Impact of different lifestyle indexes on serum uric acid levels in young and middle-aged men / 中华内分泌代谢杂志

Objective:To investigate the impact of lifestyle index (LSI) on serum uric acid levels in young and middle-aged men.Methods:This was a cross sectional study. A total of 8 067 subjects underwent check-up in Taihu Sanatorium of Jiangsu Province from March 2020 to June 2021 were enrolled, average age were(46.46±8.81) years. According to age, subjects were divided into young male group (18-44 years old, n=3 269) and middle-aged male group (45-60 years old, n=4 798). Height, weight, body mass index, alcohol drinking, smoking, diet, exercise, fasting blood glucose, total cholesterol, triglycerides, high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol(LDL-C), serum uric acid and other data in all cases were measured and recorded. Results:The serum uric acid level in allsubjects was (376.80±74.43)μmol/L and the prevalence of hyperuricemia was 25.7%.The serum uric acid level in the young male group was higher than that in the middle-aged male group [(381.86±74.32)μmol/L vs (373.34±74.32)μmol/L, P<0.001]. The prevalence of hyperuricemia in the young male group was higher than that in the middle-aged male group (27.4% vs 24.5%), and the difference was statistically significant ( P<0.001). With the improvement of LSI scores, the serum uric acid levels in young and middle-aged men showed a decreasing trend ( P<0.01). Logistic regression analysis showed that after adjusting for age, fasting blood glucose, total cholesterol, triglyceride, HDL-C, LDL-C, hypertension, and diabetes, LSI was an independent factor for serum uric acid levels in young and middle-aged men. The risk of hyperuricemia in young and middle-aged male decreased ( OR 0.83 and 0.84, respectively, P<0.01) for every 1-point increase in LSI. Exercise and body mass index were independently associated with hyperuricemia in the young male group ( OR 0.83 and 0.54, respectively, P<0.05). Exercise, body mass index, and alcohol drinking were independently associated with hyperuricemia in the middle-aged male group ( OR 0.85, 0.51 and 0.65, respectively, P<0.05). Conclusion:LSI is an independent factor associated with hyperuricemia in young and middle-aged men and a healthy lifestyle has a protective effect on serum uric acid levels in young and middle-aged men.

Engagement in different sport disciplines during university years and risk of locomotive syndrome in older age: J-Fit

BACKGROUND@#Among former Olympic-level athletes, engagement in different sport disciplines has been associated with mortality risk in subsequent years. However, limited evidence is available on whether engagement in different sport disciplines at a young age is associated with locomotive syndrome (LS) risk later in life. This study examined the relationship between engagement in different sport disciplines during university years and LS risk in older age among former university athletes.@*METHODS@#Participants were 274 middle-aged and 294 older men alumni who graduated from a school of physical education in Japan. LS risk was defined as answering "yes" to any of the Loco-check questions. Data on university sports club membership were collected using questionnaires. University clubs were classified into three groups of cardiovascular intensity (low, moderate, high), following the classification system of sport disciplines by the American College of Cardiology. This classification considers the static and dynamic components of an activity, which correspond to the estimated percent of maximal voluntary contraction reached and maximal oxygen uptake achieved, respectively. University clubs were grouped based on the risk of bodily collision (no, yes) and extent of physical contact (low, moderate, high). Relationships between engagement in different sport disciplines and LS risk were analyzed using Cox proportional hazards models, and adjusted for age, height, weight, joint disease, habitual exercise, and smoking and drinking status.@*RESULTS@#Adjusted hazard ratios and 95% confidence intervals associated with the low, moderate, and high cardiovascular intensity sports were 1.00 (reference), 0.48 (0.22-1.06, P = 0.070), and 0.44 (0.20-0.97, P = 0.042) in older men, respectively; however, there was no significant association between these parameters among middle-aged men. Engagement in sports associated with physical contact and collision did not affect LS risk in either group.@*CONCLUSIONS@#Engagement in sports associated with high cardiovascular intensity during university years may reduce the risk of LS in later life. Encouraging young people to participate in such activities might help reduce LS prevalence among older populations.

