No association between history of psychiatric treatment and postoperative weight reduction after bariatric surgery

PURPOSE

The objective of the study was to assess whether the history of psychiatric treatment was associated with (1) body weight and BMI on admission for bariatric surgery, (2) weight loss > 5 kg prior to bariatric surgery, and (3) postoperative body weight reduction.

METHODS

Data from medical records of all consecutive patients admitted for surgical treatment of obesity in the 2nd Department of General Surgery Jagiellonian University Medical College were obtained. There were 1452 records of patients who underwent bariatric surgery between 2009 and 2021 included in the study.

RESULTS

History of psychiatric treatment was found in 177 (12%) of the sample and was inversely associated with body weight and BMI on admission for surgery in women. Men with history of psychiatric treatment were 54% less likely to lose > 5 kg before the surgery (OR = 0.46 95% CI = 0.24-0.88). Both in men and women %TWL did not differ significantly by history of psychiatric treatment (Me: 40.7 vs. 45.9; p = 0.130 and Me: 27.0 vs. 23.9; p = 0.383, respectively). After adjustment for covariates no association was found between history of psychiatric treatment and body weight reduction one year after surgery.

CONCLUSION

Although men with preoperative history of psychiatric treatment had lower odds of losing weight before the surgery, psychiatric treatment did not differentiate the effectiveness of bariatric treatment in 1 year of observation. Bariatric surgery appears to be an effective obesity care for people treated for mental disorders.

Determinants of body weight changes during COVID-19 pandemic in older urban residents

INTRODUCTION

COVID‑19 pandemic is associated with unfavorable body weight changes. However, little is known about these changes in older individuals, a particularly vulnerable group with limited representation in both direct and online research.

OBJECTIVES

The aims of the study were to assess changes in body weight and determinants of thesechanges, and to evaluate the prevalence of COVID‑19 history and its impact on the changes in body weight in older individuals.

PATIENTS AND METHODS

The analysis included 2076 residents of Kraków, aged 60 to 84 years. Data on sociodemographic factors, lifestyle, history of COVID‑19, and changes in body weight were collected in 2021 and 2022 by a postal survey. Multinomial logistic regression analysis was used.

RESULTS

COVID‑19 tests were performed in 29.3% of the participants, with one‑third of them being positive. A total of 14.3% of the participants had any history of COVID‑19. Almost two‑thirds of the study participants declared no change in their body weight during the pandemic, while 26.2% gained weight. The weight gain was associated with unfavorable sociodemographic and lifestyle conditions. Weight loss was reported by 11.3% of the participants, and it was associated with poor perceived health and a history of COVID‑19. After adjusting for covariates, the history of COVID‑19 was associated with about 4 times higher odds of weight loss in any case (odds ratio [OR], 2.69; 95% CI, 1.59-4.57 for nonhospitalized, and OR, 18.96; 95% CI, 5.64-63.73 for hospitalized individuals).

CONCLUSIONS

Most people with a change in their body weight gained weight due to unfavorable lifestyle modifications, but the history of COVID‑19, especially hospitalization, was a strong determinant of body weight loss.

ATHLOS Healthy Aging Scale score as the predictor of all-cause mortality in Poland and Czechia

Background

The ATHLOS consortium (Aging Trajectories of Health–Longitudinal Opportunities and Synergies) used data from several aging cohorts to develop a novel scale measuring healthy aging comprehensively and globally (ATHLOS Healthy Aging Scale). In the present study, we assessed the predictive performance of the ATHLOS Healthy Aging Scale for all-cause mortality in middle-aged and older adults.

Methods

Data from the Polish and Czech HAPIEE (Health Alcohol and Psychosocial factors In Eastern Europe) prospective cohorts were used. There were 10,728 Poles and 8,857 Czechs recruited. The ATHLOS Healthy Aging Scale score was calculated for all participants using data from the baseline examination carried out from 2002 to 2005. The follow-up for all-cause mortality was completed over 14 years. The associations between quintiles of the ATHLOS Healthy Aging Scale and all-cause mortality were estimated using Cox proportional hazards models.

Results

A total of 9,922 Polish and 8,518 Czech participants contributed ATHLOS Healthy Aging Scale and mortality data with 1,828 and 1,700 deaths, respectively. After controlling for age, the ATHLOS Healthy Aging Scale score was strongly associated with mortality in a graded fashion for both genders and countries (hazard ratios for lowest vs. highest quintile were 2.98 and 1.96 for Czech and Polish women and 2.83 and 2.66 for Czech and Polish men, respectively). The associations were only modestly attenuated by controlling for education, economic activity, and smoking, and there was further modest attenuation after additional adjustment for self-rated health.

Conclusion

The novel ATHLOS Healthy Aging Scale is a good predictor of all-cause mortality in Central European urban populations, suggesting that this comprehensive measure is a useful tool for the assessment of the future health trajectories of older persons.

Occurrence of Urinary Tract Infections and Physical Functioning in Patients After Stroke

Introduction: The majority of brain strokes result in a reduction of physical functioning and remain a major cause of disability. Post-stroke rehabilitation aims to improve physical functioning of patients who have suffered from stroke. Infections, including those of the urinary tract (UTI), are complications of stroke that occur in patients who undergo physical therapy at stationary departments of neurological rehabilitation and may significantly influence its effectiveness. Study aim: The main objective of the study is to assess the relationship between the UTI and physical functioning in patients after stroke, and the relationship between prevalence of UTIs and the results of rehabilitation in post-stroke patients. Material and methods: An observational case-control study was conducted, with a natural selection into the study groups according to the prevalence of UTI. Data was collected from the medical records of all stroke patients rehabilitated at the inpatient Neurological Rehabilitation Department of ORNR “Krzeszowice” in Krzeszowice during the period from 01 Jan. 2012 to 31 Dec. 2014. The study included 400 patients. Physical functioning was assessed using the Barthel and Rankin scales. Results. UTI occurred in 37.5% of patients. In the univariate analysis, the occurrence of UTIs was associated with worse physical functioning at admission and discharge. After adjustment to the influence of gender, age, side and type of stroke, the time since discharge from the stroke unit, the presence of diabetes and use urinary catheter, better physical functioning at admission to the neurological rehabilitation unit was inversely related to the occurrence of UTI (according to the Barthel scale: OR = 0.89, 95% CI: 0.85-0.94); according to the Rankin scale: OR = 1.75; 95% CI: 1.33-2.32). At discharge, after adjustment for: influence of physical functioning at admission to the ward and other confounding factors, the occurrence of UTI was not significantly correlated with the physical functioning of patients. During hospitalisation, physical functioning improved in both groups, but among the group of patients with UTI, the dynamics of the change was significantly greater than in patients without UTI. Conclusions. In stroke patients referred to inpatient neurological rehabilitation, UTIs are a common complication. The occurrence of UTI was associated with decreased physical functioning at admission to the department, but in patients with UTI, more dynamic improvement in physical functioning was found during rehabilitation. The incidence of UTI was not related to physical functioning at discharge from the ward.

