Associated Factors with Changes of Metabolic Abnormalities among General Population in COVID-19 Pandemic

Background@#The coronavirus disease-2019 (COVID-19) pandemic has led to restrictions on daily living including social distancing. These restrictions had an impact on the individual's healthy lifestyle and health status. We investigated the associated factors with changes of metabolic abnormalities among general population in COVID-19. @*Methods@#The participants were 43,639 people who received health check-ups twice in 2019 and 2021 during COVID-19 pandemic, at 16 health promotion centers. Metabolic abnormalities were identified according to the third report of the cholesterol education program criteria. Multiple logistic regression analysis was performed to confirm the factors related to changes of metabolic abnormalities during COVID-19. @*Results@#Metabolic syndrome and metabolic abnormalities increased overall during the COVID-19 pandemic. This increase was mostly appeared in males. The occurrence of metabolic syndrome during COVID-19 was associated with 50s and older age (odds ratio [OR], 1.130; 95% confidence interval [CI], 1.019-1.254), attempt to quit smoking (OR, 1.467; 95% CI, 1.171-1.839), start smoking (OR, 1.251; 95% CI, 1.110-1.412), decrease in aerobic exercise (OR, 1.328; 95% CI, 1.162-1.517), and increase in strength exercise (OR, 0.704; 95% CI, 0.592-0.838). @*Conclusions@#The metabolic syndrome is closely related to smoking experience and lack of exercise during COVID-19.

Relationship between Hypertension and Mircroalbuminuria according to Obesity Status in Prediabetes

BACKGROUND: Microalbuminuria (MA) is a predictor for diabetic nephropathy and mortality of cardiovascular disease. Diabetic nephropathy can be prevented by blood glucose and blood pressure control. Koreans have been found to have a significantly higher risk of type 2 diabetes than Caucasians, despite having normal weights. It is necessary to consider obesity status in the prevention of type 2 diabetes. This study aimed to determine the relationship between MA and hypertension according to obesity status in prediabetes.METHODS: This study was retrospectively conducted in 1,183 prediabetes, aged 30-70 years with fasting blood glucose levels of 100-125 mg/dL or hemoglobin A1c levels of 5.7–6.4% who health examinees at 16 health promotion centers from 2015 to 2016. Study subjects were classified according to obesity and hypertension. Obesity is defined as body mass index of ≥25 kg/m². Blood pressure was categorized as follows: normal blood pressure, <120/80 mmHg; prehypertension, 120–139/80–89 mmHg; and hypertension, ≥140/90 mmHg. We analyzed the relationship between MA and hypertension according to obesity using multivariable logistic regression analysis.RESULTS: While both prehypertensive and hypertensive subgroups were significantly associated with MA in the nonobese, the hypertensive subgroup was only associated with MA in the obese. In the combined effects of obesity and hypertension, prediabetes with normal weight and hypertension had the highest risk of MA (adjusted odds ratio, 6.39; 95% confidence interval, 2.90–14.10) compared to those with nonobese and normal blood pressure.CONCLUSIONS: Our findings suggest that nonobese prediabetes with hypertension would need to be more concerned about MA than do obese prediabetes with hypertension.

Experience and Current Use of Heated Tobacco Products in Korean Military Personnel

BACKGROUND: Heat tobacco products (HTPs) are emerging in Korea. There are few studies that investigated the rates of HTPs use among military personnel in Korea. This study was performed to identify the prevalence of HTPs experience and use. Also this study aimed to evaluate the related factors of HTPs experience and use among military personnel in Korea.METHODS: The study subjects were 3,878 military personnel participated health survey for Korean soldiers from November to December in 2018. Binominal logistic regression analysis was performed to confirm the related factors of HTPs experience and use among military personnel in Korea.RESULTS: The HTPs experience and current use rates of study subjects were 17.4% and 8.7%, respectively. And the HTPs experience and current use among military personnel was associated with college/university degree (adjusted odds ratio [aOR] 1.441, 1.377), lance-corporal (aOR 2.049, 5.636), superiors' smoking in military camp (aOR 1.516, 1.567), interest in health (aOR 1.637, 1.571), ever used smoking (aOR 2.817, 3.575), and ever used electronic cigarette (E-cigarette) (aOR 3.129, 1.587).CONCLUSIONS: The HTPs experience and current use among military personnel are closely related to educational level, military level, smoking status of the superiors, interests in health, conventional cigarette smoking, and E-cigarette use.

