Large body mass index and waist circumference are associated with high blood pressure and impaired fasting glucose in young Chinese men

Body Mass Index is Associated with blood pressure and vital capacity in medical students

BACKGROUND

The widely reported associations between body mass index (BMI) and various chronic diseases, such as hypertension and asthma, have garnered significant attention. Nonetheless, there remains a dearth of research dedicated to understanding the health impacts of medical school on the students, who experience considerable academic pressure. In that context, this study was driven by the goal of investigating the intricate interplay between BMI, blood pressure (BP), and vital capacity among medical students.

METHODS

This study included a cohort of 843 medical students enrolled at Southern Medical University who were selected through random cluster sampling. Within this cohort, measurements of height, weight, BP, and vital capacity were taken. Subsequently, both BMI and vital capacity index (VCI) were calculated for each participant. By categorizing the subjects into four groups according to BMI classifications, a comprehensive analysis that included correlation assessments and binomial logistic regression was conducted.

RESULTS

Within the participant pool, 9.4% and 3.8% of participants were classified as overweight and obese, respectively. Additionally, the prevalence of prehypertension, hypertension, and poor VCI was 18.1%, 2.7%, and 13.5%, respectively. Notably, male students exhibited a higher prevalence of the aforementioned health issues than their female counterparts. Correlation analysis revealed that BMI displayed positive associations with systolic blood pressure (SBP), diastolic blood pressure (DBP), and vital capacity (r = 0.372, 0.257, 0.428; P < 0.001). However, an inverse correlation emerged between BMI and VCI (r = -0.284, P < 0.001). Further analysis revealed that overweight and obese individuals faced an elevated risk of high blood pressure ([OR 2.05, 95% CI 1.15-3.67] and [OR 5.44, 95% CI 2.28-13.02], respectively) compared to their normal-weight counterparts. Moreover, these groups also exhibited a higher risk of poor VCI ([OR 5.25, 95% CI 3.04-9.06] and [OR 15.61, 95% CI 6.81-35.81], respectively), while underweight subjects experienced a reduced risk ([OR 0.19, 95% CI 0.07-0.52]).

CONCLUSIONS

BMI demonstrated a notably strong positive correlation with both BP and vital capacity and a negative correlation with VCI. Therefore, for medical students as well as the daily health care of patients, weight control is recommended to better combat obesity-related diseases, for example, cardiopulmonary diseases, gout and diabetes.

Relationship between blood pressure and BMI in young adult population: a national-level assessment in Bangladesh

Young adulthood is a crucial period for major physiological transitions. Environmental changes associated with these transitions can influence health behaviour and health (e.g. poor diet, high body weight and elevated blood pressure (EBP)). Excess body weight can lead to EBP; however, little is known about this relationship among young adults in developing countries. Focusing on Bangladesh, this study assessed the association between BMI and blood pressure (BP) metrics (systolic BP (SBP), diastolic BP (DBP) and BP class (optimal, normal/high normal and elevated)). Sex-specific analyses of these relationships were performed to assess any difference across sexes. Furthermore, associations of overweight/obesity with BP metrics were investigated. Young adults aged 18-24 years (n 2181) were included from nationally representative cross-sectional Bangladesh Demographic and Health Survey 2017-2018. Multivariable linear and multinomial logistic regression models examined the relationships between BMI, overweight/obesity and BP metrics. Findings reveal that higher BMI was associated with higher SBP (0·83; 95 % CI 0·67, 0·99), DBP (0·66; 95 % CI 0·54, 0·74) and higher odds of having EBP (adjusted OR 1·24; 95 % CI 1·17, 1·31). These relationships were stronger among males than females. Moreover, overweight/obese individuals had higher SBP, DBP and higher odds of having EBP than individuals with normal BMI. Strategies to reduce body weight and to improve healthy lifestyle, and awareness and monitoring of BP may help to address these serious health problems, particularly at an early age.