Changes in Socioeconomic Status as Predictors of Cardiovascular Disease Incidence and Mortality: A 10-Year Follow-Up of a Polish-Population-Based HAPIEE Cohort

Although the inverse association between socioeconomic status (SES) and cardiovascular disease (CVD) is well established, research on the effect of changes in the SES throughout life on CVD risk in populations with different social backgrounds remains scarce. This study aimed to assess the relationship between childhood SES, adulthood SES, and changes in SES over time, and CVD incidence and mortality in a Polish urban population. In addition, the predictive performance of the SES index was compared with education alone. A cohort study with a 10-year follow-up was conducted, in which a random sample of 10,728 residents in Kraków aged 45-69 years were examined. The SES was assessed at baseline using data on education, parents' education, housing standard at the age of 10 years, professional activity, household amenities, and difficulties in paying bills and buying food. SES categories (low, middle, and high) were extracted using cluster analyses. Information on new CVD cases was obtained from questionnaires in subsequent phases of the study and confirmed by reviewing clinical records. Data on deaths and causes were obtained from the residents' registry, Central Statistical Office, and the participants' families. The effect of the SES index on the risk of CVD was assessed using Cox proportional hazard models. In male and female participants, the CVD incidence and mortality were observed to be 27,703 and 32,956 person-years (384 and 175 new CVD cases) and 36,219 and 40,048 person-years (159 and 92 CVD deaths), respectively. Childhood SES was not associated with CVD incidence and mortality. A protective effect of high adulthood SES against CVD mortality was observed in men and women (HR = 0.59, 95% CI = 0.31-0.97; HR = 0.33, 95% CI = 0.14-0.75, respectively). In women, downward social mobility was related to 2.24 and 3.75 times higher CVD incidence and mortality, respectively. In men, a protective effect against mortality was observed in upward mobility (HR = 0.50, 95% CI = 0.29-0.84). Model discrimination was similar for the SES index and education alone for the association with CVD incidence. In women, the SES index was a slightly better predictor of CVD mortality than education alone (C-index = 0.759, SE = 0.0282 vs. C-index = 0.783, SE = 0.0272; p = 0.041). In conclusion, high adulthood SES, but not childhood SES, may be considered to be a protective factor against CVD in urban populations in high-CVD-risk regions. No effects of critical periods in early life were observed on CVD risk. In later life, social mobility was found to affect CVD mortality in both men and women. In men, a protective effect of upward mobility was confirmed, whereas in women, an increased CVD risk was related to downward mobility. It can be concluded that CVD prevention may be beneficial if socioeconomic potentials are strengthened in later life.

ATHLOS Healthy Ageing Scale score as the predictor of mortality in Poland and the Czech Republic

Background

A novel tool to measure healthy ageing was developed by the ATHLOS consortium (Ageing Trajectories of Health-Longitudinal Opportunities and Synergies). ATHLOS Healthy Ageing Scale, constructed using harmonized data from 16 independent ageing cohorts, was designed to contribute to worldwide research on healthy ageing. The aim of the analysis was to assess the relation between ATHLOS Healthy Ageing Scale and all-cause mortality in Central European populations.

Methods

Participants of the Polish and Czech HAPIEE cohorts (baseline age 45-69 years) were followed for 14 years. ATHLOS Healthy Ageing Scale was based on over 40 health indicators related to intrinsic capacity and functional ability. Cox proportional hazards models were used to determine the relationship between the ATHLOS Healthy Ageing Scale scores and all-cause mortality.

Results

As many as 9,922 Polish and 8,518 Czech participants had non-missing data on the ATHLOS Healthy Ageing Scale score and mortality (1828 and 1700 deaths, respectively). After adjustment for age, dose-response associations with mortality in both genders and countries were found (HR for lowest vs. highest quintile of the ATHLOS Healthy Ageing Scale: 2.98 and 1.96 in Czech and Polish women and 2.83 and 2.66 in Czech and Polish men, respectively). Only modest attenuation was observed when additionally adjusted for education, economic activity, smoking and self-rated health.

Conclusions

The ATHLOS Healthy Ageing Scale was found to be a good predictor of all-cause mortality in urban populations of Poland and Czechia. This composite indicator seems to be an important contributor to a better assessment of healthy ageing.

Association between soft drink, fruit juice consumption and obesity in Eastern Europe: cross-sectional and longitudinal analysis of the HAPIEE study

BACKGROUND

Fruit juice and soft drink consumption have been shown to be related to obesity. However, this relationship has not been explored in Eastern Europe. The present study aimed to assess the cross-sectional and longitudinal relationships between fruit juice, soft drink consumption and body mass index (BMI) in Eastern European cohorts.

METHODS

Data from the Health, Alcohol and Psychosocial factors in Eastern Europe population-based prospective cohort study, based in Russia, Poland and the Czech Republic, were used. Intakes of sugar-sweetened beverage (SSB), artificially-sweetened beverage (ASB) and fruit juice were estimated from a food frequency questionnaire. Participant BMI values were assessed at baseline (n = 26 634) and after a 3-year follow-up (data available only for Russia, n = 5205).