Health behaviors and health status of Korean middle-aged men by marital status: Korea Community Health Study, 2015 / 한국역학회지

OBJECTIVES: Previous studies have shown that marital status is associated with household composition and living arrangements, which partially explain observed differences in health status according to marital status. However, due to the rapid socioeconomic and demographic transformations of the last few decades, the distribution of marital status among middle-aged adults has become more diverse. Therefore, this study aimed to obtain up-to-date information on the associations between marital status and health and to investigate the implications of these findings for conventional explanations of the health effects of marriage.METHODS: The data for this study were obtained from the 2015 Korean Community Health Study. We compared 4 modifiable lifestyle behaviors—smoking, alcohol consumption, physical activity, and self-rated health status—as outcome variables in association with marital status in Korean middle-aged men (age 40-44) living in Seoul and other regions.RESULTS: Married men showed the lowest cigarette smoking prevalence and the highest subjective health status both before and after adjusting for education and income. The odds of engaging in vigorous physical activity did not show a major difference before and after adjustment for income and education.CONCLUSIONS: In married men, the prevalence of cigarette smoking was lowest and subjective health status was highest, similar to previous studies. However, the prevalence of engaging in physical activity was highest in divorced/widowed/separated men. The health behaviors and health status of Korean middle-aged adults should be more closely followed, since they are representative of demographic changes in the Korean population.

Metabolic Syndrome Risk by Intake Ratio and Intake Pattern of Proteins in Middle-aged Men Based on the 2012-2013 Korean National Health and Nutrition Examination Survey Data / 대한지역사회영양학회지

OBJECTIVES: The purpose of the study was to compare intake of energy nutrients, physical characteristics, and the prevalence of metabolic syndrome according to protein intake group. METHODS: Subjects were 827 men aged 40-65 years. The results presented were based on data from the 2012-2013 National Health and Nutrition Examination Survey and analyzed using SPSS. The odds ratio (OR) of metabolic syndrome was assessed according to the protein intake group and intake pattern of protein-rich foods. RESULTS: The mean of protein intake was 73.96 ± 0.71 g. According to level of protein intake, four groups (deficient, normal, excess 1, excess 2) were created and their percentages were 8.3%, 39.6%, 37.1%, and 15.0% respectively. The mean of daily energy intake was 2,312.33 ± 24.08 kcal. It was higher in excess group 2 than in the deficiency group (p < 0.001). Moreover, the intake of all energy nutrients increased significantly with protein intake group (p < 0.001). The main contribution to daily protein included mixed grains (10.96 ± 0.32 g), milled rice (7.14 ± 0.30 g), chicken (3.50 ± 0.21 g), and grilled pork belly (3.04 ± 0.16 g). With regard to physical characteristics, and blood pressure and blood test results, only body mass index increased significantly according to protein intake groups (p < 0.05). The prevalence of metabolic syndrome in subjects was 38.5%, and there was no significant correlation with protein intake group. The OR of metabolic syndrome increased with protein intake, and was higher 4.452 times in excess group 2 than in the normal group (p < 0.05). Conversely, the OR of metabolic syndrome according to the frequency of protein-rich food intake did not show a significant correlation. CONCLUSIONS: The results of this study can be used as significant supporting data to establish guidelines for protein intake in middle-aged men.

Role of novel risk factors in predicting risk of ischemic cardiovascular diseases in middle aged men in twenty years in Shanghai / 中华流行病学杂志

