Relationship between pulse pressure and body mass index in active-duty Royal Thai Army personnel in Thailand.

BACKGROUND: Elevated pulse pressure (PP) is a robust independent predictor of cardiovascular diseases. The relationship between PP and body mass index (BMI) was presented in a few studies. However, the findings were inconsistent. Therefore, the aim of the present study is to identify the association between elevated PP and BMI using a large sample of active-duty Royal Thai Army (RTA) personnel. METHODS: A cross-sectional study was conducted through the use of the dataset obtained from the annual health examination database of RTA personnel in Thailand in 2022. BMI 25.0-29.9 kg/m2 was classified as obesity I, whereas BMI ≥ 30.0 kg/m2 was classified as obesity II. Elevated PP was defined as PP ≥ 50 mmHg. Multivariable linear regression and log-binomial regression models were utilized for determining the association between elevated PP and BMI. RESULTS: A total of 62,113 active-duty RTA personnel were included in the study. The average BMI was 25.4 ± 3.8 kg/m2, while the average PP was 50.1 ± 11.2 mmHg. Compared to individuals with normal weight, the [Formula: see text] coefficients of PP and BMI were 1.38 (95% CI: 1.15-1.60) and 2.57 (95% CI: 2.25-2.88) in individuals with obesity I and obesity II, respectively. Effect modification by high blood pressure (BP) on the association between elevated PP and BMI was observed. Among participants with normal BP, in comparison with BMI of 18.5-22.9 kg/m2, the adjusted prevalence ratio (PR) for elevated PP was 1.23 (95% CI: 1.19-1.28) and 1.41 (95% CI: 1.35-1.48) in those with obesity I and obesity II, respectively. Meanwhile, among individuals with high BP, the adjusted PR for elevated PP was 1.05 (95% CI: 1.01-1.08) and 1.09 (95% CI: 1.06-1.13) in those with obesity I and obesity II, respectively. CONCLUSION: PP was positively associated with BMI in active-duty RTA personnel. High BP was the modifier of the association between PP and BMI. A weaker association between elevated PP and BMI was observed among RTA personnel with high BP.

Association between raised blood pressure and elevated serum liver enzymes among active-duty Royal Thai Army personnel in Thailand.

BACKGROUND: The relationship between hypertension (HT) and serum liver enzymes was reported in a few studies, but the findings were inconsistent. Therefore, the present study aimed to identify the association between elevated serum liver enzymes and raised BP through the use of a large sample of Royal Thai Army (RTA) personnel. METHODS: The dataset obtained from the annual health examination database of RTA personnel in Thailand was utilized. A total of 244,281 RTA personnel aged 35-60 were included in the current study. Elevated serum liver enzymes were defined as aspartate aminotransferase (AST) or alanine aminotransferase (ALT) ≥ 40 U/L in males and ≥ 35 U/L in females. HT was defined as systolic BP ≥ 140 or diastolic BP ≥ 90 mmHg. A multivariable linear regression model was used to estimate the coefficient and 95% confidence intervals (CI), whereas a multivariable logistic regression model was applied to estimate adjusted odds ratios (AORs) and 95% CI for the association between raised BP and serum liver enzymes. RESULTS: Compared to individuals with SBP < 120 and DBP < 80 mmHg, the ß coefficients of log-transformed AST and ALT were 0.13 (95% CI: 0.12-0.13) and 0.11 (95% CI: 0.11-0.12) in males with HT. Meanwhile, the ß  coefficients of log-transformed AST and ALT were 0.03 (95% CI: 0.02-0.04) and 0.07 (95% CI: 0.05-0.08) in females with HT. In males, HT was associated with elevated AST (AOR: 1.92; 95% CI: 1.85-2.01) and elevated ALT (AOR: 1.43; 95% CI: 1.38-1.48). On the other hand, in females, HT was associated with elevated AST (AOR: 1.42; 95% CI: 1.21-1.66) and elevated ALT (AOR: 1.38; 95% CI: 1.21-1.57). CONCLUSION: Raised BP was positively correlated with elevated AST and ALT in active-duty RTA personnel. Moreover, HT was independently attributed to higher odds of elevated AST and ALT in comparison to optimal BP in both males and females. Furthermore, the relationship between serum liver enzymes and BP was modified by sex.

Prevalence of hypertriglyceridemia among Royal Thai Army personnel and its related cardiometabolic risk factors, from 2017 to 2021.

