RESUMO
AIMS: To explore the confounding effects of early family factors shared by siblings and cardiovascular risk factors in midlife on the educational differences in mortality from cardiovascular disease (CVD). METHODS: Data from national and regional health surveys in Norway (1974-2003) were linked with data from the Norwegian Family Based Life Course Study, the National Educational Registry and the Cause of Death Registry. The study population consisted of participants with at least one full sibling among the health survey participants ( n=271,310). Data were available on CVD risk factors, including weight, height, blood pressure, total cholesterol and smoking. RESULTS: The hazards ratio (HR) of CVD mortality was 3.44 (95% confidence interval (CI) 2.98-3.96) in the lowest educational group relative to the highest. The HRs were little altered in the within-sibship analyses. Adjusted for risk factors, the HR for CVD mortality in the cohort analyses was 2.05 (CI 1.77-2.37) in the lowest educational group relative to the highest. The respective HR in the within-sibship analyses was 2.46 (CI 1.48-2.24). CONCLUSIONS: Using a sibling design, we did not find that the association between education and CVD mortality was confounded by early life factors shared by siblings, but it was explained to a large extent by CVD risk factors. These results suggest that reducing levels of CVD risk factors could have the greatest effect on mortality in less well-educated people.

BACKGROUND/OBJECTIVES: Previous studies have demonstrated associations between some early-life exposures and later obesity, but most have used body mass index in childhood or adulthood as the outcome. The objective of this study was to investigate whether early-life exposures were associated with directly measured fat and lean mass in adolescence. SUBJECTS/METHODS: This study used data on 4750 mother-offspring pairs, collected as a part of the Avon Longitudinal Study of Parents and Children, Bristol, UK between 1991 and 1992; associations between behavioural exposures occurring from conception up to 5 years of age (maternal and paternal smoking during pregnancy, breastfeeding, age at introduction to solids, dietary patterns and physical inactivity during early childhood) and offspring body composition measured by dual-energy X-ray absorptiometry at ~15 years were assessed. RESULTS: After full adjustment for potential confounders, maternal smoking during pregnancy, having a junk food diet and spending more time watching television in early childhood were all associated with higher fat mass at age 15, whereas maternal smoking, having a healthy diet and playing computer games more frequently in early childhood were all associated with a higher lean mass at age 15. Associations with paternal smoking were generally weaker for both fat and lean mass, but as there was no strong statistical evidence for maternal vs paternal differences, confounding by social factors rather than a direct effect of maternal smoking cannot be ruled out. Early feeding was not associated with fat or lean mass at age 15. CONCLUSIONS: This study does not provide compelling evidence for associations between most early-life factors and body composition in adolescence. However, possible associations with dietary patterns and physical inactivity in early childhood require further investigation in other cohorts that have direct measurements of adolescent body composition.
RESUMO
BACKGROUND: Socioeconomic gradients in adiposity were not present during childhood for previous generations, but have emerged in contemporary children. It is unknown whether this translates to socioeconomic gradients in associated cardiovascular risk factors in children, with consequent implications for inequalities in coronary heart disease (CHD) and diabetes when these children reach adulthood. METHODS: Using data from 7772 participants aged 10-years from the Avon Longitudinal Study of Parents and Children, we examined the association between maternal education and a large number of cardiovascular risk factors (cholesterol, triglycerides, high-density lipoprotein, apolipoprotein, adiponectin, leptin, C-reactive protein (CRP), interleukin-6 (IL-6) and systolic and diastolic blood pressure), and examined whether inequalities were mediated by adiposity, measured by dual energy X-ray absorptiometry (DXA)-assessed total fat mass. RESULTS: There were socioeconomic differences in a number of the cardiovascular risk factors (apolipoprotein B, systolic and diastolic blood pressure, CRP, leptin and IL-6). Inequalities were greater in girls than boys. Inequalities in CRP and leptin were completely mediated by adiposity. Inequalities in other cardiovascular risk factors were partially mediated by adiposity. CONCLUSION: This study showed important socioeconomic inequalities in adiposity and associated cardiovascular risk factors in a contemporary UK population of 10-year-old children. Differences between contemporary children and previous generations in the socioeconomic patterning of cardiovascular risk factors suggest future adults may have greater inequalities in diabetes and CHD than current adults. These findings highlight the importance of interventions aimed at preventing obesity in childhood, particularly among those of lower socioeconomic position.