RESULTS

Soft drink consumption was generally low, particularly in Russia. Compared to never drinkers of SSB, participants who drank SSB every day had a significantly higher BMI in the Czech [β-coefficient = 0.28; 95% confidence interval (CI) = 0.02-0.54], Russian (β-coefficient = 1.38; 95% CI = 0.62-2.15) and Polish (β-coefficient = 0.83; 95% CI = 0.29-1.37) cohorts. Occasional or daily ASB consumption was also positively associated with BMI in all three cohorts. Results for daily fruit juice intake were inconsistent, with a positive association amongst Russians (β-coefficient = 0.75; 95% CI = 0.28-1.21) but a negative trend in the Czech Republic (β-coefficient = -0.42; 95% CI = -0.86 to 0.02). Russians participants who drank SSB or ASB had an increased BMI after follow-up.

CONCLUSIONS

Our findings support previous studies suggesting that soft drink consumption (including SSBs and ASBs) is positively related to BMI, whereas our results for fruit juice were less consistent. Policies regarding these beverages should be considered in Eastern Europe to lower the risk of obesity.

Relationship between the dietary glycemic load of the adult Polish population and socio-demographic and lifestyle factors - results of the WOBASZ II study

BACKGROUND

Cardiovascular disease (CVD) occurs more often among people with a low sociodemographic status, so it is worth knowing if any sociodemographic factor also has an impact on diet quality, defined by glycemic load (GL).

OBJECTIVES

Assessment of the relationship between the sociodemographic and lifestyle factors, health status self-assessment and dietary GL of the adult Polish population based on WOBASZ II study results.

MATERIAL AND METHODS

The study included a representative group of the Polish population aged ≥20 years (2,554 men and 3,136 women). A 24-hour dietary recall was collected to assess the dietary intake. The total GL was calculated by summing the GL values of the consumed food.

RESULTS

The average GL/1,000 kcal was significantly higher in women's than in men's diets (74.0 ±15.9 vs 71.2 ±15.7). Dietary GL/1,000 kcal increased with age (men: aged <35 - 70.3 and aged ≥65 - 73.9, women: 73.5 and 76.5, respectively). The lowest dietary GL/1,000 kcal was found among people living in large population centers. Dietary GL/1,000 kcal decreased with education level (men with primary, secondary and higher education: 73.4, 69.5 and 68.9, respectively, and women: 76.7, 73.4 and 70.9, respectively). Dietary GL decreased as an income increased. The highest GL/1,000 kcal was observed in the diets of participants who performed less physical activity. The highest GL/1,000 kcal was observed in the participants who defined their health status as very poor/poor and the lowest among those who defined their health status as good/very good.

CONCLUSIONS

Nutritional education about the proper selection of products that are sources of carbohydrates in the diet should be addressed mainly to people with low sociodemographic status, such as: people in the older age group, living in small population centers, and with lower levels of education and lower income. It should also be directed to people with a lower level of physical activity. Greater awareness of the choices of carbohydrate products is recommended to improve diet quality in these groups of people.

Dietary acid load and cardiometabolic risk in the Polish adult population

BACKGROUND

The potential influence of disorders of acid/base homeostasis on cardiovascular risk factors has been suggested.

OBJECTIVES

The aim of the study was to estimate the relationship between dietary acid load and the prevalence of cardiovascular disease and the prevalence and intensity of cardiovascular risk factors (i.e., hypertension, diabetes, overweight and obesity, dyslipidemia) in the Polish adult population.

MATERIAL AND METHODS

Data was derived from a cross-sectional survey of a random sample of 6,170 Polish residents aged 20+ (Multi-Center National Population Health Examination Survey, WOBASZ II study), including anthropometric and laboratory measurements, and estimates of nutrient intakes by 24-h recall. Dietary acid/ base load was assessed as potential renal acid load (PRAL) and net endogenous acid production (NEAP).

RESULTS

The median PRAL and NEAP values for the whole study population were: PRAL -3.85 mEq/day and NEAP 39.79 mEq/day. The prevalence of overweight and obesity, both in males and females, tended to decrease across tertiles of PRAL and to increase across tertiles of NEAP. In females, the values of several metabolic characteristics differed across tertiles of NEAP. After adjustment for age and waist circumference, these relationships did not persist, but the prevalence of diabetes was found to increase across tertiles of PRAL (p for trend <0.05) in females.

CONCLUSIONS

The dietary acid load in the Polish adult population was relatively low. There was no independent relationship between dietary acid load and cardiovascular disease and its risk factors in the population under study, except for the positive association between the PRAL value and diabetes prevalence in females.

Metabolic syndrome and its components in Polish women of childbearing age: a nationwide study

BACKGROUND

Abnormal body mass and related metabolic disorders may affect female reproductive health. The purpose of the study was to determine the prevalence of underweight, overweight, obesity, lipid and glucose metabolism disorders, hypertension, and metabolic syndrome, among Polish women of childbearing age.

METHODS

One thousand five hundred eighty-eight non-pregnant Polish women of childbearing age (20-49 years) who participated in the Multi-Centre National Population Health Examination Survey (WOBASZ II study) in 2013-2014, were assigned to 3 age groups: 20-29 years (n = 403), 30-39 years (n = 600) and 40-49 years (n = 585). Measurements of weight, height, waist circumference, blood pressure, blood lipids, and blood glucose were taken. For statistical analysis, the Kruskal-Wallis, Chi-Square, and Cohran-Armitage tests were used.

RESULTS

Of the participants, 4.3% were determined to be underweight, 25.2% were overweight, 15% were obese, and 53.1% had abdominal obesity. With age, the prevalence of both excessive body mass and abdominal obesity tended to increase, and that of underweight to decrease. Frequency of hypercholesterolemia and hypertriglyceridemia found in the whole group were 50% and 12.6% respectively, and also tended to rise with age. Low serum HDL-cholesterol (high density lipoprotein cholesterol) levels were found in 15.1% of the participants. Prevalence of impaired fasting glucose in the whole group was 8.2% and tended to increase with age. Diabetes was found in 1.2% of the participants and its prevalence also tended to rise with age, at the borderline of significance. Frequency of arterial hypertension and metabolic syndrome in the whole group was 15.7% and 14.1% respectively and both tended to increase with age.

