Contribution of deaths related to alcohol use of socioeconomic variation in mortality: register based follow up study.

OBJECTIVE: To estimate the contribution of excessive alcohol use to socioeconomic variation in mortality among men and women in Finland. DESIGN: Register based follow up study. SUBJECTS: The population covered by the 1985 and 1990 censuses, aged > or = 20 in the follow up period 1987-93. MAIN OUTCOME MEASURES: Total mortality and alcohol related mortality from all causes, from diseases, and from accidents and violence according to socioeconomic position. The excess mortality among other classes compared with upper non-manual employees and differences in life expectancy between the classes were used to measure mortality differentials. RESULTS: Alcohol related mortality constituted 11% of all mortality among men aged > or = 20 and 2% among women and was higher among manual workers than among other classes. It accounted for 14% of the excess all cause mortality among manual workers over upper non-manual employees among men and 4% among women and for 24% and 9% of the differences in life expectancy, respectively. Half of the excess mortality from accidents and violence among male manual workers and 38% among female manual workers was accounted for by alcohol related deaths, whereas in diseases the role of alcohol was modest. The contribution of alcohol related deaths to relative mortality differentials weakened with age. CONCLUSIONS: Class differentials in alcohol related mortality are an important factor in the socioeconomic mortality differentials in Finland, especially among men, among younger age groups, and in mortality from accidents and violence.     

Plasma cholesterol,coronary heart disease,and cancer in the Renfrew and Paisley survey.

The relation between plasma cholesterol concentration and mortality from coronary heart disease, incidence of and mortality from cancer, and all cause mortality was studied in a general population aged 45-64 living in the west of Scotland. Seven thousand men (yielding 653 deaths from coronary heart disease, 630 new cases of cancer, and 463 deaths from cancer) and 8262 women (322 deaths from coronary heart disease, 554 new cases of cancer, and 395 deaths from cancer) were examined initially in 1972-6 and followed up for an average of 12 years. All cause mortality was not related to plasma cholesterol concentration. This was largely a consequence of a positive relation between cholesterol values and mortality from coronary heart disease being balanced by inverse relations between cholesterol and cancer and between cholesterol and other causes of death. These changes were highly significant for coronary heart disease and cancer in men and significant for coronary heart disease and other causes of death in women. The inverse association between cholesterol concentration and cancer in men was strongest for lung cancer, was not merely a function of the age at which a subject died, was present for the incidence of cancer as well as mortality from cancer, and persisted when new cases or deaths occurring within the first four years of follow up were excluded from the analysis.     

Non-fasting serum triglyceride concentration and mortality from coronary heart disease and any cause in middle aged Norwegian women.

OBJECTIVE--To study the association between non-fasting serum triglyceride concentrations and mortality in women from coronary and cardiovascular disease and all causes. DESIGN--Follow up by ambulatory teams of men and women who underwent cardiovascular screening for a mean of 14.6 years. SETTING--National health screening service in Norway. SUBJECTS--25,058 men and 24,535 women aged 35-49 years. MAIN OUTCOME MEASURE--Predictive value of non-fasting serum triglyceride concentrations. RESULTS--At initial screening total serum cholesterol concentration, serum triglyceride concentration, blood pressure, height, and weight were measured, and self reported information about smoking habits, physical activity, and time since last meal were recorded. During subsequent follow up 108 women died from coronary heart disease, 238 from cardiovascular diseases, and 931 from all causes. In women mortality increased steadily with increasing triglyceride concentration for all three causes of death. With the proportional hazards model and adjustment for age, systolic blood pressure, total cholesterol concentration, time since last meal, and number of cigarettes a day the relative risk between triglyceride concentration > or = 3.5 mmol/l and < 1.5 mmol/l was 4.7 (95% confidence interval 2.5 to 8.9) for deaths from coronary heart disease, 3.0 (1.9 to 4.8) for deaths from cardiovascular disease, 2.3 (1.8 to 2.9) for total deaths in all women. CONCLUSIONS--A raised non-fasting concentration of triglycerides is an independent risk factor for mortality from coronary heart disease, cardiovascular disease, and any cause mortality among middle aged Norwegian women in contrast to what is seen in men.     

