Early growth and death from cardiovascular disease in women.

OBJECTIVE--To determine whether the link suggested between growth in utero and during infancy and death from cardiovascular disease in men is also present in women. DESIGN--Follow up study of women and men whose birth weight and weight at 1 year of age had been recorded. SETTING--Hertfordshire, England. SUBJECTS--5585 women and 10,141 men born during 1911-30. MAIN OUTCOME MEASURES--Standardised mortality ratios for cardiovascular disease. RESULTS--Among women and men death rates from cardiovascular disease fell progressively between the low and high birth weights groups (chi 2 = 4.3, p = 0.04 for women, chi 2 = 8.5, p < 0.005 for men). Cardiovascular deaths in men but not women were also strongly related to weight at 1 year, falling progressively between the low and high weight groups (chi 2 = 27.5, p < 0.0001). The highest cardiovascular death rates in women were among those with below average birth weight but above average weight at 1 year. In men the highest rates were among those with below average birth weight and below average weight at 1 year. CONCLUSION--Relations between cardiovascular disease and birth weight are similar in men and women. In men cardiovascular disease is also related to weight gain in infancy.     

Mortality from cardiovascular disease among interregional migrants in England and Wales.

OBJECTIVE--To investigate the extent to which geographical variations in mortality from ischaemic heart disease and stroke in Britain are influenced by factors in early life or in adulthood. DESIGN--Longitudinal study of migrants. SUBJECTS--1% sample of residents in England and Wales born before October 1939 and enumerated at the 1971 census (the Office of Population Censuses and Surveys'' longitudinal study). MAIN OUTCOME MEASURE--18,221 deaths from ischaemic heart disease and 9899 deaths from stroke during 1971-88 were analysed by areas of residence in 1939 and 1971. These included 2928 deaths from ischaemic heart disease and 1608 deaths from stroke among individuals moving between 14 areas defined by the major conurbations and nine standard administrative regions of England and Wales. RESULTS--The southeast to northwest gradient in mortality from ischaemic heart disease was related significantly to both the 1939 area (chi 2 = 6.09, df = 1) and area in 1971 (chi 2 = 5.05, df = 1). Geographical variations in mortality from stroke were related significantly to the 1939 area (chi 2 = 4.09, df = 1) but the effect of area in 1971 was greater (chi 2 = 8.07, df = 1). The effect of 1971 area on mortality from stroke was largely due to a lower risk of death from stroke among individuals moving into Greater London compared with migrants to the rest of the South East region (chi 2 = 4.54, df = 1). CONCLUSIONS--Geographical variations in mortality from cardiovascular disease in Britain may be partly determined by genetic factors, environmental exposures, or lifestyle acquired early in life, but the risk of fatal ischaemic heart disease and stroke changes on migration between areas with differing mortality. The low risk of death from stroke associated with residence in Greater London is acquired by individuals who move there.     

The reversal of fortunes: trends in county mortality and cross-county mortality disparities in the United States

Background

Counties are the smallest unit for which mortality data are routinely available, allowing consistent and comparable long-term analysis of trends in health disparities. Average life expectancy has steadily increased in the United States but there is limited information on long-term mortality trends in the US counties This study aimed to investigate trends in county mortality and cross-county mortality disparities, including the contributions of specific diseases to county level mortality trends.