Objective To examine the existing Framingham Risk Score (FRS) and Chinese Risk Score (CRS) in predicting the development of ischemic cardiovascular diseases (ICVD),and determine potential added value of novel risk factors.Methods The China Multi-Provincial Cohort Study (CMCS) was a population-based prospective cohort study in 11 provinces of China.An annual follow up was conducted in 840 men aged 35 to 64 years in Shanghai cohort,who were without coronary heart disease and stroke at baseline examination in 1992,to collect the incidence data of ICVD events (coronary death,myocardial infarction,and ischemic stroke).The detection of novel risk factors were conducted for the cohort in 2007.The basic Framingham and Chinese prediction scores power were assessed by using C-statistic of ICVD events associated with risk scores,then the novel risk factors were evaluated by adding them independently to the basic Chinese models.The area under the curve (AUC),net reclassification improvement (NRI),and integrated discrimination improvement (IDI) were calculated to determine if each of the novel risk factors improved risk prediction.Results By the end of December 2014,24 cases of coronary heart disease (myocardial infarction or/and coronary death),45 cases of ischemic stroke had occurred in 840 subjects in Shanghai cohort with a follow-up of 22.3 years averagely.Both the FRS and CRS had predicting power for ICVD,the AUCs were 0.657 6 (95％ CI:0.594 2-0.724 0) and 0.726 5 (95％ CI:0.664 3-0.788 7),respectively.The incremental AUC was 0.068 9 (95％ CI:0.019 6-0.117 1) (P=0.006).None of the novel risk factors significantly improved the AUC.High-sensitive-CRP (hs-CRP) was the only novel risk factor resulting in a significant increase of NRI.CRS in 2007 significantly improved the IDI,but net changes were small.Conclusions CRS had high power in the 20-year risk prediction for ICVD in middle-aged men in Shanghai.The inclusion of hs-CRP could make some improvement in risk prediction,but is unlikely to be meaningful when reclassification or new discrimination strategy are made which can change the clinical risk.

A study on the relationship between smoking and blood inflammatory cytokines as well as atherosclerosis / 预防医学

Objective To explore the influence of long -term smoking on the level of blood inflammatory cytokines and the degree of atherosclerosis in healthy middle -aged men.Methods A total of 84 middle -aged men who accepted the health examination were divided into smoking group and non -smoking group.The risk factors of atherosclerosis,such as age,body mass index (BMI),systolic blood pressure (SBP),diastolic blood pressure (DBP),fasting blood glucose (GLU),total cholesterol (TC),low density lipoprotein (LDL),high density lipoprotein (HDL)and triglyceride (TG) were recorded.The white blood cell (WBC)level and neutrophil cell (NC)level were also recorded.The interleukin -6 (IL -6)concentration was assayed by using enzyme -linked immunosorbent double antibody method and the high -sensitivity C reactive protein (Hs -CRP)concentration was assayed by using immune turbidimetry method.The carotid artery intima -media thickness (IMT)and plaques were measured by B -mode ultrasonography.Results There were no significant differences in the risk factors of atherosclerosis between the two groups.But there were statistically significant differences between smoking group and non -smoking group in IL -6 (1 .46 ±0.27 vs.1 .21 ±0.24),Hs -CRP (6.57 ±2.47 vs.3.1 4 ±2.07),WBC (5.78 ±0.79 vs.5.25 ±0.64)and NC (3.40 ±0.45 vs.2.87 ±0.42)(P <0.05). The carotid artery IMT in smoking group was significantly thicker than that of the non -smoking group (1 .0 ±0.1 8 vs. 0.82 ±0.1 6,P <0.01 ).The detection rate of plaque and carotid stenosis in smoking group was significantly higher than that of the non -smoking group (P <0.01 ).Conclusion Long -term smoking not only leads to increased inflammatory cytokines,but also aggravates the degree of atherosclerosis in healthy middle -aged men.Long -term smoking healthy middle -aged men are potential in patients with cardiovascular disease.

Dietary Factors and Metabolic Syndrome in Middle-Aged Men / 農村醫學 地域保健

OBJECTIVES: This study aims to identify dietary factors related to metabolic syndrome in middle aged Korean men who were participants in the Fourth Korea National Health and Nutrition Examination Survey(KNHANES IV) in 2007. METHODS: The study targeted 361 of the 709 men aged between 40 and 64 years for a final analysis; the other 348 surveys had incomplete data which did not allow for the determination of metabolic syndrome. The definition of metabolic syndrome was based on the National Cholesterol Education Program Adult Treatment Panel III(NCEP ATP III). RESULTS: There were significant differences in the metabolic syndrome of middle-aged men according to age, smoking pack-years, and number of resturant meals per week. Dietary factors such as vitamins, riboflavin, natrium, carbohydrate, protein and lipid intakes were not significant. CONCLUSIONS: It was verified that metabolic syndrome in middle-aged men is related to age, smoking pack-years and number of resturant meals per week. Dietary factors were not significantly related. However, further detailed studies in this area are needed.

