How Stress Is Related to Age, Education, Physical Activity, Body Mass Index, and Body Fat Percentage in Adult Polish Men?

Stressful events and chronic tension are considered a burden and a threat to physical, mental, and social health. The aim of the study was to demonstrate the associations of variation in stress exposure with social factors, physical activity, basic components of physical fitness, body mass index (BMI) and percentage of body fat (BFP). An additional objective was to identify the main BFP modifiers among those analyzed. The material consisted of data of ethnically homogeneous group 355 men (32-87 yrs), invited to the study as part of the Wroclaw Male Study research project. The analyzed features included socioeconomic status (age, educational level), elements of lifestyle (physical activity), major and most important stressful life events-Social Readjustment Rating Scale (SRRS) and basic parameters of the somatic structure of the body (BMI, BFP). Statistical analyses included: chi-square test, Mann-Whitney U test and backward stepwise regression (significance level α = 0.05). Stress exposure showed significant socioeconomic variation among the adult Poles studied. Higher levels of education were associated with higher levels of stress. Significant correlations between SRRS and physical activity were found, especially in men older than 60 years and with higher levels of education. A positive relationship was shown between SRRS and BFP, especially in men under 60 years of age. BFP appeared to depend mainly on age and stress. The main determinants of SRRS were age and education level, while BFP turned out to be more sensitive to stress than BMI. The modifying force of physical activity for SRRS appears to be age dependent.

Age, Education, and Stress Affect Ageing Males' Symptoms More than Lifestyle Does: The Wroclaw Male Study.

An increasing number of subjects are affected by health problems related to the advanced involutional processes. It is extremely important to identify the determinants of the rate of occurrence of physiological, psychological, and social manifestations of aging. The aim was to determine how factors such as lifestyle, level of education, or severity of stressful life events indicate the appearance of aging symptoms in adult men. The material consisted of data of ethnically homogeneous group of 355 men (32−87 years), invited to the study as a part of the Wroclaw Male Study research project. The analyzed features included (1) socioeconomic status: age, educational level, marital status, and having children; (2) elements of lifestyle: alcohol drinking, cigarette smoking, and physical activity; (3) major and most important stressful life events­the Social Readjustment Rating Scale; (4) symptoms related to male aging­the Aging Males' Symptoms. The backward stepwise regression models, the Kruskal−Wallis test, and multiple comparisons of mean ranks were used. Noncentrality parameter δ (delta), two-tailed critical values of the test, and test power with α = 0.05 were calculated. Among the analyzed variables, age was most strongly associated with the intensity of almost all groups of andropausal symptoms in men (p = 0.0001), followed by the level of education (p = 0.0001) and the intensity of stressful life events (p = 0.0108). Selected lifestyle elements turned out to be much less important (p > 0.01). Preventive actions aimed at slowing down the intensification of involutional processes, including teaching strategies for coping with stressful life events, should be implemented in groups of men with specific risk factors from an early age.

The relationship between: occupational status, biological condition and androgen hormone level among Polish adult men: the Wroclaw Male Study.

Population health and its determinants are one of the major challenges to social and economic policy. The aim of this study was to investigate the relationship between occupational activity and biological condition in adult working Polish men. The participants of the study were 300 men (30-65 years), healthy inhabitants of the city of Wroclaw, Poland. Seventeen measures of biological condition were examined. The subjects were divided into three different occupational groups: professionals, soldiers and skilled workers. A comparison of biological age profiles of three occupational groups showed that in the majority of characteristics, professionals had the youngest biological age, whereas skilled workers had the highest biological age. The results for soldiers were not as unambiguous, but biological parameters were generally closer to those for professionals. Inborn biological predispositions and long-term impact of the working environment can influence on the biological condition of various professional groups. Knowledge of the determinants of biological condition might result in efficient use of predisposition to work or may be of help in extending their time of work ability.

Self-reported versus measured body height and weight in Polish adult men: the risk of underestimating obesity rates.