BACKGROUND: Hypertriglyceridemia is a common health problem independently associated with an increased risk of atherosclerosis cardiovascular diseases (ASCVD), including ischemic heart disease and stroke. This study aims to determine the prevalence of hypertriglyceridemia among Royal Thai Army (RTA) personnel and its behavioral and cardiometabolic risk factors using the RTA personnel database of the physical health examination from 2017 to 2021. METHODS: A serial cross-sectional study was conducted from 2017 to 2021. A total of 257,683 active-duty RTA personnel aged 35-60 years were included in the study. We defined hypertriglyceridemia as fasting triglyceride ≥150 mg/dL. Moreover, we performed a multivariable logistic regression analysis to investigate behavioral and cardiometabolic risk factors for the prevalence of hypertriglyceridemia. The magnitude of the association was presented as an adjusted odds ratio (AOR) with a 95% confidence interval (CI). RESULTS: The hypertriglyceridemia prevalence among RTA personnel was 43.4% (95% CI: 42.9-43.8%) in 2017. It then continuously decreased to 40.3% (95% CI: 39.9-40.7%) in 2020 and slightly rose to 41.0% (95% CI: 40.6-41.4%) in 2021 (p for trend < 0.001). The prevalence of hypertriglyceridemia was higher for males than females (AOR 2.15; 95% CI: 2.07-2.23); RTA personnel aged 40-44 years compared with those aged 35-39 years (AOR 1.05; 95% CI: 1.02-1.08); and RTA personnel residing in the northeast (AOR; 1.15 95% CI: 1.11-1.18) and the north (AOR 1.05; 95% CI: 1.02-1.08) compared with those residing in Bangkok. The independent behavioral factors associated with hypertriglyceridemia included alcohol consumption, smoking, and sedentary behavior. Moreover, cardiometabolic risk factors, including higher body mass index, high fasting plasma glucose (≥ 100 mg/dL), high blood pressure (≥ 140/90 mmHg), and hypercholesterolemia (≥ 200 mg/dL), were significantly related to hypertriglyceridemia. CONCLUSION: Our data demonstrated that hypertriglyceridemia is a frequent health issue, especially among males, participants aged 40-44 years, and RTA personnel residing in the northeast and the north. The prevalence of hypertriglyceridemia in this population was greatly influenced by alcohol consumption, cigarette smoking, and sedentary behavior. Both behavioral and cardiometabolic risk factors are potential targets for intervention to enhance the primary prevention of sequelae of hypertriglyceridemia, including ASCVD.

Association between obesity and new-onset heart failure among patients with hypertension in Thailand.

BACKGROUND: In Thailand, the epidemiological data on the relationship between obesity and heart failure (HF) among high-risk populations was limited. We assessed the association between body mass index (BMI) and the new-onset HF among people with hypertension (HTN), and also assessed the effect modifier of uncontrolled HTN on this association. METHODS: We analyzed the data obtained from the 2018 Thailand DM/HT study database. Thai people with HTN aged 20 years and older receiving continuous care at outpatient clinics in hospitals nationwide were included. The new-onset HF was defined regarding the ICD-10 as I50 in the medical records within 12 months. Obesity was defined as BMI ≥ 25 kg/m2. Multivariable log-binomial regression analysis was used to determine the association between BMI and new-onset HF and presented as the adjusted risk ratio (aRR) and 95% confidence interval (CI). RESULTS: A total of 35,756 participants were included in the analysis. In all, 50.0% of the participants had BP control for the last two consecutive visits. The mean BMI was 25.1 ± 4.7 kg/m2. New-onset HF occurred in 75 participants (0.21%; 95% CI 0.17-0.26). After adjusting for potential confounders, an elevated BMI was associated with new-onset HF (p value for quadratic trend < 0.001). In comparison with participants with normal BMI (18.5-22.9 kg/m2), the aRR for new-onset HF was 1.57 (95% CI 0.80-3.07) and 3.97 (95% CI 1.95-8.10) in those with BMI 25.0-29.9, and ≥ 30.0 kg/m2. For participants with obesity, aRR for new-onset HF was 2.05 (95% CI 1.24-3.39) compared to non-obese participants. The study found that among patients with control BP, obesity was associated with a higher risk of new-onset HF with an adjusted RR of 2.33 (95% CI 1.12-4.83). For those with uncontrolled BP, the adjusted RR was 1.83 (95% CI 0.93-3.58), but there was no heterogeneity with p value = 0.642. CONCLUSION: An increased BMI had a higher risk for new-onset HF among Thai people with HTN. Obesity was independently associated with new-onset HF among people with HTN, regardless of uncontrolled HTN. Our findings highlight that weight reduction is crucial for mitigating the risk of HF development in HTN patients, regardless of their BP control status.

Factors associated with electrocardiographic left ventricular hypertrophy among patients with hypertension in Thailand.

