Trends in major risk factors and mortality from main non-communicable diseases in Lithuania, 1985-2013

Five-Year Trends in Low-Density Lipoprotein Cholesterol Management in a Primary Healthcare Centre in Kaunas

Background and Objectives: Low-density lipoprotein cholesterol (LDL-C) is a marker of cardiovascular risk and its management. This study evaluated LDL-C control trends in patients treated at a primary healthcare center in Lithuania. Materials and Methods: Five-year (2019-2023) data on patients aged 40 years or older diagnosed with dyslipidemia were extracted from a real-world data and analytics platform, TriNetX. Patients were grouped into three groups: patients with dyslipidemia only (control group), patients with dyslipidemia and diabetes, and patients with dyslipidemia and cardiovascular disease (CVD). The following LDL-C goals were used for analysis: <1.4 mmol/L (a goal for very-high-risk patients in primary or secondary prevention), <1.8 mmol/L (a goal for high-risk patients), and <3.0 mmol/L (a goal for low-risk patients). Results: There were 18,646 patients with dyslipidemia. Of them, 8.9% of patients had diabetes, and 3.1% of patients had CVD. The median LDL-C concentration was significantly lower in patients with diabetes (2.82 mmol/L, p < 0.05) and in patients with CVD (2.45 mmol/L, p < 0.05) than in the control group (3.35 mmol/L). A trend of decreasing median LDL-C over the years was observed in all groups, with the lowest median values in 2023. The proportion of patients with LDL-C levels < 3 mmol/L increased from 32.0% in 2019 to 41.5% in 2023. The proportion of diabetic patients achieving LDL-C < 1.8 mmol/L increased from 7.4% to 25.9%, and those achieving LDL-C < 1.4 mmol/L increased from 3.1% to 10.6%. The proportion of patients with CVD achieving LDL-C < 1.8 mmol/L increased from 14.2% to 36.6%, and those achieving LDL-C < 1.4 mmol/L increased from 3.0% to 14.0%. Conclusions: Trends in the control of LDL-C levels are positive over 5 years, but a significant proportion of patients still did not reach the recommended target levels.

Sex differences in cognitive decline among middle-aged and older adults: a cohort study in Europe

OBJECTIVES

Previous studies on sex differences in cognitive decline provide inconsistent findings, with many European countries being underrepresented. We determined the association between sex and cognitive decline in a sample of Europeans and explored differences across birth cohorts and regions.

METHODS

Participants 50+ years old enrolled in the Survey of Health, Ageing and Retirement in Europe had their cognition measured by tests of immediate recall, delayed recall and verbal fluency biennially up to 17 years of follow-up (median 6, interquartile range 3-9 years). We used linear mixed-effects models to assess the relationship between sex and the rate of cognitive decline, adjusting for sociodemographic and health-related characteristics.

RESULTS

Of 66,670 participants (mean baseline age 63.5 ± standard deviation 9.4), 55% were female. Males and females had similar rates of decline in the whole sample in immediate recall (beta for interaction sex × time B = 0.002, 95% CI -0.001 to 0.006), delayed recall (B = 0.000, 95% CI -0.004 to 0.004), and verbal fluency (B = 0.008, 95% CI -0.005 to 0.020). Females born before World War II had a faster rate of decline in immediate recall and delayed recall compared to males, while females born during or after World War II had a slower rate of decline in immediate recall. Females in Central and Eastern Europe had a slower rate of cognitive decline in delayed recall compared to males.

DISCUSSION

Our study does not provide strong evidence of sex differences in cognitive decline among older Europeans. However, we identified heterogeneity across birth cohorts and regions.

Predictive importance of the visceral adiposity index and atherogenic index of plasma of all-cause and cardiovascular disease mortality in middle-aged and elderly Lithuanian population

Background

Two indices: visceral adiposity index (VAI) and atherogenic index of plasma (AIP) during several recent years were implemented into epidemiological studies for predicting of cardiovascular diseases (CVD) and mortality risk. Our study aimed to evaluate the association of VAI and AIP with the risk of all-cause and CVD mortality among the Lithuanian urban population aged 45–72 years.

