Association between neighbourhood walkability and metabolic risk factors influenced by physical activity: a cross-sectional study of adults in Toronto, Canada

Objective To determine whether neighbourhood walkability is associated with clinical measures of obesity, hypertension, diabetes and dyslipidaemia in an urban adult population. Design Observational cross-sectional study. Setting Urban primary care patients. Participants 78 023 Toronto residents, aged 18 years and over, who were formally rostered or had at least 2 visits between 2012 and 2014 with a primary care physician participating in the University of Toronto Practice Based Research Network (UTOPIAN), within the Canadian Primary Care Sentinel Surveillance Network (CPCSSN). Main outcome measures Differences in average body mass index (BMI), systolic and diastolic blood pressure, fasting blood glucose, haemoglobin A1c (HbA1C), total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein and triglyceride between residents in the highest versus the lowest quartile of neighbourhood walkability, as estimated using multivariable linear regression models and stratified by age. Outcomes were objectively measured and were retrieved from primary care electronic medical records. Models adjusted for age, sex, smoking, medications, medical comorbidities and indices of neighbourhood safety and marginalisation. Results Compared with those in the lowest walkability quartile, individuals in the highest quartile had lower mean BMI (–2.64 kg/m2, 95% CI –2.98 to –2.30; p

Metabolic syndrome (MetS) is defined as a group of metabolic disorders that together increase a person ’s chance of developing cardiovascular diseases, including stroke. The component disorders that comprise MetS are central obesity, high blood pressure, high blood sugar, high triglycerides, and low high-density lipoprotein cholesterol (HDL-C) [1]. Body mass index (BMI), waist circumference (WC), w aist-hip ratio (WHpR), and waist-height ratio (WHtR) are anthropometric indices that can be used to define abdominal obesity for MetS diagnosis [2].

Diabetes has grown to become one of the most important public health concerns of our time. A review by the Harvard T.H. Chan School of Public Health has shown that the number of affected people has quadrupled in the last three decades. Type 2 diabetes (T2D), a type of diabetes traditionally occurring in adults and associated with obesity and a sedentary lifestyle, is now the ninth leading cause of death worldwide. It therefore comes as no surprise that this rapidly emerging epidemic is giving rise to a profusion of diabetes-related complications. What are the usual diabetes-related complications? As diabetes is a systemic ...

, Silva RAA Abstract In women, aging is evidenced by physiological hormonal alterations that trigger changes in body composition, emergence of chronic low-grade inflammation, which is an important pre-disposition to the development of chronic diseases such as Systemic Arterial Hypertension (SAH) and Type 2 Diabetes Mellitus (T2DM). Although it is a strong pro-inflammatory nature disorder, little is known about how body composition interferes with inflammatory markers in diabetic and hypertensive elderly women. Therefore, this study's objective was to evaluate the inflammation in diabetic and hypertensive elderly w...

We examined human lung tissue from COPD patients and normal control subjects, and found a substantial increase in p16-expressing alveolar cells in COPD patients. Using a transgenic mouse deficient for p16, we demonstrated that lungs of mice lacking p16 were structurally and functionally resistant to CS-induced emphysema due to activation of IGF1/Akt regenerative and protective signaling.

ConclusionsHigher inflammatory potential of the diet was positively associated with higher total cholesterol levels in women with SLE. These findings suggest that the inflammatory potential of a person’s diet may play a role in lipid profiles in this population. Future intervention studies are needed to build on these results and explore the effect of anti-inflammatory diets on health outcomes in individuals with SLE.

Abstract BACKGROUND: The severity of left ventricular (LV) remodelling is only partially related to the severity of aortic valve stenosis; additional factors, including diabetes, insulin resistance, obesity and metabolic syndrome, may play important roles. Epicardial adipose tissue (EAT), now considered as a metabolically active organ, is also linked to these factors. AIM: To analyse the association between EAT volume measured using computed tomography and LV remodelling in a prospective cohort of patients with aortic stenosis. METHODS: Consecutive asymptomatic patients with at least mild degenerative ao...

Abstract BACKGROUND AND OBJECTIVES: Obesity and diet contribute to the development of hypercholesterolemia; therefore, controlling blood lipid concentration through diet is essential. To understand the role of diet in controlling blood lipid concentration, we evaluated the food and nutrient intakes, anthropometry, and blood lipid concentrations of adults with dyslipidemia with or without lipid-lowering drug use. METHODS AND STUDY DESIGN: For this crosssectional study, three-year data were obtained from the 6th-7th Korean National Health and Nutrition Examination Survey (2015-2017). Patients with dyslipidemia ...