Methods and Findings

We used mortality statistics (from the National Center for Health Statistics [NCHS]) and population (from the US Census) to estimate sex-specific life expectancy for US counties for every year between 1961 and 1999. Data for analyses in subsequent years were not provided to us by the NCHS. We calculated different metrics of cross-county mortality disparity, and also grouped counties on the basis of whether their mortality changed favorably or unfavorably relative to the national average. We estimated the probability of death from specific diseases for counties with above- or below-average mortality performance. We simulated the effect of cross-county migration on each county''s life expectancy using a time-based simulation model. Between 1961 and 1999, the standard deviation (SD) of life expectancy across US counties was at its lowest in 1983, at 1.9 and 1.4 y for men and women, respectively. Cross-county life expectancy SD increased to 2.3 and 1.7 y in 1999. Between 1961 and 1983 no counties had a statistically significant increase in mortality; the major cause of mortality decline for both sexes was reduction in cardiovascular mortality. From 1983 to 1999, life expectancy declined significantly in 11 counties for men (by 1.3 y) and in 180 counties for women (by 1.3 y); another 48 (men) and 783 (women) counties had nonsignificant life expectancy decline. Life expectancy decline in both sexes was caused by increased mortality from lung cancer, chronic obstructive pulmonary disease (COPD), diabetes, and a range of other noncommunicable diseases, which were no longer compensated for by the decline in cardiovascular mortality. Higher HIV/AIDS and homicide deaths also contributed substantially to life expectancy decline for men, but not for women. Alternative specifications of the effects of migration showed that the rise in cross-county life expectancy SD was unlikely to be caused by migration.

Conclusions

There was a steady increase in mortality inequality across the US counties between 1983 and 1999, resulting from stagnation or increase in mortality among the worst-off segment of the population. Female mortality increased in a large number of counties, primarily because of chronic diseases related to smoking, overweight and obesity, and high blood pressure.     

Long term effects of hysterectomy on mortality: nested cohort study

Objectives To investigate the long term risk (mean > 20 years) of death from all causes, cardiovascular disease, and cancer in women who had or had not had a hysterectomy.Design Nested cohort study.Setting Royal College of General Practitioners'' oral contraception study.Participants 7410 women (3705 flagged at the NHS central registries for cancer and death who had a hysterectomy during the oral contraception study and 3705 who were flagged but did not have the operation).Main outcome measures Mortality from all causes, cardiovascular disease, and cancer.Results 623 (8.4%) women had died by the end of follow-up (308 in the hysterectomy group and 315 in the non-hysterectomy group). Older women who had had a hysterectomy had a 6% reduced risk of death compared with women of a similar age who did not have the operation (adjusted hazard ratio 0.94, 95% confidence interval 0.75 to 1.18). Compared with young women who did not have a hysterectomy those who were younger at hysterectomy had an adjusted hazard ratio for all cause mortality of 0.82 (0.65 to 1.03). Hysterectomy was not associated with a significantly altered risk of mortality from cardiovascular disease or cancer regardless of age.Conclusion Hysterectomy did not increase the risk of death in the medium to long term.     

Regression analysis of recent changes in cardiovascular morbidity and mortality in The Netherlands.

OBJECTIVES: To test whether recent declines in mortality from coronary heart disease were associated with increased mortality from other cardiovascular diseases. DESIGN: Poisson regression analysis of national data on causes of death and hospital discharges. SETTING AND SUBJECTS: Population of the Netherlands, 1969-93. MAIN OUTCOME MEASURES: Annual changes in mortality from coronary heart disease, stroke, and other cardiovascular diseases and annual changes in hospital discharge rates for acute coronary events, stroke, and congestive heart failures. RESULTS: Patterns of cardiovascular mortality changed abruptly in 1987-93. Annual decline in mortality from coronary heart disease increased sharply for women and men: from -1.9% (95% confidence interval -2.2% to -1.6%) and -1.7% (-1.9% to -1.4%) respectively in 1979-86 to -3.1% (-3.5% to -2.6%) and -4.2% (-4.6% to -3.9%) in 1987-93. The longstanding decline in mortality from stroke levelled off: from annual change of -3.3% (-3.7% to -2.8%) and -3.2% (-3.7% to -2.8%) in 1979-86 to -0.1% (-0.7% to 0.4%) and -1.1% (-1.7% to -0.5%) in 1987-93. Mortality from other cardiovascular diseases, however, started to increase: from -2.0% (-2.4% to -1.6%) and -0.2% (-0.5% to 0.2%) in 1979-86 to 1.5% (1.0% to 2.0%) and 1.9% (1.5% to 2.3%) in 1987-93. Hospital discharge rates for acute coronary heart disease, congestive heart failure, and stroke increased during 1980-6. During 1987-93 discharge rates for stroke and coronary heart disease stabilised but rates for congestive heart failure increased. CONCLUSION: Improved management of coronary heart disease seems to have reduced mortality, but some of the gains are lost to deaths from stroke and other cardiovascular diseases. The increasing numbers of patients with coronary heart disease who survive will increase demands on health services for long term care.     