Methods

In the baseline survey (2006–2008), 7,115 men and women 45–72 years of age were examined within the framework of the international study Health, Alcohol and Psychosocial Factors in Eastern Europe (HAPIEE). Six thousand six hundred and seventy-one participants (3,663 women and 3,008 men) were available for statistical analysis (after excluding 429 respondents with the missed information on study variables) and for them, VAI and AIP were calculated. The questionnaire evaluated lifestyle behaviors, including smoking and physical activity. All participants in the baseline survey were followed up for all-cause and CVD mortality events until December 31st, 2020. Multivariable Cox regression models were applied for statistical data analysis.

Results

After accounting for several potential confounders, higher levels of VAI (compared 5th quintile to 1st quintile) were associated with significantly higher CVD mortality in men [Hazards ratio (HR) = 1.38] and all-cause mortality in women (HR = 1.54) after 10-year follow-up. CVD mortality significantly increased in men with 0 the highest AIP quintile compared with that for the lowest quintile (HR = 1.40). In women, all-cause mortality was significantly higher for the 4th quintile of AIP as compared with the 1st quintile (HR = 1.36).

Conclusions

High-risk VAI levels were statistically significantly associated with all-cause mortality risk in men and women groups. The higher AIP level (5th quintile vs. 1st quintile—in men and 4th quintile vs. 1st quintile—in women) was significantly associated with increased mortality from CVD in the men group and increased all-cause mortality in the women group.

Trend Analysis of the Mortality Rates of the Top Three Causes of Death Among Chinese Residents from 2003 to 2019

Objective: To delineate the mortality trends of malignant tumors, heart disease and cerebrovascular disease in China.

Methods: The crude mortality from 2003 to 2019 was derived from the China Health Statistical Yearbook, and the mortality rates were analyzed through joinpoint regression supplemented by descriptive statistics and χ2 tests.

Results: The fitting model of age-standardized mortality due to malignant tumors showed three joinpoints. The APCs from 2003 to 2005, 2005–2008, 2008–2012 and 2012–2019 were −11.00%, 9.63%, −4.67% and −1.40%, respectively, and the AAPC was −1.54%. The mortality rate of cerebrovascular disease consistently decreased (APC = AAPC = −0.98%). In the subgroup analyses, significant differences were observed between sexes and regions. The mortality rate of heart disease among rural females exhibited an upward trend (APC = AAPC = 2.33%). Older adults aged over 75 years had the highest mortality rates and the most drastic change.

Conclusion: The three diseases had variable change trends. The government should focus more on policies that promote the equalization of basic public health services. Continuous education on heart disease, which includes not only beneficial behaviors but also knowledge of first aid, should be strengthened for rural females.

May Measurement Month 2017-2019: an analysis of blood pressure screening results from Lithuania. Eur Heart J Suppl 2022;24:F22-F24. [PMID: 36225270 PMCID: PMC9547500 DOI: 10.1093/eurheartjsupp/suac043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0]

In 2017, Lithuania joined the global May Measurement Month (MMM) campaign which aims at raising awareness of raised blood pressure worldwide. Presented here are the data arising from the 2017, 2018, and 2019 campaigns. An opportunistic cross-sectional survey of individuals aged ≥18 years was carried out in Lithuania in 2017, 2018, and 2019. Two thousand nine hundred and nineteen participants were recruited in the MMM campaigns in response to the media engagement and interactions with the study team. The mean age of participants was 46.1 years (SD 16.3) years, 58.9% were females. Blood pressures were measured using electronic devices provided by Omron according to the MMM protocol. Of the 2919 screened participants, 1308 (44.8%) had hypertension. Of all hypertensive participants, the awareness rate, the treatment rate, and the control rates (<140/90 mmHg) were 79.5%, 41.0%, and 14.2%, respectively. Of those on antihypertensive medication, the control rate was 34.8%. The high percentage of participants with hypertension was either untreated (59.0%) or treated but uncontrolled (65.2%) suggests the usefulness of such screening programmes to improve awareness of hypertension control in Lithuania.