BACKGROUND: In some epidemiological studies, self-reported height and weight are often used to save time and money. Self-reported height and weight are commonly used to assess the prevalence of obesity. The aim of this study was to assess the differences between self-reported and measured height and weight in adult men, and to determine how the accuracy of self-reported data depended on age and education. The prevalence of obesity was also calculated based both on self-reported and measured data. MATERIAL AND METHODS: Data were collected during two population studies carried out in Wroclaw in 2010. One study included 1,194 19-year-old males who reported for the health examination mandated by the National Conscription Board (younger group). The other group included 355 men between 35 and 80 years old who reported for a ten-year follow-up (older group). Data were analyzed separately for both age groups. RESULTS: Both younger and older subjects overestimated their height by 1.4 cm and 1.0 cm (1.4 cm, 95 % CI: 1.26, 1.51, and 1.0 cm, 95 % CI: 0.85, 1.26, respectively). On average, younger subjects overestimated their weight by 0.7 kilograms (95 % CI: 0.55, 0.92), whereas older subjects underestimated their weight by 0.9 kilograms (95 % CI: -1.15, -0.48). The lower the level of education, the more the subjects overestimated their height. CONCLUSIONS: Adult men systematically overestimate their height and underestimate their weight. The magnitude of the inaccuracy depends on level of education. When self-reported data are used, the prevalence of obesity is generally underestimated. Using self-reported data to calculate BMI can lead to a substantial underestimation of the proportion of underweight and obese individuals in a population. Finally, using self-reported values for height in studies on social inequality may lead to false conclusions.Background: In some epidemiological studies, self-reported height and weight are often used to save time and money.

Secular trends in body height and body mass in 19-year-old Polish men based on six national surveys from 1965 to 2010.

OBJECTIVES: The aim was to determine whether an intergenerational trend toward increased stature is slowing down, and whether body weight has recently increased among young men in Poland, as it has in Western European countries. METHODS: Data were taken from six national surveys of 19-year-old Polish male conscripts from cohorts 1965, 1976, 1986, 1995, 2001, and 2010. RESULTS: The mean stature of this population increased throughout the last 45 years from 170.5 cm in 1965 to 178.3 in 2010. However, the average gain in stature per decade declined from 2.4 cm in the period 1965 to 1976 to 0.8 cm per decade in 1995 to 2001, but increased to 1.0 cm in the last period. The average of body weight increased from 63.2 kg in 1965 to 73.1 in 2010 and body mass index (BMI) rose from 21.73 to 22.94 in the same period. The tempo of increase varied in different periods; between 1965 and 1986 an insignificant increase was observed (of circa 0.12); in 1986 to 1995 there was no increase, whereas the period of 2001 to 2010 witnessed a significant increase (of circa 0.76). CONCLUSIONS: The trend of body size and stature increase within the Polish population, although decelerating, remained positive and steady during the last 45 years. No significant impact of the past half-century's socioeconomic crises was observed in these measures of growth. We concluded that during the economic crises some effective mechanism protecting the living conditions of the children and youth were operating within the population.

Secular trends in BMI and the prevalence of obesity in young Polish males from 1965 to 2010.

BACKGROUND: Obesity is a serious public health problem, the prevalence of which is increasing dramatically all over the world. The aim of this study was to examine trends in body mass index (BMI) and the proportion of overweight and obese individuals among 19-year-old Polish males reporting for mandatory military fitness exams from 1965 to 2010. METHODS: Height, weight and BMI [weight (kg)/height (m(2))] in five 10% nationwide random samples of 19-year-old conscripts examined in 1965, 1986, 1995, 2001 and 2010 were analysed. RESULTS: From 1965 to 2010, mean BMI in 19-year-old Polish males increased from 21.7 to 22.9. The rate of change was not uniform, with a rapid increase in mean BMI from 1995 to 2010. Beginning in 1965, the proportion of men with a BMI over 25 has been steadily increasing from one decade to the next, and was four times higher in 2010 than it was in 1965. The rate of increase per decade was twice as high from 2001 to 2010 than it was from 1995 to 2001. In 2010, only 70.8% of young men were of ideal weight. CONCLUSION: Increase in obesity can be attributed to the social and economic changes brought about by the transformation of the country from a communist to a free-market economy in 1989. The challenges of the obesity epidemic for public health services and its impact on morbidity and life expectancy are also discussed.