CONCLUSIONS

Overweight and obesity, especially of abdominal type, and the related metabolic abnormalities are common in Polish women of childbearing age. Their prevalence tends to increase with age. Underweight is relatively common in the youngest age group.

Dietary polyphenol intake and risk of hypertension in the Polish arm of the HAPIEE study

Purpose

Dietary polyphenols have been studied for their potential effects on metabolic disorders, but studies on risk of hypertension are scarce. This study aimed to test the association between total and individual classes of dietary polyphenols and incidence of hypertension in the Polish arm of the Health, Alcohol and Psychosocial factors In Eastern Europe (HAPIEE) study.

Methods

A total of 2725 participants free of hypertension at baseline were tested for blood pressure or taking hypertensive medication within the last 2 weeks at 2–4-year follow-up visit. A 148-item food frequency questionnaire and the Phenol-Explorer database were used to estimate dietary polyphenol intake. Odds ratios (ORs) and 95% confidence intervals (CIs) of hypertension comparing the various categories of exposure (total and individual classes of polyphenol intake) with the lowest one (reference category) were calculated by performing age- and energy-adjusted and multivariate-adjusted logistic regression models.

Results

During follow-up, 1735 incident cases of hypertension occurred. The highest quartile of total polyphenol intake was associated with 31% decreased risk of hypertension compared with the lowest intake (OR 0.69, 95% CI 0.48, 0.98) in women. There was no significant association in men. Among main classes of polyphenols, flavonoids and phenolic acids were independent contributors to this association. The analysis of individual subclasses of polyphenol revealed that, among phenolic acids, hydroxycynnamic acids were independently associated to lower odds of hypertension (OR 0.66, 95% CI 0.47, 0.93), while among flavonoids, most of the association was driven by flavanols (OR 0.56, 95% CI 0.36, 0.87).

Conclusion

Certain classes of dietary polyphenols were associated with lower risk of hypertension, but potential differences between men and women should be further investigated.

Prevalence of general and abdominal obesity and overweight among adults in Poland. Results of the WOBASZ II study (2013-2014) and comparison with the WOBASZ study (2003-2005)

INTRODUCTION There are limited data on the current prevalence of overweight and obesity as well as its changes with time in Poland. OBJECTIVES The aim of the study was to assess the prevalence of general and abdominal obesity and overweight in Polish adults in the years 2013-2014, and to compare it with the prevalence in the years 2003-2005. PATIENTS AND METHODS The study was conducted in 2 independent, representative samples of the Polish population, comprising 14 537 persons (aged 20-74 years) examined in the years 2003-2005 and 6164 persons (aged ≥20 years) examined in the years 2013-2014. Anthropometric measurements were done by trained nurses. RESULTS In the years 2013-2014, the age-standardized prevalence of obesity (body mass index [BMI] ≥30 kg/m2) was 24.4% in men and 25.0% in women. The prevalence of overweight (BMI, 25.0-29.9 kg/m2) was 43.2% in men and 30.5% in women. Abdominal obesity (waist circumference ≥102 cm in men or ≥88 cm in women) was noted in 32.2% of men and 45.7% of women. Abdominal overweight (waist circumference, 94-101.9 cm in men or 80-87.9 cm in women) was present in 27.2% of men and 21.7% of women. Since the years 2003-2005, the distribution of body mass according to the BMI category had shifted to higher values, and an increase in the prevalence of obesity was observed in men. The percentage of adults with normal waist circumference decreased significantly in both sexes. CONCLUSIONS Every fourth inhabitant of Poland is obese, and during the last decade, the prevalence of obesity has increased, particularly in men. Abdominal obesity is observed in every third man and nearly every second woman, and an excess of abdominal fat has increased in both sexes.

Inequalities in mortality of infants under one year of age according to foetal causes and maternal age in rural and urban areas in Poland, 2004-2013

INTRODUCTION

European countries are characterized by low mortality during the infancy period compared to other areas of the world. However, there are significant disparities in the state of infant health which are related to socio-economic conditions and place of residence.

OBJECTIVE

Analysis of mortality in Poland from foetal and maternal causes (length of gestation, birth weight, maternal age) in the neonatal and post-neonatal period depending on place of residence (rural and urban areas) in 2004-2013.

MATERIALS AND METHOD

Data on mortality during the neonatal and infancy period in 2004-2013 was obtained from the Central Statistical Office. Diagnosed cases of deaths in rural and urban areas were analyzed, taking into account the causes of death according to ICD-10, the duration of pregnancy in weeks, birth weight, and maternal age. Trend analysis and comparison of mortality between rural and urban areas were performed using the Poisson regression model.

RESULTS

In rural areas, neonatal and post-neonatal death rates due to congenital malformations were siginificantly higher than in urban areas. The mortality rate was also higher in rural areas in children born to women aged 20-34 years, and children born after 37 weeks gestation with low birth weight. In the cities, higher post-neonatal mortality was due to respiratory diseases, and in children born after 37 weeks gestation to mothers under the age of 20 years. A decrease in the mortality of newborns and infants was observed, but in rural areas neonatal mortality decreased significantly more slowly.

CONCLUSIONS

The results indicate the need to intensify programmes aimed at improving access to prenatal and maternity care, especially among women in rural areas.

Dietary polyphenols are inversely associated with metabolic syndrome in Polish adults of the HAPIEE study

Purpose

The aim of this study was to evaluate the association between total and individual classes and subclasses of dietary polyphenol intake and prevalence of metabolic syndrome (MetS) in the Polish arm of the Health, Alcohol and Psychosocial factors In Eastern Europe cohort study.

Methods

A cross-sectional population-based survey including 8821 adults (51.4 % female) was conducted in Kraków, Poland. Dietary polyphenol intake was evaluated using food frequency questionnaires and matching food consumption data with the Phenol-Explorer database. MetS was defined according to the International Diabetes Federation definition. Linear and logistic regression models were performed to estimate odds ratios (ORs) and confidence intervals (CIs).

