Although a number of factors have been found to predict smoking status among adolescents, few researchers have examined how belief in smoking as a weight-control strategy may be related to smoking in this high-risk population. With the goal of discovering whether belief in smoking as a weight-control strategy predicted smoking status, the present investigation surveyed 659 Black and White high school students. Analyses showed that among regular smokers, 39% of White female and 12% of White male smokers reported using smoking to control their appetite and weight. Although belief in smoking as a weight-control strategy did not predict regular smokers versus never smokers, the weight-belief item reliably separated experimental smokers from regular smokers. The survey also revealed that White female restrained eaters were the most likely to actually use smoking as a weight-control strategy.

This study evaluated the relationships between stages of change and related health behaviors in a population of smokers forced to quit smoking. Participants were 10,136 Air Force recruits who were in basic military training (BMT) and who were not allowed to smoke because of a ban on smoking during BMT. Participants were surveyed about their smoking history, their motivation and readiness to remain smoke free after BMT, and their behavior on 5 target health areas. Results indicated that smoking history best predicted stage of change. Though there were few gender differences, several ethnic differences emerged. These results suggest that, although stages of change involve both a cognitive and behavioral component, removing the behavioral component (smoking) through a smoking ban does not reduce the construct validity of the transtheoretical model.

This study evaluated the relationship between smoking and body mass using objective indices of both smoking exposure (COHb) and body mass. The subjects were 4240 adults who participated in the Second National Health and Nutrition Examination Survey (NHANES II). Measurements of dietary intake, physical activity, demographics, body mass index (BMI) and blood carboxy-haemoglobin (COHb) were used in these analyses. After controlling for covariables of body mass, the results indicated that smokers displayed a significantly lower mass compared with non-smokers. Smokers with higher levels of COHb had lower BMIs than smokers at lower COHb levels. White smokers had lower BMIs with increasing COHb exposure whereas black smokers had BMIs at high COHb exposure similar to those of non-smokers. Results indicated that smokers weighed less than non-smokers and that the weight control 'benefits' of smoking were most pronounced in white subjects who were heavy smokers. 相似文献

Empirical evidence regarding the causal nature of the relationship between emotional distress and tobacco use in male and female adolescents provides support for both the distress-to-use and the use-to-distress hypotheses. Using a cross-lagged model with 3 waves of data from 2,961 adolescents followed into young adulthood, the authors tested the hypothesis that this relationship changes over time. As hypothesized, emotional distress in Grade 10 was associated with increased smoking in Grade 12 for both boys and girls. Smoking in Grade 12 was in turn associated with increased emotional distress in young adulthood. The addition of 3 third factors (rebelliousness, deviance, and family problems) to the model did not alter the results. Results suggest that the relationship between tobacco use and emotional distress is a dynamic one in which distress initially leads to use but then becomes exacerbated by it over time.

Overweight people are at high risk of developing knee osteoarthritis (OA) and may also be at increased risk of hand and hip OA. Furthermore, being overweight accelerates disease progression in knee OA. While the increased joint stress accompanying obesity may explain the strong linkage between obesity and knee OA risk, it does not necessarily explain why obese people have a high risk of disease in the hand nor why obese women are at higher comparative risk of knee disease than obese men. Unfortunately, studies of metabolic factors linked to obesity have not provided an explanation for these findings. There are a paucity of data on weight loss as a treatment for OA, but preliminary information suggests it is especially effective in knee disease and that even small amounts of weight reduction may have favourable effects. 相似文献

Smoking cessation rates, progression in stage of change for smoking cessation, and serious quit attempts were examined over 2 years in a cohort of 242 men and women smokers (mean age 39.7 years, mean body mass index [BMI] 26.3) as a function of expressing concern about gaining weight because of quitting smoking. Participants were employees of 25 companies who were in a worksite health promotion program aimed at reducing risk factors for cardiovascular disease. Multivariate odds ratios (controlled for age, education, job class, sex, and BMI) for quitting smoking, attempting to quit smoking, and progressing in stage of change for smoking cessation as a function of weight concern were not significant. Interactions between sex and weight concern, and BMI and weight concern were also not significant. These findings, in a working, predominantly blue-collar population, and those of other studies, suggest that concern about gaining weight is, at best, a weak predictor of change in smoking behavior among most smokers.

