients receiving an initial health check in 1989-91 and scheduled to be re-examined one year later in 1990-2 (intervention group); 3988 patients receiving an initial health check in 1990-2 (control group). All patients were aged 35-64 years at recruitment in 1989. MAIN OUTCOME MEASURES--Serum total cholesterol concentration, blood pressure, body mass index, confirmed smoking cessation. RESULTS--Mean serum total cholesterol was 2.3% lower in the intervention group than in the controls (difference 0.14 mmol/l (95% confidence interval 0.08 to 0.20)); the difference was greater in women (3.2%, P < 0.0001) than men (1.0%, P = 0.18). There was no significant difference in smoking prevalence, quit rates, or body mass index. Systolic and diastolic blood pressure were 2.5% and 2.4% lower respectively in the intervention group. The proportion of patients with diastolic blood pressure > or = 100 mm Hg was 2.6% (55/2131) in the intervention group and 3.4% (137/3987) in the controls (difference 0.9% (0.0 to 1.7)); the proportion with total cholesterol concentration > or = 8 mmol/l 4.8% (100/2068) and 7.6% (295/3905) (difference 2.7% (1.5 to 4.0)); and that with body mass index > or = 30 12.4% (264/2125) and 14.0% (559/3984) (difference 1.6% (-0.2 to 3.4)). CONCLUSIONS--General health checks by nurses are ineffective in helping smokers to stop smoking, but they help patients to modify their diet and total cholesterol concentration. The public health importance of this dietary change depends on whether it is sustained.     

Randomised controlled trial evaluating cardiovascular screening and intervention in general practice: principal results of British family heart study. Family Heart Study Group.

OBJECTIVE--To measure the change in cardiovascular risk factors achievable in families over one year by a cardiovascular screening and lifestyle intervention in general practice. DESIGN--Randomised controlled trial in 26 general practices in 13 towns in Britain. SUBJECTS--12,472 men aged 40-59 and their partners (7460 men and 5012 women) identified by household. INTERVENTION--Nurse led programme using a family centred approach with follow up according to degree of risk. MAIN OUTCOME MEASURES--After one year the pairs of practices were compared for differences in (a) total coronary (Dundee) risk score and (b) cigarette smoking, weight, blood pressure, and random blood cholesterol and glucose concentrations. RESULTS--In men the overall reduction in coronary risk score was 16% (95% confidence interval 11% to 21%) in the intervention practices at one year. This was partitioned between systolic pressure (7%), smoking (5%), and cholesterol concentration (4%). The reduction for women was similar. For both sexes reported cigarette smoking at one year was lower by about 4%, systolic pressure by 7 mm Hg, diastolic pressure by 3 mm Hg, weight by 1 kg, and cholesterol concentration by 0.1 mmol/l, but there was no shift in glucose concentration. Weight, blood pressure, and cholesterol concentration showed the greatest difference at the top of the distribution. If maintained long term the differences in risk factors achieved would mean only a 12% reduction in risk of coronary events. CONCLUSIONS--As most general practices are not using such an intensive programme the changes in coronary risk factors achieved by the voluntary health promotion package for primary care are likely to be even smaller. The government''s screening policy cannot be justified by these results.     

Insulin sensitivity and regular alcohol consumption: large,prospective, cross sectional population study (Bruneck study)

OBJECTIVES: To assess the relation between regular alcohol consumption and insulin sensitivity, and to estimate the importance of insulin in the association of alcohol with multiple vascular risk factors and cardiovascular disease. DESIGN: Prospective and cross sectional study of a large randomly selected population sample. SETTING: Part of the Bruneck study 1990-5 (Bolzano province, Italy). SUBJECTS: 820 health, non-diabetic women and men aged 40-79 years. MAIN OUTCOME MEASURE: Concentrations of fasting and post-glucose insulin, cholesterol, apolipoproteins, triglycerides, Lp(a) lipoprotein glucose, fibrinogen, and antithrombin III; blood pressure; insulin resistance estimated by the homeostasis model assessment. RESULTS: Fasting insulin concentrations in those who did not drink alcohol and subjects reporting low (1-50 g/day), moderate (51-99 g/day), and heavy (> or = 100 g/day) alcohol intake were 12.4, 10.0, 8.7, and 7.1 mU/l (P < 0.001). Likewise, post-glucose insulin concentrations and estimates for insulin resistance assessed by the homeostasis model assessment decreased significantly with increasing amounts of regular alcohol consumption. These trends were independent of sex, body mass index, physical activity, cigarette smoking, medication, and diet (P < 0.001). Regular alcohol intake predicted multiple changes in vascular risk factors over a five year period including increased concentrations of high density lipoprotein cholesterol and apolipoprotein A I; higher blood pressure; and decreased concentration of antithrombin III. These associations were in part attributable to the decrease in insulin concentrations observed among alcohol consumers. CONCLUSIONS: Low to moderate amounts of alcohol, when taken on a regular basis, improve insulin sensitivity. Insulin is a potential intermediate component in the association between alcohol consumption and vascular risk factors (metabolic syndrome).     