Results

Significant differences in age and energy intake among different categories of total dietary polyphenol intake were found. Body mass index (BMI), waist circumference (WC), blood pressure, and triglycerides were significantly lower among individuals in the higher quartiles of polyphenol intake, but a linear association was found only for BMI and WC. After adjusting for potential confounding factors, individuals in the highest quartile of polyphenol intake were less likely to have MetS (OR 0.80; 95 % CI 0.64, 0.98 and OR 0.70; 95 % CI 0.56, 0.86 for both men and women, respectively). High total polyphenol intake was negatively associated with WC, blood pressure, high lipoprotein cholesterol, and triglycerides in women, and fasting plasma glucose in both genders. Among individual classes of polyphenols, phenolic acids and stilbenes were significantly associated with MetS; lignans and stilbenes with WC; phenolic acids with blood pressure and triglycerides; and flavonoids with fasting plasma glucose. Among specific subclasses of polyphenols, hydroxycinnamic acids, flavanols, and dihydrochalcones had the most relevant role.

Conclusions

Total and individual classes and subclasses of dietary polyphenols were inversely associated with MetS and some of its components.

Coffee consumption and risk of hypertension in the Polish arm of the HAPIEE cohort study

Background/objectives

Coffee consumption has been hypothesized to be associated with blood pressure, but previous findings are not homogenous. The aim of this study was to evaluate the association between coffee consumption and the risk of developing hypertension.

Subjects/Methods

Data on coffee consumption, blood pressure, and use of anti-hypertensive medicament were derived from 2,725 participants of the Polish arm of the HAPIEE project (Health, Alcohol and Psychosocial factors In Eastern Europe) who were free of hypertension at baseline and followed up for an average of 5 years. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by multivariate logistic regression analyses and stratified for potential confounding factors.

Results

Coffee consumption was related with decreased age, smoking status, and total energy intake. Compared to persons who drink <1 cup coffee per day, systolic blood pressure was significantly associated with coffee consumption and the risk of hypertension was lower for individuals consuming 3-4 cups/day. Despite the analysis stratified by gender showed that the protective effect of coffee consumption on hypertension was significant only in women, the analysis after stratification by smoking status revealed a decreased risk of hypertension in non-smokers drinking 3-4 cups of coffee per day, in both sexes (OR 0.41, 95% CI: 0.21, 0.79 for men and OR 0.54, 95% CI: 0.29, 0.99 for women). Upper category coffee consumption (>4 cups per day) was not related with significant increased risk of hypertension.

Conclusions

Relation between coffee consumption and incidence of hypertension was related to smoking status. Consumption of 3-4 cups of coffee per day decreased risk of hypertension in non-smoking men and women only.

Environmental and socio-economic determinants of infant mortality in Poland: an ecological study

BACKGROUND

Health status of infants is related to the general state of health of women of child-bearing age; however, women's occupational environment and socio-economic conditions also seem to play an important role. The aim of the present ecological study was to assess the relationship between occupational environment, industrial pollution, socio-economic status and infant mortality in Poland.

METHODS

Data on infant mortality and environmental and socio-economic characteristics for the 66 sub-regions of Poland for the years 2005-2011 were used in the analysis. Factor analysis was used to extract the most important factors explaining total variance among the 23 studied exposures. Generalized Estimating Equations model was used to evaluate the link between infant mortality and the studied extracted factors.

RESULTS

Marked variation for infant mortality and the characteristics of industrialization was observed among the 66 sub-regions of Poland. Four extracted factors: "poor working environment", "urbanization and employment in the service sector", "industrial pollution", "economic wealth" accounted for 77.3% of cumulative variance between the studied exposures. In the multivariate regression analysis, an increase in factor "poor working environment" of 1 SD was related to an increase in infant mortality of 40 (95% CI: 28-53) per 100,000 live births. Additionally, an increase in factor "industrial pollution" of 1 SD was associated with an increase in infant mortality of 16 (95% CI: 2-30) per 100,000 live births. The factors "urbanization and employment in the service sector" and "economic wealth" were not significantly related to infant mortality.

CONCLUSION

The study findings suggested that, at the population level, infant mortality was associated with an industrial environment. Strategies to improve working conditions and reduce industrial pollution might contribute to a reduction in infant mortality in Poland.

A Mediterranean-type diet is associated with better metabolic profile in urban Polish adults: Results from the HAPIEE study

OBJECTIVE

The aim of this study was to evaluate the relationship between adherence to a Mediterranean-type diet and metabolic syndrome (MetS) in the Polish arm of the Health, Alcohol and Psychosocial factors In Eastern Europe (HAPIEE) cohort study.

MATERIALS/METHODS

A cross-sectional survey including 8821 adults was conducted in Krakow, Poland. Food intake was evaluated through a validated food frequency questionnaire and adherence to the dietary pattern was assessed using a score specifically developed for non-Mediterranean countries (MedTypeDiet score). Linear and logistic regression models were performed to estimate beta and odds ratios (ORs) and 95% confidence intervals (CIs), respectively.

RESULTS

Significant associations between the MedTypeDiet score and waist circumference (β=-0.307±0.239cm), systolic blood pressure (β=-0.440±0.428mmHg), and triglycerides (β=-0.021±0.016mmol/L) were observed. After multivariable adjustment, individuals in the highest quartile of the score were less likely to have MetS, central obesity, high triglycerides, and hypertension. Increase of one standard deviation of the score was associated with 7% less odds of having MetS (OR 0.93, 95% CI: 0.88, 0.97). When analyzing the relation of single components of the MedTypeDiet score, wine, dairy products, and the total unsaturated:saturated fatty acids ratio were associated with MetS.

CONCLUSIONS

Adherence to a Mediterranean-like diet may decrease the risk of MetS also among non-Mediterranean populations.

Fruit and vegetable consumption and mortality in Eastern Europe: Longitudinal results from the Health, Alcohol and Psychosocial Factors in Eastern Europe study

BACKGROUND

It is estimated that disease burden due to low fruit and vegetable consumption is higher in Central and Eastern Europe (CEE) and the former Soviet Union (FSU) than any other parts of the world. However, no large scale studies have investigated the association between fruit and vegetable (F&V) intake and mortality in these regions yet.

DESIGN

The Health, Alcohol and Psychosocial Factors in Eastern Europe (HAPIEE) study is a prospective cohort study with participants recruited from the Czech Republic, Poland and Russia.

