Proportions of trans fatty acids in erythrocytes of Canadian adults before the prohibition of partially hydrogenated oils in foods: results from the Canadian Health Measures Survey 2012–2015

BackgroundThe partially hydrogenated oil (PHO) prohibition came into effect in Canada in September 2018 to reduce the intakes of total trans fatty acids (t-TFAs) and industrially produced TFAs (i-TFAs). ObjectivesWe aimed to estimate the red blood cell (RBC) proportions of t-TFA (primary objective) and total 18:1 TFA (secondary objective) of adults in Canada before the PHO prohibition and to identify the population subgroups at risk of higher TFA intakes. MethodsWe pooled data from 4025 adult participants of the cross-sectional Canadian Health Measures Survey cycles 3 and 4 (2012–2015). We estimated mean proportions, relative to total fatty acids (FAs), of RBC t-TFA and 18:1 TFA and their associations with sociodemographic, health, and lifestyle characteristics using multiple linear regression models. ResultsThe nonadjusted mean RBC proportions of t-TFA and total 18:1 TFA were 0.59% (95% CI: 0.54, 0.63) and 0.27% (95% CI: 0.25, 0.29), respectively. In the adjusted models, the same participant characteristics were associated with t-TFA and 18:1 TFA but differences were generally smaller for 18:1 TFA than for t-TFA. Race, BMI, and alcohol intake were independently associated with RBC t-TFA and 18:1 TFA. Asian and Black participants had lower RBC t-TFA (−0.05% and −0.10% of total FA, respectively) than White participants. Obesity and high risk alcohol drinking were associated with slightly lower (≤0.06%) t-TFA proportions than lower adiposity and alcohol intake concentrations, respectively. ConclusionsPre-PHO prohibition in food in Canada, t-TFA proportions were relatively low compared with a proposed threshold of 1% of total RBC FAs, over which cardiovascular disease risk may be higher. Previous voluntary initiatives to reduce i-TFA in the food supply may explain these relatively low RBC t-TFA concentrations. Some population subgroups had higher baseline RBC TFA than other subgroups, but the physiological implications of these small differences, at relatively low baseline RBC TFA proportions, remain to be determined.

Preventive health behaviors among people with suicide ideation using nationwide cross-sectional data in South Korea

This study aimed to investigate the association between suicide ideation and health-related behaviors and preventive health service use behaviors. We used data from the 2017 Korea National Health and Nutrition Examination Survey (KNHANES), a nationally representative survey. The final sample included 4486 participants aged 40 years or older. Preventive health behaviors were assessed for smoking, high-risk drinking, physical activities, regular meal intake, influenza vaccination, general health examination, and cancer screening. Logistic regression was used to examine the association between suicide ideation and preventive health behaviors with a series of adjustments for covariates. In general, suicide ideation was associated with unfavorable outcomes of preventive health behaviors, except for flu vaccination. For example, the crude prevalence of suicide ideation and non-suicide ideation groups were 54.3% vs. 43.7% for flu vaccination, 23.1% vs. 41.6% for physical activity, and 24.8% vs. 18.6% for high-risk alcohol drinking. After adjustment for covariates, the associations of suicide ideation with behaviors remained significant for physical activity (OR 0.52, 95% CI 0.34–0.81) and high-risk alcohol drinking (OR 2.22, 95% CI 1.34–3.69). Suicide ideation leads to the disruption of self-management of health behaviours, especially for physical activity and high-risk alcohol drinking, independently of depressive feelings.