Relationship between Metabolic Syndrome and Aging Male Symptoms in Middle-Aged Males in Korea / 가정의학회지

BACKGROUND: Metabolic syndrome is regarded as a risk factor of cardiovascular disease. We observed and compared aging males symptoms (AMS) between healthy and metabolic syndrome patients in middle-aged Korean men to evaluate clinical significance of AMS. METHODS: From May 2009 to July 2009, 171 middle-aged men (over 40 years-old) who visited a health promotion center of a university hospital in Gyeonggi Province were enrolled in study. The subjects were divided into two groups; metabolic syndrome (N = 87) vs. control (N = 84) and measured the aging male symptoms (AMS) scale. AMS were also grouped according to its severity. RESULTS: There were no significant differences except, weight, body mass index between two groups. In AMS severity, 'severe' group show higher prevalence of metabolic syndrome. And the group of metabolic syndrome gets higher AMS score than control. Among the five constitutive factors of metabolic syndrome, the prevalence of fasting blood sugar (> or = 100 mg/dL) and triglyceride (> or = 150 mg/dL) level is higher 'moderates' and 'severe' groups in AMS severity. In the subscale analysis of AMS, there are significant differences between two groups in sexual and somato-vegitative axis, but are not in psychological axis. With age-adjusted analysis, the results still show same trend. CONCLUSION: It might be necessary to approach aging males symptoms comprehensively during the management of metabolic syndrome in middle-aged men. And it could be helpful in treatment to recognize and control metabolic syndrome factors for the patients with severe aging males symptoms.

A Study on Nutrient Intakes and Blood Lipids of Middle Aged Men Living in Jeonbuk Province by Percentage of Body Fat / 대한지역사회영양학회지

The purpose of this study was to compare nutrient intakes and blood lipids according to the obesity index of middle aged men. Subjects were assigned to one of the following groups based on percentage of body fat (%Fat),; normal weight (10-20% fat), overweight (20-25% fat) and obesity (over 25% fat). Nutrient intakes were evaluated based on questionnaires and 24 hour recall method and blood lipids were analyzed by blood analyzer. The results were as follows: 1) Nutrient intakes were that carbohydrate intake rate in obesity group was lower than normal group and lipids intake rate in obesity group was higher than normal group. The intake of riboflavin and folic acid were differ normal and obesity group (p < 0.05), and normal group ingested under recommended intake. 2) Total-cholesterol, LDLcholesterol and blood pressure in obesity group were higher than normal group but the differences were not significant. The attack rate of coronary heart disease and blood glucose in obesity group is higher than normal group (p < 0.05). 3) The correlation of anthropometric measurements, blood lipid, blood glucose and blood pressure had significant results. Soft lean mass was associated BMI (p < 0.01), TC (p < 0.05), HDL (p < 0.05), LDL (p < 0.05) and SBP (p < 0.05). TG was associated TC (p < 0.05), HDL (p < 0.01), VLDL (p < 0.001) and Risk (p < 0.01). TC was associated LDL (p < 0.01) and Risk (p < 0.01). Blood glucose was associated TC (p < 0.05), LDL (p < 0.05), SBP (p < 0.05) and DBP (p < 0.05). These results suggest that reduction of body weight for the attack risk of obesity group in coronary heart disease.

