Exposure to environmental tobacco smoke: Association with personal characteristics and self reported health conditions
STUDY OBJECTIVE: To examine the association between exposure to environmental tobacco smoke (ETS) and demographic, lifestyle, occupational characteristics and self reported health conditions. DESIGN: Cross sectional study, using data from multiphasic health checkups between 1979 and 1985. SETTING: Large health plan in Northern California, USA. PARTICIPANTS: 16 524 men aged 15-89 years and 26 197 women aged 15-105 years who never smoked. RESULTS: …
Mentholated cigarettes and non-lung smoking related cancers in California, USA
We sought to discover if the higher risk among men of lung cancer associated with menthola ted than with plain cigarettes1 applied as well to other smoking related cancers (upper aerodi gestive: mouth, pharynx, larynx, oesophagus; pancreas, renal adenocarcinoma, other urinary tract (urothelium), cervix). In 1979-1985, 79 946 subscribers of the Kaiser Permanente Medical Care Program in northern California, age 30-89 years, completed a detailed que…
Marijuana use and mortality
OBJECTIVES: The purpose of this study was to examine the relationship of marijuana use to mortality. METHODS: The study population comprised 65171 Kaiser Permanente Medical Care Program enrollees, aged 15 through 49 years, who completed questionnaires about smoking habits, including marijuana use, between 1979 and 1985. Mortality follow-up was conducted through 1991. RESULTS: Compared with nonuse or experimentation (lifetime use six or fewer time…

Misclassification of smoking status in the Cardia study: A comparison of self-report with serum cotinine levels
BACKGROUND. Although widely used in epidemiological studies, self-report has been shown to underestimate the prevalence of cigarette smoking in some populations. METHODS. In the CARDIA study, self-report of cigarette smoking was validated against a biochemical marker of nicotine uptake, serum cotinine. RESULTS. The prevalence of smoking was slightly lower when defined by self-report (30.9%) than when defined by cotinine levels equal to or greater…

Nongenetic influences of obesity on other cardiovascular disease risk factors: An analysis of identical twins
The importance of genetic influences on obesity has been emphasized recently. We conducted matched co-twin analyses of 250 pairs of White, male, monozygotic twins from the National Heart, Lung, and Blood Institute (NHLBI) Twin Study. Entirely in the absence of genetic influences, obesity was significantly associated with systolic and diastolic blood pressures; one-hour, post-load glucose; total, LDL-, and HDL-cholesterol; and triglycerides among …
Mentholated cigarette use among multiphasic examinees, 1979-86
Mentholated cigarette use was studied in relation to age and race in 29,037 current smokers who were Kaiser Permanente Medical Care Program members. The percentages of mentholated cigarette users were much higher in Blacks and Asians than in Whites, especially in the younger age groups. A marked inverse relationship between mentholated cigarette use and age was present in Blacks and Asians; mentholated cigarette use showed little difference with …
Thinness and mortality
The relationship of thinness to mortality was examined in White adult members of the Kaiser Permanente Medical Care Program who had at least three multiphasic health checkups between 1964 and 1972, with mortality follow-up through 1980. A detailed comparison was performed of the mortality patterns of "thin" (decile 1 of Quetelet's index) and "average" weight (deciles 4 and 5) cohort members who were age 40-79 years and free of illness at the begi…
Prevalence and correlates of passive smoking
The duration per week of exposure to others' tobacco smoke in different locations was tabulated from the questionnaire responses of 37,881 non-smokers and ex-smokers who received multiphasic health checkups in 1979 and 1980. Altogether 63.3 per cent of subjects reported some exposure, 34.5 per cent were exposed at least 10 hours per week, and 15.9 per cent at least 40 hours per week. Duration of exposure per week was weakly correlated with serum …
Characteristics of patients referred for treatment of end-stage renal disease in a defined population
We studied the incidence of referral for treatment of end-stage renal disease (ESRD) in the Kaiser Foundation Health Plan (KFHP) in northern California from 1972 through 1977. In this population of over 1 million persons, we found an age-adjusted annual incidence of 44.9 per million after 1973, when the Federal ESRD Program went into effect. Age-specific incidence was highest in in men greater than 70 years of age and in women in the 50- to 59-ye…
A survey of personal habits, symptoms of illness, and histories of disease in man with and without vasectomies
Using questionnaire information provided by 4.385 vasectomized and 13,155 matched, non-vasectomized men, we found no significant differences between them for a large number of symptoms and diseases, including those of the cardiovascular system. After taking into account differences in their martial status, past smoking habits, and physical activity at work, significant statistical associations of vasectomy with joint pain or swelling, back troubl…
Accuracy of information on smoking habits provided on self-administered research questionnaires
In the setting of a prepaid medical care plan, self-administered questionnaires were an accurate source of information on smoking habits and the standard against which the physiologic measures of smoking, serum thiocyanate, and expired carbon monoxide, must be judged. Questionnaire responses were internally consistent and highly reproducible. In contrast, the physiologic measures had low overall sensitivity as tests of current tobacco exposure (0…