METHODS

Dietary data was collected using food frequency questionnaire. Mortality data was ascertained through linkage with death registers. Multivariable adjusted hazard ratios were calculated by Cox regression models.

RESULTS

Among 19,333 disease-free participants at baseline, 1314 died over the mean follow-up of 7.1 years. After multivariable adjustment, we found statistically significant inverse association between cohort-specific quartiles of F&V intake and stroke mortality: the highest vs lowest quartile hazard ratio (HR) was 0.52 (95% confidence interval (CI): 0.28-0.98). For total mortality, significant interaction (p = 0.008) between F&V intake and smoking was found. The associations were statistically significant in smokers, with HR 0.70 (0.53-0.91, p for trend: 0.011) for total mortality, and 0.62 (0.40-0.97, p for trend: 0.037) for cardiovascular disease (CVD) mortality. The association was appeared to be mediated by blood pressure, and F&V intake explained a considerable proportion of the mortality differences between the Czech and Russian cohorts.

CONCLUSIONS

Our results suggest that increasing F&V intake may reduce CVD mortality in CEE and FSU, particularly among smokers and hypertensive individuals.

Antioxidant vitamin intake and mortality in three Central and Eastern European urban populations: the HAPIEE study

PURPOSE

The aim of the study was to assess the relationships between individual-level dietary intakes of antioxidant vitamins C, E and beta-carotene with all-cause and cause-specific mortality in three Central and Eastern European (CEE) populations.

METHODS

Data from the Health, Alcohol and Psychosocial factors in Eastern Europe cohort study were used. At the baseline survey, between 2002 and 2005, 28,945 men and women aged 45-69 years were examined in Novosibirsk (Russia), Krakow (Poland) and seven Czech towns. Deaths in the cohorts were identified through mortality registers. Cox regression was used to estimate the association between vitamin consumption and all-cause, cardiovascular (CVD) disease and cancer mortality.

RESULTS

In multivariable-adjusted analyses, there were no clear inverse associations between antioxidant vitamin intakes and mortality, although in some groups, several hazard ratios (HRs) were significant. For example, in men, compared with the lowest quintile of vitamin C intake, all-cause mortality in the third and fourth quintiles was lower by 28 % (HR 0.72; 95 % CI 0.61-0.85) and by 20 % (HR 0.80; 95 % CI 0.68-0.95), respectively. CVD mortality was lower by 35 % (HR 0.65; 95 % CI 0.50-0.84) and by 23 % (HR 0.77; 95 % CI 0.59-0.99) in third and fourth quintile of vitamin C intake, respectively. In women, the third and fourth quintiles of dietary intake of vitamin E were associated with reduced risk of all-cause death by 33 % (HR 0.67; 95 % CI 0.53-0.84) and by 23 % (HR 0.77; 95 % CI 0.61-0.97), respectively. Consumption of vitamin C, vitamin E and beta-carotene was not related to CVD mortality in women and to cancer mortality in either gender.

CONCLUSION

This large prospective cohort study in CEE populations with low prevalence of vitamin supplementation did not find a strong, dose-response evidence for protective effects of antioxidant vitamin intake.

HMG-coenzyme A reductase inhibition, type 2 diabetes, and bodyweight: evidence from genetic analysis and randomised trials

BACKGROUND

Statins increase the risk of new-onset type 2 diabetes mellitus. We aimed to assess whether this increase in risk is a consequence of inhibition of 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR), the intended drug target.

METHODS

We used single nucleotide polymorphisms in the HMGCR gene, rs17238484 (for the main analysis) and rs12916 (for a subsidiary analysis) as proxies for HMGCR inhibition by statins. We examined associations of these variants with plasma lipid, glucose, and insulin concentrations; bodyweight; waist circumference; and prevalent and incident type 2 diabetes. Study-specific effect estimates per copy of each LDL-lowering allele were pooled by meta-analysis. These findings were compared with a meta-analysis of new-onset type 2 diabetes and bodyweight change data from randomised trials of statin drugs. The effects of statins in each randomised trial were assessed using meta-analysis.

FINDINGS

Data were available for up to 223 463 individuals from 43 genetic studies. Each additional rs17238484-G allele was associated with a mean 0·06 mmol/L (95% CI 0·05-0·07) lower LDL cholesterol and higher body weight (0·30 kg, 0·18-0·43), waist circumference (0·32 cm, 0·16-0·47), plasma insulin concentration (1·62%, 0·53-2·72), and plasma glucose concentration (0·23%, 0·02-0·44). The rs12916 SNP had similar effects on LDL cholesterol, bodyweight, and waist circumference. The rs17238484-G allele seemed to be associated with higher risk of type 2 diabetes (odds ratio [OR] per allele 1·02, 95% CI 1·00-1·05); the rs12916-T allele association was consistent (1·06, 1·03-1·09). In 129 170 individuals in randomised trials, statins lowered LDL cholesterol by 0·92 mmol/L (95% CI 0·18-1·67) at 1-year of follow-up, increased bodyweight by 0·24 kg (95% CI 0·10-0·38 in all trials; 0·33 kg, 95% CI 0·24-0·42 in placebo or standard care controlled trials and -0·15 kg, 95% CI -0·39 to 0·08 in intensive-dose vs moderate-dose trials) at a mean of 4·2 years (range 1·9-6·7) of follow-up, and increased the odds of new-onset type 2 diabetes (OR 1·12, 95% CI 1·06-1·18 in all trials; 1·11, 95% CI 1·03-1·20 in placebo or standard care controlled trials and 1·12, 95% CI 1·04-1·22 in intensive-dose vs moderate dose trials).

INTERPRETATION

The increased risk of type 2 diabetes noted with statins is at least partially explained by HMGCR inhibition.

Perceived control as a predictor of cardiovascular disease mortality in Poland. The HAPIEE study

BACKGROUND

Neither the development in methods of treatment of coronary heart disease nor the changes in exposure to main cardiovascular disease (CVD) risk factors do not fully explain the trends in CVD mortality in Poland. An influence of psychosocial factors is considered. The aims of the study were: (1) to assess the relationship between perceived control and the prevalence of classic CVD risk factors; (2) to assess the relationship between perceived control and the risk of death from all causes and from CVD.

