Study Objective: To describe the relationship between risk factors, risk behaviours, symptoms and mortality from cardiorespiratory diseases in an urban area with high levels of socioeconomic deprivation. A cohort study of 15,411 men and women aged 45-64, comprising 80% of the general population of Paisley and Renfrew, Scotland., Outcomes: Mortality after 15 years from coronary heart disease(ICD 410-4), stroke(ICD 430-8), respiratory disease(ICD 460-519) and all causes., Main Results: Mortality rates from all causes were 19% in men aged 45-49, 31% in men aged 50-54, 42% in men aged 55-59 and 57% in men aged 60-64. The rates are considerably higher than those reported in previous UK prospective studies. For women the rates were 12%, 18%, 25% and 38% respectively. In general men and women showed similar relationships between risk factor levels and mortality rates. People in manual occupations had higher mortality rates. Raised levels of systolic and diastolic blood pressure were associated with increased coronary, stroke and all cause mortality rates. Plasma cholesterol had no such association with all cause mortality rates. High and low levels of body mass index were associated with higher mortality rates than intermediate levels. A relationship between short stature and increased mortality rates was observed in men and women. FEV1 expressed as a percentage of the expected value showed the strongest relationship with mortality rates, particularly for respiratory disease, but also for deaths from coronary heart disease, stroke and all causes., Conclusions: A similar pattern of relationship between risk factor levels and mortality rates exists in men and women in Renfrew and Paisley. Respiratory impairment as measured by FEV1% predicted appears to be the most likely explanation of the observed high all cause mortality rates in this population.

Unlabelled: STUDY OBJECTIVE. To describe the distribution of risk factors, risk behaviors, symptoms and the prevalence of cardiorespiratory disease in men and women in an urban area with high levels of socioeconomic deprivation. A cross-sectional survey of 15,411 men and women aged 45-64, comprising an 80% response rate from the general population in Paisley and Renfrew, Scotland., Main Results: The main characteristics of the male Renfrew/Paisley population, compared to previous British studies, were shorter stature, higher blood pressure, a higher proportion of smokers who continue to smoke, lower FEV1 and higher levels of reported angina, breathlessness on effort and chronic bronchitis. In comparison with men, the main characteristics of the female Renfrew/Paisley population were shorter stature, higher plasma cholesterol, lower FEV1, fewer current and ex-smokers, and a higher prevalence of breathlessness on effort. There were only small differences between men and women in the prevalence of angina, ECG evidence of myocardial ischaemia and chronic bronchitis., Conclusions: Middle-aged men and women in an urban area with high levels of socio-economic deprivation have different cardio-respiratory risk and disease profiles compared to previous population in the UK, based on occupational groups and random national samples.

Unlabelled: OBJECTIVE-To assess the risk of cardiorespiratory symptoms and mortality in non-smokers who were passively exposed to environmental smoke., Design: Prospective study of cohort from general population first screened between 1972 and 1976 and followed up for an average of 11.5 years, with linkage of data from participants in the same household., Setting: Renfrew and Paisely, adjacent burghs in urban west Scotland., Subjects: 15,399 Men and women (80% of all those aged 45-64 resident in Renfrew or Paisley) comprised the original cohort; 7997 attended for multiphasic screening with a cohabitee. Passive smoking and control groups were defined on the basis of a lifelong non-smoking index case and whether the cohabitee had ever smoked or never smoked., Main Outcome Measure: Cardiorespiratory signs and symptoms and mortality., Results: Each of the cardiorespiratory symptoms examined produced relative risks greater than 1.0 (though none were significant) for passive smokers compared with controls. Adjusted forced expiratory volume in one second was significantly lower in passive smokers than controls. All cause mortality was higher in passive smokers than controls (rate ratio 1.27 (95% confidence interval 0.95 to 1.70)), as were all causes of death related to smoking (rate ratio 1.30 (0.91 to 1.85] and mortality from lung cancer (rate ratio 2.41 (0.45 to 12.83)) and ischaemic heart disease (rate ratio 2.01 (1.21 to 3.35)). When passive smokers were divided into high and low exposure groups on the basis of the amount smoked by their cohabitees those highly exposed had higher rates of symptoms and death., Conclusion: Exposure to environmental tobacco smoke cannot be regarded as a safe involuntary habit.