BACKGROUND: Overconsumption of alcohol affects health. Data from men from the West of Scotland Collaborative study were analysed to see how reported alcohol was related to acute and mental health hospital admissions. METHODS: Men (N = 5772) from a prospective cohort study located in 27 workplaces in West and Central Scotland were screened when aged 35-64 in 1970-3. The number of acute and mental health admissions and bed-days were calculated by alcohol category (none, 1-7, 8-14, 15-21, 22-34 and 35 or more units per week) to the end of 2005. Specific causes were coronary heart disease (CHD), stroke, respiratory diseases and alcohol-related. RESULTS: Men who consumed 22 or more units per week had a 20% higher rate of acute admissions than non-drinkers. The number of bed-days were higher for men drinking eight or more units and increased with consumption, with the highest category having a 58% higher rate of bed-days than non-drinkers. Non-drinkers had the highest admissions for CHD. For stroke, drinkers of 15 or more units had higher admissions and higher number of bed-days and these increased with increasing consumption. Respiratory admissions were higher for drinkers of 22 or more units and bed-days were higher for drinkers of 15 or more units. Alcohol-related admissions and number of bed-days generally increased with consumption. Mental health admissions and number of bed-days were raised for drinkers of 22 or more units with a suggestion of a J-shaped relationship. CONCLUSION: Alcohol consumption has a substantial effect on acute and mental health admissions and bed-days.

OBJECTIVES: To investigate epidemiological, social, diagnostic and economic aspects of chlamydia screening in non-genitourinary medicine settings. METHODS: Linked studies around a cross-sectional population-based survey of adult men and women invited to collect urine and (for women) vulvovaginal swab specimens at home and mail these to a laboratory for testing for Chlamydia trachomatis. Specimens were used in laboratory evaluations of an amplified enzyme immunoassay (PCE EIA) and two nucleic acid amplification tests [Cobas polymerase chain reaction (PCR), Becton Dickinson strand displacement amplification (SDA)]. Chlamydia-positive cases and two negative controls completed a risk factor questionnaire. Chlamydia-positive cases were invited into a randomised controlled trial of partner notification strategies. Samples of individuals testing negative completed psychological questionnaires before and after screening. In-depth interviews were conducted at all stages of screening. Chlamydia transmission and cost-effectiveness of screening were investigated in a transmission dynamic model. SETTING AND PARTICIPANTS: General population in the Bristol and Birmingham areas of England. In total, 19,773 women and men aged 16-39 years were randomly selected from 27 general practice lists. RESULTS: Screening invitations reached 73% (14,382/19,773). Uptake (4731 participants), weighted for sampling, was 39.5% (95% CI 37.7, 40.8%) in women and 29.5% (95% CI 28.0, 31.0%) in men aged 16-39 years. Chlamydia prevalence (219 positive results) in 16-24 year olds was 6.2% (95% CI 4.9, 7.8%) in women and 5.3% (95% CI 4.4, 6.3%) in men. The case-control study did not identify any additional factors that would help target screening. Screening did not adversely affect anxiety, depression or self-esteem. Participants welcomed the convenience and privacy of home-sampling. The relative sensitivity of PCR on male urine specimens was 100% (95% CI 89.1, 100%). The combined relative sensitivities of PCR and SDA using female urine and vulvovaginal swabs were 91.8% (86.1, 95.7, 134/146) and 97.3% (93.1, 99.2%, 142/146). A total of 140 people (74% of eligible) participated in the randomised trial. Compared with referral to a genitourinary medicine clinic, partner notification by practice nurses resulted in 12.4% (95% CI -3.7, 28.6%) more patients with at least one partner treated and 22.0% (95% CI 6.1, 37.8%) more patients with all partners treated. The health service and patients costs (2005 prices) of home-based postal chlamydia screening were 21.47 pounds (95% CI 19.91 pounds, 25.99) per screening invitation and 28.56 pounds (95% CI 22.10 pounds, 30.43) per accepted offer. Preliminary modelling found an incremental cost-effectiveness ratio (2003 prices) comparing screening men and women annually to no screening in the base case of 27,000 pounds/major outcome averted at 8 years. If estimated screening uptake and pelvic inflammatory disease incidence were increased, the cost-effectiveness ratio fell to 3700 pounds/major outcome averted. CONCLUSIONS: Proactive screening for chlamydia in women and men using home-collected specimens was feasible and acceptable. Chlamydia prevalence rates in men and women in the general population are similar. Nucleic acid amplification tests can be used on first-catch urine specimens and vulvovaginal swabs. The administrative costs of proactive screening were similar to those for opportunistic screening. Using empirical estimates of screening uptake and incidence of complications, screening was not cost-effective.