Cardiovascular risk factors in British children from towns with widely differing adult cardiovascular mortality.

OBJECTIVE--To examine whether cardiovascular risk factors differ in children from towns in England and Wales with widely differing adult cardiovascular death rates. DESIGN--School based survey conducted during 1994 in 10 towns, five with exceptionally high adult cardiovascular mortality (standardised mortality ratio 131-143) and five with exceptionally low adult cardiovascular mortality (64-75). Towns were surveyed in high-low pairs. SUBJECTS--3415 white children aged 8-11 years with physical measurements (response rate 75%), including 1287 with blood samples (response rate 64%), of whom 515 had blood samples taken 30 minutes after a glucose load. RESULTS--Children in towns with high cardiovascular mortality were on average shorter than those in towns with low mortality (mean difference 1.2 cm; 95% confidence interval 0.3 to 2.1 cm; P = 0.02) and had a higher ponderal index (0.34 kg/m3; 0.16 to 0.52 kg/m3; P = 0.006). Mean systolic pressure was higher in high mortality towns, particularly after adjustment for height (2.0 mm Hg; 0.8 to 3.2 mm Hg; P = 0.009). Mean waist:hip ratio, total cholesterol concentration, and 30 minute post-load glucose measurements were similar in high and low mortality towns. The differences in height and blood pressure between high and low mortality towns were unaffected by standardisation for birth weight. CONCLUSIONS--The differences in height, ponderal index, and blood pressure between towns with high and low cardiovascular mortality, if persistent, may have important future public health implications. Their independence of birth weight suggests that the childhood environment rather than the intrauterine environment is involved in their development.     

Socioeconomic gradient in morbidity and mortality in people with diabetes: cohort study findings from the Whitehall Study and the WHO Multinational Study of Vascular Disease in Diabetes.

OBJECTIVE: To assess whether the inverse socioeconomic mortality gradient observed in the general population persists in diabetic people. DESIGN: The Whitehall cohort study and the London cohort of the WHO multinational study of vascular disease in diabetes. SETTING: London. SUBJECTS: 17,264 male civil servants (17,046 without diabetes, 218 with diabetes) aged 40-64 examined in 1967-9, and 300 people with diabetes aged 35-55 from London clinics examined in 1975-7. Both cohorts were followed up until January 1995. MAIN OUTCOME MEASURES: Mortality from all causes, cardiovascular disease, and ischaemic heart disease. RESULTS: In both cohorts people in the lower social groups were older, had higher blood pressure, and were more likely to smoke. In the Whitehall study, the prevalence of heart disease was higher in the lowest social group compared with the highest group, by 6% among non-diabetic people (P = 0.0001) and by 14% among diabetic subjects (P = 0.02). In the WHO study proteinuria was more common in the lowest social group compared with the highest (27% v 15%, P = 0.01), as was retinopathy (54% v 48%, P = 0.5). There was a clear socioeconomic gradient in all cause mortality in both cohorts, with death rates being about twice as high in the lowest compared with the highest social groups. In the Whitehall study this gradient was similar in both diabetic and non-diabetic subjects, and it persisted for mortality from cardiovascular disease and from ischaemic heart disease. About half of the increased risk of death in the lowest social group was accounted for by blood pressure and smoking. CONCLUSIONS: We confirm the existence of an inverse socioeconomic mortality gradient in diabetic people and suggest that this is largely due to conventional cardiovascular risk factors.     

