HES 383 – PHYSICAL DIMENSIONS OF AGING Calendar description: Changes in physiological function with age. For students planning to become health professionals.Various dimensions of life, including health and functional capacity, are addressed. Sept 5th 2023 Intro to the course, What is aging? Trends in Canada & Some Important Definitions Prof Gina Whitaker, BSc Kin, PhD The UBC Okanagan Campus and the City of Kelowna are located on the traditional, ancestral, and unceded territory of the Syilx Okanagan Nation. YOUR PROF: GINA WHITAKER • BSc Kinesiology, minor Molecular Biology (SFU Burnaby) • PhD Cellular and Physiological Sciences (UBC Vancouver) • Instructor at SFU Biomedical Physiology & Kinesiology • Instructor in HES at UBC Okanagan since 2017 • HES Undergraduate Coordinator Prof Gina’s Contact Info: Office hours: Tuesdays 2pm – 3:30pm and Thursdays 10- 11:30am Email: [email protected] (subject: HES 383) OR via CANVAS inbox YOUR TA FOR HES 383 THIS SEMESTER Jiawen Lim TA’s role in this course: - Marking: Case Studies, Journal Club Presentations & Exams SEMESTER PLAN • Classes Tuesdays and Thursdays 12:30-1:50pm • Asynchronous Components • Case studies (4 in total) • Assigned Readings & videos • Journal Clubs (Peer-led learning) COURSE CONTENT & RESOURCES • Everything (readings, links, etc.) is on Canvas - modules • NO TEXTBOOK • Weekly modules will be published on Fridays (the week before) • Slides will be posted prior to lecture  All course content is structured around weekly learning outcomes COURSE ASSESSMENTS: PARTICIPATION IN CLASS 5% • Using i-clicker cloud • You must answer at least 80% of questions to receive full participation marks • I will ask about 3-4 questions per class COURSE ASSESSMENTS: CASE STUDIES 30% • You will be given 4 case studies over the semester to complete (each worth ~8%) • Due dates: Oct 3rd, Oct 16th, Nov 6th, Dec 4th • They will be posted on Fridays the week prior (so you will have 10 days to complete them) • Each case study will take you 2-4 hours to complete • You can work together with peers in the class but please ensure that you are submitting your own original work COURSE ASSESSMENTS: JOURNAL CLUB 15% • You will be in a group of 3 students this semester and will meet together 4 times online • You will each be given a peer-reviewed research paper in the area of aging physiology • You will take turns presenting your paper, one presenter per meeting x 3 meetings (plus the intro meeting) • On the meetings that you are not presenting, you will come, having read the paper that is being presented and having prepared 2 questions for discussion at the end. Due dates: Oct 3rd (intro activity), Oct 10th, Oct 30th, Nov 27th • 10% for your presentation (8-10 minutes in length) • 5% for participation: Intro to journal club activity and your contribution in the discussion at the 2 journal clubs that you are not presenting at COURSE ASSESSMENTS: MIDTERM & FINAL EXAM • Midterm (20%) on Oct 19th during class time (on paper, in class) • Closed book, approx. ½ multiple choice and ½ short answer • Final exam (30%), date TBA, during the exam period • 20% non-cumulative • 10% cumulative (with direction) COURSE TOPICS PART 1 – An Introduction to Aging (Week 1) • Defining aging / Aging trends in Canada / Healthspan vs Lifespan / Cellular Mechanisms of Aging/ Lifestyle strategies to delay aging PART 2 – Physical Dimensions of Aging in relation to health & disease (Week 2 – 11) • General physical changes; Neuro-muscular, Skeletal; Cardiovascular; Pulmonary; Cognitive • Regular functional decline vs. healthy aging • Assessments, Treatment & Prevention (lifestyle strategies) PART 3 – Successful Aging (Week 12 – 13) • Studies of longevity populations, masters athletes • Aging in Canada: Policies, Best Practices and Future Directions WHAT IS AGING? “The lifelong process of growing older at a cellular, organ, or whole-body level throughout the lifespan” From: Timiras, PS. (2007) Old age as a stage of life: common terms related to aging and methods used to study aging. “Ageing results from progressive accumulation of multiple forms of damage, many of which arise as inevitable by-products of the molecular and cellular processes that underpin living systems. As time goes by, the burden of damage grows and the risk of dying increases.” From, “Is there evidence for a limit to human lifespan?” DEFINING AGE Chronological age The number of years since birth Physiological age Also known as functional age. Calculated based on your risk factors for chronic diseases and your functional status Biological age How ‘old’ your cells, tissues and organs are. A function of your genetics (intrinsic factors) and environment (extrinsic factors) Subjective age How old you feel SOME DEFINITIONS • Senescence – Aging in the post-reproductive years • Lifespan – Duration of life of an individual • Life expectancy – Average amount of time of life remaining for a population (same birthdate) and based on age-specific death rates • Health-adjusted life expectancy OR Healthspan – The number of years you are expected to live in good functional health • Longevity – Long duration of life (long lifespan) • Centenarians: • Population Aging – The increasing median age in a population LIFE EXPECTANCY • How long an individual is expected to live • Estimated based on current stats • Factors: year of birth & how old you are now, M/F, other factors (e.g. BMI, BP, smoking, drinking, activity level, job/life satisfaction), genetics Current life expectancy at birth: In Canada males = 80 Years In Canada females = 84 Years Current life expectancy at 65YO: In Canada males = 19.5 Years In Canada females = 22 Years GLOBAL TRENDS IN LIFE EXPECTANCY Figure 3.1. Life expectancy at birth, 1970 and 2019 (or nearest year) CANADA – AN AGING POPULATION • By 2031 it is predicted that one in four Canadians will be 65+ A clear example of population aging 90 YEARS OF CHANGE IN LIFE EXPECTANCY What is the reason for this increased trend over the years? Yves Decady and Lawson Greenberg. 2014. “Ninety years of change in life expectancy” Health at a Glance. July. Statistics Canada Catalogue no. 82-624-X. CANADA – AN AGING POPULATION What is the fastest growing age-group in Canada? CANADA – AN AGING POPULATION • By 2031 it is predicted that one in four Canadians will be 65+  What does that mean for our society? The fastest growing age group since 2011 = Centenarians CANADA STILL NOT AS OLD AS OTHER COUNTRIES Our life expectancy has increased, but does this mean that we will just spend more years in poor functional health?
