Differences over the life span in daily life-style regularity.

A diary-based instrument-the Social Rhythm Metric (SRM)-was used to assess the level of stability of daily social and behavioral rhythms in a group of 239 healthy subjects (112 male, 127 female) ranging in age from 20 to 89 years. Each subject completed the instrument for two consecutive weeks, which were averaged to yield one measure (SRM score) of life-style regularity [range 0 (least regular) to 7 (most regular)] and another of activity level index (ALI), corresponding to the number of (diary listed) activities done per week (max. = 119). SRM score increased reliably with age group at an average rate of 0.018 units per year. ALI showed an "inverted U"-shaped function with a maximum at about 50 years. SRM changes appeared not to be related to demographic differences between the age groups, although ALI differences may have been so related. No main effects or interactions were found with gender. Life-style regularity appears to increase over the life span in response to both biological and psychosocial changes and may represent an adaptation to age-related changes in the circadian system's sensitivity to entraining agents. Regular behavioral rhythms may be conducive to continued good health and well-being.

General and dental health in relation to life-style and social network activity among 67-year-old Danes.

The present study was performed in order to plan and evaluate dental health care for a cohort of 67-year-olds in a Danish municipality. The purpose was to study general and dental health and the effect of life-style and social network relations. A total of 216 persons (71% of the persons selected) were interviewed in 1987; measurement of life-style was based on information about how often the respondents participated in social, cultural, and spare time activities. Family network activity was measured from information on the frequency of contact with family members, while data about relations with friends and neighbours were intended to measure the quality of contact. Moreover, the participants were asked about the presence of various symptoms of ill health, regular use of drugs, and dental symptoms. Additive indices on lifestyle and social networks were constructed. Symptoms were frequent among less active people; e.g. 36% of the participants with very low activity reported at least five complaints of ill health against 10% in the group with an active lifestyle. Among less active persons, 51% were edentulous, against 34% among active persons. Most symptoms of ill health occurred relatively often among persons with weak social networks. Ill health seems to be related to a passive lifestyle and non-supportive social network.

[Cross-sectional survey on the nutritional and life-style habits of secondary school students in Hungary].

INTRODUCTION: The national representative survey of secondary school students (age: 15-18 years) was undertaken between 1997 and 2000. The authors presented the data related to the nutritional and life-style habits. METHODS: The data for 6,347 students (48.4% boys and 51.6% girls) were evaluated. The anonymous questionnaire contained inquiries on nutritional rhythm, food frequency, use of vitamin and mineral supplements, smoking, alcohol and drug consumption habits, regular physical activity and family background (qualification, smoking, alcohol consumption). Within the frame of personal interviews the authors collected data on students' history with regard to occurrence of diabetes mellitus, other chronic diseases and in girls the time of the first menstruation. Concerning parents' history the authors collected information on the incidence of hypertension, myocardial infarction, diabetes mellitus, and stroke. STATISTICAL EVALUATION: Data were recorded in Data-Ease database system, in forms of individual records. The individual records were converted to be suitable for the statistical evaluation by SPSS for windows 9 statistical program pack. Data are presented as means and percent distribution. RESULTS: The nutritional rhythm of students was irregular. The daily consumption of milk, dairy products, fruits, fresh vegetables and vegetable dishes was insufficient. Eighty percent of students added extra salt to foods. More than 49% of students regularly consumed some forms of vitamin and/or mineral supplements. Thirty five percent of boys and 30% of girls smoked daily, 14.6% of boys and 5.9% of girls consumed alcohol at least once a week. Fifteen percent of boys and 11% of girls already tried taking drugs at least once. Only 50% of boys and 31% of girls were involved in a regular physical activity. Twenty two percent of fathers and 25% of mothers had university qualifications, whereas intermediate qualifications were recorded in 63 and 59%, lower qualifications occurred in 8 and 13% of parents, respectively. The incidence of smoking was 42% for fathers and 36% for mothers. Weekly alcohol consumption was recorded in 11%, daily consumption in 7% among fathers, the same figures for mothers were 4-4%, respectively. The incidence of hypertension, myocardial infarction, diabetes mellitus, and stroke was 26; 3.4; 5.4 and 1.5% in fathers and 32.9; 4.2; 6.6 and 1.5% in mothers. CONCLUSIONS: The data collected in the complex nutritional hygienic survey revealed serious deficiencies in the nutritional and life style habits of secondary school students. These factors considerably contribute to the unfavorable statistics of nutrition related non-infectious diseases in adulthood.

Prevalence of tobacco smoking among junior high school students in Japan and background life style of smokers.