METHODS

A cohort study with 5-year follow-up was conducted. Random sample of 10,728 permanent residents of Krakow aged 45-69 was examined. Perceived control was measured using a standard 11-item scale. The studied group was divided into four subgroups of people with very high, high, moderate, and low perceived control according to quartile values. Data on deaths and causes were obtained from the local register, death certificates and participants' families. An independent effect of perceived control on CVD mortality was assessed using Cox proportional hazards models.

RESULTS

Low perceived control was strongly associated with a higher CVD mortality, independently of age, education, marital status, history of CVD, hypertension, hypercholesterolemia, smoking, body mass index, physical activity or diabetes in both men and women (HR 2.68, 95% CI 1.36-5.31 and HR 5.18, 95% CI 1.17-22.96, respectively). After adjustment for age, both in men and women, the highest risk of death from all causes was observed in persons with low perceived control. Further adjustment for covariates attenuated the relationship.

CONCLUSIONS

Perceived control is a strong independent predictor of CVD mortality and may be considered a CVD risk factor in the Polish urban population.

Association of daily coffee and tea consumption and metabolic syndrome: results from the Polish arm of the HAPIEE study

Purpose

The aim of this study was to evaluate whether daily consumption of coffee and tea was associated with components and prevalence of metabolic syndrome (MetS) in the Polish arm of the Health, Alcohol and Psychosocial factors In Eastern Europe cohort study.

Methods

A cross-sectional population-based survey including 8,821 adults (51.4 % female) was conducted in Krakow, Poland. Coffee and tea consumption was evaluated using food frequency questionnaires. MetS was defined according to the International Diabetes Federation definition. Linear and logistic regression models were performed to estimate odds ratios and confidence intervals.

Results

Among high coffee and tea consumers (3 or more cups/day), high prevalence of female gender, young age, medium–high educational and occupational level, high total energy intake, and smoking habit were found. High coffee drinkers had lower BMI, waist circumference, systolic and diastolic blood pressure, triglycerides, and higher HDL cholesterol than those drinking less than 1 cup/day. In contrast, high tea consumers had lower BMI, waist circumference, but not diastolic blood pressure, which was higher than low drinkers. After adjusting for potential confounding factors, both higher coffee and tea consumption were negatively associated with MetS (OR 0.75, 95 % CI 0.66, 0.86 and OR 0.79, 95 % CI 0.67, 0.92, respectively). Among specific components of MetS, high coffee consumption was negatively associated with waist circumference, hypertension, and triglycerides, whereas tea consumption with central obesity and fasting plasma glucose in women, but not in men.

Conclusions

Coffee and tea consumption was negatively associated with MetS and some of its components.

Estimated dietary intake and major food sources of polyphenols in the Polish arm of the HAPIEE study

Objective

The aim of this study was to estimate the intake of known individual polyphenols and their major dietary sources in the Polish arm of the HAPIEE (Health, Alcohol and Psychosocial factors In Eastern Europe) study.

Methods

A total of 10,477 random sample (45–69 y) of urban population of Krakow, Poland, completed a validated 148-item food frequency questionnaire. Polyphenol intake was calculated by matching food consumption data with the recently developed Phenol-Explorer database.

Results

The mean intake of polyphenols was 1756.5 ± 695.8 mg/d (median = 1662.5 mg/d). The main polyphenol groups were flavonoids (897 mg/d) and phenolic acids (800 mg/d). A total of 347 polyphenols from 19 polyphenol subclasses were found. The individual compounds with the highest intakes were isomers of chlorogenic acid (i.e., 5-caffeoylquinic acid and 4-caffeoylquinic acid) among hydroxycinnamic acids (average intake 150 mg/d), that largely originated from coffee, and compounds belonging to the catechin chemical family (i.e., [+]-gallocatechin, [-]-epigallocatechin 3-O-gallate, and [-]-epicatechin) among flavanols (average intake 50 mg/d), that mostly originated from tea and cocoa products.

Conclusions

The current study provides the most updated data for individual polyphenols intake in the diet of a well-established nutritional cohort. These findings will be useful to assess potential beneficial role on health of specific foods with high polyphenol content and characterize the effects of individual phenolic compounds.

Cost-effectiveness of a cardiovascular disease primary prevention programme in a primary health care setting. Results of the Polish part of the EUROACTION project

BACKGROUND

Well designed cardiovascular disease (CVD) prevention programmes appear to be generally applicable and effective in reducing exposure to risk factors and the incidence of disease. However, introducing them broadly into clinical practice would have a significant impact on the healthcare budget, and requires careful consideration.

AIM

The purpose of this health economic analysis was to assess the potential cost-effectiveness of the model nurse-led, comprehensive CVD primary prevention programme which was prepared and introduced in the EUROACTION project, in high-risk patients in Poland.

METHODS

A Markov model was developed to assess the long-term costs of preventive intervention. The health states modelled were: event-free (all patients at the beginning of observation), stable angina first year, acute myocardial infarction, stable angina subsequent year, myocardial infarction subsequent year, CVD death, and other causes of death. Health benefits from the reduction in risk factors were estimated based on Framingham risk function assuming the probability of defined health states according to British registers. The time horizon of the analysis was ten years, and one Markov cycle length was one year. The analysis was prepared from the healthcare payer's perspective. A willingness to pay threshold of three gross domestic product (GDP) per capita / quality-adjusted life years (QALY) was used. Univariate sensitivity analysis was conducted. Results were presented as an incremental cost-effectiveness ratio (ICER) expressed as an incremental cost per QALY.

RESULTS

In Poland, EUROACTION intervention resulted mainly in reductions in the prevalence of smoking (by 14%) and high blood pressure (by 7%). Intervention on other risk factors, including blood lipids, was found to be less effective. Estimated ICERs were 19,524 PLN for men and 82,262 PLN for women. The programme was even more cost-effective in smokers i.e. estimated ICERs were 12,377 PLN in men and 53,471 PLN in women. The results were most sensitive to variations in health states utilities and cost value range as well as the duration of treatment effect.