PURPOSE: To calculate for two measures of obesity, the Metropolitan Relative Weight (MRW) and body mass index (BMI), the value at which minimum mortality occurs. This was done to retest the hypothesis, in the Framingham Heart Study data, that the association between obesity and mortality can be obscured by an interaction between the measure of obesity and smoking. In the original analysis of the Framingham data it was suggested that there was a U- or J-shaped relationship between MRW and death in smokers but a linear relationship in nonsmokers. The design and setting were those of the NHLBI Framingham Heart Study. METHODS: The 5209 members of the Framingham Heart Study underwent a baseline examination in 1948-1952 (Exam 1) and they were reexamined at approximately two-year intervals over a 30-year period. The study included both men (n = 2336) and women (n = 2873) in the age range of 28 to 62 years. After excluding persons with missing baseline data, the analytic sample size was 5163. Additional analyses were conducted by deleting persons with cardiovascular disease (CVD) at baseline (n = 135), the sample used by the original paper by Garrison and colleagues, and persons who died within the first four years of follow-up (n = 62). The main outcome measures consisted of thirty-year survival through Exam 16, approximately in 1980, as influenced by MRW or BMI, age, and smoking status at baseline (Exam 1). RESULTS: We were able to show that the sample sizes of male nonsmokers were too small to test the hypothesis within age groups < 40 and 40-49 years. In men ages 50-62 there was a significant age-adjusted quadratic relationship between BMI or MRW, and risk of death. The estimated BMI at the minimum risk of death for smokers (24.5) and nonsmokers (23.8) were not statistically different. Identical results were found for MRW (minimum: smokers = 112.5, nonsmokers = 111.4). In men and women ages 28-62 there appeared to be a u- or j-shaped relationship between the 30-year crude mortality rate and MRW. After excluding persons with missing data, CVD at baseline, and persons who died within the first four years of follow-up, the age adjusted estimated BMI value at the minimum risk of death was nearly identical for men and women and for smokers and nonsmokers (Men: smokers = 22.8, nonsmokers = 22.8; Women: smokers = 22.9, nonsmokers = 23.3). Additionally, the estimates of the minimum were always below the mean. Identical results were found without deleting persons with CVD at baseline and deaths in the first four years of follow-up. Identical results were found for MRW. CONCLUSIONS: Reanalysis of the Framingham Heart Study data does not support the hypothesis that there is an interaction between smoking and measures of obesity. Moreover, the estimated BMI or MRW at the minimum risk of death was similar for men and women smokers and nonsmokers alike even after deleting prevalent cases of CVD and deaths within the first four years of follow-up. 相似文献

Social–cognitive and behavioral theories of change disagree on what the relevant controlling variables for initiating behavior change are. Correlations between baseline smoking cessation self-efficacy and the changes in breath carbon monoxide (CO) and the reduction in breath CO and increases in smoking cessation self-efficacy from baseline were obtained from a contingency management smoking cessation procedure. A test of the difference between the cross-lag correlations suggested a nonspurious causal relationship between smoking cessation self-efficacy and changes in breath CO. Path analyses showed that decreases in breath CO (reductions in smoking) predicted later increases in smoking cessation self-efficacy. Baseline self-reports of smoking cessation self-efficacy were not significantly correlated with subsequent changes in breath CO. Rather, significant correlations were found between reductions in breath CO and later increases in smoking cessation self-efficacy. These results suggest that self-efficacy may be a cognitive response to one’s own behavior, and are inconsistent with a social–cognitive view of self-efficacy’s role in behavior change. Implications for the development of smoking cessation programs and health-promoting behavior changes in general are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

The purpose of this study was to document the extent of coronary heart disease (CHD) risk factors in military personnel (412 men, 50 women) classified as seriously overweight (body mass index [BMI] 27.0-29.9 kg/m2) or obese (BMI > or = 30 kg/m2) and to evaluate the utility of the BMI to discriminate among individuals with an adverse CHD risk profile. Mean body weight and BMI greatly exceeded Canadian norms, whereas mean heights were average. There were low but significant correlations between BMI and resting and submaximal exercise (stage A of the Canadian Aerobic Fitness Test) heart rates and blood pressures, while the correlation with predicted VO2max was negative. Except for blood glucose level (GLU) in men, there were no significant correlations between BMI and various biochemical indices. Compared to "overweight" men, the percentage of "obese" men with abnormal values for risk factors were higher, particularly for an adverse exercise blood pressure response and low predicted VO2max. In summary, the correlations between BMI and the various CHD risk factors, except for GLU and the exercise parameters, were minimal or moderate at best. It was concluded that in overweight and obese individuals, BMI does not appear to be a particularly sensitive indicator of body fat and risk factors. 相似文献