Factors Related to Problem Drinking in Korean Elderly

Background/Objectives: The purpose of this study is to evaluate the prevalence and related risk factors ofproblem drinking in the Korean elderly population.Method/Statistical Analysis: Participants (n=817) aged 65 years or older were selected from the KoreaNational Health and Nutrition Examination Survey [KNHANES] of 2018. Sociodemographic characteristicsand AUDIT-C score were obtained from the KNHANES dataset. AUDIT-C scores were categorized into twogroups, including low risk, high-risk alcohol drinking according to WHO guidelines. Data analysis wasperformed using SPSS WIN 25.0 program.Findings: In this study, the prevalence of high-risk alcohol drinking was 31.9%, respectively. Adjustedmean AUDIT score was higher in men, younger elderly individuals, as well as those with lower educationlevels and those that smoked. Results revealed that demographic variables, including sex, age, educationlevel, and smoking, were important factors affected high-risk drinking. In particular, since family numberand smoking were the most significant risk factor, the odds ratio for high-risk drinking among participantsthat smoked was 2.49 [(95% confidence interval (CI)=1.31-4.71)].Improvements/Applications: This study suggests that men, younger age, low educational level, andsmoking are the risk factors for a high-risk alcohol drinking

Joint Effect of Alcohol Drinking and Environmental Cadmium Exposure on Hypertension in Korean Adults: Analysis of Data from the Korea National Health and Nutrition Examination Survey, 2008 to 2013.

Hypertension is a common disease found in 1.13 billion adults worldwide. Several animal studies have provided evidence of the joint effect of alcohol drinking and cadmium exposure on hypertension. However, no epidemiologic study has examined the association between these 2 risk factors and hypertension. Therefore, we examined the individual effects of alcohol drinking and cadmium and the joint effect of their coexposure on hypertension in the general population. We analyzed data from 8,403 South Korean adults who had been randomly assigned to the Korea National Health and Nutrition Examination Survey from 2008 to 2013. Multiple linear and logistic regression analyses were conducted to estimate the association of alcohol drinking and blood cadmium concentration with blood pressure and the odds ratio (OR) for hypertension. The weighted prevalence of hypertension and high-risk drinking was 25.7 and 13.6%, respectively. The weighted geometric mean of blood cadmium levels was 0.94μg/L (95% confidence interval [CI]: 0.93 to 0.96). After adjusting for demographic characteristics, anthropometric measurements, health-related behaviors, and dietary and disease variables, the OR for hypertension in the group with the high-risk alcohol drinking was 1.67 (95% CI: 1.34 to 2.06) compared with the group without high-risk alcohol drinking. When the highest and the lowest blood cadmium quartiles were compared, the OR for hypertension was 1.46 (95% CI: 1.15 to 1.86). The positive joint effect of high-risk drinking and blood cadmium levels was statistically significant for systolic blood pressure (SBP; p=0.037) and diastolic blood pressure (DBP; p<0.001). Our results show that heavy alcohol drinking had a joint effect with cadmium exposure to increase the risk of hypertension. Future efforts are needed to reduce alcohol drinking and environmental cadmium exposure to prevent hypertension in the general population.

High-risk lifestyle and all-cause mortality in older Australians with stroke: A data linkage study

Abstract Background Stroke prevention via lifestyle modification is a public health priority in developed countries. Few studies have examined the association of high-risk lifestyle factors with long-term mortality of stroke survivors. Therefore, this study aims to explore the effect of key lifestyle factors on all-cause mortality after stroke. Methods Sample is derived from the 45 and Up Study, the largest ongoing study in the Southern Hemisphere focusing on the health of people aged 45 years and older living in NSW, Australia. The lifestyle data in the 45 and Up Study between 2006 to 2015 were linked with data from the NSW Registry of Births, Deaths and Marriages, NSW Cause of Death Unit Record File, and NSW Admitted Patient Data Collection by the Centre for Health Record Linkage. We defined a high-risk lifestyle as no vigorous exercise, smokers, or &amp;gt; 10 alcoholic drinks/week. Multivariate Cox regression model is used to examine the effect of high-risk lifestyle on survival using 10-year all-cause mortality as the main outcome, adjusted for key confounders. Results We analysed information on 8410 adults with a stroke event occurring prior to the baseline 45 and Up Study, and 31% of them died in 10 years. 6219 participants were identified as having a high-risk lifestyle at baseline. Being a current smoker and without vigorous exercise were associated with 41% (95% CI: 16%, 73%) and 52% (95% CI: 30%, 78%) increase in the likelihood of death in 10 years, respectively. However, high-risk alcohol drinking was not significantly associated with survival. Of note, having cardiovascular-related comorbidities showed greater risks of mortality (HR range, 3.6-7.2). Conclusions High-risk lifestyle factors were associated with an increased risk of long-term all-cause mortality, suggesting that enhancing public health initiatives to promote 'healthy' lifestyle behaviours can be of great benefit to stroke survivors. Key messages It is essential for stroke survivors to maintain a healthy lifestyle to delay all-cause mortality. Stroke survivors with high-risk lifestyle may be associated with increased likelihood of death if they have comorbidities such as diabetes and hypertension.