Are low cholesterol values associated with excess mortality?

The relation between cholesterol concentration and mortality was studied prospectively over 17 years in 630 New Zealand Maoris aged 25-74. The dead or alive state of each person was determined in 1981. The causes of death were divided into three categories: cancer, cardiovascular disease, and "other." Using univariate and both linear and non-linear multivariate methods of analysis for survivorship data, significant inverse relations with serum cholesterol were found for total mortality in women, for mortality from cancer in men and women, and for other causes of mortality in both men and women. The inverse and non-linear association with total mortality in women remained significant when deaths in the first five years of follow up were excluded. This suggests that the association was not explained by undetected illness causing low cholesterol concentrations at the time of initial examination.     

Physiological changes in successive pregnancies and birth‐order effects

Abstract

An analysis of mortality rates documents that the well‐established female advantage in mortality continues to increase. Data from the U.S. census show that the sex differential in mortality has increased from 1.69 in 1963 to 1.82 in 1976. The age groups which show the most pronounced changes are youth (15–24), young adults (25–34), and old persons (75–84). Following Enterline (1961), we assess the major causes of death within each of these age groups in terms of their relative contributions to changing sex ratios. The major factors among young persons, apart from declining maternal mortality, are found to involve violent deaths, especially traffic accidents and suicide. Among old persons, death rates in general have declined, but advances in medical technology appear to have been more beneficial for older women than for older men, supporting the hypothesis of a biological superiority among women. However, death rates for malignant neoplasms have increased for older women as well as older men, suggesting that changing life styles may eventually have an impact on female mortality. The data suggest a need for additional research concerning the increase in violent deaths among young women and the potential increase in cancer deaths among older women.     

Impact of cardiovascular risk factors on coronary heart disease and mortality among middle aged diabetic men: a general population study.

OBJECTIVE--To investigate the effect of cardiovascular risk factors on coronary heart disease and all cause mortality in middle aged diabetic men. DESIGN--Prospective population study based on data collected from second screening (from 1974 to 1977) in the multifactor primary prevention trial and follow up until March 1983. SETTING--Gothenburg, Sweden. SUBJECTS--6897 Men aged 51 to 59, of whom 232 were self reported diabetics and 6665 were non-diabetic; none had a history of myocardial infarction. MAIN OUTCOME MEASURES--Incidences of coronary heart disease and mortality from all causes. RESULTS--Diabetic men with a serum cholesterol concentration greater than 7.3 mmol/l had a significantly higher incidence of coronary heart disease during follow up than those with a concentration less than or equal to 5.5 mmol/l (28.3% v 5.4%; p = 0.020); corresponding figures for non-diabetic men were 9.4% and 2.4% respectively. In multivariate logistic regression analyses serum cholesterol concentration and smoking habit were independent predictors of coronary heart disease (odds ratio serum cholesterol concentration 6.1 (95% confidence interval 2.1 to 17.6) current smoking 2.9 (1.1 to 7.5)) and of all cause mortality (3.2 (1.3 to 7.9), 3.0 (1.4 to 6.7) respectively) in diabetic men whereas systolic blood pressure, body mass index, family history, marital state, and alcohol abuse were not. Low occupational class was an independent predictor of mortality (2.4 (1.01 to 5.5)), but not of coronary heart disease, in diabetic men. CONCLUSIONS--Middle aged diabetic men with hypercholesterolaemia are at very high risk of developing coronary heart disease and of dying prematurely. Lowering serum cholesterol concentration in such subjects seems to be warranted.     

Stressful life events,social support,and mortality in men born in 1933.