The Dundee coronary risk-disk for management of change in risk factors.

OBJECTIVE--To devise a simplified system for grading and monitoring modifiable coronary risk in primary care, to be used with an action plan. METHODS--The risk equation came from 5203 men aged 40-59 in the United Kingdom heart disease prevention project, who had 331 coronary events over five years; the population rank (reading 1-100) was obtained by scoring 10,359 participants in the Scottish heart health study. Calculation of rank was embodied in the Dundee coronary risk-disk; the formula was tested against the Whitehall study; disk and action plan were evaluated in primary care. RESULTS--The system measures modifiable coronary risk from smoking, blood pressure, and blood cholesterol concentration by a sex and age related rank running from 1 (high risk, priority action) to 100 (low risk, general advice). The formula predicted outcome acceptably in the Whitehall study and is built into a circular slide rule. Only eight (11%) of 76 general practitioners and practice nurses surveyed already used risk factor scores. After evaluation most thought they should use one and proposed to incorporate the Dundee coronary risk-disk and the associated action plan into their routines. CONCLUSION--The Dundee coronary risk-disk readout of Dundee rank, standardised on a scale of 1 to 100 by age and sex, is a simple, valid means of assessing and monitoring modifiable coronary risk. It puts single risk factors (such as cholesterol concentration) in perspective and can aid selective testing. Understood by medical staff and patients, it should improve the efficiency and effectiveness of the high risk approach to coronary prevention.     

Adolescent smokers seen in general practice: health,lifestyle, physical measurements,and response to antismoking advice.

OBJECTIVE--To compare physical, lifestyle, and health characteristics of adolescent smokers and non-smokers and their initial response to anti-smoking counselling. DESIGN--Adolescents aged 13, 15, and 17 years were identified from age-sex registers and invited by letter for a general practice health check. SETTING--Three general practices in the MRC general practice research framework. MAIN OUTCOME MEASURES--Blood pressure, body mass index, saliva cotinine concentration, peak flow rate, alcohol consumption, exercise, duration of sleep, and stated persistent health problems. RESULTS--73% of the adolescents (491) attended for the health check. A total of 68 (14%) were regular smokers. By age 17 those who smoked regularly had a significantly lower systolic blood pressure than those who had never smoked regularly (by 6 mm Hg; p = 0.025) despite a significantly higher body mass index (by 1.5; p <0.001) [corrected]. Cotinine concentrations increased with smoking exposure, from 0.7 ng/ml when no family member smoked to 155 ng/ml in active smokers of six or more cigarettes a week. Significantly more regular smokers than never regular smokers drank greater than or equal to 8 g alcohol a day (chi 2 = 15.2 adjusted for age and sex p less than 0.001); regular smokers exercised less (1.0 hrs/week in boys and 0.8 hrs/week in girls v 3.4 hrs/week in boys and 2.2 hrs/week in girls; p less than 0.001) and slept less (8.0 hrs/night v 8.5 hrs/night at age 17; p less than 0.005). Persistent health problems, mostly asthma or allergic symptoms, were reported by 25% (17/68) of the smokers and 16% (60/381) of the non-smokers. Of the smokers given counselling, 60% (26/43) made an agreement with the practice doctor or nurse to give up smoking. CONCLUSION--General practice is an appropriate setting for adolescents to receive advice on healthy lifestyle, which should not focus solely on smoking.     