Lifestyle in Relation to Increase in Weight in Korean Middle-aged Men

BACKGROUND: The relationship of lifestyle and socioeconomic factors with weight change over 4 years in Korean middle-aged group was assessed. METHODS: A total of 1,167 men, aged 40~59 years, were selected from the Health Promotion Center of Ulsan University Hospital during the period of Jan. 2000 through Mar. 2000. Including anthropometric measures, designed questionnaires were administered concern lifestyle behavior topics with cigarette smoking, exercise, alcohol consumption, dairy product consumption and socioeconomic factors of monthly income and education. The subjects were divided into three groups by body mass index (BMI: kg/m(2)); normal ( or =25 kg/m(2)). After 4 years of follow-up, the men were classified into weight change categories; 1) stable weight group (from normal to normal, from overweight to overweight) and 2) weight gain group (from normal to overweight/obesity, from overweight to obesity). RESULTS: The weight gain group were 18.4% (n=215) and the stable overweight group were 81.6% (n=952). Adjusted for age, the frequency of dairy product consumption, the frequency of alcohol drinking, the regularity of exercise, education and monthly income, the smokers (> or =10/day) had significantly high incidence rates of increase in weight (odds ratio=1.77, 95% CI 1.07~2.90). The increased dairy consumers (> or =4/week) had significantly low incidence rates of increase in weight (odds ratio=0.43, 95% CI 0.20~0.93). Otherwise, there were no significant relationships in weight change. CONCLUSION: Smoking and decreased dairy product consumption were related to the increase in weight.

A Study on Body Compositions and Food Behaviors of Middle Aged Men Living in Jeonbuk Province by Percentage of Body Fat / 대한지역사회영양학회지

The purpose of this study was to compare the body compositions and food behaviors of middle aged men with different obesity indices. The subjects were 62 middle aged men who lived Gunsan city. Heights, body weights, soft/lean masses, fat masses, percentages of body fat, and fat distributions were measured. Food habits and health-related lifestyle habits were evaluated based on questionnaires. The subjects were assigned to one of the following groups based on their percentage of body fat (%Fat); normal, overweight and obesity. The results were as follows: their heights, fat masses, percentages of body fat, WHR, RBW, BMI and fitness scores were significantly higher in the obese subjects when compared to the normal and overweight subjects. Self-perceptions of weight and desires of weight control were significantly related with their percents of Fat. The overweight and the obese groups skipped meals, ate supper out, ate snacks, smoked tobacco, and exercised less frequently than the normal group. There were no significant differences in the scores of the dietary habits and drinking of alcohol among the three groups. Therefore, proper nutritional education on regular meals and intervention is required if middle aged men want to be of normal weight and have healthy lifestyles.

The Relationship between Health Promoting Behaviors and Anger in Middle-Aged Men / 기본간호학회지

PURPOSE: The purpose of this study was to identify health promoting behaviors and the relationship between health promoting behaviors and state and trait anger in middle-aged men. METHOD: In this descriptive correlational study, the participants were 143 middle-aged men who lived in D city. Data were collected from November, 2004 to January. 2005. Personal interviews with a structured questionnaire were used. The data were analyzed using descriptive statistics, and Pearson correlation coefficients with SPSS Win 11.0 program. RESULTS: The score for health promoting behavior in the middle-aged men was above the mean score, The highest dimension was self-actualization and the lowest dimension of health promoting behaviors was exercise. A significant negative correlation was found between health promoting behaviors and state anger in middle-aged men. But there was no significant correlation between health promoting behaviors and trait anger. CONCLUSION: These results suggest that state anger should be considered as an important factor when nurses develop educational programs to enhance health promoting behavior in middle-aged men.

Relationship between Fatigue Severity and Heart Rate Variability in Middle-Aged Male Workers / 대한산업의학회지

