This study examined the differences in mortality rate among the three ethnic groups aged 35 to 69: 1) Japanese living in Kawasaki city, 2) Koreans living in Kawasaki city, 3) Koreans living in Korea. Three different measures were used for analysis: 1) mortality rate by sex and age, 2) Mantel-Haenszel Rate Ratio (MHRR), 3) Standardized Proportional Mortality Ratio (SPMR). Major findings were as follows: 1) In terms of mortality rate by sex and age, Koreans in both Kawasaki and Korea showed higher mortality rates than Japanese in Kawasaki for both sexes and for all of the age categories. Koreans living in Kawasaki and Koreans living in Korea showed nearly identical levels of mortality rate for both sexes and for all of the age categories. 2) Calculation of MHRR utilizing a mortality rate for Japanese living in Kawasaki as 1 yielded the following: For all causes of death, MHRR of Korean males living in Kawasaki aged 35 to 59 was 2.59, and 2.37 for ages 60 to 69. For females MHRR for those age groups were 1.91 and 2.06 respectively. All of these MHRRs were statistically significantly high (p less than 0.05). 3) Among the causes for the high MHRR for Korean males living in Kawasaki aged 35 to 59 compared in Japanese living in Kawasaki were the following: all Malignant neoplasms (ICD 9, 140-208), Malignant neoplasm of liver (155), Hypertensive disease (401-405), Ischemic heart disease (410-414), Pneumonia (480-486), Liver Cirrhosis (571). For males aged 60 to 69, causes were Tuberculosis (010-018), all Malignant neoplasms, Malignant neoplasm of liver, Ischemic heart disease, Disease of the pulmonary circulation and other forms of heart disease (415-429), Cerebrovascular disease (430-438), and Liver Cirrhosis. In the case of females, Tuberculosis, Disease of the pulmonary circulation and other forms of heart disease, Malignant neoplasm of trachea, bronchus and lung were causes for high MHRR for Koreans in Kawasaki aged 35 to 59. All Malignant neoplasms, Malignant neoplasm of liver, Malignant neoplasm of trachea, bronchus and lung, Accidental causes of death except motor vehicle accidents (E800-807, E826-848, E850-949) were causes for females aged 60 to 69. 4) The mortality rates for ages 35 to 69 for both sexes are similar for both Koreans living in Kawasaki and in Korea.(ABSTRACT TRUNCATED AT 400 WORDS)

The complications of surgical treatment for lumbar disc herniation (LDH) are important to know, but hard to measure because of their low incidence and varied pattern. Using data from the National Hospital Discharge Survey, which codes discharges and procedures according to the ICD-9-CM, we assessed acute complication rates for 3,289 surgically treated LDH patients and 4,025 nonoperative LDH patients, identifying complications from codiagnoses. The complication rates were significantly correlated with the postoperative length of stay and with the risk factors of obesity, hypertension, and diabetes. We found fewer instances of thrombophlebitis (0.3/1,000) and slightly lower mortality (0.9/1,000) than previously reported. Although the frequency of the cauda equina syndrome in the literature approximates our findings of 5/1,000, our data did not allow correction for the fraction of preexistent cauda equina syndromes. Our any-complication-rate is 3.7%. Even though LDH surgery is relatively safe, its complications should not be overlooked.

This paper presents the results of an ecologic study of the trends of ischemic heart diseases (IHD) (ICD 9th 410-414) from 1950 to 1985 in Mexico. The mortality rates area strongly related with age and sex. Among those aged 30 to 59 years old, the male-female ratio (MFR) was 2.5 whereas in those aged 60 or more the ratio was 1.2. The mortality rates for IHD increase over time, particularly when converted in logarithms (r = 0.89). There were important differences in the regional mortality patterns by age and gender. Among males the northern region showed a mortality risk 2.5 times higher than the southern region; this risk increases (3.0) in those older than 60 years old. The increasing risk modifiable risk factors such as smoking, cholesterol and hypertension.

There has been recent interest in trying to understand the way demographic changes and population structure affect disease rates in the Unites States. We analysed mortality data for 1968 to 1986 to examine how ageing and a changing population structure have affected hypertension mortality rates in the United States. Multiple-cause-of-death data were used with census projections to estimate age-adjusted, reported-prevalence-at-death rates for hypertension. For the period 1970 to 1986, we found considerable geographic diversity, including an eightfold difference in the range of hypertension mortality by state (from 11.4 in Hawaii to 82.3 in the District of Columbia). Substantial differences appeared in age-adjusted rates by race; an average twofold excess among blacks was observed throughout the period. The largest race difference in 1986 was observed in Florida, where the reported-prevalence-at-death rate was 3.2 times greater among blacks (112.2 per 100,000) than among whites (34.7 per 100,000). When we allow for discontinuities in coding between ICD-8 and ICD-9, the states will appear to be relatively stable with regard to both age-adjusted rate and relative rank. Age-adjusted, reported-prevalence-at-death rates for blacks also show geographic variability and suggest that factors other than genetics play an important role in the contribution of hypertension to mortality in the United States.