CONCLUSIONS

The model nurse-led, comprehensive CVD primary prevention programme developed in the EUROACTION project appears to be potentially highly cost-effective for high-risk male patients in Poland (below 1 GDP per capita per QALY). For women, the cost-effectiveness was less but still below the acceptable threshold (below three GDP per capita per QALY), although the sensitivity analysis showed that results were a subject of some uncertainty.

Age at natural menopause in three central and eastern European urban populations: the HAPIEE study

OBJECTIVES

To investigate the age at menopause in three urban populations in Central and Eastern Europe and to assess whether the (suspected) differences can be explained by a range of socioeconomic, reproductive and behavioural factors.

METHODS

The Health, Alcohol and Psychosocial factors in Eastern Europe (HAPIEE) Study examined random samples of populations aged 45-69 years in Novosibirsk (Russia), Krakow (Poland) and six Czech towns. Participants completed a questionnaire and attended an examination in clinic. A total of 12,676 of women were included in these analyses.

RESULTS

The median age at menopause was 50 years in Novosibirsk, 51 years in Czech towns and 52 years in Krakow; the Cox regression hazard ratios of menopause, compared with Krakow, were 1.47 (95% CI 1.40-1.55) for Novosibirsk and 1.10 (1.04-1.16) for Czech women. In multivariate analyses, higher education, using vitamin and mineral supplements and ever use of oral contraceptives were associated with later menopause, while smoking, abstaining from alcohol and low physical activity were associated with earlier menopause. These factors, however, did not explain the differences between populations; the multivariate hazard ratios of menopause, compared with Krakow, were 1.48 (1.40-1.57) for Novosibirsk and 1.11 (1.05-1.17) for Czech women.

CONCLUSIONS

In this large population based study, differences in age at menopause between Central and Eastern Europe populations were substantial and unexplained by a range of risk factors. Associations of age at menopause with risk factors were largely consistent with studies in other populations.

Dietary habits in three Central and Eastern European countries: the HAPIEE study

BACKGROUND

The high cardiovascular mortality in Eastern Europe has often been attributed to poor diet, but individual-level data on nutrition in the region are generally not available. This paper describes the methods of dietary assessment and presents preliminary findings on food and nutrient intakes in large general population samples in Russia, Poland and the Czech Republic.

METHODS

The HAPIEE (Health, Alcohol and Psychosocial factors In Eastern Europe) study examined random samples of men and women aged 45-69 years at baseline in Novosibirsk (Russia), Krakow (Poland) and six Czech urban centres in 2002-2005. Diet was assessed using a food frequency questionnaire (at least 136 items); complete dietary information was available for 26,870 persons.

RESULTS

Total energy intakes among men ranged between 8.7 MJ in the Czech sample and 11.7 MJ in the Russian sample, while among women, energy intakes ranged between 8.2 MJ in the Czech sample and 9.8 MJ in the Russian sample. A Healthy Diet Indicator (HDI), ranging from a score of 0 (lowest) to 7 (highest), was developed using the World Health Organisation's (WHO) guidelines for the prevention of chronic diseases. The mean HDI scores were low, ranging from 1.0 (SD = 0.7) among the Polish subjects to 1.7 (SD = 0.8) among the Czech females. Very few subjects met the WHO recommended intakes for complex carbohydrates, pulses or nuts; intakes of saturated fatty acids, sugar and protein were too high. Only 16% of Polish subjects met the WHO recommendation for polyunsaturated fat intake. Consumption of fruits and vegetables was lower than recommended, especially among those Russian subjects who were assessed during the low intake season. Fewer than 65% of subjects consumed adequate amounts of calcium, magnesium and potassium, when compared with the United Kingdom's Reference Nutrient Intake.

CONCLUSION

This first large scale study of individual-based dietary intakes in the general population in Eastern Europe implies that intakes of saturated fat, sugar and complex carbohydrates are a cause for concern. The development of country-specific nutritional tools must be encouraged and nutritional campaigns must undergo continuing development.

The relationship between resting heart rate and atherosclerosis risk factors

BACKGROUND AND AIM

The imbalance between sympathetic and parasympathetic activity is one of the important factors in pathogenesis of cardiovascular diseases (CVD). There is a relationship between sympathetic activity and some CVD risk factors. Also heart rate (HR) is related to the autonomic nervous system. We analysed the relation of mean resting HR to hypertension, diabetes, obesity and to some risk factors [body mass index (BMI), hsCRP, systolic blood pressure (SBP), diastolic blood pressure (DBP), LDL cholesterol (LDL), triglycerides (TG) and glucose (G)].

METHODS

6977 men and 7792 women, aged 20-74, randomly selected from the Polish population, were screened in 2003-2005 within the framework of the National Multicentre Health Survey (WOBASZ). Resting HR and blood pressure were measured 3 times using an automatic device and for analyses only the mean value of the 2nd and 3rd measurement was used.

RESULTS

Out of screened subjects, HR <60/min was found in 11% of men and 7% of women, and HR >90/min - in 6% and 5% respectively. Medication that influenced HR was taken by 16% of men and 17% of women. Resting HR was correlated (p <0.0001) with BMI, SBP, DBP, hsCRP, LDL and G in men and with SBP, DBP, hsCRP and G in women. After adjustment for medication significantly higher HR was observed both in men and in women with obesity, diabetes, hypertension, high hsCRP and in smoking persons. The prevalence of obesity, diabetes, hypertension, high hsCRP and smoking habit rose with increasing HR and the highest one was found in persons with HR >90/min. In multivariate logistic regression models resting HR was positively associated with hypertension, obesity and diabetes. In men, with every increase in HR by 10 beats/min, OR for hypertension was 1.28 (95% CI: 1.22-1.35), for obesity 1.24 (95% CI 1.17-1.30) and for diabetes 1.36 (95% CI: 1.26-1.48) after adjustment for age, medication and other factors (in women: 1.42 for hypertension, 1.14 for obesity and 1.47 for diabetes).

CONCLUSIONS

Resting heart rate is correlated with cardiovascular risk factors (body mass index, blood pressure, glucose and cholesterol level) and with high hsCRP. Heart rate is positively associated with hypertension, obesity and diabetes which indirectly confirms the autonomic nervous system contribution to the pathogenesis of these diseases.