Lifestyle risk score and mortality in Korean adults: a population-based cohort study

Individual lifestyle risk factors have been associated with an increased risk of mortality. However, limited evidence is available on the combined association of lifestyle risk factors with mortality in non-Western populations. The analysis included 37,472 participants (aged ≥19 years) in the Korea National Health and Nutrition Examination Surveys (2007–2014) for whom the data were linked to death certificates/medical records through December 2016. A lifestyle risk score was created using five unhealthy behaviors: current smoking, high-risk alcohol drinking, unhealthy weight, physical inactivity, and insufficient/prolonged sleep. Cox proportional hazards models were used to estimate hazard ratio (HR) and 95% confidence interval (CI). During up to 9 years of follow-up, we documented 1,057 total deaths. Compared to individuals with zero lifestyle risk factor, those with 4–5 lifestyle risk factors had 2.01 times (HR = 2.01, 95% CI = 1.43–2.82) and 2.59 times (HR = 2.59, 95% CI = 1.24–5.40) higher risk of all-cause and cardiovascular mortality, respectively. However, higher lifestyle risk score was not significantly associated with cancer mortality (p-trend >0.05). In stratified analyses, the positive associations tended to be stronger in adults aged <65 years, unemployed, and those with lower levels of education. In conclusion, combined unhealthy lifestyle behaviors were associated with substantially increased risk of total and cardiovascular mortality in Korean adults.

The Effectiveness of a Brief Intervention for Reducing Adolescent Alcohol Consumption

Introduction: Although alcohol consumption affects more than half of all adolescents, there are no known studies to assess the effectiveness of interventions to prevent or reduce consumption at a local level. The aim of this randomized clinical trial was to determine the effectiveness and clinical significance of a brief intervention program to reduce the consumption of alcohol and related problems in an educational setting in Argentina. Materials and methods: Systematically selected high school students (N = 167) were randomly assigned to one of three conditions: two control groups (screening, screening and evaluation) and one experimental group (screening, assessment and intervention). With the approval of an Ethics Committee, we implemented a protocol based on international guidelines. The effectiveness measures used were a reduction in usual quantity, in high-risk alcohol drinking or in alcohol-related problems. We performed descriptive analyses, linear and logistic regressions, estimates of relative and absolute risk reduction, and the number of patients needed to reduce an event. In the follow-up (N = 150), the quantity of consumption and high-risk consumption were higher in the control groups. Results: The intervention effectively reduced alcohol consumption and related problems in about one out of seven adolescents, with a minimal investment in training and implementation. However, we did not find significant differences in alcohol-related problems among the groups, which decreased under all conditions. Conclusion: Long-term studies could determine whether this change primarily affects the intervention group.

The prevalence of and factors associated with urinary cotinine-verified smoking in Korean adults: The 2008-2011 Korea National Health and Nutrition Examination Survey.