Cardiovascular diseases mortality and alcohol control policy in Lithuania: exploring a possible link

Background

Lithuania possesses one of the highest alcohol per capita consumption and has previously implemented alcohol control policies to reduce the alcohol-attributable burden. The aim of this study was to investigate Lithuanian cardiovascular disease (CVD) mortality rate trends between 2001 and 2018 and to explore a possible link between CVD mortality rate and alcohol control policy implementation.

Methods

Lithuanian population mortality and alcohol consumption data for 2001–2018 were obtained from Statistics Lithuania and The State Register of Death Cases and Their Causes, Institute of Hygiene. Sex-specific CVD mortality rates were directly standardized to the European standard population by five-year age groups and categorized according to the ICD-10 codes for all CVDs (I00-I99), ischemic heart disease (IHD) (I20-I25), cerebrovascular diseases (I60-I69) and alcoholic cardiomyopathy (ACM) (I42.6). Joinpoint regression analyses were performed to identify points of inflection to explore their alignment with five selected alcohol policy enactments.

Results

Overall, the 2001–2018 yearly mortality rates for all CVDs significantly decreased on average by − 1.6% (95% CI -2.0, − 1.2%) among men and − 2.1% (95% CI -2.5, − 1.8%) among women. Yearly changes in all CVDs, IHD, cerebrovascular diseases and ACM mortality rates were insignificant prior to their respective critical year points in 2006, 2005, 2008 and 2007, but significantly decreased afterwards by an average of − 2.4% (95% CI -2.7, − 2.0%), − 1.6% (95% CI -2.1, − 1.1%), − 1.2% (95 CI -1.7, − 0.6%) and − 4.5% (95% CI -7.3, − 1.6%) among men, and by − 2.7% (95% CI -3.0, − 2.3%), − 2.0% (95% CI -2.6, − 1.4%), − 1.8% (95% CI 2.4, − 1.3%) and − 6.6% (95% CI -10.7, − 2.2%) among women, respectively. The changes in the mortality rate trends for all CVDs, IHD, cerebrovascular diseases and especially ACM coincided with alcohol policies enacted on the January 1, 2008, January 1, 2009, April 1, 2014 and March 1, 2017.

Conclusions

Yearly mortality rates for all CVDs, IHD, cerebrovascular diseases and ACM have declined in Lithuania between 2001 and 2018, and declining trends were more prominent in women than in men. Among the ICD-10 CVD categories investigated, the points of inflection identified for the ACM mortality rate trend coincided best with the selected alcohol policy enactment dates.

Changes in Cardiovascular Risk Factors in Residents of the Siberian Region (According to Epidemiological Studies)

Aim. To analyze prevalence of cardiovascular risk factors in the Kemerovo region based on the results of epidemiological studies (2013 and 2016).

Material and methods. The study was based on two large epidemiological studies of the Kemerovo region: on 2013, «The epidemiology of cardiovascular diseases and their risk factors in the Russian Federation» and on 2016, «The prospective study of urban and rural epidemiology: study of the influence of social factors on chronic non-infectious diseases in low, middle and high income countries». In the study we analyzed cardiovascular risk factors using identical questionnaires, functional, anthropometric, biochemical means and measured on identical scales. As a result, we analyzed the prevalence of smoking, diabetes mellitus, overweight and obesity, abdominal obesity, hypercholesterolemia and hypertriglyceridemia, high levels of low-density lipoprotein (LDL).

