Comparison of the associations of BMI and measures of regional adiposity with coronary heart disease, diabetes and all cause mortality
Objective: To compare magnitudes of association of BMI and measures of regional adiposity with coronary heart disease, diabetes and all-cause mortality. Design: 2 prospective cohort and 2 cross sectional studies. Participants: Members of 4 UK cohorts aged >45 years: 3937 women from the British Women's Heart and Health Study (BWHHS), 2367 and 1950 men from phases 1 and 3 of the Caerphilly Prospective Study (CaPS), 403 men and women from Boyd Orr, …
Diagnosis of past history of myocardial infarction in epidemiological studies
In epidemiological studies the diagnosis of a past history of myocardial infarction is made from the answer to a single question: "Have you ever had a severe pain across the front of your chest lasting for half an hour or more?" Two additional questions, which form an optional part of the London School of Hygiene and Tropical Medicine chest pain questionnaire, were used in two large community studies, with other information to determine the likel…
Associations of alcohol consumption with plasma high density lipoprotein cholesterol and its major subfractions
In surveys of 4860 middle-aged men in Caerphilly (South Wales) and Speedwell (Bristol) alcohol consumption has been related to high density lipoprotein (HDL) cholesterol and its major subfractions, HDL2 and HDL3, measured in a single fasting blood sample. The results confirm that high density lipoprotein cholesterol concentration increases as the amount of alcohol regularly consumed increases. The relationship appears to be linear and is independ…
Type A behaviour and prevalent heart disease in the Caerphilly study
Type A behaviour was assessed by modified Framingham scale in a total sample of 1956 employed men in the Caerphilly study. Prevalent heart disease was measured by cardiovascular questionnaire to obtain evidence of myocardial infarction and angina, and by electrocardiogram (ECG) for evidence of ischaemia. Type A was inversely related to age and systolic blood pressure and was positively related to social class and height. It was not related to ser…
Diet, alcohol, body mass, and social factors in relation to blood pressure
Data for 387 men who had completed seven-day weighed dietary records as part of the Caerphilly Heart Study were examined for relations of alcohol, diet, body mass index (BMI), and other variables to blood pressure. These included age, smoking, exercise, and social class. For men not on antihypertensive treatment (n = 356) regression analysis showed that age (p less than 0.001), BMI (p less than 0.05), and alcohol intake (p less than 0.01) were si…
Heart rate, employment status, and prevalent ischaemic heart disease confound relation between cereal fibre intake and blood pressure
Cross sectional data from a survey of 2512 men aged 45-49 years were used to examine the confounding effects of heart rate, employment, and ischaemic heart disease (IHD) on the relation between cereal fibre intake and blood pressure. Daily cereal fibre intake (g/day) was associated with systolic pressure (r = -0.053, p less than 0.01), diastolic pressure (r = -0.057, p less than 0.01), and heart rate (r = -0.071, p less than 0.01). The associatio…
Determinants of plasma lipoproteins and coagulation factors in men from Caerphilly, South Wales
Dietary, social, and constitutional determinants of plasma concentrations of some major risk factors for ischaemic heart disease were investigated in a cross sectional study among 711 men from the general population aged 30-69. For high density lipoprotein cholesterol (HDL-C) six variables were significantly associated with plasma concentrations, and these variables explained 12.6% of the variance. For low density lipoprotein cholesterol (LDL-C),…
Determinants of high density lipoprotein and total cholesterol in women
An epidemiological study was carried out among a random sample of women aged 18 to 69 years to examine possible determinants of plasma high density lipoprotein and total cholesterol (HDL-C and T-C). In a multiple regression analysis consumption of alcohol, fatty fish, and parental longevity showed positive associations with HDL-C, which were statistically significant. Smoking habit, sucrose consumption, and a family history of ischaemic heart dis…
Factors associated with urinary incontinence in women
Possible aetiological factors for urinary incontinence were examined in a prevalence study among a random sample of 1000 women aged 18 and over. Infective factors were not markedly associated with incontinence but mechanical factors such as parity and obesity were. No association was found, however, between a history of perineal damage at childbirth and incontinence. Women with incontinence had on average a higher score for a 'neuroticism' trait …
The prevalence and severity of urinary incontinence in women
One thousand and sixty women aged 18 or over, randomly selected from a defined geographical area in South Wales, were interviewed at home about their urinary symptoms. Ninety-five per cent co-operated, of whom 45% admitted to some degree of incontinence. "Stress' incontinence was reported by 22% of women, "urge' incontinence by 10%, and both types combined--"complex'--by 14%. In most women urinary loss was both small and infrequent but 5% of all …
Housing conditions, respiratory illness, and lung function in children in South Wales
The hypothesis was tested that respiratory illness in children occurs more commonly in old housing than in housing built to modern standards. Three areas of housing were chosen in a South Wales valley: a recently constructed council estate with district central heating; a modern council estate heated with open coal fires; and an area of much older, traditional valley housing. Mothers reported the greatest proportion of children free of colds and …