In order to estimate the prevalence of tobacco smoking among junior high school students in Japan and to assess certain characteristics of smokers, the authors surveyed 5240 students aged between 12 and 15 years. In terms of both the number of subjects and of schools, this was the first major survey of Japanese junior high schools on the relationship between tobacco smoking and the background life styles of smokers. Of all students, 30.5% of males, 13.3% of females and 22.2% of the total were lifetime smokers; 3.3%, 0.8% and 2.2%, respectively, were daily smokers. As the frequency of tobacco smoking increased, the regularity of the life style routine was significantly more disturbed, and school and family life were significantly less relaxed. The authors suggest that the strengthening of family cohesion would be an effective preventive strategy in Japan.

Relationship of training and life-style to 16-km running time of 4000 joggers. The '84 Berne "Grand-Prix" Study.

To investigate running activity, life-style, and endurance capacity of joggers, all competitors of a popular 16-km race were surveyed by questionnaire. The response rate was 83.6%, yielding a study population of 4358 male runners over age 16. In univariate analysis, there were significant associations between 16-km running time and weekly training distance (average of 1 year), weekly training frequency, body mass index (BMI), age, cigarette smoking, years of regular running, and frequency of alcohol cosumption. A multiple regression analysis provided six significant, independent predictors of 16-km time, explaining 47% of its variance: weekly training distance (standardized regression coefficient = -0.46), age (0.37), BMI (0.23), years of regular running (-0.19), weekly training frequency (-0.11), and cigarette smoking (0.10). Based on laboratory treadmill testing of a subsample of runners, 16-km running times were transformed into maximum aerobic capacities (VO2 max equivalents) for all competitors. In comparison with the general population, even the slowest 5% of the runners showed a higher endurance capacity than the age-specific population mean. Application of the multivariate regression model for an estimation of the overall impact of training and life-style on endurance capacity showed that the great difference in mean endurance levels between joggers and the general population could entirely be attributed to differences in running activity, BMI, and smoking. We conclude that the joggers investigated were, on average, not selected concerning biological predisposition and genetic endowment since their behavior alone explained their high average endurance capacity.

Life-style related health promotion needs in oil refinery employees.

This report describes the screening procedure used in the assessment of health promotion needs in a group of oil refinery employees (n = 885). The aim of the study was to assess the life-style related health promotion needs before initiating an intervention programme study. The frequency of different health promotion needs and their distribution according to age, gender and employee group were examined, as well as the factors explaining different health promotion needs. The assessment was based on laboratory tests and questionnaires covering the target areas of physical activity and fitness, dietary habits, overweight, blood pressure, serum lipids, smoking, alcohol consumption, sleep, mental health, and musculoskeletal symptoms. Life-style related health promotion needs were frequent. Self-assessed health was strongly associated with health promotion needs in most of the ten target areas and also with the total number per person of areas with health promotion needs. Health promotion needs were also associated with such demographic variables as age, gender, basic education, and vocational training. If health promotion activities are provided to employees in a company, assessment of individual needs is necessary to find the employees with the greatest need of health promotion actions. This study presents one method of screening, although certain simplification is needed to make it fit into the daily routines. The contents of health promotion activities could also vary according to the differences related to age and gender observed in health promotion needs of the target population.

[Comparison of intensive and moderate individual life-style intervention programs for overweight or obese persons with fasting glucose levels of 95-125 mg/dl in Japan].

OBJECTIVES: There are considerable differences in individual health education programs for persons at high risk of type 2 diabetes between ordinary Japanese life-style modification programs and the Diabetes Prevention Program in the US, the former being relatively moderate and the latter more intensive. We therefore compared the effectiveness of intensive and moderate intervention, focusing on the frequency of individual educational classes. METHODS: The subjects were men and women aged 44-69 years living in Nishiaizu town, Fukushima prefecture in Japan. Their fasting plasma glucose concentration was between 95 and 125 mg/dl at health examinations conducted in 2002 or 2003. They also had a body mass index (BMI) of 23.0 or higher, a fasting plasma glucose concentration of 125 mg/dl or lower and a post-load plasma glucose concentration (2 h) of 199 mg/dl or lower in the 2004 survey. We assigned the subjects according to their residences to an intensive life-style intervention group (two education classes per month; n = 11) or a moderate intervention group (one education class per month; n = 14). The main outcome measure was the change in body weight after 6 months of intervention. RESULTS: The loss of body weight was -3.5 kg (P< .0001) in the intensive intervention group and -1.8 kg (P = 0.02) in the moderate group, and the net difference in body weight loss between the groups was -2.0 kg (95% confidence interval -4.0 to -0.05; P = 0.045) after adjustment for age, sex, and baseline body weight. BMI and subcutaneous fat area showed similar results. The post-load plasma glucose concentration (2 h) and other tested values showed no significant net change between the two groups. CONCLUSIONS: Intensive and moderate intervention both reduced body weight in overweight or obese persons at high risk of type 2 diabetes. The intensive intervention, two sessions of individual education classes per month, was significantly more effective than the moderate one for reducing body weight.