Inequalities in women's health: looking at mortality differentials using an alternative approach

Data obtained from follow up of the 1971 census sample in the Office of Population Censuses and Surveys longitudinal study of England and Wales were used to look at women''s mortality differentials at ages 15-59. Women were grouped by combining information on marital state, own occupation, husband''s occupation (if married), economic activity, and indicators of household wealth (housing tenure and access to a car). Large groups were found with considerable differences in mortality. High mortality was associated with working in manual occupations and living in rented housing with no car in the household. In contrast, low mortality was associated with non-manual occupations and living in owner occupied housing with a car. Among married housewives and single women these extreme groups contributed 44% of expected deaths, the disadvantaged group experiencing death rates two and a half times that of the advantaged group. Smaller differences were found among married women with an occupational class.These findings are further evidence of the “health divide” in England and Wales and show that accurately to reflect the relation between a woman''s life circumstances and mortality it is necessary to utilise other measures than those based solely on occupation.     

A demographic analysis of skeletons from the Larson site (39WW2) Walworth County,South Dakota: Vital statistics

A life table methodology was used for paleodemographic analysis of skeletons from the Larson site (39WW2), an Arikara village and cemetery dated to circa A.D. 1750–1785. Vital statistics on mortality, survivorship, age-specific probability of death, life expectancy and crude mortality rate were derived from skeletal data. The population had an extremely high infant mortality rate and high rates of childhood mortality. The lowest probability of death was for adolescents. Mortality increased for young adults, ages 15–19. This increase was especially marked for females, the actual peak of adult female mortality was during ages 15–19. A second mode in the female mortality curve occurred at ages 35–39. The greatest percentage of male deaths was observed in the fourth decade, ages 30–34. Only 4.0% of the population attained the age of 50. The population crude death rate was 76 per thousand per year. This estimate, although high, is congruent with archaeological and historical sources which report a rapid Arikara population decline during the Post-Contact period. Causes of specific deaths appear to be linked to childbirth (affecting mother and infant), starvation, diseases especially tuberculosis, and intertribal warfare.     

Trends in perinatal mortality attributed to congenital malformations in England and Wales during 1974-81: a study of the variations among regional health authority areas

Analysis of perinatal mortality attributed to congenital malformations in England and Wales, using data from birth and death registration over the years 1974-81 showed significant declines in England and Wales as a whole and in the individual Regional Health Authority (RHA) areas. A greater decrease in death rate from congenital malformations, particularly central nervous system malformations, was seen among stillbirths than among early neonatal deaths. There were marked regional differences in perinatal mortality due to central nervous system malformations over the period but not in cardiovascular system malformations or in other malformations. The highest mortality rates due to central nervous system malformations occurred in the North, North-West, West and South-West of England and in Wales, and the lowest rates in the South and South-East. The larger percentage reductions in the mortality rates were found in most of the regions which had had the highest rates. Possible explanations for the decline in regional rates are suggested.     

Outlook for survivors of childhood in sub-Saharan Africa: adult mortality in Tanzania. Adult Morbidity and Mortality Project.

OBJECTIVE--To measure age and sex specific mortality in adults (15-59 years) in one urban and two rural areas of Tanzania. DESIGN--Reporting of all deaths occurring between 1 June 1992 and 31 May 1995. SETTING--Eight branches in Dar es Salaam (Tanzania''s largest city), 59 villages in Morogoro rural district (a poor rural area), and 47 villages in Hai district (a more prosperous rural area). SUBJECTS--40,304 adults in Dar es Salaam, 69,964 in Hai, 50,465 in Morogoro rural. MAIN OUTCOME MEASURES--Mortality and probability of death between 15 and 59 years of age (45Q15). RESULTS--During the three year observation period a total of 4929 deaths were recorded in adults aged 15-59 years in all areas. Crude mortalities ranged from 6.1/1000/year for women in Hai to 15.9/1000/year for men in Morogoro rural. Age specific mortalities were up to 43 times higher than rates in England and Wales. Rates were higher in men at all ages in the two rural areas except in the age group 25 to 29 years in Hai and 20 to 34 years in Morogoro rural. In Dar es Salaam rates in men were higher only in the 40 to 59 year age group. The probability of death before age 60 of a 15 year old man (45Q15) was 47% in Dar es Salaam, 37% in Hai, and 58% in Morogoro; for women these figures were 45%, 26%, and 48%, respectively. (The average 45Q15s for men and women in established market economies are 15% and 7%, respectively.) CONCLUSION--Survivors of childhood in Tanzania continue to show high rates of mortality throughout adult life. As the health of adults is essential for the wellbeing of young and old there is an urgent need to develop policies that deal with the causes of adult mortality.     