Results. Univariate analysis indicates that in the sample of 2016, compared to the sample of 2013, the prevalence of smoking is statistically significantly lower, as well as the proportion of participants with high cholesterol levels, but not taking lipid-lowering drugs. In contrast, the prevalence of diabetes, hypercholesterolemia and hypertriglyceridemia is higher. In women, the frequency of abdominal obesity on 2016 is lower than on 2013: at 35-44 age group odds ratio (OR) =0.67 with 95% confidence interval (CI) 0.44-1.03, at 45-54 age group OR =0.47 with 95% CI 0.31-0.72, 55-65 age group OR =0.49 with 95% CI 0.30-0.79. A high incidence of diabetes, hypercholesterolemia and hypertriglyceridemia is characteristic mainly of older women (55-65 age group): accordingly, OR =1.96 with 95% CI 1.19-3.22, OR =1.42 with 95% CI 1,02-1.97, OR =1.51 at 95% CI 1.08-2.12. In the 45-54 age group of men, they smoked statistically significantly less often on 2016 compared to 2013, OR =0.59 with 95% CI 0.36-0.96. The prevalence of overweight and obesity in both samples is the same: for women, the OR for overweight in different age groups is within 0.74-0.87, for men - within 0.95-1.78; for obesity OR in women is from 0.70 to 0.79, in men - from 1.03 to 1.34.

Conclusion. A significant advantage of the study is the analysis of changes in prevalence in age and gender groups, which showed significant differences in the dynamics of men and women in different age categories for a number of risk factors. Analysis of the dynamics of the prevalence of cardiovascular risk factors makes it possible to assess the effectiveness of state and regional policies in the field of health protection and, first of all, "risk groups” that require closer attention, development and implementation of targeted health-saving technologies.

Trends and age-period-cohort analysis of upper aerodigestive tract and stomach cancer mortality in Lithuania, 1987-2016

OBJECTIVES

Lithuania has among the highest mortality rates for upper aerodigestive tract (UADT) and stomach cancer in Europe. The aim of this study was to analyze trends during the period 1987-2016 in Lithuania, evaluating the effect of birth-cohort, period, and age.

STUDY DESIGN

Observational time trends study.

METHODS

Data on numbers of deaths and population size by each calendar year in 5-year age groups in 1987-2016 were obtained from the WHO mortality database. Joinpoint regression analysis was used to evaluate changes in time trends. Age-period-cohort analysis was performed to assess age, calendar period of death, and birth-cohort effects.

RESULTS

UADT cancer mortality in men increased between 1987 and 1993, annual percentage change (APC) = 6.6% (95% confidence interval [CI]: 3.8, 9.4), and was stable thereafter, APC = 0.3% (95% CI: 0.0, 0.6). The age-standardized mortality rate (ASMR) was 23.6/100,000 in 2016. In women, rates increased steadily by 1.6% (95% CI: 0.9%, 2.3%) per year from 1987 to 2016, ASMR = 2.3/100,000 in 2016. Age-period-cohort analysis showed statistically significant cohort effects in both sexes. In men, rates peaked in birth-cohorts born around 1952, declined in 1957-1962 birth-cohorts, and fluctuated in later birth-cohorts. In women, rates started rising in 1947 birth cohort and peaked in the 1967 birth cohort. Stomach cancer mortality declined throughout the study period in men by -2.4%, (95% CI: -2.6%, -2.1%) annually, and women by -2.8% (95% CI: -3.1%, -2.4%), ASMR = 16.1/100,000 and 6.0/100,000 in 2016, respectively. Birth-cohort effects were significant in both sexes. Rates decreased in cohorts born around 1920 onwards, but declines in the youngest generations have slowed in men and reversed in women.

CONCLUSIONS

The birth-cohort effects in UADT and stomach cancer mortality trends imply that the elevated burden in Lithuania could be reduced by effective strategies targeting known risk factors. Further research in causes of unfavorable trends in younger cohorts is warranted.

All-Cause Mortality Risk in National Prostate Cancer Cohort: An Impact of Population-Based Prostate Cancer Screening