Factors Related to Smoking Relapse among Military Personnel in Korea: Data from Smoking Cessation Clinics, 2015–2017

BACKGROUND: Relapse is the common situation of smoking cessation attempts. There are few studies that analyzed the related factors of smoking relapse among military personnel. Thus, This study was performed to investigate factors related to smoking relapse among military personnel who participated smoking cessation clinics in Korea. METHODS: The study subjects were 19,874 military personnel who enrolled smoking cessation clinic from January in 2015 to December in 2017. Smoking cessation applied to criteria exhaled carbon monoxide and urine cotinine levels. Binominal logistic regression analysis was performed to confirm related factors of smoking relapse among military personnel who succeed to quit smoking. RESULTS: The smoking relapse rate of study subjects who succeeded in quitting smoking for 1-month was 15.3% after 3-months and 60.8% after 6-months follow-up. The factors associated with relapse smoking included implementing year, past year quit attempts, number or cigarettes smoked per day, regular exercise, blood pressure. Levels of nicotine dependence affected smoking relapse at 3-months follow-up. CONCLUSIONS: Tailored approaches are necessary to reduce the rates of smoking relapse for military personnel who succeeded to quit smoking shortly but relapse back to smoking.

Association between Metabolic Syndrome and Psychological Characteristics in Korean Postmenopausal Women

BACKGROUND: Metabolic syndrome is a major health problem in postmenopausal women, along with psychological issues. Hence, this study was conducted to investigate the relationship between metabolic syndrome and mental health properties targeting middle-aged menopausal women, and analyzed the psychological factors affecting the prevalence of metabolic syndrome. METHODS: The study subjects were 479 postmenopausal women aged 45-64 years, who had taken their routine health screenings from August to October in 2012. The presence of 3 or more of 5 risk factors constitutes diagnosis of metabolic syndrome. Depression, trait anxiety, and stress level were measured by Beck Depression Inventory, State-Trait Inventory, and Brief Encounter Psychological Instrument, respectively. Multiple logistic regression analysis was performed to confirm the relationship between the metabolic syndrome and psychological characteristics. RESULTS: The prevalence of metabolic syndrome in postmenopausal women was 16.5%. Metabolic syndrome was significantly related with trait anxiety (odds ratio [OR]=16.53, P=0.007) and depression (OR=0.16, P=0.012), after adjusting for age, marital status, educational level, monthly income, body mass index, eating habits and exercise. CONCLUSIONS: Trait anxiety and depression were found to be related with the prevalence of metabolic syndrome in postmenopausal women.

Differential Association of History of Premenstrual Syndrome/ Premenstrual Dysphoric Disorder with Vasomotor Symptoms According to Menopausal Stage / 정신신체의학

OBJECTIVES: Within the normal reproductive cycles of women, dramatic fluctuations of sexual hormones occur in the premenstrual and menopausal periods. In both periods, women are vulnerable to mood disturbances and show several somatic complaints. Based on these common clinical profiles and physiological changes, a relationship between vasomotor symptoms and the premenstrual syndrome has been suggested. However, attempts to establish such a link have yielded inconclusive results. The purpose of this study was to investigate the association between histories of premenstrual syndrome and menopausal vasomotor symptoms within different menopausal stages. METHODS: This cross-sectional study recruited Korean women aged 45-64 years who were perimenopausal and postmenopausal from 16 branch offices of the Korean Association of Health Promotion. All subjects completed self-report questionnaires that asked about a history of premenstrual syndromes, vasomotor symptoms, and several other variables. RESULTS: A total of 1054 participants(361 perimenopausal women and 693 postmenopausal women) completed the study. Severity of premenstrual symptoms significantly correlated with postmenopausal vasomotor symptoms, only in late perimenopausal(r=0.213, p=0.010) and early postmenopausal women(r=0.246, p<0.001). After adjusting for several factors related to vasomotor symptoms, a history of premenstrual syndrome was a significant predictor of moderate to very severe vasomotor symptoms in late perimenopausal(OR=5.197, p=0.005) and early postmenopausal women(OR=3.017, p=0.010). CONCLUSIONS: This study suggests that a history of premenstrual syndrome/premenstrual dysphoric disorder is differentially associated with vasomotor symptoms in the menopausal stage. Prospective studies with larger population are needed to confirm these findings.