Patterns of mortality in second generation Irish living in England and Wales: longitudinal study.

OBJECTIVE--To examine the mortality of second generation Irish living in England and Wales. DESIGN--Longitudinal study of 1% of the population of England and Wales (longitudinal study by the Office of Population Censuses and Surveys (now the Office for National Statistics)) followed up from 1971 to 1989. SUBJECTS--3075 men and 3233 women aged 15 and over in 1971. MAIN OUTCOME MEASURES--Age and sex specific standardised mortality ratios for all causes, cancers, coronary heart disease, cerebrovascular diseases, respiratory diseases, and injuries and poisonings. Deaths were also analysed by socioeconomic indicators. RESULTS--786 deaths were traced to men and 762 to women. At working ages (men, aged 15-64; women, 15-59) the mortality of men (standardised mortality ratio 126) and women (129) was significantly higher than that of all men and all women. At ages 15-44, relative disadvantages were even greater both for men (145) and for women (164). Mortality was raised for most major causes of death. Significant excess mortality from cancers was seen for men of working age (132) and for women aged 60 and over (122). At working ages mortality of the second generation Irish in every social class and in the categories of car access and housing tenure was higher than that of all men and all women in the corresponding categories. Adjusting for these socioeconomic indicators did not explain the excess mortality. CONCLUSION--Mortality of second generation Irish men and women was higher than that of all men and all women and for most major causes of death. While socioeconomic factors remain important, cultural and lifestyle factors are likely to contribute to this adverse mortality.     

The relation of small head circumference and thinness at birth to death from cardiovascular disease in adult life.

OBJECTIVE--To determine how fetal growth is related to death from cardiovascular disease in adult life. DESIGN--A follow up study of men born during 1907-24 whose birth weights, head circumferences, and other body measurements were recorded at birth. SETTING--Sheffield, England. SUBJECTS--1586 Men born in the Jessop Hospital. MAIN OUTCOME MEASURE--Death from cardiovascular disease. RESULTS--Standardised mortality ratios for cardiovascular disease fell from 119 in men who weighed 5.5 pounds (2495 g) or less at birth to 74 in men who weighed more than 8.5 pounds (3856 g). The fall was significant for premature cardiovascular deaths up to 65 years of age (chi 2 = 5.0, p = 0.02). Standardised mortality ratios also fell with increasing head circumference (chi 2 = 4.6, p = 0.03) and increasing ponderal index (weight/length3) (chi 2 = 3.8, p = 0.05; for premature deaths chi 2 = 6.0, p = 0.01). They were not related to the duration of gestation. Among men for whom the ratio of placental weight to birth weight was in the highest fifths the standardised mortality ratio was 137. CONCLUSION--These findings show that reduced fetal growth is followed by increased mortality from cardiovascular disease. They suggest that reduction in growth begins early in gestation. They are further evidence that cardiovascular disease originates through programming of the body''s structure, physiology, and metabolism by the environment during fetal life. Maternal nutrition may have an important influence on programming.     

Growth in utero,blood pressure in childhood and adult life,and mortality from cardiovascular disease.

In national samples of 9921 10 year olds and 3259 adults in Britain systolic blood pressure was inversely related to birth weight. The association was independent of gestational age and may therefore be attributed to reduced fetal growth. This suggests that the intrauterine environment influences blood pressure during adult life. It is further evidence that the geographical differences in average blood pressure and mortality from cardiovascular disease in Britain partly reflect past differences in the intrauterine environment. Within England and Wales 10 year olds living in areas with high cardiovascular mortality were shorter and had higher resting pulse rates than those living in other areas. Their mothers were also shorter and had higher diastolic blood pressures. This suggests that there are persisting geographical differences in the childhood environment that predispose to differences in cardiovascular mortality.     