Traumatic events and life-style in ancient Italian populations.

Traumatic lesions are commonly found in archaeological skeletal samples and provide useful information about various behavioral and cultural aspects of the populations. Our aim was to evaluate the relationship between the distribution and types of skeletal traumatic lesions and the different life-styles of past populations. We examined three necropolises in central Italy. Pozzilli (VI-IV century BC) and Quadrella (I-IV century AD) are from the same geographical area (Molise) but belong to different periods; Novilara (IX-VI century BC) is located in Marche but belongs to the Iron Age like Pozzilli. The lesions observed at Pozzilli seem not to be accidental, whereas the traumas observed at Quadrella can be attributed to occasional, unintentional events. Cranial injuries observed at Novilara strengthen the hypothesis that the population was composed, at least in part, of warriors. Our results suggest the presence of a relationship between skeletal traumatic lesions and life-styles of populations.

Smoking in a public health agency: its relationship to sick leave and other life-style behavior.

A survey questionnaire was administered to employees of a public health agency regarding their involvement with smoking and other life-style behavior. Responses were analyzed and combined with sick leave data to determine the use of sick leave among employees who currently smoke, those who never smoked, and those who formerly smoked. Current smokers took significantly more sick leave than those who have never smoked ("nonsmokers") or former smokers. Using an analysis of variance model, only smoking status, education level, and sex, among selected demographic variables, were significantly related to the amount of sick leave taken. Current smokers took excess sick leave (amounting to nearly $40,000) as compared with nonsmokers and ex-smokers combined over a 21-month period. This study also characterizes the relationship between smoking status and selected life-style behavior. Smokers were less active, less likely to use seat belts, less likely to believe that smoking is related to health, and more likely to be heavier and to eat a poor diet than their nonsmoking or former smoking counterparts. We make suggestions regarding the reduction of smoking and other deleterious behavior as a means of controlling costs and reducing employee morbidity.

Life-style and environmental factors in the development of nasal NK/T-cell lymphoma: a case-control study in East Asia.

Cases of nasal NK/T-cell lymphoma (NKTCL) occur occasionally in Asian and Latin American countries but rarely in Western countries. The etiological role of life-style and environmental factors in nasal NKTCL was investigated. Five university hospitals in Japan and one each in Korea and China participated in this study; a total of 88 cases and 305 hospital controls were accrued during 2000-2005. The odds ratio (OR) of NKTCL obtained after adjustments of age, sex and country was 4.15 (95% confidence interval (CI), 1.74-9.87) for farmers, 2.81 (CI, 1.49-5.29) for producers of crops, 4.01 (CI, 1.99-8.09) for pesticide users, 11.65 (CI, 1.17-115.82) for residents near garbage burning plants, 2.95 (CI, 1.25-6.95) for former drinkers, and 0.49 (CI, 0.23-1.04) for current smokers. The ORs for crop producers, who minimized their exposure to pesticides by using gloves and glasses, and sprinkling downwind at the time of pesticide use, were 3.30 (95% CI, 1.28-8.54), 1.18 (95% CI, 0.11-12.13) and 2.20 (95% CI, 0.88-5.53), respectively, which were lower than those for producers who did not take these precautions. Exposure to pesticides and chemical solvents could be causative of NKTCL. Taken together, life-style and environmental factors might be risk factors for NKTCL.

Homocysteine and life-style in the elderly.