The aim of this study is to evaluate all-cause mortality risk differences before and during prostate cancer screening, with a profound focus on the differences between screened and not-screened patient groups. Prostate cancer cases diagnosed between 1998 and 2016 were identified from the population-based Lithuanian Cancer Registry and linked with screening status in the National Health Insurance Fund database. The analysis was stratified by a period of diagnosis and screening status. Standardized mortality ratios (SMRs) were used to assess all-cause and cause-specific mortality risk. The SMRs were calculated by dividing the observed number of deaths among prostate cancer patients by the expected number of deaths from the general population. All-cause SMR (1.45 (95% CI 1.42-1.48)) in the pre-screening period was higher compared to the screening period (SMR = 1.17 (95% CI 1.15-1.19)). An increased all-cause mortality risk among prostate cancer patients was observed in the not-screened patient population (SMR = 1.76 (95% CI 1.71-1.82)), while all-cause mortality risk in the screened patient population was similar to the general population (SMR = 1.00 (95% CI 0.97-1.02)). Screened patients with localized stage of disease had lower all-cause mortality risk than the general population (SMR = 0.72 (95% CI 0.70-0.75)). In conclusion, men with prostate cancer in Lithuania had excess all-cause mortality risk compared to the general population. The all-cause mortality risk among screened patients was not higher than expected.

30-year trends in major cardiovascular risk factors in the Czech population, Czech MONICA and Czech post-MONICA, 1985 - 2016/17

Background

Compared with Western Europe, the decline in cardiovascular (CV) mortality has been delayed in former communist countries in Europe, including the Czech Republic. We have assessed longitudinal trends in major CV risk factors in the Czech Republic from 1985 to 2016/17, covering the transition from the totalitarian regime to democracy.

Methods

There were 7 independent cross-sectional surveys for major CV risk factors conducted in the Czech Republic in the same 6 country districts within the WHO MONICA Project (1985, 1988, 1992) and the Czech post-MONICA study (1997/98, 2000/01, 2007/08 and 2016/2017), including a total of 7,606 males and 8,050 females. The population samples were randomly selected (1%, aged 25–64 years).

Results

Over the period of 31/32 years, there was a significant decrease in the prevalence of smoking in males (from 45.0% to 23.9%; p < 0.001) and no change in females. BMI increased only in males. Systolic and diastolic blood pressure decreased significantly in both genders, while the prevalence of hypertension declined only in females. Awareness of hypertension, the proportion of individuals treated by antihypertensive drugs and consequently hypertension control improved in both genders. A substantial decrease in total cholesterol was seen in both sexes (males: from 6.21 ± 1.29 to 5.30 ± 1.05 mmol/L; p < 0.001; females: from 6.18 ± 1.26 to 5.31 ± 1.00 mmol/L; p < 0.001).

Conclusions

The significant improvement in most CV risk factors between 1985 and 2016/17 substantially contributed to the remarkable decrease in CV mortality in the Czech Republic.

Body mass index and other risk factors for kidney cancer in men: a cohort study in Lithuania

OBJECTIVES

Previous studies have observed notable unexplained geographic differences in incidence of kidney cancer in Europe. Lithuania is among the countries with the highest incidence and mortality. Our objective was to investigate the effect of different lifestyle, anthropometric and biological factors on the risk of kidney cancer in Lithuanian men.

METHODS

This population-based cohort study included 6,849 men initially free from cancer. During the follow-up (1978-2008), 79 incident cases of kidney cancer were identified. Cox proportional hazards regression models were used to estimate hazard ratios (HR) and corresponding 95% confidence intervals (95% CI).

RESULTS

Risk of kidney cancer was significantly associated with increasing body mass index (BMI), the adjusted HR for ≥ 35 vs. < 25 kg/m² was 3.00, 95% CI 1.10-8.19 and the HR per 1 unit increment of BMI was 1.07, 95% CI 1.01-1.14. In overweight men (BMI ≥ 25 kg/m²), the HRs for kidney cancer per 10 mmHg increment of systolic or diastolic blood pressure were 1.10, 95% CI 0.96-1.25 and 1.26, 95% CI 1.01-1.56, respectively. We found no significant association between smoking, alcohol consumption or total serum cholesterol level and kidney cancer risk.

CONCLUSIONS

This study supports a link between increased BMI and the development of kidney cancer among men in Lithuania. Hypertension appears to be associated with risk of kidney cancer in overweight men, although the assessment was limited by the lack of statistical power.