Mother's weight in pregnancy and coronary heart disease in a cohort of Finnish men: follow up study.

OBJECTIVE: To determine whether restricted growth in utero is associated with an increased risk of coronary heart disease are among men in Finland, where rates of the disease are among the highest in the world. DESIGN: Follow up study. SETTING: Helsinki, Finland. SUBJECTS: 3302 men born in Helsinki University Central Hospital during 1924-33 who went to school in the city of Helsinki and were resident in Finalnd in 1971. MAIN OUTCOME MEASURES: Standardised mortality ratios for coronary heart disease. RESULTS: Men who were thin at birth, with low placental weight, had high death rates from coronary heart disease. Men whose mothers had a high body mass index in pregnancy also had high death rates. In a multivariate analysis the hazard ratio for coronary heart disease was 1.37 (95% confidence interval 1.20 to 1.57) (P < 0.0001) for every standard deviation decrease in ponderal index at birth and 1.24 (1.10 to 1.39) (P = 0.0004) for every standard deviation increase in mother''s body mass index. The effect of mother''s body mass index was restricted to mothers of below average stature. CONCLUSION: These findings suggest a new explanation for the epidemics of coronary heart disease that accompany Westernisation. Chronically malnourished women are short and light and their babies tend to be thin. The immediate effect of improved nutrition is that women become fat, which seems to increase the risk of coronary heart disease in the next generation. With continued improvements in nutrition, women become taller and heavier; their babies are adequately nourished; and maternal fatness no longer increases the risk of coronary heart disease, which therefore declines.     

Mortality in relation to tar yield of cigarettes: a prospective study of four cohorts.

OBJECTIVE--To investigate relation between tar yield of manufactured cigarettes and mortality from smoking related diseases. DESIGN--Prospective epidemiological study of four cohorts of men studied between 1967 and 1982. SETTING--Combined data from British United Provident Association (BUPA) study (London), Whitehall study (London), Paisley-Renfrew study (Scotland), and United Kingdom heart disease prevention project (England and Wales). SUBJECTS--Of the 56,255 men aged over 35 who were included in the studies, 2742 deaths occurred among 12,400 smokers. Average follow up was 13 years. MAIN OUTCOME MEASURES--Relative mortality from smoking related diseases according to tar yields of cigarettes smoked. RESULTS--Age adjusted mortality from smoking related diseases in smokers of filter cigarettes was 9% lower (95% confidence interval 1% to 17%) than in smokers related diseases consistently decreased with decreasing tar yield. Relative mortality in cigarette smokers for a 15 mg decrease in tar yield per cigarette was 0.75 (0.52 to 1.09) for lung cancer, 0.77 (0.61 to 0.97) for coronary heart disease, 0.86 (0.50 to 1.50) for stroke, 0.78 (0.40 to 1.48) for chronic obstructive lung diseases, 0.78 (0.65 to 0.93) for these smoking related diseases combined, and 0.77 (0.65 to 0.90) for all smoking related diseases. CONCLUSION--About a quarter of deaths from lung cancer, coronary heart disease, and possibly other smoking related diseases would have been avoided by lowering tar yield from 30 mg per cigarette to 15 mg. Reducing cigarette tar yields in Britain has had a modest effect in reducing smoking related mortality.     

Mortality among oral contraceptive users: 20 year follow up of women in a cohort study.