OBJECTIVES: To describe the socioeconomic distribution of risk factors for cardiorespiratory disease and diabetes in employed women and men in the late 1960s. STUDY DESIGN AND METHODS: Cross-sectional data were collected from 3345 General Post Office (GPO) employees in London, via a questionnaire and clinical examination, between October 1966 and April 1967. RESULTS: Our occupational grade classification conformed to expected patterns of greater car ownership and gardening among higher-grade women and men, and greater height in higher-grade men (highest-lowest grade 175.0-170.7 cm, P<0.001). A strong inverse grade gradient in bronchitis (2.1-9.4%, P<0.001) and a strong positive gradient in FEV1 (3.10-2.58l, P<0.001) were observed in men, although smoking was less consistently associated with grade. There was no consistent inverse association between grade and any cardiovascular risk factor in either sex, but strong inverse gradients in prevalence of impaired glucose tolerance (IGT) (5.1-18.2%, P<0.001) and 2-h glucose (4.14-4.25 mmol/l, P<0.001) in non-diabetic men. Using car ownership as an alternative measure of socioeconomic position, findings in men were replicated for respiratory measures, IGT and 2-h glucose prevalence. Inverse gradients were additionally observed for blood pressure, cholesterol and electrocardiogram abnormalities. CONCLUSIONS: The GPO study confirms existing evidence of socioeconomic gradients in respiratory risk factors and provides new evidence of gradients in risk factors for diabetes in men. Although there was no conclusive evidence of an occupational gradient in any cardiovascular risk factor, car ownership was a good indicator of lower risk in men. No socioeconomic gradients in cardiorespiratory or diabetic risk factors were observed in women.

BACKGROUND: Screening has been recommended to reduce the prevalence and morbidity associated with genital chlamydia infection in the United Kingdom. METHODS: We describe the rationale and study design of the Chlamydia Screening Studies (ClaSS), a collaborative project designed to evaluate screening outside genitourinary medicine clinics. A non-selective, active screening approach in 16-39 year olds randomly sampled from 27 general practice lists in the Bristol and Birmingham areas formed the basis of interlinked studies: a case-control study was used to investigate factors to improve the targeting of screening; participants with chlamydia were invited to enroll in a randomised controlled trial to evaluate partner notification conducted in primary care; and laboratory based studies were used to assess the best specimens and tests. We also explored psychosocial effects of screening and partner notification and modelled the cost effectiveness of the programme. CONCLUSION: Results from four pilot practices show that mailing of specimens for chlamydia testing is feasible but that it is difficult to achieve high response rates with postal screening. The high prevalence of asymptomatic infection in men suggests that efforts to screen men for chlamydia should be strengthened.