Assessed the relationship between self-efficacy, attributions, and weight loss in the context of a weight rehabilitation program. Pretreatment, posttreatment, and followup assessments of self-efficacy, weight loss, and success–failure attributions were obtained from 38 volunteer overweight women (aged 21–65 yrs) participating in the program. Self-efficacy was significantly enhanced as a result of treatment, although it was not significantly related to weight loss during treatment. However, changes in efficacy expectations during follow-up did coincide with weight change during those intervals. In addition, efficacy expectations alone at treatment termination were found to be a significant predictor of weight loss following a 6-wk and 6-mo follow-up. Success–failure attributions contributed significantly to the prediction of efficacy expectations during treatment and during the 6-wk follow-up. Weight loss during treatment was not a significant determinant of treatment-induced self-efficacy enhancement. Results are interpreted in light of the reciprocal interaction between actual behavior change and cognitive factors in the context of a rehabilitation program.

Previous research has indicated that abstinence early in a smoking cessation program is predictive of successful posttreatment abstinence. However, it has not been established whether or not this effect is independent of other in-treatment abstinence patterns. In this paper the relationship between three potentially important aspects of in-treatment smoking abstinence and posttreatment smoking abstinence are examined: early abstinence, extended abstinence, and end-of-treatment abstinence. We examined the relationship between smoking behavior measured each weekday over 70 visits (approximately 14 weeks) of a contingency management smoking cessation program and at a follow-up visit 6 months after study entry (3 months after the scheduled end of treatment). Ninety-five of 102 participants were successfully followed-up. Seven of these 95 participants were confirmed abstinent. Early abstinence, defined as abstinence during the first 10 treatment visits, was significantly and independently related to follow-up abstinence (OR = 56.67 [7.29–440.63]). Extended abstinence and end-of-treatment abstinence were related to follow-up abstinence, but not independent of early abstinence based on multiple regression models. Inclusion of a variety of demographic and environmental characteristics did not significantly alter this relationship. Thus, consistent with the previous literature, the establishment of early abstinence appears to be crucial to establishing longer-term abstinence, independent of other in-treatment abstinence patterns.

In this study, the authors prospectively evaluated the impact of a smoking lapse on relapse probability. After 4 days of smoking abstinence, 60 smokers were randomly assigned to smoke 5 nicotine-containing or 5 denicotinized cigarettes, or to remain abstinent (no lapse) during a 4-hr time period. Afterward, smoking abstinence was encouraged with monetary incentives, and smoking behavior was tracked for 6 days. Relative to the no-lapse condition, exposure to either of the cigarette types more than doubled the probability of subsequent smoking. Smoking outcomes did not differ between nicotine-containing and denicotinized cigarettes. The data suggest that stimulus factors may play an important role in lapse to relapse processes.

This study examined the relationship between smoking status and weight change from baseline to Year 7 in a large biracial cohort, the Coronary Artery Risk Development in Young Adults study. Unadjusted for covariates, only male smokers weighed less than nonsmokers, with no effect among women. Adjusted for covariates, male and female smokers weighed less than nonsmokers at baseline, adjusted for age, total energy intake, alcohol intake, and physical fitness. Over the 7-year follow-up, all smoking status groups gained weight, including continuous smokers and initiators. Weight gain was greatest among those who quit smoking. Weight gain attributable to smoking cessation was 4.2 kg for Whites and 6.6 kg for Blacks. Smoking had a small weight-attenuating effect on Blacks. No such effects, however, were observed among Whites. These results suggest, at least in younger smokers, that smoking has minimal impact on body weight. 相似文献

Used biographical variables, available at the time of admission to a Navy psychiatric service, to predict the posthospital adjustment of 827 male patients (Navy and Marine Corps personnel) to military life. Predictor variables were combined, using a multiple-regression technique and a simple item-analyzed scale. The latter proved to be slightly, but not significantly, more efficient than the multiple-regression procedure as judged from cross-validity correlations. Variables which were reliable prognostic indicators included (a) occupational specialty, (b) number of children, (c) wife's attitude, (d) solitariness of work, (e) length of service, (f) diagnosis, and (g) recognition for inservice achievements. While improvement on base-rate prediction was not possible, an increase in effectiveness rate for expsychiatric patients could be effected by selecting a high prognosis score as a requirement for returning a patient to duty.

