Health promotions is the process of enabling people to increase control over and to improve their health. (WHO) - involves developing good health habits early and carrying them through adulthood. - For physicians involves teaching people how to acheieve healthy lifestyle and helping at risk people learn behaviours to offset those risks. - psychologists --> development of interventions to help practice health behaviours and change bad ones. - Lalonde report 1974 first suggested need for health promotion approach In Canada there has been a decreases of acute infectious disorders but an increase in preventable disorders. - smoking, poor diet and pphysical inactivity is the leading social.behavioural risk factors. Cancer deaths can be reduced by 50% by decreasing smoking. etc. Modification of health behaviours has 3 beneficial effects: a. reduce deaths due to lifestyle related diseases b. may delay the time of death by increasing individual longevity and life expectancy c. expand the number of years during which a person lives without disease d. decrease the amount of money that is spent on health care each year. Health behaviours - undertaken by people to enhance or maintain health Health habit - health related behaviour that is firmly established and performed automatically - important health habits include: sleeping 7-8 hrs a night, no smoking, eating breakfast everyday, no more than 2 alcoholic drinks a day, regular exercise, not eating between meals, being no more than 10% overweight. Primary prevention: instilling good health habits and changing poor ones. 2 strategies What influences the practice of health behaviours??? - Socioeconomic factors, - age = health habits good in childhood, decrease in adolescence, increase in adulthood - gender, values, personal control, social influence, personal goals, perceived symptoms, access to health care services, place, cognitive Barriers to modifying health behaviours - once helth habits are engrained they are difficult to change - instability of health behaviours - controlled by different factors based on individuals Intervening with children or adolescents - influence of early socialization and parents as role models - teachable moments esp in early childhood (dentist) - closing the window of vulnerability - adolescent health behaviours influence adult health Interventions with at risk people - benefits = prevent/eliminate poor health habits with early identification, providing knowledge, easy to identify other risk factors interacting with target factor. - problems = perceptions, ethics (may bring out depressions), family dynamics issues Theories a.

Based on expectancy value theory - people engage in behaviours in which they succeed c. Self Efficacy (social cog) c.- strong relationship between strong self efficacy and initial health behaviour change. d. The theory of planned behaviour (social cog) d.- health behaviour is a direct result of a behavioural intention (attitudes, subjective norms and perceived control). d.- predicts a broad array of health behaviours. d.- implementation intentions - specific how/when/where of behaviour and plans to deal with barriers. d. e. Transtheoretical model of behaviour change - spiral stage model. e.- stages people go through in long term to bring behavioural change e.-precontemplation: no intention of changing behaviour. unaware. pressured into help e.- contemplation: no commitment to take action but aware of problem. e.- preparation: intend to change behaviours but not s