AIMS: To investigate socio-economic inequalities in diabetes complications, and to examine factors that may explain these differences. METHODS: Cross-sectional questionnaire survey of 770 individuals with diabetes among 40 general practices in Avon and Somerset. General practice, optometrist and eye hospital records over time (median 7 years) were analysed. Slope indices of inequality, odds ratios and incidence rate ratios were calculated to estimate the magnitude of inequality between the most and least educated, and the highest and lowest earning patients, adjusted for age, sex and type of diabetes, and clustering of outcomes within practices. RESULTS: The least educated patients were more likely than the most educated patients to have diabetic retinopathy [adjusted odds ratio (OR) 4.3; 95% confidence interval 0.8, 23.7] and heart disease (adjusted OR 3.6; 1.1, 11.8), had higher HbA1c levels (adjusted slope index of inequality 0.9; 0.3, 1.5), felt that diabetes more adversely affected their social and personal lives (adjusted slope index of inequality 0.8; 0.5, 1.1 Diabetes Care Profile units), were more likely to be recorded as non-compliant by their health professionals, and had lower rates of hospital attendance (adjusted rate ratio 0.43; 0.26, 0.71). However, they did not see themselves as less compliant, and had higher general practice attendance rates (adjusted rate ratio 1.5; 1.1, 2.2). CONCLUSIONS: Less educated and lower earning individuals with diabetes bear a larger burden of morbidity but use hospital care less. Health service resource allocation should reflect the distribution of chronic illness.

Health impact assessment (HIA) seeks to expand evaluation of policy and programmes in all sectors, both private and public, to include their impact on population health. While the idea that the public's health is affected by a broad array of social and economic policies is not new and dates back well over two centuries, what is new is the notion-increasingly adopted by major health institutions, such as the World Health Organisation (WHO) and the United Kingdom National Health Services (NHS)-that health should be an explicit consideration when evaluating all public policies. In this article, it is argued that while HIA has the potential to enhance recognition of societal determinants of health and of intersectoral responsibility for health, its pitfalls warrant critical attention. Greater clarity is required regarding criteria for initiating, conducting, and completing HIA, including rules pertaining to decision making, enforcement, compliance, plus paying for their conduct. Critical debate over the promise, process, and pitfalls of HIA needs to be informed by multiple disciplines and perspectives from diverse people and regions of the world.

OBJECTIVE: To study the impact of childhood and adulthood social circumstances on cause specific adult mortality. DESIGN: Census data on housing conditions from 1960 and Personal Register income data for 1990 were linked to 1990-94 death registrations, and relative indices of inequality were computed for housing conditions in 1960 and for household income in 1990. PARTICIPANTS: The 128 723 inhabitants in Oslo aged 31-50 years in 1990. MAIN RESULTS: Adulthood mortality was strongly associated with both childhood and adulthood social circumstances among both men and women. Cardiovascular disease mortality was more strongly associated with childhood than with adulthood social circumstances, while the opposite was found for psychiatric and accidental/violent mortality. Smoking related cancer mortality was related to both adulthood and childhood social circumstances in men, but considerably more strongly to adult social circumstances. CONCLUSIONS: Childhood social circumstances have an important influence on cardiovascular disease risk in adulthood. Current increases in child poverty that have been seen in Norway over the past two decades could herald unfavourable future trends in adult health.