Effect of polyvinyl alcohol on survival and function of angora buck spermatozoa following cryopreservation

The aim of this study was to examine effects of polyvinyl alcohol (PVA) on buck semen quality. Seventy-five ejaculates were collected and diluted in Tris-egg yolk extender containing one of three PVA co-polymers of 9, 18 and 100 kDa. Five different concentrations 0.001, 0.01, 0.1, 1 and 2% of the PVA co-polymers were added to the extender with respected to the decreasing glycerol concentrations of 5, 4, 3, 3, 2% respectively. Following freeze-thaw, sperm motility, viability, acrosome-intact spermatozoa and mitochondrial membrane potentials were analysed. During freezing, sperm seeding temperature were recorded with a cryo-thermometer. PVA 2% glycerol group gained 8.2 ± 1 °C latent heat plateau difference comparing to control. Highest motility was found in PVA 18 kDa with regardless of the dosage (P < 0.001). All PVA copolymers gained higher motility independently in all other dosage groups (except PVA 2%) comparing to control (P < 0.001). Live spermatozoa rate between treatment groups were statistically insignificant (P = 0.953), however, when moribund sperm were gated out PVA 9 induced better protection with respect to other groups (P < 0.05). Intact acrosome rate was statically higher in PVA groups (P < 0.002) and subgroups (P < 0.001). Mitochondrial membrane potential was higher in all experimental groups comparing to control group (P < 0.001). PVA co-polymer concentrations of 0.01, 0.1, 1 and 2% v/v (PBS: PVA) decreased the concentration of glycerol required for freezing in a 100 ml volume by 0, 1, 2, 2, and 3% v/v from the control dose (5%), respectively. In conclusion, synthetic PVA-derived ice blocking agents offer new opportunities for improving the post-thaw buck sperm quality.     

Association between features of the insulin resistance syndrome and Alzheimer's disease independently of apolipoprotein E4 phenotype: cross sectional population based study.

OBJECTIVE: To determine the association between features of the insulin resistance syndrome and Alzheimer''s disease. DESIGN: Cross sectional population based study. SUBJECTS: 980 people aged 69 to 78 (349 men, 631 women). SETTING: Population of Kuopio, eastern Finland. MAIN OUTCOME MEASURES: Presence of features of the insulin resistance syndrome and diagnosis of Alzheimer''s disease by detailed neurological and neuropsychological evaluation. RESULTS: 46 (4.7%) subjects were classified as having probable or possible Alzheimer''s disease. In univariate analyses, apolipoprotein E4 phenotype (odds ratio; 95% confidence interval 3.24: 1.77 to 5.92), age (1.16; 1.05 to 1.29), low level of education (0.82; 0.72 to 0.93), low total cholesterol concentration (0.77; 0.59 to 1.00), high systolic blood pressure (1.01; 1.00 to 1.03), high fasting and 2 hour plasma glucose concentrations (1.11; 1.01 to 1.23 and 1.08; 1.03 to 1.13, respectively), high fasting and 2 hour insulin concentrations (1.05; 1.02 to 1.08 and 1.003; 1.00 to 1.01, respectively), and abnormal glucose tolerance (1.86; 1.23 to 2.80) were significantly associated with Alzheimer''s disease. In multivariate analysis including apolipoprotein E4 phenotype, age, education, systolic blood pressure, total cholesterol concentration, fasting glucose concentration, and insulin concentration, apolipoprotein E4 phenotype, age, education, total cholesterol, and insulin were significantly associated with Alzheimer''s disease. In 532 non-diabetic subjects without the e4 allele hyperinsulinaemia was associated with an increased risk for Alzheimer''s disease (prevalence of disease 7.5% v 1.4% in normoinsulinaemic subjects, P = 0.0004). In contrast, in the 228 with the e4 allele hyperinsulinaemia had no effect on the risk of disease (7.0% v 7.1%, respectively). CONCLUSION: Features of the insulin resistance syndrome are associated with Alzheimer''s disease independently of apolipoprotein E4 phenotype.     

Alcohol consumption,serum low density lipoprotein cholesterol concentration,and risk of ischaemic heart disease: six year follow up in the Copenhagen male study.