OBJECTIVE--To examine relations between stressful life events and mortality in middle aged men. DESIGN--Prospective population study. Data on stressful life events, social network, occupation, and other psychosocial factors derived from self administered questionnaires. Mortality data obtained from official registers. SETTING--City of Gothenburg, Sweden. SUBJECTS--752 men from a random population sample of 1016 men aged 50. MAIN OUTCOME MEASURE--Mortality from all causes during seven years'' follow up. RESULTS--Life events which had occurred in the year before the baseline examination were significantly associated with mortality from all causes during seven years'' follow up. Of the men who had experienced three or more events during the past year 10.9% had died compared with 3.3% among those with no life events (odds ratio 3.6; 95% confidence interval 1.5 to 8.5). The association between recent life events and mortality remained true after smoking, self perceived health, occupational class, and indices of social support were controlled for. Many of the deaths were alcohol related, but the number of deaths was too small to allow for analyses of specific causes of death. The association between life events and mortality was evident only in men with low emotional support. CONCLUSION--Stressful life events are associated with high mortality in middle aged men. Men with adequate emotional support seem to be protected.     

Assessing possible hazards of reducing serum cholesterol.

OBJECTIVE--To assess whether low serum cholesterol concentration increases mortality from any cause. DESIGN--Systematic review of published data on mortality from causes other than ischaemic heart disease derived from the 10 largest cohort studies, two international studies, and 28 randomised trials, supplemented by unpublished data on causes of death obtained when necessary. MAIN OUTCOME MEASURES--Excess cause specific mortality associated with low or lowered serum cholesterol concentration. RESULTS--The only cause of death attributable to low serum cholesterol concentration was haemorrhagic stroke. The excess risk was associated only with concentrations below about 5 mmol/l (relative risk 1.9, 95% confidence interval 1.4 to 2.5), affecting about 6% of people in Western populations. For noncirculatory causes of death there was a pronounced difference between cohort studies of employed men, likely to be healthy at recruitment, and cohort studies of subjects in community settings, necessarily including some with existing disease. The employed cohorts showed no excess mortality. The community cohorts showed associations between low cholesterol concentration and lung cancer, haemopoietic cancers, suicide, chronic bronchitis, and chronic liver and bowel disease; these were most satisfactorily explained by early disease or by factors that cause the disease lowering serum cholesterol concentration (depression causes suicide and lowers cholesterol concentration, for example). In the randomised trials nine deaths (from a total of 687 deaths not due to ischaemic heart disease in treated subjects) were attributed to known adverse effects of the specific treatments, but otherwise there was no evidence of an increased mortality from any cause arising from reduction in cholesterol concentration. CONCLUSIONS--There is no evidence that low or reduced serum cholesterol concentration increases mortality from any cause other than haemorrhagic stroke. This risk affects only those people with a very low concentration and even in these will be outweighed by the benefits from the low risk of ischaemic heart disease.     

Body Mass Index and All-Cause Mortality in a Large Prospective Cohort of White and Black U.S. Adults

Remaining controversies on the association between body mass index (BMI) and mortality include the effects of smoking and prevalent disease on the association, whether overweight is associated with higher mortality rates, differences in associations by race and the optimal age at which BMI predicts mortality. To assess the relative risk (RR) of mortality by BMI in Whites and Blacks among subgroups defined by smoking, prevalent disease, and age, 891,572 White and 38,119 Black men and women provided height, weight and other information when enrolled in the Cancer Prevention Study II in 1982. Over 28 years of follow-up, there were 434,400 deaths in Whites and 18,702 deaths in Blacks. Cox proportional-hazards regression was used to estimate multivariable-adjusted relative risks (RR) and 95% confidence intervals (CI). Smoking and prevalent disease status significantly modified the BMI-mortality relationship in Whites and Blacks; higher BMI was most strongly associated with higher risk of mortality among never smokers without prevalent disease. All levels of overweight and obesity were associated with a statistically significantly higher risk of mortality compared to the reference category (BMI 22.5–24.9 kg/m²), except among Black women where risk was elevated but not statistically significant in the lower end of overweight. Although absolute mortality rates were higher in Blacks than Whites within each BMI category, relative risks (RRs) were similar between race groups for both men and women (p-heterogeneity by race  = 0.20 for men and 0.23 for women). BMI was most strongly associated with mortality when reported before age 70 years. Results from this study demonstrate for the first time that the BMI-mortality relationship differs for men and women who smoke or have prevalent disease compared to healthy never-smokers. These findings further support recommendations for maintaining a BMI between 20–25 kg/m² for optimal health and longevity.     