NURSING STUDENTS’ LIFESTYLE AND RELATED FACTORS

ABSTRACT Objective: to determine nursing students’ lifestyle at a university in Mexico, according to personal factors and previous behaviors of Nola J. Pender’s Health Promotion Model. Method: this is a cross-sectional study developed at a public university of Minatitlán, Veracruz, Mexico, in 2019, with nursing students enrolled in the curricular internship course, totaling 130. Data were collected that include sociodemographic, clinical and lifestyle and behavior characteristics through the Health-Promoting Lifestyle Profile I. We used Student’s t-tests, ANOVA and Pearson’s correlation for the analyses. Results: of the 130 participants, 92 (70.8%) were classified as healthy lifestyle and 38 (29.2%) had a moderately healthy lifestyle. Among the scale domains, the physical activity domain was the one with the lowest score. Negative correlations were found between the self-actualization domain and clinical variables, such as blood pressure, Body Mass Index and waist circumference, and also between this domain and the time of cell phone and television use. Conclusion: the lifestyle general classification of most participants was healthy, but the analyzes of the individual domains demonstrate the need for political and clinical interventions that influence nursing students’ health-promoting behaviors.

ESTILO DE VIDA DE ESTUDANTES DE ENFERMAGEM E FATORES RELACIONADOS

RESUMO Objetivo: determinar o estilo de vida de estudantes de enfermagem de uma Universidade no México, segundo fatores pessoais e comportamentos anteriores do Modelo de Promoção da Saúde de Nola J. Pender. Método: estudo transversal desenvolvido em uma Universidade Pública de Minatitlán, Veracruz, México, no ano 2019, com os estudantes de enfermagem matriculados na disciplina de estágio curricular, totalizando 130. Coletaram-se dados que incluem características sociodemográficas, clínicas e de estilo de vida e comportamento por meio da Health-Promoting Lifestyle Profile I. Utilizaram-se os testes T de Student, Anova e correlação de Pearson para as análises. Resultados: dos 130 participantes, 92 (70,8%) foram classificados com estilo de vida saudável e 38 (29,2%) obtiveram estilo de vida moderadamente saudável. Entre os domínios da escala, o de exercício foi o de menor pontuação. Constataram-se correlações negativas entre o domínio autorrealização e variáveis clínicas, tais como pressão arterial, índice de massa corpórea e circunferência abdominal, e também entre esse domínio e o tempo de uso de celular e televisão. Conclusão: a classificação geral do estilo de vida da maioria dos participantes foi saudável, todavia as análises dos domínios individuais demonstram a necessidade de intervenções políticas e clínicas que influenciem os comportamentos promotores de saúde dos estudantes de enfermagem.

Cognition, motor symptoms, and glycolipid metabolism in Parkinson's disease with depressive symptoms

Depressive symptoms and abnormal glycolipid metabolisms are common in patients with Parkinson's disease (PD), but their relationship has not been fully reported. It is not clear whether glycolipid impairments lead to poor cognitive and motor function, and aggravate depressive symptoms. Therefore, we aimed to explore the relationships between glycolipid variables, cognition, motor and depressive symptoms in PD patients cross-sectionally. Two hundred ten PD patients were recruited. Glycolipid parameters and Uric acid (UA) were measured. Depressive symptoms, cognitive function and motor symptoms were assessed using the Hamilton Depression Rating Scale-17 (HAMD-17), the Montreal Cognitive Assessment (MOCA) and the Movement Disorder Society Unified Parkinson's Disease Rating Scale Part-III (UPDRS-III). Depressive PD patients had significantly worse motor symptoms and higher levels of fasting plasma glucose (FPG) than those in non-depressive patients (F = 24.145, P < 0.001). Further, logistic regression analysis indicated that UPDRS-III (OR = 1.039, 95% CI 1.019-1.057, P = 0.044), FPG (OR = 1.447, 95% CI 1.050-1.994, P = 0.024) were independently associated with depression. In PD patients without depression, UA (β = - 0.068, t = - 2.913, P = 0.005) and cholesterol (CHOL) (β = - 3.941, t = - 2.518, P = 0.014) were independent predictors of the UPDRS-III score; in addition, UPDRS-III score was negatively associated with MOCA score (β = - 0.092, t = - 2.791, P = 0.007). FPG levels and motor symptoms were related to depressive symptoms in PD patients. Further, in non-depressive PD patients, UA and CHOL showed putative biomarkers of motor symptoms.