BackgroundSmoking rate based on self-reporting questionnaire might be underestimated. Cotinine is the principal metabolite of nicotine and is considered an accurate biomarker of exposure to cigarette smoke.ObjectivesThis study evaluated the prevalence of and factors associated with urinary cotinine-verified smoking in Korean adults.MethodsWe analyzed data from 12,110 adults in the 2008–2011 Korea National Health and Nutrition Examination Survey (KNHANES), using three threshold levels of urinary cotinine ≥100ng/ml, ≥50ng/ml, and ≥30ng/ml.ResultsThe weighted prevalence of urinary cotinine levels of ≥100, ≥50, and ≥30 ng/mL in the whole study population was 34.7%, 37.1%, and 41.1%, respectively. Male sex, younger age, elementary school graduation, household income in the ≤24th percentile, service and sales workers and assembly workers, and high-risk alcohol drinking were associated with a higher prevalence of urinary cotinine level of ≥ 50 or 30 ng/mL, after we adjusted for age, sex, education level, number of family members, household income, occupation, and alcohol drinking.Logistic regression analyses were performed using the aforementioned variables as covariates to identify factors independently associated with cotinine-verified smoking. Men had a higher risk than women of having a urinary cotinine level of ≥50 ng/mL (OR 4.67, 95% CI 4.09–5.32, p < 0.001). When subjects ages 19–29 years were used as controls, adults ages 30–39 years had a 1.19-fold (CI 1.02–1.39, p = 0.026) higher risk of having a urinary cotinine level of ≥50 ng/mL. College graduates had a 32% lower risk of having a urinary cotinine level of ≥50 ng/mL than elementary school graduates (p < 0.001).A household income in the 25–49th percentile (OR 0.82, 95% CI 0.69–0.98, p = 0.026), 50–74th percentile (OR 0.64, 95% CI 0.53–0.76, p < 0.001), or ≥75th percentile (OR 0.64, 95% CI 0.53–0.77, p < 0.001) was associated with a lower risk of having a urinary cotinine level of ≥50 ng/mL compared to a household income in the ≤24th percentile. High-risk (OR 2.75, 95% CI 2.37–3.18, p < 0.001) and intermediate-risk (OR 2.04, 95% CI 1.82–2.30, p < 0.001) alcohol drinking were associated with having a urinary cotinine level of ≥50 ng/mL compared to low-risk alcohol drinking. Similar to the results of the logistic regression analyses of urinary cotinine ≥50 ng/mL, male sex, younger age, elementary school education, household income in the ≤24th percentile, and high-risk alcohol drinking were significantly associated with having a urinary cotinine level of ≥30 ng/mL. Service and sales workers (OR 1.22, 95% CI 1.01–1.48, p = 0.041) had a significantly higher risk of having a urinary cotinine level of ≥30 ng/mL.ConclusionsBased on a threshold urinary cotinine level of 50 ng/mL, the prevalence of cotinine-verified smoking in a representative sample of Korean adults was 37.1% (men 52.7%, women 15.4%). Younger age, male sex, low education level, service and sales workers, low household income, and high-risk alcohol drinking were associated with the risk of smoking.

Association of Alcohol Drinking Patterns With Presence of Impaired Fasting Glucose and Diabetes Mellitus Among South Korean Adults.

BackgroundWe aimed to investigate the association between alcohol drinking patterns and the presence of impaired fasting glucose (IFG) and diabetes mellitus (DM).MethodsWe used data from the Korean National Health and Nutrition Examination Survey, 2010–2014. The participants were aged ≥30 years and had no previous diagnosis of DM. High-risk drinking was defined as alcohol consumption of ≥7 glasses at a sitting for men, and ≥5 glasses for women. After adjusting for confounding factors, a polychotomous logistic regression analysis was performed to assess the association of drinking patterns with IFG and DM.ResultsFor men, high-risk drinking was associated with higher odds ratios (ORs) of IFG (2–4/month, OR 1.51; 95% confidence interval [CI], 1.13–2.04; 2–3/week, OR 1.79; 95% CI, 1.38–2.33; and ≥4/week, OR 2.24; 95% CI, 1.65–3.03) and of DM (2–4/month, OR 2.12; 95% CI, 1.20–3.77; 2–3/week, OR 1.78; 95% CI, 1.05–3.03; and ≥4/week, OR 2.98; 95% CI, 1.72–5.17). For women, high-risk drinking was associated with higher risk of IFG (2–4/month, OR 1.51; 95% CI, 1.04–2.21; 2–3/week, OR 3.19; 95% CI, 2.20–4.64; and ≥4/week, OR 2.23; 95% CI, 1.23–4.06), but not of DM, compared with non-high-risk drinkers who consumed alcohol ≤1 day/month. Non-high-risk drinkers who consumed alcohol ≥4 days/week had higher ORs of DM in men, but lower ORs of DM in women compared with non-high risk drinkers who consumed alcohol ≤1 day/month.ConclusionsCompared with non-high-risk alcohol drinking, even occasional high-risk alcohol drinking was associated with a higher risk of IFG in men and women, and DM in men. Nearly daily non-high-risk alcohol drinking was associated with a higher risk of DM in men and lower risk of DM in women.