OBJECTIVES: This study investigated the relationship between the severity of fatigue and the cardiac autonomic function by analyzing the heart rate variability on middle-aged male workers. METHODS: The severity of fatigue and heart rate variability were assessed with the control measures of age, body mass index, blood pressure, alcohol consumption, smoking history, regular exercise on 82 healthy middle-aged male workers in an annual health checkup. The severity of fatigue was evaluated by the Fatigue Severity Scale (FSS), which was developed by Krupp. The 5-minute electrocardiographic recordings were analyzed as a function of the time and the frequency domain methods of the heart rate variability (HRV). Standard Deviation of the NN intervals (SDNN), Root-Mean-Square of Successive Differences (rMSSD), Total Power (TP), Low Frequency (LF: 0.04~0.15 Hz) power, High Frequency (HF: 0.15-0.4 Hz) power, LF/HF ratio were used as the indices of the HRV. For a comparison of autonomic nervous functions and other variables, the subjects were divided into three fatigue groups based on the FSS score as follows: low (N=31), moderate (N=33), high (N=18) fatigue groups. RESULTS: There were no significant differences in age, blood pressure, heart rate, body mass index, alcohol consumption, or regular exercise except for the smoking history among the groups. In addition, there were no significant differences in the time domain analysis (SDNN, rMSSD) of HRV among the groups. Spectral analysis of the HRV showed that the mean amplitudes of the HF and LF component were lower in the high fatigue group, whereas there was no significant difference in the LF/HF ratio among the fatigue groups. There were no significant differences in the HRV indices between the smoking and non-smoking groups. No significant interacting effects between the severity of fatigue and smoking on the HRV were observed. CONCLUSIONS: The association between severe fatigue and the reduced high and low frequency components of the HRV in middle-aged male workers reflects a dysregulation of the cardiac autonomous control. Although the pathophysiological mechanism of this association remains unclear, these results might explain their increased risk for cardiovascular disease. However, these effects need to be confirmed through a well-designed prospective study.

The Relationship among Testosterone, IGF- 1 and Fat Mass

BACGROUND: The age-related increase in fat mass seems related to decrease in hormone level. Few studies have been done in Korea concerning the association between testosterone, GH (growth hormone) and fat mass. This study was undertaken to evaluate the relationship among testosterone, IGF-1 and fat mass. METHODS: The study was performed from February to October 2001 in the Health Screening Center of Pundang CHA Hospital with 243 men as subjects. Fat intake was measured through interview with diet therapist and other data were obtained by self-questionnaire. Fat mass was measured using Inbody 3.0 and the level of total testosterone, SHBG and IGF-1 in serum were measured. RESULTS: Smoking was negatively correlated with fat mass and WHR (waist to hip ratio) (P <0.05) and fat intake was positively correlated with fat mass (P <0.05). Fat mass was negatively correlated with total testosterone, calculated free testosterone, and SHBG (gamma = 0.26; P <0.01, gamma = 0.15; P <0.05, gamma = 0.31; P <0.01). WHR was positively correlated with age (gamma =0.26; P <0.01) and negatively correlated with total testosterone, calculated free testosterone, and IGF-1 (gamma = 0.24; P <0.01, gamma = 0.20; P <0.01, gamma = 0.16; P <0.05). After adjustment for age, body mass index, smoking, and fat intake, the calculated free testosterone and IGF-1 were independently negatively correlated with fat mass (beta = 0.072; P <0.01, beta = 0.0035; P <0.05) and WHR (beta = 6.9E-04; P <0.05, beta = 4.0E-05; P <0.05) but, total testosterone and SHBG were not independently correlated with fat mass and WHR. CONCLUSION: The results indicate that the calculated free testosterone and IGF-1 can be independent determinants of fat mass and WHR in middle-aged men.

A Study of Quality of Life in Middle-aged Men / 간호학회지

PURPOSE: This study was undertaken to examine the degree of quality of life and to analyze the factors affecting those quality of life in middle-aged men. METHOD: The subjects of this study were 208 men aged by 35-55 from 3 business enterprises located in Seoul and Incheon. Data collection was conducted through the use of 5 questionnaire. RESULT: There were significant differences in the quality of life according to marital status, religion, educational level, number of children and total house income. A positive correlation was found between quality of life and all independent variables i.e., health promoting behaviors, health perception, social support, self-esteem and self-efficacy. Stepwise Multiple Regression Analysis revealed that the most powerful predictor was self-esteem. Self- esteem, health perception, health promoting behaviors, marriage, and social support accounted for 65% of the variance in quality of life in middle-aged men. CONCLUSION: All independent variables i.e., health promoting behaviors, health perception, social support, self-esteem and self-efficacy were related with quality of life in middle-aged men. Therefore it is necessary to develop the nursing intervention with these variables to increase the quality of life for middle-aged men.