[Regional differences in premature mortality in Poland]. / Terytorialne zróznicowanie przedwczesnej umieralnosci w Polsce.

The aim of the study was to investigate the regional and social differences in men and women premature mortality. Individual death data for men and women aged 25-64 were obtained from the national mortality database of the Central Statistical Office (CSO). As the data on living Polish adults were available only from the National Population Census, which took place in Poland in 2002 (National Population and Housing Census 2002). The measure of mortality used in this analysis was the sex-, age-, education-specific rate of mortality. The higher mortality rate was observed in the western, north-western and south-western voivodeships. In the Lublin Voivodeship the level of premature mortality was the highest in Poland. The highest mortality of rural men was in the north-eastern, south-western and central regions of Poland, whereas higher mortality rates than average of rural women were in four voivodeships from different parts of Poland. The largest social inequalities in premature mortality was found in Lublin Voivodeship, especially sharp social contrasts were observed in towns. Wider social gaps in mortality than average was discovered for men in Masovian and Lower Silesian Voivodeships and Opole Voivodeship for women. Knowledge about regional differences in mortality helps to construct the adequate preventive programs.

Decrease in sex difference in premature mortality during system transformation in Poland.

In recent years, sex differences in mortality have followed diverse patterns of change in developed countries. As there is no analogous evidence from Poland, the aim of this study was to describe the pattern of change in excess male mortality among Polish inhabitants aged 35-64 during 1995-2002, when the major socioeconomic transformation occurred, and compare it with sex differences in mortality observed in the late 1980s. During the study period, excess male mortality decreased significantly, independently of age and educational level. The reduction in mortality was observed in both sexes, but its magnitude was greater in men. These changes resulted mainly from a reduction in mortality rates due to cardiovascular disease and lung cancer in males and a concomitant increase in mortality rates due to lung cancer and suicides in females. Although, in general, excess male mortality decreased, social gradients related to this phenomenon increased. Subjects (in particularly men) who had graduated from university benefited the most, their magnitude of reduction in mortality rates being the greatest. Changes in social environment during the transformation period in Poland are suggested as major determinants of these changes, but further studies are needed.

Social inequality in premature mortality among Polish urban adults during economic transition.

Rates of premature mortality among adults are important measures of the economic and psychosocial well-being of human populations. In many countries, such rates are, as a rule, inversely related to the level of attained education. We examined changes in educational group-specific mortality rates among urban adults in Poland during the country's rapid transition in the 1990s from a socialist command economy to a free market system. Two census-based analyses of individual death records of urban dwellers aged 35-64 years were compared. We utilized all records of death, which occurred during the 2-year periods 1988-89 and 2001-02. Population denominators were taken from the censuses of 1988 and 2002. The age-specific mortality rates were used to evaluate absolute differences in mortality. To assess relative differences between educational levels, mortality rate ratios (MRRs) with 95% CI (confidence interval) were calculated using Poisson regression. A regular educational gradient in mortality persisted in each 10-year age group throughout the period covered by our data. Moreover, age-specific mortality rates declined steadily in all educational groups, and this decline was most marked in the two oldest age groups (45-54 and 55-64 years). The trend was accompanied by widening of educational differences in mortality as expressed by MRRs. Systemic political transformation in Poland has brought a mixture of beneficial and detrimental effects on the well-being of society. With regard to the changes in rates of premature mortality among adults, the benefits have prevailed, although individuals with the lowest educational level benefited less than those with the highest education.