Associations between high-risk alcohol consumption and sarcopenia among postmenopausal women.

Sarcopenia is an age-related process, leading to cardio-metabolic diseases and disabilities. High-risk drinking is also closely related to diabetes, hypertension, and dyslipidemia, which are modifiable risk factors for sarcopenia. In the present study, we aimed to investigate the association between alcohol-drinking patterns and sarcopenia in Korean postmenopausal women. Data from 2,373 postmenopausal women were analyzed from the 2008 to 2011 Korean National Health and Nutrition Examination Survey. We defined sarcopenia as two standard deviations below the sex-specific means of the appendicular skeletal muscle/weight (percentage) values of a young reference group. Participants were categorized into three groups according to alcohol-drinking patterns, as assessed by the Alcohol Use Disorders Identification Test questionnaire. The odds ratios and 95% confidence intervals for sarcopenia were calculated using multiple logistic regression analyses. In total, 8.2% of Korean postmenopausal women met criteria for sarcopenia. The prevalence of sarcopenia increased from low-risk to high-risk alcohol-drinking groups as follows: 7.6, 11.0, and 22.7%, respectively. Compared with the low-risk group, the odds ratio (95% confidence interval) for the high-risk group was 4.29 (1.87-9.82) after adjusting for age, body mass index, systolic blood pressure, total cholesterol, fasting blood glucose, household income, education level, daily calorie intake, current smoking and regular exercise, and household food security status CONCLUSIONS:: High-risk alcohol drinking was associated with a higher risk of sarcopenia in postmenopausal Korean women.

The prevalence of and factors associated with high-risk alcohol consumption in Korean adults: The 2009-2011 Korea National Health and Nutrition Examination Survey.

BackgroundThe consequences of alcohol consumption on health outcomes are largely determined by two separate, but related, dimensions of drinking: the total volume of alcohol consumed and the pattern of drinking. Most epidemiological studies focus on the amount of alcohol consumed and do not consider the pattern of drinking.ObjectivesThis study evaluated the prevalence of and factors associated with high-risk and heavy alcohol drinking in Korean adults.MethodsThis study analyzed 15,215 of the 28,009 participants in the 2009–2011 Korea National Health and Nutrition Examination Survey (KNHANES). High-risk alcohol drinking was defined as Alcohol Use Disorders Identification Test (AUDIT) scores ≥16, which provides a framework for intervention to identify hazardous and harmful drinking patterns as the cause of alcohol-use disorders, according to World Health Organization guidelines.ResultsThe prevalence of high-risk drinking was 15.1%, with the highest prevalence of 17.2% in middle-aged adults (45–64 years). In men, the prevalence of high-risk alcohol drinking was 23.7%, with the highest prevalence found in middle-aged adults. In women, the prevalence of high-risk alcohol drinking was 4.2%, with the highest prevalence found in younger adults. Men had higher weighted mean AUDIT scores than women (10.0 vs. 4.0, P<0.001), and age was negatively associated with the AUDIT score (P<0.001). Elementary school graduates had higher mean AUDIT scores than senior high school (P = 0.003) or college (P<0.001) graduates. Regarding occupation, clerical support workers (P = 0.002) and service and sales workers (P<0.001) had higher mean AUDIT scores than managers and professionals. Logistic regression analyses of high-risk alcohol drinking using sex, age, education level, number of family members, household income, and occupation as covariates was performed. Women had a lower risk of high-risk alcohol drinking (odds ratio (OR) 0.14, 95% CI: 0.13–0.16, P<0.001) than men. Regarding age, compared to control subjects aged 19–29 years, adults aged 60–69 and older than 70 years had 0.67- (95% CI: 0.51–0.89, P = 0.005) and 0.29-fold (95% CI: 0.20–0.70, P<0.001) lower risks, respectively, of high-risk alcohol drinking, whereas adults aged 30–59 had an increased risk of high-risk alcohol drinking. Using elementary school graduates as controls, senior high school (OR: 0.70, 95% CI: 0.55–0.87, P = 0.002) and college (OR: 0.54, 95% CI: 0.42–0. 70, P<0.001) graduates had lower risks of high-risk alcohol drinking. Regarding occupation, compared to managers and professionals as controls, service and sales workers had a greater risk of high-risk alcohol drinking (OR: 1.36, 95% CI: 1.07–1.73, P = 0.011). The number of family members and household income did not influence high-risk alcohol drinking.ConclusionsIn a representative sample of Korean adults, the prevalence of high-risk alcohol drinking was 15.1%, with the highest prevalence of 28.3% found in middle-aged men (45–64 years). This study suggests that younger age, male sex, low education level, and service and sales workers are at risk for a high-risk drinking pattern.