The Impact of Metabolic Syndrome and Lifestyle Habits on the Risk of the First Event of Cardiovascular Disease: Results from a Cohort Study in Lithuanian Urban Population

Background and Objectives: In recent years, the impact of individual risk factors on mortality from cardiovascular diseases (CVD) has been often investigated. However, there is a lack of studies that have evaluated the relationship between lifestyle habits, metabolic syndrome, and their combined influence on the first event of CVD. The aim of this study was to investigate the impact of metabolic syndrome and lifestyle habits on the risk of the first event of CVD in a Lithuanian urban population. Materials and Methods: The presented data were collected from a survey that was carried out within the framework of the international project Health, Alcohol and Psychosocial Factors in Eastern Europe (HAPIEE). For statistical analysis, 4257 participants aged 45–72 years were selected (with a follow-up of 11 years). Results: The findings from the Cox proportional hazards regression multivariable analysis showed that metabolic syndrome, current smoking status, and former smoking status increased the risk of the first event of CVD among men (with respective hazard ratios (HR) of 1.53, 1.94, and 1.43; p < 0.01). In women, metabolic syndrome increased the risk of the first event of CVD (HR = 1.56; p = 0.001), while the increased consumption of fresh vegetables and fruits decreased the risk of the first event of CVD (HR = 0.80; p = 0.003). Multivariable logistic regression analysis results show that a level of increased physical activity by one hour can be linked to a lower risk of metabolic syndrome by 2% among men (odds ratio (OR) = 0.98; p = 0.001). Conclusions: Metabolic syndrome and lifestyle habits including cigarette smoking in men and low consumption of fresh vegetables and fruits in women are strong predictors of the first event of CVD.

Efficacy and safety of different doses of azilsartan medoxomil in patients with hypertension: A protocol of a network meta-analysis

BACKGROUND

Hypertension is one of the most common chronic diseases and an increasingly public-health challenge worldwide. Previous meta-analyses evaluated the effects of azilsartan medoxomil compared to placebo or other antihypertensive drugs in patients with hypertension. However, it is still unclear which dose of azilsartan is optimal. This study will perform a network meta-analysis to assess the efficacy and safety of different doses of azilsartan medoxomil in patients with hypertension.

METHODS

PubMed, EMBASE.com, the Cochrane library, Scopus, and Web of Science were searched from inception to May 2019. Randomized controlled trials reporting efficacy and safety of different doses of azilsartan medoxomil on hypertension will be included if they compared 1 dose of azilsartan medoxomil with another dose of azilsartan medoxomil or with a placebo. Risk of bias of the included trials will be evaluated according to the Cochrane Handbook 5.1.0. NMA will be performed in a Bayesian hierarchical framework using WinBUGS 14.

RESULTS

The results will be submitted to a peer-reviewed journal for publication.

CONCLUSION

This study will summarize all the available data to provide reliable evidence of the value of different doses of azilsartan medoxomil for the treatment of hypertension.

Long-term survival after stroke in Lithuania: Data from Kaunas population-based stroke registry

BACKGROUND

There is a lack of reliable epidemiological data on long-term survival trends of first-ever stroke patients in Lithuanian population.

AIMS

To evaluate trends in long-term survival after stroke and to determine the influence of some sociodemographic and lifestyle factors, time and subtype of stroke, and stroke care on survival.

METHODS

All stroke events included in Kaunas stroke register database were ascertained and validated according to the standardized criteria outlined by the WHO MONICA Project. The study included all patients in Kaunas (Lithuania) city aged 25 to 64 years who experienced a stroke between 1986 and 2011. Death time was confirmed by the Office for National Death Statistics. Estimates of stroke long-term survival data and factors influencing survival changes were made by applying the Kaplan-Meier and Cox regression analysis.