Attributable causes of esophageal cancer incidence and mortality in china

Background

To estimate the contribution of tobacco smoking, alcohol drinking, low vegetable intake and low fruit intake to esophageal cancer mortality and incidence in China.

Methodology/Principal Findings

We calculated the proportion of esophageal cancer attributable to four known modifiable risk factors [population attributable fraction (PAF)]. Exposure data was taken from meta-analyses and large-scale national surveys of representative samples of the Chinese population. Data on relative risks were also from meta-analyses and large-scale prospective studies. Esophageal cancer mortality and incidence came from the 3^rd national death cause survey and population-based cancer registries in China. We estimated that 87,065 esophageal cancer deaths (men 67,686; women: 19,379) and 108,206 cases (men: 83,968, women: 24,238) were attributable to tobacco smoking, alcohol drinking, low vegetable intake and low fruit intake in China in 2005. About 17.9% of esophageal cancer deaths among men and 1.9% among women were attributable to tobacco smoking. About 15.2% of esophageal cancer deaths in men and 1.3% in women were caused by alcohol drinking. Low vegetable intake was responsible for 4.3% esophageal cancer deaths in men and 4.1% in women. The fraction of esophageal cancer deaths attributable to low fruit intake was 27.1% in men and 28.0% in women. Overall, 46% of esophageal cancers (51% in men and 33% in women) were attributable to these four modifiable risk factors.

Conclusions/Significance

Tobacco smoking, alcohol drinking, low vegetable intake and low fruit intake were responsible for 46% of esophageal cancer mortality and incidence in China in 2005. These findings provide useful data for developing guidelines for esophageal cancer prevention and control in China.     

Low serum cholesterol concentration and short term mortality from injuries in men and women.

OBJECTIVE--To determine whether total serum cholesterol concentration predicts mortality from injuries including suicide. DESIGN--Cohort study of men and women who had their serum cholesterol concentration measured as part of a general health survey in Värmland, Sweden in 1964 or 1965 and were followed up for an average of 20.5 years. SUBJECTS--Adults participating in health screening in 1964-5 (26,693 men and 27,692 women). The study sample was restricted to subjects aged 45-74 years during any of the 20.5 years of follow-up. MAIN OUTCOME MEASURES--Serum cholesterol concentration. Deaths from all injuries and suicides during three periods of follow up (0-6 years, 7-13 years, and 14-21 years) according to the Swedish mortality register in subjects aged 45-74. Adjustment was made for prevalent cancer (identified from the Swedish cancer register) at the time of a suicide. RESULTS--A strong negative relation between cholesterol concentration and mortality from injuries was found in men during the first seven years of follow up. The relative risk in the lowest 25% of the cholesterol distribution was 2.8 (95% confidence interval 1.52 to 4.96) compared with the top 25%. Most of the excess risk was caused by suicide with a corresponding relative risk of 4.2 (p for trend = 0.001). Correction for prevalent cancer did not change the results. Events occurring during the latter two thirds of the 20.5 years of follow up were not predicted. In women no relation between cholesterol concentration and mortality from injuries was found. CONCLUSIONS--Together with observations from intervention trials the findings support the existence of a relation between serum cholesterol concentration and suicide. The causality of such a relation is, however, not resolved.     

Influence of sex,age, body mass index,and smoking on alcohol intake and mortality.