OBJECTIVE--To see whether the use of oral contraceptives influences mortality. DESIGN--Non-randomised cohort study of 17,032 women followed up on an annual basis for an average of nearly 16 years. SETTING--17 Family planning clinics in England and Scotland. SUBJECTS--Women recruited during 1968-74. At the time of recruitment each woman was aged 25-39, married, a white British subject, willing to participate, and either a current user of oral contraceptives or a current user of a diaphragm or intrauterine device (without previous exposure to the pill). MAIN OUTCOME MEASURES--Overall mortality and cause specific mortality. RESULTS--238 Deaths occurred during the follow up period. The main analyses concerned women entering the study while using either oral contraceptives or a diaphragm or intrauterine device. The overall relative risk of death in the oral contraceptive users was 0.9 (95% confidence interval 0.7 to 1.2). Though the numbers of deaths were small in most individual disease categories, the trends observed were generally consistent with findings in other reports. Thus the relative risk of death in the oral contraceptive users was 4.9 (95% confidence interval 0.7 to 230) for cancer of the cervix, 3.3 (95% confidence interval 0.9 to 17.9) for ischaemic heart disease, and 0.4 (95% confidence interval 0.1 to 1.2) for ovarian cancer. There was a linear trend in the death rates from cervical cancer and ovarian cancer (in opposite directions) with total duration of oral contraceptive use. Death rates from breast cancer (relative risk 0.9; 95% confidence interval 0.5 to 1.4) and suicide and probable suicide (relative risk 1.1; 95% confidence interval 0.3 to 3.6) were much the same in the two contraceptive groups. In 1981 the relative risk of death in oral contraceptive users from circulatory diseases as a group was reported to be 4.2 (95% confidence interval 2.3 to 7.7) in the Royal College of General Practitioners oral contraception study. The corresponding relative risk in this study was only 1.5 (95% confidence interval 0.7 to 3.0). CONCLUSIONS--These findings contain no significant evidence of any overall effect of oral contraceptive use on mortality. None the less, only small numbers of deaths occurred during the study period and a significant adverse (or beneficial) overall effect might emerge in the future. Interestingly, the mortality from circulatory disease associated with oral contraceptive use was substantially less than that found in the Royal College of General Practitioners study.     

Mortality of bereavement.

The death rate of a group of 87 widowers and 279 widows was followed for two years from the death of their spouses. The life tables for England and Wales 1970-2 indicated that the expected number of deaths would be 6 men and 11 women. The actual numbers (9 men and 11 women, 5.5%) were not significantly different, though there were more widowers'' deaths during the first six months of bereavement. There was no significantly greater mortality among those whose spouses had died in hospital; but when this had occurred the health of the second spouse was likely to have been poorer than that of those whose spouses had died at home.     

Coffee consumption and death from coronary heart disease in middle aged Norwegian men and women.

OBJECTIVE--To study the association between number of cups of coffee consumed per day and coronary death when taking other major coronary risk factors into account. DESIGN--Men and women attending screening and followed up for a mean of 6.4 years. SETTING--Cardiovascular survey performed by ambulatory teams from the National Health Screening Service in Norway. PARTICIPANTS--All middle aged people in three counties: 19,398 men and 19,166 women aged 35-54 years who reported neither cardiovascular disease or diabetes nor symptoms of angina pectoris or intermittent claudication. MAIN OUTCOME MEASURE--Predictive value of number of cups of coffee consumed per day. RESULTS--At initial screening total serum cholesterol concentration, high density lipoprotein cholesterol concentration, blood pressure, height, and weight were measured and self reported information about smoking history, physical activity, and coffee drinking habits was recorded. Altogether 168 men and 16 women died of coronary heart disease during follow up. Mean cholesterol concentrations for men and women were almost identical and increased from the lowest to highest coffee consumption group (13.1% and 10.9% respectively). With the proportional hazards model and adjustment for age, total serum and high density lipoprotein cholesterol concentrations, systolic blood pressure, and number of cigarettes per day the coefficient for coffee corresponded to a relative risk between nine or more cups of coffee and less than one cup of 2.2 (95% confidence interval 1.1 to 4.5) for men and 5.1 (0.4 to 60.3) for women. For men the relative risk varied among the three counties. CONCLUSIONS--Coffee may affect mortality from coronary heart disease over and above its effect in raising cholesterol concentrations.