BACKGROUND: Left ventricular hypertrophy (LVH) strongly predicts cardiovascular diseases (CVD) and death. One-fourth of Thai adults suffer from hypertension. Nevertheless, the information on LVH among Thai patients with hypertension is not well characterized. We aimed to identify the prevalence and factors associated with electrocardiographic LVH (ECG-LVH) among patients with hypertension in Thailand. METHODS: The present study obtained the dataset from the Thailand Diabetes Mellitus/Hypertension study, which included hypertension patients aged 20 years and older receiving continuous care at outpatient clinics in hospitals nationwide in 2011-2015 and 2018. Meanwhile, those without a record of 12-lead electrocardiography (ECG) were excluded from the analysis. ECG-LVH was defined as the LVH noted regarding ECG interpretation in the medical records. Multivariable logistic regression analysis was utilized for determining factors associated with ECG-LVH and presented as the adjusted odds ratio (AOR) and 95% confidence interval (CI). RESULTS: From 226,420 hypertensive patients in the Thailand Diabetes Mellitus/Hypertension study, 38,807 individuals (17.1%) with ECG data recorded were included in the analysis. The mean age was 64.8 ± 11.5 years, and 62.2% were women. Overall, 1,557 study participants had ECG-LVH, with an estimated prevalence of 4.0% (95% CI, 3.8-4.2%). Age-adjusted ECG-LVH prevalence among women and men was 3.4 and 5.1%, respectively (P < 0.001). Multivariable analysis determined factors associated with ECG-LVH, including being men (AOR, 1.49; 95% CI, 1.31-1.69), individuals aged 70 to 79 years (AOR, 1.56; 95% CI, 1.20-2.02) and ≥ 80 years (AOR, 2.10; 95% CI, 1.58-2.78) compared to individuals aged less than 50 years, current smokers (AOR, 1.26; 95% CI, 1.09-1.46) compared to those who never smoked, systolic blood pressure ≥ 140 mmHg and diastolic blood pressure ≥ 90 mmHg (AOR, 1.58; 95% CI, 1.30-1.92) compared to systolic blood pressure < 140 mmHg and diastolic blood pressure < 90 mmHg. CONCLUSIONS: The current study illustrated the prevalence of ECG-LVH among Thai patients with hypertension who had ECG recorded and identified high-risk groups who tended to have ECG-LVH. The findings underscore the need for targeted interventions, particularly among high-risk groups such as older individuals, men, and current smokers, to address modifiable factors associated with ECG-LVH.

Rising trends in the predicted 10-year risk of cardiovascular diseases among Royal Thai Army personnel from 2017 to 2021.

Deaths from cardiovascular diseases (CVD) are becoming a growing threat to global health, including in Thailand. The aim of the present study was to identify the recent trends in the predicted 10-year risk of CVD among Royal Thai Army (RTA) personnel from 2017 to 2021. The predicted 10-year risk for CVD was calculated through the use of the 2008 updated version of the risk algorithm derived from the Framingham Heart Study data. The current study included 346,355 active-duty RTA personnel aged 30-60 years. The age- and sex-adjusted mean of the predicted 10-year risk for CVD significantly increased from 10.8% (95% CI: 10.8-10.9%) in 2017 to 11.7% (95% CI: 11.6-11.7%) in 2021 (p for trend < 0.001). The overall age- and sex-adjusted prevalence of intermediate-to-high predicted 10-year risk for CVD remarkably surged from 24.9% (95% CI: 24.4-25.4%) in 2017 to 29.5% (95% CI: 29.0-30.0%) in 2021 (p for trend < 0.001). The modifiable risk factors for CVD, including high systolic blood pressure, high body mass index, and current smoking in this population, should be alleviated to mitigate the risk for CVD in the future.

Trends in Serum Total Cholesterol and High Total Cholesterol Prevalence Among Royal Thai Army Personnel in Thailand, 2017-2022.

INTRODUCTION: High total cholesterol (TC) is a robust-documented risk factor for atherosclerosis cardiovascular diseases. Approximately one-fourth (23.5%) of Thai civilians had high TC. However, the information on high TC among the Royal Thai Army (RTA) personnel is limited. AIM: The study aimed to identify the trends in serum TC and high TC prevalence among RTA personnel from 2017 to 2022. METHODS: A serial cross-sectional study from 2017 to 2022 was conducted. A total of 318,353 active-duty RTA personnel aged 35-60 years were included in the study. High TC was defined as fasting TC ≥ 240 mg/dL. A multivariable log-binomial regression analysis was performed to investigate factors associated with high TC. RESULTS: The overall age- and sex-adjusted high TC prevalence was 26.3% in 2017 and dropped to 22.9% in 2020; then, it increased to 26.4% in 2022 (p for quadratic trend < 0.001). Younger-aged RTA personnel have significantly rising trends in sex-adjusted high TC prevalence over 6 years. In the south, the age- and sex-adjusted high TC prevalence was 24.4% in 2017 and substantially rose to 33.6% in 2022 (p for quadratic trend < 0.001). Meanwhile, in the northeast, it rose by 3.6% over 6 years. High body mass index, high blood pressure, and hyperglycemia were associated with high TC prevalence among this population. CONCLUSION: High TC was a common essential health issue among RTA personnel. Rising trends in mean serum TC and high TC prevalence from 2017 to 2022 were discovered, especially in younger participants and those residing in the south and northeast.