The Association of Resting Heart Rate with the Presence of Diabetes in Korean Adults: The 2010-2013 Korea National Health and Nutrition Examination Survey.

BackgroundPrevious epidemiologic studies have shown that elevated resting heart rate (HR) is associated with higher cardiovascular disease (CVD) morbidity and mortality. Although the relationship between elevated HR and CVD is well established, the association between resting HR and diabetes has been relatively understudied, particularly in non-Western populations.ObjectivesWe confirmed the association between the presence of type 2 diabetes and resting HR in the Korean adult population using data from the 2010–2013 Korea National Health and Nutrition Examination Survey (KNHANES).MethodsAmong 25,712 adults (≥ 19 years of age) who participated in the 2010–2013 KNHANES, a total of 22,512 subjects completed laboratory examinations and were included in this analysis. The fasting plasma glucose (FPG) level was categorized into the following five groups: normal fasting glucose (NFG) 1 (<90 mg/dL), NFG 2 (90–99 mg/dL), impaired fasting glucose (IFG) 1 (100–110 mg/dL), IFG 2 (111–125 mg/dL), and diabetes (≥ 126 mg/dL).ResultsThe unadjusted weighted resting HRs were 69.6, 69.4, 69.8, 70.1, and 72.0 beats per minute (bpm) in the NFG 1, NFG 2, IFG 1, IFG 2, and diabetes groups, respectively (P<0.001). We assessed the adjusted weighted resting HR according to the FPG level after adjusting for age, sex, smoking history, high risk alcohol drinking, daily energy intake, waist circumference, serum total cholesterol level, serum triglyceride (TG) level, serum white blood cell (WBC) count, serum hemoglobin (Hb), and the presence of hypertension. The adjusted weighted resting HR significantly increased across the FPG groups (P<0.001). The weighted prevalence rates of diabetes were 6.8% (6.2–7.5%), 7.6% (6.7–8.5%), 8.0% (7.0–9.1%), and 11.8% (10.8–12.7%) in subjects with HR ≤ 64, 65–69, 70–75, and ≥ 76 bpm, respectively (P<0.001), after adjusting for the confounding factors mentioned above. Using resting HR ≤ 64 bpm as the control, resting HR ≥ 76 bpm was correlated with the presence of diabetes (adjusted OR 1.83, 95% CI 1.55–2.16, P<0.001). Each 10 bpm increment of HR increased the risk of the presence of diabetes by 35% (P<0.001). This association of high resting HR with the presence of diabetes was not influenced by the status of blood pressure (BP) medication.ConclusionWe demonstrated that higher HR was associated with diabetes in a representative sample of Korean adults. These positive associations were independent of age, sex, current smoking, high risk alcohol drinking, daily energy intake, waist circumference, and the presence of hypertension and other potential confounders. This study suggests that individuals with higher resting HR are at risk of diabetes and that HR might provide an easy and simple surrogate marker for the risk of diabetes.