OBJECTIVE--To examine the association between self reported alcohol intake and subsequent mortality from all causes and if the effect of alcohol intake on the risk of death is modified by sex, age, body mass index, and smoking. DESIGN--Prospective population study with baseline assessment of alcohol and tobacco consumption and body mass index, and 10-12 years'' follow up of mortality. SETTING--Copenhagen city heart study, Denmark. SUBJECTS--7234 women and 6051 men aged 30-79 years. MAIN OUTCOME MEASURE--Number and time of deaths from 1976 to 1988. RESULTS--A total of 2229 people died, 1398 being men. A U shaped curve described the relation between alcohol intake and mortality. The lowest risk was observed at one to six alcoholic beverages a week (relative risk set at 1). Abstainers had a relative risk of 1.37 (95% confidence interval 1.20 to 1.56) whereas those drinking more than 70 beverages a week had a relative risk of 2.29 (1.75 to 3.00). Among the drinkers, the risk was significantly increased only among those drinking more than 42 beverages a week. Sex, age, body mass index, and smoking did not significantly modify the risk function. The risk among heavy drinkers was slightly reduced when smoking was controlled for. The risk function was similar in the first and second period of six years of observation. CONCLUSION--Alcohol intake showed a U shaped relation to mortality with the nadir at one to six beverages a week. The risk function was not modified by sex, age, body mass index, or smoking and remained stable over 12 years.     

Do changes in cardiovascular risk factors explain changes in mortality from stroke in Finland?

OBJECTIVES--To estimate the extent to which the changes in the main cardiovascular risk factors (blood pressure, smoking, and serum cholesterol concentration) can explain the observed changes in mortality from stroke in Finland during the past 20 years. DESIGN--Predicted changes in mortality from cerebrovascular disease mortality were calculated by a proportional hazards model from data obtained in cross sectional population surveys in 1972, 1977, 1982, 1987, and 1992. Predicted changes were compared with the observed changes in mortality statistics. SETTING--North Karelia and Kuopio provinces, Finland. SUBJECTS--16,741 men and 16,389 women aged 30-59 randomly selected from the national population register, of whom 14,054 men and 14,546 women participated. MAIN OUTCOME MEASURES--Levels of risk factors and predicted and observed changes in mortality from cerebrovascular disease. RESULTS--The observed changes in diastolic blood pressure, total serum cholesterol concentration, and smoking in the population from 1972 to 1992 predicted a 44% fall in mortality from stroke in men and changes in diastolic blood pressure and smoking predicted a 34% fall in women. The observed fall in mortality from stroke was 66% in men and 60% in women. CONCLUSIONS--Two thirds of the fall in mortality from stroke in men and half in women can be explained by changes in the three main cardiovascular risk factors.     

Body weight and risk of myocardial infarction and death in the adult population of eastern Finland.

Body mass index (weight (kg) divided by height squared (m2] and its association with the risk of myocardial infarction and death from all causes were studied prospectively in a randomly selected population sample in eastern Finland aged 30-59 at outset in 1972. The study population consisted of 3786 men and 4120 women. The participation rate in the survey in 1972 was over 90%. All deaths and admissions to hospital in the sample were obtained from the National Death Certificate and Hospital Discharge Registers. During the seven years of follow up until 1978, 170 men and 52 women had acute myocardial infarction, and during the nine years up to 1980, 223 men and 92 women died. Independent of age, men with a body mass index of 28.5 or more had a significantly higher incidence of acute myocardial infarction. This effect was also independent of smoking but not independent of biological coronary risk factors--that is, serum cholesterol concentration and blood pressure. In the analysis stratified for smoking in men the body mass index total mortality curve was J shaped among non-smokers, whereas smoking entirely outweighed body mass index as a predictor of death. Body mass index did not contribute significantly to the risk of either acute myocardial infarction or death in women. It is concluded that a body mass index of around 29.0-31.0 or more is not only a marker for coronary risk factors but is also a predictor of acute myocardial infarction in men.     

Mortality in relation to consumption of alcohol: 13 years' observations on male British doctors.

