The Manitoba Personalized Lifestyle Research (TMPLR) Study

Lifestyle factors, such as diet, physical activity and sleep, are associated with the development of many chronic diseases. The objective of The Manitoba Personalized Lifestyle Research (TMPLR) study is to understand how these lifestyle factors interact with each other and additional factors, such as an individual's genetics and gut microbiome, to influence health. This is an exploratory cross-sectional observational cohort study of adults, with extensive phenotyping by objective health and lifestyle assessments, and retrospective assessment of early life experiences, with retrospective and prospective utilization of secondary data from administrative health records. A planned non-random convenience sample of 840 Manitobans aged 30-46 recruited from the general population, stratified by sex (equal males and females), body mass index (BMI; 60% of participants with a BMI >25 kg/m2), and geography (25% from rural areas,). These stratifications were selected based on Manitoba demographics. Lifestyle factors assessed will include dietary pattern, physical activity, cardiovascular fitness and sleep. Additional factors such as medical history, socio-economic status, alcohol and tobacco consumption, cognition, stress and anxiety, and early life experiences will also be documented. A maternal survey will be performed. Body composition and bone density will be measured by dual energy x-ray absorptiometry. Blood pressure, pulse wave velocity, and augmentation index will be measured on two consecutive days. Chronic disease risk biomarkers will be measured in blood and urine samples. DNA will be extracted for genetic analysis. A fecal sample will be collected for microbiome analysis. Participants may provide their Manitoba Personal Health Information Number (PHIN) to link their study data with administrative health records.Lifestyle factors, such as diet, physical activity and sleep, are associated with the development of many chronic diseases.