Nationwide firefighter survey: the prevalence of lower back pain and its related psychological factors among Korean firefighters

The main objective of this study was to assess the prevalence of lower back pain (LBP) and clarify the effect of work-related psychological factors on LBP. Nationwide survey data collected from male Korean firefighters (FIFS) were used. To identify the risk factors (work-related psychological factors such as job stress and depression) affecting LBP, the χ2 test and multivariate logistic regression analyses were conducted. The prevalence of LBP was 19.3% and was highest in the emergency medical service (31.8%) part of FF job types. Within job stress, an uncomfortable physical environment, high mental job demand and organizational injustice were associated with LBP. However, inadequate social support inversely associated with LBP. Depression and high-risk alcohol drinking were related to LBP. LBP was closely related to job stress, depression and alcohol intake. Proper interventions of psychological factors should therefore be addressed to control LBP in FIFS.

Does an elite education benefit health? Findings from the 1970 British Cohort Study.

Background: Attending private school or a higher-status university is thought to benefit future earnings and occupational opportunities. We examined whether these measures were beneficially related to health and selected health-related behaviours in midlife. Methods: Data were from up to 9799 participants from the 1970 British birth Cohort Study. The high school attended (private, grammar or state) was ascertained at 16 years, and the university attended reported at 42 years [categorised as either higher (Russell Group) or normal-status institutions]. Self-reported health, limiting illness and body mass index (BMI) were reported at 42 years, along with television viewing, take-away meal consumption, physical inactivity, smoking and high risk alcohol drinking. Associations were examined using multiple regression models, adjusted for gender and childhood socioeconomic, health and cognitive measures. Results: Private school and higher status university attendance were associated with favourable self-rated health and lower BMI, and beneficially associated with health-related-behaviours. For example, private school attendance was associated with 0.56 [95% confidence interval (CI): 0.48, 0.65] odds of lower self-rated health [odds ratio (OR) for higher-status university: 0.32 (0.27, 0.37)]. Associations were largely attenuated by adjustment for potential confounders, except for those of private schooling and higher-status university attendance with lower BMI and television viewing, and less frequent take-away meal consumption. Conclusions: Private school and higher-status university attendance were related to better self-rated health, lower BMI and multiple favourable health behaviours in midlife. Findings suggest that type or status of education may be an important under-researched construct to consider when documenting and understanding socioeconomic inequalities in health.

Medium and High Risk Alcohol Drinking Increases the Risk of Obesity in Korean Men: Prospective Cohort Analysis Based on the National Health Insurance Data

The prevalence of obesity (Body Mass Index [BMI] ≥ 30.0 kg/m2) among Korean adults, albeit small, has increased rather rapidly over a couple of decades while that of overweight becomes stable. Although moderate drinking has been known for some health benefits, excessive ‐ drinking clearly provides extra energy and may result in unwanted weight gain. However, previous studies on this association have been limited and inconsistent. We estimated the relative risk (RR) of obesity in regards to alcohol drinking among Korean adults based on the health examination (HE) data from the National Health Insurance. We created a 10‐year prospective cohort data set from 2002–3 through 2012–13 period with 1,167409 men and 901,920 women (≥19 years) who were free of cardiovascular disease, cancer and diabetes, and normal weight (18.5 ≤ BMI &lt; 23.0 kg/m2) at baseline (year 2002–3). Alcohol drinking reported on a baseline questionnaire was used to classify subjects into 4 groups based on the WHO‐Criteria for risk of chronic harm. A total of 1,609 men and 2,015 women became obese during 10 year period. After adjusting for age, BMI, smoking status, dietary preference, physical activity, and health insurance premium deciles at baseline, the RRs of becoming obese across drinking groups were 1.00, 0.99 (95% CI: 0.87–1.13) and 1.42 (95% CI: 1.12–1.81) for abstainers, low risk drinking and medium &amp; high risk drinking group, respectively, among men aged 19–49 years at baseline. In men aged 50–64 years at baseline, the corresponding RRs of becoming obese were 1.00, 0.94 (95% CI: 0.65–1.37), and 1.87 (95% CI: 1.12–3.11). On the other hand, RR for obesity was not significantly different in women, possibly due to small number of drinkers. This study clearly revealed that medium to high risk drinking increases the risk of obesity in Korean men and more so in older age. Onto the well‐known physiological and mental harm, chronic excessive drinking among men needs to be dealt with more comprehensive prospect in Korea and government's attention is warranted.Support or Funding InformationThis study was supported by a grant from the National Health Insurance Corporation in 2015.