Over 8000 patients with cerebral thrombosis (ICD-8 number 433) hospitalised between 1970 and 1980 were surveyed retrospectively for outcome and additional diseases. The case-fatality rates and long-term prognosis of the patients were strongly affected by age, and the number of patients requiring permanent hospital care rose sharply with increasing age. The case-fatality rates in the different age groups were as follows: under 50 years 6%, 50-64 years 16%, 65-74 years 32%, 75-84 years 48% and over 85 years 66%. The cumulative survival rates at 1 and 5 years were as follows: under 50 years 54 and 46%, 50-64 years and 38%, 65-74 years 60 and 20% and over 75 years 45 and 10%. Clinical manifest coronary heart disease clearly affected the prognosis of patients under 75 years, but the impact diminished with rising age. Although hypertension led to an earlier onset of ischemic stroke, it did not significantly influence the survival prognosis. In patients over 75 years additional diseases, e.g. diabetes, had no significant effect on case-fatality or long-term prognosis underlining the malignant nature of cerebral thrombosis itself.

The prevalence, reversibility, and mortality of secondary hypertension among 3783 patients with moderately severe nonmalignant hypertension attending the Glasgow (Scotland) Blood Pressure Clinic were assessed. Underlying causes of hypertension were found in 297 patients (7.9%). Eighty-seven patients (2.3%) were considered to have a potentially reversible cause for their hypertension, including the oral contraceptive pill (38 patients), renovascular disease (27 patients), and primary hyperaldosteronism (ten patients), but of these only 33 patients (0.9% of total clinic population) were cured by specific intervention. Two hundred ten patients (5.6%) had irreversible renal parenchymal disease and significantly higher mortality than men and women with other causes of hypertension. Excess deaths in the renal group were attributed to renal failure (International Classification of Diseases [ICD] 580 to 589) and vascular causes (ICD 390 to 458) but not to cancer (ICD 140 to 208; 235 to 239) or other nonvascular disease. These results suggest that investigation of hypertension for an underlying cause will reveal a small number of patients with treatable disorders, of whom only a few will be cured by specific intervention, and a moderate number with irreversible disease who are at high risk of myocardial infarction and stroke.

A morbidity survey in the Falkland Islands, conducted in 1979, showed that Falkland Islands men had a lower prevalence of hypertension than their counterparts in the United Kingdon. Such a difference was not found in women.As a migrant population, Falkland Islanders are unusual in that they moved from a developed society to a more traditional setting. In men, but not in women, the change in environment led to a greater proportion of the population engaging in a high level of habitual physical activity and to a low prevalence of obesity.These findings (based on ICD codes rather than BP measurements) are consistent with the hypothesis that such a change in lifestyle may have resulted in the lower population prevalence of hypertension observed in the morbidity survey, and the implications could be important for public health.

Although the relation between serum total cholesterol and coronary heart disease is well established, the relation with mortality from non-coronary disease is controversial. Inverse relations of serum cholesterol with hemorrhagic stroke and cancer have stimulated the examination of cholesterol-non-coronary mortality associations. The population surveyed is 12,187 men and women aged 40-69 years living in Yao City, a suburb of Osaka, who undertook baseline examinations between 1975 and 1984 and had no history of stroke and coronary heart disease at baseline. The subjects were followed on average 8.9 years until the end of 1988 using systematic mortality surveillance. During the follow-up, there were 343 deaths, comprising 170 cancer deaths (International Classification of Death 9th edition: ICD-9, 140-239), 21 coronary heart disease deaths (ICD-9, 410-414), 67 other cardiovascular deaths (ICD-9, 390-458 excluding 410-414), and 85 non-cardiovascular, non-cancer deaths. There was a significant inverse association of serum cholesterol with total and cancer mortality for men, and no significant association for women. The cholesterol-disease association, although not significant, was positive for coronary heart disease and other cardiovascular disease deaths, and inverse for non-cardiovascular, non-cancer deaths in both sexes. The inverse association of serum cholesterol with total and cancer mortality for men remained significant after controlling for age, job classification, hypertension category, usual alcohol intake, cigarette smoking, and relative weight index.(ABSTRACT TRUNCATED AT 250 WORDS)

The relationship between occupational exposures and the risk of pregnancy-induced hypertension (PIH) was investigated in a cohort of 5,605 enlisted active duty military women who gave birth during a 2-year period of time. A panel of experts, unaware of disease status, classified the women's job titles as "high," "medium," or "low" for a variety of occupational exposures. PIH was identified through hospital discharge ICD-9 diagnosis codes. Nulliparas were found to have a significantly increased risk ratio (RR) for PIH (RR = 2.3) compared with parous women. Nulliparas employed in jobs involving high levels of physical activity were at significantly decreased risk of PIH compared to nulliparas working at low levels of physical activity (construction craftsmen, RR = 0.37; unskilled laborers RR = 0.71). Occupational exposure to hazardous chemicals was not related to risk of PIH. Although the study results are limited by aggregate exposure classification, they suggest no adverse influence of occupational exertion and a possible beneficial role among nulliparas.

In the evaluation of a hypertension treatment program, the end-point surveillance included incidence of acute myocardial infarction and acute stroke identified from hospital in-patient registers and the national mortality register. To ascertain the validity, in-patient records containing the ICD-codes 410-411 and 430-438 were validated. First event of acute myocardial infarction and acute stroke suggested in the in-patient register could be confirmed in 96% and 94%, respectively. In-patient diagnoses of suspected acute myocardial infarction or other acute or subacute ischemic heart diseases, transient ischemic attack and unspecified heart diseases, transient ischemic attack and unspecified cerebrovascular disease revealed high proportions of what in fact turned out to be definite events (11%, 24% and 53% respectively). It is concluded that disease ascertainment for this cohort study claims validation of register data with hospital records.