Prevalence, awareness, and control of hypertension and associated factors among Royal Thai Army personnel in Thailand from 2017 to 2021.

Hypertension (HTN) is a potential risk factor for cardiovascular diseases. We aimed to determine the prevalence, awareness, and control of HTN among RTA personnel in Thailand. We conducted a series of cross-sectional studies from 2017 to 2021. HTN was defined by systolic blood pressure (BP) ≥ 140 mmHg or a diastolic BP ≥ 90 mmHg from a physical health examination, a history of HTN diagnosed by medical personnel, or taking antihypertensive medication. A total of 504,484 participants were included in the present study. The overall HTN prevalence was 29.4%. The prevalence of HTN among males was 30.5%, while it was 17.1% among females. Of the RTA personnel with HTN, 35.9% were aware of their condition. The overall control of HTN among RTA personnel with HTN was 15.8% in 2017 and 17.6% in 2021. Behavioral factors associated with HTN were current smoking, alcohol consumption, and sedentary behavior. A higher BMI was associated with higher HTN prevalence and HTN awareness but less likely to have controllable HTN. Male participants, younger individuals, current alcohol use, and sedentary behavior were associated with a lower prevalence of HTN awareness and controlled HTN. Current tobacco use was also associated with a lower prevalence of HTN awareness.

Bacterial etiology and mortality rate in community-acquired pneumonia, healthcare-associated pneumonia and hospital-acquired pneumonia in Thai university hospital.

Pneumonia is caused by infection at the pulmonary parenchyma which constitutes a crucial risk factor for morbidity and mortality. We aimed to determine the mortality rate and its risk factors as well as etiology among inpatients with community-acquired pneumonia (CAP), hospital-acquired pneumonia (HAP) and healthcare-associated pneumonia (HCAP). A hospital-based retrospective cohort study was conducted in a university hospital located in Bangkok, Thailand. A total of 250 inpatients with pneumonia was included in the present study. The inhospital mortality rate was 1.25 (95% CI 0.99-1.56) per 100 person-days. The present study reported that overall pneumonia caused by gram-negative pathogens accounted for 60.5%. P. aeruginosa was a frequent gram-negative pathogen among these participants, especially among patients with HCAP and HAP. Adjusted hazard ratio (AHR) of inhospital mortality among patients with HAP was 1.75 (95% CI 1.01-3.03) times that of those among patients with CAP, while AHR for 28-day mortality among patients with HAP compared with those with CAP was 2.81 (95% CI 1.38-5.75). Individual risks factors including cardiomyopathy, active-smoker and insulin use were potential risk factors for mortality. Initial qSOFA and acid-based disturbance should be assessed to improve proper management and outcomes.

Rising trends in obesity prevalence among Royal Thai Army personnel from 2017 to 2021.

Obesity is an essential health issue leading to noncommunicable diseases (NCDs) as well as atherosclerotic cardiovascular diseases. We aimed to determine the trends in obesity prevalence among Royal Thai Army (RTA) personnel and their associated factors using the health examination of RTA personnel database. A series of cross-sectional studies were conducted from 2017 to 2021. A self-report guide was created using a standardized case report form to obtain demographic characteristics and determine behavioral risk factors. Obesity was defined as BMI [Formula: see text] 25 kg/m2, and a total of 512,476 RTA personnel nationwide were included. Obesity prevalence rose from 42.1% (95% CI 41.7-42.4) in 2017 to 44.2% (95% CI 43.9-44.5) in 2021 (p for trend < 0.001). A significant surge was observed in obesity prevalence among young RTA personnel aged 18-24 years from 23.7% in 2017 to 28.4% in 2021 (p for trend < 0.001). Higher age individuals, male participants and RTA personnel residing in Bangkok tended to have a significantly higher risk for obesity. Further, regular exercise was a protective factor for obesity. Our data emphasized that obesity among the RTA personnel has been continuously rising over one half-decade, especially among young adults.