OBJECTIVE--To assess the risk of death associated with various patterns of alcohol consumption. DESIGN--Prospective study of mortality in relation to alcohol drinking habits in 1978, with causes of death sought over the next 13 years (to 1991). SUBJECTS--12,321 British male doctors born between 1900 and 1930 (mean 1916) who replied to a postal questionnaire in 1978. Those written to in 1978 were the survivors of a long running prospective study of the effects of smoking that had begun in 1951 and was still continuing. RESULTS--Men were divided on the basis of their response to the 1978 questionnaire into two groups according to whether or not they had ever had any type of vascular disease, diabetes, or "life threatening disease" and into seven groups according to the amount of alcohol they drank. By 1991 almost a third had died. All statistical analyses of mortality were standardised for age, calendar year, and smoking habit. There was a U shaped relation between all cause mortality and the average amount of alcohol reportedly drunk; those who reported drinking 8-14 units of alcohol a week (corresponding to an average of one to two units a day) had the lowest risks. The causes of death were grouped into three main categories: "alcohol augmented" causes (6% of all deaths: cirrhosis, liver cancer, upper aerodigestive (mouth, oesophagus, larynx, and pharynx) cancer, alcoholism, poisoning, or injury), ischaemic heart disease (33% of all deaths), and other causes. The few deaths from alcohol augmented causes showed, at least among regular drinkers, a progressive trend, with the risk increasing with dose. In contrast, the many deaths from ischaemic heart disease showed no significant trend among regular drinkers, but there were significantly lower rates in regular drinkers than in non-drinkers. The aggregate of all other causes showed a U shaped dose-response relation similar to that for all cause mortality. Similar differences persisted irrespective of a history of previous disease, age (under 75 or 75 and older), and period of follow up (first five and last eight years). Some, but apparently not much, of the excess mortality in non-drinkers could be attributed to the inclusion among them of a small proportion of former drinkers. CONCLUSION--The consumption of alcohol appeared to reduce the risk of ischaemic heart disease, largely irrespective of amount. Among regular drinkers mortality from all causes combined increased progressively with amount drunk above 21 units a week. Among British men in middle or older age the consumption of an average of one or two units of alcohol a day is associated with significantly lower all cause mortality than is the consumption of no alcohol, or the consumption of substantial amounts. Above about three units (two American units) of alcohol a day, progressively greater levels of consumption are associated with progressively higher all cause mortality.     

Epidemiology and prevention of smoking in Tunisia: current situation and perspectives

This paper describes the trends in tobacco sales and smoking prevalence in the Tunisian population, estimates the consequences of smoking on mortality of this population, and discusses anti-tobacco actions: educational actions, legislative measures and price increases. Sales Data were collected from the Tunisia tobacco company. Smoking prevalence data from surveys, conducted by several institutes, and numbers of deaths by causes have been estimated from WHO for the year 1998. Tobacco sales increased from 4.96 g per adult per day in 1981, to 6.3 g, in 1993, then decreased widely. The proportion of smokers was 30% in 1996. 55% among men versus 5.6% among women. Among 17 to 24 years old young adults, the proportion of smokers was 29.2% in 1994 (50% among men versus 3.9%, among women). Mortality attributable to tobacco in Tunisia has been estimated to 6430 deaths in 1997 (5580 among men versus 850 among women). These deaths represent 22% of the total male deaths and 4% of the female ones. Anti-tobacco measures have been reinforced by the enactment of anti-tobacco law. Proportion of young smokers remaining elevated, it is expected that consequences of the tobacco addiction in Tunisia, in term of mortality, will be even heavier in the next two decades, if efficient anti-tobacco actions are not implemented.     

Focus: Preventive Medicine: Variation in Non-external and External Causes of Death in Peru in Relation to the COVID-19 Lockdown

Introduction: Lockdowns are designed to slow COVID-19 transmission, but they may have unanticipated relationships with other aspects of public health. Assessing the overall pattern in population health as a country implements and relaxes a lockdown is relevant, as these patterns may not necessarily be symmetric. We aimed to estimate the changing trends in cause-specific mortality in relation to the 2020 COVID-19 related lockdowns in Peru. Methods: Based on data from the Peruvian National Death Information System (SINADEF), we calculated death rates per 10 million population to assess the trends in mortality rates for non-external and external causes of death (suicides, traffic accidents, and homicides). We compared these trends to 2018-2019, before, during, and after the lockdown, stratified by sex, and adjusted by Peruvian macro-region (Lima & Callao (capital region), Coast, Highland, and Jungle). Results: Non-external deaths presented a distinctive pattern among macro-regions, with an early surge in the Jungle and a later increase in the Highland. External deaths dropped during the lockdown, however, suicides and homicides returned to previous levels in the post-lockdown period. Deaths due to traffic accidents dropped during the lockdown and returned to pre-pandemic levels by December 2020. Conclusions: We found a sudden drop in external causes of death, with suicides and homicides returning to previous levels after the lifting of the lockdown. Non-external deaths showed a differential pattern by macro-region. A close monitoring of these trends could help identify early spikes among these causes of death and take action to prevent a further increase in mortality indirectly affected by the pandemic.     