Elevated homocysteine increases the risk of vascular diseases but little information is available about this issue in the elderly. The aim of this cross-sectional study was to evaluate the relationships between homocysteinemia and gender, anthropometric, and life-style characteristics in a community-dwelling elderly population (65 men and 120 women; 67-78 years). Basal plasma homocysteine levels were determined by High Performance Liquid Chromatography (HPLC). Clinical records, and nutritional and anthropometric variables were collected in all subjects. Body composition was evaluated in all subjects by Dual energy X-ray Absorptiometry (DXA). Thirty-three percent of women and 66% of men had hyper-homocysteinemia. In women, a positive correlation was present between homocysteinemia, age, diastolic blood pressure and plasmatic creatinine, and a negative correlation between homocysteine, fiber intake and folates. In males, there was a positive correlation between plasma homocysteine, age, and body mass index. Multiple regression analysis showed that fat-free mass, cigarette smoking, fiber intake, vitamin B6 and total kcal intake accounted for 18% of homocysteine variance in males (R2 = 0.18, p<0.05). Significantly higher homocysteine values were found in women with a history of cardiovascular disease than in those without (16.6 +/- 9.4 vs 13.8 +/- 4.4 micromol/L, p<0.05). Homocysteinemia was significantly higher in elderly men compared to women (16.7 +/- 4.7 vs 15.3 +/- 7.6; p<0.05). Gender differences in homocysteine disappeared after adjusting for fat-free mass. This study confirms the age-related increase in plasma homocysteine. Life-style characteristics seem to influence significantly homocysteine levels in the elderly. Our study shows that gender effects on homocysteine may be attributed to differences in body composition.

An investigation of nutrition-related risk factors in an isolated Aboriginal community in northern Australia: advantages of a traditionally-orientated life-style.

Australian Aborigines develop a high frequency of type-2 diabetes mellitus when they make the transition from a traditional to an urban life-style. Preliminary studies were conducted at an outstation in northeastern Arnhem Land where the Aborigines have been exposed to Western influence for approximately 20 years only and where they continue to follow a life-style that is largely traditional. At the time of the study 31 persons were resident at the outstation, 20 persons were over 15 years of age (adults) and 11 persons were under 15 years of age (children). Eighteen adults and six children were tested. By standard criteria for body mass index these persons were all underweight (less than 20 kg/m2). In spite of this, they displayed no biochemical evidence of malnutrition. Their plasma fatty-acid profiles were consistent with a low dietary fat intake and a high consumption of lean meat. Levels of linoleic acid were much lower and those of arachidonic acid were much higher than are those in persons who consume a Western diet. Fasting glucose and cholesterol concentrations were low relative to those of urbanized Aborigines and white Australians. However, their fasting insulin and triglyceride levels were inappropriately high for their very low body mass index and fasting glucose levels. The mild elevation of triglyceride and fasting insulin levels is consistent with insulin resistance and suggests that these Aborigines (in common with other Aborigines) may become susceptible to obesity and diabetes if they became urbanized further.

EPIC-Italy cohorts and multipurpose national surveys. A comparison of some socio-demographic and life-style characteristics.

BACKGROUND: EPIC-Italy cohort study recruited subjects who voluntarily accepted to participate in the project. From the self-selected bases of the population sample, some bias could derive in the data interpretation when risk estimation for cancer disease related to life-style factors is the principal concern. Knowledge of the bias related to self-selected sampling is important for better directing the interpretation of the EPIC-Italy study results. METHODS: We investigated the characteristics of volunteer subjects recruited in the EPIC-Italy cohorts and compared them with those of the randomly selected subjects recruited in the Multipurpose ISTAT Surveys realized in the same period (1993-1998) in which the EPIC-cohorts were recruited. RESULTS: We found some differences, and in particular a different attitude towards cigarettes smoking and wine consumption, between the EPIC cohort and the Multipurpose ISTAT Surveys, as well as among geographical areas within the EPIC cohort. CONCLUSIONS: The uneven distribution of some characteristics suggests that the self-selected subjects were characterized by an overall lower consumption of wine and cigarette smoking even when the educational level was considered. This could suggest a generally more healthy life-style among subjects recruited on a volountary bases.

Life-style and other characteristics of radiation workers at nuclear facilities in Japan: base-line data of a questionnaire survey.

To examine confounding on the risk assessment of the radiation workers at nuclear facilities in Japan, a questionnaire survey of their characteristics such as life-style and occupational history was performed for 54,369 male and 470 female workers who were currently engaged in the job and valid answers were obtained from 48,281 males and 428 females. In order to know whether these characteristics were different among different dose groups, the Mantel extension statistical test was performed only for male respondents, with cumulative radiation doses stratified into 5 classes. Increasing trend according to the increasing doses was statistically significant for the percentages of tobacco smokers and of heavy smokers. It was also the case for heavy alcohol drinkers. Percentages of workers who were engaged in jobs dealing with specific toxic materials were also increasing in the higher dose groups. On the other hand, percentage of workers who underwent the X-ray examination of the upper digestive tracts or other radiological examinations tended to be lower in higher dose groups. These results indicate that characteristics of radiation workers such as life-style are different among dose groups and thus may play a role as a confounding factor in the statistical relation between the radiation doses and cancer mortalities.