The Role of Optimal Intervention Strategies on Controlling Excessive Alcohol Drinking and Its Adverse Health Effects

We propose and analyze a mathematical model for alcohol drinking problem. The transmission process is modeled as a social “contact” process between “heavy” alcohol drinkers and “light” alcohol drinkers within an unchanging shared drinking environment. The basic reproductive number of the model is computed and the stability of the model steady states is investigated. Further, the model is fitted to data on alcohol drinking for Cape Town and Gauteng, South Africa. In addition, the basic model is extended to incorporate three time dependent intervention strategies. The control functions represent the efforts and policies aimed at weakening the intensity of social interactions between light and heavy drinkers and increase the fraction of treated individuals who permanently quit alcohol drinking. Optimal control results suggest that effective control of high-risk alcohol drinking can be achieved if more resources and efforts are devoted on weakening the intensity of social interactions between light and heavy drinkers.

Health Behaviour and Body Mass Index Among Problem Gamblers: Results from a Nationwide Survey

Problem gambling is a serious public health issue. The objective of this study was to investigate whether past year problem gamblers differed from non-problem gamblers with regard to health behaviour and body mass index (BMI) among Danes aged 16years or older. Data were derived from the Danish Health and Morbidity Surveys in 2005 and 2010. Past year problem gambling was defined using the lie/bet questionnaire. Logistic regression analyses were used to examine the association between past year problem gambling and health behaviour and BMI. Problem gambling was associated with unhealthy behaviour and obesity. The odds of smoking was significantly higher among problem gamblers than among non-problem gamblers. Further, the odds of high-risk alcohol drinking and illicit drug use were significantly higher among problem gamblers. The prevalence of sedentary leisure activity, unhealthy diet pattern and obesity was higher among problem gamblers than among non-problem gamblers. The associations found in this study remained significant after adjustment for sex, age, educational and cohabiting status as well as other risk factors. Our findings highlight the presence of a potential, public health challenge and elucidate the need for health promotion initiatives targeted at problem gamblers. Furthermore, more research is needed in order to understand the underlying social mechanism of the association between problem gamblers and unhealthy behaviour.

부모의 고위험 음주 행동이 자녀의 건강행동에 미치는 영향

이 연구는 2009년 지역사회 건강조사 자료를 활용하여 부모의 고위험 음주행동이 자녀의 건강행동에 미치는 영향을 조사하여 가족의 건강문제의 예방 및 관리를 위한 기초자료를 제공하고자 하는 목적에서 이루어 졌다. 대상은 19세 이상의 자녀를 둔 세대 중 고위험 음주에 노출된 16,383명을 선택하여 각 ID별로 부모가 고위험 음주자인 916명을 분류하여 빈도분석, 카이제곱 검정과 로지스틱 회귀분석을 실시하였다. 고위험 음주 부모의 자녀가 정상인 음주부모의 자녀에 비해 고위험 음주행동이(p<0.01)이 높았으며 부정적 건강행태에 영향을 미쳤다. 그러므로 고위험음주들에 대한 가족형 보건교육이 제도적으로 필요함을 고려하여 음주로 인한 문제의 해결이 가정에서부터 이루어져야 함을 제안한다. This study was performed to examine the impact on the health behaviors of the children by their parents' drinking behaviors. We used the data from a community health survey in 2009. The subjects were selected the household that had a child older than 19, and then among them, chose those 916 parents of highly risky drinking exposition among 16,383 control parents. The collected data was analyzed by frequency, chi-square test, and logistic regression analysis, using SPSS 18.0k program. Parent's high risk drinking behavior was independently associated with children's high risk drinking behavior after adjusting covariates(p<0.01). According to the result of the study, high risk drinking behavior of parents impact highly on the children's high risk alcohol drinking, nutritional behaviors, influenza vaccination, and tooth brushing, so it's necessary to consider a systematic family health education to the high risk drinkers.