RESULTS

During the study period, 4,129 persons aged 25-64 years suffered from a first-ever stroke: 2,215 (53.6%) of them were men and 1,914 (46.4%)-women. Ischemic stroke was significantly more frequent in males than in females (80.6% and 78.6%, respectively, p<0.05) and subarachnoid hemorrhage was more common in women than in men (9.0% and 7.0% respectively, p <0.05). Of all first-ever stroke patients, 3,272 (79.2%) survived 1 year and 2,905 (70.4%) survived 5 years after stroke onset. The 1- and 5-years survival rate after a first-ever stroke in women was significantly higher as compared with that in men (Log-rank test p = 0.0001). The older (55-64 year) persons had poorer 1-year and 5-years survival rate as compared with persons in the younger (25-54 years) age group (Log-rank test p = 0.0001). Among persons with a first-ever stroke who had their stroke in 2007-2011, 1- and 5-year survival rate was higher compared with that in persons who had had a stroke in 1986-1990 and in 1997-2001 (Log-rank test p = 0.0001). The persons with a first-ever ischemic stroke had a better chance to survive first 1- and 5-years after stroke compared with persons who had intracerebral or subarachnoid haemorrhage. Only female gender was associated with higher 1- and 5-year survival rate after first-ever stroke. The older age, previous myocardial infarction and diabetes mellitus were associated with lower 1- and 5-year survival rate after first-ever stroke.

CONCLUSIONS

This population-based study of patients with first-ever stroke demonstrated that the long-term survival was better in women than men, and improved significantly in both men and women during the past decade. Long-term survival was better of those with first-ever ischemic stroke and of younger age- 25 to 54 years.

Holistic physical exercise training improves physical literacy among physically inactive adults: a pilot intervention study

BACKGROUND

Physical literacy (PL), given as a multidimensional construct, is considered a person's capacity and commitment to a physically active lifestyle. We investigated the effect of a holistic physical exercise training on PL among physically inactive adults.

METHODS

A non-randomised controlled study was conducted. Thirty-one physically inactive adults in the intervention group (IG; 81% females, 44 ± 16 years) participated in a holistic physical exercise training intervention once weekly for 15 weeks. A matched, non-exercising control group (CG) consisted of 30 physically inactive adults (80% female, 45 ± 11 years). PL, compliance and sociodemographic parameters were measured. PL was evaluated by a questionnaire, covering five domains: physical activity behaviour, attitude towards a physically active lifestyle, exercise motivation, knowledge and self-confidence/self-efficacy. Data were analysed using ANCOVA models, adjusted for age, gender and BMI at baseline.

RESULTS

At post-training intervention, the IG showed significant improvements in PL (p = 0.001) and in the domains physical activity behaviour (p = 0.02) and exercise self-confidence/self-efficacy (p = 0.001), with no changes overserved for the CG regarding PL and those domains. No intervention effect were found for the other three domains, i.e. attitude, knowledge and motivation. Additionally, for the IG baseline BMI was identified to be positively correlated with physical exercise-induced improvements in PL (β = 0.51, p = 0.01).

CONCLUSIONS

The results from this study are very useful for further public health activities, which aim at helping physically inactive adults to adopt a physically active lifestyle as well as for the development of further PL intervention strategies. This pilot-study was a first attempt to measure PL in inactive adults. Yet, a validated measurement tool is still not available. Further research is necessary to determine the psychometric properties for this PL questionnaire.

Trends in electrocardiographic abnormalities and risk of cardiovascular mortality in Lithuania, 1986-2015

Background

This study aimed to assess the trends in the prevalence of electrocardiographic (ECG) abnormalities from 1986 to 2015 and impact of ECG abnormalities on risk of death from cardiovascular diseases (CVD) in the Lithuanian population aged 40–64 years.

Methods

Data from four surveys carried out in Kaunas city and five randomly selected municipalities of Lithuania were analysed. A resting ECG was recorded and CVD risk factors were measured in each survey. ECG abnormalities were evaluated using Minnesota Code (MC). Trends in age-standardized prevalence of ECG abnormalities were estimated for both sexes. Multivariate Cox proportional hazards models were used to estimate hazard ratios (HR) for coronary heart disease (CHD) and CVD mortality. Net reclassification index (NRI), integrated discrimination improvement and other indices were used for evaluation of improvement in the prediction of CVD and CHD mortality risk after addition of ECG abnormalities variable to Cox models.