OBJECTIVES: To investigate the interplay between use of alcohol, concentration of low density lipoprotein cholesterol, and risk of ischaemic heart disease. DESIGN: Prospective study with controlling for several relevant confounders, including concentrations of other lipid fractions. SETTING: Copenhagen male study, Denmark. SUBJECTS: 2826 men aged 53-74 years without overt ischaemic heart disease. MAIN OUTCOME MEASURE: Incidence of ischaemic heart disease during a six year follow up period. RESULTS: 172 men (6.1%) had a first ischaemic heart disease event. There was an overall inverse association between alcohol intake and risk of ischaemic heart disease. The association was highly dependent on concentration of low density lipoprotein cholesterol. In men with a high concentration (> or = 5.25 mmol/l) cumulative incidence rates of ischaemic heart disease were 16.4% for abstainers, 8.7% for those who drank 1-21 beverages a week, and 4.4% for those who drank 22 or more beverages a week. With abstainers as reference and after adjustment for confounders, corresponding relative risks (95% confidence interval) were 0.4 (0.2 to 1.0; P<0.05) and 0.2 (0.1 to 0.8; P<0.01). In men with a concentration <3.63 mmol/l use of alcohol was not associated with risk. The attributable risk (95% confidence interval) of ischaemic heart disease among men with concentrations > or = 3.63 mmol/l who abstained from drinking alcohol was 43% (10% to 64%). CONCLUSIONS: In middle aged and elderly men the inverse association between alcohol consumption and risk of ischaemic heart disease is highly dependent on the concentration of low density lipoprotein cholesterol. These results support the suggestion that use of alcohol may in part explain the French paradox.     

Health Behaviors of Korean Gastric Cancer Survivors with Hypertension: A Propensity Analysis of KNHANES III-V (2005–2012)

ObjectiveThis study provides a comparison of health behaviors between gastric cancer survivors with hypertension and non-cancer subjects in Korea.MethodsData from the Korean National Health and Nutrition Examination Survey (KNHANES) for the period of 2005-2012 were used in this study. A propensity score matching method was used to compare health behaviors. Before the matching of propensity scores, the number of participants was 11034 (102 gastric cancer survivors and 10932 non-cancer participants). A 1:5 propensity score matching procedure yielded a total of 480 participants (80 gastric cancer survivors and 400 non-cancer participants) for the final analysis. Drinking, smoking, physical activity, antihypertensive medication adherence, self-reported diet control, and sodium intake accordance in the two groups were compared. A complex samples logistic regression analysis was conducted to assess any differences between the two groups.ResultsThe group of hypertensive gastric cancer survivors had lower alcohol consumption (OR = 0.30; 95% CI: 0.14-0.66; p-value = 0.003). They were more likely to be on dietary control than the control group (OR = 3.12; 95% CI: 1.60-6.10; p-value = 0.001). However, there was no significant (p > 0.05) difference in sodium intake accordance or other health behaviors (including medication adherence, smoking, and physical activity) between the two groups.ConclusionsOur results revealed that gastric cancer survivors with hypertension were more likely to be on dietary control with lower alcohol consumption than the control group. However, there was no significant difference in sodium intake accordance or other health behaviors between the two groups. Therefore, primary care physicians should inform cancer survivors about the appropriate health behaviors to reduce their risk of cardiovascular disease and improve their overall survival rate, even though they say they have been doing health behaviors.     

Obesity-related metabolic dysfunction in dogs: a comparison with human metabolic syndrome

ABSTRACT: BACKGROUND: Recently, metabolic syndrome (MS) has gained attention in human metabolic medicine given its associations with development of type 2 diabetes mellitus and cardiovascular disease. Canine obesity is associated with the development of insulin resistance, dyslipidaemia, and mild hypertension, but the authors are not aware of any existing studies examining the existence or prevalence of MS in obese dogs.Thirty-five obese dogs were assessed before and after weight loss (median percentage loss 29%, range 10-44%). The diagnostic criteria of the International Diabetes Federation were modified in order to define canine obesity-related metabolic dysfunction (ORMD), which included a measure of adiposity (using a 9-point body condition score [BCS]), systolic blood pressure, fasting plasma cholesterol, plasma triglyceride, and fasting plasma glucose. By way of comparison, total body fat mass was measured by dual-energy X-ray absorptiometry, whilst total adiponectin, fasting insulin, and high-sensitivity C-reactive protein (hsCRP) were measured using validated assays. RESULTS: Systolic blood pressure (P = 0.008), cholesterol (P = 0.003), triglyceride (P = 0.018), and fasting insulin (P < 0.001) all decreased after weight loss, whilst plasma total adiponectin increased (P = 0.001). However, hsCRP did not change with weight loss. Prior to weight loss, 7 dogs were defined as having ORMD, and there was no difference in total fat mass between these dogs and those who did not meet the criteria for ORMD. However, plasma adiponectin concentration was less (P = 0.031), and plasma insulin concentration was greater (P = 0.030) in ORMD dogs. CONCLUSIONS: In this study, approximately 20% of obese dogs suffer from ORMD, and this is characterized by hypoadiponectinaemia and hyperinsulinaemia. These studies can form the basis of further investigations to determine path genetic mechanisms and the health significance for dogs, in terms of disease associations and outcomes of weight loss.     