STUDY OBJECTIVE: Despite an overall decline in mortality rates, the social gradient in mortality has increased over the past two decades. However, evidence on trends in morbidity and cardiovascular risk factors indicates that socioeconomic differences are static or narrowing. The objective of this study was to investigate morbidity and cardiovascular risk factor trends in white collar British civil servants. DESIGN: Self rated health, longstanding illness, minor psychiatric morbidity (General Health Questionnaire (GHQ) 30 score, GHQ caseness and GHQ depression subscale), cholesterol, diastolic and systolic blood pressure, body mass index, alcohol over the recommended limits, and smoking were collected at baseline screening (1985-88) and twice during follow up (mean length of follow up 5.3 and 11.1 years). Employment grade gradients in these measures at each phase were compared. SETTING: Whitehall II, prospective cohort study. PARTICIPANTS: White collar women and men aged 35-55, employed in 20 departments at baseline screening. Analyses included 6770 participants who responded to all three phases. RESULTS: Steep employment grade gradients were observed for most measures at second follow up. In general, there was little evidence that employment grade gradients have increased over the 11.1 years of follow up, but marked increases in the gradient were observed for GHQ score (p<0.001) and depression (p=0.05) in both sexes and for cholesterol in men (p=0.01). CONCLUSIONS: There is little evidence of an increase in inequality for most measures of morbidity and cardiovascular risk factors in white collar civil servants over the 11.1 years to 1998. Inequalities have increased significantly for minor psychiatric morbidity in both sexes and for cholesterol in men.

The Young Hearts (YH) Project is an ongoing study of biological and behavioural risk factors for cardiovascular disease in a representative sample of young people from Northern Ireland, a region of high coronary mortality. This article describes the cross-sectional clinical, dietary and lifestyle data obtained from individuals (aged 20-25 y) who participated in phase 3 of the project (YH3). A total of 489 individuals (251 males, 238 females) participated in YH3 (48.2% response rate). Some 31.1% of participants at YH3 were overweight (BMI >25 kg/m(2)) with 4.4% of males and 8.0% of females were obese (BMI >30 kg/m(2)). More females than males had a very poor fitness (55.0 vs 22.1%, chi-squared 51.70, d.f. 1, P<0.001) and did not participate in any sporting or exercise activity (38.4 vs 24.9%, chi-squared 10.26, d.f. 1, P=0.001). Over 20% of participants had a raised total serum cholesterol (>5.2 mmol/l). More females had a raised serum LDL-cholesterol (>3.0 mmol/l) than males (44.6 vs 34.6%, chi-squared 4.39, d.f. 1, P<0.05). Over 46% of participants reported energy intakes from fat above recommended levels, and 68.5% of participants had saturated fat intakes above those recommended (Dietary reference values for food energy and nutrients for the United Kingdom. HMSO: London, 1991). Just over half of the study population reported alcohol intakes in excess of recommended sensible limits set by the Royal College of Physicians (A great and growing evil: the medical consequences of alcohol abuse. Tavistock: London, 1987), with 36.7% of males and 13.4% of females reporting intakes over twice these recommended limits. A total of 37% of the study population smoked. During young adulthood, individuals may be less amenable to attend a health-related study and recruitment of participants to the current phase of the study proved a major problem. However, these data constitute a unique developmental record from adolescence to young adulthood in a cohort from Northern Ireland and provide additional information on the impact of early life, childhood and young adulthood on the development of risk for chronic disease.

STUDY OBJECTIVES: To examine associations between five measures of housing conditions during childhood and subsequent mortality from all causes, coronary heart disease, stroke, and cancer. DESIGN: Historical cohort study. SETTING: Data on housing conditions were collected from survey centres in 16 areas of England and Scotland. PARTICIPANTS: Children of families participating in the Carnegie Survey of Family Diet and Health in pre-war Britain (1937-1939). Analyses are based on a subset of 4168 people who were traced and alive on 1 January 1948. MAIN RESULTS: Poorer housing conditions were generally associated with increased adult mortality. After adjustment for childhood and adult socioeconomic factors, statistically significant associations were only found between lack of private indoor tapped water supply and increased mortality from coronary heart disease (hazard ratio 1.73, (95% CI 1.13, 2.64); and between poor ventilation and overall mortality (hazard ratio for people from households with poorest ventilation relative to best ventilation 1.30, 95% CI 0.97, 1.74). CONCLUSIONS: This study provides evidence that associations between housing conditions in childhood and mortality from common diseases in adulthood are not strong, but are in some respects distinguishable from those of social deprivation.