Analysis of Smoking Temptation, Nicotine Dependency, Perceived Health Status corresponding to Stage of Change in Smoking Cessation in Middle Aged Men / 기본간호학회지

This study was done to investigate the relation of smoking temptation, stage of change in smoking cessation, nicotine dependency and perceived health status in middle aged men. Convenience samples of 176 subjects who were either smoked or used to smoke, aged between 30 to 64, living in Seoul and Kyungi province area in Korea were selected for the study. The data was collected from December 1, 1999 to June 30, 2000. The research instrument were Stage of Change of Smoking Cessation Measure (DiClemente et al., 1991), Smoking Temptation Measure (Velicer, DiClemente, Rossi, Prochaska, 1990), Perceived Health Status Measure (McDowell & Newell, 1996), and Nicotine Dependency Scale (FTQ: Fagerstrom, 1978). The data were analyzed using the SAS Program. The result of the study are as follows: 1. The analysis of variance and multiple comparison showed that according to the stage of change, there were significant mean differences in the three sub-factors of smoking temptation; 'positive affect situation (F=12.64, p=.0001)', 'negative affect situation (F=16.01, p=.0001)', 'habitual craving situation (F=14.43, p=.0001)' and nicotine dependency (F=4.12, p=.0033) The mean score for smoking temptation for the subjects who were in the precontemplation stage outweighed the mean score for smoking temptation for subjects who were in the maintenance stage. 2. Through discriminant analysis, it was found that negative affect situation was the most influential variable of the smoking temptation sub-factors which can be used to discriminate stage of change. 3. The analysis of Pearson correlation coefficients showed that there was a significant positive relation between nicotine dependency and negative affect situation of smoking cessation((r=0.2182, p=0.0045) and a significant negative relation between nicotine dependency and perceived health status(r=-0.2115, p=0.0059).

Decisional balance corresponding to the Stage of Change of Smoking Cessation in Middle Aged Men / 기본간호학회지

PURPOSE: This study was done to identify the factors of decisional balance for smoking cessation among middle aged men in Korea. This was composed of a set of variables at the level of decision making when middle aged men decide to stop smoking. It was used to classify and identify the characteristics of the stages of change for smoking cessation to which the middle aged men belong, and was used to identify the variables of decisional balance which influenced the stages of change for smoking cessation in middle aged men. METHODS: A convenience sample of 169 men who had smoked and were smoking, were between age 30 and 60 and lived in Seoul(mean age=44), were selected from the community. The data was collected from December 10, 1999 to February 28, 2000. The research instrument was the Decisional Balance Measure for Smoking Cessation (Velicer et al., 1985), and Stage of Change Measure(DiClemente et al., 1991). The data were analyzed using the SAS Program. RESULTS: 1. According to stage of change measure, the 169 subjects were distributed in each stage of change for smoking cessation: in the pre-contemplation stage 63 subjects (32.7%), contemplation stage 60 subjects (35.5%), preparation stage 17 subjects (10.1%), and maintenance stage 29 subjects(17.2%). 2. Factor analysis identified 4 factors of decisional balance as appropriate factors for smoking cessation of middle aged men. There were named by the researchers; 1)'Perceived Burden to Self', 2) 'Perceived Benefit to Others' 3)'Perceived Approval to Others', and 4)'Perceived Disapproval to Self'. 3. Analysis of variance showed that the three components, 1)'Perceived Burden to Self(F=8.50, P=0.0001)', 2) 'Perceived Benefit to Others(F=3.19, P=0.025)' and 3)'Perceived DisApproval to Self(F=2.87, P=0.038)were significantly associated with stage of change. 4. Through discriminant analysis, it was found that 'Perceived Burden to self' was the most influential variable in discriminating the four stages of change(pre-contemplation, contemplation, preparation, and maintenance). CONCLUSION: The results are consistent with the application of the Transtheoretical model, which has been used to understand how people change health behavior. Even though this study is a cross-sectional, not a longitudinal study, the findings of this study give useful information for smoking cessation intervention for the middle aged men.