Health on the Web: Randomised Controlled Trial of Online Screening and Brief Alcohol Intervention Delivered in a Workplace Setting

BackgroundAlcohol misuse in England costs around £7.3 billion (US$12.2 billion) annually from lost productivity and absenteeism. Delivering brief alcohol interventions to employees as part of a health check may be acceptable, particularly with online delivery which can provide privacy for this stigmatised behaviour. Research to support this approach is limited and methodologically weak. The aim was to determine the effectiveness of online screening and personalised feedback on alcohol consumption, delivered in a workplace as part of a health check.ConclusionsThere was no evidence to support the use of personalised feedback within an online health check for reducing alcohol consumption among employees in this organisation. Further research is needed on how to engage a larger proportion of employees in screening.

Choosing the preventive workload in general practice: practical application of the Coronary Prevention Group guidelines and Dundee coronary risk-disk.

OBJECTIVE--To determine the workload implications for general practice of the Coronary Prevention Group and British Heart Foundation action plan for preventing heart disease. DESIGN--Computer simulation of plan, including calculation of Dundee risk scores, with data from OXCHECK trial. SUBJECTS--4759 patients aged 35-64 who had health checks during 1989-91. MAIN OUTCOME MEASURE--Effect of using different risk scores as thresholds on workload and coverage of patients at known risk. Thresholds of 6-20 were used for cholesterol screening (nearset) and 4-16 for special care (preset). RESULTS--On the basis of workload a nearset of 8 and preset of 12 would be reasonable. This implies cholesterol measurement in 1794 (37.7%) patients and special care in 1074 (22.6%). However, many patients with single risk factors were not allocated to special care at these thresholds: 11 (37.9%) patients with cholesterol concentrations > or = 10 mmol/l, 21 (33.9%) with systolic pressure > or = 180 mm Hg, and 213 (40.7%) heavy smokers (> 20 cigarettes/day) were missed. The distribution of scores was similar in those at established clinical risk, those with family history of heart disease, and others. CONCLUSION--The guidelines may help to make best use of resources within specific age-sex groups but sound protocols for unifactorial risk assessment and modification remain essential.     

Single dose vitamin A treatment in acute shigellosis in Bangladesh children: randomised double blind controlled trial.

OBJECTIVE: To evaluate the efficacy of a single large oral dose of vitamin A in treating acute shigellosis in children in Bangladesh. DESIGN: Randomised double blind controlled clinical trial. SETTING: Dhaka Hospital, International Centre for Diarrhoeal Disease Research, Bangladesh. SUBJECTS: 83 children aged 1-7 years with bacteriologically proved shigellosis but no clinical signs of vitamin A deficiency; 42 were randomised to treatment with vitamin A and 41 formed a control group. INTERVENTION: Children were given a single oral dose of 200,000 IU of vitamin A plus 25 IU vitamin E or a control preparation of 25 IU vitamin E. MAIN OUTCOME MEASURES: Clinical cure on study day 5 and bacteriological cure. RESULTS: Baseline characteristics of the subjects in the two treatment groups were similar. Significantly more children in the vitamin A group than in the control group achieved clinical cure (19/42 (45%) v 8/14 (20%); chi 2 = 5.14, 1 df, P = 0.02; risk ratio = 0.68 (95% confidence interval; 0.50 to 0.93)). When cure was determined bacteriologically, the groups had similar rates (16/42 (38%) v 16/41 (39%); chi 2 = 0.02, 1 df, P = 0.89; risk ratio = 0.98 (0.70 to 1.39)). CONCLUSIONS: Vitamin A reduces the severity of acute shigellosis in children living in areas where vitamin A deficiency is a major public health problem.     

Online Health Check for Reducing Alcohol Intake among Employees: A Feasibility Study in Six Workplaces across England

Background

Most hazardous and harmful drinkers are of working age and do not seek help with their drinking. Occupational health services are uniquely placed to universally screen employees across the range of socioeconomic and ethnic groups. The aim was to explore the feasibility and acceptability of offering electronic screening and brief intervention for alcohol misuse in the context of a health check in six different workplace settings.