Characteristics of highly physically active smokers in a population of young adult military recruits

A substantial number of cigarette smokers are thought to engage in regular exercise. It is unclear why individuals who engage in a health-promoting activity such as exercising would simultaneously engage in a health-damaging behavior like smoking. Two possibilities are that (1) exercise serves as a "harm reduction" strategy to lessen the negative effects of smoking, or (2) that among weight conscious individuals, exercise and smoking are both used as weight control strategies. To examine these issues, smoking status, physical activity level, weight concerns, and several additional health behaviors and attitudes were assessed by questionnaire in a population of United States Air Force recruits (n=32,144). Multiple logistic regression analyses were used to compare characteristics of highly physically active smokers with both highly physically active never-smokers, and less active smokers. A substantial proportion of smokers reported being highly physically active (15.8%), although this proportion was significantly higher for never-smokers (22.7%). Active smokers were similar to active never-smokers across several health behaviors and attitudes, including diet, seatbelt use, and attitudes toward illegal drugs and condom use. Compared to less active smokers, active smokers consumed more fruits and vegetables, worried less about their weight, were less nicotine dependent, and had greater previous success at quitting smoking. These findings indicate that a substantial proportion of highly physically active young adults are regular cigarette smokers. Based on findings regarding general health behaviors and smoking history, this group may be particularly amenable to smoking cessation efforts. 相似文献

The relationship between changes in relative weight and fitness was assessed 5 years after children began treatment for obesity. Multivariate regression analysis showed that two factors were independently related to fitness change: (a) maintenance of weight loss from the end of 6 months of treatment to the 5-year follow-up and (b) initial fitness level. Children who showed the largest long-term changes in relative weight and the lowest initial fitness showed the largest improvements in fitness. Short-term weight loss was not related to long-term fitness change. These results show that weight loss and fitness are related over 5 years.

OBJECTIVE: To assess the relationship between ethnicity and Health Care wishes, including Advance Directives, in a group of frail older persons in PACE (Program For All Inclusive Care Of The Elderly). DESIGN: Retrospective chart review of 1193 participants in the PACE program. SETTING: Program of All Inclusive Care Of The Elderly (PACE), a comprehensive managed care demonstration program serving frail older participants at 10 sites across the nation. PARTICIPANTS: A total of 1193 older adults, all of whom met state criteria for nursing home level of care. There were 385 non-Hispanic whites, 364 blacks, 156 Hispanics, and 288 Asians. MEASUREMENTS: Presence or absence of advance directives, type of health care wishes selected including living will, durable power of attorney, and health care proxy. RESULTS: Frail older white, black, Hispanic and Asian Americans differ significantly in their health care wishes and how they choose to express them. Blacks were significantly more likely to select aggressive interventions and less likely than non-Hispanic whites and Hispanics to utilize a written instrument for expressing health care wishes. Whites were significantly more likely to utilize written documents for advance directives, whereas Asians were more likely to select less aggressive interventions but were unlikely to use written advance directives. CONCLUSIONS: In this population, we found significant ethnic variations in choice of health care wishes. Although health care wishes are an individual decision, an awareness of cross cultural patterns can assist practitioners in addressing the concerns of their patients, as well as assisting Health Care Policy Development. 相似文献

BACKGROUND: The objective of this study was to examine the relationship between religious activities and cigarette smoking in community-dwelling older adults. METHODS: Cigarette smoking and religious activities were assessed in a probability sample of 3968 persons age 65 years or older participating in the Duke Populations for Epidemiologic Studies of the Elderly (EPESE) survey. Participants were asked if they currently smoked, if they ever smoked, and how many cigarettes per day they smoked. Attendance at religious services, participation in private religious activities (prayer or Bible study), and use of religious media (religious TV or radio) were also assessed. Data were available for Waves I-III of the survey (1986, 1989, and 1992). Analyses were controlled for age, race, sex, education, alcohol use, physical health, and in the longitudinal analyses, smoking status at prior waves. RESULTS: Cross-sectional analyses revealed that participants who frequently attended religious services were significantly less likely to smoke cigarettes at all three waves. Likewise, elders frequently involved in private religious activity were less likely to smoke (Waves II and III). Total number of pack-years smoked was also inversely related to both attendance at religious services and private religious activities. Watching religious TV or listening to religious radio, on the other hand, was not related to smoking at Waves I and II nor to total pack-years smoked, but was positively related to current smoking at Wave III. Among those who smoked, number of cigarettes smoked was inversely related to frequency of attendance at religious services (Wave I), private religious activities (Wave III), and religious TV/radio (Waves II and III). Retrospective and prospective analyses revealed that religiously active persons were less likely to ever start smoking, not more likely to quit smoking. CONCLUSIONS: Religiously active persons are less likely to smoke cigarettes, and if they do smoke, smoke fewer cigarettes. Given the association between smoking and disease, and the widespread prevalence of both smoking and religious activity, this finding has implications for public health. 相似文献