Results

From1986 to 2008, the decrease in the prevalence of Q-QS MC was observed in both genders. The prevalence of high R waves increased in men, while the prevalence of ST segment and T wave abnormalities as well as arrhythmias decreased in women. Ischemic changes and possible MI were associated with a 2.5-fold and 4.4-fold higher risk of death from CVD in men and 1.51-fold and 2.56-fold higher mortality risk from CVD in women as compared to individuals with marginal or no ECG abnormalities. The addition of ECG abnormalities to traditional CVD risk factors improved Cox regression models performance. According to NRI, 18.6% of men were correctly reclassified in CVD mortality prediction model and 25.2% of men - in CHD mortality prediction model.

Conclusions

the decreasing trends in the prevalence of ischemia on ECG in women and increasing trends in the prevalence of left VH in men were observed. ECG abnormalities were associated with higher risk of CVD mortality. The addition of ECG abnormalities to the prediction models modestly improved the prediction of CVD mortality beyond traditional CVD risk factors. The use of ECG as routine screening to identify high risk individuals for more intensive preventive interventions warrants further research.

Six-year changes in the prevalence of obesity and obesity-related diseases in Northeastern China from 2007 to 2013

Obesity and obesity-related diseases are important public health challenges. In this study, we aimed to provide updated trends in the prevalence of these conditions. We conducted two independent cross-sectional surveys of the general population aged 20–75 years in 2007 and 2013 in Jilin, China. A total of 3636 (1719 males) and 1359 (602 males) participants were enrolled in the 2007 and 2013 surveys, respectively. Obesity-related diseases were defined as type 2 diabetes, hypertension, dyslipidemia and non-alcoholic fatty liver disease (NAFLD). The age-standardized prevalence of obesity, overweight, diabetes, pre-diabetes, dyslipidemia and NAFLD increased from 2007 to 2013 from 15.82% to 19.41%, 35.85% to 41.80%, 6.37% to 9.23%, 16.77% to 23.49%., 53.46% to 65.50%, and 23.48% to 44.31% in males, respectively, and from 13.18% to 18.77%, 31.11% to 37.54%, 4.41% to 8.48%, 8.10% to 16.49%, 41.96% to 54.70%, and 17.56% to 43.06% in females, respectively. However, the prevalence of hypertension remained stable (males: 38.10% vs. 38.63% and females: 33.04% vs. 33.01% in 2007 and 2013, respectively). The prevalence of obesity and obesity-related diseases, except for hypertension, increased significantly in the general population in Northeastern China. More targeted measures should be implemented to address the serious challenges presented by these diseases.

Decline in Cardiovascular Mortality: Possible Causes and Implications

If the control of infectious diseases was the public health success story of the first half of the 20th century, then the decline in mortality from coronary heart disease and stroke has been the success story of the century's past 4 decades. The early phase of this decline in coronary heart disease and stroke was unexpected and controversial when first reported in the mid-1970s, having followed 60 years of gradual increase as the US population aged. However, in 1978, the participants in a conference convened by the National Heart, Lung, and Blood Institute concluded that a significant recent downtick in coronary heart disease and stroke mortality rates had definitely occurred, at least in the US Since 1978, a sharp decline in mortality rates from coronary heart disease and stroke has become unmistakable throughout the industrialized world, with age-adjusted mortality rates having declined to about one third of their 1960s baseline by 2000. Models have shown that this remarkable decline has been fueled by rapid progress in both prevention and treatment, including precipitous declines in cigarette smoking, improvements in hypertension treatment and control, widespread use of statins to lower circulating cholesterol levels, and the development and timely use of thrombolysis and stents in acute coronary syndrome to limit or prevent infarction. However, despite the huge growth in knowledge and advances in prevention and treatment, there remain many questions about this decline. In fact, there is evidence that the rate of decline may have abated and may even be showing early signs of reversal in some population groups. The National Heart, Lung, and Blood Institute, through a request for information, is soliciting input that could inform a follow-up conference on or near the 40th anniversary of the original landmark conference to further explore these trends in cardiovascular mortality in the context of what has come before and what may lie ahead.