Life-style changes and coronary heart disease: the influence of nonpharmacologic interventions.

Life-style habits such as diet and exercise can have powerful affects on the development and progression of coronary heart disease. This article presents evidence supporting the use of these two modalities in the treatment of coronary heart disease. Diet is discussed in terms of cholesterol, obesity, fiber, fish oils, and antioxidants. Exercise is discussed in terms of the preparation for and the components of an exercise program. Appropriate nursing interventions are offered for use when working with patients who must modify their dietary or exercise habits.

Increasing overweight in Greenland: social, demographic, dietary and other life-style factors.

OBJECTIVES: In several Arctic countries, weight gain is very evident among the local populations and the percentages of overweight and obese persons are increasing rapidly. Since the development of overweight among the Arctic populations seems to coincide with the westernization of their diet and other life-style factors, it is tempting to hypothesize that the transition to carbohydrate- and fat-rich western food causes the weight gain. The high relative content of (n-3) fatty acids in traditional foods presumably provides some protection against cardiovascular diseases, type 2 diabetes and various other diseases of affluent industrialized societies. In the present study, we have investigated the recent weight gain in Greenland and have tried to relate it to social factors, present dietary habits and other life-styles. STUDY DESIGN: The cross-sectional study, which was part of the Arctic Monitoring and Assess Programme, included 410 men and women (18-49 years) from 5 districts in Greenland. It was based upon questionnaires including a dietary survey, anthropometric measurements and blood lipid analyses. RESULTS: Obesity (Body Mass Index (BMI) > 30 kg/m2, corresponding to about 19% of the participants) increased with age, was most prevalent among higher household economic levels, and correlated with neither local, nor imported food intake. CONCLUSION: Overweight was not found to be correlated with either western, or traditional food composition. Obesity had adverse effects on several health indicators, serum triglyceride, HDL and the cardiovascular risk index, (Chol-HDL)/HDL and TG/HDL, counteracting the positive effects of (n-3) fatty acids and should be considered as a serious health risk for the Greenlandic population.

Bone density, biochemistry and life-style.

We have assessed the relationship between bone density, biochemistry and life-style factors in a cross-sectional study of 434 pre- and 357 postmenopausal women. Bone-mineral content (BMC) was measured in the non-dominant forearm using single-photon densitometry. Bone mass was corrected for bone size (BMC2) in a sub-set of 263 subjects. Correlation statistics and multiple regression analyses were used to identify physical and biochemical measurements that could be used to best predict BMC or BMC2. These were combined with lifestyle factors, using multiple logistic regression analysis, to identify women at risk of low bone density. Cut-off values were taken as the 5th percentile of the bone density distributions in pre-menopausal women. In postmenopausal women, using BMC2 values to define "risk", and using age, creatinine, alkaline phosphatase, thyroxine treatment, and calcium supplementation as predictors, a sensitivity of 73% and a specificity of 95% were achieved. Such a model may be of use as a "first pass" screening test for osteoporosis.

[Life style, Chlamydia trachomatis infection, bacterial vaginosis and their impact on the frequency of cervical lesions].

OBJECTIVES: Sexually transmitted infectious factors attained unquestionable importance in the initiation of the cervical intraepithelial neoplasia. The aim of this study was to evaluate the incidence and impact of Bacterial vaginosis, Chlamydia trachomatis infection in accordance to a life style on clinically and cytologically evaluated cervical lesions. DESIGN/METHODS: Seventy-two young women without any symptoms were included to the study. Women underwent pelvic examination when cervical smears for cytology and Ch.tr. were taken and BV tests were performed. Presence of Chlamydia was estimated by direct immunofluorescent method. Subjects included to the study provided information concerning life style, and gynecological complaints. RESULTS: In both BV(+) or Ch.tr.(+) women, abnormal PapTest results were more frequently observed. All those three factors correlated with declared over 5 lifetime sexual partners. Ch.tr. infection correlated with BC pills using, cigarette smoking and presence of the cervical lesions evaluated as glandular ectopy. Abnormal PapTest result was obtained in 12 subjects. Two, the most abnormal cases were described as LSIL and confirmed by direct biopsy as CIN 1, also with coexistence of C. trachomatis infection and positive for BV. CONCLUSIONS: Ch.tr. infection seems to affect more frequently sexually active, smoking, young women using BC pills, with presence of cervical lesion described as clinically unsuspected glandular ectopy, although with occasionally cytological abnormal findings.