Russian mortality trends for 1991-2001: analysis by cause and region

Objectives To investigate trends in Russian mortality for 1991-2001 with particular reference to trends since the Russian economic crisis in 1998 and to geographical differences within Russia.Design Analysis of data obtained from the Russian State statistics committee for 1991-2001. All cause mortality was compared between seven federal regions. Comparison of cause specific rates was conducted for young (15-34 years) and middle aged adults (35-69 years). The number of Russian adults who died before age 70 in the period 1992-2001 and whose deaths were attributable to increased mortality was calculated.Main outcome measures Age, sex, and cause specific mortality standardised to the world population.Results Mortality increased substantially after the economic crisis in 1998, with life expectancy falling to 58.9 years among men and 71.8 years among women by 2001. Most of these fluctuations were due to changes in mortality from vascular disease and violent deaths (mainly suicides, homicides, unintentional poisoning, and traffic incidents) among young and middle aged adults. Trends were similar in all parts of Russia. An extra 2.5-3 million Russian adults died in middle age in the period 1992-2001 than would have been expected based on 1991 mortality.Conclusions Russian mortality was already high in 1991 and has increased further in the subsequent decade. Fluctuations in mortality seem to correlate strongly with underlying economic and societal factors. On an individual level, alcohol consumption is strongly implicated in being at least partially responsible for many of these trends.     

Social deprivation and premature mortality: regional comparison across England.

OBJECTIVE--To investigate the pattern and size of the relationship between social deprivation in electoral wards and premature mortality for each health region in England. DESIGN--Ecological study using 1981 census variables and data on mortality for 1981-5. SETTING--14 regional health authorities in England. MAIN OUTCOME MEASURE--Mortality under the age of 65 years from all causes, coronary heart disease, and smoking related diseases in men and women. RESULTS--Increasing deprivation was significantly associated with mortality from all causes, coronary heart disease, and smoking related diseases. The relationship was linear with no apparent threshold. Correlation coefficients were generally greater for deaths from all causes and smoking related diseases and for men compared with women. The slope of the relationship between deprivation and mortality varied among regions. Variations in mortality still existed between regions for equal levels of deprivation. CONCLUSION--Deprivation of an area and premature mortality are strongly linked. The effects of deprivation can be seen throughout the range of affluence and are not limited to the poorest areas. Current targets for reducing coronary heart disease mortality may be achievable if the mortality in poor areas can be reduced to the rates in affluent areas.     

The lipoprotein lipase S447X polymorphism and plasma lipids: interactions with APOE polymorphisms, smoking, and alcohol consumption

We studied 4,058 subjects from a representative sample of the Singapore population 1) to determine the association between the S447X polymorphism at the LPL locus and serum lipid concentration in Chinese, Malays, and Asian Indians living in Singapore and 2) to explore any interactions with apolipoprotein E (APOE) genotype, exercise, obesity, cigarette smoking, and alcohol intake. Information on obesity, lifestyle factors (including smoking, alcohol consumption, and exercise frequency), glucose tolerance, and fasting lipids was obtained. Male and female carriers of the X447 allele had lower serum triglyceride concentrations and higher HDL cholesterol (HDL-C) concentrations. The association between the X447 allele and serum HDL-C concentration was modulated by APOE genotype in males and cigarette smoking and alcohol intake in females. The effect of the X447 allele was greatest in men who carried the E4 allele and women who smoked or consumed alcohol. The X447 allele at the LPL locus is common and associated with a less atherogenic lipid profile in Asian populations. Interactions with APOE genotype, cigarette smoking, and alcohol intake reinforce the importance of examining genetic associations, such as this one, in the context of the population of interest.