Methods and Findings

Employees were recruited from six workplaces across England, including three local authorities, one university, one hospital and one petro-chemical company. A total of 1,254 (8%) employees completed the health check and received personalised feedback on their alcohol intake, alongside feedback on smoking, fruit and vegetable consumption and physical activity. Most participants were female (65%) and of ‘White British’ ethnicity (94%), with a mean age of 43 years (SD 11). Participants were mostly in Intermediate occupations (58%), followed by Higher managerial / professional (39%) and Routine and manual occupations (2%). A quarter of participants (25%) were drinking at hazardous levels (33% male, 21% female), which decreased with age. Sixty-four percent (n=797) of participants completed online follow-up at three months. Most participants were supportive of workplaces offering employees an online health check (95%), their preferred format was online (91%) and many were confident of the confidentiality of their responses (60%). Whilst the feedback reminded most participants of things they already knew (75%), some were reportedly motivated to change their behaviour (13%).

Conclusions

Online health screening and personalised feedback appears feasible and acceptable, but challenges include low participation rates, potentially attracting ‘worried well’ employees rather than those at greatest health risk, and less acceptance of the approach among older employees and those from ethnic minority backgrounds and routine or manual occupations.     

Utility of the Framingham risk score to predict the presence of coronary atherosclerosis in patients with rheumatoid arthritis

The prevalence of ischemic heart disease and atherosclerosis is increased in patients with rheumatoid arthritis (RA). In the general population, but not in patients with systemic lupus erythematosus, the Framingham risk score identifies patients at increased cardiovascular risk and helps determine the need for preventive interventions. We examined the hypothesis that the Framingham score is increased and associated with coronary-artery atherosclerosis in patients with RA. The Framingham score and the 10-year cardiovascular risk were compared among 155 patients with RA (89 with early disease, 66 with long-standing disease) and 85 control subjects. The presence of coronary-artery calcification was determined by electron-beam computed tomography. The Framingham score was compared in patients with RA and control subjects, and the association between the risk score and coronary-artery calcification was examined in patients. Patients with long-standing RA had a higher Framingham score (14 [11 to 18]) (median [interquartile range]) compared to patients with early RA (11 [8 to 14]) or control subjects (12 [7 to 14], P < 0.001). This remained significant after adjustment for age and gender (P = 0.015). Seventy-six patients with RA had coronary calcification; their Framingham risk score was higher (14 [12 to 17]) than that of 79 patients without calcification (10 [5 to 14]) (P < 0.001). Furthermore, a higher Framingham score was associated with a higher calcium score (odds ratio [OR] = 1.20, 95% confidence interval [CI] 1.12 to 1.29, P < 0.001), and the association remained significant after adjustment for age and gender (OR = 1.15, 95% CI 1.02 to 1.29, P = 0.03). In conclusion, a higher Framingham risk score is independently associated with the presence of coronary calcification in patients with RA.     

Serum cholesterol concentration and death from suicide in men: Paris prospective study I.

OBJECTIVE: To investigate whether low serum cholesterol concentration or changing serum cholesterol concentration is associated with risk of suicide in men. DESIGN: Cohort study with annual repeat measurements of serum cholesterol concentration (for up to four years). SETTING: Paris, France. SUBJECTS: 6393 working men, aged 43-52 in 1967-72, who had at least three measurements of serum cholesterol concentration. MAIN OUTCOME MEASURES: Individual change over time in serum cholesterol concentration (estimated using within person linear regression method); death from suicide during average of 17 years'' follow up after last examination. RESULTS: 32 men committed suicide during follow up. After adjustment for age and other factors, relative risk of suicide for men with low average serum cholesterol concentration (< 4.78 mmol/l) compared with those with average serum cholesterol concentration of 4.78-6.21 mmol/l was 3.16 (95% confidence interval 1.38 to 7.22, P = 0.007). Men whose serum cholesterol concentration decreased by more than 0.13 mmol/l a year had multivariate adjusted relative risk of 2.17 (0.97 to 4.84, P = 0.056) compared with those whose cholesterol remained stable (change of < or = 0.13 mmol/l a year). CONCLUSION: Both low serum cholesterol concentration and declining cholesterol concentration were associated with increased risk of death from suicide in men. Although there is some evidence in favour of a concomitant rather than a causal effect for interpreting these associations, long term surveillance of subjects included in trials of lipid lowering treatments seems warranted.