PURPOSE: To describe the prevalence of vision-related quality of life (VR-QOL) impairment in an elderly UK population sample. METHOD: The survey, using the VCM1 questionnaire, was based on an age- and sex-stratified random population sample of 2783 individuals aged 55 years or over. RESULTS: One thousand eight hundred and forty-six (69.7%) of 2647 eligible subjects responded. One thousand six hundred and eighty-three individuals completed all 10 VCM1 items. Overall the prevalence of a VCM1 score >2.0 ('more than a little' concern about vision) was 4.6% (95% CI = 3.7% to 5.7%), leading to an estimate of more than 550,000 individuals in England with substantial VR-QOL impairment. The prevalence increased with age from 2.1% in the 55-64 year age group to 17.9% in the group aged 85 years and older. The prevalence also increased as social class became lower, from 0 in social class I to 10.2% in social class V, and increased with increasing material deprivation, from 1.2% in the most affluent quintile to 6.8% in the most deprived quintile. Multivariable logistic regression analysis showed that age (p = 0.0001), decreasing social class (p = 0.03) and increasing material deprivation (p = 0.008) were independently associated with VR-QOL impairment (VCM1 score >2.0), whilst gender and means of questionnaire administration were not associated with VR-QOL impairment at the 5% level. CONCLUSIONS: The findings suggest a substantial national prevalence of VR-QOL impairment, and are consistent with earlier studies linking ocular disease with social deprivation. Consideration should be given to directing resources more carefully towards groups at higher risk of VR-QOL impairment, in particular the very elderly and socially deprived.

OBJECTIVE: To investigate the association between the severity of hip pain and disability, and a number of measures of socioeconomic position, using a range of individual and ecological socioeconomic indicators. DESIGN: Interviewer administered and self completed questionnaires on symptoms of pain and disability, general health and socioeconomic indicators, completed by people reporting hip pain in a cross sectional, postal, screening questionnaire. SETTING: 40 general practices from inner city, suburban and rural areas of south west England. PARTICIPANTS: 954 study participants who had reported hip pain in a postal questionnaire survey of 26,046 people aged 35 and over, selected using an age/sex stratified random probability sample. DATA: Individual indicators of socioeconomic position: social class based on occupation, maximum educational attainment, car ownership, gross household income, manual or non-manual occupation and living alone. Area level measures of socioeconomic position: Townsend scores for material deprivation at enumeration district level; urban or rural location based on the postcode of residence. Severity of hip disease, measured by the pain, disability and independence components of the New Zealand score for major joint replacement. Self reported comorbidity validated using general practice case notes and summary measures of general health. MAIN RESULTS: Increasing disease severity was strongly associated with increasing age and a variety of measures of general health, including comorbidity. The data provide considerable evidence for the systematic association of increased severity of hip disease with decreasing socioeconomic position. Measures of socioeconomic position that were systematically associated with increasing disease severity, standardised for age and sex, included educational attainment (relative index of inequality 1.95 (95% confidence intervals 1.29 to 2.62) and income (relative index of inequality 4.03 (95% confidence intervals 3.43 to 4.64). Those with access to a car (mean disease severity 15.5) had statistically significant lower severity of hip disease than those without (mean 17.5, p < 0.01). Similar results were found for access to higher or further education and living with others. For a given level of income, people with greater comorbidity had more severe hip pain and disability. The gradient in disease severity between rich and poor was steepest among those with the most comorbidity. CONCLUSIONS: People with lower socioeconomic position experience a greater severity of hip disease. The poorest sector of the population seem to be in double jeopardy: they not only experience a greater burden of chronic morbidity but also a greater severity of hip disease. This study has implications for health care provision, if the National Health Service is to live up to its principle of equal treatment for equal medical need.
